This study demonstrated high PPVs of AUR and BPH in the DNPR during 2011–2017, suggesting that the DNPR is a valid source for epidemiologic research of BPH and AUR.Īlthough administrative healthcare databases, such as the DNPR, are a valuable tool in epidemiological research, continuous validation is essential. We therefore investigated the positive predictive values (PPVs) of BPH and AUR in the DNPR. However, the validity of ICD-10 diagnostic coding of BPH and AUR has not previously been assessed. 7 Since 1994, diagnoses in the DNPR are classified according to the ICD-10. The Danish National Patient Registry (DNPR) contains data on all hospital inpatient admissions since 1977 and emergency room and outpatient clinics since 1995. Many administrative healthcare registries are based on discharge diagnoses coded according to the International Classification of diseases, Tenth revision (ICD-10). National hospital administrative healthcare registries are a potential valuable source of information on BPH and AUR. Previous population-based studies on incidence, risk factors and prognosis of BPH and AUR are sparse, despite an imperative need for more in-depth knowledge on these diagnoses. 6 The reason for this high mortality remains largely unknown. 5 A study from the UK, demonstrated that mortality in men hospitalized with AUR was 2–3 times higher than expected compared with the general population. 4 Before the advent of medical therapy for BPH in the mid-1990’s, AUR was an absolute indication for BPH surgery, and today many men will still undergo surgery after an episode of AUR.

1–3 Acute urinary retention (AUR) is a severe complication to BPH, characterized by a sudden, painful inability to void urine. It is an important cause of lower urinary tract symptoms (LUTS), and 15–25% of men aged 50–64 years report LUTS to a degree that has a substantial negative impact on their quality of life. Benign prostatic hyperplasia (BPH) is common in the aging male population, affecting more than 50% of men above 60 years.
