Scrotal midline ultra-long flap urethroplasty

Urethral formation with scrotal flaps has been reported, but occasionally distal ischemic necrosis. In recent years, it has been reported that the use of a flap containing a meat membrane can avoid this deficiency. Although some cases appear bloated early in the postoperative period, it may not be obvious in the later stage. In some cases, the flap is not long enough to extend to the perineum or thigh root, and the extension should be delayed first. Treatment of diseases: hypospadias of children with hypospadias Indication Have a hypospadias. Preoperative preparation First, we must identify the gender. Secondly, the perineum should be cleaned with 1:1000 Xinjieer liquid on the 3rd day before surgery, once every night for 10 minutes. The area was shaved 1 day before surgery. People with urinary tract infection should first control the infection. Surgical procedure 1. Position: flat supine position, legs are slightly separated or cut off. 2. Incision: The catheter is placed in the urethra to support the catheter. Then, a tongue-shaped flap extending along the midline of the scrotum from the circumference of the urethral orifice was cut out to a width of 2 cm, and the length was 1 to 2 cm longer than the distance from the urethral opening to the tip of the penis head. The thickness included the meat layer. 3. Straighten the penis, the urethra is fully loosened, and the penis is straightened (with the penis straightening). The flap is lifted and wrapped around the catheter to form a tube with the wound facing outward. Use a 5-0 nylon thread or silk thread. Intermittently sutured into a reconstructed urethra. The external urethral opening is fixed to the tip of the penis head, and the catheter is fixed by suture. The reconstructed urethra is fixed with a number of sutures between the two corpus cavernosums. 4. Closing the wound surface: After adjusting the skin edge according to the z-forming principle of the penis skin, the suture is intermittently sutured into a zigzag shape. After the skin edge of the scrotum is pulled up and sutured, the rubber strip can be placed. After covering the incision with iodoform Vaseline gauze, the thick layer of dressing is pressure wrapped.
