微创经皮肾技术治疗单纯性肾囊肿18例

Percutaneous Renal Techniques for Simple Renal Cysts:A 18-case Report

目的：探讨经皮肾技术处单其纯性肾囊肿的疗效和安全性。方法：2001年8月至2004年7月对本科住院单纯肾囊肿18例患者采用经皮肾技术处理，囊肿平均直径为6cm。其中采用经皮穿刺囊肿、输尿管镜下电切外壁（直接法）治疗10例；采用微创经皮肾输尿管镜下囊壁切开内引流（间接法）治疗8例。结果：手术均成功，囊肿处理时间5—25min，无严重并发症发生。平均随访16个月，直接法2例、间接法3例有原囊肿复发。结论：微创经皮肾技术是处理单纯性肾囊肿安全、有效的方法。

Objective：To summarize on the experience of percutaneous renal techniques in treating simple renal cysts. Methods： From August 2001 to July 2004, 18 cases of simple renal cysts were treated with percutanous renal techniques, 10 cases by direct approach with percutanous resection of cysts and 8 cases by indirect approach in which the wall of cyst abutting the collecting system was cut and marsupialized into the renal pelvis, Results： The operations were successful in all of the cases. The duration of cyst managing ranged from 5 to 25 minutes, and no severe complications occurred, At a mean follow-up of 16 months, relapsed cysts were found in 2 cases with direct approach and in 3 cases with indirect approach. Conclusions： Percutaneous renal techniques for simple renal cysts are safe and effective. Direct approach managing the dorsal cysts is easy and reliable, and indirect approach seems suitable for the ventral or peripelvie cysts complicated with stones.
