Benign prostatic hypertrophy (BPH) is a non-cancerous enlargement of the prostate gland that obstructs urine flow and can cause various urinary tract issues as men age. Symptoms include dysuria, nocturia, and urinary retention, and diagnosis may involve physical examinations, PSA tests, and imaging techniques like ultrasounds. Treatment options range from medications like alpha-blockers to surgical interventions such as transurethral resection of the prostate (TURP) for severe cases.
