Extracorporeal piezoelectric lithotripsy (EPL) is frequently used to treat renal calculi. We are presenting a case that developed silent ureteric obstruction following three sessions of EPL of 4,000 shocks each. The obstruction was silent and asymptomatic, and was detected 6 weeks later on a routine follow-up renogram. The obstruction was due to an impacted stone fragment in the lower ureter. After release of the obstruction, the kidney function did not return to pre-therapy levels due to irreversible damage. This case demonstrates the importance of doing renograms before and within a few days after shock therapy for renal stones.
体外压电碎石术（EPL）常用于治疗肾结石。我们报告一例在进行了三次每次4000次冲击的EPL治疗后出现无症状性输尿管梗阻的病例。梗阻是无症状的，在6周后的常规随访肾图检查中被发现。梗阻是由于输尿管下段有一块嵌顿的结石碎片所致。梗阻解除后，由于不可逆转的损害，肾功能未恢复到治疗前的水平。该病例表明在肾结石冲击治疗前及治疗后几天内进行肾图检查的重要性。
