Free Water Clearance: A Clinical marker of Patients with Obstructive Uropathy / 대한비뇨기과학회지

ABSTRACT

Renal functional changes following relief of obstruction were investigated with a prospective aspect in a series of 15 postoperative patients using standard renal function measurements with emphasis on osmolar and free water clearance. Sequential measurements of free water clearance revealed earlier changes of postoperative renal function than that of standard renal function. The advantage of this measurement was in postoperative patients with adequate amount of urine output or diuresis. It may be helpful to the management of patients with obstructive uropathy and to early prediction of acute renal failure, especially in patients with post-obstructive diuresis.
