title: Technique for the collection of clear urine from the Nile crocodile (Crocodylus niloticus).
abstract: Urine samples can be a very useful diagnostic tool for the evaluation of animal health. In this  article, a simple technique to collect urine from the Nile crocodile (Crocodylus niloticus) was described, based on a similar unpublished technique developed for the American alligator  (Alligator mississippiensis) using a canine urinary catheter. With this technique, it was possible to collect relatively clean urine samples from Nile crocodiles of different sizes using canine urinary catheters or small diameter stomach tubes. Based on the gross anatomical features  of the cloaca of the Nile crocodile, it was confirmed that urine accumulates in a chamber  consisting of the urodeum and coprodeum. Faecal material is stored temporarily in the very  short rectum, which is separated from the urinary chamber by the rectocoprodeal sphincter.
