Pressure-length-diameter relationships of neonatal and adult rabbit ureters were studied in vitro. The increase in diameter, in response to an intraluminal pressure load of 10, 20, and 40 g per cm2, was faster and greater in the neonate than in the adult. Incubation in norepinephrine decreased the diametral deformation of neonatal ureters but had little effect on deformation in the adult ureter. The in vitro neonatal rabbit ureter, thus, appears to be more compliant and more sensitive to norepinephrine than the adult ureter.
对新生兔和成年兔输尿管的压力-长度-直径关系进行了体外研究。腔内压力负荷为每平方厘米10克、20克和40克时，新生兔输尿管直径的增加比成年兔更快、更大。用去甲肾上腺素孵育可减少新生兔输尿管的直径变形，但对成年兔输尿管的变形影响很小。因此，体外培养的新生兔输尿管似乎比成年兔输尿管更顺应性，对去甲肾上腺素更敏感。
