Abstract:
Objective To study the impact of preprocedure intravenous urography (IVU) on the extracorporeal shock wave lithotripsy(ESWL) for proximal ureteral stones.Methods One hundred patients with solitary radiopaque proximal ureteral stones on plain radiographs and no severe hydronephrosis on ultrasonographic examination were allocated randomly to two treatment groups.IVU group (n=50) had IVU before the start of ESWL,whereas patients in control group (n=50) underwent ESWL without IVU.Postop- erative success,the stone-free rates and complications were evaluated in both groups. Results Seven patients in IVU group were excluded from the study. The success rate [95.3%(41/43) in IVU group vs 94.0% (47/50) in control group],stone-free rate [83.7% (36/43)vs 86.0% (43/50)] and complication rate[27.9% (12/43 ) vs 26.0% (13/50)]were similar in two groups (P＞0.05).Conclusions It is not necessary to obtain an IVU for patients who have solitary radiopaque proximal ureteral calculi on plain radiographs with no severe hydronephrosis on uhrasonographie examination before scheduling them for ESWL,thus minimizing the cost,avoiding exposure to contrast medium,and reducing radiation exposure.
