Methods： One thousand two hundred patients between the age of 5 and 95 years underwent circumcision using this procedure in the 2-year period between October 2005 and September 2007. Of these cases, 904 had excess foreskin and 296 were cases of phimosis. Results： In 96.33% of the cases the incision healed, leaving a minimal amount of the inner foreskin with no scarring and producing good cosmetic results. There were no incidents of device dislocation or damage to the frenulum. The average operative time was 2.5 min for excess foreskin, and 3.5 min for phimosis. During the 7 days of wearing the device, mild to moderate edema occurred in 10.08 % of cases with excess foreskin and in 2.58 % of those with phimosis. Edema in the frenulum was seen in 1.67% of patients, and only 0.67% had an infection of the incision. A total of 86.25% of patients reported pain due to penile erection. After removal of the device, 0.58% of the cases had minimal bleeding around the incision, and 2.42% had wound dehiscence. Conclusion： The new device can be applied to an overwhelming majority of patients with phimosis and excess foreskin. This technique is relatively simple to perform, and patients who underwent this surgery had very few complications. Antibiotics were not required and patients reported less pain than those who were circumcised using conventional methods. Circumcision with this device requires minimal tissue manipulation, and is quicker and safer than circumcision using conventional techniques.展开更多

Methods： In three rabbits, autologous foreskin epidermal cells were isolated, expanded in vitro, and seeded （inoculated） onto a tubular acellular collagen matrix, acquired from allogeneic rabbit bladder submucosa. A urethral mucosal defect was created, and urethral reconstruction was performed with the tubular acellular collagen matrix seeded with epidermal cells. Results： On gross examination at 12 months following the procedure, the mucosa of the urethral grafts appeared lubricous and smooth. Urethrography showed that a wide urethral caliber had been maintained without any sign of strictures. Histological examination showed a transitional cell layer in the graft without evidence of a margin between the graft and the host tissue at 12 months postoperatively. Conclusion： Epidermal cells seeded onto acellular collagen matrices can be successfully used to reconstruct urethras that have defects and are transformed to transitional epithelial cells.展开更多
