[The partial recovery of kidney function in chronic uremia patients during hemodialysis treatment]

Out of 432 patients placed on the treatment with hemodialysis (HD) for terminal renal failure (TRF) at the All-Union Nephrologic Center from January 1, 1978 to December 31, 1987, 17 patients manifested partial recovery of renal function, which enabled dialysis treatment to be discontinued for a time. Among the 17 patients with noticeable improvement of renal function, 8 presented with lupoid rapid-progressing glomerulonephritis (RPGN), 2 with RPGN associated with hemorrhagic vasculitis, 1 with idiopathic RPGN, 4 with chronic glomerulonephritis (CGN), 1 with chronic pyelonephritis, and 1 with polycystic kidneys. In 11 patients with RPGN, the rate of renal failure progression, expressed by the regression coefficient, was much higher among those in whom HD treatment was discontinued that in the group of patients without renal function recovery. In the 4 patients with CGN, renal function was recovered after the correction of marked disorders of purine metabolism, whereas in the 1 patient with chronic pyelonephritis and in the 1 with polycystic kidneys after urinary infection elimination. According to the ultrasonography data, out of the 17 patients with partial recovery of renal function, the size of the kidneys turned out normal in 14 patients.
