The treatment of men with a sudden painful inability to urinate varies among countries, according to a large study across a wide range of health care systems in France, Latin America, Asia, Algeria, and the Middle East (Fitzpatrick JM et al. BJUI. 10.1111/j.1464-410X.2011.10430.x [published online November 28, 2011]).
The condition, acute urinary retention, is a severe complication associated with benign prostatic hyperplasia (BPH). A cross-sectional survey of 6074 men treated for this urologic emergency showed that most men received urethral catheterization followed by further treatment without a catheter (TWOC). In most cases, the success of TWOC is almost doubled if an α1-blocker is administered before catheter removal.
