[A modified cervico-prostatic incision technic in hypertrophic adenoma in young subjects desiring to preserve ejaculation].

The treatment of bladder neck obstruction by transurethral resection of the prostate is responsible for retrograde ejaculation, which is poorly tolerated by our younger patients. Bladder neck incision, initially proposed as treatment for bladder neck sclerosis and for small prostates, was performed according to a modified technique in 36 patients with a mean age of 57.6 years (range: 41-72 years), with benign prostatic hypertrophy less than 30 grams and wishing to retain antegrade ejaculation. This technique consists of creating a deep groove with the resector hook extending from the ureteric orifice to 5 mm above the verumontanum, incising the full thickness of the detrusor and prostatic urethra as far as the retrocervical fat. This preserves a supramontanal ring of urethral muscle whose contraction during orgasm prevents retrograde ejaculation of semen. Resection of the median lobe was also performed in 8 patients, while sparing the cervical muscular ring. The mean follow-up was 2.4 years (range: 4-84 months). Dysuria was very considerably improved in 32 patients (91.5%), with a Madsen score of less than 2. Antegrade ejaculation was preserved in 32 patients (91.5%). Two patients had to undergo secondary prostatic resection because of persistent dysuria (these 2 patients retained antegrade ejaculation). Unilateral bladder neck incision, sparing a supramontanal muscular ring is an easy, rapid technique with low morbidity, effective in the treatment of prostatism due to a small prostate (less than 30 grams). It is the operation of choice in young patients with small prostates who wish to retain antegrade ejaculation.(ABSTRACT TRUNCATED AT 250 WORDS)
