Non-Antibiotic Prevention of Catheter Mechanic and Septic Complications in Patients with Long-Term Indwelling Catheters: a Crossover Prospective Study Involving L-Methionine.

Bacterial antimicrobial resistance (AMR) is a major public health concern in modern society caused by bacterial changes that impair the efficacy of infection-treating drugs. Non-antibiotic techniques are critical for controlling the antimicrobial resistance concern because they provide a means of alleviating symptoms without needing antibiotics. This prospective study aims to determine whether administering L-methionine reduces mechanical and bacterial problems associated with long-term indwelling urinary catheters. The trial focused on administering only L-methionine for a three-month period to patients who had long-term bladder catheters, either indwelling or suprapubic. The catheter exchange rates were categorized according to acute urinary tract infection, macroscopic haematuria and symptomatic urinary tract infection. During the time of inclusion, catheter-related incidents were recorded. The primary incident observed was acute urine retention caused by catheter obstruction in 63.6.
