Introduction: Hypertension is one of the commonest non-communicable diseases worldwide; it is the sec-ond most common cause of end-stage renal disease.

Objective: To evaluate the renal dimensions and vol-ume of essential hypertension patients in Abubakar Tafawa Balewa University Teaching Hospital, Bauchi and to compare the dimensions with that of apparently healthy volunteers.

Materials and Methods: A total of two hundred and eleven individuals (comprising 121 females and 90 males) with essential hypertension attending an out-patient clinic in Abubakar Tafawa Balewa University Teaching Hospital Bauchi, and an equal number of healthy volunteers (comprising of 172 females and 49 males) were studied as controls. Both the healthy vol-unteers and the Hypertensive patients’ renal length, re-nal width, antero-posterior diameter, and parenchymal thickness were assessed. Statistical Package for Social Sciences (SPSS version 20.0) was used for data analysis.

Results: Study show the mean renal length for hyperten-sive patients to be 9.1 ± 0.79 cm and 9.1 ± 0.73 cm, the mean renal width of 3.5 ± 0.48 cm and 3.8 ± 0.68 cm, and mean renal volume of 87.22 ± 19.58 cm3 and 95.08 ± 22.93 cm3 for the right and left kidneys respectively. Results equally show statistically significant difference in anteroposterior diameter (p<0.05), parenchymal thickness (p<0.05) and re-nal volume (p<0.05) between the hypertensive group and the volunteer group for both right and left kidneys.

Conclusion: This study has established baseline renal dimensions for hypertensive in our population (Bauchi Metropolis). The hypertensive subjects showed a de-crease in renal anteroposterior diameter, parenchymal thickness and volume compared to control group.
