Abstract:
Reviewing the radiologic studies of the 402 patients with infravesical obstructive lesions, we studied the pattern of upper urinary tract change in children and adults. The following results were obtained. 1. The upper tract dilatation was shown in 68 patients : 9 of 11 posterior urethral valve patients(82 percent), 22 of 280 benign prostatic hyperplasia patients(7.9 percent), 11 of 57 urethral stricture patients(19 percent), 26 of 54 neurogenic bladder patients(48 per cent). 2. Upper tract dilatation in infravesical obstructive diseases occurred on one side in 32 percent of the cases : 24 percent in children and 38 percent in adults. 3. Of 68 patients with upper tract dilatation, 40 patients had voiding cystourethrography. Vesicoureteral reflux was observed in 30 of 69 dilated kidney units : 25 of 49 kidney units (51 percent) in children and 5 of 20 kidney units(25 percent) in adults. Vesicoureteral reflux was more frequently occurred in children than in adults.
