From January 1990 to December 2010, 4,872 dogs were necropsied at the Laboratório de Patologia Veterinária, Universidade Federal de Santa Maria. Seventy six dogs (1.6%) had uroliths along the urinary tract. The epidemiological profile of the affected dogs showed predominance of males (64.5%); adults (52.6%); and pure breeds (56.6%). Clinical signs suggestive of urolithiasis were reported in 30.3% of the dogs and consisted mainly of hematuria, anuria, dysuria and urinary incontinency. The uroliths were found in one or more anatomical sites, and the main affected ones (in descending order) were urinary bladder, kidney, and urethra. Ureteral urolithiasis was not observed. Secondary lesions to urolithiasis were found in about 40% of the cases. The most prevalent (in descending order) were cystitis, urethral obstruction, hydroureter, hydronephrosis, urinary bladder rupture (with uroperitoneum), and pyelonephritis. In 25% of the affected dogs, spontaneous death occurred or euthanasia was performed due to the secondary lesions of urolithiasis. Extra-renal lesions of uremia were found in 11.8% of the cases. |
