Prognostic Features for Objectively Defined Urinary Continence after Radical Cystectomy and Ileal Orthotopic Neobladder in a Contemporary Cohort

A Novel Scoring System to Assess Continence Quality Outcomes of Orthotopic Ileal Neobladders After Open and Robot-Assisted Radical Cystectomy: The Urodynamic Trifecta

INTRODUCTION

A comprehensive scoring system for standardizing quality of functional outcomes of orthotopic ileal neobladders (OINs) is still unavailable. In this study we propose a novel trifecta for both open and robot-assisted radical cystectomy conceived on urodynamic parameters that summarize OINs functional outcomes regardless of the surgical technique used and predicts continence status.

MATERIALS & METHODS

Between June 2017 and May 2023 two prospective, institutional review board approved, radical cystectomy datasets were matched and queried for "OINs" "and "urodynamic evaluation" (n = 149). Urodynamic assessment was performed between 6 and 9 months after surgery. Baseline data and complete urodynamic profile including uroflowmetry, cystometry, compliance, presence of residual peristaltic activity, abdominal leak point pressures (ALPP) and daytime and night-time continence were reported. Descriptive analyses were used. Frequencies and proportions were reported for categorical variables while medians and interquartile ranges (IQRs) were reported for continuously coded variables. Trifecta was defined as the coexistence of: cystometric capacity ≥ 250 cc; neobladder compliance ≥ 35 cmH20; negative Valsalva and abdominal leak point pressure testing. Simultaneous achievement of only two of the presented criteria was considered a suboptimal result. Logistic regression analyses were built to identify predictors of daytime and night-time urinary continence. For all analyses, a two-sided p < 0.05 was considered significant.

RESULTS

Overall, at a median follow-up of 25 months (IQR 16-37), 149 patients achieved a complete urodynamic evaluation. In the current series, the complete trifecta rate was 40.2% while a suboptimal trifecta achievement was observed in 35.6% of patients. On multivariable analysis, complete trifecta achievement was the only independent predictor of daytime (OR 7.29, 95% CI 2.05-25.9) and night-time (OR 8.13; 95% CI 2.94-22.4) urinary continence, respectively (each p < 0.003). A complete UDM-T at urodynamic testing was associated with a day-time continence, night-time continence, and complete dry status rates of 93.2%, 83.1%, and 79.7%, respectively.

CONCLUSION

This novel urodynamic trifecta for OINs is based on standardized parameters and seems to be predictor of either daytime or night-time urinary continence at a midterm follow-up. Satisfactory continence outcomes may be also expected when a suboptimal trifecta rate is achieved.

Urinary diversion and quality of life: A six-year follow-up study of bladder cancer surgery

OBJECTIVES

To evaluate health-related quality of life (HRQOL) six years post-radical cystectomy in patients with muscle-invasive bladder cancer, comparing orthotopic ileal neobladder (ONB) and ileal conduit (IC). Therefore, the study aims to analyze the under-investigated long-term impact of standard bladder cancer treatments on HRQOL and provide insights into the HRQOL differences associated with these two common urinary diversion methods.

PATIENTS AND METHODS

This prospective study included 39 patients with urothelial carcinoma treated with ONB or IC at our center between 03/2013 and 01/2023. Patients with variant histology, metastasis, neoadjuvant chemotherapy, or benign indications for cystectomy were excluded. HRQOL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire preoperatively, at four and six years postoperatively. Statistical analyses included Chi-square tests, T-tests, and logistic regression models.

RESULTS

Of the patients, 64% (25/39) underwent ONB, and 76.9% (30/39) were male, with an average age of 69 years. No significant differences in overall good HRQOL (GHS > 70) were observed between ONB and IC at six years (IC: 60 ± 22; ONB: 69 ± 23, p = 0.2). Patients with IC reported higher insomnia at both follow-ups (4 years: p = 0.01; 6 years: p = 0.03). Emotional function remained stable in ONB patients but declined in IC patients from the fourth to sixth years (p = 0.04).

