Urodynamic Parameters and Continence Outcomes in Asymptomatic Patients with Ileal Orthotopic Neobladder: A Systematic Review and Metanalysis. Cancers (Basel) 2024; 16:1253. [PMID: 38610933 PMCID: PMC11010941 DOI: 10.3390/cancers16071253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 03/19/2024] [Accepted: 03/19/2024] [Indexed: 04/14/2024] Open
Abstract
INTRODUCTION The orthotopic neobladder is the type of urinary diversion (UD) that most closely resembles the original bladder. However, in the literature the urodynamic aspects are scarcely analysed. OBJECTIVE To provide the first systematic review (SR) on the urodynamic (UDS) outcomes of the ileal orthotopic neobladders (ONB). Continence outcomes are also presented. METHODS A PubMed, Embase and Cochrane CENTRAL search for peer-reviewed studies on ONB published between January 2001-December 2022 was performed according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. RESULTS AND CONCLUSION Fifty-nine manuscripts were eligible for inclusion in this SR. A great heterogeneity of data was encountered. Concerning UDS parameters, the pooled mean was 406.2 mL (95% CI: 378.9-433.4 mL) for maximal (entero)cystometric capacity (MCC) and 21.4 cmH2O (95% CI: 17.5-25.4 cmH2O) for Pressure ONB at MCC. Postvoid-residual ranged between 4.9 and 101.6 mL. The 12-mo rates of day and night-time continence were 84.2% (95% CI: 78.7-89.1%) and 61.7% (95% CI: 51.9-71.1%), respectively.Despite data heterogeneity, the ileal ONB seems to guarantee UDS parameters that resemble those of the native bladder. Although acceptable rates of daytime continence are reported the issue of high rates of night-time incontinence remains unsolved. Adequately designed prospective trials adopting standardised postoperative care, terminology and methods of outcome evaluation as well as of conduction of the UDS in the setting of ONB are necessary to obtain homogeneous follow-up data and to establish UDS guidelines for this setting.

Abstract
BACKGROUND The incidence of common urinary system tumors has been rising rapidly in recent years, and most urinary system-derived tumors lack specific biomarkers. OBJECTIVES To explore the efficacy of surface-enhanced Raman spectroscopy (SERS) of blood plasma in screening three common urinary system tumors, including bladder cancer (BC), prostate cancer (PCa), and renal cell carcinoma (RCC). METHODS SERS plasma spectra from 125 plasma samples, including 25 PCa, 38 RCC, 24 BC patients, and 38 normal volunteers, were collected. All candidates had no other comorbidities. The Diagnosis was based on the combination of Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA), and the effectiveness of the diagnostic algorithms was verified using the Receiver Operating Characteristic Curve (ROC). RESULTS There are significant differences in SERS signals between PCa, BC, RCC, and normal plasma, especially at 639, 889, 1010, 1136, and 1205 cm-1. The PCA-LDA results show that high sensitivity (100 %), specificity (100 %), and accuracy (100 %) could be achieved for screening the PCa, RCC, BC group vs. the normal group, the PCa group vs. the BC and RCC group, respectively. The diagnostic sensitivity, specificity, and accuracy for the BC group vs. the RCC group are 79.2 %, 71.1 %, and 75.15 %, respectively. The integrated area under the ROC curve (AUC) is 1.0, 1.0, and 1.0 for the PCa, RCC, and BC group vs. the normal group, respectively. The AUC of the PCa group vs. the BC group and RCC group and the BC group vs. the RCC group are 1.0, 1.0, and 0.842, respectively. CONCLUSIONS Label-free plasma-SERS technology with PCA-LDA analysis could be a useful screening method for detecting urinary system tumors (PCa, RCC, and BC) in this exploratory study.

