OBJECTIVETo investigate the clinical characteristics, diagnostic methods and minimally invasive treatment of prostatic utricle cyst.

METHODSWe retrospectively analyzed the clinical data of 9 cases of prostatic utricle cyst, of whom 5 presented with frequent or urgent micturition, 3 with difficult urination or thinning urinary stream, and the other 1 with hemospermia. All the cases underwent ultrasonography and MRI. Transurethral cyst deroofing was performed for 3 of the patients with smaller cysts close to the prostatic urethra, and laparoscopic excision of the prostatic utricle was conducted for the other 6 with bigger cysts behind the prostatic urethra.

RESULTSThe duration of transurethral cyst deroofing ranged from 30 to 50 min and intraoperative bleeding was 20 -70 ml; the mean time of laparoscopic excision of the prostatic utricle was 100 - 150 min and intraoperative bleeding was 30 -50 ml. All the patients were followed up for 3 - 12 months, which revealed normal penile erection and ejaculation, and no urinary tract irritation or difficult urination.

CONCLUSIONUltrasonography and MRI are excellent imaging modalities for accurate depiction of prostatic utricle cyst. Transurethral cyst deroofing is valuable for prostatic utricle cyst close to the prostatic urethra. Laparoscopic excision of the prostatic utricle, owing to its safety, effectiveness, minimal invasiveness, fewer complications and rapid recovery, can be used as the first option for the treatment of prostatic utricle cyst.
