Oliguria throughout prolonged laparoscopy is frequent and the anesthesiologist must be nicely versed on this problem and keep away from "chasing the urine output" as this could result in fluid overload [79�82]. The higher arm should be the location for placement of the blood strain cuff and parenteral strains for which speedy entry could additionally be needed. A pneumatic patient warming gadget could be adhesed to the upper extremities and torso or on the decrease extremities up to the level of the hips to help in maintaining affected person temperature all through the case. Patient positioning: retroperitoneal procedures Patient positioning for retroperitoneal procedures is similar to that for transperitoneal operations with a number of noteworthy exceptions. Since the retroperitoneal house presents a smaller general working surroundings and a extra limited area of port entry, a number of maneuvers are critical to optimize both. This position displaces the lateral peritoneal reflection along with the colon in an anterior path [70], doubling the undisturbed anteroposterior size of the retroperitoneal area [71]. This is a vital step to enlarge the rather more restricted floor space for retroperitoneal port insertion. Warming of the patient utilizing these devices or insufflant heaters is essential to keep physique temperature throughout the case, especially in older patients. Special laparoscopic drapes with widened apertures, Velcro straps for cords and tubing, and instrument pockets are commercially obtainable, though a standard paper flank drape can be utilized and the aperture enlarged with scissors to give enough publicity. Channels can additionally be created for the light and digicam cords, as nicely as the insufflation tubing, by pulling up redundant drape and clamping it to itself while the cords are brought out via the ends. Operative site preparation and draping the ipsilateral abdomen and flank are shaved from the realm of the xiphoid to pubis. A solution of providone� iodine (Betadine) or an analogous floor preparation is used to paint the surgical area. During retroperitoneal procedures the set-up is basically a mirror picture of the transperitoneal arrangement excluding the patient place which remains unchanged. Placement of generators towards the foot of the mattress minimizes wire interference with surgeon movements across the working desk. The patient is positioned on the working room desk within the flank or semi-flank orientation with their affected side up as outlined above. The scrub nurse or technician stands on the alternative side of the desk from the first surgeon, which facilitates passage of equipment instantly throughout the operating table. This association eliminates the need for the operating surgeon to remove their eyes from the first monitor to attain behind or to their side to receive devices. The primary tower containing the insufflator, mild supply, and digicam box is positioned throughout from the operating surgeon so they can visually inspect the settings in addition to the pressure readings all through the case. The secondary tower is placed on the same side as the first surgeon for use by the scrub nurse or second assistant. Monitor towers are positioned towards the head of the desk and angled back towards the working surgeon. The height of the monitor should be applicable for the operating surgeon so upward tilting of the pinnacle and subsequent neck fatigue can be prevented. Irrigants are hung on one of many intravenous poles close to the pinnacle of the affected person and the suction canisters are also situated near the anesthetic machine. Disadvantages of this strategy embody the necessity to dissect and retract the colon, spleen, and pancreas on the left, and the liver and duodenum on the proper. The major advantages of the retroperitoneal approach are the restricted dissection required of the bowel, avoidance of areas of intraperitoneal adhesion, and rapid posterior entry to the principle renal artery when performing nephrectomy. Benzoin Open nephrectomy surgical pan Chapter eighty one Renal Surgery for Benign Disease 951 Steps of the process: transperitoneal Step 1: Creation of the pneumoperitoneum and preliminary entry access the affected person is positioned on the desk in a modified flank place, as described above, with the aspect of the operative pathology placed upwards. A 1-cm incision is made via the pores and skin in the lower quadrant simply lateral to the rectus muscle and halfway between the umbilicus and the anterior superior iliac crest in nonobese patients. This location could have to be shifted cephalad and lateral in overweight patients because of the large stomach pannus. A small clamp is utilized to spread the underlying subcutaneous tissues all the way down to the level of the fascia. The preliminary audible "pop" is the puncturing of the fascia, whereas the second represents entry in to the peritoneal cavity. This second sound is generated by the snap of the internal obturator of the needle and often may be felt in the introducing hand in addition to being heard.

