A prospective study was performed to compare the efficacy of plain X-ray, renal tomography and renal ultrasound for the evaluation of the presence of residual fragments and the size of the fragments on 108 patients at 1 month follow-up after ESWL. Ultrasound appeared to be sensitive in identifying the residual fragments. Renal tomography more specific in the evaluation fragment size. We suggest that the one month follow-up evaluation could be limited routinely to ultrasonography and abdominal X-ray. However in some selected patients renal tomography should be performed to confirm and evaluate the presence and size of residual stone fragments.
