幼小婴儿肾盂输尿管连接部梗阻治疗体会

目的32例幼小婴儿肾盂输尿管连接部梗阻诊断和治疗方法。方法回顾性分析了32例平均年龄51．5d的幼小婴儿肾盂输尿管连接部梗阻的诊断和治疗。结果32例患儿术后恢复良好，但其中出现尿外渗2例；吻合口狭窄1例，因周围粘连和瘢痕压迫吻合口而被迫重新二次手术。于术后1个月、3个月、6个月、1年、2年分别行B超检查，均未再出现肾盂增大，未出现肾盂肾盏分离加大趋势，证实吻合口通畅。结论产前和产后的B超检查是比较可靠的辅助手段，对产前肾积水胎儿，建议产后7～10d首次常规B超检查，并于生后6周继续复查；如果B超观察肾盂未再继续扩张，可继续观察；反之，则应积极手术治疗，以防止影响肾功能；小儿肾积水一般均应考虑保留肾脏，肾皮质在2mm以上，肾脏无明显发育异常，应争取保存患肾；离断性肾盂输尿管成形术效果最好；同时应该积极进行术后随访。

Surgical management of neonatal ureteropelvic junction obstruction

Objective To review our experience in the management of neonatal ureteropelvic junction obstruction. Methods Medical records of 32 patients were retrospectively analyzed. Results The mean age of the patients was 51.5 days. Two patients developed urine leak and one developed anastomotie stenosis which required two further operations. Patients were follow up with ultrasonography one,three,and six months after the operation. No further renal pelvic dilation was detected. Conclusions If renal pelvis dilation were detected, surgical intervention is recommended.
