Background: Urolithiasis is the third most common urological disease. The prevalence is on the rise due to various
changes in the socio-demographic and other etiological factors in the north-eastern states of India in general and
Manipur in particular.
Aims & Objective: The study was conducted to determine the prevalence of urinary stones and to assess the
association between urolithiasis and selected variables of interest.
Material and Methods: The study was conducted during September 2008 to August 2010 among wetland dwellers of
Loktak Lake in Thanga, a rural area of Manipur. A representative sample of subjects, which included men and women
15 years of age and above were included in the study. Sample size was calculated based on a prevalence rate of 5.41%
with an allowable error of 1.5 at 95% confidence level. Calculated sample size was 875. A pre-tested interview schedule
was used for data collection.
Results: A total of 875 individuals were studied. The prevalence rate of urolithiasis was 196(22.40%) and was more
commonly present in the age group of 25-44 years. Urolithiasis was observed to be significantly more common among
those individuals who are more educated, engaged in heavy work, with history of urinary tract infection (UTI), with
history of stressful events in recent years, among those who consumed only 2-4 glasses of water per day and with
family history of stones.
Conclusion: Prevalence of urolithiasis was observed to be 196(22.4%). Information regarding the risk factors which
have been identified in the present study can be utilized in formulating future health plans for preventive services.
