从1989年3月至1990年5月行体外震波碎石术（ESWL）的病例中收集20例,分为经皮肾穿刺造瘘测压组（PCN组）和经膀胱输尿管逆行置管测压组（插管组）,观察其 ESWL时肾盂内压力的变化。结果显示:PCN组与插管组 ESWL时肾盂内压均较非ESWL时显著升高（分别为 P<0.01和 P<0.05）。文中还就ESWL中肾盂内压变化的意义进行了讨论,并提出了预防措施。
From March 1989 to May 1990, 20 patients underwent extracorporeal shock wave lithotripsy (ESWL) were divided into percutaneous nephrostomy manometry group (PCN group) and transurethral ureter retrograde catheterization manometry Group (intubation group), observation of ESWL when the renal pelvis pressure changes. The results showed that the intra-pelvic pressure of PCN group and intubation group were significantly higher than that of non-ESWL group (P <0.01 and P <0.05, respectively). The paper also discussed the significance of ESBL in renal pelvis pressure changes and proposed preventive measures.
