Comparison of readmission and short-term mortality rates between different types of urinary diversion in patients undergoing radical cystectomy

The Association between Urinary Diversion Type and Other-Cause Mortality in Radical Cystectomy Patients

BACKGROUND

It is unknown whether more complex UD, such as orthotopic neobladder and abdominal pouch, may be associated with higher OCM rates than ileal conduit. We addressed this knowledge gap within the SEER database 2004-2020.

METHODS

All T1-T4aN0M0 radical cystectomy (RC) patients were identified. After 1:1 propensity score matching (PSM), cumulative incidence plots, univariable and multivariable competing-risks regression (CRR) models were used to test differences in OCM rates according to UD type (orthotopic neobladder vs. abdominal pouch vs. ileal conduit).

RESULTS

Of all 3008 RC patients, 2380 (79%) underwent ileal conduit vs. 628 (21%) who underwent continent UD (268 orthotopic neobladder and 360 abdominal pouch). After PSM relative to ileal conduit, neither continent UD (13 vs. 15%; p = 0.1) nor orthotopic neobladder (13 vs. 16%; p = 0.4) nor abdominal pouch (13 vs. 15%; p = 0.2) were associated with higher 10-year OCM rates. After PSM and after adjustment for cancer-specific mortality (CSM), as well as after multivariable adjustments relative to ileal conduit, neither continent UD (Hazard Ratio [HR]:0.73; p = 0.1), nor orthotopic neobladder (HR:0.84; p = 0.5) nor abdominal pouch (HR:0.77; p = 0.2) were associated with higher OCM.

CONCLUSIONS

It appears that more complex UD types, such as orthotopic neobladder and abdominal pouch are not associated with higher OCM relative to ileal conduit.

Hybrid ileal pouch with concomitant anti-refluxing and refluxing ureteroileal anastomosis

PURPOSE

We report our preliminary experience of using a hybrid ileal pouch, assessing oncologic outcomes, complications, voiding, and renal function.

METHODS

The study included 25 patients with bladder cancer treated with radical cystectomy with a hybrid ileal pouch with concomitant anti-refluxing and refluxing anastomosis, performed by a single surgeon. The patients were divided into two groups (first and last cases) according to the surgery date. Postoperative complications, separate renal function by renal scan, voiding function by uroflowmetry with residual urine, and oncologic outcomes were assessed.

RESULTS

The surgery duration was shorter in the last cases than the first cases. The voiding volume increased with time. There were 23 cases of grade 3 complication in 12 patients and one case of grade 4 complication (sepsis). In the first cases, ureterovesical stenosis occurred in five cases, whereas in the last cases, there were no cases of stenosis. In separate renal function, there was no difference between the left and right side or between the first and last cases.

CONCLUSIONS

The hybrid ileal pouch showed acceptable oncologic and functional outcomes and complications; therefore, it can be used according to the appropriate surgical situation with a relatively short bowel segment during neobladder construction.

Miami Pouch: A Simple Technique for Efficient Continent Cutaneous Urinary Diversion

OBJECTIVE

To report a contemporary series of Miami pouch (MP) enriched with a full technical description and step-by-step video to contribute to wider use.

PATIENTS AND METHODS

A retrospective charts review of all patients who had a MP at our center between January 2016 and December 2017 was performed. The MP technique uses the terminal 15cm of ileum and the right colon to build an intestinal heterotopic pouch located in the right iliac fossa and connected to the skin by an efferent catheterizable tube. Primary outcome was continence defined as the absence of leakage between clean intermittent self-catheterization (CISC) with a maximal interval of 4 hours between each CISC.

RESULTS

Fifteen patients had MP during the study period. Thirty-day postoperative Clavien III complications were observed in 2 (13.3%) patients. At 39 months of median follow-up, continence was obtained for all patients except for 2 patients whom reported intermittent night-time leakages due to long intervals (5 to 7 hours) between 2 CISC. No significant alteration of renal function was reported and no stenosis of the efferent tube neither difficulty to perform CISC was observed.

CONCLUSIONS

For patients who are candidates for radical cystectomy and not eligible for orthotopic neobladder, intestinal heterotopic pouch with a cutaneous continent urinary diversions as MP may be a reliable alternative. Patients should be informed of the existence of a valid alternative to ileal conduit since it may fit their expectations of a preserved body image without urine collecting appliances.

