To the Editor:

I am responding to the AdVanceTM surgical technique paper that was recently published (1). The technique was first described by Rehder & Gozzi and the early results recently published (2). We want to draw attention to a few points of technique that seem very important built on our experience. The authors have performed more than 80 cases of AdVanceTM since February 2006 in a wide range of patients.

The positioning of the patient is critical, as it should not be in extended dorsal lithotomy. Placing and tensioning the sling in this position might cause it to be loose once the legs are back in the supine position. This operative technique is based on providing dorsal support to the sphincteric urethra, which is not given when the sling is loose. The dissection on the urethral bulb is such as to mobilize it, and it is not continued for 4 cm beyond the perineal body as is stated in the article. This means that the bulb should be mobilized until a proximal movement of the proximal bulb becomes possible. When fixing the central portion of the mesh to the mobilized bulb, the distal sutures are most important, necessitating up to three sutures with a 2–0 resorbable suture. The idea is to proximally move and rotate the dorsal surface of the proximal bulb proximally utilizing a broad surface on the bulb. By doing this, the prolapsed dorsal surface of the sphincteric urethra is indirectly supported without causing direct compression on the urethral lumen. A cystourethroscopy during the procedure is not necessary, as the level of dissection and operation is below the pelvic floor and urethra. However, it is of critical importance to make the diagnosis preoperatively, to be able to determine the correct operative indication.

During examination of the stress incontinent patient, the following findings are helpful. The urethroscopy should be carried out in neutral dorsal lithotomy under local anesthesia of the urethra (lidocain gel). With gentle pressure of the pointed index finger directly to the midperineum well dorsal of the level of the membranous urethra the dorsal surface of the proximal bulb should be proximally displaced. A concentric coaptation (occlusion) of the urethral lumen should be appreciated indicating towards possible success with the AdVanceTM sling. When this concentric coaptation cannot be obtained because of large sector defects to the sphincter or severe fibrosis limiting urethral mobility, then this patient should rather be indicated for a compressive device.

Postoperative care should include instruction to limit physical activity especially leg spreading, as this may loosen the sling leading to urinary incontinence again. The AdVanceTM sling is the only product on the market focusing on restoring normal anatomy in male stress urinary incontinence (SUI). In October 2005 Gozzi & Rehder were the first to report on the possibility that urethral prolapse and dorsal sphincteric urethral descent may play a role in male SUI, and restoring this prolapse leads to the restoration of continence (Abstract at the SIU Meeting on Prostatic Disease: Recent Advances and New Technologies. Bariloche, Patagonia, Argentina).
