興味ある走行を示した尿管異所開口の1例

Abstract

A 3-year-old female was seen with a chief complaint of urinary incontinence. Remarkable filling defect of the bladder neck was revealed on radiological studies. It was found that the lower part of the left ectopic ureter was markedly dilated before passing behind the bladder and that the ureter drained into right side of the urethra. The filling defect was found due to dilated ureter. She received a total nephroureterectomy. The extirpated kidney weighed only 6 grams and histology showed hypoplasia. According to Thom's classification, this case was classified into type 1. Discussions were made on our 4 other cases in reference to other literatures.
