Ectopic Ureter Associated with Congenital Hypoplasia of the Kidney / 대한비뇨기과학회지

ABSTRACT

A 14-year old girl presented with urinary incontinence along with normally secured voluntary voiding. Careful physical examination revealed leakage of urine through a small opening near the vestibule, ventral to the urethral meatus. Cystoscopically, the right ureteral orifice was absent but otherwise normal. Nonfunctioning right kidney was found on excretory urography. A #4 ureteral catheter was inserted into the ectopic opening as high as 10cm, and the retrograde pyelogram showed dilated right ureter ending blindly at the level of lumber vertebra II with stricture at the level of the tip of the catheter. After the right nephroureterectomy, she became dry and was discharged on the 12th postoperative day. The removed kidney weighed only 8 Gm. and pathological diagnosis was congenital hypoplasia of the right kidney with ectopic ureteral opening.
