From Jan. l985 to June 1990, 1O9 cases with hypospadias, five with male pseudohermaphroditism and four with true hermaphroditism have been studied radiologically in order to evaluate the incidence and configuration or prostatic utricle or vagina masculinus at Pusan National University Hospital. The results were as follows :. 1. The prostatic utricle or vagina masculinus, was found 27 cases (24.8%) out of 109 hypospadias. all of male pseudohermaphroditism and true hermaphroditism. 2. The prostatic utricle was found in 2 (l8.2%) out of 11 glandular hypospadias. 11 (l9.6%) out of 56 penile hypospadias, 12 (34.3%) out of 35 penoscrotal hypospadias and II (68.8%) out o 16 perineal hypospadias. 3. According to Ikoma's classification of prostatic utricle, grade 0, I, II, and III were 1 case (2.1%), 13 (36.1%). 7 (19.4%) and 15 (41.7%), respectively. The incidence and size of prostatic utricle increased according to the severity of hypospadias. 4. Most cases were asymptomatic. Irritative symptoms in bladder or urethra were noted in 4 cases ( 11.1%), and recurrent epididymitis in 3 (8.3%). 5. Of 3 cases with recurrent epididymitis, one had excision of the prostatic utricle. Of 5 male pseudohermaphroditism. 2 vagina masculinus were removed with simultaneous urethroplasty of 4 true hermaphroditism, vaginoplasty was done in 1 case and the removal of vagina masculinus and urethroplasty were done in 2 cases. Therefore. the voiding cystourethrography or retrograde urethrography is necessary for diagnosis of prostatic utricle. especially in cases of severe degree of hypospadias, hermaphroditism and recurrent epididymitis with uncertain causes.
