Predicts the Successfulness of a Trial Voiding Without Catheter (TWOC) Through Urine Retention Volume, Detrusor Wall Thickness (DWT) and Intravesical Protrusion of Prostate (IPP) on Acute Urinary Retention (AUR) Patients Due to Benign Prostatic Hyperplasia (BPH)

Abstract

This study aimedwas to identify the successfulness of Trial Voiding without Catheter (TWOC) on acute urinary retention (AUR) patients due to Benign Prostatic Hyperplasia (BPH), based on urine retention volume, Detrusor Wall Thickness (DWT) and Intravesical Protrusion of Prostate (IPP). The 24 patients over 50 years old underwent catheter per urethra and recorded urine volume at retention. Transabdominal ultrasound was performed several days later to evaluate the thickness of the Detrusor Wall Thickness (DWT) and intravesical protrusion (IPP), and detrusor IPP is classified as free de 1 (0- 10 mm). Trial voiding without catheter (TWOC) was carried out on day 5 and was considered successful if the patient was able to spontaneously micturition during first 6 hours, post voided residual volume (PVR) 10 ml/second. Data will be analyzed by simple and multiple logistic regression test with significance level (α = 0.05). The result demonstrate the detrusor muscle thickness examination and IPP degree can be used to predict TWOC success, while urine retention volume does not affect the success of TWOC.
