Wide Bladder Neck Syndrome in Children: A Review

Incompetent urethral sphincter in a girl with a unilateral single ectopic ureter

A rare case of an incompetent urethral sphincter associated with a unilateral single ectopic ureter is reported. Urinary incontinence persisted even after removal of a dysplastic kidney draining into the vagina. No neurological defect was found. Manual compression of the bladder elicited urine leakage from the urethra, and the urethral closure pressure was markedly low. Cystometry and voiding cystourethrography were normal. Continence was restored completely by a urethral sling operation.

Review of fundamental urodynamics in children

During the past three years, 190 children were seen with varied and mostly complicated urodynamic problems. Over 300 studies were performed. This experience prompted a reappraisal of fundamental urodynamic concepts pertinent to pediatric bladder disorders.
