Objectives. To compare how urinary symptoms affect the quality of life in g
roups of men with postprostatectomy incontinence treated with collagen vers
us artificial urinary sphincter implantation.
Methods. Two cohorts of men, one which received urethral collagen injection
and one artificial urinary sphincter (AUS) implantation, were surveyed wit
h a validated quality-of-life questionnaire to assess how their urinary dys
function impacted their daily activities. The mean impact score and bother
score for the two groups were compared. In addition, the overall degree of
continence between the groups was assessed.
Results. At a mean follow-up of 19 months, 8 (20%) of 41 patients treated w
ith collagen injections were at least socially continent, requiring one pad
daily or less. In comparison, 27 (75%) of 36 men treated with an AUS were
at least socially continent (P <0.001). Both the impact score and the bothe
r score from the quality-of-life questionnaire were significantly lower in
the group treated with the AUS than in the group treated with collagen.
Conclusions. Patients receiving an AUS achieved significantly higher contin
ence rates. Also, the quality of life of men treated with an AUS was improv
ed compared with that of the men treated with collagen injection. UROLOGY 5
