Retropubic prostatectomy for giant benign prostatic hyperplasia.

Giant benign prostatic hyperplasia is a rare pathology of the prostate gland. Here we report the successful removal of the ninth largest prostate ever reported. This 65-year-old patient presented with acute urinary retention secondary to a bulky left prostatic mass identified on pelvic magnetic resonance imaging (MRI). His preoperative prostate-specific antigen (PSA) value was 44 ng/mL; preoperative biopsies were negative for malignancy. Open radical retropubic prostatectomy was performed and the resulting prostatic mass was measured at 13.5 cm x 11.5 cm x 5.2 cm, weighing 708 g including the prostate. The patient tolerated the procedure well. Surgical pathology showed no evidence of malignancy.
