Bulking agents: anesthesia techniques.

Bulking therapy for the minimally invasive treatment of stress urinary incontinence (SUI) may be offered to women with urodynamic SUI, wishing to avoid the complications associated with more invasive surgery, on the basis of low operative morbidity and low longterm success rates. These bulking agents may be injected by a retrograde or antegrade technique in the periurethral tissue around the bladder neck and proximal urethra. This therapy is strongly dependent on the anesthetic technique of choice; moreover its application as an outpatient procedure implies the potential for a cost-effective treatment for selected patients with SUI. In the present paper all factors affecting the choice of different types of anesthetic techniques are discussed.
