Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understand the late complication.
After transurethral resection of the prostate, a recognised late complication causing recurrent obstruction is fibrotic scarring leading to stricture or contracture.
Step 2: Identify the commonest site.
Bladder neck contracture (bladder neck stenosis) is the most common cause of obstruction following TURP, arising from scarring at the bladder neck after resection.
Step 3: Distinguish from urethral strictures.
Urethral strictures after TURP also occur, classically at the meatus, navicular fossa, bulbar urethra or membranous urethra due to instrument trauma, but the single most common obstructing lesion specifically attributed to TURP is bladder neck contracture.
Conclusion: Bladder neck is the most common site, matching the printed key.
