Ectopic opening of vasa deferentia into a prostatic utricle cyst

Prostatic utricle cysts result from incomplete regression of the Müllerian duct remnant or decreased androgenic stimulation of the urogenital sinus. Children usually present with urinary tract infections (UTIs), irritative symptoms and urine retention, although some cases are asymptomatic. These cysts sometimes can cause a palpable abdominal mass, urethral discharge, terminal hematuria and recurrent epididymitis. A high incidence of such cysts is seen in boys with hypospadias, especially the more proximal types.
