Urinary obstruction in the lower urinary tract triggers changes to the urinary system to compensate for the obstruction. what is an early change the system makes in its effort to cope with an obstruction?

The early change that the system makes in an effort to cope with an obstruction is that the stretch receptors in the bladder wall become hypersensitive. Urinary tract obstruction is a blockage that inhibits the flow of urine through the urinary tract, including the kidneys, ureters, bladder, and urethra. The blockage mat be partial or complete. In response to the obstruction the urinary system is capable of undergoing adaptive changes or responses to compensate for the obstruction.
