Probably nothing, but perhaps, to be safe you should go and discuss this with a qualified medical practitioner (a doctor).
The bladder.

The complete inability to urinate after surgery, a condition called urinary retention, is considered an emergency if you are no longer in the hospital and you are unable to produce any urine. It is important that you seek treatment immediately, from either your surgeon or an emergency medical facility. If the bladder is not emptied, serious damage can be done to both your bladder and kidneys.
You hold the urine for some time in urinary bladder. Urinary bladder is situated in your pelvic cavity. The formation of the urine is continuous process. You can not go on urinating continuously. That is why the urinary bladder is there.
No. Waste is filtered out of the blood by the kidneys. The liquid waste is then sent to the bladder to be emptied through the urethra.
Urine is stored in the bladder, a hollow organ located in the lower abdomen. The bladder expands as it fills with urine from the kidneys and contracts when it is emptied through the urethra during urination.
As urine accumulates in the bladder, stretch receptors in the bladder wall are activated. These receptors send signals to the brain to indicate that the bladder is full and needs to be emptied. This activates the urge to urinate.
It will decrease by an insignificant amount. (Less than if you emptied your bladder.)
Your bladder stores your urine until you want to eliminate it.
The urine is stored in the urinary bladder before micturition.
Both your bladder and a water balloon hold liquid and can expand to accommodate more fluid. When they are full, they both need to be emptied to prevent bursting.
Urine flows from the kidney to the bladder through a small tube called a ureter. From the bladder it flows outside the body through a small tube called the urethra. This is a closed and sterile system.
