Transurethral Resection Urinary Retention Predictor (TURP) Score: A Novel Perioperative Predictor of Post-Operative Urinary Retention

The study, conducted from 2005 to 2015, retrospectively reviewed 417 patients who underwent Transurethral resection of the prostate (TURP) to identify predictors of postoperative urinary retention. It was found that 72% of these patients attempted a void trial after TURP, with 20% failing to void. Patients who attempted and underwent a void trial had lower odds of having a history of urinary retention (OR 0.18, 95% CI 0.09-0.37; p<0.001) and were more likely to undergo a less extensive resection volume (OR 1.01, 95% CI 1.00-1.02; p=0.01). Those who failed a void trial were more likely to be older (OR 1.04, 95% CI 1.01-1.08; p=0.02), have a history of urinary retention (OR 1.71, 95% CI 0.91-3.23; p=0.1), and be prescribed finasteride preoperatively (OR 2.16, 95% CI 1.13-4.13; p=0.02). These findings could help healthcare providers identify suitable candidates for immediate void trial following TURP.
