MORPHOLOGICAL ASPECTS OF THE FEMALE PIG BLADDER NECK AND URETHRA: QUANTITATIVE ANALYSIS USING COMPUTER ASSISTED 3-DIMENSIONAL RECONSTRUCTIONS

摘要: Purpose: To investigate whether the pig is a suitable model for studies of lower urinary tract function and dysfunction, we sought to determine morphology female bladder neck urethra. Computer assisted 3-dimensional (D) reconstructions from step serial histological sections were used visualization spatial relationships between neighboring urethral wall components, quantification these components in along urethra.Materials Methods: Step paraffin urethra 6 pigs, stained with Masson’s trichrome, generate computer 3-D using MacStereology (Ranfurly MicroSystems Ltd., Airdrie, United Kingdom) as software package.Results: The anatomy revealed well defined smooth striated muscle layers that varied location, regional distribution orientation. Circular was maximally developed mid ...
