Adjustable Transobturator Male System (R) (ATOMS) as a novel treatment for men with stress urinary incontinence in the United Kingdom

Objectives: To investigate the first experience in the United Kingdom of using the Adjustable Transobturator Male System (R) (ATOMS) in treating men with stress urinary incontinence (SUI). Methods: Between 2015 and 2021, 71 men (average age: 70.3, range: 50-81 years) were recruited and followed up. Of these, 67 (94%) had SUI secondary to a radical prostatectomy and 16 (23%) had previous radiotherapy post-prostatectomy. Seventy men underwent an insertion of ATOMS (R) under general anaesthetic. In one patient, due to his underlying morbid obesity, it was not possible to insert ATOMS and thus he was excluded from the study. Follow-up was up to 6 years (mean: 4 years, range: 2-6 years). Results: Out of 70 men, 53 (76%) were dry after ATOMS insertion (defined as using a maximum of one pad per day for reassurance only). Dryness was achieved within 6 months for 34/53 patients (range: 1-24 months). The average pad use was 3.4 pre-operatively and 0.7 post-operatively. Of the men who did not achieve dryness, 7/17 (41%) had previously undergone radiotherapy. There were 11 (16%) complications: two cases of infected device requiring removal, one case of balloon mechanism erosion requiring re-implantation, one case of balloon mechanism require repositioning, four cases of persistent perineal or scrotal pain, two cases of urinary retention and one case of a superficial wound infection treated medically. Overall, five devices were removed. Conclusions: The ATOMS appears to be a safe and efficacious treatment for men with SUI. Previous radiotherapy decreased the efficacy of ATOMS. Further studies on ATOMS with larger numbers of patients and longer follow-ups are required. In particular, establishing randomised control trials to confirm these positive outcomes as well as ascertain its long-term safety profile.
