Long-Term Voiding Pattern of Patients With Ileal Orthotopic Bladder Substitutes

Open vs robotic intracorporeal Padua ileal bladder: functional outcomes of a single-centre RCT

PURPOSE

Functional outcomes of robot-assisted (RA) radical cystectomy (RC) with intracorporeal orthotopic neobladder (i-ON) have been poorly investigated. The study aimed to report functional outcomes of a prospective randomized controlled trial (RCT) comparing open RC (ORC) and RARC with i-ON.

METHODS

Inclusion criteria were cT2-4/N0/M0, or BCG-failure high-grade urothelial carcinoma, candidate to RC with curative intent. A covariate adaptive randomization process was used, based on the following variables: BMI, ASA score, haemoglobin levels, cT-stage, neoadjuvant chemotherapy, urinary diversion. Day-time continence was defined as "totally dryness", nigh-time continence as pad wetness ≤ 50 cc. Continence recovery probabilities were compared between arms with Kaplan-Meier method and Cox regression analysis was performed to identify predictors of continence recovery. HRQoL outcomes analysis was assessed with a generalized linear mixed effect regression (GLMER) model.

RESULTS

Out of 116 patients randomized, 88 received ON. Quantitative analysis of functional outcomes reported similar results in terms of day continence, while a better night continence status in ORC cohort was observed. However, 1-yr day- and night-time continence recovery probabilities were comparable. Night-time micturition frequency < 3 h was the only predictor of nigh-time continence recovery. At GLMER, 1-yr body image and sexual functioning were significantly better in RARC cohort, while urinary symptoms were comparable between arms.

CONCLUSION

Despite superiority of ORC at quantitative night-time pad use analysis, we showed comparable day- and night-time continence recovery probabilities. At 1-yr analysis of HRQoL outcomes, urinary symptoms were comparable between arms, while RARC patients reported lower body image and sexual functioning worsening.

"Bordeaux Neobladder": First Evaluation of the Urodynamic Outcomes

Background

The intracorporeal orthotopic modified-Y "Bordeaux" neobladder (iYNB) was first described in 2016. No urodynamic evaluation of this neobladder has yet been performed.

Objective

To present the urodynamic features of the iYNB and incontinence-specific health-related quality of life (HRQoL) outcomes.

Design setting and participants

We prospectively assessed 26 patients operated between September 2018 and November 2020.

Surgical procedure

Robotic radical cystectomy for malignant disease of the bladder and iYNB, performed by a single surgeon, were used.

Measurements

Three months after surgery and in November 2021, consenting patients underwent clinical evaluation and multichannel urodynamic study (UDS). The incontinence quality of life (I-QoL) questionnaire was used to evaluate HRQoL. Continence was classified into day- and nighttime, and clinically defined as the use of zero pads. A descriptive statistical analysis was performed.

Results and limitations

The mean age at surgery was 65.4 yr. The mean follow-up period was 27 mo (12-38). The mean time for the neobladder reconstruction was 192 min (110-340). The mean maximum capacity was 431 cm3 (range 200-553). The mean postvoid residual was 101.6 ml (0-310), and the rate of clean intermittent catheterization was 17.6%. With the exception of a significant reduction in the volume of the first sensation of bladder fullness, no other statistically significant changes in the UDS parameters of both the storage and the voiding phase were observed over time. Day- and nighttime continence rates were 58.8% and 23.5%, respectively. The mean postoperative I-QoL score was 103.3 (89-110). Limitations include the small number of patients and short follow-up.

Conclusions

The UDS evaluation of iYNB demonstrates that both the volumetric and the pressure characteristics are acceptable and may enhance quality of life. Prospective studies with larger numbers of patients and longer follow-up are needed to further evaluate the iYNB.

Patient summary

The "Bordeaux" neobladder provides acceptable urodynamic outcomes. It is associated with high levels of health-related quality of life and good rates of continence in patients.

Neobladder "Function": Tips and Tricks for Surgery and Postoperative Management

Orthotopic neobladder (ONB) reconstruction is a continent urinary diversion procedure increasingly used in patients with muscle-invasive bladder cancer following radical cystectomy (RC). It represents a valid alternative to the ileal duct in suitable patients who do not prefer a stoma and are motivated to undergo adequate training of the neobladder. Careful patient selection, taking into account the absolute and relative contraindications for ONB as well as an adequate recovery protocol after surgery are integral to the success of this procedure and the oncological and functional outcomes. The objective of this review is to summarize the current data on RC with ONB in terms of patient selection, preoperative preparation, surgical techniques and functional (continence and sexual activity) and oncological outcomes, with particular attention to the management of complications and the impact on quality of life (QoL).

Round ligament suspending treatment in orthotopic ileal-neobladder after radical cystectomy in women: a single-centre prospective randomised trial

OBJECTIVES

To compare the occurrence of emptying dysfunction between surgical techniques for orthotopic neobladder suspended with round ligament (rONB) and the standard procedure (sONB).

PATIENTS AND METHODS

A prospective randomised controlled trial was performed in a single centre of female patients undergoing creation of an ONB using rONB or sONB. Patients were followed for ≥24 months after ONB. The primary endpoints were significant post-void residual urine volume (sPVR) and need for clean intermittent catheterisation (CIC) at 24 months postoperatively. The secondary endpoints included early and late complications, urodynamic profile, and ONB continence.

