Antibiotic Prophylaxis in Transurethral Prostate Resection (TURP) and Transurethral Bladder Tumour Resection (TURB)

Main objective: To investigate the safety of omitting antibiotic prophylaxis in TURP (transurethral resection of the prostate) and TURB (transurethral bladder tumour resection) in patients without a pre-operative catheter or \> 100 WBC in the pre-operative urinary sample (TURP) or clinical signs of urinary infection (TURB). Secondary objective: To investigate post-operative bacteriuria after TURB and TURP in our population. Principal inclusion criterium: Patients undergoing TURP or TURB. Primary exclusion criterium: TURP: pre-operative catheter or \> 100 white blood cells in the pre- operative urinary sample. TURB: pre-operative catheter or clinical signs of infection (fever, nyctalgia). Primary endpoint: Post-operative infection. Secondary endpoint: Post-operative bacteriuria.