Comparison of survival in elderly patients treated with uretero-cutaneostomy or ileal conduit after radical cystectomy

Background

In bladder cancer patients with age ≥ 80 years old, there have been controversies in performing uretero-cutaneostomy or ileal conduit as urinary diversion after radical cystectomy. Limited study evaluated overall survival (OS) and cancer-specific survival (CSS) between the two urinary diversions in elderly patients. This study is to compare OS and CSS between uretero-cutaneostomy and ileal conduit after radical cystectomy in bladder cancer patients with age ≥ 80 years old.

Patients and methods

Data were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Bladder cancer patients diagnosed between 2004 and 2016 with age ≥ 80 years old who underwent radical cystectomy with either UC or IC were selected. After propensity score matching, Cox regression and Kaplan-Meier analysis were used to analyze the survival. We calculated statistical power for survival.

Results

Of 1394 patients who met the inclusion criteria, 1093 underwent ileal conduit and 301 underwent uretero-cutaneostomy. After propensity score matching, 285 patients were included in each group. Multivariable Cox analysis showed urinary diversion was not a risk factor of OS and CSS (HR 1.044, [95% CI 0.867–1.257] and 1.012 [0.748–1.368], respectively). Both OS and CSS were not significantly different, with median survival of ileal conduit and uretero-cutaneostomy were 19 [16–24] months and 19 [15–26] months respectively. Additionally, We found OS had the following risk factors: tumor stage (distant vs regional vs localized, 5.332 [3.610–7.875] vs 1.730 [1.375–2.176] vs 1), node density (>0.2 vs ≤0.2 vs none, 1.410 [1.047–1.898] vs 0.941 [0.658–1.344] vs 1) and age (1.067 [1.032–1.103] for each year). While CSS had the following risk factors: tumor stage (distant vs regional vs localized, 4.035 [2.046–7.959] vs 2.476 [1.651–3.713] vs 1), node density (>0.2 vs ≤0.2 vs none, 2.501 [1.645–3.804] vs 1.062 [0.590–1.914] vs 1) and tumor size (greater than 3 cm vs less than 3 cm, 1.596 [1.057–2.412] vs 1). Our analysis obtained 0.707 power for overall survival.

Conclusion

Urinary diversion by uretero-cutaneostomy or by ileal conduit was not associated with overall and cancer-specific survival. It is reasonable to consider uretero-cutaneostomy as a regular procedure of urinary diversion in elderly bladder cancer patients after radical cystectomy to avoid associate complications.

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.

Prognostic impact of preoperative renal function in patients treated with radical cystectomy: a multi-institutional retrospective study

BACKGROUND

Little data on the preoperative prognostic factors in radical cystectomy (RC) patients have made it difficult to choose the appropriate type of urothelial diversion (UD). This study aimed to investigate the prognostic role of UD, with a subgroup analysis of that of preoperative renal function.

METHODS

From 1990 to 2015, 279 patients underwent RC for bladder cancer at six hospitals affiliated with Kitasato University in Japan. All patients were divided into three groups: cutaneous ureterostomy (CU; n = 54), ileal conduit (IC; n = 139), and orthotopic neobladder (NB; n = 86). Patients were also stratified into three groups based on preoperative estimated glomerular filtration rate (eGFR) (mL/min/1.73 m²): normal eGFR (> 60 mL/min/1.73 m²; n = 149), moderately reduced eGFR (45-60 mL/min/1.73 m²; n = 66), and severely reduced eGFR (< 45 mL/min/1.73 m²; n = 37). Statistical analyses were performed to investigate prognostic values of UD and preoperative eGFR.

RESULTS

Kaplan-Meier analyses showed that progression-free survival (PFS) and cancer-specific survival (CSS) did not differ between the three types of UD groups. With regard to renal function, the preoperative severely reduced group had significantly worse PFS and CSS than the other groups. The multivariate analysis showed that severely reduced preoperative eGFR was an independent risk factor of worse PFS and worse CSS.

CONCLUSION

The present study demonstrated that preoperative severe renal function was shown as an independent risk factor of both PFS and CSS.

