Abstract:
Background: Renal stone disease is a significant illness with a massive impact on patients. Data
relating to the profile of renal stone patients in the central province of Sri Lanka is limited, despite
the growing prevalence of the illness. This research study aimed to bridge this gap through
analysis of the renal stone patients who attend the urology clinic at National Hospital, Kandy.
Objective: To identify the demographic, clinical, laboratory, and imaging characteristics of
patients with renal stone disease attending the urology clinic, National Hospital, Kandy
Methods: A total of 110 patients with renal stones participated in this descriptive cross-sectional
study. The socio-demographic characteristics, clinical presentation, laboratory and imaging
findings, and morphological features of the renal stones were collected using an interviewer-
administered questionnaire and clinical records. SPSS version 26.0 was used to perform statistical
analysis.
Results: The majority of renal stone patients were males (74.5%), with Sinhalese being the
predominant ethnic group (80.9%) and the mean±SD age being 47.1±13.5 years. The most
common symptoms reported by patients were pain (91.8%) with dysuria and lower urinary tract
symptoms, as reported by 60% and 46.4% of all participants, respectively. Hypertension (66.4%)
and diabetes (64.5%) were seen to be the most common comorbidities. Urinalysis was ordered for
68.2% of all patients, and imaging modalities primarily involved ultrasonography (91.8%). Renal
stones were most frequently located at the right renal calyx (49.1%) and pelvis (28.2%). The
mean±SD stone size was 9.4±6.1 mm.
Conclusion: This study underpins the characteristics of renal stone patients in a selected Sri
Lankan cohort, highlighting the role of demographic features, comorbidities, and laboratory and
imaging protocol. The findings of this study provide important information which can be utilized
for improving diagnosis, prevention and management strategies that are tailored to target the
population
