The Role of Urodynamic Study in Evaluating Children with Non Neurogenic Voiding Dysfunction


To evaluate the role of Urodynamic study (UD) in children with non neurogenic voiding dysfunction.A total number of 52 children (age 5 to 12 years) with non neurogenic voiding dysfunction symptoms (frequency, urgency, incontinence, with or without nocturnal enuresis) were evaluated in a period from February 2013 to October 2014 in AL-Sadar Medical City, Najaf. All patients had a noninvasive screening assessment consisting of a detailed voiding history, physical examination, urinalysis, ultrasonography and measurement of post voiding residual urine. All the patients had also undergone Urodynamic (UD), 12 of them the Urodynamic study was done under light general anesthesia (low dose ketamine) or sedative (midozalam) due to patient's un-cooperation. The following urodynamic parameters were measured for maximum bladder capacity (the infused volume immediately before the initiation of micturition), maximum detrusor pressure (Pdet max), bladder compliance and residual urine volume (measured by urethral catheterization). Children with clinical neurological problem were excluded from the study. 41 (78.8%) of 52 children with non neurogenic voiding dysfunction have abnormal Urodynamic findings (detrusor instability, low compliance, reduce bladder capacity).Urodynamic study have a important role in evaluation of children with non neurogenic voiding dysfunction.
