Forty-two patients were evaluated pre- and postextracorporeal shock wave lithotripsy (ESWL) using [99mTc]DTPA renography. A quantitative evaluation showed that the relative renal function decreased 2-3 days post-ESWL on the treated side, and the parenchymal transit time index (PTTI) increased 2-3 days post-ESWL (p less than 0.001) on the treated side and returned to the pretreatment level by 3 wk post-ESWL. The untreated side showed an increase in PTTI 2-3 days post-ESWL (p less than 0.01), which returned to normal by 3 wk post-ESWL. A significantly greater increase in PTTI was seen in patients who received greater than 1,000 shocks as compared with those who received less than 1,000 shocks. Five patients developed obstructing uropathy post-ESWL, when stone fragments caused ureteric obstruction.
42例患者在体外冲击波碎石术（ESWL）前后接受了[99mTc]二乙三胺五乙酸（DTPA）肾动态显像评估。定量评估显示，治疗侧肾功能在ESWL后2 - 3天相对下降，实质通过时间指数（PTTI）在ESWL后2 - 3天升高（p<0.001），并在ESWL后3周恢复至治疗前水平。未治疗侧在ESWL后2 - 3天PTTI升高（p<0.01），并在ESWL后3周恢复正常。与接受少于1000次冲击波的患者相比，接受超过1000次冲击波的患者PTTI升高更为显著。5例患者在ESWL后因结石碎片导致输尿管梗阻而发生梗阻性肾病。
