Summary

Residual fragments of urinary calculi after flexible ureteroscopy (URF) can cause symptoms and additional surgeries. The assessment of residual fragments by imaging is not standardized. Computed tomography (CT) is the best way for evaluation of urinary stones, however, ionizing radiation from CT is deleterious. The aim of this study is to define which patients may avoid CT for evaluation of residual fragments after URF. 115 patients with \> 18 years old undergoing URF for kidney stone \< 20 mm or \< 15 mm in the lower calyx diagnosed by CT will be studied. The clinical evaluation of patients will be held by the same urologist in pre-operative consultation, 7 days after the procedure, 30 days after the procedure and 100 days after the procedure. The assessment of residual fragments will be made through TC, ultrasound and Kidney-bladder-ureter KUB 90 days after the procedure. The image methods for residual fragments assessment will be compared by Cochran Test and prediction of parameters to avoid CT will be made by multiple logistic regression, using IPSS 16.0, with significant level of 5%.