RESULTS

Between January 2011 and October 2017, the trial enrolled 85 patients, of whom 82 were randomised. A total of 41 patients had a rONB and 41 a sONB. At 24 months, 17 of the 37 patients with a sONB and nine of the 39 patients with a rONB had a sPVR. The cumulative risk of a sPVR was significantly lower in the rONB group (23.1%) vs the sONB group (45.9%) (hazard ratio [HR] 0.43, 95% confidence interval [CI], 0.19-0.96; P = 0.040). In all, 15 of the 37 patients with a sONB and four of the 39 patients with a rONB needed CIC. The cumulative risk of requiring CIC was significantly lower in the rONB group (10.3%) vs the sONB group (40.5%) (HR 0.22, 95% CI 0.07-0.67; P = 0.008) at 24 months. Multivariable Cox regression analysis also showed that the rONB type was an independently protective factor for sPVR and CIC. The rates of early (0-90 days) and late complication (>90 days) were 54.1% and 13.5% in the sONB group, and 64.1% and 10.3% in the rONB group, respectively. There were no significant differences in complications, urodynamic profile or ONB continence. A major limitation is the small sample size at a single centre.

CONCLUSION

Posterior support with round ligament for an ONB significantly improved the emptying of the ONB and resulted in a reduced need for CIC. The surgical modification is a feasible and safe technique without additional complication-related surgeries.

Modified wallace anastomotic technique reduces ureteroenteric stricture rates after ileal conduit urinary diversion

PURPOSE

To compare perioperative outcomes, complications and anastomotic stricture rate in a contemporary series of patients who underwent open radical cystectomy (RC) with modified Wallace anastomotic technique versus traditional ileal conduit.

MATERIALS AND METHODS

Study enrolled 180 patients, of whom 140 were randomized and underwent RC; seventy were randomized to group I and the seventy to the group II. For the primary objective, we hypothesized that the rate of ureteroenteric strictures would be at least 20 % lower in the second group. Secondary end points included rate of anastomotic leak, surgical time, deterioration of the upper tract, intraoperative blood loss and patient-reported quality of life (HRQOL). The modified Wallace 1 technique involved eversion of the ureteral plate and bowel mucosa edges, which were anastomosed together in running fashion, while the outher anastomotic wall was augmented with sero-serosal interrupted sutures.

RESULTS

The mean (SD) follow-up time was 26.1 (5.7) months in group I and 25.2 (4.8) months in group II, during which, anastomotic stricture was observed in 8 patients (12%) from the first and 2 patients (3%) from the second group (p < 0.05). The anastomotic leakage rate was significantly higher in first group (17% vs. 8.5%, p < 0.05), while patient-reported HRQOL outcomes were similar between groups after the 12 month follow-up period.

CONCLUSIONS

By using a modified Wallace technique, we were able to significantly lower anastomotic stricture and anastomotic leakage rates, which are major issues in minimizing both short- and long-term postoperative complications.

The short-term effects of tolterodine on nocturnal incontinence after ileal orthotopic neobladder: a randomised crossover placebo-controlled study

OBJECTIVES

To assess the effect of tolterodine in the treatment of nocturnal urinary incontinence (NUI) after ileal orthotopic neobladder (ONB).

PATIENTS AND METHODS

This is a prospective randomised placebo-controlled crossover study (clinicaltrials.gov: NCT02877901). Patients with NUI after ONB were randomly allocated into two equal groups. Group T received 4 mg extended-release tolterodine at bed-time and Group P received placebo for 4 weeks followed by 2 weeks of washout, then crossed over to the alternate therapy for 4 weeks. Patients were assessed by the number of pads used per night (PPN) and with the Arabic version of the International Consultation on Incontinence Modular Questionnaire-Short Form (ICIQ-SF) at both phases of the study. The outcomes were the rate of NUI improvement and medication adverse events.

RESULTS

Out of 172 patients, 150 and 122 patients were evaluated at both phases of the study. The mean ICIQ-SF scores and PPN were significantly decreased in Group T compared to Group P in both study phases (P < 0.001). In Group T, 15 (10%) and 11 (9%) patients became dry after the first allocation and crossover, respectively. In Group T, 60 (77.9%) patients reported improvement vs four (5.5%) in Group P (P < 0.001) after the first allocation. Similarly, 46 (73%) and seven (11.9%) patients showed improvement in groups T and P after the crossover, respectively (P < 0.001). Dry mouth occurred in 31 (20.8%) patients.

CONCLUSIONS

Tolterodine seems to be a good choice for treatment of NUI after radical cystectomy and ONB. However, further studies are needed to delineate the long-term effects and the associated urodynamic characteristics.

