腹腔镜下前列腺癌根治术联合保留最大尿道长度和膀胱颈的尿道重建术治疗高危前列腺癌的早期控尿和控瘤效果

Laparoscopic surgery for high-risk prostate cancer:urinary and oncologic outcomes of vesicourethral anastomosis with maximal urethral length and bladder neck preservation

目的探讨联合施行保留最大尿道长度(MULP)和膀胱颈(BNP)的尿道重建术与腹腔镜下前列腺癌根治术(LRP)或机器人辅助腹腔镜下前列腺癌根治术(RALP)治疗高危前列腺癌(HRPC)的早期控尿及控瘤效果。方法回顾性分析上海交通大学医学院附属第六人民医院泌尿外科2022年5月—2024年1月收治的23例HRPC患者的临床资料,所有患者均行LRP(包括RALP),并采用联合MULP和BNP的尿道重建技术。收集并分析患者的术前基线资料包括年龄、身体质量指数、临床T分期、Gleason评分、前列腺重量和体积、前列腺特异性抗原;术中变量包括手术方式、手术时间、术中出血量和术中输血患者数;术后变量包括住院时间、尿管留置时间、切缘阳性数、生化复发数、并发症发生率及术后早期尿控率。结果所有患者均顺利完成手术,无中转开放。手术时间(108±31)min,出血量(112±45)mL,无患者术中输血,住院时间(5.5±1.5)d,尿管留置时间(12.6±1.8)d。术后拔除尿管即刻及1、3、6个月的控尿率分别为39.1%、65.2%、73.9%和91.3%。术后2例患者切缘阳性,均为血管神经束切缘。术后无患者出现尿路梗阻或尿瘘等手术相关并发症。结论联合MULP和BNP的尿道重建术在HRPC患者行LRP治疗中可在不增加控瘤风险的前提下,有效提高患者的早期控尿率,改善患者的术后生活质量。

Objective To explore the application value of vesicourethral anastomosis with maximal urethral length preservation(MULP)and bladder neck preservation(BNP)in laparoscopic radical prostatectomy(LRP)or robot-assisted laparoscopic radical prostatectomy(RALP)for high-risk prostate cancer(HRPC)in terms of early urinary continence and oncology.Methods Clinical data of 23 HRPC patients who underwent LRP(including RALP)with MULP and BNP in our hospital during May 2022 and Jan.2024 were retrospectively analyzed.Patients'basic information,surgical parameters,postoperative complications,oncological outcomes and urinary incontinence were collected and analyzed.Results All operations were completed successfully without conversion to open surgery.The operation time was(108±31)min,average blood loss(112±45)mL,hospital stay(5.5±1.5)days,urethral catheterization time(12.6±1.8)days,and no patient received blood transfusion during operation.The urinary continence rates at the time of catheter removal,and at 1,3,and 6 months after surgery were 39.1%,65.2%,73.9%,and 91.3%,respectively.Two patients had positive margins,both of which were at the neurovascular bundle.No patient developed surgery-related complications,urinary obstruction or fistula after surgery.Conclusion Vesicourethral anastomosis with MULP and BNP in LRP for HRPC can effectively improve patients"early urinary continence rate and postoperative quality of life without increasing the oncological risk.
