succimer and Polyuria

A 43-year-old female patient with hypertension was diagnosed as having one-kidney renovascular hypertension with dysfunction of the contralateral kidney, and percutaneous transluminal renal angioplasty was carried out. Marked polyuria was observed during the 2- to 72-hour postoperative period. During the 12- to 18-hour period of polyuria, the urine volume was 8.9 liters/6 h, which was 62% of the glomerular filtration, and was accompanied by high fractional excretion of sodium and of potassium and a high urine beta 2-microglobulin level. The mechanism of polyuria in this case is discussed.
