Coital urinary incontinence in an Australian population.

A total of 1,012 patients referred to 4 urodynamic centres were questioned, and subsequently investigated. Coital incontinence was present in 192 of the 839 (23%), who were sexually active. Ninety-five patients (49%) had the urodynamic diagnosis of genuine stress incontinence, alone or in association with cystocoele or interstitial cystitis. Fifty-one (26.6%) had urodynamically proven detrusor instability with or without interstitial cystitis. Forty-five (23.4%) had dual pathology as the final urodynamic diagnosis.
