Abstract

Introduction

Local renin–angiotensin systems exist within the genitourinary tract, specifically in the bladder and urethra. Experimental data suggest that angiotensin receptor blockade with either angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) decreases both detrusor overactivity and urethral sphincter tone leading to decreased urge incontinence (UUI) and increased stress urinary incontinence (SUI). This has not been examined in a human population.

Methods

Data from the National Health and Nutrition Examination Survey (NHANES) was accessed for the years 2001–2008. Multivariate logistic regression was used for modeling.

Results

We studied 8,754 females and 8,886 males who met inclusion criteria. Use of ACE inhibitors or ARBs was not associated with a change in SUI in either men or women. In men, use of an ACE inhibitor or ARB was associated with a statistically significant 25–30% decrease in UUI (monthly or any urge incontinence). A similar, albeit non-significant trend was also seen for daily and weekly UUI. Other antihypertensive medications (diuretics, beta-blockers, calcium-channel blockers) were not associated with a decrease in UUI. In subanalysis, duration of ACE inhibitor or ARB use did not alter the strength of the effect on UUI nor did an elevated prostate specific antigen (PSA) level (used as a surrogate for bladder outlet obstruction due to benign prostatic hypertrophy). ACE inhibitor and ARB use did not affect UUI rates in women, though did show a trend for improvement in nulliparous women without SUI.

Conclusion

Angiotensin receptor blockade may be a viable treatment approach for the treatment of UUI, especially in men. Neurourol. Urodynam. 33:1178–1181, 2014. © 2013 Wiley Periodicals, Inc.
