This study is standard surgical measurement of the size of kidney in normal Ksorean population that might be basic datas of re4nal size in comparison with radiographic and ultrasongraphic measurement for clinical implies.
The 235 cases of donors for renal transplantation were measured by the length, width, thickness, weight and the outer diameter of renal vessels as well as identification of branfches of renal vein at the time of donor nephrectomy. These data were
tested
to be statistically significant by Ttest, AkNOVA, Pearson correlation analysis and multivariate analysis.
The mean values of renal size were 11.6±0.87 (9.2-15l.4cm)×6.1±0.81 (4.4-10.0cm)×4.9±0.75(2.2-7.1cm) : for male 11.7±0.77 (9.8-14.0cm)×6.2±0.85 (4.5-10.0cm)×5.0±0.77( 2.8-7.1cm) and for female 11.4±0.96 (9.2-15.4cm)×6.0±0.75
(4.4-8.2cm)×4.8±0.7(2.2-7.0cm). The mean value of renal weight were 183.1±36.92 (115.0-370.0gm) : for male 188.2±40.10 (120.0-370.0gm) and for female 177.6±32.41 (115.0-300.0gm). The width, thickness and weight of kidney were largerin male
than in
female (p<0.05).
I found out that the age of donors did not affect the renal lenght, width, thickness and weight (p>0.05). The renal lenght, width, and weight increased proportional to the body weight (p<0.05). The renal thickness and weight were different in
each
range
of the body height (p<0.05). T body weight had correlation with renal lenght (r=0.26), thickness (r=0.32), weight (r=0.36, p<0.001) and width (r=0.16, p<0.05). The body weight was the most reliable factor affecting renal size and weight in
multivariate
analysis (p<0.05).
The mean number of branches of renal veein was 0.36±0.63 (0.0-2.0) in right kidney and 3.12±0.76 (1.0-6.0) in left o ne. The man diameter of the renal artery was 0.61±0.132 (0.3-1.0cm) and the mean diameter of the renal vein 1.46±0.132
(0.50-2.20cm). The radiographic measurement of renal size was larger than our surgical measurement. The mcan renal length and width I n radiographic measurement (TVP) were 12.1±0.70cm in right kidney, 12.1±0.66cm in left one and 6.4±0.54cm in
nght
kidney, 6.8±0.45cm in left one versus 11.6±0.87cm, 11.6±0.89cm and 6.1±0.81cm, 6.1±0.84 cm in surgical measurement.
Ssurgical measurements of renal size of donors at the time fo renal transplantation were real renal size despite of radiographic and ultrasonographic measurement and provided basdic standard data for Korean population that migtht be utilized in
approaching renal disease.
