Abstract:In this paper, we observed the structure of the urinary organ in Paramesotriton caudopunctatus using histological and morphological methods. The results showed that the urinary organ of Paramesotriton caudopunctatus was comprised of kidney, ureter and bladder. The kidney was substantive and primarily composed of renal corpuscles and tubular; Renal parenchyma region was delimited with a small number of renal corpuscles, and the tubular was divided into cervical, proximal tubule, intermediate segment, and distal convoluted tubule. Among of which, no reproduction related lymphoid tissue or structure was observed. Ureter was composed of simple cuboidal epithelial and gradually transited to pseudostratified cuboidal epithelium. Bladder wall was composed of 2~3 transitional epithelium cells.
