直肠癌及腹膜后肿瘤术中输尿管支架置入预防泌尿系并发症

目的：探讨在高手术难度直肠癌及腹膜后肿瘤术中联合膀胱镜下输尿管支架置入预防泌尿系并发症的临床价值。方法9例高手术难度直肠癌及腹膜后肿瘤患者手术前均在膀胱镜下行单侧或双侧输尿管支架置入，复发性直肠癌、新辅助放化疗后直肠癌、后腹膜肿瘤均行R0或R1切除，晚期直肠癌伴梗阻行R2切除。术后3个月门诊膀胱镜下取出支架。结果术中均未发生输尿管切断、损伤、误扎，膀胱损伤，术后均未发生尿瘘、输尿管狭窄等并发症。结论高手术难度直肠癌及腹膜后肿瘤术中先行膀胱镜下输尿管支架置入简单易行，且对于预防泌尿系并发症有重要意义。

Cystoscopic Ureteral Stent Placement the Prevention of Urinary Complications After Operation of Rectal Cancer and Retroperitoneal Tumor

Objective To investigate the clinical value of intraoperative cystoscopic ureteral stent placement in the prevention of urinary complications of rectal cancer and retroperitoneal tumor treated with high difficulty opera-tion. Methods Nine cases of rectal carcinoma and retroperitoneal tumor treated with high difficulty operation re-ceived the intraoperative cystoscopic ureteral stent placement,recurrent rectal cancer,rectal cancer after neoadjuvant chemoradiotherapy and retroperitoneal tumor were executed the R0 or R1 resection,advanced rectal cancer with intes-tinal obstruction were executed the R2 resection. Cystoscopic ureteral stent was taken out in the three months after operation. Results There was no ureteral injury and bladder injury in operation,there was no urinary fistula and u-reteral stricture after operation. Conclusion Cystoscopic ureteral stent placement was simple and easy,can be used in the prevention of urinary complications rectal cancer and retroperitoneal tumor treated with high difficulty opera-tion.