CONCLUSION

Long-term HRQOL did not significantly differ between ONB and IC up to six years post-radical cystectomy. Both urinary diversion methods can be offered to patients, with tailored discussions in terms of HRQOL.

Perioperative outcomes and continence following robotic-assisted radical cystectomy with mainz pouch II urinary diversion in patients with bladder cancer

PURPOSE

To present the widely unknown perioperative outcomes and continence status of bladder cancer patients following robotic-assisted radical cystectomy (RARC) with Mainz pouch II urinary diversion (UD).

MATERIALS AND METHODS

From November 2020 to December 2023, 37 bladder cancer patients who underwent RARC with Mainz pouch II UD were retrospectively assessed (ChiCTR2300070279). The results, which included patient demographics, perioperative data, continence, and complications (early ≤ 30 days and late ≤ 30 days) were reported using the RC-pentafecta criteria. RC-pentafecta criteria included ≥ 16 lymph nodes removed, negative soft tissue surgical margins, absence of major (Grade III-IV) complication at 90 days, absence of clinical recurrence at ≤ 12 months, and absence of long-term UD-related sequelae. A numeric rating scale assessed patient satisfaction with urinary continence 30 days after surgery. The validated Patient Assessment of Constipation Symptoms (PAC-SYM) questionnaire was used to evaluate bowel function. The Kaplan-Meier curve was used to evaluate overall survival (OS).

RESULTS

Of the 37 patients evaluated over a median (range) follow-up period of 23.0 (12.0-36.5) months. The median (range) age was 65 (40-81) years. The median (range) time to urinary continence after surgery was 2.3 (1.5-6) months. Of the 37 patients, 31 (83.8%) were continent both during the day and at night, 34 (91.9%) were continent during the day, 32 (86.5%) were continent at night, 35 (94.6%) were satisfied with their urinary continence status, and 21 (56.8%) were very satisfied. The mean (range) voiding frequency was 6 (4-10) during the day and 3 (2-5.5) at night. The mean (range) PAC-SYM total score was 9.50 (4.00-15.00). In 12 (32.4%) of the patients, RC-pentafecta was achieved, and achieving RC-pentafecta was linked to better satisfaction scores (7.3 vs. 5.5, p = 0.034). There was no significant difference between RC-pentafecta and No RC-pentafecta groups in terms of OS (25.6 vs. 21.5 months, p = 0.16). 7 (19.4%) patients experienced late complications.

CONCLUSIONS

Mainz pouch II UD following RARC in bladder cancer patients results in a satisfactory continence rate. Achieving RC-pentafecta was correlated with better satisfaction scores. The intracorporeal approach to Mainz pouch II UD is beneficial for female patients due to its reduced invasiveness.

Development and evaluation of a rehabilitation training compliance scale for patients with urinary incontinence

BACKGROUND

Urinary incontinence treatment includes conservative treatment, physical devices, medication, and surgery. Pelvic floor muscle training combined with bladder training is among the most effective, non-invasive, and economical ways to treat urinary incontinence, and compliance with training is essential in urinary incontinence treatment. Several instruments assess pelvic floor muscle training and bladder training. However, no tool has been found that assesses compliance with pelvic floor muscle training when combined with bladder training for urinary incontinence. This study aimed to develop a rehabilitation training compliance scale for patients with urinary incontinence and to evaluate its validity and reliability.

METHODS

This study was performed in two tertiary hospitals in Hainan, China between December 2020 and July 2021, 123 patients were included. A literature review, group discussions, and two rounds of letter consultations were performed to acquire the item pool and finalise the 12 items for this scale. Exploratory and confirmatory factor analysis, Cronbach's α, split-half reliability, test-retest reliability, content validity, construct validity, convergent and discriminant validity, and criterion-related validity were used to examine the items in the scale.

RESULTS

A 12-item scale comprising three factors accounted for 85.99% of the variance in the data. The Cronbach's α, split-half reliability, test-retest reliability, and content validity index of the scale were 0.95, 0.89, 0.86, and 0.93, respectively. Comparison with the Chen pelvic floor muscle exercise self-efficacy scale showed high calibration correlation validity (coefficient = 0.89).

