Role of spinning top urethra in dysfunctional voiding.

AbstractObjective. The role of spinning top urethra (STU) in children with dysfunctional voiding was evaluated retrospectively. Material and methods. From 1995 to 2002, the records of 154 children with dysfunctional voiding were reviewed retrospectively. Of the children 110 (71%) were girls and 44 (29%) were boys (mean age 8 years, range 4–14). All children were neurologically normal and no exhibited physical signs of occult spinal dysraphism. Patients were divided into two groups according to their width of proximal urethra: group I had STU and the group II had normal urethral width. The groups were compared with each other for gender, voiding symptoms, urinary tract infection (UTI), vesicoureteral reflux (VUR) and urodynamic observations. Results. There were 84 children (mean age 8.3 ± 2.2 years, range 4–14) in group I and 70 (mean age 8.0 ± 2.1 years, range 4–14) in group II; no significant age difference was found between the two groups (p = 0.4674). Group I consisted of 66 (71%) girls and 18 (29%) bo...