Robot-assisted radical cystectomy with totally intracorporeal urinary diversion: surgical and early functional outcomes through the learning curve in a single high-volume center

The aim of the study is to report surgical and early functional outcomes of first 100 patients undergoing robot-assisted radical cystectomy (RARC) with totally intracorporeal urinary diversion (ICUD) in a single center. The main surgeon (A.P.) attended a modular training program at a referring center mentored by a worldwide-recognized robotic surgeon (P.W.). The program consisted of: (a) 10 h of theoretical lessons; (b) video session (c) step-by-step in vivo modular training. Each procedure was performed as taught, without any technique variation. Demographics, intra-operative data and post-operative complications, along with early functional outcomes, were recorded for each patient. We retrospectively evaluated the first consecutive 100 patients submitted to RARC with totally ICUD from July 2015 to December 2018. Median age at surgery was 69 years (IQR 60-74). 52 (52%), 32 (32%), and 17 (17%) patients received orthotopic neobladder, ileal conduit and uretero-cutaneostomy, respectively. Median operative time was 410 min. A median number of lymph nodes retrieved were 27 and median estimated blood loss was 240 mL with median hospitalization time of 7 days. All procedures were completed successfully without open conversion. A statistically significant improvement was found in the late (30-90 post-operative days) post-operative complications (p = 0.02) and operative time for urinary derivation. At multivariate logistic regression model ASA score ≥ 3 (OR = 4.2, p = 0.002) and number of lymph nodes retrieved (OR = 1.16, p = 0.02) were found to be predictors of 90-day complications. An adequate modular training is paramount to obtain successful results and reduce the learning curve of RARC, as demonstrated by our experience.

Dual Prosthetic Implantation After Radical Cystoprostatectomy and Neobladder: Outcomes of the Inflatable Penile Prosthesis and Artificial Urinary Sphincter in Bladder Cancer Survivors

OBJECTIVES

To determine the impact of radical cystectomy and orthotopic neobladder (NB) diversion on device-related outcomes in patients who undergo subsequent placement of both, an artificial urinary sphincter (AUS) and 3-piece inflatable penile prosthesis.

MATERIALS AND METHODS

Using an institutional prosthetic database, we identified 39 patients who underwent radical cystectomy and NB and subsequent implantation of both prosthetic devices from 2003 to 2017. Patient demographics, perioperative data, and postoperative outcomes including prosthetic infection, mechanical failure, revision surgery, and functional outcomes were examined and compared to an appropriate matched group of patients (n = 48, non-neobladder group).

RESULTS

No intraoperative complications were observed. After median follow-up of 94 months (12-177 months), 1 patient developed an infection of their penile prosthesis and 4 patients developed an erosion of their AUS. In each case, the infection did not involve the other device. Two patients required revision surgery of their penile prosthesis due to mechanical failure (reservoir leak, n = 1; cylinder aneurysm, n = 1). Twenty-one patients underwent elective revision surgery to improve continence (cuff downsizing, n = 18; pressure-regulating balloon exchange, n = 3). There were 6 cases of AUS mechanical failure. No reservoir-related complications such as herniation or erosion were observed. Compared to the control group of non-neobladder patients, there were no significant differences in prosthetic infection, mechanical failure, and revision surgery.

CONCLUSION

The AUS and 3-piece inflatable penile prosthesis can coexist safely in patients with NB without an increased risk of device-related complications.

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.

Functional Assessment of the Hautmann Ileal Neobladder with Chimney Modification Using Uroflowmetry and a Questionnaire

Urinary diversion reconstruction is essential after radical cystectomy and neobladder reconstruction is accepted as a fine option. This study included 51 patients, who underwent radical cystectomy with orthotopic neobladder reconstruction by a Hautmann ileal neobladder with chimney modification from 2006 to 2014. Functional outcomes were evaluated using a questionnaire and uroflowmetry. Perioperative complications were analyzed retrospectively. The mean follow-up period was 36.1 months. Eighty-six percent of patients voided without clean intermittent catheterization (CIC) assistance. CIC was used 1-2x per day or every time they voided in 8% and 6% of patients, respectively, and 71% of patients were continent. The percentages of patients who used 1, 2, 3-4, and ≥5 pads per day were 15%, 6%, 2%, and 6%, respectively. Daytime and nighttime continence were achieved in 86% and 69% of patients, respectively. Daily mucus leakage was reported in 69% of patients. The mean maximum neobladder capacity, voided volume, postvoid residual volume, and maximum flow rate were 413.2 mL, 370.6 mL, 43.7 mL, and 20.8 mL/s, respectively. Eighteen early and 5 late complications developed in 13 and 5 patients, respectively. Reoperations were needed in 7 patients. The Hautmann ileal neobladder with chimney modification provided satisfactory results regarding functional outcomes.

Oncological and functional outcomes of postoperative total parenteral nutrition after radical cystectomy in bladder cancer patients: A single-center randomized trial

OBJECTIVES

To prospectively evaluate the long-term oncological and functional outcomes of postoperative total parenteral nutrition after radical cystectomy.

METHODS

A total of 157 consecutive patients (≤cT3, cN0, cM0) who underwent extended pelvic lymph node dissection, radical cystectomy and ileal urinary diversion from September 2008 to March 2011 at a single center were randomized to receive either postoperative total parenteral nutrition (group A; n = 74) or oral nutrition alone (group B; n = 83). All but two patients in group B (who were thus excluded from further analysis) had regular postoperative follow up at the Department of Urology, University of Bern, Switzerland. Computed tomography and bone scan were carried out to assess local recurrences and distal metastases. We used validated questionnaires to evaluate bowel function, sexual function and quality of life, and an institutional questionnaire to evaluate neobladder function.

RESULTS

The median follow up was 50 months (IQR 21-62). The rate of local recurrences (4/74 [5.4%] in group A; 4/81 [4.9%] in group B; P = 0.9) and the rate of distant metastases (23/74 [31%] in group A; 23/81 [28%] in group B; P = 0.72) did not differ between the two groups. There was no difference in cancer-specific (P = 0.86) and overall survival (P = 0.85). Group B patients had significantly better bowel function at 3 months (P = 0.03) and 12 months (P = 0.01). There was no difference in terms of quality of life, and sexual and neobladder function.

