后腹腔镜手术治疗65例肾囊肿

目的：探讨后腹腔镜肾囊肿去顶术的方法及疗效。方法：65例采用全身麻醉，健侧卧位，经后腹腔途径建立后腹腔操作空间，在腹腔镜监视下，寻找肾囊肿，充分暴露囊肿边缘，肾囊肿中央戳孔，吸除囊液，提起囊壁距肾实质0．5cm切除，常规留置引流管后结束手术，1～2d拔除引流管。结果：65例手术均获成功；手术时间40～120min，平均60min；术中出血10～30ml，平均20ml；术后1、2d下床活动；无术后大出血、漏尿等并发症发生；术后随访3～18个月，B超或CT复查未见囊肿复发。结论：后腹腔镜肾囊肿去顶术疗效明确，具有损伤小、术后恢复快、痛苦小和住院时间短等优点，是一种安全、有效的方法，可作为治疗肾囊肿的首选。

Retroperitoneoscopic surgery for 65 patients with renal cyst

Objective：To explore the techniques and efficacy of retroperitoneoscopic unroofing of renal cyst.Methods：A total of 65 patients were performed general anaesthesia,in position on uninjured side ,established the operational space through retroperitoneal. Looking for the renal cyst under the monitoring of laparoscope, cysts edge were fully exposed, stabbed a hole in the center of the cyst and siphoned out the cyst fluid.All cysts were unroofed 0.5 cm far from renal parenchyma, ended the operation after putting the drainage-tube routinely,and it was pulled out after 1-2 postoperative days.Results ：The operation were successfully accomplished in all patients. The operation time was 40-120 （60） min. The intraoperative bleeding was 10-30 （20） ml, the patients got out of bed after 1-2 days postoperatively. No major haemorrhage, leakage of urine happened postoperatively. Follow up time was 3-18 months. No recurrence was found under B-supersonic or CT.Conclusion：Retropertoneal laparoscopic unroofing is a safe and effective procedure for renal cyst.