Impact of the Ileal Width on the Capacity of the Orthotopic Neobladder: The AADAPT Formula Tested on the Animal Model. EUR UROL SUPPL 2023; 58:55-63. [PMID: 38152481 PMCID: PMC10751539 DOI: 10.1016/j.euros.2023.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/17/2023] [Indexed: 12/29/2023] Open
Abstract
Background The capacity of a given shape of an orthotopic ileal neobladder (ONB) varies significantly, although the same length of preterminal ileum is utilised. Objective To investigate the variability of the human ileal width and to create a mathematical formula that calculates its impact on the neobladder capacity. Design setting and participants During 50 consecutive cases of robotic pelvic surgery, a segment of preterminal ileum was identified and the width was measured. A mathematical formula was created to calculate, for a given ileal length and width, the neobladder capacity and, for a given ileal width and neobladder capacity, the length of the (pre)terminal ileum to harvest. The accuracy of our model was tested on 28 pouches created by swine ileum. Outcome measurements and statistical analysis The interindividual variability of the ileal width and its impact on the ileal neobladder capacity was investigated. Results and limitations The mean hemicircumference of the human distal ileum is 2.43 ± 0.39 cm (range 2-3.5 cm). According to our geometric model and as confirmed in the swine model, an increase of 1 cm in ileal width increases the neobladder capacity by 85%. The Pearson correlation coefficient reported a strong positive relationship between the formula-calculated and effective volumes of the pouch (r = 0.97). Moreover, for the same target capacity, 1 cm of difference in the ileal width implies harvesting 20 cm less ileum. A lack of testing on humans and application only to spheroidal neobladders are the main limits. Conclusions The ileal width impacts the capacity of the ONB. For a given type of ONB, no standard length of ileum should be harvested; instead, the length should be tailored to the width of the ileum for a given patient. Clinical studies are required to confirm our model. Patient summary We demonstrated the variability of the ileal width among humans, and we provided a mathematical formula tested on swine that evaluates the impact of the ileal width on the capacity of the orthotopic ileal neobladder.

Abstract
BACKGROUND Laparoscopic radical cystectomy (LRC) with ileal orthotopic neobladder (IONB) reconstruction is one of the most promising methods for bladder cancer treatment; its advantages include a small incision size, less blood loss, improved perioperative outcome and tumor prognosis, and a positive self-image postoperatively. The short-term benefits of various IONB reconstruction procedures reported thus far include a simple process, short operative time, less intraoperative bleeding, few postoperative complications, and good postoperative neobladder function; in the long term, these benefits engender good quality of life of the patients. Here, we explored and summarized the more novel and available IONB reconstruction procedures to identify the safest, most efficient, and simplest IONB reconstruction techniques for patients with bladder cancer. SUMMARY LRC with IONB reconstruction is technically feasible; however, most of the relevant studies have been short, employing a small sample size and a retrospective design. However, long-term, large-scale, prospective studies identifying the most appropriate bowel segments for IONB reconstruction, comparing intracorporeal and extracorporeal IONB reconstruction, assessing currently available IONBs, and resolving relevant postoperative complications further, with a focus on patients with bladder cancer, are warranted. KEY MESSAGE Several procedures for LRC with IONB reconstruction have been reported thus far. However, there is no consensus regarding the IONB reconstruction procedures most beneficial to patients with bladder cancer. Our review may aid researchers in developing a simple, safe, and efficient LRC with IONB reconstruction procedure for patients with bladder cancer.

Abstract
BACKGROUND Robotic-assisted radical cystectomy (RARC) with neobladder reconstruction has gained popularity in recent years. METHODS We conducted a retrospective study of 17 consecutive patients who underwent RARC with totally intracorporeal J-pouch neobladder reconstruction without ureteral stent by a single experienced surgeon to evaluate perioperative, oncological and functional outcomes. RESULTS The median follow-up duration was 32.8 months (range: 17.4-59.0 months), and the 2-year disease-free survival rate was 88.2%. Five out of 12 patients were totally continent, and none required more than one pad per day. The overall complication rate was 41.2%, and hydronephrosis was the most common adverse event. The renal function remained stable, and no long-term renal function impairment was detected. CONCLUSION Our study suggests that RARC with totally intracorporeal J-pouch neobladder reconstruction without ureteral stent is a safe and feasible option for the treatment of muscle-invasive bladder cancer, with good oncological and functional outcomes.

