Abstract: | PURPOSE: To evaluate the cause and management of paraurethral abscess developing after injection of a mixture of hyaluronic acid and dextranomer (Zuidex) for treating stress urinary incontinence. PATIENTS AND METHOD: A total of 127 women having undergone midurethral Zuidex injection and 34 women after endoscopically guided Deflux injection into the tissue around the bladder neck were followed up 1 to 24 months after the intervention. At follow-up, the paraurethral tissue was evaluated clinically by gynecologic examination and by introital ultrasound. RESULTS: Thirteen of 127 women (10 %) having undergone midurethral Zuidex injection had a sterile paraurethral abscess that was treated by transvaginal puncture (1 to 3 punctures with removal of 10-60 ml of fluid per patient). No case of postoperative paraurethral abscess formation was demonstrated in the control group treated by Deflux injection into the area around the bladder neck. CONCLUSIONS: Paraurethral abscess must be excluded in the postinterventional follow-up of patients after Zuidex injection. Patients in whom an abscess is demonstrated can be treated by transvaginal puncture. Abscess formation can be avoided by injecting dextranomer/hyaluronic acid into the area around the bladder neck. |
