本研究的目的是探讨腹腔镜前列腺癌根治术中腹腔镜侧精囊入路保留膀胱颈的效果。我们回顾性分析了2020年9月至2022年12月在我机构接受治疗的T1-T3b期前列腺癌患者。腹腔镜侧精囊入路。我们记录了导管拔除后1周、1个月和3个月的膀胱颈保留成功率、膀胱尿道吻合时间、导尿管拔除时间、住院时间和泌尿控制评分，包括尿垫的使用情况。不良事件包括直肠损伤、膀胱损伤、输尿管损伤和手术切缘阳性。56例患者（平均年龄70±5.8岁）膀胱颈保留成功率为100%。膀胱尿道吻合术的中位时间为 11 (9-14) 分钟。术后住院时间中位数为 10 (9-11) 天。 1周尿失禁率为83.9%（47/56），1个月尿失禁率为89.3%（50/56），3个月尿失禁率为98.2%（55/56）。 1例患者因双侧精囊受侵而发生粘连，损伤直肠壁。腹腔镜前列腺癌根治术中，腹腔镜侧精囊入路可完整保留膀胱颈，改善术后尿失禁，即刻尿失禁率高，且显着改善患者的生活质量。

The purpose of this study was to investigate the effect of laparoscopic lateral seminal vesicle approach to preserve the bladder neck during laparoscopic radical prostatectomy.Between September 2020 and December 2022, we retrospectively analyzed patients with T1-T3b stage prostate cancer treated at our institution using the laparoscopic lateral seminal vesicle approach. We recorded the bladder neck preservation success rate, cystourethral anastomosis time, urinary catheter extraction time, length of hospital stay, and urinary control scores, including urine pad use, at 1 week, 1 month, and 3 months post-catheter removal. Adverse events included rectal injury, bladder injury, ureteral injury and positive surgical margins.There were 56 patients (mean age 70 ± 5.8 years) The success rate of bladder neck preservation was 100%. The median cystourethral anastomosis time was 11 (9-14) minutes. The median postoperative hospital stay was 10 (9-11) days. The urinary continence rate was 83.9% (47/56) in 1 week, 89.3% (50/56) in 1 month and 98.2% (55/56) in 3 months. One patient developed adhesions caused by invasion of both seminal vesicles, which damaged the rectal wall.The laparoscopic lateral seminal vesicle approach can preserve the bladder neck completely during laparoscopic radical prostatectomy, improving postoperative urinary continence, with a high rate of immediate urinary continence, and significantly improving patients' quality of life.
