Absorbable versus nonabsorbable graft: outcome of bone anchored male sling for post-radical prostatectomy incontinence.
OBJECTIVE
We determined the outcome of the bone anchored male sling procedure for stress urinary incontinence in men regarding the graft material used.


METHODS
A total of 39 men with post-radical prostatectomy incontinence received a perineal bone anchored male sling. Patients with previous salvage external beam radiotherapy and high serum prostate specific antigen, incontinence due to neurogenic or posttraumatic etiology, or previous benign prostatectomy were excluded. Urodynamic evaluation was performed preoperatively. The number of pads daily used by patients was recorded preoperatively and during postoperative visits. To compress the urethra 2 types of materials were used. Absorbable biomaterials were used in the first 12 patients and nonabsorbable material was used in the following 27.


RESULTS
Mean patient age +/- SD was 67.3 years (range 50 to 79). The mean duration between radical prostatectomy and male sling surgery was 57.9 +/- 40.4 months (range 5 to 135). The procedure was successful in 26 patients (96.2%) in the nonabsorbable group and in 1 (8.3%) in the absorbable group at a mean followup of 18.9 and 28.8 months, respectively.


CONCLUSIONS
The absorbable sling materials that were used for the bone anchored male sling demonstrated disintegration of the material. Autolysis of these absorbable materials removed active compression forces on the urethra after a short period. Nonabsorbable graft is associated with the best outcome following the perineal bone anchored male sling procedure.
