Critical analysis of complications after robotic‐assisted radical cystectomy with identification of preoperative and operative risk factors

Study Type – Therapy (case series) Level of Evidence 4 OBJECTIVE To better characterize short‐ and long‐term complications in patients after robotic‐assisted radical cystectomy (RRC) using standardized complications‐reporting systems, and to identify preoperative and operative risk factors predicting their occurrence. PATIENTS AND METHODS Data were collected for 79 consecutive patients with bladder cancer undergoing RRC with extracorporeal urinary diversion by one surgeon at our institution. Complications occurring ≤90 days after RRC were graded according to two standardized reporting methods (Memorial Sloan Kettering Cancer Center and Modified Clavien), and additionally stratified by organ system. Nineteen preoperative and operative variables were tested by univariate analysis for association with the occurrence of one or more postoperative complications. Variables with a significant (P 5000 mL, with respective ORs of 12.7, 9.7 and 42.1. CONCLUSION Even among relatively sick patients with frequent advanced disease, the vast majority of complications after RRC are low grade. High‐grade complications are infrequent and similar in nature to high‐grade events after open RC, and a notable proportion may occur at >30 days after RRC unders
