Objectives:
To assess the impact of endo-urethral stent (EUP) of incontinentation in spinal cord injured (SCI) men on ejaculation capacity.
First Criteria:
Presence of ejaculation after EUP.
Secondary Criteria:
Modification on ejaculation type, stimulation mode, possibility of sperm conservation in the same population.
Population And Methods:
A descriptive monocentric study including SCI subjects which underwent placement or change of temporary (Mémokath™ or Allium™) or definitive (Mémotherm™) EUP between January 2004 and January 2014 with at least one ejaculatory test. Are identified for each patient: the presence of ejaculation, type of ejaculation, stimulation mode used, number of frozen specimen and results from semen analysis.
Results:
Over 11 men with tetraplegia, complete for motricity, there were 8 (72%) for whom ejaculation was possible after laying EUP. Of these, 6 (55%) had an antegrade or antero-retrograde ejaculation. It was not possible to make a freezing straw in four of them due to infection of semen (2) or terato-oligo-astenospermia (1) or absence of reproductive project (1).
Conclusion:
In this small sample, it was found that over 70% ejaculation have been preserved after laying EUP and more than 50% with antegrade or antero-retrograde ejaculation. A larger study would identify how EUP may alter the ejaculatory capacity or quality of the ejaculate.
Level Of Evidence:
4.
