The Uro-Clavien–Dindo system—Will the limitations of the Clavien–Dindo system for grading complications of urological surgery allow modification of the classification to encourage national adoption within the UK?

SummaryAlthough quality outcome assessment is gaining widespread recognition, there is still no consensus about grading postoperative complications in urology. There have been several attempts to grade surgical complications. The Clavien–Dindo system has been standardised and validated. However there are limitations when using the system to grade urological complications. We suggest modification of the Clavien–Dindo system to include intraoperative complications. Widespread implementation of the grading system could benefit the transparent reporting of complications to demonstrate quality outcomes.
