787 RESURFACING AND RECONSTRUCTION OF THE GLANS PENIS Enzo Palminteri*, Elisa Berdondini, Antonio Vitarelli, Francesco Montorsi. Arezzo, Italy, Bari, Italy, and Milan, Italy. INTRODUCTION AND OBJECTIVE: To describe the techniques and results of surgical reconstruction of the glans penis lesions. METHODS: Seventeen patients (mean age 53.2 years) were treated by resurfacing or reconstruction of the glans penis for benign, premalignant and malignant penile lesions. The aetiology of the lesions was: RQH=RRQ¶VEDODQLWLVIRXUOLFKHQVFOHURVXVRQHFDUFLQRPDin situ¿YH squamous cell carcinoma and six squamous cell carcinoma associated with lichen sclerosus. Five cases were treated using glans skinning and UHVXUIDFLQJFDVHVXVLQJJODQVDPSXWDWLRQDQGUHFRQVWUXFWLRQRIWKH neo-glans and 7 cases using partial penile amputation and reconstruction of the neo-glans. Glans resurfacing and reconstruction were performed using a skin graft harvested from the thigh. RESULTS: The mean follow-up was 32 months. All patients were free of local pre-malignant/ malignant recurrence. Patients who underwent glans resurfacing reported glandular sensory restoration and complete sexual ability. Patients who underwent glansectomy or partial penectomy with neo-glans reconstruction maintained sexual function and activity, although sensitivity was reduced as a consequence of glans/ penile amputation.

METHODS: From June 2002 to December 2003 and from March 2006 to January 2007 total of 36 patients aged 1-22 years (average 7.5) were operated using the concept of TIP urethrolpasty. The hypospadiac meatus were subcoronal in 28 (77.7%), midshaft in 4 (11.11%) and penoscrotal in 4 (11.11%) patients. The standard TIP urethroplasty were performed in the primary cases (26 patients) while in the secondary cases (4 patients) and in the boys who were circumcised EHIRUHDGPLVVLRQ SDWLHQWV PRGL¿HG7,3XUHWKURSODVW\ZHUHXVHG 7KHVWDQGDUGWHFKQLTXHFRQVLVWRI8VKDSHGLQFLVLRQPLGOLQHLQFLVLRQ DQG VXEFXWDQHRXV ÀDS FRYHULQJ 7KH GRUVDO VXEFXWDQHRXV ÀDS ZDV harvested from preputial skin and dissected from the midline then both OD\HUV RI ÀDS ZHUH WUDQVSRVHG WR WKH YHQWUDO VLGH RI WKH SHQLV ZLWK V\PPHWULFURWDWLRQ(DFKOD\HURIWKHVXEFXWDQHRXVÀDSZDVVXWXUHG to the wings of the glans and corpora cavernosa, thus the neourethra EHFDPH FRPSOHWHO\ FRYHUHG ZLWK GRXEOH OD\HUV RI ZHOOYDVFXODUL]HG tissue.

790 MEDIUM-TERM FOLLOW-UP OF DORSAL ONLAY GRAFT URETHROPLASTY USING PENILE SKIN OR BUCCAL MUCOSA IN ADULT BULBOURETHRAL STRICTURES Sao-Nam Tran*, Farshid Fateri, Giordano Venzi, Jose Saldarriaga, Gregory Wirth, Christopher Emmanuel Iselin. Geneva, Switzerland. INTRODUCTION AND OBJECTIVE: The concept of dorsal onlay graft (DOG) urethroplasty was based 10 years ago on providing a better graft bed, which might improve repair longevity in comparison to ventral grafts. Shortly after, buccal mucosa (BM) was reappraised as an eventually more suitable graft material than prepucial skin (PS). The goal of this study is to assess the overall outcome of DOG urethroplasty on a medium term basis, and to determine whether BM is better than PS grafts in such repairs of bulbar urethral strictures. METHODS: From 1998 to 2006, 48 patients with bulbar urethral strictures (>2cm) underwent DOG urethroplasty. PS or BM free grafts were used according to tissue availability and patient preference.

In 52% of cases, a resection-anastomosis of the tightest segment was done. PS graft mean length was 5.9 x 2.7 cm and 5.2 x 2.4 cm for BM graft.