CONCLUSIONS

The administration of total parenteral nutrition after radical cystectomy does not impair long-term oncological outcomes. It does, however, negatively influence long-term bowel function.

[The W-shaped ileal neobladder: Long term functional outcomes and health-related quality of life]

PURPOSE

To evaluate functional outcomes and patients' health-related quality of life over ten years after a W-shaped ileal neobladder urinary diversion.

PATIENTS AND METHODS

From 1994 to 2004, 87 patients with bladder cancer underwent a cystoprostatectomy with a W-shaped ileal neobladder. Among them, 31 patients (35.6%) were evaluated. The average follow-up was 158months, average age was 72years. We assessed functional outcomes (use of protections, USP score, uroflowmetry, postvoid residual volume), overall health-related quality of life (SF-36 score), and specific urinary-related quality of life (Ditrovie scale).

RESULTS

Daytime continence was satisfactory in 29 patients (96.8%). Night-time continence was satisfactory in 27 patients (87.1%). Mean daytime continence, hyperactivity and dysuria scores of the USP were respectively 1.5/9, 3.2/21 and 2/9. Mean value of the maximum flow rate was 18mL/s for an average voiding volume of 324mL and an average postvoid residual volume of 70mL. The 8 dimensions of the SF-36 were all comparable with the French population's values. According to the Ditrovie scale whose average value was 1.83, the health-related quality of life was unchanged or little changed by urinary disorders in 28 patients (90.3%).

CONCLUSIONS

Our results suggest that voiding status and health-related quality of life remain satisfactory over ten years after an orthotopic ileal neobladder derivation.

Patients with an Orthotopic Low Pressure Bladder Substitute Enjoy Long-Term Good Function

PURPOSE

Orthotopic bladder substitution has been performed on a regular basis for more than 30 years and yet data on long-term functional outcomes are still lacking.

MATERIALS AND METHODS

We evaluated 181 men and 19 women who underwent radical cystectomy and urinary diversion with ileal orthotopic bladder substitution from 1985 to 2004 and who had 10 years or more of followup.

RESULTS

Median age at radical cystectomy was 63 years (IQR 57-69). Median followup was 167 months (IQR 137-206). Daytime and nighttime continence rates peaked 24 months postoperatively and decreased slightly thereafter during almost 2 decades. At 10, 15 and 20 years daytime continence rates were 92%, 90% and 79%, and nighttime continence rates were 70%, 65% and 55%, respectively. During the day and at night fewer than 3% and 10% of patients, respectively, had urine loss 100 ml or greater at any time 10 years or longer after surgery. At 10 and 20 years 11 of 200 patients (6%) and 1 of 29 (3%), respectively, had to perform clean intermittent self-catheterization. After an initial postoperative decrease in the estimated glomerular filtration rate the subsequent decrease was less than 1 ml/minute/1.73 m(2) per year. A total of 81 complications were observed in 42 of the 200 patients (21%) 10 years or longer after radical cystectomy with pyelonephritis as the most frequent cause.

CONCLUSIONS

Patients who survive up to 20 years after radical cystectomy and diversion with an ileal orthotopic bladder substitution may enjoy satisfactory urinary continence and retain the ability to void spontaneously while experiencing no more than a physiological decrease in renal function.

Long-term Functional, Urodynamic, and Metabolic Outcome of a Modified Orthotopic Neobladder Created With a Short Ileal Segment: Our 5-year Experience

OBJECTIVE

To assess the long-term functional, urodynamic, and metabolic outcomes of our modified neobladder.

MATERIALS AND METHODS

In this prospective study from January 2010 to October 2014, 42 consecutive male patients with bladder tumor underwent radical cystectomy and orthotopic urinary diversion with modified ileal neobladder using 25 cm ileal segment. During follow-up, functional outcome, urodynamic studies, metabolic parameters, and renal parameters were assessed at regular intervals. Complications were graded as early (<3 months) or late (>3 months).

RESULTS

There were no perioperative deaths. At a mean follow-up of 27.2 months, good or satisfactory daytime and nighttime continence were achieved in 100% and 93.8% of patients, respectively. Mean maximal bladder capacity was 588 mL at 3 years. Mean resting pressure and voiding pressures were 20.1 cm H2O and 34.6 cm H2O at 3 years, respectively. Good bladder compliance was achieved in all patients by 1 year. Mean maximum urine flow rate (Qmax) was 18.5 mL at 3 years. Postvoid residual volume was insignificant in all the patients and none of the patients were on clean intermittent self-catheterization. None of the patients developed severe metabolic acidosis. Vitamin B12 levels were within normal range in all patients. Early complications were seen in 12 patients (28.6%), whereas late complications were observed in 5 patients (12%).

CONCLUSION

Our results demonstrate that our modified technique of using a short ileal segment to create a near-spherical, compliant, low-pressure reservoir provides an acceptable, safe, and functional alternative to the standard Hautmann neobladder.

