Abstract
Hypospadias is a common birth defect of the male external genitalia. However, there are conflicting arguments about the optimal classification approach and ideal surgical technique. We have introduced the Plate Objective Scoring Tool (POST) to define critical glanular phenotypic landmarks of the urethral plate. We propose that POST can objectively, reproducibly, and accurately determine urethral plate quality, thus permitting robust comparison between the different surgical techniques commonly utilized in hypospadias repair. Furthermore, the POST scoring system represents a versatile tool that can objectively quantify key variables in hypospadiology that are currently not well defined. Further validation of POST should lead to better identification and management of postoperative complications.

Summary
Hypospadias is considered a common birth defect of the external genitalia of boys.[1,2] several controversies surround the different classification approaches and ideal surgical techniques for correction.[3] We have introduced the Plate Objective Scoring Tool (POST) to define critical phenotypic landmarks of the urethral plate (UP) within the glans. The area from A to B is the extent of the neo-meatal opening, while B to C is the extent of the vertical glanular fusion line. Having identified these reference points, the ratio (AB)/(BC) defines POST value, which represents urethral impression within the glans penis and overall quality of the urethral plate. Lower AB/BC ratio could represent an earlier stage of urethral development and more severe phenotypical stages
