Final answer:
Cystography is a surgical procedure involving the suturing of the urinary bladder, which stores urine from the kidneys and expels it via the urethra.
Step-by-step explanation:
Cystorrhaphy is a surgical procedure that involves the suturing of the urinary bladder. This is often necessary after the bladder has been damaged or when there are defects that need repair. The bladder's primary function is to collect and store urine from the kidneys, which is then expelled through the urethra. The ureters are tubes that transport urine from the kidneys to the bladder, while the urethra serves as the conduit for urine to exit the body. The anatomy is slightly different between males and females, particularly in relation to the proximity of the uterus in females and the prostate in males. An important aspect of bladder function is the prevention of urine reflux back into the ureters, which is achieved through an oblique entry of the ureters into the bladder wall, functioning as a physiological sphincter. This design reduces the risk of urinary tract infections and vesicoureteral reflux, especially in children.
