Abstract
ABSTRACT
Background
Types of renal stones have profoundly changed in the last half-century, parallel to
the change in lifestyle and dietary habit, with an increase of calcium stones. Among
many lithogenic factors age and gender are considered to be associated with the
types of renal stones. Studies evaluating the influence of age and gender on the
distribution of the types of urinary calculi are scarce in Nepal.
Objective
To explore the influence of age and gender on different types of urolithiasis.
Method
This is a single center prospective study encompassing urolithiasis during a study
period of 18 months. All the stone retrieved from the patients after surgery were
sent for biochemical analysis of the stone. The result was then compared with the
age and gender of the study population.
Result
Calculi from a total of 107 patients wereanalyzed (62 from malesand 45 from
females). Mixed stones consisting of calcium oxalate and calcium phosphate werethe
predominant constituent in 74.16% of stones, followed by uric acid, struvite and
cystine stones. We found predominance of Calcium stones in males(47.66%) vs
36.44% in females and predominance of struvite stonesin females (7.47%) vs 3.73%
in males. Age group of 21-40 years has the main burden of stone.
Conclusion
Being aware and having better knowledge of risk factors, composition and correlation
with age and gender can provide personalized guidance to prevention and avoid
recurrence of urolithiasis.
