Predisposing factors for rhabdomyolysis in patients undergoing urethroplasty

Background: This study aims to evaluate the relationship between creatine kinase (CK) values, the incidence of rhabdomyolysis and the association with surgical time and body mass index (BMI) of patients undergoing urethroplasty in this position. Materials and Methods: Retrospective study, patients undergoing urethroplasty and lithotomy as their surgical positioning, in a public hospital from São Paulo from 2022 and 2023. Data collection was performed manually in the electronic medical records by trained researchers, using a standardized form. The significance level considered was P < 0.05. Results: Total of 58 patients, average age was 67.02 years, the postoperative CK variable was categorized into values ≤500 with 39 patients (67%) and >500 with 19 (32.8%). The BMI variable was also categorized into <25 with 18 (31%) of patients, 25–29.9 with 21 (36.2%) of patients, and >30 with a total of 19 (32.8%). The average duration of the surgical procedure was 271.45 min. Conclusion: It is important to guide the preoperative preparation of the patient with weight loss and reduce the surgical time in addition to improving the expertise of the team and the possibility of two simultaneous teams for graft removal to avoid complications.
