[Island flap in the surgical treatment of hypospadias].
Surgery of hypospadias represents an interesting field of innovatory ideas. Many methods may be suitable and many modifications can be performed. There is no one method for all kinds of hypospadias. It is necessary to find the right method for each patient. The result often depends upon the experience of the surgeon with a particular method. The choice between straightening and urethroplasty in one or two stages depends on cost-benefit ratio and evolution at distance of the straightening must be taken into account as well tissue consumption imposed by the urethroplasty, with one stage straightening that makes reintervention very difficult. In the latter case, a multi-stage operation will be necessary with flaps for urethroplasty after the straightening, or, in a more developed penis, a shortening operation according to Nesbit. With two-stage method, in case of relapsed curvature, this can easily be treated, if tissue is available. For a good result of urethroplasty the ability of surgeon, a constant calibration of the canal, plenty of elastic tissue for the neo-urethra, care not to suture on these planes, are highly important. In our opinion Duplay's method observes these requisites. Two-stages surgery allows easy correction of any eventual relapsing incurvature, with no problems for the following urethroplasty. One-stage surgery allows the problems to be resolved in a single surgical Step, but involves the risk of tissue consumption and proximal stricture.
