OBJECTIVE • To assess the association between a history of acute urinary retention (AUR) and complications after transurethral resection of prostate (TURP). PATIENTS AND METHODS • We conducted a retrospective, national, population-based study using Taiwan's National Health Insurance Research Database. • We included men > 50 years old, diagnosed with benign prostatic hyperplasia (BPH) and divided these into two groups: an AUR + group-those with AUR who underwent TURP between 2002 and 2004; and an AUR-group-those without AUR who underwent TURP between those dates. • Prostate cancer, Parkinsonism and multiple sclerosis were exclusion criteria. • Postoperative complications, e.g. re-catheterization, haematuria or urinary tract infection (UTI), were compared using crude odds ratios (ORs), 95% confidence intervals (CIs), and Student's t-test. • A chi-squared test was used for potential confounding factors: preoperative UTI and anticoagulant use. • Univariate and multivariate analysis on medical expenses were conducted. RESULTS • The AUR + group contained 3305 men; the AUR-group contained 1062. • Re-catheterization (13.8%), septicaemia (1.1%) and shock (0.3%) were found only in the AUR + group. • The AUR + group had more UTIs (18.9% vs. 15.6%, OR: 1.26, 95% CI: 1.05-1.52), more lower urinary tract symptoms (22.8% vs. 16.9%, OR: 1.45, 95% CI: 1.21-1.73), fewer blood transfusions (3.2% vs. 1.5%, OR: 2.19, 95% CI: 1.29-3.72) and higher medical expenses. • There were no significant differences in haematuria, lower urinary tract stricture, or re-surgical intervention of the prostate and second-line antibiotic use. CONCLUSION • Patients in Taiwan with BPH with AUR who were treated by TURP were associated with a higher risk of complications, longer hospital stay and more comorbidities than those without AUR and a preoperative warning is warranted for these patients.
