**Core Concept**
The question is testing the understanding of potential complications following Transurethral Resection of the Prostate (TURP), a surgical procedure for treating urinary obstruction caused by an enlarged prostate. The correct answer is related to a specific cause of delayed urinary tract obstructive symptoms after TURP.

**Why the Correct Answer is Right**
The most common cause of delayed urinary tract obstructive symptoms after TURP is **bladder neck contracture (BNC)**. BNC occurs due to fibrosis and scarring at the bladder neck, leading to a narrowing of the urethral lumen. This can result in obstructive symptoms, including urinary retention, difficulty starting urination, and weak urine flow. The development of BNC is thought to be related to the surgical technique used during TURP and the healing process.

**Why Each Wrong Option is Incorrect**
**Option A:** Hemorrhage is a potential complication of TURP, but it typically presents acutely rather than causing delayed obstructive symptoms.
**Option B:** Urinary incontinence is a possible complication of TURP, but it is not typically associated with delayed obstructive symptoms.
**Option C:** Prostatitis is an infection of the prostate gland and can cause obstructive symptoms, but it is not a direct complication of TURP.

**Clinical Pearl / High-Yield Fact**
To prevent BNC, surgeons often use a urethral catheter for an extended period after TURP and may use a urethral stent to maintain patency of the urethra during the healing process.

**Correct Answer: C. Bladder neck contracture.**
