About this study

Cystectomy with urinary diversion (ileal conduit, orthotopic ileal bladder substitute, continent catheterizable pouch) is the best treatment option for patients with muscle-invasive bladder cancer. This intervention is one of the most challenging in urology and has a high rate of postoperative complications including around 30% of postoperative infections.

Perioperative antibiotic prophylaxis (PAP) is widely accepted as a crucial preventive measure to reduce the incidence of surgical site infections (SSI). The rationale for PAP is the reduction of the local bacterial load at the site and time of intervention, and therefore a short duration of PAP of 24 to maximal 48 hours is recommended for all clean to clean-contaminated procedures..

Evidence supporting the optimal duration of PAP for radical cystectomy with urinary diversion is lacking. Based on data extrapolated from abdominal surgery, current guidelines recommend short-term PAP (≤24h) for all clean-contaminated procedures including radical cystectomy.

However, a recent evaluation revealed a significant inter-hospital variability of PAP and showed that extended use (>48h) was common in patients undergoing radical cystectomy. Importantly, this study also demonstrated that longer duration of PAP incurred higher costs and was associated with an increased rate of C. difficile colitis. A small, prospective, non-randomized study showed equal efficacy of short-term PAP in preventing postoperative infections in patients undergoing radical cystectomy with ileum conduit compared to extended PAP. Nonetheless, larger randomized clinical trials supporting these findings are lacking.

The unwarranted extended use of antibiotics is a major concern as exposure to antibiotics is a driving force for the development of (multi-) resistant bacteria and will lead to an increasing number of difficult-to-treat infections. This has been recognized on both national and international levels and is addressed within antimicrobial stewardship frameworks.

This study will compare current practice (>48h PAP, "extended PAP") with the guideline recommended approach (24h PAP, "short term PAP") in a single-centre, prospective, randomised clinical non-inferiority trial. The primary outcome is the rate of SSI within 90 days post surgery. The aim of the study is to generate currently lacking evidence allowing for an optimised PAP strategy in a challenging surgical setting.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate of Surgical Site infections (SSI)

    Rate of surgical site infections occurring within 90 days post surgery will be calculated for each patient.

    Measured: 90 days

  2. Time to event of SSI

    Time to event of SSI (event free survival analysis)

    Measured: 90 days

  3. Rate of Urinary tract infections (UTI)

    Rate of urinary tract infections occurring within 90 days post surgery will be calculated for each patient.

    Measured: 90 days

  4. Time to event of UTI

    Time to event of UTI (event free survival analysis)

    Measured: 90 days

Secondary outcomes (4)
  1. Rate and type of Antibiotic associated adverse events (AEs)

    Rates and types of antibiotic associated AEs occurring within 30 days post surgery (direct AEs such as hypersensitivity reaction, hepatotoxicity, renal toxicity etc and indirect AEs such as line associated infections, C.difficile diarrhoea) will be assessed for each patient.

    Measured: 30 days

  2. Frequency of multi-drug-resistant bacteria in urinary samples

    The frequency of multi-drug-resistant bacteria in urine samples obtained at predefined time points during the first 30 days post surgery will be calculated for each patient

    Measured: 30 days

  3. Changes in fecal flora

    Changes in the composition of the fecal flora will be assessed in fecal samples collected at pre-specified time points

    Measured: 30 days

  4. Antibiotic associated costs

    Directly antibiotic associated costs incurred during 30days post surgery will be assessed

    Measured: 30 days
