Self-report of difficult defecation is associated with overactive bladder symptoms

Abstract

Aims: The association of dysfunctional bowel elimination with lower urinary tract symptoms is well known in children, but not in adults. It was our objective to assess lower urinary tract symptoms (LUTS) in women who report difficult defecation (DD).

Methods: This is a secondary analysis of 2,812 women, aged 35-64, who participated in a telephone interview. All subjects were asked "When you move your bowels, does the stool come out easily?" DD was considered present in those answering "no." All subjects were queried regarding LUTS, urinary infections in the past year, self-perceived health status, medical history, and demographics. Symptoms of stress incontinence (five items), urge incontinence (five items), and the impact of these symptoms on their quality of life were solicited from subjects reporting more than 12 episodes of incontinence in 1 year.

Results: DD was reported by 10.4% (290/2,790) of women. Women with DD had higher LUTS than those who did not: nocturia (mean 1.8 ± 0.1 vs. 1.3 ± 0.0), urgency (47.6% vs. 29.2%), increased daytime frequency (mean 8.2 ± 0.3 vs. 7.2 ± 0.1), dysuria (22.9% vs. 13.7%), and a sensation of incomplete bladder emptying (55.6% vs. 28.2%). DD women were more often menopausal, reported a fair or poor self-reported health status, and had a higher number of comorbidities, less formal education, and lower annual household income.

Conclusions: Women with symptoms of DD have an increased rate of LUTS, consistent with the diagnosis of overactive bladder without incontinence. The pathophysiology underlying this association is worthy of future research.
