A 70 year old man with known prostatic malignancy and stage III chronic kidney disease developed fevers, left flank pain, urinary frequency and confusion. He deteriorated rapidly in ED becoming hypotensive and drowsy. He had a lactic acidosis. CT abdomen was showed left hydronephrosis and hydroureter and was suggestive of an infected obstructed kidney. During the scan he became peri-arrest and was intubated. There was a logistical delay in achieving nephrostomy, and he was requiring escalating levels of noradrenaline. Vasopressin was commenced in order to maintain his mean arterial pressure and reduce the noradrenaline requirement from 0.8mcg/kg/min. Nephrostomy was achieved around 12 hours later and he subsequently made a full recovery.
