Cough-Induced Detrusor Overactivity—Outcome after Conservative and Surgical Treatment

<b>Background/Objectives</b>: The most common variant of mixed urinary incontinence is stress-induced urge urinary incontinence with the correlating urodynamic findings of cough-induced detrusor overactivity (CIDO). This prospective study assessed the clinical outcomes and leakage improvement among patients with CIDO following conservative or surgical treatment. <b>Methods</b>: We included patients with CIDO treated at our tertiary referral center from January 2018 to July 2021 in this prospective cohort study. The detection of a detrusor contraction after a cough was diagnosed as CIDO by urodynamic multichannel testing. All the patients in our study received personalized care, with behavioral therapy and anticholinergic/betamimetic treatment as a first step. If leakage persisted, patients were given a choice between pelvic floor muscle exercises (PFMEs), periurethral bulking or a midurethral sling. The primary outcome was the mean difference in urine leakage in the pad test before and six months after treatment. <b>Results</b>: Thirty-five patients met the inclusion criteria for CIDO and all presented a positive pad test at baseline (mean: 27 g). All 35 patients participated in behavioral therapy and anticholinergic/betamimetic treatment. Twenty-two patients (62.9%) underwent PFME, twelve patients (34.2%) received periurethral bulking, and nine patients (25.7%) received a midurethral sling. After all the treatments, our cohort showed a significant improvement in the pad test (mean: 5.7 g, <i>p</i> < 0.001). The result was more favorable after periurethral bulking than the midurethral sling (<i>p</i> < 0.001). <b>Conclusions</b>: This study shows the effectiveness of conservative treatment as a first step. In cases needing further treatment, bulking agents may be superior to PFME and midurethral propylene slings, offering new perspectives in the field of urogynecology and urinary incontinence.
