Background: The complications of ureterosigmoidostomy include hyperchloremic acidosis, pyelonephritis, development of colonic malignancy and rarely hypokalemia.
Case Report: A twenty-four years old man was admitted to the hospital with tetraparesis. He had undergone bilateral ureterosigmoidostomy ten years ago after a car accident which caused bladder rupture. Laboratory investigations revealed severe hypokalaemia 1.8 mmol/l (normal range 3.5-5.5 mmol/l). The patient was treated with intravenous potassium chloride and also received oral potassium chloride and acetozalamide. Patient’s clinical condition dramatically improved within 72 hours concomitant with the correction of serum potassium. We present a patient with secondary quadriparesis due to severe hypokalemia caused by ureterosigmoidostomy.
Conclusions: Hypokalemia should be considered in differential diagnosis of patients with any degree of paresis in patients with a history of ureterosigmoidostomy.
