2018 ACVIM Forum Research Abstract Program: Seattle, Washington, June 14 - 15, 2018

Dogs were included in this study if CaOx urolithiasis was confirmed via quantitative calculi analysis and ionized calcium (iCa), routine serum chemistry, CBC, and urinalysis were available for evaluation. Dogs were divided into hypercalciuric andnonhypercalciuricstoneforming groups. Mann-Whitney test was used to compare groups. were renal-related deaths (RD). RD and AC dogs in IRIS stage 3 or 4 at biopsy had significantly shorter survival post -biopsy (SPB) than those in IRIS stage 1 or 2 (RD p < 0.001; AC p < 0.001). RD and AC dogs with Alb < 2 g / dL had significantly shorter SPB than dogs with Alb > 2 g / dL (RD p = 0.01; AC p = 0.004). RD and AC dogs with ascites / edema at time of biopsy had significantly shorter SPB compared to dogs without (RD p = 0.001; AC p = 0.03). AC dogs with history of HT had significantly shorter SPB compared with AC dogs without a history of HT (p = 0.03). RD dogs with GS affecting ≥ 25 % of glomeruli had significantly shorter SPB than RD dogs with < 25 % GS (p = 0.03). UPC was not significantly associated with SPB in RD or AC dogs.
