GUILLEN, R; RUIZ, I; VERA VIGO, P y OZUNA, R. Recurrent urolithiasis in a Miniature Schnauzerpuppy: Case report. Mem. Inst. Investig. Cienc. Salud [online]. 2011, vol.9, n.1, pp.49-53. ISSN 1812-9528.
The formation of urinary stones represents an important clinical issue in canines. There are differences in the trend to present urolithiasis among breeds. This is a case of recurrent lithiasis in a Miniature Schnauzermale puppy that presented hematuria and dysuria caused by a urinary tract obstruction associated to lithiasis. The puppy eliminated uroliths at the age of three and seven months old. The morphological analysis of this urinary calculus showed that the first consisted of carbapatite (crystallized carbonated apatite) classified as morphological type IVa1 and the second calculus presented a combination of type IVa1 + IIa. Morphological type IIa is formed by Weddellite (dihydrate calcium oxalate). Urine analysis of six samples showed a pH value from 6 to 7,5 with presence of bacteria and triple phosphate crystals in two samples and calcium oxalate crystals in one sample. Antibiotic therapy was applied to treat urinary infection in both lithiasic episodes. Dietary therapy consisted initially in feeding the puppy with balanced food special for dogs with lithiasis from two to seven months old. After the second lithiasic episode, the puppy was fed with boiled chicken and vegetables avoiding the balanced dog food. Since the implementation of the latter nutritional plan, more than a year ago, nor crystals have been detected in urine samples neither clinical signs of urolithiasis were observed in the puppy up to now.
