Vesicoureteral reflux caused by manual compression of the urinary bladder performed to obtain urine samples was evaluated by contrast radiography in 10 sedated, clinically normal male and female dogs and in 10 sedated, clinically normal male and female cats. Vesicoureteral reflux occurred in 50% of the dogs and in 40% of the cats. Application of digital pressure to the urinary bladder for a prolonged period to initiate urine voiding was associated with a greater occurrence of reflux than was application of digital pressure for a transient period. Contrast material refluxed into the prostate gland of 3 of 6 male dogs.
通过膀胱造影术对10只镇静状态下临床正常的雄性和雌性犬以及10只镇静状态下临床正常的雄性和雌性猫进行评估，以确定为获取尿液样本而手动按压膀胱所导致的膀胱输尿管反流情况。50%的犬和40%的猫出现了膀胱输尿管反流。与短暂按压膀胱相比，长时间按压膀胱以促使排尿与更高的反流发生率相关。6只雄性犬中有3只的造影剂反流至前列腺。
