%X Con el fin de establecer las caracter¨ªsticas morfol¨®gicas de las v¨ªas urinarias del Caiman crocodilus crocodilus, se realiz¨® el estudio morfol¨®gico de las v¨ªas urinarias de nueve babas macho adultas, usando las coloraciones Hematoxilina-Eosina y Tricr¨®mica de Mallory. Se concluye que la presencia de t¨²nica muscular a partir de los t¨²bulos colectores puede relacionarse con la necesidad de movilizar peque as cantidades de orina cargada de uratos precipitados mediante movimientos perist¨¢lticos, lo cual se asociar¨ªa con la necesidad de este reptil de producir vol¨²menes reducidos de orina isosm¨®tica, por lo cual se reduce la p¨¦rdida de l¨ªquido a nivel renal. Posiblemente, esto implica la secreci¨®n de mucinas lubricantes a lo largo de v¨ªas urinarias, como un mecanismo facilitador del transporte de los uratos precipitados. A study was conducted with the purpose of establishing the morphologic characteristics of the urinary pathway of the male spectacled caiman (Caiman crocodilus crocodilus). A total of nine adult caimans were used. Samples of the urinary tract were collected and stained with Hematoxilyn-Eosin and Mallory¡¯s trichromic stains. The results of the present study reveal that the presence of a muscular layer, departing from the collecting tubules, could be associated to the need of mobilizing small amounts of urine loaded with precipitated urates, by means of peristaltic movements, which may be associated with the need of this reptile of producing reduced volumes of isosmotic urine. This would lead to a reduction of fluid loss at a renal level. This possibly implies the secretion of mucines along the urinary tract, as a facilitator mechanism for the transport of precipitated urates.
