Functional Outcome and Complications following Ileal Neobladder Reconstruction in Male Patients without Tumor Recurrence. More than 35 Years of Experience from a Single Center.

PURPOSE: There is a lack of data on true long-term functional outcome of orthotopic bladder substitution. The primary study objective was to report our 35-year clinical experience. MATERIALS AND METHODS: Since October 1985, 259 male patients from a large single center radical cystectomy series with complete followup of more than 60 months (median 121, range 60-267) without recurrence, irradiation or undiversion that might have affected the functional outcome, were included. RESULTS: Median age at radical cystectomy and at survey was 63 (range 23-81) and 75 (range 43-92) years, respectively. Overall 87% of patients voided spontaneously and residual-free. This rate decreased with increasing age at the time of surgery (less than 50 years old 94%, 70 years old or older 82%). Overall day/nighttime continence rates were 90%/82%. These rates decreased with increasing age at the time of surgery from 100%/88% to 87%/80%. The overall pad-free rate was 71%/47%. Bicarbonate use decreased from 51% (5 years) to 19% (25 years). Patients with a followup of more than 20 years had the lowest rate of residual urine and clean intermittent catheterization (0.0%) as well as use of more than 1 pad at daytime/nighttime (6.3%/12.5%) and mucus obstruction (0.0%). Serum creatinine showed only the age related increase. The surgical complication rate was 27% and correlated inversely with functional results (chi-squared 11.227, p <0.005), even when the younger age at the time of surgery (younger than 60 years) was related to higher rates of surgical complications (chi-squared 6.80, p <0.05). CONCLUSIONS: The ileal neobladder represents an excellent long-term option for urinary diversion with an acceptable complication rate.

Unexpected Early Oncologic Mortality after Open Radical Cystectomy for Bladder Cancer: Who Is to Be Blamed?

PURPOSE: To investigate prevalence and variables associated with early oncologic mortality (EOM; within ≥30 to ≤90 days) of open radical cystectomy (RC) for bladder cancer. The unexpected rapidity of tumour recurrence and the huge metastatic burden of these patients drew us to analyse this cohort. METHODS: We reviewed our RC database. All 1,487 patients were treated with curative intent between January 1986 and December 2008. Imaging for staging was done by CT (chest) and CT or MRI (abdomen). Clinical and histopathological variables were recorded until death to determine whether disease- or treatment-related factors were associated with mortality. RESULTS: There were 93 deaths within 90 days of surgery. Twenty-four patients died from early progression to high volume disseminated metastatic disease. Group 1: unresectable tumours, which were never free of disease. Group 2: resectable tumours, considered tumour-free after RC. Group 1 is characterized by local tumour spread and a low distant failure rate. Group 2 has a low local and a high distant failure rate. CONCLUSIONS: Disease related (advanced tumour stage, positive soft tissue surgical margins (+STSM), non urothelial histology, unresectable tumours, atypical occult metastasis), rather than technical factors, had the leading role in EOM. Understaging was universal.

[Surgical treatment of bladder cancer: advances made in the past 50 years]. / Operative Therapie des Harnblasenkarzinoms: Fortschritte der letzten 50 Jahre.

The past 5 decades have seen major advances in the surgical treatment of bladder cancer, which have significantly reduced the morbidity and mortality of the disease. Enhanced understanding of tumour biology as well as a large number of newly developed endoscopic instruments and techniques have contributed to making treatment more successful. Moreover, modified and improved surgical techniques of radical cystectomy have been implemented and the clinical and pathological risk stratification of patients has been improved. Hence, patients are treated differently according to risk groups. Treatment algorithms range from repeated transurethral resections to adjuvant intravesical therapy to radical cystectomy, which may be part of a multimodal approach with curative intent. Celebrating the 50th anniversary of "Aktuelle Urologie", we summarise the most important advances in the treatment of BC since 1969 and report some current trends. Modern endoscopic imaging techniques ("enhanced cystoscopy") and molecular subtyping of BC may further improve risk stratification. Moreover, some initial experience has been made with robot-assisted radical cystectomy, and there are new trends for the standardisation of techniques, concepts of enhanced recovery after surgery, as well as initiatives for the measurement of surgical quality and patient-reported outcomes. We believe that all these current developments may help to further improve the quality of life and therapeutic outcome of patients with BC.

Update of the ICUD-SIU International Consultation on Bladder Cancer 2018: urinary diversion.

