The urodynamic changes in 10 bitches up to 18 months after they had undergone ovariectomy were investigated. There were significant decreases in the maximum urethral closure pressure, the functional urethral length and the total integrated pressure profile 18 months after spaying, resulting in a caudal shift of the urethral profile, and a deterioration of urethral closure function. Each urethral pressure profile was divided into three equal sections; the mean cranial and middle integrated pressure decreased significantly and consistently over the 18-month observation period whereas the caudal integrated pressure increased.
对10只母犬在卵巢切除术后长达18个月的尿动力学变化进行了研究。绝育18个月后，最大尿道闭合压、功能性尿道长度和总综合压力曲线均显著下降，导致尿道曲线尾端移位，尿道闭合功能恶化。每条尿道压力曲线被分为三个相等的部分；在18个月的观察期内，头段和中段的平均综合压力持续显著下降，而尾段综合压力则升高。
