Objective: Men of any age with bladder outlet obstruction and without measurable enlargement of the prostate constitute ideal candidates for TUIP. Effectiveness of any technique with respect to flow rate improvement is firmly established, indifferently whether unilateral or bilateral. But there is a wide variation in the reported incidence of retrograde ejaculation with unilateral and bilateral incision.
Material and methods: The retrospective analysis of our 45/57 available patients treated with this technique, between January 1993 and March 1995, does not show a major incidence of this complication for the bilateral incision, with an overall incidence of 6.6% (3/45 patients).
Conclusions: Although ejaculation may be preserved, it cannot be guaranteed.