CONCLUSIONS

The training compliance scale developed in this study is a valid and reliable measurement tool to assess pelvic floor muscle training and bladder training compliance in patients with urinary incontinence.

Impact of early self-clean intermittent catheterization in orthotopic ileal neobladder: prospective randomized study to evaluate functional outcomes, continence status and urinary tract infections

BACKGROUND

Urinary diversions after radical cystectomy (RC) have a significant impact on quality of life and body image. Particularly for orthotopic neobladder (ONB), the rate of continence, urinary retention and urinary tract infections can impact on patient's quality of life. The aim of this study was to investigate whether early clean intermittent catheterization (CIC) might improve functional outcomes, continence status, and reduce the incidence of UTIs in patients with ONB.

METHODS

In this prospective randomized study patients were divided in two groups. Patients were on a standard postoperative care (group A) or started CIC within the first postoperative month (group B). All patients were evaluated postoperatively at 1, 3, 6, and 9 months after ONB. The CIC was executed 4 times/daily after each voluntary micturition. The postoperative evaluation included: post-void residual volume (PVR), urine analysis and culture, number of pads/day and the self-administrated questionnaire International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF).

RESULTS

Thirty-nine male and 8 female patients underwent laparoscopic or robotic RC with intracorporeal ONB (37 U shaped and 10 Padua reconstructions). At the first follow up, mean PVR was in group A and B, 136.5 mL and 125.7 mL (P value: 0.105), respectively. The ICIQ-UI SF mean score was 16.2 and 17.1 (P value: 0.243) respectively and the mean no. of pads/day was 3 in both groups. 15 patients in group A and 10 in group B reported episodes of symptomatic UTIs. At 3, 6 and 9 months follow up after surgery the PVR and the ICIQ-UI SF scores were significantly improved (P value <0.0001). The number of pads decreased to 2 pads/day in group A and 1 in group B at 9 months. The episodes of UTIs significantly decreased over the time (P value <0.0001).

CONCLUSIONS

Our data support the early introduction of self CIC in patients with ONB after RC. The CIC was significantly associated a reduced risk of incontinence, urinary retention, and UTI with significant improvement in QoL. These encouraging data need to be confirmed by further investigations with a larger number of patients.

Evaluation of Bowel Function Following Radical Cystectomy and Urinary Diversion Using Two Validated Questionnaires: What Are the Effects on Quality of Life?

OBJECTIVE

To assess both short- and long-term constipation symptoms and their impact on quality of life in patients who underwent radical cystectomy (RC) with three different types of urinary diversion: orthotopic neobladder (ONB), continent cutaneous diversion (CCD), and ileal conduit (IC).

MATERIALS AND METHODS

The validated Patient Assessment of Constipation Symptoms (PAC-SYM) and Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaires were administered to all patients at follow-up greater than 30 days from surgery. Clinical and pathological characteristics were prospectively recorded in an institutional review board approved bladder cancer database. Using multivariable linear regression analyses, we determined significant predictors of improved constipation symptoms and quality of life scores.

RESULTS

A total of 198 patients completed 255 PAC-SYM and PAC-QOL questionnaires with a median follow-up time of 1.7 years (IQR: 0.7 - 3.0 years). ONB, CCD, and IC were performed in 78%, 5.5%, and 16.5% of patients, respectively. Higher bowel function scores (i.e. worse symptoms) were noted at 3 months post-operatively, while these scores significantly improved over time for PAC-SYM total score (P = .004), abdominal subscore (P = .001), and rectal subscore (P = .018). On multivariable analysis, we found that patients <70 years old (B -2.1, P = .004), with follow-up >1 year (B -4.8, P = .001), and who received an IC (B -2.4, P = .02) had significantly lower PAC-SYM scores.

CONCLUSION

Patients have few constipation symptoms and are overall satisfied with their bowel function at long-term follow-up after RC. While patients with IC have significantly fewer constipation symptoms compared to those with ONB or CCD, all patients had significant improvement one year after the surgery.

