Rhabdomyolysis After Total Abdominal Hysterectomy Requiring Urgent Hemodialysis Due to Hyperkalemia

A 63-year-old woman with a past medical history of invasive ductal carcinoma of the breast, status post lumpectomy and chemoradiation, 15 cm left inguinal-femoral enlarged lymph node consistent with high-grade serous carcinoma of the ovary and 4.7 cm right adnexal mass underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and lymph node dissection with cystoscopy and bilateral ureteral catheter placement. There was no intraoperative complication. After surgery, patient's urine output decreased, and she developed acute kidney injury (AKI). Initially, it was thought that her reduced output might be due to surgery/anesthesia. She also developed arm and leg weakness raising suspicion for stroke. The neurological workup was unremarkable for any acute abnormality. Her creatinine kinase (CK) level was >20,000 u/l consistent with rhabdomyolysis. She was hydrated aggressively and required hemodialysis due to hyperkalemia. During the hospital course, her kidney function improved, and rhabdomyolysis resolved, and she did not require dialysis after discharge.