PURPOSE: To provide a comprehensive overview and update of the joint consultation of the International Consultation on Urological Diseases (ICUD) and Société Internationale d'Urologie on Bladder Cancer Urinary Diversion (UD). METHODS: A detailed analysis of the literature was conducted reporting on the different modalities of UD. For this updated publication, an exhaustive search was conducted in PubMed for recent relevant papers published between October 2013 and August 2018. Via this search, a total of 438 references were identified and 52 of them were finally eligible for analysis. An international, multidisciplinary expert committee evaluated and graded the data according to the Oxford System of Evidence-based Medicine. RESULTS: The incidence of early complications has been reported retrospectively in the range of 20-57%. Unfortunately, only a few randomized controlled studies exist within the field of UD. Consequently, almost all studies used in this report are of level 3-4 evidence including expert opinion based on "first principles" research. CONCLUSIONS: Complications rates overall following RC and UD are significant, and when strict reporting criteria are incorporated, they are much higher than previously published. Complications can occur up to 20 years after surgery, emphasizing the need for lifelong follow-up. Progress has been made to prevent complications implementing robotic surgery and fast track protocols. Preoperative patient information, patient selection, surgical techniques, and careful postoperative follow-up are the cornerstones to achieve good results.

Development and validation of surgical training tool: cystectomy assessment and surgical evaluation (CASE) for robot-assisted radical cystectomy for men.

BACKGROUND: We aimed to develop a structured scoring tool: cystectomy assessment and surgical evaluation (CASE) that objectively measures and quantifies performance during robot-assisted radical cystectomy (RARC) for men. METHODS: A multinational 10-surgeon expert panel collaborated towards development and validation of CASE. The critical steps of RARC in men were deconstructed into nine key domains, each assessed by five anchors. Content validation was done utilizing the Delphi methodology. Each anchor was assessed in terms of context, score concordance, and clarity. The content validity index (CVI) was calculated for each aspect. A CVI ≥ 0.75 represented consensus, and this statement was removed from the next round. This process was repeated until consensus was achieved for all statements. CASE was used to assess de-identified videos of RARC to determine reliability and construct validity. Linearly weighted percent agreement was used to assess inter-rater reliability (IRR). A logit model for odds ratio (OR) was used to assess construct validation. RESULTS: The expert panel reached consensus on CASE after four rounds. The final eight domains of the CASE included: pelvic lymph node dissection, development of the peri-ureteral space, lateral pelvic space, anterior rectal space, control of the vascular pedicle, anterior vesical space, control of the dorsal venous complex, and apical dissection. IRR > 0.6 was achieved for all eight domains. Experts outperformed trainees across all domains. CONCLUSION: We developed and validated a reliable structured, procedure-specific tool for objective evaluation of surgical performance during RARC. CASE may help differentiate novice from expert performances.

Preoperatively Dilated Ureters are a Specific Risk Factor for the Development of Ureteroenteric Strictures after Open Radical Cystectomy and Ileal Neobladder.

PURPOSE: We evaluated preoperative ureteral obstruction as a risk factor for benign ureteroenteric anastomosis strictures in patients who underwent open radical cystectomy and ileal neobladder diversion. MATERIALS AND METHODS: A total of 953 patients in whom bilateral ileoureterostomy was performed between January 1986 and March 2009 formed the study population. A nonrefluxing Le Duc technique was applied in 357 consecutive patients and a refluxing Wallace type technique was applied in 596. We defined ureteroenteric anastomosis stricture as the need for specific therapy (eg stenting, dilatation or reimplantation) or as proven loss of renal function. Kaplan-Meier analysis was done to calculate the likelihood of ureteroenteric anastomosis stricture development. RESULTS: Median followup in the study population was 65 months. Preoperatively 109 patients had unilateral or bilateral obstructed ureters. Unilateral or bilateral obstruction developed in 107 of the 953 patients (127 reno-ureteral units, including 63 on the right side and 64 on the left side). Of the reno-ureteral units 98 had benign and 29 had malignant ureteroenteric anastomosis strictures. The overall stricture rate due to any cause in preoperatively obstructed ureters was 19.3% at 10 years vs 6.4% in preoperatively undilated ureters. For the refluxing Wallace type technique the 10-year ureteroenteric anastomosis stricture rate was 2.4% for preoperatively undilated and 7.6% for preoperatively obstructed ureters. For the nonrefluxing technique the corresponding rates at 10 years were 14.2% and 35.54%, respectively. CONCLUSIONS: Preoperatively obstructed ureters are at significantly higher risk for benign ureteroenteric anastomosis strictures during the postoperative course after ileal neobladder diversion. Most such Le Duc strictures are bilateral and most such Wallace type strictures are unilateral. The risk of ureteroenteric anastomosis stricture after ureteroenterostomy using the nonrefluxing technique is threefold the risk of the refluxing technique. There was no preponderance of left ureteroenteric anastomosis strictures after each technique.