Ureteral catheters are sometimes employed to aid within the localization of radiolucent calculi, and relative indications for preoperative stenting embrace solitary renal items, staghorn calculi, obstruction, or anatomic variants [43]. The topic of frequent debate in the adult inhabitants, the simplest management of decrease pole calculi in children has but to be decided. A ureteral stent was placed in 22% of kids, and these authors reported an 88% stone-free price in children younger than 2 years of age in comparison with 71% in children aged 6�11 years [50]. Treatment of proximal ureteral stones has achieved comparable success rates to renal stones in most pediatric collection, although ureteral stenting is extra commonly employed to aid in stone localization and clearance [32]. Treatment of midto-distal ureteral calculi has traditionally been avoided in youngsters because of difficulties with localization over the sacroiliac joint and concern regarding attainable damage to developing reproductive methods [43]. Cystine stones are uniquely challenging because of their durability and excessive recurrence charges. With a most of 30 mm, mean stone measurement within the remedy success group was 14 mm in comparability with sixteen mm within the therapy failure group [36]. In distinction, utilizing two second-generation lithotripters in 148 children and adolescents, Elsobsky et al. Investigating stone-free outcomes with the Dornier DoLi S gadget in 24 kids with giant stone burdens (mean stone dimension 31 mm), Shouman et al. Further research delineating a transparent dimension cut-off 740 Section 5 Stone Management in Urology: Management of Stones in Abnormal Situations between pediatric and adult populations and limitations inherent to a questionnaire-based retrospective examine make utility of these data in kids difficult. While children have been proven to have a higher capacity to clear fragments then adults [54], the presence of residual fragments has been correlated with opposed clinical end result [28]. Patients with residual fragments had a big improve in antagonistic scientific end result in comparison with stonefree topics, and the presence of metabolic issues was associated with fragment progress [28]. For these causes, metabolic evaluations are actually routinely being carried out in children with a history of calculi and every attempt should be made to achieve a stone-free status. As a outcome children are subjected to a number of treatments requiring basic anesthesia [45], which is regarding for the rationale that effects of shock waves on renal tissue are unclear. Recent evidence from the adult inhabitants indicates that shockwave remedy ends in renal vessel vasoconstriction and that renal tubular harm and subcapsular hematoma from cavitation and shear forces are depending on the kilovoltage applied [55]. The benefits of minimal tract dilation embody elevated maneuverability, decreased blood loss, and shorter hospital keep. However, theoretical limitations, together with extended operative instances and impaired visualization from bleeding, imply that this system will not be adequate for very massive stone burdens [43]. Recent advances in instrumentation, similar to smaller nephroscopes (15�18F), balloon dilation Chapter sixty five Management of Pediatric Stone Disease: Endourologic Techniques 741 Table 65. A urine culture 2�3 weeks prior to an elective procedure is mandatory in each pediatric patient, and each try ought to be made to deal with preoperative urinary tract infections and reduce asymptomatic bacteriuria previous to therapy. In some circumstances, together with children with complex anatomy or pre-existing stent/nephrostomy tube placement, even with a adverse preoperative culture, 3�5 days of antibiotic prophylaxis may be warranted. In all circumstances, broad-spectrum intravenous antibiotics must be administered perioperatively (see above). All percutaneous procedures are carried out utilizing basic anesthesia and antibiotic prophylaxis. A heat operating room, body-temperature isotonic irrigant, brief anesthetic induction, short operative occasions, proper draping, and monitoring of physique temperature ought to lower the incidence of hypothermia and hyponatremia [43]. The patient is then repositioned in the susceptible place with the torso elevated at 30� from the table surface with a towel roll [42]. Circumstances that require particular consideration involve kids with spinal anomalies such as spina bifida. In these sufferers, positioning could be a problem as a result of current spinal hardware and limb contracture [71]. In addition, on account of spinal curvature, renal anatomy is altered and the chance of visceral harm and pneumothorax with percutaneous entry is elevated. As a result of spinal curvature and/or reconstruction, renal anatomy may be altered, increasing the chance of visceral damage and pneumothorax with percutaneous access. In these advanced cases, excessive care must be taken to pad all joints within the prone place.