Intravesical OnabotulinumtoxinA Injection for Overactive Orthotopic Ileal Neobladder: Feasibility and Efficacy

The efficacy of intravesical onabotulinumtoxinA (BTXA) in the treatment of overactive bladder (OAB) has been well documented. The use of BTXA injection in orthotopic neobladders is yet to be studied. We present 4 cases of patients injected with intravesical BTXA for overactive orthotopic ileal neobladder. We recorded patient demographics, presenting and follow-up symptoms, urodynamic profiles, and Patient Global Impression of Improvement (PGI-I) scores. The 4 patients reported varying degrees of subjective improvements in the symptoms, including urgency, urge incontinence, and pad usage. Mean follow-up duration was 8.3 months (range, 5-14 months). Average PGI-I score was 3 ("a little better") (range, 2-4). To our knowledge, the current study is the first case series examining BTXA injection for orthotopic neobladder overactivity. BTXA injection yielded varying degrees of objective and subjective improvements, without significant complications. Intravesical BTXA injection is feasible and may be considered as a potential treatment alternative for OAB in orthotopic neobladders, although further study is warranted.

Ves.Pa.-Designing a Novel Robotic Intracorporeal Orthotopic Ileal Neobladder

OBJECTIVE

To present a detailed description of the "Ves.Pa." procedure to create a novel robotic intracorporeal ileal orthotopic neobladder, together with technical tips for the creation of a time-efficient robotic intracorporeal neobladder.

MATERIALS AND METHODS

We evaluated the presumed volume of the final Ves.Pa. in silico, exploring ex vivo the anatomical and technical feasibility of reconfiguring the bowel. During tests performed in a robotic pelvic model, procedures were recorded to identify possible improvements in operating times.

RESULTS

After initial evaluation of the anatomical feasibility of the technique, its practicability was confirmed during ex vivo tests. It is also possible to create two different versions of the pouch, in cases of short right or short left ureter ("Ves.Pa. Reverse"). Tests on our robotic pelvic model confirmed the feasibility of the technique, and some details to improve its time efficiency were identified, for example, further simplification of the suturing of the neobladder.

CONCLUSION

Despite the increasing use of robotic radical cystectomy, most urological departments do not perform "ideal" intracorporeal urinary diversion due to perceived technical difficulties in reconfiguring the ileum and operating times in comparison with open surgery. An idea for a novel intracorporeal robotic orthotopic neobladder (with many characteristics for creating a feasible test pouch) has been designed. Clinical studies are needed to confirm these findings.

There is a place for radical cystectomy and urinary diversion, including orthotopic bladder substitution, in patients aged 75 and older: Results of a retrospective observational analysis from a high-volume center

INTRODUCTION

The incidence of cancer increases with age and owing to the changing demographics we are increasingly confronted with treating bladder cancer in old patients. We report our results in patients>75 years of age who underwent open radical cystectomy (RC) and urinary diversion.

MATERIAL AND METHODS

From January 2000 to March 2013, a consecutive series of 224 old patients with complete follow-up who underwent RC and urinary diversion (ileal orthotopic bladder substitute [OBS], ileal conduit [IC], and ureterocutaneostomy [UCST]) were included in this retrospective single-center study. End points were the 90-day complication rates (Clavien-Dindo classification), 90-day mortality rates, overall and cancer-specific survival rates, and continence rates (OBS).

RESULTS

Median age was 79.2 years (range: 75.1-91.6); 35 of the 224 patients (17%) received an OBS, 178 of the 224 patients (78%) an IC, and 11 of the 224 patients (5%) an UCST. The 90-day complication rate was 54.3% in the OBS (major: Clavien grade 3-5: 22.9%, minor: Clavien Grade 1-2: 31.4%), 56.7% in the IC (major: 27%, minor: 29.8%), and 63.6% in the UCST group (major: 36.4%, minor: 27.3%); P = 0.001. The 90-day mortality was 0% in the OBS group, 13% in the IC group, and 10% in the UCST group (P = 0.077). The Glasgow prognostic score was an independent predictor of all survival parameters assessed, including 90-day mortality. Median follow-up was 22 months. Overall and cancer-specific survivals were 90 and 98, 47 and 91, and 11 and 12 months for OBS, IC, and UCST, respectively. In OBS patients, daytime continence was considered as dry in 66% and humid in 20% of patients. Nighttime continence was dry in 46% and humid 26% of patients.

CONCLUSION

With careful patient selection, oncological and functional outcome after RC can be good in old patients. Old age as the sole criterion should not preclude the indication for RC or the option of OBS. In old patients undergoing OBS, satisfactory continence results can be achieved.

Robotic Intracorporeal Orthotopic Neobladder: Urodynamic Outcomes, Urinary Function, and Health-related Quality of Life

BACKGROUND

Intracorporeal orthotopic neobladder (iONB) creation following robotic radical cystectomy is an emerging procedure and robust functional data are required.

OBJECTIVE

To evaluate urodynamic features of iONB and bladder cancer-specific and general health-related quality-of-life (HRQOL) outcomes.

DESIGN, SETTING, AND PARTICIPANTS

We retrospectively assessed 28 men who underwent iONB creation (January 2012 to October 2013) and compared results to a previously characterized cohort of 79 of open ONB procedures.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

iONB pressure-volume properties were characterized using multichannel urodynamics (UDS). The Bladder Cancer Index (BCI) questionnaire, modified with mucus- and pad-related questions, and the Short Form Health Survey (SF-36) were used to evaluate urinary function and HRQOL. ONB cohorts were compared for functional outcomes and BCI score. Multivariable linear regression was used to assess predictors of BCI score.

