Three-dimensional Power Doppler Ultrasonographic Evaluation of Induced Cystitis in Dogs

Objectives: The aim of this study was to investigate if three-dimensional power Doppler (3DPD) ultrasound (US) can detect bacterial cystitis in dogs better than two-dimensional (2D) US. Animals: Six mixed breed dogs Procedures: Ten ml of 0.1% alcoholic solution of salicylic acid was entered into the urinary bladder of six male mixed-breed dogs by catheter. Twenty four hours later, culture solution of Proteus mirabilis (103CFU /ml) was inoculated into the urinary bladder. The dogs were examined with complete blood and urine analysis and bacteriological culture on specified days during the infection and the treatment period. The urinary bladders of dogs were assessed by both 3DPD and 2D US techniques. All dogs were treated with therapeutic doses of Ceftriaxone for two weeks, 14 days after the infection. Results: results showed that 3DPD can better define the morphological and vascular characteristics of cystitis; 1 however, the main lesions were identified by both 2D and 3DPD US. Clinical Significance: The data showed that, the indicators of 3DPD can differentiate the disease acuteness and treatment response better than 2D US.
