Abstract: Objective: To evaluate the surgical efficacy of the modified Madigan prostatectomy for prostatic hyperplasia (BPH). Methods: A retrospective analysis of 22 patients with BPH was conducted and the method and the feature of the operation were described. Results: One patient needed urethral repair in 3 patients with urethral injury and the other 19 patients had no urethral injury. One patient needed blood transfusion with the intraoperative blood loss of 950 ml. The blood loss in the other 21 patients ranged from 100 to 650 ml and no blood transfusion were needed in the operation. The operating time was between 60 and 120 minutes. Follow-up examinations for 2 to 14 months showed that no antegrade ejaculation, incontinence, urethral stricture or impotence occurred. Conclusions: The modified Madigan prostatectomy has the advantages such as the less postoperative bleeding, faster recovery, less complications and hospitalization time. It is an ideal open operation procedure.
