Abstract

Urinary incontinence is a major complication following radical prostatectomy. The aim of the present study was to assess the association between urinary continence following laparoscopic radical prostatectomy (LRP) and various factors measured using real‑time intraoperative transrectal ultrasonography (TRUS). Patients (n=53) with localized prostate cancer underwent LRP in combination with real‑time intraoperative TRUS navigation and were evaluated for urinary continence for more than 6 months following LRP. Prostate size, membranous urethral length (MUL) and bladder‑urethra angle were measured using real‑time intraoperative TRUS immediately before and after surgery. Urinary continence was regained by 4, 15 and 27 patients 1, 3 and 6 months after LRP, respectively. Longer postoperative MUL was significantly correlated with recovery of urinary continence 1, 3 and 6 months after LRP. In addition, an increase in difference between preoperative and postoperative MUL was also associated with superior continence. No correlation was observed between postoperative MUL and the rate of tumor‑positive surgical margins. Larger prostate volume was correlated to postoperative continence 6 months after surgery. Shorter operation time and less blood loss resulted in postoperative urinary continence 1 month after LRP. Preoperative MUL, bladder‑urethra angle, age and body mass index had no correlation with urinary continence. Postoperative MUL was the most significant factor for early recovery of urinary continence following LRP. These results indicate that preservation of longer urethra during surgery may be recommended without tumor‑positive surgical margins.
