Hypospadias is a common congenital malformation of the male urinary tract, characterized by high morbidity, complicated surgical methods, and a high failure rate. Currently, it is mostly operated in stages, with penile correction followed by urethral repair, which has more complications and high costs. In our hospital, from March 2001 to October 2001, we performed a one-stage repair of hypospadias with a tipped transfer flap in three young patients, and combined with the corresponding perioperative management, the surgical results were good without any complications. The results were good without any complications. The following is a report. The three children were 2, 3, and 4 years old, respectively. The 2-year-old child had penoscrotal hypospadias and the other two had penile hypospadias. The children with penile hypospadias were treated with a dorsal cover urethroplasty (Onlay) with a tip transfer flap. A 5-mm wide flap of skin was cut with gentian violet at the urethral opening and the tip of the glans as the ventral urethra, and a circular incision was made under the coronary sulcus along this area, and the penis was fully freed under the deep fascia to the root, taking care not to damage the blood vessels. The skin flap with the tip was cut along the mark, and the skin layer was carefully separated from the superficial fascia along this gap, taking care not to damage the skin piece and superficial fascia vessels, and the F8 pure silicone double-lumen balloon catheter was inserted, and the two skin layers were interrupted and sutured with 6-0 Dixon absorbable thread at a spacing of about 2 mm, and the proximal end was anastomosed with the urethral orifice, and care was taken to cut away the membrane component of the original urethral orifice that was not a sponge body. When the suture reaches the coronal sulcus, the glans is incised along the ventral side, deep to the white membrane, at which point the blood flow is blocked and timed with a tourniquet at the root of the penis to complete the dorsal and ventral anastomosis of the urethra and make an intact urethra, the incised glans is anastomosed ventrally, the tourniquet is released, the foreskin is anastomosed to the coronal sulcus incision, the ventral side covers the urethra completely, and the anastomotic line of the skin pieces is staggered with the urethra with attention to tension-free sutures, wrapped with gauze of appropriate tension penis, and the urethral orifice was coated with gentamycin ointment. In children with penile scrotal hypospadias, urethroplasty was performed with a tipped scrotal flap and a tipped transfer flap urethral canal method (Duckett) because the urethra was missing up to 6 cm. In all three cases, the gauze was completely saturated with sterile paraffin oil after four days and removed after five days. The urinary catheter was removed after ten days. All three cases were operated successfully without any complications and were functionally and cosmetically satisfactory. There was no urethral stricture or functional disorder in the postoperative follow-up. Hypospadias is a male congenital anomaly, which is autosomal dominant, and there is one case in about 125-250 newborn male infants. The incidence of hypospadias can be increased by the use of courtship hormone and progesterone during pregnancy. Hypospadias is often complicated by inguinal hernia and cryptorchidism, and the more proximal the urethral orifice is, the higher the incidence of combined malformations. Treatment is mainly surgical, with the aim of correcting the downward curvature of the penis, restoring the normal position of the urethral opening, being able to urinate standing up, and having fertility in adulthood. In the past, staged surgery was mostly used, with more than 200 surgical methods and a high incidence of complications. Therefore people are always exploring new surgical approaches. Back in the 1940s, almost all tissues that could replace the urethra were used, such as arteries, veins, appendix, scrotal skin, buccal mucosa, foreskin, hairless skin of various body parts and bladder mucosa. The current unified view is that the foreskin is preferred, and if the urethral defect is long and the penile foreskin is relatively insufficient, the bladder mucosa and scrotal skin may be used. We use the Onlay and Duckett procedures, which have fewer clinical complications, to complete both penile correction and urethroplasty in one operation. Since the penile skin has a good blood supply, the survival rate of the tipped flap is high and scar contracture is not easily formed. Since the flap is not in a vertical plane with the white membrane of the penis, the penile fascia and the sutures of the skin layers after transfer, the chance of the most common complication, urethral fistula, is reduced. Intraoperatively, the F8 double-lumen pure silicone catheter was used as a stent, not cystostomy, which caused less irritation to the urinary tract and less secretion, thus reducing the chance of infection, and the urethral suture was made of Dixon absorbable thread with the best histocompatibility, which also reduced the occurrence of urinary fistula. Since the procedure is completed in one visit, the pain and cost of the child is reduced. We believe that the selection of an appropriate surgical procedure according to different conditions, strict and meticulous operation, and careful care during the perioperative period are all important guarantees for the success of the operation.
