Summary
This study aimed to explore a noninvasive method for monitoring the deformation (strain) in the detrusor muscle during lower urinary tract symptoms. The researchers used 2-dimensional radio frequency ultrasound imaging to estimate detrusor muscle strain in male patients. They correlated the estimated strain with detrusor pressure and urinary flow rate to understand the relationship. The study included 20 men with lower urinary tract symptoms.
Results showed that ultrasound data acquisition was successful in 13 patients, while it failed in 7 patients due to various factors. In the patients with successful data acquisition, strain in the detrusor muscle positively correlated with detrusor pressure, indicating that the two were related. This correlation was particularly significant in patients with specific bladder contractions.
In conclusion, the study demonstrated that ultrasound imaging can estimate detrusor muscle strain in patients with lower urinary tract symptoms, and this strain correlates positively with detrusor pressure. The results suggest that ultrasound strain imaging may be a valuable tool for real-time monitoring of detrusor muscle activity, especially during the pre-voiding phase.
