Abstract
A series of 88 male patients with prostatic utricle cysts (Muellerian duct) has been compiled by adding our 3 patients to 85 cases reported. Irritative lower urinary tract symptoms were the most common presenting complaint (42%), while lower obstructive symptoms were noted in 29%. Of the 20 clinical case reports in boys 25% with epididymitis often in an undescended gonad. A cystic rectal mass found in half of the patients represents the most common presenting sign, while hypospadias occurred in a 4th. Unilateral renal dysgenesis or agenesis was associated in 10% of the reports. While the suprapubic surgical approach to excision has been used most commonly it has proved unsatisfactory in 2/3 of the cases. The posterior approach was used successfully in 2 boys with preservation of erectile potency in both. The wide spectrum of histopathology of these cysts prevents clear characterization. A 3% incidence of malignancy in prostatic utricle cysts is noted.
