Preservation of anterograde ejaculation after transurethral resection of both the prostate and bladder neck.
OBJECTIVE
To determine whether anterograde ejaculation is preserved after transurethral resection of both the prostate and bladder neck (TURP and TURBN).


METHODS
Between 1994 and 1997, 45 patients (mean age 53.2 years, range 42-62) with bladder neck obstruction and small obstructive adenomas (< 35 g) underwent TURP/TURBN, preserving part of the supramontanal prostate and prostatic urethra for > 1 cm from the verumontanum. They were assessed before and after 0.5-2 years to determine the type of ejaculation, symptom scores and sexual function, and compared with 10 similar patients who had undergone a conventional TURP.


RESULTS
With preservation of > 1 cm of the supramontanal prostate, anterograde ejaculation was maintained in 80% of the patients, whereas only one patient in the control group retained anterograde ejaculation.


CONCLUSIONS
The preservation of anterograde ejaculation after TURP (in approximately 20% of cases) and after transurethral incision of the prostate (> 90% cases) reported in the literature probably relates more to the presence of an adequate amount of residual prostatic tissue than to the existence of a hypothetical 'pre-prostatic sphincter'.
