Correct Answer is D
Explanation
A. "I will always have to wear a pouch.": An ileal conduit requires a pouch to collect continuously draining urine.
B. "I will need to measure my stoma each week.": Stoma size may change initially, so weekly measurements are necessary to ensure a proper pouch fit.
C. "I need to cleanse around the stoma with soap and water.": Gentle cleaning with soap and water helps maintain stoma hygiene and prevent irritation.
D. "I need to catheterize the stoma several times a day.": An ileal conduit is a urinary diversion where urine continuously drains through the stoma into a pouch. Catheterization is not required; this is typically associated with continent urinary diversions.
