**Core Concept**
Benign prostatic hyperplasia (BPH) is a common condition in aging men characterized by the enlargement of the prostate gland, leading to obstructive urinary symptoms. Surgical indications for BPH typically involve severe symptoms, complications, or failure of medical management.

**Why the Correct Answer is Right**
Surgical options for BPH include transurethral resection of the prostate (TURP), open prostatectomy, and minimally invasive procedures like laser therapy. These interventions aim to alleviate obstructive symptoms by reducing prostate size or removing obstructive tissue. Surgical indications usually include acute urinary retention, recurrent UTIs, bladder stones, or a post-void residual volume (PVR) greater than 300 mL.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because urinary frequency is a common symptom of BPH, but it is not an absolute indication for surgery. Medical management with alpha-blockers or 5-alpha-reductase inhibitors is often the preferred initial approach.
**Option B:** Incorrect because a prostate size greater than 80 grams is not an absolute indication for surgery. The decision to operate depends on the severity of symptoms and the presence of complications.
**Option C:** Incorrect because recurrent hematuria is not a direct indication for surgery in BPH. Other causes of hematuria should be ruled out before considering surgical intervention.

**Clinical Pearl / High-Yield Fact**
In patients with BPH, a prostate-specific antigen (PSA) level greater than 10 ng/mL is associated with an increased risk of prostate cancer. This highlights the importance of ruling out malignancy before proceeding with surgery for BPH.
