Use of rectus fascia graft for corporeal reconstruction during placement of penile implant.

OBJECTIVES: To report on the technique of using autologous rectus fascia graft for corporeal and tunica reconstruction during placement of an inflatable penile prosthesis. Reconstructing the corpora cavernosa and closing the tunica albuginea over an inflatable penile prosthesis can be challenging when severe fibrosis is encountered. METHODS: Fifteen patients with severe fibrosis of the corpora or tunica were included in this study. Eight patients had severe corporeal fibrosis secondary to an infected or malfunctioned penile prosthesis that had been previously removed, and seven had severe penile curvature secondary to tunical fibrosis with concomitant erectile dysfunction. All patients underwent corporeal or tunica reconstruction using autologous rectus fascia after placement of an inflatable penile prosthesis. Postoperatively, patients were evaluated at 1, 6, 12, and 24 months. Data on patient satisfaction, graft function, and complications were recorded. RESULTS: At a mean follow-up of 18 months (range 12 to 64), augmentation of the tunica or corporeal defect using autologous rectus fascia graft was successful in all patients. The penile prostheses were functioning properly with no evidence of graft infection, erosion, or abdominal wall hematoma. Patients demonstrated good results, with return to sexual intercourse at a mean of 9 weeks postoperatively (range 8 to 10). CONCLUSIONS: Use of an autologous rectus fascia graft for coverage of a tunical or corporeal defect during penile prosthesis placement in patients with corporeal or tunica fibrosis is surgically feasible, safe, and efficacious. Long-term follow-up of this reconstructive technique has demonstrated excellent clinical results with no morbidity related to the rectus fascia graft harvesting.

The male perineal sling: comparison of sling materials.

PURPOSE: Urinary incontinence continues to be a significant problem for patients after radical prostatectomy. The male perineal sling is emerging as a safe and effective treatment option for postprostatectomy stress urinary incontinence. We compare the efficacy of porcine dermal collagen and silicone mesh as the sling material. MATERIALS AND METHODS: Of 36 patients with postprostatectomy stress urinary incontinence a porcine dermal collagen sling was placed in 20 and a silicone mesh sling was placed in 16. The sling was placed at the bulbar urethra and secured to 3 titanium bone screws anchored into the medial aspect of bilateral inferior pubic rami. RESULTS: Results at 12 months were compared. In the dermis group 9 (56%) patients were cured of incontinence (no pads daily), 5 (31%) had significant improvement (decrease of 50% or more in pads daily) and 2 (13%) had no change in symptoms. In the silicone mesh group 14 (87%) patients were cured of incontinence and 2 (13%) were significantly improved. Results showed that a previously placed artificial urinary sphincter led to poorer outcomes but a history of radiation therapy did not affect results. The most common complication was temporary urinary retention observed in 1 (5%) patient in the dermis group and 2 (12%) in the silicone mesh group. CONCLUSIONS: Early results demonstrate that the male sling is a safe and efficacious treatment option for postprostatectomy urinary incontinence. This study demonstrates superior outcomes with the synthetic silicone mesh sling compared to the porcine dermal collagen.

Corporeal plication for the treatment of congenital penile curvature.

PURPOSE: We evaluated the long-term outcome, effectiveness and patient satisfaction of corporeal plication for the correction of congenital penile curvature. MATERIALS AND METHODS: A total of 25 patients with congenital penile curvature were included in the study. Mean age was 39 years (range 15 to 45). Patients with Peyronie's disease, and/or chordee associated with hypospadias or evidence of erectile dysfunction were excluded from analysis. All procedures were done on an outpatient basis using local anesthesia. The technique of corporeal plication consists of placing longitudinal plication sutures of 2-zero braided polyester on the opposing side of curvature until it is corrected during artificially induced erection. A standardized questionnaire was then completed via telephone interview to assess results as well as the patient satisfaction rate. RESULTS: A total of 22 patients were available for evaluation. Successful results at up to 3(1/2) years (range 1 to 42 months, mean 18) of followup were achieved in 21 of the 22 patients (95%). Success was defined as the correction of curvature and a patient satisfaction rate of 75% or greater. Curvature was ventral in 20 cases, dorsal in 2 and left lateral in 3. Shortening of the penis after surgery was noted by 4 patients (18%), of whom 3 nevertheless had a satisfaction rate of 75% or greater. In 2 patients postoperative hematoma resolved spontaneously. Mean operative time was 50 minutes and 22 of the 25 patients (88%) received local anesthesia. CONCLUSIONS: Corporeal plication is a simple, minimally invasive surgical procedure that proved to be effective for congenital curvature of the penis compared with other, more extensive penile reconstruction surgery.