Abstract
BACKGROUND To explore a method of constructing an orthotopic ileal neobladder (ONB) in the Y-pouch configuration. We describe the steps followed to create the Y-pouch ileal orthotopic neobladder (ONB) and compared the perioperative, functional, and urodynamics outcomes with the Studer neobladder technique. METHODS A retrospective cohort study of 90 bladder cancer patients, who received open radical cystectomy with the ONB performed at a hospital from June 2009 to May 2020. These patients were divided into two groups-the Y-pouch and the Studer neobladder groups. Perioperative, functional outcome, complication, renal function data outcomes, and pressure-volume study were used to evaluate the treatment outcomes after a radical cystectomy. RESULTS Ninety patients (54 Studer and 36 Y-pouch neobladder) were enrolled. The median patient age was 62.6 (± 11) years. The mean operative time for the Studer technique was 290 (242.5-350) min, and the Y-pouch technique was 300 (271.2-335) min) (p = 0.826). At 30 days postoperatively, the Clavien-Dindo classification of surgical complications revealed grade-2 urinary infections in two patients (5.6%) and six patients (11.1%) for the Y-pouch and Studer techniques, respectively. Intermediate complications (30-90 days) were reported in 4 (11.1%) and 18 patients (44.4%) in the Y-pouch and the Studer techniques, respectively (p = 0.062). In the urodynamics study (UDS), the Y-pouch group had a mean postvoid residual volume of 20 mL and Studer of 40 ml (p = 0.06). A mean capacity of 462 (380-600) mL compares to the Studer neobladder group with 495 (400-628) mL. The average mean compliance of the Studer group was 35.5 (28-52) ml/cm H2O and 33 (30-43) ml/cm H2O for Y pouch, and most patients had > 30 ml/cm H2O compliance (80/90 patients). CONCLUSIONS The Y-pouch neobladder technique in an RC with an orthotopic neobladder provides perioperative and functional outcomes compared to those of the Studer orthotopic neobladder resulting in similar intermediate-term. Therefore, the Y-pouch ileal neobladder is both feasible and safe to be used as a standard neobladder technique for urinary diversion in patients with bladder cancer undergoing radical cystectomy and needs confirmation with long-term results.

Abstract
Open radical cystectomy (ORC) is associated with high rates of perioperative morbidity and mortality, owing to its extensive surgical nature and the high frequency of multiple co-morbidities among patients. As an alternative, robot-assisted radical cystectomy (RARC) has been increasingly adopted worldwide, being a reliable treatment option that utilizes minimally invasive surgery. Seventeen years have passed since the advent of the RARC, and comprehensive long-term follow-up data are now becoming available. The present review focuses on the current knowledge of RARC in 2023, and analyzes various aspects, including oncological outcomes, peri/post-operative complications, post-operative quality of life (QoL) change, and cost-effectiveness. Oncologically, RARC showed comparable oncological outcomes to ORC. With regard to complications, RARC was associated with lower estimated blood loss, lower intraoperative transfusion rates, shorter length of stay, lower risk of Clavien-Dindo grade III-V complications, and lower 90-day rehospitalization rates than ORC. In particular, RARC with intracorporeal urinary diversion (ICUD) performed by high-volume centers significantly reduced the risk of post-operative major complications. In terms of post-operative QoL, RARC with extracorporeal urinary diversion (ECUD) showed comparable results to ORC, while RARC with ICUD was superior in some respects. As the RARC implementation rate increases and the learning curve is overcome, more prospective studies and randomized controlled trials with large-scale patients are expected to be conducted in the future. Accordingly, sub-group analysis in various groups such as ECUD, ICUD, continent and non-continent urinary diversion, etc. is considered to be possible.

