Parents often ask at the specialist’s office, “What type of hypospadias does my child have?” or “What type of hypospadias does my child have? or “My child has a mild hypospadias, right? It should be easy to treat.” To understand this question, it is important to know how hypospadias is classified and how it relates to surgical treatment. The staging of hypospadias has been described since the beginning of medical interest in hypospadias, and the staging methods are not exactly the same from scholar to scholar. There are simply three types, such as light, medium, and heavy, or called glans, penis, and perineum. There are also those divided into four degrees: I0 refers to the opening of the urethra at the head of the penis or the coronal sulcus, II0 at the body of the penis, III0 at the scrotum of the penis, and IV0 at the perineum. These are named based on the location of the urethral opening in its natural state and do not reflect the length of the urethral defect. The surgeon is more accustomed to using a typology that reflects the true extent of the condition or the length of the urethra that needs to be surgically reconstructed after the inoperable prosthetic urethra has been abolished and the penile curvature has been corrected, based on the retraction of the urethral opening to a specific location. The more commonly used Barcat typing method is introduced here. The classification is divided into three types in general, and each type also includes subtypes. Specifically: 1. Anterior hypospadias: This includes the external urethral opening at the level of the glans, the coronal sulcus and the first 1/3 of the penile body. 2.Middle type hypospadias: The external urethral opening is located within the middle 1/3 of the penile body. 3.Posterior hypospadias: It includes the external urethral opening located in the posterior 1/3 of the penile body, at the root of the penis, and at the perineum of the scrotum. Parents usually think that light cases are well treated and heavy cases are difficult to treat. In fact, the treatment of hypospadias is troublesome, and there is no equivalence between the degree of difficulty and the classification. In particular, typing by the location of the abnormal opening in its natural state before surgery can only be a description. After the correction of the lower curvature during surgery, the typing is based on the actual position of the external urethral opening to reflect the length of the defective urethra. In general, the more posterior the urethral opening is, the longer the urethral defect is, and the longer the replacement urethra needs to be made from other materials during surgery, which makes the surgery more troublesome and may result in more post-operative complications, thus increasing the chance of multiple surgeries. There is also a relationship between the length of the urethral defect and the surgeon’s choice of a one-stage or staged surgery plan, with posterior hypospadias requiring more staged surgery. It is not necessary to look deeper into these knowledge about suburethral clefting, and parents should not simply understand that the anterior type is well treated and the posterior type is difficult to treat. In fact, the surgeon will choose the surgical plan and the specific surgical procedure according to the specific development of the child’s penis, the amount of urethral defects, and the degree of affluence of the surrounding materials that can be used instead of the urethra, in order to achieve the best final result, rather than aiming for the least number of surgeries.
