Transurethral resection of the prostate is the most common technique for the treatment of benign prostatic enlargement. The inconveniences of prostatic resection are retrograde ejaculation and bladder neck stenosis in small prostates. A randomized prospective trial was done to compare the results of conventional transurethral resection of the prostate in 22 patients and urethrotomy of the prostatic urethra in 27 with respect to postoperative retrograde ejaculation, persistent urinary symptomatology and maximal flow rates. After a mean followup of 25 months we concluded that internal urethrotomy of the prostatic urethra is the operation of choice in patients with a prostate of up to 30 gm.144918-20
