[Periurethral pseudocysts following urethral injections of Zuidex: review of the literature].

Periurethral dextranomer/hyaluronic acid (Zuidex) is a mini-invasive technique for female stress-urinary incontinence and minimal adverse effects were described. Pseudocysts were recently described. Twenty-nine cases only are reported in the literature and the authors illustrate the review with an additional case. Asymptomatic cases, pain and low stream were observed. On clinical examination, a tenderness or visible periurethral deformation need to precise the characteristics with ultrasonography and MRI. Symptomatic cases may benefit from puncture, although the patients must be informed of a potential recurrence of the incontinence.
