目的探讨经皮肾微造瘘输尿管镜取石术治疗肾结石的疗效。方法选择2004年8月至2005年3月经皮肾微造瘘输尿管镜取石治疗肾结石者12例,男7例,女5例;年龄32～69岁,平均45岁。结石长径为0.7～2.5cm,单发性结石4例,多发性结石8例。其中鹿角状结石3例,双肾结石2例,孤立肾并肾结石1例,有开放手术史2例。结果12例均行一期穿刺取石,1次取石11例,2次取石1例;单通道取石10例,双通道取石2例。结石清除率为83%;平均手术时间135min;术中明显出血1例;平均住院12d。结论经皮肾微造瘘输尿管镜取石术具有创伤小、恢复时间短、并发症少等优点,是治疗肾结石的一种有效方式。
Objective To investigate the effect of ureteroscopic lithotripsy on renal calculus in percutaneous nephrostomy. Methods 12 patients (7 males and 5 females) were treated by ureteroscopic ureteroscopic lithotripsy in percutaneous nephrostomy from August 2004 to March 2005. The patients were 32 to 69 years old with an average of 45 years old. The long diameter of stone is 0.7 ~ 2.5cm, solitary stones in 4 cases, multiple stones in 8 cases. Among them, there were 3 cases of antler-like stones, 2 cases of double kidney stones, 1 case of isolated kidney and kidney stones, and 2 cases of open surgery. Results All the 12 cases underwent primary puncture, 11 cases of primary stone and 1 case of secondary stone; 10 cases of single-channel stone and 2 cases of double-channel stone. The stone removal rate was 83%; the average operation time was 135 minutes; the bleeding was obvious in 1 case; the average hospitalization was 12 days. Conclusion Percutaneous nephrostomy with ureteroscopic lithotripsy has the advantages of less trauma, shorter recovery time and fewer complications, which is an effective way to treat kidney stones.
