Epithelium transitionale

Epithelium transitionale est genus inter epithelia ex pluribus stratis compositum, ita epithelium stratificatum nominatur. Invenitur in pars ureteris prima (calyce, immediate post renem) velut in vesica urinaria. In vesica urinaria epithelium transitionale etiam urothelium dicitur. Urothelio facultas inter se movendi est, ita superficiem internam multitudinis urinae intra vesicam accomodari potest.

Epithelium transitionale

Vesicae urinariae epithelium transitionale, etiam urothelium notum est, Conpicue sunt cellularum apicalium superificies rotundae: forma ista insigne epitheliorum ipsorum est.

Epithelio transitionali facultas osteogenesis (formationem ossis) post operationem vesicae urinariae^[1].

Anatomia microscopica

Epithelium transitionale vesicae urinariae (urothelium) compositum est ex stratis tribus ad sex^[2]. Architectura inter strata videtur eadem, tamen differentiatio cellularis ab base ad superficiem auget. Virtus specialis urothelii est facultas sua inter se moviendi ut superficies vesicae internae urinariae commutari potest.

Physiologia

Videtur, ut ureteris epithelio transitionali facultas substantiarum ingerendi ab urina est^[3].

Morbi epithelii transitionalis

Neoplasma

Neoplasmata urothelii imprimis in vesica urinaria exoriuntur (→cancer vesicae), tantum centesimae quinque in ureteribus vel renibus (systemate pelvicalyceali)^[4]. Rara sunt neoplasmata in natis ante quadraginta annos^[5].
