The importance of Bladder Contractility Index in the management of underactive bladder

Aim: To evaluate the importance of BCI in the management of underactive bladder (UB). Material and method: A retrospective study over a period of 3 years and 9 months (January 2013-September 2016) in Mures County Hospital, Clinic of Urology, including 91 patients. Detrusor underactivity was defined by BCI less than 100 using the formula: PdetQmax+5Qmax. Results: The median of Qmax value was 7 ml/s and the median value of Pdet was 14 cm H2O. The median value of BCI was 55 with extremities between 17 and 110. BCI tends to decrease with age and there is a relation between value of BCI and diabetes (p = 0,003) and neurological diseases (p = 0,015). Conclusions: The UB diagnosis represents a real challenge for the urologist, so that, urodynamical findings such as absence of bladder obstruction, post-void residual urine, Qmax, together with BCI value, helps in setting the proper management.