Additionally, some proof suggests a bonus to radical nephrectomy in the presence of metastatic illness for cytoreductive functions [4]. Furthermore, laparoscopic strategies have extended in to the realm of treating higher tract urothelial carcinoma requiring nephroureterectomy. Now within the period of robot-assisted laparoscopic surgical procedure, urologic surgeons are incorporating this technique for nephrectomy and nephroureterectomy. This chapter will evaluation the indications, strategies, and outcomes for laparoscopic and robotic radical nephrectomy and nephroureterectomy. Whenever possible, T1a renal masses are eliminated by way of the usage of a partial nephrectomy [5]. If not amenable to minimally invasive strategies, then an open partial nephrectomy should be thought of. These embody significant coagulopathy or comorbidities that preclude the affected person from undergoing general anesthesia. Reports have been published relating to the minimally invasive administration of a renal vein thrombus, however that is limited to extremely skilled centers [10]. Previous abdominal surgery has not demonstrated an increased threat of both complications or want for conversion. This includes a detailed history and bodily examination, an entire blood count, serum electrolytes, coagulation panel, calcium, and alkaline phosphatase. A bone scan is unnecessary within the absence of bone ache or an elevated alkaline phosphatase. Abdominal imaging could assist in hilar dissection by preoperatively identifying multiple renal arteries or adherent anatomy. Finally, though lymphadenectomy for renal cell carcinoma remains controversial, cautious consideration must be paid on imaging to regional and retroperitoneal lymphadenopathy. Some choose to use a bowel preparation so as to decompress the colon and small bowel for improved visualization and dealing space throughout the abdomen. A single dose of an antibiotic agent is given 30 min prior to the primary incision to cowl pores and skin flora. Sequential compression units are placed on the calves of the patient and initiated prior to the induction of common anesthesia, along with an optional dose of subcutaneous heparin. The patient is then rigorously placed in a modified lateral decubitus position, angled at approximately 30o from the bottom. Both legs are saved straight with a pillow or different padding placed behind the knees for assist. Finally, the abdomen is prepped sterilely, together with the corresponding flank in case of a have to convert to an open procedure. Access the abdomen is insufflated to a strain of 15�20 mmHg using a Veress needle. Once sufficiently insufflated, a 12-mm dilating trocar is positioned with the usage of a 0o lens to guide its position in to the stomach at the degree of the umbilicus. The 0o lens is exchanged for a 30o 10-mm laparoscopic lens, and the belly contents are inspected for any injury from either the Veress needle or the primary trocar.

The Harmonic gadget is right for performing this separation because it limits the amount of capsular oozing. If inflammatory events have occurred throughout the diverticulum, the overlying fat could adhere to and fill the parenchymal melancholy. This may be probed with a laparoscopic aspirating needle to affirm the presence of the underlying stone as a hard area of contact feedback. Theories relating to thinning of the parenchyma on this area include an absence of induction of the metanephric blastema on this area for many who imagine in congenital origins versus resultant scarring and atrophy from inflammation [36�38]. Once the overlying parenchyma has been incised, the diverticulum is irrigated gently to reveal the contained stone. The 10-mm laparoscope is exchanged for the 30o 5-mm lens, which is inserted within the subcostal area for the transperitoneal strategy and within the posterior axillary line 5-mm port for the retroperitoneal approach. The drawstring is then pulled tight on the sac, the port is eliminated, and the drawstring clamped near the skin level. The stones within the entrapment sac are left in situ throughout the peritoneum or retroperitoneum, and the port is then reintroduced. Step 7: Diverticulum ablation and closure of accumulating system the diverticulum is inspected to find its communication with the accumulating system. Identification is facilitated by injection of methylene blue by way of the externalized ureteral catheter or by gentle compression of the renal pelvis if preinsufflation indigo carmine was utilized instead. Both methods end in a stream of bluetinged urine emitting from the world of the connection. The 5-mm laparoscopic argon beam coagulator is right for full ablation of the urothelial lining of the diverticulum, though the again of the electrocautery or Harmonic shears may also be utilized. Repeat injection of methylene blue by way of the externalized stent (or compression of the pelvis if intravenous indigo carmine is utilized) confirms a watertight closure. It is then secured with a number of sutures of 3-0 Vicryl to the wall of the diverticulum using intracorporeal suturing methods. Step eight: Exiting the abdomen, drain placement, and