Comparison of postoperative complications and quality of life between patients undergoing continent versus non-continent urinary diversion after pelvic exenteration for gynecologic malignancies

BACKGROUND

Pelvic exenteration and its reconstructive techniques have been associated with high postoperative morbidity and a negative impact on patient quality of life. The aim of our study was to compare postoperative complications and quality of life in patients undergoing continent compared with non-continent urinary diversion after pelvic exenteration for gynecologic malignancies.

METHODS

We designed a multicenter study of patients from 10 centers who underwent an anterior or total pelvic exenteration with urinary reconstruction for histologically confirmed persistent or recurrent gynecologic malignancy after previous treatment with radiotherapy. From January 2005 to September 2008, we included patients retrospectively, and from September 2008 to May 2009, patients were included prospectively which allowed collection of quality of life data. Demographic, surgical, and follow-up data were analyzed. Postoperative complications were classified according to the Clavien-Dindo classification. Quality of life was assessed using the European Organization for Research and Treatment of Cancer (EORTC)-QLQ-C30 (V.3.0) and EORTC-QLQ-OV28 quality of life questionnaires. We compared patients who underwent a continent urinary diversion with those who underwent a non-continent reconstruction.

RESULTS

We included 148 patients, 92 retrospectively and 56 prospectively. Among them, 77.4% had recurrent disease and 22.6% persistent disease after the primary treatment. In 70 patients, a urinary continent diversion was performed, and 78 patients underwent a non-continent diversion. Median age of the continent and incontinent groups was 53.5 (range 33-78) years and 57 (26-79) years, respectively. There were no significant differences between the continent and non-continent groups in median length of hospitalization (28.5 vs 26 days, P=0.19), postoperative grade III-IV complications (42.9% vs 42.3%, P=0.95), complications needing surgical (27.9% vs 34.6%, P=0.39) or radiological (14.7% vs 12.8%, P=0.74) intervention, and complication type (digestive (23.2% vs 16.7%, P=0.32) and urinary (15.9% vs 16.7%, P=0.91)). There were no significant differences between the groups in global health, global quality of life, and body image perception scores 1 year after surgery.

CONCLUSION

Continent and incontinent urinary reconstructions are equivalent in terms of postoperative complications and quality of life scores.

Hospitalisation and readmission costs after radical cystectomy in a nationally representative sample: does urinary reconstruction matter?

OBJECTIVE

To investigate the impact of continent urinary diversion on readmissions and hospital costs in a nationally representative sample of radical cystectomies (RCs) performed in the USA.

PATIENTS AND METHODS

The 2010-2014 Nationwide Readmissions Database was queried for patients with a diagnosis of bladder cancer who underwent RC. We identified patients undergoing continent (neobladder or continent cutaneous reservoir) or incontinent (ileal conduit) diversions. Multivariable logistic regression models were used to identify predictors of 90-day readmission, prolonged length of stay, and total hospital costs.

RESULTS

Amongst 21 126 patients identified, 19 437 (92.0%) underwent incontinent diversion and 1 689 (8.0%) had a continent diversion created. Continent diversion patients were younger, healthier, and treated at high-volume metropolitan centres. Continent diversions resulted in fewer in-hospital complications (37.3% vs 42.5%, P = 0.02) but led to more 90-day readmissions (46.5% vs 39.6%, P = 0.004). In addition, continent diversion patients were more often readmitted for infectious complications (38.7% vs 29.4%, P = 0.004) and genitourinary complications (18.5% vs 13.0%, P = 0.01). On multivariable logistic regression, patients with a continent diversion were more likely to be readmitted within 90 days (odds ratio [OR] 1.55, 95% confidence interval [CI]: 1.28, 1.88) and have increased hospital costs during initial hospitalisation (OR 1.99, 95% CI: 1.52, 2.61). Continent diversion led to a $4 617 (American dollars) increase in initial hospital costs ($36 640 vs $32 023, P < 0.001), which was maintained at 30 days ($48 621 vs $44 231, P < 0.001) and at 90 days ($56 380 vs $52 820, P < 0.001).

CONCLUSION

In a nationally representative sample of RCs performed in the USA, continent urinary diversion led to more frequent readmissions and increased hospital costs. Interventions designed to address specific outpatient issues with continent diversions can potentially lead to a significant decrease in readmissions and associated hospital costs.