Abstract
PURPOSE Few data exist regarding the functional outcomes of robot-assisted radical cystectomy (RARC) with intracorporeal orthotopic neobladder. The aim of this study was to evaluate the urodynamic and functional outcomes in patients undergoing RARC and totally intracorporeal orthotopic neobladder for bladder cancer. METHODS In this monocentric, observational study carried out between 2016 and 2020, consecutive patients undergoing RARC and intracorporeal orthotopic neobladder in the Department of Urology, Pitié-Salpêtrière Hospital, were included. Reconstruction was totally intracorporeal Y-shaped neobladder. Main outcomes were urodynamic findings 6 months post-surgery, continence and quality of life (QoL). Continence was defined by no pad or one safety pad. International Consultation on Incontinence Questionnaire (ICIQ), International Index of Erectile Function questionnaire (IIEF-5) and Bladder Cancer Index (BCI) scores were recorded. RESULTS Fourteen male patients were included (median age: 64 years [IQR 54-67]. Median maximal neobladder cystometric capacity was 495 ml [IQR 410-606] and median compliance was 35.5 ml/cm H2O [IQR 28-62]. All patients had post-void residual volume < 30 ml, except for three (22%) who required clean intermittent-self catheterisation. Daytime continence was achieved in 10 patients (71%) and night-time continence in two (14.3%). Median ICIQ score was 7 [IQR 5-11]. Postoperative erectile function was present in 7% of patients (mean IIEF-5 = 5 [IQR 2-7]). Thirteen patients (93%) were satisfied with their choice of neobladder. CONCLUSION RARC with totally intracorporeal orthotopic neobladder for bladder cancer provides satisfactory urodynamic results and good QoL. These findings should be confirmed long-term.

Abstract
Purpose This study aimed to compare the functional and oncological outcomes of females who underwent uterus-sparing radical cystectomy (USRC) and standard radical cystectomy (SRC). Materials and Methods Between February 2009 and December 2020, 90 female patients who underwent radical cystectomy with urinary diversion were included in this study, comprising the USRC and SRC groups. Functional outcomes were assessed in 63 patients who only underwent radical cystectomy with neobladder formation. Questionnaire scores, clean intermittent catheterization (CIC) rate, and urinary continence rate were analyzed. Oncological outcomes were assessed in 86 patients, regardless of the urinary diversion type. Overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS) were compared. Results CIC rate was significantly lower in the USRC group than in the SRC group (14.7% vs. 48.0%; p=0.005). The continence rate was significantly higher in the USRC group than in the SRC group (85.3% vs. 40.0%; p=0.001). There were no significant differences in OS (p=0.890), CSS (p=0.700), or RFS (p=0.270) between the two groups. In multivariate analysis, uterine preservation did not significantly increase the hazard ratio (HR) of OS (HR, 0.62; 95% CI, 0.18–2.11; p=0.450), CSS (HR, 0.99; 95% CI, 0.22–4.40; p=0.990), or RFS (HR, 0.46; 95% CI, 0.19–1.11; p=0.840). Conclusions USRC resulted in higher continence rates and lower CIC rates than SRC without negatively affecting oncological outcomes. Hence, with thorough deliberation, USRC should be considered for females undergoing radical cystectomy.

Abstract
PURPOSE OF REVIEW This article aims to discuss recently published (2019-2021) studies on robot-assisted radical cystectomy (RARC) with attention to evidence comparing intracorporeal (ICUD) and extracorporeal urinary diversion (ECUD) in terms of intraoperative and perioperative metrics. RECENT FINDINGS RARC produces equivalent oncological outcomes compared to open radical cystectomy (ORC). The benefits of RARC are most pronounced perioperatively. ICUD has been increasingly used at centers of excellence as it reduces intestinal exposure, which may incrementally minimize morbidity compared to ECUD or ORC. As the learning curve for ICUD diversion has flattened, retrospective analyses have emerged that suggest this technique may hold benefit over both ORC and RARC with ECUD, though current data is conflicting, and a randomized controlled study is forthcoming. SUMMARY ORC is the current 'gold standard' management for muscle-invasive bladder cancer. Based on the premise of the minimization of perioperative morbidity, the development of RARC, most recently with ICUD, seeks to improve patient outcomes. Despite a protracted learning curve, many expert bladder cancer centers have adopted an intracorporeal approach. As more centers adopt, refine, and climb the learning curve for ICUD, a clearer insight of its effect on morbidity will be revealed-informing further adoption of the technique.
