General Surgery · Urology: urinary retention
Sample itemA man with painful inability to pass urine and a palpable suprapubic bladder requires what immediate intervention?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Bladder catheterisation
Acute urinary retention requires prompt decompression, usually with urethral catheterisation, while the cause is investigated. Suprapubic access may be needed if urethral passage fails.
Option by option
A. Bladder catheterisation (correct)
Correct. Catheter drainage relieves obstruction and pain.
B. Fluid restriction only
Restriction does not decompress the bladder.
C. Colonoscopy
Colonoscopy is unrelated.
D. High-dose diuretic
Diuretics increase urine production against obstruction.
