The patient denied any history of diabetes and hypertension. On evaluation with X-ray Kidney-Ureter-Bladder and ultrasound (USG) of abdomen, he was found to have left upper ureteric calculus (size: 13 mm) with left mild hydronephrosis and normal right kidney. He subsequently underwent uneventful extracorporeal shockwave lithotripsy (ESWL) with Dornier compact alpha electromagnetic lithotripter for the calculus. Three thousand shockwaves were delivered to the stone. The procedure was uneventful and the patient was discharged. Twenty-four hours later, the patient presented with severe left flank pain. On clinical examination, he had tachycardia (pulse rate: 100/min), normal blood pressure (138/76 mm Hg) and tenderness in the left flank region. Laboratory examination revealed the following parameters:Haemoglobin: 10.2 g/dL. … ER -
