Distension methods of surgical correction of hypospadias in boys

Abstract

Difficulties in the treatment of hypospadias in boys persist to this day. After surgical correction of hypospadias, fistulas, strictures, urethral diverticula, retraction of the meatus, glans dehiscence and other complications occur. At the same time, it is quite difficult to understand the whole variety of proposed methods for correcting hypospadias, which creates confusion for specialists and negatively affects the results of treatment. The literature describes more than 300 different methods of correcting hypospadias, but none of the methods is perfect, and there are no generally accepted treatment standards. Despite this, it is an established fact that the choice of the surgery procedure depends on the type of hypospadias. A successful technique of hypospadias repair should be completed with a good cosmetic and functional result. The article presents an overview of the distension techniques of urethroplasty. For the first time, the experience of urethral advancement was presented at the end of the XIX century, but the technique was unpopular and did not have significant success. However, by the end of the XX century, more effective distension techniques of urethroplasty began to be developed, which were widely used around the world (Koff S.A., Ti-Seng Chang, Belman A.B., MAGPI, LUM, etc.). According to scientific literature, urethral advancement is a safe and reliable way to correct distal hypospadias, and it is considered as an alternative to creating a neourethra. This technique has many competitive advantages, such as the short operation time, the absence of urethral tubularization, excellent functional and cosmetic results, and a small number of complications. It, therefore, follows that distension techniques of urethroplasty are considered a good option for correcting distal hypospadias, which should be in the arsenal of every pediatric surgeon and urologist.
