Background: Sonographic measurement of renal size is an important parameter in the clinical evaluation of renal pathologies. No information yet exists on renal size and its relationship to age and sex in the middle aged and elderly (>50yrs) in Enugu, South East Nigeria. The aim of this study is to determine variations in renal size and its relationship to age and sex in the aging population using absolute renal length as a parameter. Method: This is a retrospective study where a cross section of 200 subjects between the ages of 50 and 89 years were scanned between the years 2008 and 2010. These had no history of renal disease and showed normal renal features on ultrasonography, Absolute renal length was measured using real-time ultrasonography and a 3.75MHz probe. Results: 200 adults (122 males and 78 females) between 50 and 89 years (64.7± 9.7lyears) were evaluated. Kidney length was significantly longer in males than in females (P <0.01). Kidney length showed a decrease length with increasing age, the rate of decrease accelerates above 60years. No significant difference was seen between the left and right kidney length (104 ± 11.0m left kidney vs 103 ± 10.8m right kidney; P> 0.05) Conclusion: This study shows the effect of age on renal length in subjects above 50years in Enugu.
