本文研究了黄体酮对犬输尿管腔内压及平滑肌蠕动的影响。实验结果表明,肌肉注射黄体酮后输尿管腔内压变化范围明显增大,平滑肌蠕动波频率显著增加,尿量增加约1.5倍。黄体酮对输尿管活动的影响可能是临床使用黄体酮排出输尿管结石及缓解输尿管结石疼痛的作用机制。 In this paper, the effect of progesterone on canine ureter pressure and smooth muscle peristalsis in dogs was studied. Experimental results show that intramuscular injection of progesterone ureteral lumen pressure range was significantly increased, the frequency of smooth muscle peristalsis significantly increased urine output increased by about 1.5 times. The effect of progesterone on ureteral activity may be the mechanism of clinical use of progesterone to expel ureteral stones and relieve the pain of ureteral stones.
