REPORT

S.V. (#72-30-37), a 3 yr old white male, was evaluated at Arkansas Children’s Hospital of a recurrent urinary tract infection. He was known to have a completely duplex urethra

because and was

thought to have duplication of the corpora cavernosa also. These findings have been previously rep0rted.l Previous voiding cystourethrography had not demonstrated vesicoureteral reflux. Because of the recurrent bacteriuria. the examination was repeated. Right-sided vesicoureteral reflux was demonstrated. To assess the character of the right ureteral orifice. endoscopy of the lower urinary tract was accomplished. A firm. pink-colored polyp measuring 3 x 5 mm was noted on the dorsal wall of the anterior urethra approximately 4 cm distal to the sphincter. The polyp was not friable. The remainder of the urethra demonstrated no abnormalities. In retrospect, the polyp could be recognized on both the antegrade and retrograde urethral studies (Figs. I and 2). The