port closure the world of the dissection is inspected for hemostasis once again at low insufflation pressures and all bleeding points are cauterized. The perforated finish of a 15F round Davol drain with the spike removed is inserted, by way of the decrease quadrant port within the transperitoneal method and the lateral-most port within the retroperitoneal method. Placing a clamp on the back-end of the drain prevents launch of the pneumoperitoneum during this maneuver. A grasper is inserted via the port used to bag the specimen and is utilized to place the drain lateral and behind the kidney to monitor for any leakage of urine. The specimen is eliminated under imaginative and prescient of the 5-mm laparoscope inserted via the remaining 5-mm port with the fascial incision enlarged if necessary. The ultimate port is eliminated as beforehand described after evacuation of the pneumoperitoneum. Postoperative care the postoperative care following laparoscopic calycealectomy is identical to that for cyst decortication. If an 982 Section 6 Laparoscopy and Robotic Surgery: Laparoscopy and Robotics in Adults closure of the neck of the calyceal diverticulum or inadvertent dissection in to the collecting chamber at a website other than the connection. If stent placement is unsuccessful in resolving a urinary fistula, more invasive strategies extrapolated from similar eventualities following partial nephrectomy such as percutaneous drainage, tissue adhesive injection, or open exploration could be required [162, 163]. If the drain output remains elevated, a drain fluid creatinine level should be checked, and whether it is markedly elevated above serum levels, the affected person can either be despatched out with the drain till outputs decline, or a double-pigtail stent may be inserted if giant volume urine-laden drainage continues. It has since been proven to be equally efficacious with superior postoperative pain, morbidity, and convalescence in comparability to the open strategy [54]. Laparoscopic fixation of the kidney to the quadratus lumborum fascia could be accomplished via a transperitoneal or retroperitoneal exposure. We, together with different groups, advocate higher pole fixation to the reduce margin of the coronary ligament of the liver, which is finest accomplished by way of a transperitoneal publicity [165]. A retroperitoneal exposure with fixation to the quadratus fascia solely has been described with the port distribution as outlined for retroperitoneal nephrectomy [166]. As previously mentioned, nearly all of nephropexy procedures are carried out on the best with only 10% of instances isolated to the left kidney [49, 59]. Results There have been limited published series on laparoscopic calyceal diverticulectomy with reported stonefree and diverticulum obliteration rates of 92�100% with brief follow-up (< 1 year) [159�161]. Approaches utilized within the literature are split between the transperitoneal and retroperitoneal approaches with mean operative occasions of roughly a hundred thirty min [160]. Complications Any of the intraoperative or postoperative issues associated to entry entry, retraction, dissection, or port closure as described for easy nephrectomy are potential with laparoscopic diverticulectomy.

These new entry gadgets permit the surgeon to insert a couple of instrument (and an optic) via the identical port [30, 31, forty nine, 50]. The articulating devices can be utilized through standard straight trocars, which have been passed via a single web site (usually the umbilicus) to give a way of triangulation (see below) [32, 47]. Fortunately, expertise in optics and instrumentation has just about reached the point the place this is possible. A few novel ideas like prebent instruments have been developed with this type of surgical procedure. Articulating devices have been originally developed to mimic the freedom of movement afforded by the robotic wrist of the da Vinci surgical robot and had been to be used through the traditional straight trocars used by the robotic arms. They have been ideally suited to be used by the primary surgeons doing single-site surgical procedure through the umbilicus utilizing typical straight trocars, giving a sense of triangulation. Articulating instrumentation permits for triangulation to happen intracorporeally regardless of the trocars being adjacent to one another by way of the identical skin incision [32]. It must, nonetheless, be noted that use of this kind of laparoscope does have a learning curve for the assistant holding the scope. In addition to the usage of the brand new units, single-site surgical procedure was also carried out utilizing entry gadgets that were already available, along with regular laparoscopic hand devices [51]. Some of the earlier hand-access units just like the Gelport are suited to single-incision surgical procedure as they allow multiple instruments to be passed through them. They have the extra advantage of permitting the specimen to be eliminated easily after ablative surgeries. Several hundred circumstances have been performed with a major quantity being reported in peer-reviewed journals [52, 53].

