          Abstract

          Objective

          To compare the pre, intra, and post–operative data between ileal conduit and neobladder urinary diversions during laparoscopic radical cystectomy(LRC).

          Material and methods

          Between 2006 and 2011, 63 patients who underwent LRC and urinary diversion had their data input prospectively into a database and said data used for the analysis. The outcome comparators were the patient demographics, operative time, conversion rate, blood loss, transfusion rate, morphine analgesic requirement, length of hospital stay, complication rates, follow up, and quality of life assessments. A Mantel–Haenszel test was used for dichotomous data and an inverse variance method was used for continuous data. P values less than 0.5 were considered significant

          Results

          Thirty–nine patients (60 ±7.11 years) had ileal conduits and 24 patients (57 ±8.68 years) had neobladder urinary diversion. No difference was found (P >0.05) regarding age, BMI, smoking history, TURBT pathology result, blood loss, blood transfusion requirement, conversion rates, length of hospital stay, morphine requirement, complications, or follow–up and quality of life. The neobladder groups did have more previous abdominal operations and had significantly longer operative time.

          Conclusions

          We found no difference between either types of diversion in all comparative aspects except that the neobladder had longer operative times. This is the first comparative study between ileal conduit and neobladder urinary diversion after laparoscopic radical cystectomy and can pose as a bench mark for future comparisons.

          Urinary diversion: ileal conduit to neobladder.

          Richard Hautmann (2003)
          The goals of urinary diversion have evolved from simply diverting the urine through a conduit to orthotopic reconstruction, which provides a safe and continent means to store and eliminate urine with efforts to provide an improved quality of life. We address meaningful points that may help optimize clinical results in patients with an orthotopic bladder substitute. The review involved an objective evaluation of the basic science literature of functional, structural and physiological characteristics of gastrointestinal tissue as a substitute for bladder. Potential problems that may be associated with particular parts of the gut for use in reconstruction are discussed. We also summarize the clinical results and complications of orthotopic reconstruction. In the last 10 years the paradigm for choosing urinary diversion has changed substantially: In 2002 all patients undergoing cystectomy were neobladder candidates. It is critically important to understand the phenomenon of maturation. The motor and pharmacological response of the implanted gut changes dramatically toward that of the bladder. Structural and ultrastructural changes in the ileal mucosa lead to a primitive epithelium similar to urothelium. The need for reflux prevention is not the same as in ureterosigmoidostomy conduit or continent diversion. Reflux prevention in neobladders is even less important than in a normal bladder. When using nonrefluxing techniques, the risk of obstruction is at least twice that after direct anastomosis. Kidney function is not impaired by diversion if stenosis is recognized and managed. Patient health status is more influenced by underlying disease than by diversion. Complications of neobladders are actually similar to or lower than the true rates after conduit formation, in contrast to the popular view that conduits are simple and safe. Some degree of nocturnal leakage is a consistent finding in most reports despite a technically sound operation. The precise pathogenesis of urinary retention requiring clean intermittent catheterization remains uncertain. There are new complications, such as neobladder rupture and mucous tamponade. Orthotopic reconstruction has passed the test of time. In these patients life is similar to that in individuals with a native lower urinary tract. Until a better solution is devised orthotopic bladder reconstruction remains the best option for patients requiring cystectomy.

            Urinary diversion.

            Richard Hautmann, Hassan Abol-enein, Khaled Hafez … (2007)
            A consensus conference convened by the World Health Organization (WHO) and the Société Internationale d'Urologie (SIU) met to critically review reports of urinary diversion. The world literature on urinary diversion was identified through a Medline search. Evidence-based recommendations for urinary diversion were prepared with reference to a 4-point scale. Many level 3 and 4 citations, but very few level 2 and no level 1, were noted. This outcome supported the clinical practice pattern. Findings of >300 reviewed citations are summarized. Published reports on urinary diversion rely heavily on expert opinion and single-institution retrospective case series: (1) The frequency distribution of urinary diversions performed by the authors of this report in >7000 patients with cystectomy reflects the current status of urinary diversion after cystectomy for bladder cancer: neobladder, 47%; conduit, 33%; anal diversion, 10%; continent cutaneous diversion, 8%; incontinent cutaneous diversion, 2%; and others, 0.1%. (2) No randomized controlled studies have investigated quality of life (QOL) after radical cystectomy. Such studies are desirable but are probably difficult to conduct. Published evidence does not support an advantage of one type of reconstruction over the others with regard to QOL. An important proposed reason for this is that patients are subjected preoperatively to method-to-patient matching, and thus are prepared for disadvantages associated with different methods. (3) Simple end-to-side, freely refluxing ureterointestinal anastomosis to an afferent limb of a low-pressure orthotopic reconstruction, in combination with regular voiding and close follow-up, is the procedure that results in the lowest overall complication rate. The potential benefit of "conventional" antireflux procedures in combination with orthotopic reconstruction seems outweighed by the higher complication and reoperation rates. The need to prevent reflux in a continent cutaneous reservoir is not significantly debated, and this should be done. (4) Most reconstructive surgeons have abandoned the continent Kock ileal reservoir largely because of the significant complication rate associated with the intussuscepted nipple valve.

              Laparoscopic and robotic assisted radical cystectomy for bladder cancer: a critical analysis.

              Georges-Pascal Haber, Sebastien Crouzet, Javed I Gill (2008)
              Interest in laparoscopic assisted radical cystectomy (LRC) and robotic assisted radical cystectomy (RRC) is increasing at select centers worldwide. In this update we present the recent worldwide experience and critically evaluate the role of minimally invasive radical surgery for patients with bladder cancer. English-language literature between 1992 and 2007 was reviewed using the National Library of Medicine database and the following key words: laparoscopic, laparoscopic-assisted, robotic, robotic-assisted, and radical cystectomy. Over 102 papers were identified, 48 of which were selected for this review on the basis of their contribution to advancing the field with regard to three criteria: (1) evolution of concepts, (2) development and refinement of techniques, and (3) intermediate- and long-term clinical outcomes. These were evaluated with respect to current techniques and perioperative, functional, and oncological outcomes. Our initial experience is also reported. Minimally invasive techniques can adequately achieve the extirpative aspects of LRC and extended template lymphadenectomy. At most institutions the reconstructive urinary diversion is now typically being performed extracorporeally through a minilaparotomy. Perioperative data indicate that minimally invasive techniques are associated with reduced blood loss, slightly increased operating time, and shorter hospital stay without any significant difference in postoperative complications compared with open surgery. Intermediate-term oncological outcomes appear to be comparable with the open approach. Worldwide experience continues to increase; >700 surgeries have already been performed. LRC or RRC with extracorporeally constructed urinary diversion is a safe and effective operation for appropriate patients with bladder cancer. Perioperative and functional outcomes are comparable with open surgery. More focus on extended lymphadenectomy is necessary to routinely achieve higher node yields. Surrogate and intermediate oncological outcomes are encouraging, and long-term assessment is ongoing.
