Continent urinary reconstruction versus ileal conduit: a contemporary single-institution comparison of perioperative morbidity and mortality

Urinary Diversion Versus Adverse In-Hospital Outcomes After Radical Cystectomy

OBJECTIVE

This study aimed to compare adverse in-hospital outcomes in ileal conduit versus neobladder urinary diversion type after radical cystectomy (RC) in contemporary versus historical patients.

METHODS

Patients were identified within the National Inpatient Sample (NIS 2000-2019). Propensity score matching (PSM; 1:2 ratio) and multivariable logistic regression models (LRMs) were used.

RESULTS

Of 10,533 contemporary (2011-2019) patients, 943 (9.0%) underwent neobladder urinary diversion, while 9590 (91.0%) underwent ileal conduit urinary diversion. Furthermore, of 9742 historical (2010-2019) patients, 932 (9.6%) underwent neobladder urinary diversion and 8810 (90.4%) underwent ileal conduit urinary diversion. After 1:2 PSM, within the contemporary cohort, 943/943 (100%) neobladder versus 1886/9590 (19.6%) ileal conduit patients were included. Similarly, within the historical cohort, 932/932 (100%) neobladder versus 1864/8810 (21.1%) ileal conduit patients were included after PSM. In multivariable LRMs, relative to contemporary neobladder patients, contemporary ileal conduit patients exhibited higher rates of overall postoperative (49.0 vs. 43.6%; multivariable odds ratio [MOR] 1.2), wound (4.2 vs. 2.7%; MOR 1.6), and genitourinary (13.1% vs. 10.0%; MOR 1.3) complications as well as blood transfusions (19.0 vs. 15.6%; MOR 1.3). Conversely, in multivariable LRMs within the historical cohort, no differences were recorded between ileal conduit and neobladder patients.

CONCLUSIONS

Unlike historical comparisons between ileal conduit and neobladder patients, where no differences in adverse in-hospital outcomes were recorded, analyses relying on a contemporary patient cohort subject to PSM and multivariable adjustment revealed higher rates of adverse in-hospital outcomes in 4/13 examined categories. This observation should be considered at informed consent.

Outcomes after robot-assisted radical cystectomy with orthotopic neobladder in women

PURPOSE

To investigate functional, oncological and complication outcomes in women undergoing robot-assisted cystectomy (RARC) with intracorporeal orthotopic neobladder.

METHODS

From a multi-institutional database, we identified females with bladder cancer treated with RARC and intracorporeal orthotopic neobladder. We evaluated the continence rate, short-term oncological outcomes, and complication rates. Analyses were repeated and stratified by the status of preserving gynecological organs.

RESULTS

The study involved 146 patients with the median age 60 years (IQR, 51-66 years). Pelvic organ-preserving procedure (POP) was performed in 77 patients (53%). Overall daytime and nighttime continence rates were 54% and 53%, respectively. For POP, the continence rate was 58% for both daytime and nighttime continence. In the non-POP cohort, the continence rate was 50% for daytime and 49% for nighttime continence. Both groups had balanced positive surgical margin rates (5,3% for POP and 4,7% for non-POP). In the whole cohort, high-grade (Clavien-Dindo ≥3) early and late complication rate was 7,5% and 7,5%, respectively.

CONCLUSIONS

Robot-assisted radical cystectomy with intracorporeal orthotopic neobladder in females demonstrate excellent functional and complication outcomes. Pelvic organ-preserving cystectomy enhances urinary continence rates without adversely affecting surgical margins. Orthotopic neobladder in selected women with bladder cancer, along with pelvic organ-preserving cystectomy may be used for improved functional outcomes without compromising oncological results.

[Urinary diversion in old patients (80+ years)]

With increasing life expectancy there is also an increased need for the management of older (≥ 80 years) patients with the diagnosis of muscle-invasive bladder cancer. Radical cystectomy with urinary diversion is the state of the art treatment (with neoadjuvant chemotherapy, as long as the patient is fit enough). Choosing the best urinary diversion with respect to morbidity compared to functionality and quality of life remains a challenge in these patients. Physical age alone is not decisive for making a decision. A thorough preoperative assessment of medical features, physical and cognitive impairments is more important. Older patients are generally provided with an ileal conduit as an incontinent urinary diversion, as the intervention involves reduced operating times and complexity compared to continent urinary diversions; however, in the case of good health status with an adequate life expectancy and sufficient compliance, continent diversions may be considered even in aged candidates. In the case of multimorbid patients with a high perioperative risk, ureterostomy with permanent ureteric stents is an important alternative. Most importantly, a thorough preoperative counselling enables patients to reach an informed decision.

Comparison of long-term outcomes between ileal conduit and transuretero-cutaneostomy urinary diversion after radical cystectomy: a systematic review and meta-analysis

Background

Urinary diversion in bladder cancer treatment has been a distinguished topic of interest due to varying approaches available. Amongst them, ileal conduit (IC) and transuretero-ureterostomy (TUU) have been popular options in clinical practice. This study would like to compare the long-term outcomes of IC and TUU in patients undergoing RC procedures.

Materials and methods

Literature searches were conducted in MEDLINE, CENTRAL, and EMBASE. Duration of hospitalization, complication rate, quality of life, and survival rate were selected as outcomes. Risk of bias was assessed using the ROBINS-I tool. Outcome measure was pooled using forest plot in Review Manager V.5 for Macintosh. Heterogeneity was measured using the DerSimonian and Laird random-effects model.

Results

Eighteen matching interventional studies were included, 3 were prospective studies. The total number of included samples was 3,689; 1,172 patients of the TUU and 2,517 of IC group. The IC procedure associates with longer hospitalization [mean difference 3.80 [95% confidence interval (CI): 2.27-5.32), p < 0.001, I2 = 92%]. Duration of intensive care did not differ significantly. There were no differences in major complication rates [odds ratio (OR) = 1.45, 95% CI: 0.74-2.84, p = 0.27, I2 = 54%]: stone formation (OR = 1.07, 95% CI: 0.51-2.23, p = 0.48, I2 = 0%), and renal function deterioration (OR = 0.81, 95% CI: 0.39-1.68, p = 0.57, I2 = 0%) between the TUU and IC groups. Quality of life decreased in both groups, and only occurred in the early days after the stoma placement phase. Survival rates were not different among the groups.

Conclusion

TUU is a better UD option as it offers shorter time of hospitalization, with the similar major complications, quality of life, and survival rate compared to IC.

Comparative study on the clinical effect of preparing neobladder with different lengths of ileum

OBJECTIVE

To investigate the relationship between orthotopic U-shaped ileal neobladder volume and bladder function. To investigate the correlation between the volume of the radical cystectomy and the U-shaped ileal neobladder in situ and the function of the bladder.

METHODS

The clinical data of patients undergoing in orthotopic U-shaped neobladder in our hospital were retrospectively analyzed. They were divided into two groups according to the length of the retained ileum. Group 1: The length of the ileum was 25-35cm (including 35cm), and the second group: the length of the ileum was 35-45cm. The basic information, cushion usage, urodynamic examination and complications of the two groups were obtained.

RESULTS

A total of 88 patients were included in the study, including 33 in the first group and 55 in the second group. There was no statistical difference in general data, lymph node collection, lymph node positive rate, positive margin rate, postoperative pathological stage, pathological grade, pathological type, intraoperative blood loss, blood transfusion, postoperative hospital stay, and complications between the two groups of patients. significance. Although the usage of urine pads in group 1 was more than that in group 2 in the short term after operation (P<0.05), it started from the third year after operation. Patients in group 1 used less cushion than group 2 (P<0.05). Urodynamic examination was performed on the patients, and the bladder function of group 1 maintained satisfactory time longer than that of group 2. The total number of deaths in the two groups was 12 and 23, respectively. The 5-year overall survival (OS) rate of group 1 was 53.60%, and the 5-year overall survival rate of group 2 was 52.9%.

