RESUMO
BACKGROUND: Radical cystectomy (RC) has a high morbidity and leads to a significant socio-economic burden. We aimed to investigate pre-, intra-, and post-operative variables to create a novel score predicting both post-operative clinical (complications) and economic (length of hospital stay) outcome after RC. METHODS: We retrospectively evaluated clinical and histopathological data of 317 patients after RC. We performed univariate and multivariate logistic regression analyses to identify variables associated with post-operative clinical (30-day morbidity according to Clavien-Dindo complications) and economic (length of hospital stay) outcome. RESULTS: In multivariate analysis, a high number of intraoperative transfusions (T) of packed red blood cells predicted major complications (odds ratio [OR] 1.68, 95% confidence interval [CI] 1.10-2.58, p = 0.017), preoperative potassium (P) level predicted three or more complications (OR for high preoperative potassium 0.71, 95% CI 0.52-0.98, p = 0.037), and high drain (D) loss on post-operative day 1 predicted a longer hospital stay ≥ 22 days (OR 1.57, 95% CI 1.04-2.35, p = 0.003). The PT2D-Score was able to predict three or more complications (area under the curve: 0.70, 95% CI 0.61-0.78, p < 0.001) and a hospital stay of ≥ 22 days in patients after radical cystectomy (area under the curve: 0.63, 95% confidence interval 0.53-0.72, p = 0.012). CONCLUSIONS: The novel PT2D-Score combines preoperative potassium level, intraoperative blood transfusion, and post-operative drain loss to predict both clinical (30-day morbidity) and economic (length of hospital stay) outcome for patients undergoing RC. After validation in a larger cohort, the novel PT2D-Score might serve as an additional criterion to identify patients for intensified monitoring after RC.
