Prostatic Utricle Cysts (Müllerian Duct Cysts)

Abstract

A series of 88 male patients with prostatic utricle cysts (müllerian 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 per cent), while lower obstructive symptoms were noted in 29 per cent. Of the 20 clinical case reports in boys 25 per cent presented 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 fourth. Unilateral renal dysgenesis or agenesis was associated in 10 per cent of the reports. While the suprapubic surgical approach to excision has been used most commonly it has proved unsatisfactory in two-thirds 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 per cent incidence of malignancy in prostatic utricle cysts is noted.
