| PURPOSE : To evaluate changes of the high-resolution (HR) gray scale and Doppler ultrasonographic (US) characteristics
of experimentally induced acute uric acid (UA) nephropathy in rabbits.
MATERIALS and METHODS : Acute UA nephropathy was induced in ten rabbits using supersaturated lithium carbonate
solution. The rabbits were divided in two groups. Group I consisted of five rabbits, and they were injected with a
single dose of 150 ml of saturated UA over one hour. During this period, serial US studies of the kidneys of
these rabbits were performed every ten minutes. Group II consisted of the remaining five rabbits, and three injections
of 50 ml of saturated UA soultion were given on the first, fifth and eighth day and follow-up was done
upto twenty fifth day. Sequential HR and Doppler US, renal biopsy and blood sampling were performed on day
1, 5, 8, 21, and 25 in the group II rabbits.
RESULTS : In group I, HR and Doppler US examination revealed the normal resistive index without significant abnormality.
On the other hand, US studies of group II showed poor renal corticomedullary differentiation, decreased
renal blood flow and elevated resistive index. There was statistically significant correlation among US
findings, histologic characteristics and chemical index (BUN, creatinine) of renal function. In addition, sequentially
increased size and volume of the kidney were noted in both groups.
CONCLUSION : HR gray scale and Doppler US characteristics of experimentally induced acute UA nephropathy in
rabbits were similar to those of acute renal failure caused by other well-known causes. |
