A 68-year-old man from Delhi presents with lower urinary tract symptoms (LUTS) including nocturia (×4/night), hesitancy, and weak stream for 6 months. Digital rectal examination reveals a smooth, firm, symmetrically enlarged prostate without nodules. PSA is 2.8 ng/mL (normal <4). Urinalysis is normal. Post-void residual (PVR) is 80 mL. What is the most appropriate next step in management?

Explanation

## Clinical Assessment This patient presents with **benign prostatic hyperplasia (BPH)** with lower urinary tract symptoms (LUTS). The clinical clues are: - Smooth, symmetrically enlarged prostate on DRE (no nodules) - Normal PSA (2.8 ng/mL) - Moderate PVR (80 mL) - No hematuria or systemic symptoms ## Management Algorithm for BPH ```mermaid flowchart TD A[LUTS + Enlarged prostate]:::outcome --> B{PSA elevated?}:::decision B -->|Yes, nodular| C[Biopsy to rule out cancer]:::action B -->|No, smooth, symmetric| D[Assess symptom severity]:::decision D -->|Mild-moderate| E[Medical management: Alpha-blocker ± 5-ARI]:::action D -->|Severe, refractory| F[TURP or laser therapy]:::action E --> G[Review at 6-8 weeks]:::outcome G -->|Improved| H[Continue medical therapy]:::action G -->|Failed| I[Consider TURP]:::action ``` ## Why Medical Management First? **Key Point:** In uncomplicated BPH with moderate LUTS and normal PSA, **medical management is the first-line approach** per AUA/EAU guidelines. **High-Yield:** Alpha-blockers (tamsulosin, doxazosin) provide symptom relief within 1–2 weeks by relaxing smooth muscle in the prostate and bladder neck. 5-alpha reductase inhibitors (finasteride, dutasteride) reduce prostate volume over 6–12 months and are especially useful if: - Prostate volume >30 g on imaging - PSA >1.5 ng/mL (predicts good response) - Recurrent urinary retention or UTI **Clinical Pearl:** PVR of 80 mL is acceptable for conservative management; intervention is typically considered if PVR >100–150 mL with recurrent UTI or retention. ## Why Not the Other Options? | Option | Reason for Rejection | |--------|---------------------| | TURP | Reserved for refractory LUTS after failed medical therapy, or acute retention. Not indicated as first-line in this stable patient. | | Prostate biopsy | Only indicated if PSA is elevated (>4 ng/mL) or DRE shows nodules/asymmetry. Normal PSA and smooth enlargement make cancer unlikely. | | Urodynamic studies + cystoscopy | Invasive investigations reserved for complex cases (failed TURP, neurogenic bladder, post-void dribbling). Not indicated for uncomplicated BPH. | [cite:Harrison 21e Ch 305]