RESULTS AND LIMITATIONS

The median follow-up was 9.4 mo for the iONB and 62.1 mo for the open ONB group (p<0.0001); ≥2-yr follow-up had been completed for one (4%) patient in the iONB group compared to 75 (95%) patients in the open ONB group (p<0.0001). In UDS tests, the iONB group had minimal postvoid residual volume, normal compliance, and a mean capacity of 514 cm(3) (range 339-1001). BCI mean scores for urinary function (p=0.58) and urinary bother (p=0.31) were comparable between the groups. The surgical approach was not associated with the BCI score on multivariable analysis. Rates of 24-h pad use were comparable between iONB and open ONB groups (pad-free 17% vs. 19%; ≤2 pads 84% vs. 79%), as reflected by total pad usage (p=0.1); pad size and daytime wetness were worse in the iONB group. The clean intermittent catheterization rate was 10.7% in the iONB and 6.3% in the open ONB group. Limitations include the retrospective comparison, small number of patients and short follow-up for the iONB group.

CONCLUSIONS

iONB had adequate UDS characteristics and comparable bladder cancer-specific HRQOL scores to open ONB. However, pad size and daytime wetness were worse for iONB, albeit over significantly shorter follow-up.

PATIENT SUMMARY

We demonstrate that the volumetric and pressure characteristics are acceptable for a neobladder created using an entirely robot-assisted laparoscopic technique after bladder removal for cancer. Urinary function and quality-of-life outcomes related to the robotic technique were compared to those for neobladders created via an open surgical technique. We found that urinary function and bother indices were comparable; however, the robotic group required larger incontinence pads that were wetter during the daytime. This may be explained by the significantly shorter duration of recovery after surgery in the robotic group.

[Treatment of invasive bladder cancer: robot-assisted radical cystectomy and intracorporeal urinary diversion]

PURPOSE

Robot-assisted radical cystectomy (RARC) and intracorporeal urinary diversion are only performed in a few centers of excellence worldwide. Functional and oncologic outcomes are comparable. We report on our experience with RARC and intracorporeal diversion.

PATIENTS AND METHODS

We retrospectively identified 86 RARCs in 72 men and 14 women (mean age 69.7 years). All patients underwent robot-assisted radical cystectomy and pelvic lymphadenectomy followed by intracorporeal urinary diversion using ileal conduit or neobladder. Of the 86 patients, 24 patients (28%) underwent intracorporeal ileal conduit and 62 patients (72%) underwent intracorporeal neobladder formation. A Studer pouch was created in all who underwent intracorporeal neobladder diversion. Cancer specific survival (CSS) and overall survival (OS) are reported.

RESULTS

The mean operative time was 418.9 min (range 205-690 min) and blood loss was 380 ml (range 100-1000 ml). The mean hospital stay was 17.5 days (range 5-62 days). All the surgeries were completed with no open conversions. Minor complications (grade I and II) were reported in 23 patients, while major complications (grade III and above) were reported in 21 patients. The mean nodal yield was 20.3 (range 0-46). Positive margins were found in in 8%. The average follow-up was 31.5 months (range 3-52 months). Continence could be achieved in 88% of patients who received an intracorporeal neobladder. The cancer-specific survival (CSS) and overall survival (OS) were 80% and 70%, respectively.

CONCLUSION

RARC with intracorporeal diversion seems to be safe and reproducible in tertiary centers with robotic expertise. Operative times are acceptable and complications as well as functional and oncologic outcomes are comparable. Further standardization of RARC with intracorporeal diversion may lead to a wider adoption of the approach.

Clinical evaluation of patients treated with a detubularised isolated ureterosigmoidostomy diversion after radical cystectomy

OBJECTIVES

To assess the emptying pattern and patient satisfaction after constructing a detubularised isolated ureterosigmoidostomy (DIUS) following a cystectomy, introduced to overcome the poor outcome of conventional ureterosigmoidostomy, to improve the emptying pattern and accordingly patients' quality of life.

PATIENTS AND METHODS

The study included 122 patients who were treated with a DIUS diversion after cystectomy. The minimum follow-up of the patients was 6 months. The frequency of emptying and continence during the day and night were recorded. The ability of the patients to discriminate between urine and stool was assessed. The patients' overall satisfaction with the outcome was categorised as fully satisfied, moderately satisfied or not satisfied.

RESULTS

In all, 95 patients were available for this evaluation; all patients were completely continent during the day and night. The mean emptying frequency was 3.9 during the day and 1.7 during the night. All patients were able to feel the desire to empty and the mean holding time was 35 min. Fifty-two patients (55%) could pass solid stools once per day, with minimal urine at the end of voiding, and the remaining evacuations were of clear urine only. Thirty-two patients (34%) were able to differentiate between urine and stool sensation before emptying. For satisfaction, 82 patients reported full satisfaction, 13 were moderately satisfied, and none regretted the diversion.

CONCLUSIONS

The DIUS diversion provides continence during the day and night, with a satisfactory emptying habit. Patients with a DIUS diversion can tolerate a full pouch comfortably, with no leakage, and they can discriminate between urine and stool evacuations.

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.

Prostate-sparing cystectomy: has Pandora’s box been opened?

