Comprehensive Complication Index in the Classification of Complications of Percutaneous Nephrolithotomy

Start date: May 1, 2022
Phase:
Study type: Observational [Patient Registry]

Postoperative complications should be reported systematically, objectively and reproducibly. The Clavien-Dindo Classification (CDC), first described in 2004, is the most popular classification system still in use today for assessing perioperative morbidity and mortality. In 2018, the European Association of Urology (EAU) validated this classification, which was originally defined for general surgery operations, for urological operations as well. There are aspects of the CDC that can be critical and weak. The CDC's main weakness is that in the vast majority of studies it only considers the most serious complications. Minor complications are often overlooked and the overall complication burden is therefore underestimated. Because of this vulnerability, it is difficult to compare complications from different patients. For example, it cannot be determined whether a patient with two Grade I complications has higher postoperative morbidity than a patient with one Grade II complication. To address these limitations, the Comprehensive Complications Index (CCI) was defined in 2013 as a new and more comprehensive scoring system for surgical complications. The CCI is essentially an index based on the CDC, but sums all postoperative complications by severity and scores them on an interval scale. It is scored from 0 (no complications) to 100 (patient's death) for each patient. CCI in Urology Practice; Validated for Radical Cystectomy, Radical Prostatectomy, Radical Nephroureterectomy, Partial Nephrectomy. In recent years, validation studies of this index have been carried out in endourological surgeries.
