INTRODUCTION - One of the methods to treat post radical prostatectomy stress urinary incontinence is the AdVance™ (American Medical Systems®, Minnetonka, MN, USA) male sling procedure. During this procedure, the somatic innervation of the penis may be at risk for injury. Six AdVance™ procedures were performed in six donated bodies at the Anatomy and Embryology Department of the Leiden University Medical Centre. The pelves were dissected and the shortest distance between the sling and the dorsal nerve of the penis (DNP) was documented.
AIM - The aim of this study was to describe the anatomical relation between the AdVance™ male sling and penile nerves based on the dissection of six adult male pelves.
METHODS - The AdVance™ male sling procedure was conducted in six donated male bodies. After placement, the pelves were dissected and the shortest distance between sling and the DNP was documented.
MAIN OUTCOME AND MEASURES - The main outcome measure was the distance between the AdVance™ male sling and the DNP.
RESULTS - The mean distance of the sling to the DNP was 4.1 mm and was found situated directly next to the nerve (distance 0 mm) in 4 out of 12 (33%) hemipelves. The distance of the sling to the obturator neurovascular bundle was 30 mm or more in all six bodies.
CONCLUSIONS - Damage to the DNP caused by the AdVance™ male sling procedure appears to be an extremely rare complication, which has not been described in current literature. The proximity of the AdVance™ to the DNP could, however, pose a risk that should be taken into consideration by physicians and patients when opting for surgery.
