Predictive factors for stone disease in patients with renal colic.

Abstract

Many patients present to urology and emergency departments for acute renal colic complaints. There are many different imaging studies that can be used in patients with a pre-diagnosis of acute renal colic. In this study, we would like to assess the efficacy of using clinical and laboratory results in patients with flank pain complaint as a predictive factor of urinary system stone disease. All patients were assessed using spinal non-contrast complete abdominal computerized tomography and urine analysis. Presence of stones and their number and size were recorded. 516 patients who were included in the study were divided into 2 groups according to urinary stone presence. Group 1 (n = 388) consisted of patients with stones meanwhile patients in Group 2 (n = 128) were stone-free. According to these results, male sex, presence of microscopic hematuria, stone history in the family, nausea and emesis in addition to pain and accompanying urinary symptoms were detected as predictive factors in diagnosing urinary stone disease by multivariate analysis. From our study results, we can conclude that uroflowmetry is a very useful tool in monitoring lower urinary system complaints.
