The purpose of this study was to evaluate and compare positive cystography techniques at 5%, 10%, and 20%, as well as three different double-contrast protocols for detecting radiolucent uroliths with a diameter of less than 3.0 mm in dogs. Six cadavers were used, one was selected at random to...

A 10-year-old intact male Shih Tzu dog presented with hematuria. Double-contrast cystography revealed a polypoid filling defect at the apex of the urinary bladder. Ultrasonography revealed a heterogeneously hypoechoic intramural mass with minimal vascular flow beneath the submucosal layer. After...

Objective - To compare accuracy of estimates of cystolith size obtained by means of plain radiography, double-contrast cystography, ultrasonography, and computed tomography. Sample Population - 30 canine cystoliths ranging from 1 to 11 mm in diameter with various mineral compositions. Procedures -...

Background: Idiopathic renal hematuria (IRH) generally occurs in healthy large-breed dogs that are <2-years-old. It is characterized by recurrent bleeding from the kidneys of unidentified cause. The final diagnosis is reached through the exclusion of primary urinary system and systemic causes of hematuria along with the direct visualization by cystoscopy of hematic urine jets at the ureteral orifice. Case Description: An 8-year-old female neutered Whippet was presented for investigation of a 4-week history of chronic intermittent macroscopic hematuria. Physical examination, systolic blood pressure, extensive laboratory workup (including coagulation profile and platelet count), urine culture, thoracic and abdominal radiographs, pneumocystogram, and double-contrast cystography were all unremarkable. B-mode ultrasound showed no abnormalities apart from a moderate amount of suspended echogenic amorphous material visible within the urinary bladder...

Three series of 24 radiographs were taken. Six healthy adult male dogs weighing 7-16 kg were deprived of food for 24 h and 2 warm water enemas were given before the radiographs were taken. Dogs were anaesthetized with sodium thiopental and contrast medium was introduced using a urethral catheter....

The research involved 2 databases aimed at developing an algorithm integrating epidemiologic information and radiographic characteristics into an equation-based approach to render a reasonably accurate prediction of canine urocystolith mineral composition that would facilitate urocystolith...

A mass lesion was created in the urinary bladder of a canine cadaver to allow evaluation of the effect of patient positioning on the appearance of a mass during double contrast cystography. The mass appeared as a filling defect only on those views where positive contrast medium surrounded the mass. ...

Six cats and eight dogs were studied. Cystitis was easily diagnosed in cats and dogs with the use of the double contrast cystography technique, which was able to demonstrate the local and diffused thickening of the wall of and defects related to filling of the urinary bladder. All animals recovered ...

Urocystoliths of 9 mineral types from 434 canine patients submitted to the University of Minnesota Urolith Bank were imaged in a urinary bladder phantom. Imaging techniques simulated were survey radiography and double contrast cystography. Morphological characteristics visually observed in vitro or ...

This paper reports an special case of TCC located in the distal urethra of a female dog, obtaining the diagnosis through endoscopy, cytology and immunohistochemistry. A nine-year-old, female, neutered Golden Retriever was referred for examination after suffering vaginal bleeding. Vaginal palpation...
