SDMA appears to be a useful marker of post-renal azotemia in cats with UO, and pre-decompression SDMA does not reflect underlying kidney disease. UTIs may be more frequent in cats with UO than historically suggested, and screening should be considered, especially if SDMA and creatinine concentrations are elevated. Seventeen cats were identified for inclusion in the study. The median age was 12 years (range 3-17 years). Spayed females (n = 14) were more prevalent than castrated males (n = 3). Anorexia (7/17), lethargy (6/17) and vomiting (5/17) were the most common presenting complaints. Common physical exam abnormalities included muscle wasting (8/17), hypothermia (6/17) , and cardiac murmurs (6/17) . Clinical signs classically associated with pyelonephritis, such as renal pain and pyrexia were present in only 3 and 2 cats, respectively. Serum chemistries and complete blood counts were available for 11 and 10 cats, respectively. Common clinical pathologic abnormalities included azotemia, hyperphosphatemia, and non-regenerative anemia in 11, 8 and 7 cats, respectively. Of the 5 cats for which urinalysis data was available, all had bacteriuria and 4 had isosthenuric urine. Of the cats that had a urinalysis performed, four also had urine samples submitted for culture. Subcutaneous ureteral bypass (SUB)â„¢ device placement is an alternative to traditional ureteral surgery. However, outcomes have not been described for treatment of benign ureteral obstructions in dogs. The purpose was to evaluate pre-operative, peri-operative (< 7 days), short (7-30 days) and long-term (> 30 days) parameters in dogs treated with SUBsâ„¢ for benign ureteral obstructions. The hypothesis was SUBsâ„¢ were associated with favorable technical outcomes when compared with alternatives.
