[IMPACT OF THE UPPER URINARY WAYS DRAINAGE METHOD ON RESTORATION OF RENAL FUNCTION IN PATIENTS, SUFFERING ACUTE OBSTRUCTIVE PYELONEPHRITIS].

Renal function was studied, using radionuclide renography, in 142 patients, suffering acute obstructive pyelonephritis, in 73 of whom transcutaneous nephrostomy was applied and in 69--the ureter's stenting, for the urine passage restoration. The investigation was peformed in 1 month and 1 year after miniinvasive treatment. After comparison of the investigation results there was established, that after transcutaneous nephrostomy, using miniinvasive technologies, the affected kidney's functional inhibition was trustworthy less, than after stenting. Because of better preservation of renal function, the transcutaneous nephrostomy conduction in patients, suffering an acute obstructive pyelonephritis, constitutes a less invasive method, than the ureter's stenting.