Ileal conduit or orthotopic neobladder: selection and contemporary patterns of use

PURPOSE OF REVIEW

The orthotopic neobladder and ileal conduit are the two most commonly utilized urinary diversions among patients undergoing radical cystectomy. Although orthotopic diversion offers several advantages, only 20% of patients nationally receive this diversion, with decreasing utilization over time. The purpose of this article is to review advantages of each diversion type and considerations in patient selection, review trends in diversion utilization and perioperative and functional outcomes, and examine recent studies evaluating methods of optimizing diversion selection and patient satisfaction and outcomes.

RECENT FINDINGS

Decreasing utilization of orthotopic diversion has coincided with the increasing utilization of minimally invasive surgical techniques. A multicentre robotic series demonstrated a higher incidence of high-grade complications with intracorporeal diversion, reflecting the learning-curve associated with this technique. Patient satisfaction with urinary diversion is associated with informed decision-making and goal alignment. Ongoing quality of life studies is aiming to identify predictors of patient satisfaction with the selected urinary diversion and may help guide patient counselling.

SUMMARY

Given the potential advantages of orthotopic diversion, its decreasing use is a concerning trend. Elucidating patient goals and informed decision-making are critical to patient satisfaction. A patient-centred approach should be used when selecting the type of urinary diversion for a given patient.

Orthotopic Neobladder Reconstruction: Patient Selection And Perspectives

Orthotopic neobladder (ONB) reconstruction is a continent urinary diversion procedure that may be performed in a patient with bladder cancer following a radical cystectomy. The selection of a patient for an ONB reconstruction is strict as not everyone may be suitable to undergo this complex surgery. Patients must be not only mentally competent but also physically dexterous enough to allow for appropriate neobladder training post-procedure, to achieve best urinary function. However, even with a carefully chosen patient population, various complications specific to ONB reconstruction may result. Metabolic acidosis may result from electrolyte shifts, resulting in secondary complications such as bone demineralization and urinary calculi. In addition, nutritional deficiencies may result from the use of a transposed intestinal segment for the fashioning of the reservoir. A widely used outcome measure when assessing for ONB reconstruction is continence. With a strict neobladder training regimen, daytime continence may be achieved in roughly 70% of patients post-ONB procedure. This number may increase over the course of several years, although may decrease in up to 20 years of follow-up. Similarly, quality of life (QoL) measures have been widely studied, and current literature suggests slightly better QoL achieved with ONB compared to other urinary diversion procedures. Of note, the tools used to assess continence and QoL vary between studies, limiting the interpretability of the summarized data. Nevertheless, ONB reconstruction is a procedure that is still evolving, with ongoing modifications that can reduce complications and improve patient urinary function.

Long-Term Follow-Up and Oncological Outcome of Patients Undergoing Radical Cystectomy for Bladder Cancer following an Enhanced Recovery after Surgery (ERAS) Protocol: Results of a Large Randomized, Prospective, Single-Center Study

INTRODUCTION

Enhanced recovery after surgery (ERAS) concepts are implemented in various surgical disciplines. For patients undergoing radical cystectomy, prospective data are still rare. In the year 2014, our group could prove significant benefits of ERAS for these patients in a prospective randomized study compared to a conservative regimen.

OBJECTIVE

To evaluate long-term follow-up results of ERAS concepts in patients undergoing radical cystectomy for bladder cancer.

METHODS

Of the 101 patients who had initially prospectively been randomized to ERAS or a conservative regimen, 35 patients could be included in the study. Median follow-up time was 83 months. Primary end point assessed quality of life. Secondary end points were cancer-specific survival and overall survival.

RESULTS

Five to seven years after the initial inclusion to the study, no significant difference regarding quality of life parameters was detected (p values range between 0.112 and 0.970). Continence status in patients with neobladder showed no significant differences between ERAS and conservative regimens (p = 0.785). Cancer-specific survival in the ERAS group did not differ significantly from that in the conservative group (49 vs. 58%, p = 0.725).

