Diagnosis and treatment of urolithiasis in client-owned chelonians: 40 cases (1987-2012).

Objective: To calculate the prevalence of urolithiasis in client-owned chelonians examined at a veterinary teaching hospital and to describe the clinical signs, diagnosis, and treatment of urolithiasis in chelonians.

Design: Retrospective case series.

Animals: 40 client-owned turtles and tortoises with urolithiasis.

Mineral composition of urinary calculi from potbellied pigs with urolithiasis: 50 cases (1982-2012).

Objective: To determine the mineral composition and anatomic location of urinary calculi and to investigate sex and reproductive status as predisposing factors for development of urolithiasis in potbellied pigs.

Design: Retrospective case series

Samples: Urinary calculi from 50 purebred and crossbred potbellied pigs.

Procedures: Laboratory records for urinary calculi of potbellied pigs submitted to the University of California-Davis Stone Laboratory from 1982 through 2012 were reviewed.

Evaluation of culture techniques and bacterial cultures from uroliths.

The association between urolithiasis and growth of bacteria in the urine or urolith has not been recently evaluated in the past 15 years, and the effects of antimicrobial administration on urolith cultures have not been reported. As well, laboratory techniques for urolith cultures have not been critically evaluated. The objectives of the current study were to 1) report bacterial isolates from uroliths and their association with signalment, urolith composition, antimicrobial use, and urine cultures and 2) evaluate laboratory techniques for urolith cultures.

Feline urate urolithiasis: a retrospective study of 159 cases.

The objective of the study was to characterize the signalment, clinicopathologic data, and diagnostic imaging of cats with urate urolithiasis, as well as the salts of uric acid present in the uroliths. A retrospective analysis of feline urate uroliths submitted to the GV Ling Urinary Stone Analysis Laboratory between 2000 and 2008 was included. From these data, records were assimilated from referring veterinarians (143); furthermore, all recorded cases from within the William R Pritchard Veterinary Medical Teaching Hospital (16) were included.

Evaluation of trends in urolith composition and characteristics of dogs with urolithiasis: 25,499 cases (1985-2006).

Objective: To evaluate trends in urolith composition and urolithiasis in dogs during the past 21 years.

Design: Retrospective case series.

Sample Population: 25,499 uroliths and the dogs from which they were obtained.

Composition and characteristics of urinary calculi from guinea pigs.

Objective: To determine the mineral composition of calculi, anatomic locations of the calculi, and findings of urinalysis and bacteriologic culture of urine and calculi in guinea pigs with urolithiasis.

Design: Cross-sectional study.

Animals: 127 guinea pigs.

Evaluation of trends in urolith composition in cats: 5,230 cases (1985-2004).

Objective: To determine trends in urolith composition in cats.

Design: Retrospective case series.

Sample Population: 5,230 uroliths.

Dried solidified blood calculi in the urinary tract of cats.

We have noted an increased number of calculi submitted to the Gerald V. Ling Urinary Stone Analysis Laboratory, University of California, Davis, that do not contain crystalline material but appear to be composed of dried solidified blood (DSB). Canine and feline laboratory records from 1986-2003 were reviewed for samples composed of >99% DSB.

Changes in proportion of canine urinary calculi composed of calcium oxalate or struvite in specimens analyzed from 1981 through 2001.

The objective of this report was to characterize 20-year changes in proportion of calcium oxalate (CaOx) calculi and struvite calculi in dogs, and associations with breed, age, and sex. In this retrospective study, results of analysis of urinary calculi from dogs were reviewed for specimens received between July 1, 1981, and December 31, 2001. Breed, sex, age, year of submission of the specimen, and mineral type(s) were analyzed statistically.
