Abstract: Background: Prostate cancer is a common malignant tumor in the male urogenital system, and laparoscopic radical prostatectomy (LRP) is the standard surgical procedure for early-stage patients. However, postoperative urinary incontinence remains a major complication. The membranous urethra and its surrounding sphincters play a critical role in urinary continence, but the impact of their preserved length on postoperative recovery of urinary continence function remains unclear. Objective: To investigate the effect of the preserved length of the membranous urethra during LRP on early and long-term recovery of urinary continence function in patients. Methods: A retrospective analysis was conducted on 160 patients who underwent LRP from March 2023 to June 2024. The patients were divided into a long-segment group (preserved length ≥15 mm, 90 cases) and a short-segment group (preserved length <15 mm, 70 cases) based on the preserved length of the membranous urethra. The International Continence Society criteria were used to evaluate the urinary continence recovery rate (≤1 pad/day) at 1, 3, 12, and 24 months postoperatively, and differences between the two groups were compared. Results: < 0.05). Conclusion: Preserving the length of the membranous urethra ≥15 mm during LRP can significantly promote the recovery of early and long-term urinary continence function, providing a basis for precise surgical operations in clinical practice. Future studies with larger sample sizes and longer follow-up periods are needed for validation.
