Summary
Recurrent canine urolithiasis is common, with phosphate and cystine calculi being most frequent. Male dogs, particularly mixed breeds, Schnauzers, and Poodles, are most affected, often with urinary tract infections.
Area of Science:
- Veterinary Medicine
- Urology
- Canine Health
Background:
- Urolithiasis is a significant health concern in dogs.
- Understanding recurrence patterns is crucial for effective management.
Purpose of the Study:
- To analyze the incidence and types of recurrent urolithiasis in dogs.
- To identify risk factors associated with calculus recurrence.
Main Methods:
- Retrospective review of 438 canine case records from 1968-1974.
- Analysis of 561 urolithic episodes and 155 known recurrences.
- Categorization of calculus types and correlation with breed, sex, and bacterial cultures.
Main Results:
- 111 out of 438 dogs experienced 155 recurrent calculi episodes.
- Phosphate (54) and cystine (45) were the most common recurrent types.
- Male dogs predominantly had recurrences, except for 25 females with phosphate calculi.
- Urinary tract infections were common in dogs with phosphate and cystine calculi, with Staphylococcus linked to phosphate stones.
Conclusions:
- Recurrent urolithiasis in dogs is a notable issue, particularly for phosphate and cystine stones.
- Male dogs of mixed breeds, Schnauzers, and Poodles are at higher risk.
- Urinary tract infections play a role in the development of certain urolith types.
