Purpose: To present our initial experience with periurethral adjustable continence therapy (ACT™) for urinary incontinence due to intrinsic sphincter deficiency (ISD) in children. Methods: This is an approved prospective non-randomized pilot study (NCT03351634) aiming to treat children born with spinal dysraphism (SD) or exstrophy epispadias complex (EEC) with ACT™. Endpoints were patient-reported changes in daily pad count, 24-h Pad test and complications. Results: Since April 2018, 13 children (six girls, seven boys) were implanted at the median age of 12 years (5–16). The etiology of incontinence was neurogenic ISD (7/13, 54%) and EEC (6/13, 46%). After ACT™ implantation, continence (no pad or 1 security pad/day) was achieved in 9(69%) patients (5/7 SD, 4/6 EEC). Additionally, two (15%) patients had a significant improvement (decreasing Pad test from 1049 to 310 g at 3 months). One patient (7%) had no improvement. Results were stable at 21 months (6–43) of follow-up. Mean final balloon volume was 2.89 ml (± 0.85) with a median of 3 fillings to obtain continence. We had four revisions due to cutaneous port erosion (n = 3) and balloon migration (n = 1) and two definitive explantations. PinQ score was significantly improved (47 vs 40.5 with balloon, p = ns). Neither degradation of the upper urinary tract nor cystomanometric changes have been observed at 6 and 12 months postoperatively. Conclusion: Urinary incontinence due to ISD owing to EEC or SD can be successfully treated with ACT™ periurethral balloons. Given the minimal invasiveness of this therapy, it might be a first‐line option treatment in children with complex stress urinary incontinence. [ABSTRACT FROM AUTHOR]
