预置双J管对宫颈癌手术及放疗中输尿管的保护作用

目的探讨预置双J管防治宫颈癌手术及放疗过程中输尿管损伤的作用。方法回顾性分析80例妇科宫颈癌手术患者术前给予膀胱镜下输尿管逆行插管留置双J管并保留至宫颈癌术后放疗结束的临床资料，一般3个月左右在膀胱镜下更换双J管，需要时可保留至6个月后拔除。与60例宫颈癌未预置双J管的资料进行对比。结果所有手术患者术中均能容易辨认输尿管，损伤输尿管2例（2．50％），对照组因组织粘连等原因不易辨认输尿管，损伤9例（15．00％），两组比较差异具有统计学意义（P〈0．05）；放疗后两组比较，研究组损伤1例，对照组2例，两组比较差异无统计学意义（P〉0．05）。7例晚期肿瘤患者压迫一侧输尿管导致该侧完全梗阻无尿，另一侧部分梗阻，肾功能下降，行双J管引流后1周内肾功能均正常或接近正常。结论输尿管逆行插管预置双J管能够有效预防宫颈癌术中输尿管的损伤。

Prevention of ureteral injury in cervical cancer operation and radiotherapy by pre-setting double J stent

Objective To investigate prevention of ureteral injury in cervical cancer operation and radiotherapy by retrograde double J stent.Methods Data of ureteral injury in 80 cervical cancer operations were reviewed retrospectively.With ureteral stent guided by cystoscope,retrograde double J stent was performed before operation (study group).Results The operations in 80 cases were completed successfully.There were two cases of ureteral injury.The incidence rate of ureteral injury in study grop was significantly lo...
