Large prostatic utricle--unusual cause of urine infection.

A large prostatic utricle is a rare anomaly of the urinary tract. In individuals with scrotal or perineal hypospadia and cryptorchism it occurs even in 34%. The author reports on two children diagnosed for a large prostatic utricle which caused urine infection and obstruction of low urinary tract. The first child with polymalformation syndrome had a bilateral retention of testicles and scrotal hypospadia. The second child with normally developed external genitals was found to have a functionally solitary right kidney with large prostatic utricle of the 3rd grade and cystic dysplasia of the left kidney. The diagnosis was made on the basis of cystourethrography, cytoscopy and sonography. A large prostatic utricle where both gonaducts terminated was removed from the suprapubic retrovesical approach. It was completely removed in the first child and partial resection was made in the second child.
