OBJECTIVE To determine the effectiveness of cystotomy for complete removal of urocystoliths and urethroliths in dogs, the types and frequency of diagnostic imaging performed to verify complete urolith removal, the complications that develop as a result of cystotomy, and predictors of each of these variables. DESIGN Retrospective case series. ANIMALS 128 dogs that underwent a cystotomy for r...

Diagnostic imaging is usually required to determine the presence of urolithiasis. Double-contrast cystography is more accurate than survey radiography and approximately as accurate as ultrasonography. Knowledge of the mineral composition of calculi helps direct appropriate management of urolithiasis, and signalment can help predict composition with about 70% accuracy. In cats, about half of cys...

BACKGROUND Laser lithotripsy has been used as an alternative to surgical removal of uroliths. OBJECTIVE To describe the procedure and efficacy of laser lithotripsy for removal of lower urinary tract uroliths in horses. Additionally, the ultrastructure and the differences in mineralogy and microstructure from 1 successful and 1 unsuccessful laser lithotripsy case are described. ANIMALS Six c...

A 14-month-old intact male Syrian hamster was admitted for lethargy and hematuria. A total body radiographic image and abdominal ultrasonography showed the presence of a vesical calculus. During cystotomy, a sterile urine sample was obtained and sent to the diagnostic laboratory along with the urolith for analysis. Urine culture was found negative for bacterial growth, and the urolith was ident...

Initiation and Growth of Uroliths Urolith formation, dissolution, and prevention involve complex physical processes. Major factors include: 1) supersaturation resulting in crystal formation, 2) effects of inhibitors of crystallization and inhibitors of crystal aggregation and growth, 3) crystalloid complexors, 4) effects of promoters of crystal aggregation and growth, and 5) effects of non-crys...

OBJECTIVE To evaluate the effect of dietary supplementation with sodium chloride (NaCl) on urinary calcium excretion, urine calcium concentration, and urinary relative supersaturation (RSS) with calcium oxalate (CaOx). ANIMALS 6 adult female healthy Beagles. PROCEDURE By use of a crossover study design, a canned diet designed to decrease CaOx urolith recurrence with and without supplemental...

pasteurella species are commensal bacteria of the respiratory airways and oronasal cavity of animals. in this study, we report an unusual case of pasteurella dagmatis isolation from dog urine with uroliths. an 11-year-old female dog was admitted to the veterinary hospital of ahvaz university complaining of abdominal pain, hematuria, dysuria and stranguria. in clinical and radiological examinati...

A 35-year-old male patient with a past history of traumatic penile amputation and subsequent penile reconstruction with a radial artery free flap phalloplasty presented to the urology clinic for urinary retention and complaint of a firm penile mass. The patient had been lost to follow-up for 2 years before this presentation. Patient had a suprapubic tube in place from initial surgery, with imag...
