The optimal duration of antimicrobial prophylaxis (study medication Cotrimoxazole (Trimethoprim/Sulfamethoxazole)) in transurethral resection of the prostate and Greenlight Laser vaporisation of the prostate is investigated by comparing a guideline-conform single-dose prophylaxis (intervention) versus usual clinical care (i.e. 3-day prophylaxis; control) for prevention of urinary tract infections.
Increasing antimicrobial resistance rates have a substantial impact on morbidity, mortality and healthcare costs and is particularly prevalent among urological patients due to an overuse of antimicrobial agents for therapeutical and prophylactic indications. Transurethral resection of the prostate is one of the most frequently performed urological procedures in Switzerland and a single-dose of antimicrobial prophylaxis is recommended to reduce postoperative urinary tract infections. For photoselective vaporisation of the prostate with the Greenlight Laser, a similar operative alternative, there are currently no international guidelines for antimicrobial prophylaxis.
The optimal duration of antimicrobial prophylaxis in transurethral resection of the prostate and Greenlight Laser vaporisation of the prostate is investigated by comparing a guideline-conform single-dose prophylaxis (intervention) versus usual clinical care (i.e. 3-day prophylaxis; control) for prevention of urinary tract infections.
The study medication Cotrimoxazole (Trimethoprim/Sulfamethoxazole) is a routinely used antimicrobial substance recommended in international and in-house guidelines for antimicrobial prophylaxis and treatment of urinary tract infections. Perioperative antimicrobial prophylaxis will be Cotrimoxazole short infusion in both groups. Postoperative study medication packages consists of either five tablets of placebo or five tablets of Cotrimoxazole (Nopil forte®) 800/160mg using licensed product repacked in a new immediate container which is blinded