CONCLUSIONS

A new bladder formed by cutting the ileum with a length of 25-35 cm (including 35cm) has a longer time to maintain good bladder function than cutting the ileum with a length of 35-45 cm to produce a new bladder.

Mesane kanserinde radikal sistektomi üriner diversiyon operasyonu yapılan hastalarda perioperatif parametrelerin değerlendirilmesi

Purpose: The aim of this study was to evaluate the effect of red blood cell transfusion and/or inotropic/vasopressor agent infusion during intraoperative and postoperative first 24-hour period on 30-day and one-year survival. Materials and Methods: In the final analysis, 133 patients who underwent radical cystectomy and urinary diversion surgery between November 2011 and January 2019 were included in this study. Perioperative anesthesia management early postoperative intensive care patient follow-ups were based on. Results: A statistically significant relationship was found between intraoperative red blood cell transfusion and one-year mortality rates. A statistically significant relationship was found between red blood cell transfusion in the intensive care unit and postoperative 30-day mortality rates. The relationship between vasopressor/inotrope agent infusion in intensive care unit and postoperative 30-day mortality was statistically significant. Conclusion: In radical cystectomy and urinary diversion, intraoperative red blood cell and/or inotrope/vasopressor drug administration, and red blood cell transfusion within first 24 postoperative hours in intensive care unit are associated with lower survival rates in both early and late periods. Future studies should focus on developing and implementing different strategies for perioperative blood management and maintenance of patient hemodynamics that may affect early and late outcomes.

Bricker ileal conduit vs. Cutaneous ureterostomy after radical cystectomy for bladder cancer: a systematic review

PURPOSE

A systematic review of the literature with available published literature to compare ileal conduit (IC) and cutaneous ureterostomy (CU) urinary diversions (UD) in terms of perioperative, functional, and oncological outcomes of high-risk elderly patients treated with radical cystectomy (RC). Protocol Registration: PROSPERO ID CRD42020168851.

MATERIALS AND METHODS

A systematic review, according to the PRISMA Statement, was performed. Search through the Medline, Embase, Scopus, Scielo, Lilacs, and Cochrane Database until July 2020.

RESULTS

The literature search yielded 2,883 citations and were selected eight studies, including 1096 patients. A total of 707 patients underwent IC and 389 CU. Surgical procedures and outcomes, complications, mortality, and quality of life were analyzed.

CONCLUSIONS

CU seems to be a safe alternative for the elderly and more frail patients. It is associated with faster surgery, less blood loss, lower transfusion rates, a lower necessity of intensive care, and shorter hospital stay. According to most studies, complications are less frequent after CU, even though mortality rates are similar. Studies with long-term follow up are awaited.

Preoperative MELD score predicts mortality and adverse outcomes following radical cystectomy: analysis of American College of Surgeons National Surgical Quality Improvement Program

Background

The model for end-stage liver disease (MELD) has been widely used to predict the mortality and morbidity of various surgical procedures.

Objectives

We aimed to correlate a high preoperative MELD score with adverse 30-day postoperative complications following radical cystectomy.

Design and Methods

Patients who underwent elective, non-emergency radical cystectomy were identified from the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database from 2005 to 2017. Patients were categorized according to a calculated MELD score. The primary outcomes of this study were 30-day postoperative mortality, morbidity, and length of hospital stay following radical cystectomy. For further sensitivity analysis, propensity score matching was used to yield a total of 1387 matched pairs and primary outcomes were also assessed in the matched cohort.

Results

Compared with patients with a MELD < 10, those with MELD ⩾ 10 had significantly higher rates of mortality [odds ratio (OR) = 1.71, p = 0.004], major complications (OR = 1.42, p < 0.001), and prolonged hospital stay (OR = 1.29, p < 0.001) on multivariate analysis. Following risk-adjustment for race, propensity-matched groups revealed that patients with MELD score ⩾ 10 were significantly associated with higher mortality (OR = 1.85, p = 0.008), major complications (OR = 1.34, p < 0.001), yet similar length of hospital stay (OR = 1.17, p = 0.072).

Conclusion

MELD score ⩾ 10 is associated with higher mortality and morbidity in patients undergoing radical cystectomy compared with lower MELD scores. Risk-stratification using MELD score may assist clinicians in identifying high-risk patients to provide adequate preoperative counseling, optimize perioperative conditions, and even consider nonsurgical alternatives.

A systematic review and meta-analysis of the long-term outcomes of ileal conduit and orthotopic neobladder urinary diversion

INTRODUCTION

We aimed to perform a systematic review and meta-analysis on the long-term durability, incidence of complications, and patient satisfaction outcomes in ileal conduit (IC) and orthotopic neobladder (ONB).

METHODS

A systematic electronic literature search was performed in Medline, Embase, Cochrane Library, and Scopus using MeSH and free-text search terms "Urinary diversion" AND "Ileal conduit" AND "Neobladder." The search concluded June 19, 2018. Inclusion criteria were those patients who had a cystectomy and required urinary diversion by either IC or neobladder.

RESULTS

In total, 32 publications met the inclusion criteria. Data were available on 46 787 patients (n=36 719 for IC and n=10 068 for ONB). Meta-analyses showed that IC urinary diversions performed less favorably than ONB in terms of re-operation rates, Clavien-Dindo complications, and mortality rates; odds ratios (ORs) and 95% confidence intervals (CIs) were 1.76 (1.24, 2.50), p<0.01; 1.16 (1.09, 1.22), p<0.01; and 6.29 (5.30, 7.48), p<0.01, respectively. IC urinary diversion performed better than ONB in relation to urinary tract infection rates and ureteric stricture rates, OR and 95% CI 0.67 (0.58, 0.77), p<0.01; and 0.70 (0.55, 0.89), p<0.01, respectively.

CONCLUSIONS

Our results show that there is no significantly increased morbidity with ONB compared to IC. Selection of either urinary diversion technique should be based on factors such as tumor stage, comorbidities, surgical experience, and patient acceptance of postoperative sequalae.

Defining postoperative ileus and associated risk factors in patients undergoing radical cystectomy with an Enhanced Recovery After Surgery (ERAS) program

INTRODUCTION

Postoperative ileus (POI) is a common complication of radical cystectomy (RC), occurring in 1.6-23.5% of cases. It is defined heterogeneously in the literature. POI increases hospital length of stay and postoperative morbidity. Factors such as age, epidural use, length of procedure, and blood loss may impact POI. In this study, we aimed to evaluate risk factors that contribute to POI in a cohort of patients managed with a comprehensive Enhanced Recovery After Surgery (ERAS) protocol.

METHODS

A retrospective review of consecutive patients who underwent RC from March 2015 to December 2016 at Vancouver General Hospital was performed. POI was defined a priori as insertion of nasogastric tube for nausea or vomiting, or failure to advance to a solid diet by the seventh postoperative day. To illustrate heterogeneity in previous studies, we also evaluated POI using other previously reported definitions in the RC literature. The influence of potential risk factors for POI, including patient comorbidities, American Society of Anesthesiologists score, gender, age, prior abdominal surgery or radiation, length of operation, diversion type, extent of lymph node dissection, removal date of analgesic catheter, blood loss, and fluid administration volume was analyzed.

