Abstract

Detrusor underactivity (DU) is still largely under researched and can only be diagnosed by invasive pressure flow studies (PFS). Theoretically, the flow shape of DU is different from bladder outlet obstruction (BOO), but in practice PFS is the only gold standard for diagnosing DU. It is suggested that detrusor muscle contraction and abdominal squeezing act in total different frequencies, 0.1Hz and 1Hz respectively, which could be an indicator for differentiating DU and BOO. However, this hypothesis has not been quantitatively validated. Therefore, continuing last year’s research, we have conducted a novel study on validating frequencies of abdominal and detrusor muscle activity as reflected in urine flow, and propose a potential indicator for diagnosing DU.
