Outcomes with the Adjustable Transobturator Male System (ATOMS) for the Treatment of Male Stress Urinary Incontinence After Prostate Surgery and the Impact of Previous Radiotherapy
Abstract
Background and objective: The adjustable transobturator male system (ATOMS) is an established treatment for patients with urinary incontinence after prostate surgery. Our objective was to evaluate the efficacy and the complication burdens associated with ATOMS with a focus on exploring the potential impact on previous radiotherapy (RT). Methods: We performed a retrospective analysis for consecutive patients who underwent ATOMS implantation procedure at a tertiary center over an 11-yr study period. Outcomes of interest were dryness at 3-mo follow up, postoperative complications (≤30 d), and late treatment failures (>30 d). Key findings and limitations: A total of 118 patients underwent ATOMS surgery performed by five different surgeons. Median follow-up was 67 mo (interquartile range 41–95). The mean 24-h pad count after surgery was 1.1 (range 0–8) and the mean reduction in pad weight was 179 g (range 0–1080). There was no significant difference in the reduction in pad use between groups with and without RT (−1.7 vs −2.4; p = 0.13). Multivariable analysis revealed that RT, degree of incontinence, and age were not risk factors for reoperation. Conclusions and clinical implications: ATOMS implantation is feasible in patients who have undergone prostate RT and patients with severe stress urinary incontinence after prostate surgery. We found that RT was not a risk factor for reoperation and there was no significant difference in pad weight reduction by RT status. This study offers new insight into potential incontinence surgery for male patients with stress urinary incontinence and previous RT. Patient summary: We assessed outcomes for patients who had an ATOMS (adjustable transobturator male system) device implanted to control stress urinary incontinence after prostate surgery. After implantation, 52.5% of the patients reported zero leakage and 39.9% reported only mild incontinence. Our results show that this device can improve continence after prostate surgery and is also suitable in patients who underwent radiotherapy.
