The role of intra-operative void score during transurethral resection of prostate as a marker of efficacy: a feasibility study

Abstract

Background: To assess the feasibility of a novel intra-operative void scoring technique. To determine if intra-operative void score (VS) could act as a marker for post-operative success following TURP.

Methods: Fifteen patients undergoing TURP were included in this single-centre feasibility study. All patients had indwelling urinary catheters for recurrent retention due to benign prostatic hyperplasia (BPH). In theatre, immediately before- and after TURP, an intra-operative VS was measured and graded 0-5. Primary outcomes were the feasibility of measuring intra-operative VS and its accuracy in predicting surgical outcome.

Results: A combined pre- and post-score with a threshold ≥6 correctly predicted 82% of those who were catheter free (sensitivity) and 100% of those who were not catheter free (specificity) at follow up and the positive predictive value was 100% and negative predictive value 60%.

Conclusion: Intra-operative void score during TURP is simple, reproducible, fast and requires minimal resources. In TURP it may predict successful outcomes by identifying patients who will be catheter free post-operatively as opposed to those who will be catheter dependent despite the procedure.

Keywords: feasibility studies; patient satisfaction; prostatic hyperplasia; transurethral resection of prostate; urinary retention.
