Purpose: To investigate the incidence of benign prostatic hyperplasia (BPH) in Korea and treatment patterns for 3 years after the diagnosis in a nationwide database. Materials and Methods: We created a cohort of patients diagnosed of BPH between 2007 and 2011 from the Health Insurance Review & Assessment database, a nationwide database of reimbursement. The diagnosis of BPH was defined as having the diagnosis of BPH (N40.0 in International Classification of Diseases, 10th revision) as a primary or secondary diagnosis ≥2 times in 2008. The incidence of BPH in 2008 was calculated. Treatment patterns were determined in 3 months interval and traced for 3 years. The incidence and timing of surgery were also determined. For patients taking medications preoperatively, medication-free rate was calculated. Results: The incidence of BPH was 2,105 per 100,000 men (mean age, 59.7±11.4 years), and increased with age. Surgery was performed for 7,955 patients (2.1%), half of the surgery being performed within the first 6 months. Transurethral resection of the prostate was the most commonly performed surgery. The proportion of treatment increased with age until the 7th decade of life. The patients taking medication for >1 year after the initial diagnosis was 21.4%. On average, 82% of patients became medication-free at postoperative 1 year. For patients taking preoperative anticholinergics, 1 year medication-free rate was 73.3%. Conclusions: The incidence of BPH increased with age. Surgery was performed in 2.1% of patients. More than 4/5 patients discontinued medication after surgery, while patients taking preoperative anticholinergics were less likely to.
