Main Article Content
Abstract
Background: Urolithiasis, a prevalent urological condition, especially in areas with warm and dry climates, poses significant healthcare challenges. In Pakistan, part of the "stone-forming belt," the incidence of urolithiasis is consistent with global prevalence rates. Understanding the demographic and clinical presentation patterns is essential for improving diagnostic and treatment strategies.
Objective: The study aimed to determine the prevalence and characteristics of asymptomatic urolithiasis in adult patients and to evaluate the efficacy of multidetector computed tomography (MDCT) in detecting urinary tract stones and associated abnormalities.
Methods: This cross-sectional study was conducted over four months at the University of Lahore Teaching Hospital's Radiology Department. A total of 112 adult patients aged between 18 to 70 years with symptoms indicative of urinary tract abnormalities were included using a convenience sampling technique. Siemens 64-slice MDCT was employed for diagnosis. The chi-square test and Fisher's Exact Test were utilized for statistical analysis to assess the association between urolithiasis and clinical symptoms, with p-values less than 0.05 considered significant.
Results: Out of 112 patients, the prevalence of asymptomatic stones was 2.8%. Bladder stones were identified in 16 patients (14.3%) with a size range of 3-12 mm (mean 7.5 mm, S/D ratio 2.6). Ureteric stones were found in a subset of patients, with sizes ranging from 6-28 mm (mean 13.8 mm, S/D ratio 4.1). The prevalence of hydronephrosis was 39.9% for the left kidney, 26.1% for the right kidney, and 10.9% for bilateral presentation. Non-stone-related findings requiring treatment were identified in 14% of patients undergoing MDCT for renal colic.
Conclusion: The study confirmed the prevalence of urolithiasis within the expected range for a high-risk geographic area. MDCT urography proved to be a valuable diagnostic tool in detecting not only urolithiasis but also other significant renal tract abnormalities. The results indicate a need for improved public health strategies, particularly for the at-risk older adult population.
