The prevalence of overt, occult, and no-demonstrated stress urinary incontinence and their clinical and urodynamic findings in women with advanced-stage cystoceles.

ABSTRACT

OBJECTIVES: To elucidate the prevalence of overt, occult and no demonstrated (ND) stress urinary incontinence (SUI) in women with advanced-stage cystoceles. STUDY DESIGN: Between November 2011 and January 2017, all women with ≥stage 2 cystoceles were retrospectively enrolled. Overt SUI was diagnosed before the prolapse reduction test, and occult SUI was diagnosed when urine leakage was noted after a reduction test with vaginal gauze. Otherwise, a diagnosis of ND-SUI was made. MAIN OUTCOME MEASURES: The prevalence, clinical and urodynamic findings of overt SUI, occult SUI, and ND-SUI. RESULTS: In 480 enrolled women, 62% had overt SUI, 17% had occult SUI, and 21% had ND-SUI. The occult SUI group had the most advanced prolapse. The pad weight results after prolapse reduction (37.3 ± 44.3 vs. 13.4 ± 21.9, p < 0.05), the bladder capacity (243 ± 54 vs. 273 ± 48, p < 0.001), and questionnaires regarding life quality were significantly different between the overt SUI and the occult SUI groups. Bladder oversensitivity (BO) was the most common urodynamic diagnosis (389/480, 81%), especially in overt SUI, while urodynamic stress incontinence (56/480, 12%) and detrusor overactivity (60/480, 13%) were uncommon. The cutoff value of stage 3 uterine prolapse was the strongest predictor for predicting occult SUI (sensitivity = 30.3%, specificity = 78.5%; area = 0.60, 95% CI 0.52-0.68). CONCLUSIONS: SUI occurs in a ratio of 311 among cases with overt, occult, and no demonstrable symptoms. BO is the most common urodynamic diagnosis. Pad test with prolapse reduction remains an important tool, especially for coexistent stage 3 uterine prolapse.
