Data are presented on the postnatal growth of the mouse bladder. Both bladder size (measured as surface area) and bladder wet weight increase steadily with age, respectively reaching 2.5 times and 4 times their newborn values by the age of ten weeks. Despite this growth, which may be due principally to non-urothelial components of the bladder, the body weight rises 10-15 fold above the newborn levels. The ratio of bladder weight to the total body weight steadily declines from a peak value in newborn mice to a stable plateau reached at about five weeks of age. The results indicate that a fairly mature bladder exists at birth.
本文给出了小鼠膀胱出生后的生长数据。膀胱大小（以表面积衡量）和膀胱湿重均随年龄稳步增加，到十周龄时分别达到新生时的2.5倍和4倍。尽管这种生长可能主要归因于膀胱的非尿路上皮成分，但体重比新生时增长了10 - 15倍。膀胱重量与总体重的比值从新生小鼠的峰值稳步下降，在约五周龄时达到稳定水平。结果表明，出生时膀胱已相当成熟。
