Abstract
Introduction and hypothesis
Stress urinary incontinence (SUI) is in part attributed to qualitative and quantitative changes in connective tissue of the urogenital tract. We examined the association of collagen type I a1 (COLIA 1) Sp1 polymorphism with the risk of SUI.
Methods
Forty-five postmenopausal women suffering from urodynamically verified SUI (study group) were compared to 45 healthy volunteers (control). DNA was extracted from peripheral blood. The genotyping concerning the type 1 a1 collagen gene Sp1 polymorphism was performed with polymerase chain reaction.
Results
The polymorphic T allele was overrepresented in the SUI patients (63.2% versus 36.8%, p = 0.016). Odds ratio for SUI in women harboring the T allele was 2.19 (95% CI 1.149–4.176) compared to women with the wild-type genotype.
Conclusions
The COLIA1 Sp1 polymorphism is associated with increased prevalence of stress urinary incontinence in postmenopausal women.
