Abstract
Aim: To define the value of different radiologic modalities in determining the patients who believed to be stone-free after extracorporeal shock wave lithotripsy (SWL) with plain abdominal X-ray, by evaluating the same patients with ultrasonography (USG) and helical computed tomography (CT). Patients and methods: Between March 2002 and February 2003, 76 patients with urolithiazis who were treated with SWL and considered to be stone-free with plain abdominal X-ray, were evaluated with USG and helical CT. The results were compared for the accuracy of the stone-free diagnosis. Results: Residual stones were detected in 9 (11.8%) with USG and in 17 (22.3%) with CT of 76 patients who were thought to be stone-free with plain abdominal X-ray alone. Conclusions: Although plain abdominal X-ray has been accepted as the first line diagnostic tool in the follow-up after SWL with its cheap and practical use, helical CT was found to be more valuable in diagnosis of residual stone fragments which has not been found in plain abdominal X-ray. If we take these considerations which can change our clinical approach and patient follow-up into account, we believe that the routine use of helical CT can give more accurate information in patient controls after SWL.
