The present study was undertaken to investigate the effect of the presence of solutions of different osmolality (hypertonic 3%, 4% and 5% hypotonic 0.1%, 0.2% and 0.3% in the urinary bladder on renal urine formation. The study was conducted on 36 dogs of either sex. 100 ml normal saline was used for distending the bladder. Various hypertonic and hypotonic solutions were infused inside the bladder and rate of urine formation was recorded. Presence of hypertonic fluid increased the rate of urine formation and hypotonic fluid decreased it.
本研究旨在探讨膀胱内不同渗透压溶液（高渗3%、4%和5%，低渗0.1%、0.2%和0.3%）对肾尿生成的影响。研究选取了36只雌雄不限的犬。用100毫升生理盐水充盈膀胱。向膀胱内注入各种高渗和低渗溶液，并记录尿生成速率。高渗液的存在增加了尿生成速率，而低渗液则降低了尿生成速率。