CONCLUSIONS

While ERAS represents an excellent way to improve postoperative reconvalescence and quality of life in the short-term follow-up, our data do not support the idea that there is also a long-term effect in terms of quality of life issues.

Cluster analysis identifies three urodynamic patterns in patients with orthotopic neobladder reconstruction

PURPOSE

To classify patients with orthotopic neobladder based on urodynamic parameters using cluster analysis and to characterize the voiding function of each group.

MATERIALS AND METHODS

From January 2012 to November 2015, 142 patients with bladder cancer underwent radical cystectomy and Studer neobladder reconstruction at our institute. Of the 142 patients, 103 with complete urodynamic data and information on urinary functional outcomes were included in this study. K-means clustering was performed with urodynamic parameters which included maximal cystometric capacity, residual volume, maximal flow rate, compliance, and detrusor pressure at maximum flow rate. Three groups emerged by cluster analysis. Urodynamic parameters and urinary function outcomes were compared between three groups.

RESULTS

Group 1 (n = 44) had ideal urodynamic parameters with a mean maximal bladder capacity of 513.3 ml and mean residual urine volume of 33.1 ml. Group 2 (n = 42) was characterized by small bladder capacity with low compliance. Patients in group 2 had higher rates of daytime incontinence and nighttime incontinence than patients in group 1. Group 3 (n = 17) was characterized by large residual urine volume with high compliance. When we examined gender differences in urodynamics and functional outcomes, residual urine volume and the rate of daytime incontinence were only marginally significant. However, females were significantly more likely to belong to group 2 or 3 (P = 0.003). In multivariate analysis to identify factors associated with group 1 which has the most ideal urodynamic pattern, age (OR 0.95, P = 0.017) and male gender (OR 7.57, P = 0.003) were identified as significant factors.

CONCLUSIONS

While patients with ileal neobladder present with various voiding symptoms, three urodynamic patterns were identified by cluster analysis. Approximately half of patients had ideal urodynamic parameters. The other two groups were characterized by large residual urine and small capacity bladder with low compliance. Young age and male gender appear to have a favorable impact on urodynamic and voiding outcomes in patients undergoing orthotopic neobladder reconstruction.

Prospective evaluation of health-related quality of life after radical cystectomy: focus on peri- and postoperative complications

OBJECTIVES

To analyse the impact of perioperative complications and complex treatment courses on postoperative health-related quality of life (HRQOL) after radical cystectomy (RC) and continent (ONB) or incontinent (IC) urinary diversion at multiple prospective time points.

METHODS

A total of 121 consecutive patients underwent RC with curative intent between 2013 and 2014. HRQOL was prospectively assessed preoperatively, after 3 and 12 months, using the QLQ-C30 questionnaire. The impact of complex perioperative treatment courses including cases requiring surgical re-interventions was retrospectively assessed using Martin criteria and the Clavien-Dindo scale. Urinary continence was determined using the validated ICIQ-SF questionnaire. Statistical analysis included Kruskal-Wallis ANOVA, Spearman's rank correlation, and ordinal regression models (p < 0.05).

RESULTS

A total of 100 patients underwent further analysis. Physical functioning (PF), role functioning (RF), and global health status (GHS) scores were higher in the ONB subgroup both preoperatively (p < 0.001, 0.010, 0.048) and 3 months after RC (p = 0.003, 0.048, 0.019). Clavien complications ≥III led to reduced PF levels after 3 months (p = 0.050) without effect on GHS (p = 0.825). Operating time and length of critical care monitoring correlated with 3 months pain scores in the ONB subgroup (p = 0.003, 0.009) without affecting GHS (p = 0.603, 0.653). Continent urinary diversion was an independent predictor of increased HRQOL after 3 months (p = 0.021), however, not after 12 months (p = 0.803).

CONCLUSIONS

Patients receiving an IC have lower PF, RF, and GHS scores than those receiving ONB. Perioperative complications and complicated treatment courses can affect HRQOL subdomains but do not significantly impact the GHS. ONB is an independent predictor for better overall HRQOL 3 months, but not 12 months after RC.