RESULTS

Thirty-six (27%) of 136 patients developed POI. Using other previously reported definitions for POI, the incidence ranged from <1-51%. Node-positive status and age at surgery were associated with POI on univariate analysis but not multivariable analysis.

CONCLUSIONS

A large range of POI incidence was observed using previously published definitions of POI. We advocate for a standardized definition of POI when evaluating RC outcomes. POI occurs frequently even with a comprehensive ERAS protocol, suggesting that additional measures are needed to reduce the rate of POI.

Cost-effectiveness analysis of two kinds of bladder cancer urinary diversion: Studer versus Bricker

Background

The purpose of our study was to evaluated the cost-effectiveness of two bladder cancer (BCa) urinary diversions: Studer and Bricker.

Methods

The study included 44 patients with Studer and 40 patients with Bricker. Collected and analyzed the patient's basic characteristics, health care costs, and prognosis survival. The quality-adjusted life-year (QALY) were calculated and verified by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30, Version 3, Chinese version). Cost-effectiveness depends on the incremental cost per QALY. The incremental cost-effectiveness ratio (ICER) was determined using the cost/QALY.

Results

We found the average total cost of the Studer group was $7,173.7±1,390.8, and the Bricker group was $6,545.2±1,458.4. There were significant differences in hospitalization time, total hospitalization expenses, bed cost, comprehensive medical service charge and drugs cost (all P<0.05). The hospitalization time, total hospitalization expenses, bed cost, comprehensive medical service charge, surgical treatment cost and drugs cost in Studer group were higher than those in Bricker group, while there was no significant difference in postoperative complications between the two groups (P=0.858). The ICER of Studer group and Bricker group were $8,535.6±2,027.6/QALY and $11,158.2±2,944.9/QALY, respectively. The ICER of Studer group over Bricker group was $2,514.0/QALY.

Conclusions

We found the Studer group had higher hospitalization time, total hospitalization expenses, bed cost, comprehensive medical service charge, surgical treatment cost, and drugs cost than the Bricker group, but the Studer group had a higher ICER than the Bricker group.

Comparison of a Significant Decline in the Glomerular Filtration Rate between Ileal Conduit and Ileal Neobladder Urinary Diversions after Radical Cystectomy: A Propensity Score-Matched Analysis

Urinary diversion after radical cystectomy is associated with a risk of renal function impairment. A significant decline in the glomerular filtration rate (GFR) (i.e., a ≥30% decline in baseline GFR after 12 months) is associated with long-term renal function impairment. We compared the significant GFR decline between ileal conduit and ileal neobladder urinary diversions 12 months after radical cystectomy. We retrospectively included radical cystectomy patients. Propensity score-matched analysis was performed. The primary outcome was the incidence of a significant GFR decline in ileal conduit urinary diversion (ileal conduit group) and ileal neobladder urinary diversion (ileal neobladder group) 12 months after radical cystectomy. The secondary outcomes were the change of GFR and the incidence of end-stage renal disease (ESRD) in the two groups. After propensity score matching, the ileal conduit and neobladder groups had 117 patients each. The incidence of a significant GFR decline was not significantly different between ileal conduit and ileal neobladder groups (12.0% vs. 13.7%, p = 0.845). The change of GFR and ESRD incidence were not significantly different between the two groups (−8.4% vs. −9.7%, p = 0.480; 4.3% vs. 5.1%, p > 0.999, respectively). These results can provide important information on appropriate selection of the urinary diversion type in radical cystectomy.

Radical cystectomy and W-shaped ileal orthotopic neobladder reconstruction with serosa-lined tunneled ureteroileal anastomoses: A critical analysis of the short-term voiding patterns and urodynamic and functional outcomes

Introduction

We present the short-term voiding patterns and functional and urodynamic outcomes of W-shaped ileal orthotopic neobladder (ONB) following radical cystectomy (RC).

Materials and Methods

Forty-one patients who underwent RC and W-shaped ONB creation between July 2015 and January 2018 were enrolled. Data were analyzed in terms of voiding patterns, urodynamic findings, and functional outcomes at 6 months after surgery. Pouch-related quality of life (QoL) was assessed using European Organization for Research and Treatment of Cancer (EORTC) Generic (QLQ C30), Bladder Cancer-Specific Instruments (QLQ BM30), and IONB-Patient-Reported Outcome (IONB-PRO).

Results

The mean length of follow-up was 19.4 months. At first follow-up, three patients had developed acidosis and rising serum creatinine, and one of them required temporary hemodialysis. One patient developed urethral-pouch anastomotic stricture, which required bladder neck incision. Balloon dilatation was performed for ureteroileal anastomotic stricture and mesh repair for incisional hernia was required in one patient each. Upper tract changes were observed in two patients. During the first and second follow-up, maximum flow rate, voided volume, and postvoid residual urine were 12 ± 4.7 mL/s, 212 ± 120 mL, and 72 + 81 mL and 14.7 ± 5.3 mL/s, 254 ± 168 mL, and 123.7 ± 42.5 mL, respectively. The mean pouch capacity and compliance were 436 ± 103.5 mL and 50.6 ± 17.8 mL/cm H₂O. No patient required clean intermittent catheterization for bladder emptying. In EORTC QLQ-C30 questionnaire, the "Cognitive" domain had the highest and "global QoL" domain had the lowest level of functional scores. "Nausea and vomiting and abdominal bloating and flatulence" domain had the lowest level and "financial difficulties and urinary symptoms" had the highest level of symptomatology in EORTC QLQ questionnaire. The IONB-PRO questionnaire showed the highest level of functioning in "relation life" and the lowest level in "emotional life" domain.

Conclusion

The Ghoneim pouch has a low complication rate with near-normal voiding patterns with an acceptable QoL impairment.

Urinary Tract Infections After Urinary Diversion-Different Occurrence Patterns in Patients With Ileal Conduit and Orthotopic Neobladder

OBJECTIVE

To compare the incidence rate of urinary tract infections (UTIs) and associated pathogens between patients with ileal conduit and patients with orthotopic neobladder urinary diversion.

PATIENTS AND METHODS

The medical records of 179 patients treated with radical cystectomy between 2006 and 2011 were reviewed and data pertaining to postoperative UTI were collected. UTI incidence was reported at 3 months' intervals and compared by diversion type. Preoperative predictors of UTI were evaluated with Cox regression analyses.

RESULTS

The study cohort included 130 patients with ileal conduit and 49 patients with orthotopic neobladder. Patients with a neobladder were younger (P <.001). Median follow-up was 38 months (IQR [interquartile range], 11-63). Median time from surgery to first infection was 1.5 months (IQR, 1-12.5) for patients with a neobladder and 11 months (IQR, 2.5-27) for patients with a conduit (P = .04). During the first 3 months after surgery, 29% of the patients with a neobladder and 8% of the patients with ileal conduit had a UTI episode (P = .001). Rates of UTI did not differ during subsequent follow-up. Diversion type was not associated with UTI on multivariable analysis. Escherichia coli was the most common pathogen in patients with a conduit (58%), and Klebsiella spp. in patients with a neobladder (29%).

CONCLUSION

The risk of UTI is significantly higher in patients with a neobladder during the first 3 months after surgery and comparable to patients with ileal conduit during subsequent follow-up. These findings may facilitate preoperative counseling regarding the expected risk of UTI after urinary diversion.

