目的:探讨超微经皮肾镜取石术(SMP)治疗上尿路结石的临床效果。方法:2015年8月~2016年3月采用SMP对13例上尿路结石患者进行手术治疗,其中鹿角形结石1例,肾下盏结石3例,肾盂结石5例,输尿管上段结石3例,多发性肾结石1例;结石直径1.1~2.4cm,平均(1.7±0.2)cm。结果:11例行单通道SMP,2例行双通道SMP,其中应用于复杂性肾结石二期手术3例;手术时间9~150min,平均(34±22)min;术中出血量平均(14±5)ml,无需要输血的患者;术后未出现发热病例。平均住院时间2d。结论:SMP治疗上尿路结石安全,创伤小,术后恢复快,住院时间短。
Objective: To investigate the clinical effect of ultra-micro percutaneous nephrolithotomy (SMP) on upper urinary calculi. Methods: From August 2015 to March 2016, 13 cases of upper urinary tract calculi were treated by SMP. Among them, 1 was staghorn stone, 3 was lower calyx stone, 5 was renal pelvis, 3 was upper ureteral stone, One case of multiple renal stones; stones 1.1 ~ 2.4cm in diameter, an average of (1.7 ± 0.2) cm. Results: Eleven patients underwent single-channel SMP and 2 patients underwent dual-channel SMP, of which 3 cases were complicated with secondary renal calculi. The operation time ranged from 9 to 150 minutes (mean, 34 ± 22) min. The mean intraoperative blood loss ± 5) ml, no need for transfusion of blood; no cases of fever after surgery. The average length of stay 2d. Conclusion: SMP is safe and has less trauma to the upper urinary tract stones, faster recovery and shorter hospital stay.
