Abstract

Purpose

This retrospective comparative study aims to evaluate the safety and efficacy of a novel periurethral structural reinforcement (PSR) technique for enhancing early urinary continence recovery after laparoscopic radical prostatectomy (LRP).

Methods

Clinical records of 140 prostate cancer patients undergoing LRP between March 2022 to August 2023 were reviewed. Participants were divided into modified (PSR) and conventional (standard anastomosis) groups. The PSR technique augments standard posterior reconstruction by incorporating circumferential support sutures, aimed at reconstructing key surgical-damaged periurethral supports. Continence status (≤1 pad/day) were analyzed at catheter removal, 1, 2 4, and 12 weeks following surgery. Operative time, complications and pathologic characteristics were compared between 2 groups.

Results

Baseline characteristics were comparable among 2 groups. The modified group maintained superior continence recovery at all time intervals: 16.0% vs. 0% (immediate, P < 0.001), 20.0% vs. 6.7% (1 week, P = 0.018), 52.0% vs. 27.8% (4 weeks, P = 0.004), and 82.0% vs. 52.2% (12 weeks, P < 0.001), respectively. Complication rates showed no significant difference (P > 0.05).

Conclusion

The PSR technique is a safe and simple technique to accelerate early urinary continence recovery following LRP. Nevertheless, the generalizability of these outcomes require rigorous validation through a large-scale multicenter randomized controlled trial.

尿道周围结构加固技术对腹腔镜根治性前列腺切除术后早期尿失禁恢复的影响：一项回顾性研究

目的本回顾性比较研究旨在评价一种新型尿道周围结构强化（PSR）技术在腹腔镜根治性前列腺切除术（LRP）后早期尿失禁恢复中的安全性和有效性。方法回顾性分析2022年3月至2023年8月140例前列腺癌患者行LRP手术的临床资料。参与者分为改良吻合（PSR）组和常规吻合（标准吻合）组。PSR技术通过结合环支持缝合线来增强标准后路重建，旨在重建手术损伤的关键尿道周围支持。在拔管、术后1、2、4、12周分析尿失禁情况（≤1垫/天）。比较两组手术时间、并发症及病理特点。结果两组患者基线特征具有可比性。改良组在所有时间间隔均保持较好的尿失禁恢复：16.0% vs. 0%（即刻，P < 0.001）， 20.0% vs. 6.7%(1周，P = 0.018), 52.0% vs. 27.8%(4周，P = 0.004), 82.0% vs. 52.2%（12周，P < 0.001）。并发症发生率无显著差异（P > 0.05）。结论PSR技术是一种安全、简便的加速LRP术后早期尿失禁恢复的技术。然而，这些结果的普遍性需要通过大规模多中心随机对照试验进行严格验证。

期刊介绍： Urologic Oncology: Seminars and Original Investigations is the official journal of the Society of Urologic Oncology. The journal publishes practical, timely, and relevant clinical and basic science research articles which address any aspect of urologic oncology. Each issue comprises original research, news and topics, survey articles providing short commentaries on other important articles in the urologic oncology literature, and reviews including an in-depth Seminar examining a specific clinical dilemma. The journal periodically publishes supplement issues devoted to areas of current interest to the urologic oncology community. Articles published are of interest to researchers and the clinicians involved in the practice of urologic oncology including urologists, oncologists, and radiologists.
