Determination of the predictive value of IPSS on the outcome of trial of voiding without catheter in BPH patients presenting with acute urinary retention

Abstract

Background: Acute urinary retention is a common urological emergency. This study was to determine the value of storage IPSS, voiding IPSS and total IPSS in predicting the outcome of trial of voiding without catheter in patients with BPH presenting with acute urinary retention.
Methods: This was a prospective observational study that included patients seen at the Accident and Emergency Unit of Jos University Teaching Hospital with acute urinary retention from benign prostatic hyperplasia. Each patient had clinical evaluation, and urethral catheter was passed to relieve the retention, then an International Prostate Symptom Score questionnaire was patient self- administered. The patients were all placed on Tamsulosin 0.4 mg daily for 3 days after which they had trial of voiding without catheter (TWOC). Statistical analysis was done using SPSS(R) version 23 and MedCalc Statistical software version 17.2.
Results: Seventy-six patients with age range 52 - 82 years were enrolled in the study. The means of IPSS storage, IPSS voiding and IPSS total were 9.00, 10.64 and 19.55 respectively. IPSS storage (AUC = 0.768, p < 0.0001), IPSS voiding (AUC = 0.760, p < 0.0001), and IPSS total (AUC = 0.793, p < 0.0001) predicted the outcome of trial without catheter (TWOC) with cut-off marks of 9, 10, and 20 respectively. Conclusion: IPSS storage, IPSS voiding, and IPSS total significantly predicted the outcome of trial without catheter in patients with BPH presenting with acute urinary retention.