En bloc removal of the prostate has traditionally been an integral component of radical cystectomy for men with bladder cancer owing to a high incidence of occult prostatic malignancy. However, the risk of functional morbidity following this procedure is considerable and can delay patient acceptance of cystectomy, which can adversely affect the long-term prognosis. Recently, some investigators have advocated prostate-sparing cystectomy (PSCx) to improve postoperative continence and potency rates, and this may also improve timely patient acceptance of cystectomy. Several of these PSCx series describe excellent functional results postoperatively and PSCx may also facilitate a laparoscopic approach, offering further dividends. However, valid concerns regarding the oncologic efficacy of this procedure still predominate and protocols for patient selection, technique and postoperative surveillance are not well defined. The concept of PSCx is arguably one of the most controversial topics in the field of bladder cancer today.

Orthotopic neobladder perforation: an unusual presentation of small bowel obstruction

Orthotopic bladder reconstruction is becoming increasingly popular in patients who have undergone radical cystectomy. One of the rare complications is spontaneous rupture, which presents with various symptoms, but in particular, abdominal pain. We report a case of orthotopic bladder perforation in a patient who presented with the symptoms and signs of small bowel obstruction.

Radical cystectomy with W-shaped orthotopic ileal neobladder constructed with non-absorbable titanium staples-long term follow-up

PURPOSES

We retrospectively assessed our experience with the W-shaped orthotopic ileal pouch, which was constructed with non-absorbable titanium staples. For these purpose, we discuss the results of bladder capacity, urinary continence and early and long-term postoperative complications.

MATERIALS AND METHODS

We included in the study 17 patients who underwent radical cystoprostatectomy followed by construction of an orthotopic W-shaped ileal pouch between October 2000 and November 2009. A 65-70 cm segment of ileum was isolated and prearranged into a W-configuration, leaving two 10 cm intact segments on both sides of the ileal fragment. In our technique we entirely anatomized all adjacent limbs in order to create a sphere-shaped pouch. The ureters were directly anastomized to both intact segments of the ileal division. All our patients underwent pouchscopy 6 months after operation and annually.

RESULTS

Mean operative time for neobladder reconstruction and ureteral anastomoses was 87 ± 7.67 minutes. In one patient a leak from the ileo-ileal anastomosis was confirmed on the 3rd day after operation. In 2 cases unilateral stricture of the ureteral-neobladder anastomosis was documented. Staple lines were mostly covered with ileal mucosa after 6 months. The mean functional bladder capacity was 340 ± 27.6 mL and 375 ± 43.4 mL at 6 and 12 months, respectively. First-year daytime and nighttime continence was good and acceptable in 90% and 78% of patients, while it increased to 95% during the 2nd year.

CONCLUSIONS

The long term follow-up shows that non-absorbable titanium staples can be safely used for creation of an orthotopic ileal neobladder. However, these data should be further validated in a larger series of patients.

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.

[Cystectomy in the elderly patient]

Bladder cancer is a carcinoma of the elderly population. The highest incidence of bladder cancer is between the ages of 70 and 80 years old. Radical cystectomy remains the gold standard for muscle invasive bladder cancer treatment. In this article different aspects of radical cystectomy in elderly patients are reviewed. The Pubmed-MEDLINE database was searched using the following keywords: radical, cystectomy, elderly and age.

Neobladder long term follow-up

One of the commonest forms of orthotopic bladder substitution for bladder cancer survivors, used in our institute, is the use of ileocecal segment. Sometimes, the need for Indiana pouch heterotropic continent diversion arises.

AIM

To compare the long-term effect of orthotopic ileocecal bladder and heterotropic Indiana pouch following radical cystectomy in bladder cancer patients.

PATIENTS AND METHODS

Between January 2008 and December 2011, 91 patients underwent radical cystectomy/anterior pelvic exentration and orthotopic ileocecal bladder reconstruction (61 patients) and Indiana pouch (30 patients), when orthotopic diversion could not be technically or oncologically feasible.

RESULTS

Convalescence was uneventful in most patients. All minor and major urinary leakage cases, in both diversions groups, where successfully conservatively treated. Only one patient in the ileocecal group with major urinary leak required re-exploration with successful revision of uretro-colonic anastomosis. Only one patient in the Indiana pouch group had accidentally discovered sub-centimetric stone, which was simply expelled. The overall survival proportion of ileocecal group was 100% compared to 80% in the Indiana pouch group (p<0.001). The disease free survival proportion of ileocecal group was 90.8% compared to 80% in the Indiana pouch group (p=0.076). Effective comparative daytime and nighttime urinary continence as well as renal function deterioration were not statistically significant between both reconstruction types.

CONCLUSION

Both ileocecal bladder and Indiana pouch are safe procedures in regard to long-term effects over kidney function following radical cystectomy.

[Radical cystectomy and ileal neobladder reconstruction in elderly female patients over 70 years old: morbidity, functional and oncological long-term results]

BACKGROUND

As life expectancy is increasing the incidence and therefore the number of elderly female patients with bladder cancer is also increasing. The aim of this study was to assess long-term clinical, functional and oncological outcome in elderly women (≥70 years) who were treated by radical cystectomy and ileal neobladder reconstruction for invasive bladder cancer.

MATERIAL AND METHODS

A total of 121 women with clinically organ-confined invasive urothelial carcinoma underwent radical cystecomy with an orthotopic ileal neobladder in Ulm between 1995 and 2010. The clinical course, functional, pathological, and oncological outcome of these women were analyzed retrospectively and compared between patients ≥70 (n=24) and <70 years of age (n=97). All complications which occurred during the first 90 days after surgery were analyzed in detail, defined and classified according to the modified Clavien system.

