A Prospective Study of Factors Predicting Outcome of Trial of Void without Catheter in Patients with Acute Urinary Retention Secondary to Benign Prostatic Hyperplasia

Description

Abstract (English)

Abstract
Aim: This study was conducted with the objective to evaluate the parameters that can predict
the success or failure of trial of voiding without catheter (TWOC) for acute urinary retention
(AUR) due to benign prostatic hyperplasia (BPH).
Methods: A prospective study including 100 patients who were hospitalized for BPHassociated AUR was conducted at the Department of Genito-Urinary Surgery, Sri
Venkateswara Institute of Medical Sciences, for 1 year to include male patients who were
hospitalized for BPH-associated AUR. Out of total 100 patients enrolled in our study, 65
(65%) belonged to successful group while remaining 35 (35%) to failed group.
Results: Majority of the patients belonged to the age group 61-80 years in the study. Majority
of the patients belonged to the age group 61-80 years in the study. Total of 78% of patients in
our study accepted having prior LUTS. Duration of symptoms was shorter in successful
group and ranged from no prior LUTS to 18 months when compared to no prior LUTS to 20
months in failed group. Majority of the patients belonged to the age group 61-80 years in the
study. Total of 78% of patients in our study accepted having prior LUTS. Duration of
symptoms was shorter in successful group and ranged from no prior LUTS to 18 months
when compared to no prior LUTS to 20 months in failed group. 45% had IPSS <15 and 53%
had IPSS 15-30. PV was lesser in the successful group, it was not found to be statistically
significant. We had 18 patients (18%) with grade I, 54 (54%) with grade II and 28 (28%)
with grade III IPP.
Conclusion: Severe lower urinary tract symptoms, prostatic pain during DRE, large urine
volume after catheterization, and high blood urea are the predictive factors for TWOC failure
in AUR due to BPH.
