Morpho-Metrical Profile of the Kidney and the BMI Correlation in Normal Adults Metropolitans of Port Harcourt City, Nigeria

The Morpho-metrical profile of the kidney and the BMI correlation in Normal Adult is a study which determines the normal range of values of kidney dimensions in 202 healthy Port Harcourt metropolitans (102 male; 100 female) who were 20- 70 years of age. Mean age 46 ± 21.2 years; 46.3 ± 21.6 years (male), 45. 7 ± 20.8 years (female). Mean height: t 1.6± 0.1; 1.6m± O.lm(male), 1.5 ±0.lm(female). Mean weight: 70± 12.4kg; 72.8 ± 11.4kg (male); 67.4± 12.8kg (female). Mean body mass index (BMI [kg/m'[) 29.1 ± 7.8; 29.9 ± 12 (male), 28.4 ± 5 (female). The renal dimensions measured were length x width x cortical thickness which was established as equal to renal size. The mean kidney length 9.6 ± 0.4cm (right); 9.6 ± 0.4cm (left), kidney width 4.2 ± 0.3cm (right); 4.6 ± 0.2cm (left), cortical thickness 1.4 ± O.lcm; (right); 1.6 ± 0.2cm (left), kidney size 53 ± 9.9cm3 (right); 69 ± 9.lcm3 (left). Male kidney length were 9.8 ± 0.5cm (right); 9.9 ± 0.5cm (left), width 4.2 ± 0.4cm (right); 4.5 ± 0.4cm (left), cortical thickness 1.3 ± 0.2 (right); 1.6 ± 0.2cm (left) and kidney size 57 ± 12cm3 (right); 72 ± 17cm3 (left). Female kidney length was 9.7 ± 0.4cm (right); 9.7 ± 0.5cm (left), width4.2 ± 0.2cm (right); 4.6 ± 0.2cm (left), cortical thickness 1.4 ± O. lcm (right); 1.6 ± O. lcm (left) and kidney size 55 ± Scm' (right); 71 ± Scm' (left). There was significant difference between kidney length in male and female (p= <0.01). Kidney dimension measurement with ultrasound (US) is regarded as the most precise indicator of clinical diagnosis of hydronephrosis, nephritis and other renal pathologies.