According to a evaluate by Baskett, the earliest use of a natural orifice for extirpation of inside organs in dwelling people was doubtless by the traditional Greeks [4]. The first documented description in fashionable times was by Berengario da Carpi who performed the vaginal elimination of a prolapsed uterus in 1517.

This latter case demonstrates the preliminary report of peritoneal access through a pure orifice incision occurred practically two centuries ago, albeit as a complication. Other natural orifices have been additionally used earlier in the modern period for access to internal organs in dwelling sufferers.

Ureteral calculi the treatment of ureteral calculi is comprised of a number of determination factors: the means to make the analysis, what measures are used to confirm the need for surgical intervention, and tips on how to determine the optimal surgical treatment modality. Each option along the choice tree has associated cost considerations that impact the general cost of any treatment strategy. Urgent intervention With the definitive analysis of a ureteral stone, the need for pressing intervention must be entertained based 758 Section 5 Stone Management in Urology: Cost-Effectiveness and Long-Term Stenting anatomy [12, 13]. Spontaneous passage charges vary inversely with stone measurement and increase the more distally within the ureter the stone is located at the time of analysis [12]. They constructed a choice tree that compared the value of each of two pathways of preliminary observation or surgical remedy. Each of these pathways is associated with specific costs: the value of treatment, emergency room and workplace visits, hospitalization, radiographic imaging, surgical procedure, and lost wages for day off work. Because patients who fail the primary therapy will moreover incur the cost of secondary therapy, the general price of a given treatment technique is considerably impacted by the success price of the primary remedy and is influenced by components corresponding to stone size and stone location. In the face of ureteral obstruction and suspected an infection, pressing decompression of the amassing system is obligatory to forestall urosepsis and its sequelae. Both percutaneous nephrostomy and ureteral stent placement have been proven to be efficient for momentary urinary diversion. An extra potential cost concern in favor of nephrostomy is the risk of failed stent placement in some patients with obstructing stones. Percutaneous nephrostomy within the setting of obstruction and hydronephrosis is generally extremely successful as a end result of the large, dilated collecting system. Although several collection have reported charges of successful stent placement of roughly 80% [10, 11], stent failures will incur the extra price of salvage nephrostomy. Presuming equal efficacy for amassing system decompression in the acute setting of obstruction and infection, the choice of nephrostomy versus stent placement can be primarily based on secondary elements similar to value, availability of an operating room or an interventional radiologist, location or dimension of the stone, and patient and doctor desire. Medical expulsive remedy the likelihood of spontaneous passage of ureteral calculi depends on stone size, stone location, and ureteral Chapter sixty six Cost-Effective Strategies for Management of Renal and Ureteral Calculi Another American study by Brede et al. Whether this advice will maintain true for patients with stones in different ureteral areas awaits further examine. However, for those stones that fail or are unlikely to pass based mostly on dimension, location, or ureteral or affected person anatomy, surgical intervention have to be thought of. Furthermore, different factors in addition to price affect the choice of surgical therapy, including stone traits, surgeon ability, and affected person desire. Several research have examined the price of treating particular subgroups of sufferers with ureteral calculi. One issue that seems to universally impression the worth of the procedure is the need for hospitalization. In a examine of sufferers with distal ureteral stones during which all sufferers had been hospitalized for at least one night, Kapoor et al. While all studies included expenses for the primary surgical process, Bierkens et al. Other studies included the value of preoperative evaluation [21, 22, 25], while some presumed that these costs would be similar in each teams and therefore excluded them from evaluation. Only two studies particularly evaluated and included the charges associated with complications, together with emergency room care in addition to unplanned hospital admissions or nephrostomy tube/ureteral stent placements related to obstruction [21, 25]. This price was accrued for every day spent within the hospital, undergoing a process, or attending an workplace go to [23]. To account for variations in cost and success rates for the 2 procedures from establishment to institution, determination analysis fashions provide theoretical instruments that, via a sequence of assumptions about remedy choices, outcomes, and price, can be utilized to evaluate the price of totally different remedies. Even the fragility of ureteroscopes, with added repair costs, is balanced by the excessive annual maintenance prices of the lithotripter. Chandhoke used a mannequin to determine the "costeffectiveness index" for various remedies for staghorn calculi. Renal calculi the value of treating renal calculi has not been scrutinized as totally as that for ureteral calculi. However, the value of treating particular subgroups of sufferers with renal calculi, corresponding to staghorn and decrease pole calyceal calculi, has been addressed. For each initial treatment technique, there are possible outcomes, each of which might result in further outcomes. Each various outcome has value penalties, such that the whole value of an initial therapy strategy is the sum of the prices of every individual outcome along the pathway.

