Implant of ATOMS® system for the treatment of postoperative male stress urinary incontinence: an Italian multicentric study.

BACKGROUND

The aim of this study was to evaluate efficacy and safety of the ATOMS system for the treatment of postoperative stress urinary incontinence (SUI).

METHODS

We included all consecutive male patients referring for postoperative SUI and treated with ATOMS system from June 2013 to July 2017. Patients received anamnesis, 24 h Pad Test, Pad count, physical examination, urodynamic evaluation, ICIQ-UI SF questionnaire. We excluded patients with low bladder capacity and compliance, uncontrolled detrusor overactivity.

RESULTS

We treated 98 patients with median age of 70.21±10.02 years. The most common cause of SUI was open radical prostatectomy in 79 patients. Ten patients had undergone urethrotomy, 7 bladder neck incision, 14 adjuvant radiotherapy. Thirty-nine patients suffered of mild incontinence (24 h Pad Test <200 g), 49 moderate incontinence (200-400 g), 10 severe incontinence (≥400 g). Thirty-one patients underwent previous incontinence surgery: 29 ProACT, 3 artificial urinary sphincters (in 2 cases both devices), 1 bulking agents and subsequent male sling. Median follow-up was 21.5 months. We had a significant reduction of mean 24 h Pads Test, pad count and ICIQ-UI SF questionnaire (P<0.01). At last follow-up 47.96% of patients were dry and 79.59% reached social continence. A high incontinence grade, adjuvant radiotherapy, previous urethral surgery and incontinence surgery have been associated with lower continence results. We had complications in 33 patients (33.7%). The device was removed in 4 cases due to scrotal port erosion and in one case due to persistent pain.

CONCLUSIONS

The ATOMS system seems to be an effective and safe surgical treatment for postoperative male SUI.
