Of 101 antegrade pyelography and/or percutaneous nephrostomy procedures performed within a 6-year period, 18 involved patients less than 6 months of age. The procedures in this age group were characterized by ease of performance -without sedation in the neonates and with sedation in the children -and by the use of smaller needles and catheters. The procedures enabled differentiation between obstructed and nonobstructed dilated systems with pressure-flow studies, depiction of the intimate anatomy of complicated urologic abnormalities, temporary drainage, decompression of pyonephrosis, endourologic access, and collection of urine for cultures after ureterosigmoidostomy. The procedures were highly successful and had few complications.
在6年期间进行的101例顺行肾盂造影和/或经皮肾造瘘手术中，有18例涉及6个月以下的婴儿。该年龄组的手术特点是操作容易——新生儿无需镇静，儿童需镇静——且使用较小的针和导管。这些手术通过压力-流量研究能够区分梗阻性和非梗阻性扩张系统，描绘复杂泌尿系统异常的精细解剖结构，进行临时引流、肾积脓减压、腔内泌尿外科通路建立以及输尿管乙状结肠吻合术后尿液采集培养。这些手术非常成功，并发症很少。