Single Center Experience with Secondary Urinary Diversion after Initial Radical Cystectomy and Primary Urinary Diversion.

PURPOSE: We evaluate the risk of a second urinary diversion in patients after radical cystectomy and urinary diversion. MATERIALS AND METHODS: We retrospectively analyzed the records of 1,614 patients who underwent urinary diversion from January 1986 to March 2009. The primary diversion was neobladder in 71.9% of male patients and 42.3% of female patients, conduit in 17.6% and 38.6%, and ureterocutaneostomy in 9.5% and 12.5%, respectively. The outcome of interest was the need for a second urinary diversion. RESULTS: A total of 51 second/third diversions in 48 patients formed the study population. Mean time from primary to second diversion was 57 months (range 0 to 286). The indication for cystectomy was oncologic in 28 patients and nononcologic in 23. Conversions were continent to continent (14), incontinent to continent (14), continent to incontinent (13) and incontinent to incontinent (10). Twelve patients had tumor recurrence impacting the initial diversion. In 8 patients the indication was abscess necrosis of the diversion or radiogenic damage. Six patients with renal failure required conversion. All patients with conversion from incontinent to continent had a strong desire to avoid a stoma. Four patients died perioperatively and short bowel syndrome developed in 1 patient. CONCLUSIONS: A second urinary diversion was required in 1.8% of patients with bladder cancer with a heterogenous etiology vs 25% when the underlying disease was nononcologic. Only men with apex sparing cystectomy and women whose bladder had not been removed achieved excellent functional outcomes for later orthotopic reconstruction.

Urinary diversion: how experts divert.

OBJECTIVE: To determine the rates of the available urinary diversion options for patients treated with radical cystectomy for bladder cancer in different settings (pioneering institutions, leading urologic oncology centers, and population based). METHODS: Population-based data from the literature included all patients (n = 7608) treated in Sweden during the period 1964-2008, from Germany (n = 14,200) for the years 2008 and 2011, US patients (identified from National Inpatient Sample during 1998-2005, 35,370 patients and 2001-2008, 55,187 patients), and from Medicare (n = 22,600) for the years 1992, 1995, 1998, and 2001. After the International Consultation on Urologic Diseases-European Association of Urology International Consultation on Bladder Cancer 2012, the urinary diversion committee members disclosed data from their home institutions (n = 15,867), including the pioneering institutions and the leading urologic oncology centers. They are the coauthors of this report. RESULTS: The receipt of continent urinary diversion in Sweden and the United States is <15%, whereas in the German high-volume setting, 30% of patients receive a neobladder. At leading urologic oncology centers, this rate is also 30%. At pioneering institutions up to 75% of patients receive an orthotopic reconstruction. Anal diversion is <1%. Continent cutaneous diversion is the second choice. CONCLUSION: Enormous variations in urinary diversion exist for >2 decades. Increased attention in expanding the use of continent reconstruction may help to reduce these disparities for patients undergoing radical cystectomy for bladder cancer. Continent reconstruction should not be the exclusive domain of cystectomy centers. Efforts to increase rates of this complex reconstruction must concentrate on better definition of the quality-of-life impact, technique dissemination, and the centralization of radical cystectomy.

Management of T1 Urothelial Carcinoma of the Bladder: What Do We Know and What Do We Need To Know?

T1 bladder cancer constitutes approximately 25% of incident bladder cancers, and as such carries an important public health impact. Notably, it has a heterogeneous natural history, with large variation in reported oncologic outcomes. Optimal risk-stratification is essential to individualize patient management, targeting those at greatest risk of progression for aggressive therapies such as early cystectomy, while allowing others to safely pursue bladder-preserving approaches including intravesical bacillus Calmette-Guerrin (BCG). Current strategies for diagnosis, risk-stratification, and treatment are imperfect, but emerging technologies and molecular approaches represent exciting opportunities to advance clinical paradigms in management of this disease entity.
