S. Hidar et al., Periurethral injection of silicone microimplants in the treatment of urinary incontinence due to sphincter deficiency., PROG UROL, 10(2), 2000, pp. 219-223
Objective : To assess the mid-term efficacy of periurethral injection of si
licone microimplants in women with urinary incontinence due to intrinsic sp
hincter deficiency
Material and Methods : Between July 1992 and March 1999, 25 women ( mean ag
e 65.17 +/- 13.5 years) with intrinsic sphincter deficiency underwent periu
rethral injection of silicone microimplants.
Urodynamic investigations were performed prior to and after surgery
The subjective degree of continence was also assessed for 3 years.
Results : Subjective success rate were 80%, 72%, 65%, 60%, and 60% at 6 wee
ks, 3 months, 6months, 1 year and 3 years, respectively.
Post-operative maximum urethral closure pressure was significantly increase
d (post-op 32.35 +/- 18.04 cm H2O versus pre-op 23.68 +/- 9.4 cm H2O; P < 0
.01)
No serious operative or postoperative complication occured.
Conclusion. In spite of time-dependent decrease in success rate periurethra
l silicone microimplants injection remains an effective and safe procedure
for women with urinary incontinence due to intrinsic sphincter deficiency.
