Patients with hypospadias, especially those with severe hypospadias, go to the hospital to see a physician, some of whom say that there are no beds available, and some say that the surgery should be staged. What exactly is the case to be staged and what can be done in one stage? 1, the vast majority of suburethral cleft can also be operated in one phase. For the operator, staged surgery breaks down a difficult action into two actions, relatively easy and simple; for patients and families, staged surgery will be subjected to two anesthesia and surgical risks, the cost and hospital stay and the pain endured increases. In fact, many experienced surgeons will try to consider one-stage surgery because the success of a complex operation will give the surgeon a great sense of accomplishment and also save the patient money and time and reduce pain. Even if a urinary fistula occurs after one surgery, the second surgery is relatively simple. This is because the risk of a second surgery in a staged procedure is the same as that of a phase of surgery for others, and is equally prone to complications. 3, with the improvement of technology, the original need for staged surgery may not need to be staged now: in the past, the penile scrotum skin source is not enough to require staged surgery, but now with the improvement of technology, the application of oral mucosa and various skin piece technology, so that many patients who need staged surgery can be operated in one phase. What are the conditions that require staged surgery? Adults with posterior hypospadias with severe curvature, good penile development and tight skin source; patients with hypospadias with severe infection and stricture after multiple surgeries; patients with poor bilateral scrotal development or with bilateral cryptorchidism, obvious penile scrotal transposition along with severe curvature. Other special cases.
