Purpose: We investigated bladder function on videourodynamic studies in infants with severe primary vesicoureteral reflux (VUR) and analyzed the relationship between VUR and intravesical detrusor pressure during the micturition cycle.
Materials And Methods: From 1999 to 2001, 3 female and 9 male infants with a median age of 9 months with VUR underwent conventional filling videourodynamics at our institution. Four cases were diagnosed by prenatal detection and 8 were diagnosed after symptomatic urinary tract infections.
Purpose: Preoperative prediction of urinary continence in patients with myelodysplasia requiring augmentation cystoplasty is uncertain. To determine reliable factors to predict postoperative urinary continence, we retrospectively analyzed preoperative videourodynamic parameters and urinary continence outcome in a group of patients with myelodysplasia who underwent augmentation ileocystoplasty.
Materials And Methods: Of 75 patients with myelodysplasia with neurogenic bladder dysfunction refractory to conservative management (anticholinergic drugs and clean intermittent catheterization) who underwent augmentation cystoplasty as a single procedure we selected 14 girls and 12 boys without previous vesicostomy drainage and with preoperative and postoperative videourodynamic studies in whom detubularized ileocystoplasty was performed.
Purpose: We retrospectively reviewed 2 series of patients with posterior urethral valves treated initially with valve ablation preceded by bilateral cutaneous ureterostomies or valve ablation alone to evaluate and compare bladder function behavior of each treatment group.
Materials And Methods: From 1970 to 1983, 19 males 22 days to 21 months old with posterior urethral valves were treated with 1 of 2 initial surgical approaches, including upper tract diversion, delayed undiversion and ablation in 11 (group 1), and primary valve ablation only in 8 (group 2). Median patient age at the time of cutaneous urinary diversion and primary valve ablation for groups 1 and 2 was 7 and 9 months, respectively.
Objective: To assess the clinical significance of after-contractions (A-Cs) in children with normal urinary tracts.
Patients And Methods: Urodynamic records obtained in 315 children with urinary infection or enuresis were reviewed retrospectively; 184 were selected for analysis of A-Cs. All patients had normal urinary tracts and none showed signs of an overt neuropathy.
Purpose: We evaluate specific indications, patient selection and complications of the AMS800 artificial sphincter in children and adolescents with sphincteric incontinence.
Materials And Methods: Between 1987 and 1997, 39 males and 10 females with a mean age of 14 years (range 7 to 20) with sphincter deficiency underwent artificial urinary sphincter placement. The underlying etiology of incontinence was myelodysplasia in 38 patients, exstrophy-epispadias complex in 7 and urethral trauma in 4.
