Question

Nocturnal enuresis may be considered normal up to what age?

• A. 3 years
• B. 4 years
• C. 5 years
• D. 6 years

Hint:

Night-time control is expected later than daytime control.

Answer 1

The Correct Option is D

Step 1: Enuresis means involuntary passage of urine beyond the age at which bladder control is normally expected. The expected age differs for daytime and night-time control.

Step 2: Daytime (diurnal) bladder control is usually achieved earlier, by about 4 years of age. Night-time (nocturnal) control develops later.

Step 3: Bed-wetting at night is regarded as a normal stage of development up to about 6 years of age. Only persistent involuntary nocturnal voiding beyond this age is labelled nocturnal enuresis requiring evaluation.

Step 4: Therefore the upper age limit at which nocturnal enuresis is still considered normal is 6 years, making option d correct; the lower ages of 3, 4 and 5 years fall within the normal window and are not the cut-off.
