Benign Prostatic HyperplasiaNCT06260917
The Effect of Urinating Through the Zipper or by Pulling Down the Trousers on Uroflowmetry Parameters in LUTS
An observational study of Benign Prostatic Hyperplasia and Micturition Disorder, run by Ankara City Hospital Bilkent at 1 site in Turkey (Türkiye).
Trial summary
There are many factors that affect uroflowmetry parameters. One of these is the urination position. Research has mostly focused on standing and sitting urination positions. However, those who prefer the standing position as a habit can urinate by opening the zipper or lowering the trousers. Read more about this study

About this study
Official title: The Effect of Urinating Through The Zipper or By Pulling Down The Trousers on Uroflowmetry Parameters in Patients With LUTS
There are many factors that affect uroflowmetry parameters. One of these is the urination position. Research has mostly focused on standing and sitting urination positions. However, those who prefer the standing position as a habit can urinate by opening the zipper or lowering the trousers. Although the effect of these two applications on uroflowmetry parameters in healthy men has been investigated in only one study, their effect on patients with lower urinary tract symptoms has not been examined.
