Introduction: Our study aims to validate the clinical research office of the Association of Endourology, which is used to predict the success of treatment and complications rates in patients with percutaneous nefrolithotomy (PNL) (CROES). Instruments and Methods: Between January 2012 and August 2015, 568 patients applied PNL in the Izmir Bozyaka Education and Research Hospital Urology Clinic were evaluated as retrospective. Two (two) and more of these patients were not included in the study. All patients were assessed with non-contrasted spiral computer tomography (BT) prior to surgery. Patients were evaluated in the postoperative 1st month check with direct urine system graphics (DÜSG). Symptomatic patients, patients with non-optic stone and/or suspicious opticity in DÜSG were assessed with uncontrasted BT. The remaining stones of less than 4 mm identified in DÜSG or BT were clinically unimportant and were considered to be stone-free in these patients. The CROES score system was applied individually to each patient. This scanning system correlated the stone-free rates, operating times, scoping times, hospitalization times and the estimated amount of blood loss. Postoperative complications were calculated according to the modified Clavien score system and correlated with the CROES stone score system. Results: The average CROES stone score was 203.70. The number of patients diagnosed with insomnia was 394 (77.9%). The average stone size was calculated as 502,01 ± 517,5 (55-2869) mm2. The remaining stone was detected in 112 (22.1%) of the patients applied to PNL. The total number of patients observed the complication was 159 (32.5 percent). A positive correlation between the CROES score and stone loss (p<0,01) was detected, while a negative correlation between the development of complications (p=0,001) was detected. The CROES score also observed a negative correlation between the duration of the operation (p<0,001), the duration of the hospital stay (p=0,026), the amount of bleeding (p=0,007) and the stone load (p<0,001). In multiple variable analysis, CROES score was determined as an independent factor in the forecast of stone. (p<0,001) The complication forecast found that the CROES score was not an independent factor. Result: Our study has shown that the CROES scored system is an effective and reliable scored system. It is also an effective scoring system in the prediction of postoperative complications. The CROES score system can guide clinics in forecasting perioperative and postoperative results.
