Comparison in Efficacy of Periurethral Reconstruction Leading to Urinary Continence Improvement After Robot-assisted Radical Prostatectomy.

Purpose: This study was designed to evaluate the efficacy of different periurethral structural reconstruction approaches to improve postoperative continence post robot-assisted radical prostatectomy (RARP), which remains a critical concern.
Methods: This study included patients with prostate cancer who received single, combined, and nonreconstruction following RARP from April 2017 to May 2021. Medical details were recorded, and patients were followed up via phone or the outpatient clinic. Continence, potency recovery, and quality of life were evaluated. Continence rate was assessed by daily urinary pads use and was compared between groups with the Kaplan-Meier method. Potency recovery was assessed by the questionnaire score. All variables were further analyzed via univariable and multivariable regression analysis.
Results: Sixty patients were included in nonreconstruction group. Fifty-two and 156 patients were included in the single and combined group, respectively. Across early postoperative follow-up period, both single and combined reconstruction group showed higher continence rate (p < 0.05). The combined approach showed an advantage over the single one in improving continence rate (p < 0.05). Univariable and multivariable regression analysis point to the reconstruction approach as an independent factor that affects postoperative continence recovery post RARP.
Conclusions: Periurethral reconstruction approaches were found to be beneficial in promoting early continence recovery after RARP, without compromising preserved neurovascular bundle. Combination of anterior and posterior reconstruction could be more beneficial on continence recovery and should be considered in clinical practice.