Comparison of twoand three-dimensional digicam systems in laparoscopic performance: a novel 3D system with one digicam [published online forward of print November 13 2009]. Initial experience with a brand new laparoscopic ultrasound probe for guided Instruments for closure Port sites which may be 10 mm or wider ought to be closed as the incidence of port-site hernia is as high as 3% [50]. Open suture closure could be carried out utilizing S-retractors, Alice clamps, and a 0-0 suture, but may be tough, particularly in obese sufferers. Several instruments have been developed to simplify the procedure of suture passage through the fascia in to the cavity under direct imaginative and prescient, adopted by suture retrieval with a second cross via the opposite side of the fascia. Initial laparoscopic entry utilizing an optical trocar without pneumoperitoneum is safe and effective in the morbidly overweight. Influence of different trocar tips on belly wall penetration during laparoscopy. Comparison of five completely different entry trocar techniques: evaluation of insertion drive, elimination force, and defect size. A randomized prospective examine of radially increasing trocars in laparoscopic surgical procedure. The trade-off between flexibility and maneuverability: task performance with articulating laparoscopic instruments. Evaluation of a vessel sealing system, bipolar electrosurgery, harmonic scalpel, titanium clips, endoscopic gastrointestinal anastomosis vascular staples and sutures for arterial and venous ligation in a porcine model. Laparoscopic nephrectomy utilizing the EnSeal Tissue Sealing and Hemostasis System: profitable therapeutic software of nanotechnology. Thermal results of laparoscopic saline-enhanced radiofrequency cautery on renal parenchyma in a porcine mannequin. Argon gas embolism in laparoscopic cholecystectomy with the Argon Beam One Coagulator. Laboratory evaluation of laparoscopic vascular clamps using a loadcell device-are all clamps the same Laparoscopic partial nephrectomy with selective control of the renal parenchyma: initial experience with a novel laparoscopic clamp. Adhesion formation related to the use of absorbable staples in comparison to different kinds of peritoneal damage. Multicenter trial to evaluate the protection and potential efficacy of pooled human fibrin sealant for the therapy of burn wounds. Risk elements and the prevalence of trocar website herniation after laparoscopic fundoplication. One arm controls the camera and the remaining two to three arms manipulate surgical instruments. The surgeon sits at the console and is offered with a high-resolution three-dimensional (3D) view of the surgical area. The console is connected to the vision cart and patient cart parts by way of cables. The surgeon sits on the console with fingers inserted in to two master controllers. With computer-assisted surgical procedure, motion scaling may be performed to filter out physiologic tremor, allowing for finer actions [1]. The patient cart has either three or 4 arms, relying on the configuration of the system. Robotic devices can be found with quite lots of instrument tips of 5- or 8-mm diameter. The foot pedals are used to toggle between instrument and digicam actions, reset instrument actions (clutching), or provoke cautery [2].
