Are the Stone Density and Location Useful Parameters for Small Kidney Stones?

Abant Izzet Baysal University60 enrolled

Overview

The investigators aimed to evaluate whether these parameters could be guides for us in the selection of RIRS or Mini-PNL procedures in kidney stones that are smaller than 2 cm. The patients that have kidney stones smaller than two cm and be planned to undergo surgery were randomized into 2 groups prospectively. RIRS was performed in the RIRS group using a 7.5-F fiberoptic flexible ureterorenoscope while Mini-PCNL group was dilated up to 16.5F and mini-PCNL was performed with 12F nephroscopy. Preoperative characteristics, operative and postoperative results were compared in two groups. Thereafter, intra and intergroup comparisons were made to determine the effects of HU value, indicating the stone density, higher or less than 677 and the stone location on stone-free rates.

Inclusion Criteria: * Patients were evaluated with non-contrast abdominopelvic CT after a detailed anamnesis and physical examination. * Patients, who had a kidney stone with a maximum diameter of less than 2 cm and who did not prefer to undergo ESWL, were taken into the study. Exclusion Criteria: * Patients with anomalous kidneys, skeletal deformities, severe obesity (BMI\> 35) and those underwent ESWL treatment previously for the same stone were excluded from the study.