Comparison of postoperative acute kidney injury between ileal conduit and neobladder urinary diversions after radical cystectomy: A propensity score matching analysis

Ileal conduit and neobladder urinary diversions are frequently performed after radical cystectomy. However, complications after radical cystectomy may be different according to the type of urinary diversion. Acute kidney injury (AKI) is a common complication after surgery and increases costs, morbidity, and mortality of hospitalized patients. This study was performed to compare the incidence of postoperative AKI between ileal conduit and neobladder urinary diversions after radical cystectomy.All consecutive patients who underwent radical cystectomy in 2004 to 2014 in a single tertiary care center were identified. The patients were divided into the ileal conduit and ileal neobladder groups. Preoperative variables, including demographics, cancer-related data and laboratory values, as well as intraoperative data and postoperative outcomes, including AKI, intensive care unit admission rate, and the duration of hospital stay, were evaluated between the groups. Postoperative AKI was defined according to the Kidney Disease: Improving Global Outcome criteria. Propensity score matching analysis was performed to reduce the influence of possible confounding variables and adjust for intergroup differences.After performing 1:1 propensity score matching, the ileal conduit and ileal neobladder groups each included 101 patients. The overall incidence of AKI after radical cystectomy was 30.7% (62 out of 202) and the incidences did not significantly differ between the groups (27 [26.7%], ileal conduit group vs 35 [34.7%], ileal neobladder group, P = 0.268). Intraoperative data, intensive care unit admission rate, and the duration of hospital stay were not significantly different between the groups.Postoperative AKI did not significantly differ between ileal conduit and neobladder urinary diversions after radical cystectomy. This finding provides additional information useful for appropriate selection of the urinary diversion type in conjunction with radical cystectomy.

What should be the patient's preference regarding the choice of hospital in the case of radical cystectomy? Evaluation of early complications after open radical cystectomy in a medium and high volume setting in one hospital

PURPOSE

This study compares early complications after cystectomy and urinary diversion (UD) stratified by the surgical focus and case load of two different department chairpersons in a single institution in two time periods. Creating clear data about complications that can affect the quality of life is an important tool for patients to decide whether and where to perform this extensive surgery.

HYPOTHESIS

A team of surgeons with a clear focus on pelvic surgery leads to lower complication rates in radical cystectomy.

MATERIALS AND METHODS

Radical cystectomy was performed in two separate time periods under the patronage of two different chairmen in the same university hospital. The patient data were analyzed retrospectively and the complications 30 days after surgery were assessed using the Clavien-Dindo classification.

RESULTS

Statistical analysis showed a significant difference in the severity of complications between the two time periods, A and B, in total (P<0.001). When placing patients into subgroups, significantly more complications in period A were also seen concerning sex (male, P<0.001; female, P=0.003), age (<70 years, P<0.001; >70 years, P≤50.001) tumor grade (low grade, P<0.001; high grade, P≤0.001), and UD (ileal conduit, P<0.001; neobladder, P<0.001). In a multivariable analysis, age (P=0.031) and type of UD (P=0.028) were determined as independent predictors for complications in period A. When joining the two periods together, the type of UD (P=0.0417), age (P=0.041), and the time periods (A/B) (P<0.001) show a significant association with the presence of complications.

CONCLUSION

This study compares for the first time surgical complications in two time periods with different case load and surgical focus in one department. Categorization shows that patients should prefer radical cystectomy in centers of excellence or a high-volume hospital in order to keep complications at the lowest possible level and thus have the highest benefit for oncologic outcome and quality of life.

Complications of Radical Cystectomy and Orthotopic Reconstruction

Radical cystectomy and orthotopic reconstruction significant morbidity and mortality despite advances in minimal invasive and robotic technology. In this review, we will discuss early and late complications, as well as describe efforts to minimize morbidity and mortality, with a focus on ileal orthotopic bladder substitute (OBS). We summarise efforts to minimize morbidity and mortality including enhanced recovery as well as early and late complications seen after radical cystectomy and OBS. Centralisation of complex cancer services in the UK has led to a fall in mortality and high volume institutions have a significantly lower rate of 30-day mortality compared to low volume institutions. Enhanced recovery pathways have resulted in shorter length of hospital stay and potentially a reduction in morbidity. Early complications of radical cystectomy occur as a direct result of the surgery itself while late complications, which can occur even after 10 years after surgery, are due to urinary diversion. OBS represents the ideal urinary diversion for patients without contraindications. However, all patients with OBS should have regular long term follow-up for oncological surveillance and to identify complications should they arise.

Comparison of Perioperative Morbidity of Radical Cystectomy With Neobladder Versus Ileal Conduit: A Matched Pair Analysis of 170 Patients

BACKGROUND

The objective of this study was to evaluate if use of an ileal conduit (IC) versus a neobladder (NB) during radical cystectomy (RC) can play a role in the morbidity of the surgical procedure.

PATIENTS AND METHODS

Since 2001 our institution has prospectively maintained a database of more than 500 patients who have undergone RC. The records of 258 patients who received an RC and IC and 121 who received an RC and NB were reviewed for the present study. Using a binary logistic regression model a propensity score was generated for the following factors: sex, age, smoking habit, Charlson score, American Society of Anesthesiology score, preoperative hydronephrosis, and pathologic T stage. Two groups of patients with similar propensity scores were created with a ratio of 1:1, one group who received an IC and another who received an NB. The following features were compared between the 2 groups: blood loss, intraoperative complication rate, time to oral intake resumption, postoperative complication rate (overall, Clavien classification 1-2, Clavien classification 3-5, related to RC, related to urinary reconstruction).

RESULTS

In total, 170 patients were selected; 85 with NB, 85 with IC, and the 2 groups were well matched according to the desired features. No differences were noted for all of the compared features.

CONCLUSION

The morbidity of RC does not seem to be affected by the choice of IC versus NB.

Morphological and functional analysis of a cohort of patients undergoing orthotopic ileal neobladder

INTRODUCTION

This study was conducted between January 2001 and December 2013 to evaluate patient's outcomes after radical cystectomy and orthotopic ileal neobladder from a morphological and functional point of view at a median follow-up of 2 years.

MATERIALS AND METHODS

A total of 48 eligible patents were included. We first report our technical modifications to Studer's neobladder. Sequently, after a medium follow-up of two years, we assessed morphology of the reservoir and voiding functionality of this patients cohort, submitting them to specific questionnaires and to uroflowmetry.

RESULTS

Early and late postoperative data are available for 36 patients. From the morphological follow-up, 2 years after surgery, six patients had hydroureteronephrosis for vescico-ureteral reflux in four cases (11% of total) and uretero-neobladder anastomosis stenosis in the other two (5.6% of total). Neobladder shape always remained spherical, with a relative right lateralization in eight cases (22.2%). Regarding the nine patients subjected to uroflowmetry, seven (77.7%) highlighted the lack of postvoid residual urine, with a maximum urinary flow rate within the normal range in six of them.

DISCUSSION

Improvements in surgical technique may help to reduce complications rate. From uroflowmetry analysis, we can observe that the mean filling pressure following surgery was relatively stable and urinary flow rate was mostly satisfactory. In patients without postvoid residual urine, all referred absence of daily incontinence and good quality of life.

CONCLUSION

From this morpho-functional evaluation, our orthotopic Studer-modified ileal neobladder seems an ideal solution for urinary diversion, presenting functional features similar to native bladder and assuming a well-defined morphology, not changing in time.

Patient and disease-specific factors and their influence on urinary reconstruction choice at a referral center

PURPOSE

To evaluate potential socioeconomic and demographic factors that may influence or be associated with various types of urinary reconstruction (UR) following a radical cystectomy (RC) accounting for existing clinical variables.

METHODS

There were 828 patients that underwent a RC and UR between 2000 and 2013. After excluding patients that did not meet medical or surgical criteria for a continent urinary reconstruction (CUR-orthotopic neobladder or continent catheterizable pouch), there were 714 patients available for analysis. Socioeconomic and demographic data along with disease-specific variables were recorded preoperatively and analyzed to determine a correlation with a particular type of UR.

