Cleft Bladder

Anatomy of the urinary tract

The kidneys have a great ability to form urine, which, however, lasts no more than 21 minutes. Therefore, removing the kidney during this period of time performs the main part of the excretory function. Impaired flow of urine from the kidneys contributes to the development of dehydration and hypertension. When urine enters the pulmonary and systemic circulation after the separation of the kidney, its excretory function worsens.

The blood supply to the bladder is carried out by the iliac branches of the internal iliac arteries, as well as individual branches of the vesical arteries. The urine produced in the bladder is partially filtered and additionally reabsorbed. The largest amount of fluid is absorbed from the upper parts of the bladder, which determines the development of cystorectal reflux. 51% of the resulting concentrate is absorbed into the blood, the remaining doses are absorbed into the tissue of the lower bladder. Inflammatory processes in the lower parts of the bladder contribute to the appearance of erosions and ulcers. **Functionally, most of the tissue of the urinary organs is no longer part of the paired organ, so their function in terms of urine formation is reduced.** This is facilitated by inflammation, nephrosclerosis, sclerosis, congenital structural pathologies, injuries and other pathological processes. All this distinguishes the anatomy of the urinary tract from functionally healthy organs.
