Predictors of successful trial without catheter in acute urinary retention

Objectives:We aim to identify predictors of successful trial without catheter after an episode of acute urinary retention and to evaluate how serum prostate specific antigen (PSA) and C-reactive protein (CRP) levels behave during an acute urinary retention episode and also whether the PSA level is a useful indicator of undetected prostate cancer.Patients and methods:335 patients presented to our institution in acute urinary retention from June 2006 to December 2007. After excluding females, patients with known prostate cancer, clot retention due to haematuria and catheter-related problems, 100 patients were entered into this prospective audit. On admission we documented serum PSA and CRP levels, residual urine volumes, urinary tract infection (UTI), digital rectal examination (DRE) and history of urinary tract surgery. The outcome of subsequent trial without catheter (TWOC) was documented. Where indicated, repeat serum PSA and CRP levels, transrectal ultrasound and prostate biopsies were obtained. Paramet...
