[Urodynamics of the upper urinary tract in urolithiasis patients with chronic pyelonephritis].

Urodynamics was studied in patients with chronic pyelonephritis with a various level of upper urinary tract (UUT) obstruction. 90% patients with concrements of the low ureter had high intrapelvic pressure (IPP)--21.8 +/- 0.8/25.2 +/- 0.8 cm of water column (basal/peristaltic) and enhanced UUT contractility. IPP was elevated in 50% patients with proximal UUT… CONTINUE READING
