The mean creatinine clearance in the CRF and control groups was 9.8 + 6.7mls/min and 126.2 + 7.4 mls/min respectively. There was a statistically significant difference between

Table 4 shows the distribution of subjects according to creatinine clearance. In the CRF group, 47 (90%) had ESRD, with creatinine clearance < 15mls/min, 4 (8%) had creatinine clearance of 15 – 29mls/min, and 1 (2%) had creatinine clearance 30 – 59mls/min. All

The mean kidney sizes in the CRF group was 8.2 + 0.5cm and 8.3 + 0.5cm for the right and left kidneys respectively, while that of the control was 12.10 + 0.33cm and 12.02 + 0.33cm for the right and left kidneys respectively. 52 (100%) patients in the CRF group had shrunken kidneys (<11cm).

There was a weak positive correlation between renal sizes and creatinine clearance, with r = 0.12 and r = 0.17 for the right and left kidneys respectively (see Table 5).
