We examine the case of a 44yearold man with invasive bladder cancer who underwent an open radical cystectomy. After extubation, the patient is transferred from the operating room to the Intermediate Care Unit, where he complains of severe lumbar pain on a visual analog scale of 10 that is unresponsive to opioids and is diagnosed with rhabdomyolysis due to compartment syndrome. Multidisciplinary care and multimodal analgesia approaches were used; no fasciotomy was performed; and a favourable outcome was achieved. https://aacc.tums.ac.ir/index.php/aacc/article/view/634
