Introduction: Hyperuricemia is associated strongly with the development of renal disease and progression. Medical therapy decreases serum uric acid levels by inhibiting the enzyme xanthine oxidase.

Objective of the study: To evaluate correlation of mean uric acid level and Renal Resistive Index in normoglycemic and normotensive adult subjects.

Material and methods: This descriptive cross-sectional study was conducted in THQ Hospital Fort Abbas during 31-10-2018 to 30-04-2019. One hundred (n=100) non-diabetic, non-hypertensive, recently diagnosed hyperuricemic otherwise healthy subjects irrespective of gender between age 20-40 years were included in the study.  After complete history taking and full physical examination laboratory testing including: serum uric acid, serum creatinine to exclude renal decompensation patients, fasting blood sugar and 2 h post prandial were advised.

Results: 55.0% (n=55) of patients were males with the mean age of 33.40 years ± 3.85 SD and 45.0% (n=45) of patients were females with mean age of 34.67 years ± 3.33 SD. Cumulative mean age was 33.97 years ± 3.66 SD. The mean value of the RI of the renal arterial vasculature was 0.765 ± 0.0155 SD. The maximum, minimum and range values of the RI were 0.79, 0.74, and 0.04 respectively. The mean serum uric acid value found to be 10.947±0.562 SD. The maximum, minimum and range values of the RI were 0.79, 0.74 and 0.05 respectively. Correlation between the serum uric acid and renal arterial RI prior to the medical therapy and 3 weeks after therapy. A positive correlation was found between both values with a Pearson’s correlation coefficient = 0.103 and p-value 0.308.

Conclusions: It is concluded that that medical treatment of hyperuricemia results in lowering of serum uric acid which correlates with the decrease in renal resistive index.
