The aim of the present study is to elucidate pre- and post-operative factors contributing to early recovery of UC after laparoscopic radical prostatectomy (LRP). METHODS A retrospective analysis of 171 consecutive patients who underwent LRP by a single surgeon was carried out. Early recovery of UC was defined as using no pads or one security pad per day within 3 months. Preoperative membranous urethral length (MUL) and postoperative bladder neck angle (BNA) were analyzed to evaluate the relationship with recovery of UC. MUL was measured on coronal images of MRI. BNA was identified by cystogram performed 6 days after surgery. Patients were divided into three groups based on MUL and BNA (Group A: MUL ≥12.1mm and BNA ≥104°, Group B: either MUL ≥12.1mm or BNA ≥104°, Group C: MUL <12.1mm and BNA <104°). RESULTS Among all patients, 63.2% achieved an early recovery of UC. Early recovery rates were 79.4% in patients with MLU ≥12.1mm, 41.9% in patients with MLU <12.1 (p <0.001), and 82.4% in patients with BNA ≥104°, 48.5% in patients with BNA <104° (p <0.001). In the combination of the two parameters, early recovery rates were 94.1%, 60.9%, and 37.3% in group A, B and C respectively (p <0.001). Kaplan-Meire curves of the time to recovery of UC showed significant differences among the three groups (log rank test: p <0.001), (Figure). CONCLUSIONS A combination of preoperative MUL and postoperative BNA was reliable predictor of recovery of UC after LRP. Longer MUL with wider BNA is significantly and positively associated with an early recovery of UC. © 2018FiguresReferencesRelatedDetails Volume 199Issue 4SApril 2018Page: e43 Advertisement Copyright & Permissions© 2018MetricsAuthor Information Takehisa Onishi More articles by this author Takuji Shibahara More articles by this author Syou Sekito More articles by this author Takeshi Sasaki More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