RESULTS

Non-continent urinary reconstruction (ileal conduit or cutaneous ureterostomies) and CUR accounted for 78.3 % (559/714) and 21.7 % (155/714) of UR following RC, respectively. On univariate analysis, younger age, marital status, employment status, type of insurance, ASA score, and preoperative glomerular filtration rate were significantly associated with CUR (p < 0.01). Travel distance, race, and education level were not factors for UR type. Additionally, there was no significant difference between males and females receiving a CUR. On multivariate analysis, older age [odds ratio (OR) 0.85, p < 0.01], marital status (OR 0.28, p < 0.01), insurance status (OR 0.22, p = 0.04), and higher ASA score (OR 0.50, p < 0.01) remained independent predictors of those less likely to receive a CUR.

CONCLUSION

Predictable socioeconomic and demographic influences exist between the choice of UR after RC. Increasing age corresponds to a decreasing likelihood of receiving a CUR. No significant difference was seen between men and women in undergoing a CUR.

[Differences in morbidity of neobladder versus ileal conduit: a matched pair analysis on 134 patients]

OBJECTIVE

The objective of this study is to evaluate whether performing an ileal conduit (IC) versus a neobladder(NB) during radical cystectomy (RC) can play a role on the morbidity of the surgical procedure.

MATERIALS AND METHODS

At our institution since 2001, a database collecting the data of more than 450 patients who have undergone RC is perspectively maintained.The records of 246 patients submitted to RC and IC and 120 to RC and NB have been reviewed for the present study. By a binary logistic regression model, a propensity score was generated joining these factors: gender,age, smoking habit, Charlson’ comorbidity score, platelet antiaggregants or oral anticoagulant therapy, ASA(American Society of Anesthesiologists) score, hydronephrosis, pathologic T stage, and lymphadenectomy. A group of patients submitted to IC and another to NB having the closer propensity score were created with a matching ratio of 1:1. The following features were compared between the two groups: operative time, blood loss,intraoperative complication rate, and postoperative complications rate (overall, clavien 1-2, clavien ≥, related toRC, relate to urinary reconstruction).Results: One hundred thirty-four patients were selected, 67 submitted to NB, 67 to IC, well matched according to the desired features. No differences were noted for all the compared features.Conclusion: The morbidity of RC does not seem to be dependent on the choice to perform IC versus NB.

Long-term oncologic outcomes after radical cystectomy for bladder cancer at a single institution

The aim of this study was to evaluate our experience using radical cystectomy to treat patients with bladder cancer and to describe the associations between pathologic features and clinical outcomes. All 701 patients who underwent radical cystectomy for bladder cancer were evaluated. The patient population consisted of 623 men and 78 women. The overall 5 and 10 yr recurrence-free survival (RFS) rates were 61.8% and 57.7%, respectively, and the 5 and 10 yr cancer-specific survival (CSS) rates were 70.8% and 65.1%, respectively. Multivariate analysis showed that factors significantly predictive of RFS and CSS included extravesical extension (P = 0.001), lymph node metastasis (P = 0.001), and lymphovascular invasion (P < 0.001 and P = 0.007). The 5 and 10 yr RFS rates for patients with lymph node metastasis were 25.6% and 20.8%, respectively, and the 5 and 10 yr CSS rates were 38.6% and 30.9%, respectively. Adjuvant chemotherapy significantly improved RFS (P = 0.002) and CSS (P = 0.001) in patients with lymph node metastasis. Radical cystectomy provides good survival results in patients with invasive bladder cancer. Pathologic features significantly associated with prognosis include extravesical extension, node metastasis, and lymphovascular invasion. Adjuvant chemotherapy improves survival in patients with advanced stage disease.

Urinary diversion after radical cystectomy for bladder cancer: options, patient selection, and outcomes

CONTEXT

The urinary reconstructive options available after radical cystectomy (RC) for bladder cancer are discussed, as are the criteria for selection of the most appropriate diversion, and the outcomes and complications associated with different diversion options.

OBJECTIVE

To critically review the peer-reviewed literature on the function and oncological outcomes, complications, and factors influencing choice of procedure with urinary diversion after RC for bladder carcinoma.

EVIDENCE ACQUISITION

A Medline search was conducted to identify original articles, review articles, and editorials on urinary diversion in patients treated with RC. Searches were limited to the English language. Keywords included: 'bladder cancer', 'cystectomy', 'diversion', 'neobladder', and 'conduit'. The articles with the highest level of evidence were selected and reviewed, with the consensus of all of the authors of this paper.

EVIDENCE SYNTHESIS

Both continent and incontinent diversions are available for urinary reconstruction after RC. In appropriately selected patients, an orthotopic neobladder permits the elimination of an external stoma and preservation of body image without compromising cancer control. However, the patient must be fully educated and committed to the labour-intensive rehabilitation process. He must also be able to perform self-catheterisation if necessary. When involvement of the urinary outflow tract by tumour prevents the use of an orthotopic neobladder, a continent cutaneous reservoir may still offer the opportunity for continence albeit one that requires obligate self-catheterisation. For patients who are not candidates for continent diversion, the ileal loop remains an acceptable and reliable option.

CONCLUSIONS

Both continent and incontinent diversions are available for urinary reconstruction after RC. Orthotopic neobladders optimally preserve body image, while continent cutaneous diversions represent a reasonable alternative. Ileal conduits represent the fastest, easiest, least complication-prone, and most commonly performed urinary diversion.

Sexual function after non-nerve-sparing radical cystoprostatectomy: a comparison between ileal conduit urinary diversion and orthotopic ileal neobladder substitution

OBJECTIVE

To compare the erectile function (EF) and sexual desire (SD) in men after radical cystoprostatectomy (RCP) who had either an ileal conduit urinary diversion or orthotropic ileal neobladder substitution.

MATERIALS AND METHODS

Eighty one sexually active men with bladder cancer were enrolled in this prospective study. After RCP according to patients' preferences they underwent either ileal conduit urinary diversion (n = 41) or orthotropic ileal neobladder substitution (n = 40). EF and SD were assessed using International Index of Erectile Function (IIEF) questionnaire. Patients were assessed at 4-week before surgery and were followed up at 1, 6, and 12-month postoperatively using the same questionnaire.

RESULTS

Postoperatively the EF and SD domains deteriorated significantly in both groups, but in a small proportion of the patients submitted to ileal neobladder they gradually improved with time (P = 0.006). At 12-month postoperative period, 4 (9.8 %) and 14 (35.0 %) patients in ileal conduit and ileal neobladder groups were able to achieve erections hard enough for vaginal penetration and maintained their erection to completion of intercourse, respectively (P = 0.006). Among patients in the ileal conduit and ileal neobladder groups, additional 4 (9.8 %) and 7 (17.1 %) patients were able to get some erection, but were unable to maintain their erection to completion of intercourse (P = 0.02). At 12-month follow up period 24.4 % of the ileal conduit and 45.0 % of the ileal neobladder patients rated their sexual desire very high or high (P = 0.01).

CONCLUSION

When performed properly, orthotopic ileal neobladder substitution after RCP offers better long-term results in terms of EF and SD.

The Studer orthotopic neobladder: long-term (more than 10 years) functional outcomes, urodynamic features, and complications

PURPOSE

Radical cystectomy and urinary diversion are the standard treatment for invasive bladder cancer. We analyzed the long-term (>10 years postoperatively) functional outcomes, complications, and urodynamic findings in a single center series of patients who underwent cystectomy and a Studer ileal neobladder substitution.

