[Paraurethral abscess developing after mid-urethral Zuidex-injection in women with stress urinary incontinence -- management of complications and retrospective comparison with bladder neck located injection technique].
OBJECTIVE
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.


METHODS
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.
