The purpose of the study - a description of the topography and morphometric
parameters of regional lymph nodes bladder dogs in postnatal ontogenesis.
Material and methods. Studies were performed on autopsy material obtained
from 135 mongrel dogs of both sexes 5 age groups (infants, weaning period, puberty,
physiological maturity and the expression of senile changes) without evidence of
disease of the genitourinary system and infectious diseases. Live weight of adult dogs
was 3- to 6 kg.
The study applied the classical morphological techniques: interstitial injection of
lymphatic channel colored masses, preparation and morphometry.
Results and discussion. The study found that all regional lymph nodes bladder
dogs lie podbryushinnye in the space defined by the bifurcation of the aorta and caudal
vena cava. The frequency of occurrence of the lymph nodes, the number and shape
can vary in the postnatal ontogeny. By the regional lymph nodes constant bladder in
dogs classified lateral and medial iliac and hypogastric lymph nodes. Caudal lumbar
lymph node single, has a predominantly oval and lies at the mouth of the lumbar
arteries, cranial bordering with lumbar lymphatic trunk. In the lymph node, if any fall
afferent lymph vessels, lymph diverting from the dorsal surface of the bladder.For
veterinary Morphologists, clinicians and surgeons of great practical significance have
information about the magnitude of the lymph nodes in postnatal development, so in our
work, we brought morphometry length, width and thickness of all regional lymph nodes
bladder dogs that best reflects their actual size.Morphometric parameters of regional
lymph nodes bladder dogs in postnatal ontogenesis increase with a high degree of
reliability (P <0,001), up until the animals mature. With the onset of the period
expressed senile changes the length, width and thickness of all regional lymph nodes
bladder dogs slightly decreaseWe found that the regional lymph nodes of the bladder
dogs represented by paired medial and lateral iliac and hypogastric lymph nodes, as
well as unpaired caudal lumbar lymph node. Morphometric characteristics of the
regional lymph nodes of the urinary dogs in postnatal development increases until the
animals reach adult-hood. With the onset of a period marked senile changes the length,
width and thick-ness of the regional lymph nodes of the bladder dogs are reduced.
