- Abstract:
- Objective To explore the clinical value of pelvic floor electromyography (EMG) lag time deduced from noninvasive uroflowmetry with simultaneous pelvic floor EMG in diagnosing children of idiopathic detrusor overactivity(DO).Methods A retrospective analysis was performed for 69 neurologically and anatimically normal children with lower urinary tract symptoms (LUTS).Unknown about the results of pelvic floor EMG lag time in noninvasive uroflowmetry with simultaneous pelvic floor EMG,an urologist made the diagnosis of DO based upon transurethral catheter cystometry.Another urologist unknown about the results of transurethral catheter cystometry made the diagnosis of DO based upon pelvic floor EMG lag time (<2 s) of noninvasive uroflowmetry with pelvic floor EMG.The authors compared the results in the diagnosis of idiopathic DO,tested the consistency and correlation of two diagnostic methods and examined the diagnostic sensitivity and specificity of pelvic floor EMG lag time (ROC curve).Results Pelvic floor EMG lag time in noninvasive uroflowmetry with pelvic floor EMG and measurements of transurethral catheter cystometry had moderate consistency in diagnosing DO(kappa=0.548,P<0.001).The optimal diagnostic standard of pelvic floor EMG lag time was ≤ 1 s,sensitivity was 93.5%,specificity was 63.2% and area under the curve was 0.777.It had a moderate diagnostic value.Conclusion Decreased pelvic floor EMG in noninvasive uroflowmetry with simultaneous pelvic floor EMG may be employed for diagnosing idiopathic DO in children.It is possible to replace invasive urodynamic examination.
