Question

If a person cannot void his or her bladder voluntarily, a urinary catheter can be used to pass the urine. Unfortunately this may have consequences that impact the homeostatic condition, such as urinary tract infections. What are the internal passages through which a catheter must pass to reach the bladder, and how can they be impacted?

Answer 1

Ans:-structures through which catheter pass are bulbus uretha then spongy urethra then membranous urethra then prostatic urethra then internal urethral spincter then urinary bladder.

it is hold in its place by a inflatable balloon like str which is inflated after the catheter reaches the urinary bladder. So this balloon holds the catheter side the bladder.

The male urethra has three sections:

• The prostatic urethra crosses the prostate gland. ...
• The membranous urethra is a short section that goes through the urethral sphincter. ...
• The spongy or penile urethra goes through the pe*is on its lower side. ...
• The "bulbar" urethra.

Catheterisation can damage the utethra lining , and can cause various side effects like:-

• allergic reaction to the material used in the catheter, such as latex
• bladder stones
• blood in the urine
• injury to the urethra
• kidney damage (with long-term indwelling catheters)
• septicemia, or infection of the urinary tract, kidneys, or blood

• fever
• chills
• headache
• cloudy urine due to pus
• burning of the urethra or genital area
• leaking of urine out of the catheter
• blood in the urine
• foul-smelling urine
• low back pain and achiness
