[The diagnosis and treatment of the Mullerian duct cyst: 48 cases report].

Objective: To study the diagnosis and treatment methods of Mullerian duct cyst.
Methods: The records of 48 patients with Mullerian duct cyst were reviewed and the diagnosis and treatment methods were compared. From January 1993 to December 1997, eight patients visited the clinic, most of whom complained of the chronic prostatitis symptom. They all underwent the transrectal ultrasonography (TRUS). Seven patients were treated by transperineal TRUS-guided aspiration therapy. One patient with the large Mullerian duct cyst was extirpated by open operation. From January 2002 to December 2007, we treated forty patients. Most of them visited us complained of the obstructive azoospermia. All patients were diagnosed by the TRUS and twelve patients underwent MRI examine. Thirty-nine patients with smaller Mullerian duct cyst were treated by transurethral cyst incision therapy. One patient with large Mullerian duct cyst was extirpated by laparoscopic operation.
Results: One of the eight patients, recurrence was detected at the half-year's follow-up and cured by transurethral cyst incision. All the 40 patients underwent TRUS at three months postoperative follow-up, no cysts recurrence. At the six months postoperative follow-up, ten of thirty-nine patients obstructive azoospermia patients had made their wives pregnant successfully. Nine patients of the other twenty-nine patients had sperms in semen. One 19 years old patient's symptom disappeared.
Conclusions: The patient with Mullerian duct cyst often complained of chronic prostatitis symptom and the obstructive azoospermia. TURS was the preferred examine method in the diagnosis of the Mullerian duct cyst. And MRI could offer more exact informations. Transurethral cyst incision was effective methods for Mullerian duct cyst. Laparoscopic Mullerian duct cyst resection was a good choice for the large cysts.
