Minimally invasive treatment of urinary incontinence has become a subj
ect of major interest in recent years. We examined the use of transure
thral collagen injection for incontinence treatment. a total of 48 pat
ients were selectet for this procedure from April 1993 to February 199
7 - 26 male patients (19 post-RPX incontinence and 7 post-TUR incontin
ence) and 22 female patients (all after previous incontinence surgery)
were treated by injection of collagen into the continence region. The
whole group underwent an average of 1.8 sessions, and a mean collagen
injection volume of 14.5 ml was delivered per session. Mean follow-up
was 9.2 months. Of the female population, 68.2% were cured or greatly
improved. In the male population only 47.3% of the post-RPX patients
and 6/7 of the post-TUR patients benefited from the procedure. In male
s, treatment outcome depends on the degree of pretreatment incontinenc
e, because all grade III incontinence patients did worse. Therefore we
conclude: transurethral collagen injection is an interesting method i
n the treatment of urinary incontinence if proper patient selection is
assured.
