title: Sodium-losing nephropathy.
abstract: We studied prospectively 18 patients with sodium-losing nephropathy. In 12 patients (66.7 per cent) the sodium-losing nephropathy was owing to obstructions, challenging the hitherto existing concept that the most common cause of the condition is pyelonephritis. The diagnosis of sodium-losing nephropathy is important in urological practice since sodium repletion in these cases shortens significantly the hospitalization and preoperative waiting time.