RESULTS

The overall 90 day complication rates were 66.7 % and 62.5 % for patients ≥70 and <70 years, respectively. Of these 54.2% and 44.8% were minor complications and 12.5 % and 17.7 % were major complications, respectively. Infections were the most frequent cause of complications with 36.7 %. Univariate analyses revealed that neither age nor comorbidity (ASA score) were significant predictors of perioperative complications. The daytime continence rates were comparable in both age groups (71% versus 82%, p=0.64); however, younger patients showed significantly higher night time urinary continence rates (43% versus 89%, p=0.013). Neither univariable nor multivariable analyses indicated that age ≥70 years had a significant impact on tumor-specific survival.

CONCLUSIONS

Chronological age per se does not seem to be a contraindication for the creation of an orthotopic ileal neobladder; however, the risk of postoperative incontinence seems to increase with age.

Robotic intracorporeal orthotopic ileal neobladder: replicating open surgical principles

BACKGROUND

Robotic radical cystectomy (RC) for cancer is beginning to gain wider acceptance. Yet, the concomitant urinary diversion is typically performed extracorporeally at most centers, primarily because intracorporeal diversion is perceived as technically complex and arduous. Previous reports on robotic, intracorporeal, orthotopic neobladder may not have fully replicated established open principles of reservoir configuration, leading to concerns about long-term functional outcomes.

OBJECTIVE

To illustrate step-by-step our technique for robotic, intracorporeal, orthotopic, ileal neobladder, urinary diversion with strict adherence to open surgical tenets.

DESIGN, SETTING, AND PARTICIPANTS

From July 2010 to May 2012, 24 patients underwent robotic intracorporeal neobladder at a single tertiary cancer center. This report presents data on patients with a minimum of 3-mo follow-up (n=8).

SURGICAL PROCEDURE

We performed robotic RC, extended lymphadenectomy to the inferior mesenteric artery, and complete intracorporeal diversion. Our surgical technique is demonstrated in the accompanying video.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Baseline demographics, pathology data, 90-d complications, and functional outcomes were assessed and compared with patients undergoing intracorporeal ileal conduit diversion (n=7).

RESULTS AND LIMITATIONS

Robotic intracorporeal urinary diversion was successfully performed in 15 patients (neobladder: 8 patients, ileal conduit: 7 patients) with a minimum 90-d follow-up. Median age and body mass index were 68 yr and 27 kg/m2, respectively. In the neobladder cohort, median estimated blood loss was 225 ml (range: 100-700 ml), median time to regular diet was 5 d (range: 4-10 d), median hospital stay was 8 d (range: 5-27 d), and 30- and 90-d complications were Clavien grade 1-2 (n=5 and 0), Clavien grade 3-5 (n=2 and 1), respectively. This study is limited by small sample size and short follow-up period.

CONCLUSIONS

An intracorporeal technique of robot-assisted orthotopic neobladder and ileal conduit is presented, wherein established open principles are diligently preserved. This step-wise approach is demonstrated to help shorten the learning curve of other surgeons contemplating robotic intracorporeal urinary diversion.

Radical cystectomy and orthotopic bladder substitution using ileum

Over the past decade, continent urinary diversion, especially orthotopic bladder substitutions, has become increasingly popular following radical cystectomy for bladder cancer. The ultimate goal of orthotopic bladder substitution is to offer patients the best quality of life, similar to that of patients with native bladders. To achieve that purpose, surgeons should be familiar with the characteristics of good candidates for neobladders, the possible intraoperative and postoperative problems related to the surgery, and the solutions to these problems. Postoperative surveillance and instructions given to the patients also contribute to successful, functional results. Here, we reviewed the indications, pitfalls, and solutions for orthotopic bladder substitutions and the patients' quality of life after surgery. When performed properly, orthotopic continent diversion offers good quality of life with few long-term complications. Therefore, we believe it is the best option for the majority of patients requiring cystectomy.

The effect of age on bladder cancer incidence, prognosis and therapy

Age is now widely accepted as the single greatest risk factor for developing urothelial carcinoma of the bladder (UCB). The aim of this article is to assess the incidence, prognosis and therapy of UCB in the elderly. Using MEDLINE, we performed a search of the literature between January 1966 and July 2009. The link between aging and cancer is more complex than the simple passage of time; certain genes may be activated while others may be suppressed with advancing age. Treatments for nonmuscle-invasive UCB are generally well-tolerated by the elderly. However, several studies have demonstrated a lower response rate to intravesical immunotherapy in the elderly. While elderly patients have a higher rate of perioperative complication and mortality after radical cystectomy, the difference is too small and insufficient to avoid radical cystectomy in these patients. Similarly, in certain selected cases, centers of excellence report similar complication rates in elderly patients, regardless of the type of urinary diversion. The optimal application of perioperative chemotherapy is dependent on the degree of compromise of the organ systems through comorbid conditions and physiologic deterioration. Restrictive case selection and proactive postoperative rehabilitation are important for elderly patients to obtain good results. Age alone does not preclude optimal treatment for patients with aggressive UCB. Radical surgery, urinary diversion and systemic chemotherapy are feasible, safe and efficacious in the treatment of adequately selected elderly UCB patients. It is imperative that healthcare practitioners and researchers from disparate disciplines collectively focus their efforts to appropriately meet the multifaceted medical and psychosocial needs of the elderly.
