The effect of voiding position on uroflowmetry findings of patients with Benign Prostatic Hyperlasia (BPH) in urology clinic, Hospital Tengku Ampuan Afzan (HTAA), Kuantan, Pahang

Abstract

Benign Prostatic Hyperplasia (BPH) is a common urology disorder presenting to urology outpatient department. It is considered important disease and burden is on the rise in Malaysia because population’s life expectancy increase as BPH is most common in elderly population. Uroflowmetry is a objective evaluation tools of BPH and their effective treatments are limited to medical and surgical therapies. Our aim of this research is to evaluate any effect of changing voiding positions in uroflowmetry findings in patients with BPH. The study positions include standing, sitting and squatting. This is a cross section observational study of BPH patients attending to Urology Clinic HTAA from March 2015 to December 2015. Uroflowmetry in standing, sitting and squatting positions was done in those fulfilling the study criteria. The maximum flow rate, average flow rate, voiding volume, total voiding time and post-voiding residual volume were measured and recorded. The results were then analysed using IBM SPSS Statistic version 23. Descriptive statistic and data analysis was done using ANOVA. Other factors such as normal voiding habit, number of medication, size of prostate, severity of BPH and intravesical prostatic protrusion were also studied for analysed for any significance., No significant difference seen in most parameters studied, however there was statistically improvement in post voiding residual volume in selected patients in squatting positions. The best Qmax was seen when patients performed uroflometry in their preferred normal voiding positions but they were no significant. In conclusion, voiding in sitting or squatting positions is not inferior to standard standing position. Moreover, some improvement was seen in some parameters in selected patients hence might be used as part of behavioural treatment in patients with BPH.
