Sacral neuromodulation therapy for urinary and defecatory disorders: experience in a Latin American public hospital

Objective: To To show the experience of a Latin American public hospital, with SNM in the management of either OAB, NOUR or FI, reporting feasibility, short to medium-term success rates, and complications. Methods: A retrospective cohort was conducted using data collected prospectively from patients with urogynecological conditions and referred from colorectal surgery and urology services between 2015 and 2022. Results: Advanced or basic trial phases were performed on 35 patients, 33 [94%] of which were successful and opted to move on Implantable Pulse Generator [GG] implantation. The average follow-up time after definitive implantation was 82 months (SD 59]. Of the 33 patients undergoing, 27 (81%]reported an improvement of 50% or more in their symptoms at last follow-up. Moreover, 30 patients (90%] with a definitive implant reported subjective improvement, with an average PGI-I "much better" and 9 of them reporting to be "excellent" on PGI-I. Conclusion: SNM is a feasible and effective treatment for pelvic floor dysfunction. Its implementation requires highly trained groups and innovative leadership. At a nation-wide level, greater diffusion of this therapy among professionals is needed to achieve timely referral of patients who require it.
