Structure Organization of Urinary System in the Yellow Spotted Mountain Newts (Salamandridae: Neurergus microspilotus).

This study deals with the histomorphology of the mesonephros in male and female Neurergus microspilotus. The slender and narrow kidneys are positioned in the retro peritoneal position up against the ventral aspect of vertebral column and may extend the length from the esophagus-stomach junction to cloaca. The kidney in both sexes is composed of sexual (anterior) and pelvic (posterior) parts. The duct of sexual kidney is a narrow duct which is lying entering the cloaca, two ureters are joined together and open to the apex of the cloaca. In the male, after entering the sexual kidney, the sperm leave the testis through efferent ducts, then these ducts join together and eventually form