MATERIALS AND METHODS

A retrospective chart review of 108 Studer pouches constructed during 1990 and 2011 was performed. Data were analyzed in terms of long-term (>10 years) outcomes. Complications, incontinence, voiding difficulties, upper urinary tract changes, overall satisfaction, and urodynamic findings of the reservoir were obtained.

RESULTS

We evaluated 19 out of 50 patients who had lived for over 10 years postoperatively. Another 31 patients were not traced: 7 patients died following recurrence, 15 died due to exacerbation of a comorbidity, and 9 patients were lost to follow-up. Concerning complications, 6 patients had an atrophied kidney, 5 patients had moderate hydronephrosis, 5 patients had chronic recurrence of pylelonephritis, and 2 patients had voiding difficulty because of bladder neck stricture due to clean intermittent catheterization. One patient underwent an operation due to intestinal obstruction. Seven patients had incontinence; all 7 patients showed intermittently at night and 2 patients even in waking hours. Maximum bladder capacity was 484.1±119.2 mL, maximum flow rate was 13.6±9.7 mL/sec, and post-void residual urine volume was 146.8±82.7 mL.

CONCLUSION

Long-term outcomes with the Studer orthotopic ileal neobladder have an acceptable complication rate and good functional results. However, potential adverse outcomes such as renal deterioration, dysfunctional voiding should also be considered.

Definition, incidence, risk factors, and prevention of paralytic ileus following radical cystectomy: a systematic review

CONTEXT

Postoperative paralytic ileus (POI) has profound clinical consequences because it represents a substantial burden on both patients and health care resources.

OBJECTIVE

To determine the knowledge base regarding POI in the radical cystectomy (RC) population with an emphasis on preventive measures and risk factors.

EVIDENCE ACQUISITION

A systematic literature search of Medline (1966 to February 2011) and a study review were conducted. Eligible studies explicitly reported the incidence of POI and/or at least two quantitative measures of gastrointestinal recovery.

EVIDENCE SYNTHESIS

The search identified 727 relevant articles; 77 met eligibility criteria, comprising 13 793 patients. Of these, 21 used explicit definitions of POI, and they varied widely. Across studies, the incidence of POI ranged from 1.58% to 23.5%. Possible risk factors for POI included increasing age and body mass index. Seventeen studies reported effects of an intervention on POI: 3 randomized controlled studies, 11 observational cohort studies with concurrent comparison, and 3 observational cohort studies with nonconcurrent comparison. Gum chewing was associated with shortened times to flatus (2.4 vs 2.9 d; p<0.0001) and bowel movement (BM) (3.2 vs 3.9 d; p<0.001) in one observational cohort study (n=102); omission of a postoperative nasogastric tube (NGT) was associated with shorter time to flatus (4.21 vs 5.33 d; p=0.0001) and shorter length of stay (14.4 vs 19.1 d; p=0.001) in one observational cohort study (n=430); and the routine use of bowel preparation was associated with an increased incidence of POI (5% vs 19%) in another series (n=86). Additionally, readaptation of the dorsolateral peritoneal layer was shown to shorten times to flatus (p=0.016) and times to BM (p=0.011) in one randomized controlled study (n=200).

CONCLUSIONS

The incidence/definition of POI after RC is highly variable. An improved reporting strategy is needed to identify true incidence and risk factors, and to guide future research for both potential preventive and therapeutic interventions.

Morbidity and Quality of Life in Bladder Cancer Patients following Cystectomy and Urinary Diversion: A Single-Institution Comparison of Ileal Conduit versus Orthotopic Neobladder

Objective. To evaluate and compare noncontinent and continent urinary diversion after radical cystectomy in patients with bladder cancer. Methods. A total of 301 patients submitted to radical cystectomy at the Charité-University Hospital Berlin from 1993 to 2007 including 146 with an ileal conduit and 115 with an ileal neobladder. Clinical and pathological data as well as oncological outcome were retrospectively analyzed and compared. Quality of life was analyzed using the EORTC QLQ-C30 and BLM30 questionnaires. Results. 69.1% and 69.6% of all patients who received an ileal conduit and ileal neobladder, respectively, developed early complications. The two groups differed significantly concerning the occurrence of postoperative ileus (P = 0.02) favoring patients who received an ileal conduit but not with regard to any other early-onset complication evaluated. Patients with ileal neobladder had a significantly better global health status and quality of life (P = 0.02), better physical functioning (P = 0.02), but also a higher rate of diarrhoea (P = 0.004). Conclusion. Cystectomy with any type of diversion remains a complication-prone surgery. Even if the patient groups are not homogeneous in all respects, there are many arguments in favor of the ileal neobladder as the urinary diversion of choice.

Update on the management of non-muscle invasive bladder cancer

Non-muscle invasive bladder cancer (NMIBC) is a heterogeneous population of tumours accounting for 80% of bladder cancers. Over the years, the management of this disease has been changing with improvements in results and outcomes. In this review, we focus on the latest updates on the management of NMIBC.

[Total cystectomies for cancers locally advanced of bladder about 12 cases in the service of urology of the general hospital of Grand-Yoff]

OBJECTIVE

The goals of the study is to evaluate the feasability of the total cystectomy for cancer infiltrating locally advanced of bladder and to evaluate perioperatitive morbidity and short-term results.

PATIENTS AND METHODS

We made a retrospective study concerning 12 first patients having profited from a total cystectomy for cancer infiltrating of the bladder in our hospital over one period of 1 year. The parameters of study were: the age at the time of the diagnosis, circumstances of the diagnosis, antecedents of the patient, the histological type and stage TNM before and after intervention, the type of derivation associated, duration of the intervention, the anesthesia, complications and morbidity per- and postoperational. We carried out calculations of average and frequency for the data analysis.

RESULTS

The mean age was 51 years (extreme: 32; 83). They were nine men and three women. The circumstances of diagnosis were dominated by the total hematuria and in less frequency by the bladder irritative symptoms. The antecedents of the patients were dominated by the schistosomia (five cases) and the tobacco addiction (two cases). The histological type obtained in preoperative after biopsy or trans urethral resection of bladder found, seven cases of squamous cell carcinoma, four cases of transitional cell carcinoma and one case of adenocarcinoma. Into preoperative, three patients were at the stage pT2, eight patients pT3, one pT4. Four patients had a replacement of bladder: three by a bladder in Z and a patient had Camey II. They were the three patients pT2 preoperative and a patient pT3. Two patients had a standard ureterosigmoidostomy type coffey: the patient pT4 and a patient pT3. The six other patients had Bricker. All the patients profited from a blood transfusion peroperational (two units on average). We did not record any operational mortality. The complications and morbidity are represented by the suppurations of wall (three cases), the vesicocutaneous fistula (one case), the infections urinary and the anemia which was constant.

CONCLUSION

The management of bladder cancer poses a real problem in our countries because of the diagnosis at advanced stage.

Urinary diversion and morbidity after radical cystectomy for bladder cancer

BACKGROUND

The rate of continent urinary diversion after radical cystectomy for bladder cancer varies by patient and provider characteristics. Demonstration of equivalent complication rates, independent of diversion type, may decrease provider reluctance to perform continent reconstructions. The authors sought to determine whether continent reconstructions confer increased complication rates after radical cystectomy.

METHODS

From the Nationwide Inpatient Sample, the authors used International Classification of Disease (ICD-9) codes to identify subjects who underwent radical cystectomy for bladder cancer during 2001-2005. They determined acute postoperative medical and surgical complications from ICD-9 codes and compared complication rates by reconstruction type using the nearest neighbor propensity score matching method and multivariate logistic regression models.

