    ABSTRACT: The surgical treatment of hypospadias contains urethral reconstruction and correction of penile curvature. In some severe type of hypospadias, it also needs correction of penoscrotal transposition and cleft of scrotum. However, there are few literatures that refer to the correcting of deformity of glanular dislocation.

    ABSTRACT: After patients with congenital microtia receive external ear canal plasty, the mastoid area usually has insufficient space for ear reconstruction. Hence, after ear reconstruction, an inferoposterior position deformity of the ear appears to some extent. Using inverted U-shaped purse and rotation flaps can correct this deformity effectively. From May of 2009 to September of 2011, five patients received the described procedures in the authors' department. Inverted U-shaped purse and rotation flaps were used for all the patients. The inverted U-shaped purse flap was used to reduce the area of the canal orifice and to lower the position, and the rotation flap was applied to turn the ear in a more superoposterior position. Two patients also received full-thickness skin grafting to cover the secondary wound. In four patients, V-Y-plasty or Z-plasty was used to adjust the flap transition. For the five patients, the distances between the ear antihelix and canal orifice were shortened, and the areas of the canal orifice were diminished. The retroversion of the auricle was corrected in various degrees, and the angles of the long axis of the auricle and the horizontal line were increased an average of 14.4°. The vertical distance between the top of the helix and the center of the canal orifice was increased an average of 15.2 mm. A slight dog ear deformity in front of the crus of the helix was left after the operation, but it was alleviated in the follow-up period. By using inverted U-shaped purse and rotation flaps, the inferoposterior position deformity of the reconstructed ear after external ear canal plasty in congenital microtia can be resolved effectively.

    ABSTRACT: • To investigate the feasibility of tissue-engineered corpus cavernosum (TECC) with muscle-derived stem cells (MDSCs) as seed cells and determine the growth potential in vivo. • Acellular corporal collagen matrices (ACCMs) were obtained from adult rabbit penis by a cell removal procedure. MDSCs were separated and purified using a digestion method and Preplate technique, then seeded on ACCMs at a concentration of 30 × 10(6) cells/mL to construct TECCs. After 5 days of culture, seeded ACCMs were implanted with albuginea of rabbits. The implants were retrieved at 2, 4 and 6 months after implantation. • Histochemistry, immunohistochemisry and scanning electron microscopy were performed to analyse the morphological characteristics of the TECCs. • The decellularization process successfully extracted all cellular components while preserving the original collagen fibres. • Histological analyses of the explants at all time points in the experimental group had more cells and better arranged growth than the control group. α-Smooth muscle actin and endothelial nitric oxide synthase-positive cells were more prevalent in the experimental group. • Our study showed that MDSCs can be seeded on three-dimensional ACCM scaffolds and develop tissues that are similar to native normal corpus cavernosum.

    ABSTRACT: To evaluate the effect of niti-alloy urethral stent on the prevention of urethrocutaneous fistula and urethral stricture in hypospadias repair. From January 2001 to December 2004, niti-alloy urethral stents were applied to repair congenital hypospadias in 63 patients. Among 63 patients, 49 (19 cases of proximal hypospadias, 22 cases of penoscrotal hypospadias and 8 cases of perineoscrotal hypospadias) received one-stage surgical managements of urethral reconstruction, and 10 underwent postoperative fistular repairs and 4 received repeated urethral reconstruction because of urethral stricture after hypospadias repair. All patients gained healing by first intention without fistula or urethral stricture. The stents were left indwelling in the neourethra for 2 months to 3 months to prevent stricture. The longest indwelling period was about 1 year. No dysuria or other discomfort occurred during this period. Niti-alloy urethral stent can effectively prevent the postoperative urethrocutaneous fistula and urethral stricture after hypospadias repair.
