First paediatric experience of a new device for "non-endoscopic" periurethral injection in urinary incontinence
Abstract
The results of endoscopic treatment for urinary incontinence (ETUI) depend on the condition of the urethral mucosa and on the length of the urethra. ETUI is quite difficult to perform in female patients, and, in general, in cases of scarred urethral mucosa. A new device (Zuidex, Q-Med, Uppsala, Sweden) has recently been designed for the "non-endoscopic" treatment of urinary stress incontinence in women. Three paediatric cases are described hereunder. Three patients were treated using Zuidex: two patients (two girls aged 8 and 18) on intermittent catheterization for neurogenic bladder, and one 11-year-old girl, with epispadias, who had already undergone bladder neck reconstruction (Young-Deese). Zuidex is a special implacer for dextranomer implants. It consists of four syringes filled with dextranomer, one implacer, and four needles (25 gauges). Once the device is positioned, the four injections are performed. At the end of this procedure, four implants are symmetrically positioned at four points of the urethral wall, increasing the outlet resistance. In the follow-up phase (5-13 months), the increase in the continent period was +56, 50 and 36%; the increase in bladder capacity (leak volume point) was 40, 28 and 27% in the three patients. Although the new device for "non-endoscopic" treatment of urinary incontinence has been designed for women, the size of the implacer virtually allows its use in any paediatric patient who is above the age of six. Our early experience…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
