Impact of Urethra-Preserving Surgery During Radical Cystectomy: An Optimal Urethral Management in the Robotic Era
Objectives
The optimal indication and survival benefits of prophylactic urethrectomy (PU) during radical cystectomy remain unclear. Therefore, this study aims to evaluate the impact of urethra-preserving surgery (UPS) on oncological outcome including its recurrence patterns, and to establish an optimal urethral management strategy with a novel UPS technique in the robotic era.
Patients and methods
We retrospectively analyzed 281 male patients with bladder cancer who received radical cystectomy (RC) (115 with and 166 without PU) at our institutions between 2010 and 2023. Subsequently, perioperative and oncological outcomes were assessed between propensity score-matched cohorts.
Results
Urethral recurrence (UR) occurred in 5 patients (5/166, 3.0%), all of whom underwent open-RC. Three among those (1.8%) with concomitant metastasis were died of cancer. There were no statistically significant differences between the PU and UPS groups in urethral-recurrence free survival (urethral-RFS) (P = .14), local-RFS (P = .59) and overall survival (OS) (P = .84) in the entire cohort. However, the UPS group showed significantly worse urethral-RFS (P = .008), local-RFS (P = .005) and OS (P = .03) in patients with high-risk of UR. Analysis of recurrence patterns revealed that UPS in high-risk patients significantly increased local recurrence (25.8% vs. 5.0%, P = .02). Conversely, a novel robotic-UPS technique demonstrated significantly favorable perioperative outcomes, comparable local-RFS (P = .79) and OS (P = .16) without UR (0/134, 0%) when compared to robotic-PU. Robotic-UPS also exhibited significantly better local-RFS (P =.007) and OS (P < .001) than open-UPS.
Conclusions
UR-related death was rare and PU did not show a survival benefit for the entire cohort. However, inappropriate UPS in patients at high-risk of UR may increase local recurrence which might be responsible for poor survival after UPS rather than disease progression derived from UR. The robotic-UPS has the potential to reduce unnecessary PU, urethral and local recurrence without compromising survival.
