Distribution of the arterial supply to the lower urinary tract in the domestic tom-cat (Felis catus)

Abstract

This study was aimed at determining the arterial supply and gross vascular architecture of the urinary bladder in the male cat. For this purpose, the urinary bladders of 10 cats were evaluated. Organ vascularization was investigated using the latex injection technique. The feline urinary bladder was found to be supplied by the prostatic artery, which stemmed from the internal pudendal artery and the umbilical artery that originated from the internal iliac artery. The umbilical artery extended caudally to form the cranial vesical artery, which was later distributed into the corpus and apex of the urinary bladder. The feline prostatic artery divided into the artery of the deferent duct and a slim branch, which supplied the prostate gland. The artery of the deferent duct gave off a caudal vesical artery which gave off slim branches to the preprostatic urethra. On the surfaces of the urinary bladders examined, the cranial and caudal vesical arteries followed varying courses, which reflected individual variations. In all samples, the blood vessels generally divided into two or three branches on the surface of the urinary bladder, whilst in only one sample, the caudal vesical artery was observed to be of the ladder type. Moreover, the cranial and caudal vesical arteries anastomosed with each other on the surface of the urinary bladder. This study constitutes a model for comparison with other species and provides morphological contributions to anatomy training and surgical interventions since there is a lack of literature on species-specific vascular morphology in the field of veterinary urology in contrast to the abundance of studies on humans and rodents.

Anatomical and Morphometric Variations in the Arterial System of the Domestic Cat

“…Examples of this kind of works are those of Silva et al. () on the inferior mesenteric artery and Erdogan () on the arterial supply of the urinary bladder. Understanding and documenting such anatomical details are critical for both clinical diagnosis and prognosis, as well as for comparative and experimental purposes.…”

“…Variations in several structures of the cat's gross and micro anatomy are mentioned in the literature (Harrison, ; Booth and Chiasson, ; Ghoshal and Magilton, ; Fishbeck and Sebastiani, ), and some of them have been studied in detail (Gilbert, ; Ojima et al., ; Ojima, ; Sturgess et al., ; Eken et al., ; Tomo et al., ; Silva et al., ; Erdogan, ). Considering the importance of cats as model organisms for both teaching and research purposes, understanding and documenting these anatomical variations are therefore relevant.…”

Vascularidad Arterial Extraglandular de la Próstata del Perro

“…En la rata, el suministro de sangre a la próstata proviene de la A. vesical que se origina de la A. ilíaca interna (McVary et al, 1994), Finalmente en el gato la A. prostática se deriva de la A. pudenda interna, y desde ésta surgen las As. vesicales craneal y caudal que irrigan al conducto deferente, la uretra y la prós-tata (Erdogan, 2011).…”

“…There are studies on the male genitalia of Carnivora species (e.g. dog, cat, badger and hoary fox) (Erdoğan 2011, Karan et al 2010, Mehanna et al 2018, Saadon 2016), but there are limited studies on the male genitalia of the wild red fox in the literature. Most assisted reproductive technology development studies are used as models of pet dogs and farm foxes from the Canidae family.…”
