Usefulness of renal length and volume by ultrasound in determining severity of chronic kidney disease

Abstract EN

To determine the correlation of renal ultrasonic parameters and degree of kidney function among chronic kidney disease patients seen at the Nephrology unit of the University of Ilorin Teaching Hospital (UITH) Ilorin, we studied 322 patients.

The results were analyzed with specific reference to socio-demography and correlating renal length and volume with estimated glomerular filtration rate.

The male to female ratio was 2:1, with an age range from 20 to 80 years and mean age of 45.06 (±13.0) years.

The serum creatinine levels ranged from 201 to 1205 μmol / L, with a mean of 388 ± 168 μmol / L, while the estimated glomerular filtration rate (eGFR) ranged from 3.77 to 44.32 mL / min, with a mean of 18.2 ± 7.19 mL / min.

The right and left renal lengths ranged from 6.9 to 13.0 cm, with a mean of 9.11 ± 1.06, and 6.5-13.4 cm, with a mean of 9.23 ± 1.07 cm, respectively.

The mean volumes of the right and left kidneys were 98.6 ± 41.9 cm3 and 105 ± 46.2 cm3, respectively.

The Pearson correlation of the right and left kidneys length to eGFR were -0.197 and -0.137 respectively, while that of the right and left kidney volume to eGFR were -0.122 and -0.043, respectively.

Our study showed that there is a positive correlation between ultrasonic renal measurements and degree of kidney function.
