Brief summary

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.

Detailed description

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

Interventions

DRUGoral applications of TMP/SMX 800/160 mg (Nopil forte® tablets)

five oral applications of TMP/SMX 800/160 mg (Nopil forte® tablets) at the evening of the surgery and thereafter twice daily on day 1 and 2 after surgery while the patient is in hospital.

DRUGoral applications of Placebo

five oral applications of Placebo at the evening of the surgery and thereafter twice daily on day 1 and 2 after surgery while the patient is in hospital.

Inclusion criteria

* Obstructive voiding disorder (e.g. benign prostate hyperplasia, obstructive prostate cancer) * Planned Transurethral resection of the prostate (TURP) or Greenlight Laser (GL)

Exclusion criteria

* Evidence for (catheter associated-) UTI, with or without antibiotic treatment in the last 7 days prior to randomisation. * Any evidence of a history of positive urine culture (cfu ³105/ml in midstream-urine with no more than two species) and resistance to TMP/SMX in the last 7 days prior to randomisation. * Known contraindication against study drugs according to the Swissmedic package leaflet (e.g. known liver dysfunction, renal insufficiency; patients with glomerular filtration rate (calculated by the Modification of Diet in Renal Disease (MDRD) or Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) \<30ml/min or dialysis patients will be excluded). * Antibiotic treatment for any reason within 7 days prior to randomisation * Indication for Antibiotic prophylaxis (AP) for other reasons (e.g. endocarditis prophylaxis, transplanted patients under systemic immunosuppression).
