The aim of the study was to validate some of the imaging criteria for voiding dysfunction in children. Material and methods: The study included a number of 55children with voiding dysfunction symptoms. They were investigated clinically as well as through imaging techniques: renourinary ultrasound, voiding cystourethrography and cystometry. Results: The most common symptoms were urgency (87.3%), increased frequency (81.8%), and daytime urinary incontinence (76.3%). Ultrasound scans detected a reduced bladder capacity in 65.5% patients. The voiding cystourethrography detected bladder trabeculations (58.2%) and spinning top urethra (63.6%). Cystometric recordings indicated overactive bladder in 70.9% patients. Reduced bladder capacity detected by ultrasound associated with trabeculated bladder and spinning top urethra detected by voiding cystourethrography in a patient with specific symptoms may suggest an overactive bladder. In conclusion, voiding dysfunction in child can be diagnosed by minimal or non-invasive methods.
