Testudinidae In addition to local disease evaluation,1 cloacoscopy may be used for sexing hatchling chelonians and for the study of systemic disease by use of the transparency of the urinary and the accessory bladder wall.2,3 The aim of this multi-structural study is to compare cystoscopy and endoscopy of accessory bladders in chelonians. Cystoscopies were performed on tortoises (Testudo spp.) and turtles (Emys orbicularis, Trachemys spp., Graptemys spp., Pseudemys spp., Pelodiscus sinensis). Coelomic organs were subsequently evaluated from the accessory bladders on turtles. Cystoscopy was performed by use of a 2.7-mm, 30° viewing rigid endoscope inserted through the cloaca and directed toward the urethral opening. Warm (30°C) lactated Ringer’s solution was infused to allow distension of the urethral opening. Once the access to the urinary bladder was gained, the endoscope was directed dorsolaterally until visualization of both gonads was achieved. Following visualization of the gonads the other coelomic organs were inspected. The smallest chelonians in which cystoscopy was successfully performed weighed 23.4 grams. Testes and kidneys were quickly visualized by use of the accessory bladder approach. This could be considered when endoscopy is employed to evaluate adult turtles in which secondary sexual characters are not well defined. Our study confirmed that interposition of the urinary and accessory bladder wall between the endoscope and the coelomic cavity did not preclude the visualization of coelomic organs in any of the examined chelonians, with the exception of few old individuals.
