Objective: Aim of our study was to examine the patients presenting with urolithiasis and the relationship of the incidence of clinically significant hydronephrosis in patients with and without microscopic hematuria.
Methods: This is a prospective study of 180 patients who presented to the emergency department with ureteric calculus during the period of December 2018 – May 2019 (6 months) in the Department of Urology, Government Kilpauk Medical College, Chennai. All patients who met the inclusion criteria underwent non-contrast computed tomography of the abdomen and pelvis and urinalysis. We compared the mean stone size and the severity of obstruction found on imaging in patients with and without microscopic hematuria on urinalysis
Results: In our study a total of 180 patients who met the inclusion criteria were included. Out of these, 134 patients (74%) had microscopic hematuria on urinalysis. Patients with negative microscopic hematuria had severe obstruction with Grade II -III hydronephrosis and the mean stone size was higher.
Conclusions: Patients with ureterolithiasis in absence of microscopic hematuria on urinalysis are at increased risk of having severe obstruction in comparison to those with microscopic hematuria.
