Introduction & Objectives: In this study, we aimed to compare the preoperative and peroperative results of the patients with urinary system stones and the patients with a history of intervention.

Materials & Methods: Between October 2018 and January 2019, 152 primary patients who were operated for urinary tract stones in both centers and who had no history of ESWL or stone surgery were included in Group I and 232 patients with a history of intervention were included in Group II.

Results: Demographic characteristics were similar in two groups. The low socioeconomic level and low level of education were the majority in both groups. The number of CT imaging performed in the last 1 year was statistically higher in secondary patients (p <0.001) (Table 1). In Group I, ureteric stones constitute the majority; In Group II, kidney stones were statistically higher (p <0.001). The number of stones was lower in primary patients (1.40 ± 0.80 / 2.05 ± 1.40, p <0.001). The dominant procedure was URS in Group I and RIRS in group II (p <0.001). The success rate of the primary patients was statistically higher (p = 0.015). Postoperative medical treatment was higher in secondary patients (p <0.001) (Table 2). No statistical difference was observed between the two groups in terms of nutritional habits such as water, tea, coffee, soda, alcohol, protein and salt consumption. While both groups are similar in terms of physical activity habit; smokers had a higher rate in Group II (44.1% / 52.2%, respectively, p = 0.044).

Conclusions: Approximately half of the patients with urinary system stone face this situation again throughout their lives. As in our study, the number of stones and the more proximal stones are in the more risky groups for recurrence. In recent years, increased use of stone protocol CT was found to be higher in secondary patients. Previous stone history was thought to be effective in this. The success rate of primary patients was found to be higher due to the location of the stone, which was more distal, which was easier after the fragmentation.
