Chemical analysis of urinary calculi in Haryana
Insights
This study analyzed 225 urinary calculi, finding calcium oxalate monohydrate (CaOxM) as the primary component in all stones. Different stone types showed varying concentrations of other minerals, impacting their location and composition.
Area of Science:
- Urology
- Nephrology
- Analytical Chemistry
- Materials Science
Background:
- Urinary calculi (kidney stones) are a significant health concern.
- Understanding the chemical composition of urinary stones is crucial for diagnosis and treatment.
- Regional variations in stone composition may exist due to environmental and dietary factors.
Purpose of the Study:
- To quantitatively analyze the chemical composition of urinary calculi from Haryana, India.
- To determine the prevalence of major mineral components in renal, bladder, and ureter stones.
- To investigate variations in stone composition based on anatomical location.
Main Methods:
- Quantitative chemical analysis was performed on 225 urinary calculi samples.
- Samples were collected from renal, bladder, and ureter locations across different districts of Haryana.
- Prevalence and concentration of key components like calcium oxalate monohydrate (CaOxM), magnesium ammonium phosphate (MAP), hydroxyapatite (HA), calcium apatite (CA), and uric acid (UA) were determined.
Main Results:
- Calcium oxalate monohydrate (CaOxM) was the major component in all analyzed stones.
- Magnesium ammonium phosphate (MAP), hydroxyapatite (HA), calcium apatite (CA), and uric acid (UA) were present in 83.7%, 83.6%, 13%, and 78.9% of cases, respectively.
- Renal stones had higher CaOxM content, bladder stones showed higher MAP and UA content, and ureter stones had higher HA content.
Conclusions:
- The study reveals a high prevalence of CaOxM in urinary calculi from Haryana.
- Significant variations in the concentration of MAP, HA, and UA were observed based on stone location (renal, bladder, ureter).
- These findings contribute to understanding the geographical and anatomical influences on urinary stone composition.
Abstract:
Quantitative chemical analysis of 225 urinary calculi (128 Renal, 57 bladder and 40 ureter) collected from hospitals of different districts of Haryana was carried out. CaOxM was found to be present as a major component in all the stones analysed, while MAP, HA, CA and UA were found in 83.7%, 83.6%, 13% and 78.9% cases, respectively. The content of CaOxM was found to be higher in renal stones as compared to ureter and bladder stones, while the concentration of MAP was higher in bladder stones as compared to kidney and ureter stones. HA content was higher in ureter and UA was higher in bladder stones as compared to other urinary stones.