RESULTS

Adjusting for case-mix differences between reconstructive groups, continent diversions conferred a lower risk of medical, surgical, and disposition-related complications that was statistically significant for bowel (3.1% lower risk; 95% confidence interval [95% CI], -6.8% to -0.1%), urinary (1.2% lower risk; 95% CI, -2.3%, to -0.4%), and other surgical complications (3.0% lower risk; 95% CI, -6.2% to -0.4%), and discharge other than home (8.2% lower risk; 95% CI, -12.1% to -4.6%) compared with ileal conduit subjects. Older age and certain comorbid conditions, including congestive heart failure and preoperative weight loss, were associated with significantly increased odds of postoperative medical and surgical complications in all subjects.

CONCLUSIONS

Mode of urinary diversion after radical cystectomy for bladder cancer is not associated with increased risk of immediate postoperative complications. These results may encourage broader consideration of continent urinary diversion without concern for increased complication rates.

Bladder cancer in the elderly

INTRODUCTION

Age is now widely accepted as the greatest single risk factor for developing bladder cancer, and bladder cancer is considered as primarily a disease of the elderly. Because of the close link between age and incidence of bladder cancer, it can be expected that this disease will become an enormous challenge with the growth of an aging population in the years ahead.

METHODS

Using MEDLINE, a search of the literature between January 1966 and July 2007 was performed to describe normative physiologic changes associated with aging, elucidate genetic and epigenetic alterations that associate aging with bladder cancer and its phenotypes; and to characterize how aging influences efficacies, risks, side effects, and potential complications of the treatments needed for the various stages of bladder cancer.

RESULTS

We discuss influence of aging on host physiology, genetic and epigenetic changes, environmental influences, and host factors in the development and treatment of bladder cancer. Treatments with intravesical bacille Calmette Guerin, radical cystectomy, and perioperative chemotherapy are less well tolerated and have poorer response in elderly patients compared with their younger counterparts. Elderly patients face both clinical and broader institutional barriers to appropriate treatment and may receive less aggressive treatment and sub-therapeutic dosing. However, when appropriately selected, elderly patients tolerate and respond well to cancer treatments.

CONCLUSIONS

The decision to undergo treatment for cancer is a tradeoff between loss of function and/or independence and extension of life, which is complicated by a host of concomitant issues such as comorbid medical conditions, functional declines and "frailty", family dynamics, and social and psychologic issues. Chronological age should not preclude definitive surgical therapy. It is imperative that healthcare practitioners and researchers from disparate disciplines collectively focus efforts towards gaining a better understanding of what the consequences of bladder cancer and its treatments are for older adults and how to appropriately meet the multifaceted medical and psychosocial needs of this growing population.

Radical cystectomy in the elderly patient: a contemporary comparison of perioperative complications in a single institution series

PURPOSE

To report on our recent experience with peri- and postoperative morbidity of radical cystectomy in patients 75 years and older compared to younger patients.

PATIENTS AND METHODS

Medical records of 326 consecutive patients undergoing radical cystectomy from May 2004 through April 2008 were reviewed.

RESULTS

Eighty-five of 326 patients (26%) were > or =75 years (75-95) old. ASA score was equal 3 or greater in 51% of patients > or =75 years and 32% of patients <75 years. Ileal conduit was performed in 83% of patients > or =75, 16% received an ileal neobladder compared to 46 and 51%, respectively, in patients <75. A total of 33 patients (39%) in the older patient group received blood transfusions intraoperatively compared to 76 patients (32%) in the younger age group. In 6 patients > or =75 years (7.1%) and 17 patients <75 (7.1%) open surgical revision was necessary, perioperative complication rate was 22 and 21%, respectively. The most common complications were wound dehiscence (5.9 vs. 7.5%), infections (4.7 vs. 4.6%), and pulmonary embolism (3.5 vs. 2.1%). Perioperative mortality was 1.2% (1 patient) in the elderly versus 0.4% (1 patient) in the younger age group.

CONCLUSION

Our data show that radical cystectomy can be offered to the elderly patient with acceptable morbidity. Because of higher comorbidity rate in the elderly, therapeutic decision for radical cystectomy in elderly patients should be made carefully and individually. Nevertheless our results demonstrate that age itself is not a main criterion which has to be considered strongly in decision making for radical cystectomy.

Bladder cancer

Bladder cancer is a heterogeneous disease, with 70% of patients presenting with superficial tumours, which tend to recur but are generally not life threatening, and 30% presenting as muscle-invasive disease associated with a high risk of death from distant metastases. The main presenting symptom of all bladder cancers is painless haematuria, and the diagnosis is established by urinary cytology and transurethral tumour resection. Intravesical treatment is used for carcinoma in situ and other high grade non-muscle-invasive tumours. The standard of care for muscle-invasive disease is radical cystoprostatectomy, and several types of urinary diversions are offered to patients, with quality of life as an important consideration. Bladder preservation with transurethral tumour resection, radiation, and chemotherapy can in some cases be equally curative. Several chemotherapeutic agents have proven to be useful as neoadjuvant or adjuvant treatment and in patients with metastatic disease. We discuss bladder preserving approaches, combination chemotherapy including new agents, targeted therapies, and advances in molecular biology.

Early vs Delayed Radical Cystectomy Compared in Highgrade Superficial Bladder Tumors

Objectives

The treatment of aggressive superficial TCC of the bladder remains controversial. In fact, although still classified as ‘superficial’, it has been shown that the biological characteristics of T1G3 bladder tumors are the same as those of the muscle-invasive group (T2 and above). Even with close monitoring and intensive intravesical therapy, the reported risk of muscle invasion in these patients is 53% and 1/3 die from this disease in the long-term. The aim of this study is to determine whether the timing of radical cystectomy affects the survival of patients with aggressive superficial bladder tumor.

Methods

We consider 74 patients who underwent radical cystectomy between November 1994 and October 2006 before a diagnosis of T1G3 bladder tumor. These patients were divided in 2 subgroups: group A (n=27, 25 M and 2 F) who underwent immediate radical cystectomy, and group B (n=47, 40 M and 7 F) who underwent other conservative treatments before radical cystectomy.

Results

The two subgroups were similar concerning age (66.29±8.37 yrs vs 66.87±8.6 yrs, respectively, p NS) and the timing of follow-up (respectively 77±45 vs 60±35 mths, p NS). Moreover, the progression-free survival was significantly higher in subgroup A (53.73±48.54 vs 31.94±35.19 mths, log-rank p<0.05) as well as the overall survival (59.73±45.37 vs 36.45±33.96 mths respectively, log-rank p<0.05). Comparing the histological examinations, the two subgroups were significantly different concerning the T stage (superficial tumors 14/27 vs 16/47, respectively, p<0.05; invasive tumors 13/27 vs 31/47, respectively, p<0.00005) and the lymphonodal dissemination (2N+/27 vs 11N+/47, respectively, p<<0.0005).

Conclusions

Delaying radical cystectomy for aggressive superficial bladder tumors leads to a worse progression-free survival; the overall survival is likely to be due also to an early lymphonodal dissemination, which occurs extending the timing between diagnosis and radical treatment.

Impact of stapling devices on radical cystectomy: comparative study between low- and high-volume surgeons

OBJECTIVES

To compare effectiveness in terms of blood loss and operative time of stapling devices among surgeons with different levels of surgical volume.

