We aimed to determine whether there was a relationship between the perception of renal colic pain and different psychosocial and physiological factors. Between May 2021 and July 2022, we prospectively analyzed 320 patients who were diagnosed with renal colic occurring unilaterally and secondary to a single kidney stone of any size, over the age of 18. Body mass index (BMI), education level, hospital anxiety and depression scale (HADS), somatosensory amplification scale (SAS), and the visual analog scale (VAS) features of stone (diameter, Hounsfield value, and localization) and degree of hydronephrosis were analyzed. Correlation analysis of VAS score and these parameters were completed with Spearman's test. The regression analysis was used to determine the predictive factors of severe pain. There was no significant difference found between sex and VAS scores of colic pain (p=0.122). We found a significant correlation between VAS score and localization of kidney stone, degree of hydronephrosis, and anxiety level of patients. High grade of hydronephrosis and high anxiety level were found to be associated with high VAS scores (p<0.001 and p=0.035, respectively). It was shown that SAS and level of depression did not correlate with pain. Only a high degree of hydronephrosis was found to be a predictive factor for severe pain (p<0.01).Conclusıons:The patient's high anxiety level and a high degree of hydronephrosis were positively correlated with renal colic pain caused by kidney stones. With this study, the severity of pain in patients with a high degree of hydronephrosis and high anxiety can be predicted and may be a criterion to select suitable treatment to reach faster response.
