Shcherbak D. Prognostication of function-restorative possibilities of the blocked ren and tactic of treatment at urolithiasis.

Owing to the new algorythm it becomes possible to objectively estimate function-restorative possibilities of blocked ren at urolithiasis and make choice of rational tactic for treatment. Presented are the results of examination and treatment of 156 patients with blocked ren at urolithiasis. It has been discovered that phenomena of nephropathy arises after 6 hours from beginning of the block and achieves its maximum level after a period of obstruction from 3 to 10 days. Observation of blood stream in staggered ren at sharp violation of urodynamics like kidney colic led to this conclusion. After 10 days of obstruction decline of kidney filtration was noticed. It indicated negative prognostic criteria for probability of self-dependent discharge of concrement. No change to Index of Resistance has been found that would depend on duration of obstruction in condition of a chronical disorder of urodynamics. It had been proved that indexes of the two renal specific enzymes activity are well-proven. We discovered a linear dependency between the activity of the N-acetyl-beta-D-glucosaminidasa and beta-galactosidase and the duration and completeness of the block.