METHODS

We evaluated a group of 29 male patients with invasive bladder cancer who underwent radical cystectomy by two groups of surgeons. The first group included two high-volume surgeons, and the second group two low-volume surgeons. All cystectomies were performed using the multifire autosuture articulated vascular Endo-GIA. We compared patients with a series of 28 patients who had undergone radical cystectomy during the same period using standard technique by the same surgeons. Blood loss was defined as the difference between the hemoglobin at the beginning and at the end of cystectomy.

RESULTS

In the group of high-volume surgeons, the mean operative time was 81.4 +/- 17 minutes and 79.3 +/- 20 minutes for the classical and stapler arm, respectively (P = 0.551). In the low-volume surgeons group, the mean operative time was 114.3 +/- 22 minutes and 92.4 +/- 12 minutes for the two methods (P = 0.003). The mean intraoperative blood loss in the experienced surgeons was 2.3 +/- 0.82 g/dL and 1.49 +/- 0.66 g/dL for the classical and stapler arm, respectively (P = 0.008). In the group of low-volume surgeons, the difference in hemoglobin was 3.02 +/- 0.84 g/dL and 1.91 +/- 0.6 g/dL for the two methods (P = 0.02).

CONCLUSIONS

Stapling devices seem to make cystectomy safer and faster in surgeons with different surgical volumes. The group of low-volume surgeons benefited more.

Morbidity and quality of life in elderly patients receiving ileal conduit or orthotopic neobladder after radical cystectomy for invasive bladder cancer

OBJECTIVES

The objectives of the study were to evaluate morbidity, survival, and quality of life (QoL) in elderly patients with invasive bladder cancer who received an orthotopic neobladder or an ileal conduit.

METHODS

The charts of 85 patients, aged 75 or older (median age 78), who had received an ileal conduit (n = 53) or an orthotopic neobladder (n = 32) after radical cystectomy at 3 Italian institutions in the period January 2000 to September 2004 were retrospectively reviewed. Perioperative and postoperative complications were recorded, as well as survival data at last follow-up. QoL was evaluated in 34 of 37 patients who were alive at the time of analysis by using the European Organisation for Research and Treatment of Cancer (EORTC) instruments quality of life questionnaire C30 (QLQ-C30) and QLQ-muscle-invasive bladder cancer module (QLQ-BLM).

RESULTS

Multiple regression analysis showed that stage significantly affected survival whereas the type of urinary diversion did not. Global Health Status (GHS) scores in the neobladder group were higher than in the ileal conduit group but the difference was not statistically significant. The scores of all the QLQ multi-item scales and single-item measures were comparable in the 2 groups. Overall, 56% and 25% daytime and nighttime complete continence rates were observed in patients with an orthotopic neobladder.

CONCLUSIONS

The results of our retrospective analysis suggest that an orthotopic neobladder can be suitable for elderly patients with no additional morbidity compared with an ileal conduit. Both types of diversion seem to result in acceptable scores for most aspects of QoL, including urinary symptoms and continence rate. These figures may be helpful in the preoperative counselling of elderly patients with bladder cancer.

The management of superficial bladder cancer

From review of the currently available trial evidence, several clinical recommendations for bladder tumor management become apparent. Transurethral resection should be done, but this procedure is prone to both overestimating and underestimating staging. Restaging transurethral resection for patients with T1 tumors should, therefore, be performed. Data support the immediate postoperative instillation of a chemotherapeutic agent for patients with solitary, low-grade papillary tumors, whereas patients with multiple lesions might benefit from a more intensive adjuvant regimen. Although the use of intravesical immunotherapy for reducing tumor progression or as maintenance therapy is controversial, bacillus Calmette-Guérin has demonstrated significant benefit for tumor prophylaxis when no obvious residual disease is present. Early radical cystectomy can be beneficial and should be performed in patients with refractory T1 tumors or carcinoma in situ before progression to muscle invasion. In this Review I present an overview of the management of nonmuscle invasive bladder cancer. The most common intravesical chemotherapeutic agents are described as well as the impact of chemotherapy on the recurrence and progression of tumors. The effect of intravesical immunotherapy in bladder cancer is explored as well as the role of early cystectomy.

Urinary diversion: options, patient selection, and outcomes

Improved survival following radical cystectomy for bladder cancer as a result of advancements in combination chemotherapy and surgical technique has resulted in a philosophical change in the surgeon's approach to urinary diversion selection. Aims have evolved from the mere diversion of urine to a functional bowel conduit such as an ileal conduit or ureterosigmoidostomy, to providing the optimal diversion for the patient's quality of life. While quality of life is important, one must also consider the stage of cancer and individual patient comorbidities. Which diversion provides the best local cancer control, the lowest potential for complications (short and long term), and the easiest emotional adjustment in lifestyle while still allowing the timely completion of chemotherapy and therapeutic goals? A multidisciplinary approach to diversion selection that includes the patient, the medical oncologist, radiation oncologist, internist, and surgeon is ideal. We describe the three most commonly used types of diversions today, including conduits, continent cutaneous reservoirs, and orthotopic urethral diversions, as well as issues relative to patient selection and functional outcomes in patients undergoing radical cystectomy for the treatment of bladder cancer.

Radical cystectomy and lymphadenectomy for invasive bladder cancer: towards the evolution of an optimal surgical standard

The surgical management of invasive bladder cancer has undergone a significant evolution in technique since its initial introduction. Changes in the extent of surgery have largely reflected a better understanding of the natural history of bladder cancer and the recognized pathways of progression. Incorporation of contemporary surgical techniques that target the perivesical soft tissues, regional lymph nodes, and adjacent organs appear to enhance oncologic outcomes. A growing body of evidence indicates that the quality of radical cystectomy (RC) directly affects patient outcome. Recently, quality of life and functional considerations have led to surgical modifications such as nerve-, prostate-, vaginal wall-, and urethra-sparing approaches. While some modifications in appropriate candidates appear not to decrease cancer control, further studies will be needed to establish their role and safety. This ongoing evolution in the technique of RC and pelvic lymph node dissection (PLND) may help define a new surgical standard that provides optimal benefit in patients with invasive bladder cancer.

Evaluation of findings during re-exploration for obstructive ileus after radical cystectomy and ileal-loop urinary diversion: insight into potential technical improvements

OBJECTIVE

To retrospectively evaluate the findings during re-exploration for obstructive ileus after radical cystectomy (RC) and ileal conduit diversion.

PATIENTS AND METHODS

During a 12-year period, 434 patients who had RC and ileal conduit diversion were retrospectively evaluated for the diagnosis of early (</=30 days after RC) or late abdominal re-exploration. The operative reports of patients requiring a second abdominal procedure were reviewed, evaluating in particular the reason for small bowel obstruction (SBO). In addition, the type of entero-enteric anastomosis and the retroperitonealization of the uretero-enteric anastomosis were compared between patients who required abdominal re-exploration for SBO and those who did not.

RESULTS

Abdominal re-exploration for SBO was necessary for 14 (3.2%) and 32 (7.3%) patients in the early and late postoperative period, respectively. The most common reasons for SBO were anastomotic malfunction (1.4%) and malignant recurrence (2.8%). Adhesions were the second most common cause leading to ileus in both periods (1.1% and 2.3%, respectively). When there was no retroperitonealization of the uretero-enteric anastomosis, SBO occurred more often both early and late (P = 0.06). Early anastomotic malfunction leading to SBO was more common (but not statistically significant, P = 0.06) when the entero-enteric anastomosis was hand-sutured end-to-end.

CONCLUSIONS

Anastomotic malfunction, bowel adhesions and internal hernias are responsible for SBO early after surgery. The above reasons, in addition to malignant recurrence, are the most common reasons for SBO in the late postoperative period.
