Compression of the brain by the accumulating fluid eventually may cause neurological symptoms such as convulsions, intellectual disability, and epileptic seizures. These signs occur sooner in adults, whose skulls are no longer able to expand to accommodate the increasing fluid volume within.
The signs and symptoms of hydronephrosis depend upon whether the obstruction is acute or chronic, partial or complete, unilateral or bilateral. Hydronephrosis that occurs acutely with sudden onset (as caused by a kidney stone) can cause intense pain in the flank area (between the hips and ribs) known as a renal colic. Historically, this type of ...
Typically, an infant's brain weighs around 400g at birth and triples to 1100-1400g by age 11. At the same time the cranium triples in volume from 500 cm 3 to 1500 cm 3 to accommodate the growing brain. [60] During human evolution, the skull underwent numerous changes to accommodate the growing brain.

Damage to the brain or spinal cord is the most common cause of neurogenic bladder. Damage to the brain can be caused by stroke, brain tumors, multiple sclerosis, Parkinson's disease, multiple system atrophy or other neurodegenerative conditions. [8] Bladder involvement is more likely if the damage is in the area of the pons.
When the brain stops receiving oxygen, the adenosine triphosphate (ATP) stores that act as fuel for the cells quickly get sucked away. Then, it all becomes a bit chaotic. Electrical balances go ...
Ureterovesicular junction obstruction (UVJ obstruction) is an obstruction at the level of the ureter and bladder. It accounts for 20% of cases of hydronephrosis detected in utero. It is also most commonly seen in males and involved both sides of the urinary tract in approximately 25% of cases. [1]
