title: [Drainage of the urinary tract as preparation for extracorporeal lithotripsy].
abstract: Upper urinary tract drainage in patients with chronic calculous pyelonephritis (CCP) results in not only successful anti-inflammatory and antibacterial treatment but also in more effective and safe ESWL. In 21 CCP patients with upper urinary tract drainage by means of catheter-stent, ESWL was performed using Lithostar-Plus (Siemens). Active inflammation with marked pyuria, bacteriuria and even moderate upper urinary tract dilation were indications for the upper urinary tract drainage with catheter-stent before and during ESWL in CCP patients. Upper urinary tract drainage with catheter-stent contributed to effective treatment of chronic pyelonephritis and allowed to perform ESWL. There were neither attacks of acute pyelonephritis nor upper urinary tract obstruction after catheter-stent removal. The catheter-stent allows to create closed drainage system with active evacuation function as it functions in physiological conditions. ESWL in patients with upper urinary tract drainage using catheter-stent is more effective and has lower risk of complications.
