Spinning top urethra and voiding dysfunction in children
Voiding dysfunction is a common clinic complaint during childhood, frequently associated with urinary tract infection, vesicoureteric reflux and chronic constipation.
The aim of the study is to evaluate the existence of an association between the symptoms of voiding dysfunction and the cystoureterogram aspect of spinning top urethra (STU).
Material and method. The study was performed during January 2005 and December 2009 in the IIIrd Pediatric Clinic, Cluj-Napoca. The study included 105 patients with symptomatic voiding dysfunction. The patients were divided in two groups, according to the presents or absence of STU. They were investigated clinically as well as through imaging techniques by means of renourinary ultrasound and voiding cystourethrography.
Results. STU was present in 57.1% of the patients, more frequent in females. Urgency (82.5%) and urinary incontinence (75.3%) were statistically significant associated with STU. In the patients with voiding dysfunction and STU, recurrent urinary tract infection is independently associated with STU.
In conclusion, the cystourethrography aspect of STU is more frequent in females and statistically significant associated with voiding dysfunction symptoms and with recurrent urinary tract infection.
