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.
慢性结石性肾盂肾炎（CCP）患者的上尿路引流不仅能成功进行抗炎和抗菌治疗，还能使体外冲击波碎石术（ESWL）更有效且安全。在21例通过导管支架进行上尿路引流的CCP患者中，使用Lithostar-Plus（西门子）进行ESWL。明显的脓尿、菌尿甚至中度上尿路扩张等活动性炎症是CCP患者在ESWL前及过程中进行导管支架上尿路引流的指征。导管支架上尿路引流有助于慢性肾盂肾炎的有效治疗，并能进行ESWL。拔除导管支架后既无急性肾盂肾炎发作，也无上尿路梗阻。导管支架可创建具有主动引流功能的封闭引流系统，其作用类似于生理状态。使用导管支架进行上尿路引流的患者进行ESWL更有效，并发症风险更低。
