目的：探讨腰部小切口离断性肾盂成形术治疗婴幼儿肾盂输尿管连接部梗阻的临床疗效。方法选取我院2009年10月至2013年10月间收治的220例肾盂输尿管连接部梗阻患儿作为研究对象，按治疗方式分为两组各110例，研究组采用腰部小切口离断性肾盂成形术进行治疗，对照组采用腰部常规切口离断性肾盂成形术进行治疗。随访1年，比较两组患儿的临床疗效。结果两组的治疗总有效率、手术时间以及术中出血量比较无统计学差异（P>0.05)。研究组的手术切口长度显著短于对照组，家属满意度显著高于对照组（P<0.05)。研究组近期并发症的总发生率为6.36%，显著低于对照的18.81%（P<0.05)。结论采用腰部小切口离断性肾盂成形术治疗婴幼儿肾盂输尿管连接部梗阻和常规切口一样安全有效，而且手术切口更小，美容效果更佳。%Objective To explore the clinical effect of dismembered pycloplasty with lumbar small incision for the treatment of ureteropelvic junction obstruction of infants. Methods A total of 220 cases of infants with ureteropelvic junction obstruction admitted to our hospital from October 2009 to October 2013 were selected and divided into two groups equally according to the treatment methods. The study group received dismembered pycloplasty with lumbar small incision, while the control group received dismembered pycloplasty with lumbar routine incision. All cases were followed up for 1 year, and the curative effects were compared. Results No statistical difference was found between two groups in the total effective rate, operation time, and intraoperative blood loss (P>0.05). The incision length of study group was significantly shorter than that of control group, and the relatives' satisfaction degree was significantly higher than that of control group (P<0.05). The total incidence rate of recent complications of study group was 6.36%, significantly lower than 18.81%of control group (P<0.05). Conclusions Dismembered pycloplasty with lumbar small incision is safe and effective as routine incision for the treatment of ureteropelvic junction obstruction of infants;in addition, it has smaller surgical incision, and better cosmetic effect.
