Flowmetry/pelvic floor electromyographic findings in patients with detrusor overactivity

Abstract

ABSTRACTTo evaluate different flowmetry/EMG patterns in patients with proven detrusor overactivity (DO) and compare them with that of a group of patients with lower urinary tract symptoms (LUTS) but without DO.Materials and MethodsWe retrospectively evaluated the records of 100 patients with frequent urinary tract infection or any kind of storage or voiding symptoms that had undergone urodynamic testing: 50 cases with proven DO on cystometry who had a good quality flowmetry/EMG and 50 patients without DO. EMG lag time (the time distance between pelvic floor EMG inactivation and the start of urine flow) and different flow curve pattern were recorded and compared.ResultsThe age and gender distribution were not statistically significant between the two groups. A negative lag time (≤ 0 sec) and an obstructive pattern were the only parameters that were more commonly seen in the DO group. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of a lag times ConclusionsA lag time
