Introduction: To compare surgical, oncologic, functional outcomes and complication rate between intracorporeal neobladder (ICNB) and extracorporeal neobladder (ECNB) orthotopic ileal neobladder of robot-assisted radical cystectomy (RARC) in patients with nonmetastatic bladder carcinoma (BC). Materials and Methods: From 2014 to 2019, we prospectively collected and retrospectively analyzed 101 patients with nonmetastatic BC treated with RARC and ortothopic neobladder. Chi-squared test estimated differences in proportions of functional and oncologic outcomes. Multivariable logistic regression models (MLRMs) focused on overall, early (<30 days from discharge), and late complication rate (>30 days from discharge) in ICNB vs ECNB. Results: Of all patients, 57 (56.4%) ICNB and 44 (43.6%) ECNB patients were identified. At least one complication occurred in 75.4% vs 72.7% in ICNB vs ECNB, respectively (p = 0.9). In MLRMs, focusing on complication rate, there was no statistically significant difference between ICNB vs ECNB for overall (p = 0.8), early (p = 0.6), and late complications (p = 0.8). No statistically significant differences were recorded for tumor relapse rate, cancer-specific and other cause mortality. No positive surgical margins were recorded in both groups. Daytime and nighttime continence recovery were 89.4% vs 87.1% (p = 1.0) and 63.8% vs 51.6% (p = 1.0) for ICNB vs ECNB. Potency recovery was 59.1% vs 54.3% (p = 0.5) for ICNB vs ECNB. Conclusions: No statistically significant differences in complication rate (overall, early, or late) were identified, when ICNB and ECNB were compared. Similarly, no statistically significant difference was found in oncologic and functional outcomes.

Abstract

Introduction: To compare surgical, oncologic, functional outcomes and complication rate between intracorporeal neobladder (ICNB) and extracorporeal neobladder (ECNB) orthotopic ileal neobladder of robot-assisted radical cystectomy (RARC) in patients with nonmetastatic bladder carcinoma (BC). Materials and Methods: From 2014 to 2019, we prospectively collected and retrospectively analyzed 101 patients with nonmetastatic BC treated with RARC and ortothopic neobladder. Chi-squared test estimated differences in proportions of functional and oncologic outcomes. Multivariable logistic regression models (MLRMs) focused on overall, early (<30 days from discharge), and late complication rate (>30 days from discharge) in ICNB vs ECNB. Results: Of all patients, 57 (56.4%) ICNB and 44 (43.6%) ECNB patients were identified. At least one complication occurred in 75.4% vs 72.7% in ICNB vs ECNB, respectively (p = 0.9). In MLRMs, focusing on complication rate, there was no statistically significant difference between ICNB vs ECNB for overall (p = 0.8), early (p = 0.6), and late complications (p = 0.8). No statistically significant differences were recorded for tumor relapse rate, cancer-specific and other cause mortality. No positive surgical margins were recorded in both groups. Daytime and nighttime continence recovery were 89.4% vs 87.1% (p = 1.0) and 63.8% vs 51.6% (p = 1.0) for ICNB vs ECNB. Potency recovery was 59.1% vs 54.3% (p = 0.5) for ICNB vs ECNB. Conclusions: No statistically significant differences in complication rate (overall, early, or late) were identified, when ICNB and ECNB were compared. Similarly, no statistically significant difference was found in oncologic and functional outcomes.
