Female urinary stress incontinence in terms of connective tissue biochemistry.
The role of connective tissue in the aetiology of female stress incontinence has been investigated. Collagen content and extractability as well as estrogen receptor concentration in vesico-vaginal fascia were measured after small tissue biopsies had been obtained during vaginal repair surgery in cases of urinary incontinence. The mean concentration of estrogen receptor in vesico-vaginal fascia among incontinent women was 49.4 +/- 14.8 fmol/mg of protein as compared to 29.6 +/- 13.1 in continent control group (P < 0.03; t-test). The mean hydroxyproline concentration in vesico-vaginal fascia of incontinent women was 13.8 +/- 2.6 micrograms/mg wet weight, whereas in the control group it was significantly higher 20.6 +/- 2.4 (P < 0.001). The role of connective tissue components in the aetiology of female stress incontinence is discussed.
