Cystoscopy has similar indications in animals, including visualisation and biopsy of mucosa, retrieval or destruction of urinary bladder stones and diagnosis of ectopic ureters. [ 9 ] [ 10 ] [ 11 ] In turtle and tortoises, cystoscopy has additional value as it permits the visualisation of internal organs due to the thin urinary bladder wall. [ 12 ]

Polar body biopsy is the sampling of a polar body of an oocyte. It was first applied clinically in humans in 1987 after extensive animal studies. [ 1 ] A polar body is a small haploid cell that is formed concomitantly as an egg cell during oogenesis , but which generally does not have the ability to be fertilized .
