Summary
Kidney dimensions in Nepalese adults are shorter and lighter compared to global averages. These findings provide crucial morphometric data for kidney ultrasonography in Nepal.
Area of Science:
- Anatomy
- Anthropology
- Radiology
Background:
- Kidney dimensions are established globally via ultrasonography and morphometry.
- No prior morphometric data exists for the Nepalese population.
- Understanding local kidney dimensions aids diagnostic accuracy in Nepal.
Purpose of the Study:
- To establish baseline kidney dimensions (length, width, thickness, weight) in adult Nepalese kidneys.
- To compare these dimensions with existing global data.
- To provide essential reference values for Nepalese ultrasonologists.
Main Methods:
- Morphometric analysis of 40 formalin-preserved adult kidneys (age/sex unknown).
- Measurements included maximum length, width, and thickness using a sliding caliper.
- Kidney weight was determined using a precision balance; statistical analysis employed Student's t-test.
Main Results:
- Average right kidney dimensions: 85.25mm (length) x 50.65mm (width) x 34.6mm (thickness); weight: 84.16g.
- Average left kidney dimensions: 91.65mm (length) x 53.65mm (width) x 38.5mm (thickness); weight: 111.1g.
- Nepalese kidneys were significantly shorter, lighter, and thicker than global averages, with significant left-right differences in length, thickness, and weight.
Conclusions:
- Nepalese adult kidneys exhibit distinct morphometric characteristics compared to other populations, potentially due to racial variations.
- The left kidney is consistently larger and heavier than the right kidney in the Nepalese population.
- These findings are vital for accurate interpretation of renal ultrasonography in Nepal.
