Pdf Summary

This study investigated detrusor underactivity (DU) in women with urinary incontinence. The aim was to determine the predictive value of pressure flow analysis in diagnosing ineffective voiding in a large cohort of women. A total of 504 women were included in the study, with an age range of 20-99. Participants had voided more than 100mL and had a post-void residual (PVR) volume of less than 500mL without significant straining. Various contraction parameters were measured, including Pdet, qmax, qmean, qaccel, Wmax, BCI, PIP, and Tq. The study found that these contraction parameters had a high correlation with residual volume and voiding time. Wmax had the highest coefficient, indicating its superior predictive value. The study also noted that obstructed voiding, which can lead to similar signs as DU, was rare in the cohort (<5%). The researchers concluded that detrusor underactivity can be reliably quantified using urodynamic tests and that Wmax analysis is the most effective in predicting PVR and prolonged voiding. This study provides valuable insights into the diagnosis and management of detrusor underactivity in women with urinary incontinence.
