[Acute urinary retention caused by intraprostatic cysts: diagnostic and therapeutic role of transrectal prostatic echography]

: There are two type of congenital prostatic cyst, the mullerian duct cyst and the utricular cyst. They are not common and rarely symptomatic. We report a 16-year-old male who presented with acute urinary retention and a 3-month history of urine stream diminished in force and reduced sperm volume. Transrectal ultrasonography showed a prostatic cyst in the midline near the seminal colliculus. Transperineal aspiration of the cyst resulted in return to normal miction and sperm volume.
