    Purpose: The results of transurethral marsupialization as treatment for medial prostatic cysts were assessed. Materials and Methods: Between June 1992 and August 1994 we performed transrectal ultrasound on 704 patients with symptoms of bladder outlet obstruction or lower urinary tract symptoms and a medial prostatic cyst was found in 34 (5%). Transurethral marsupialization of the cyst via incision of the prostatic floor under transrectal ultrasound guidance was performed in 18 patients. Followup was 12 to 25 months (mean 18). Results: Patients with a medial prostatic cyst complained of prostatitis-like symptoms (77%), scrotal pain (62%), impaired micturition (32%), small volume ejaculation (35%), painful ejaculation (24%), hemospermia (24%) and infertility (12%). After marsupialization of the cyst, symptoms resolved completely in 14 patients (78%), improved in 17 (94%) and did not improve in only 1 (6%). No complications of this procedure were noted. The 16 patients who did not undergo surgery still complain of prostatitis-like symptoms without evidence of bacterial prostatitis. Conclusions: We believe that a medial prostatic cyst can cause prostatitis-like symptoms and that marsupialization of the cyst can provide symptom relief in the majority of patients.
