BACKGROUND: Pediatric urologists tend to use one-stage procedures for the repair of @entity2650 . As there are various types of @entity2650 , we cannot repair this disease with a single modality. It is difficult to estimate the exact length of the neourethra in cases of severe @entity2650 before surgery. METHODS: After a circumferential incision is made about the coronal sulcus and the chordee is completely released, the distance between the glans tip and the retreated native meatus is measured to determine the length of the neourethra. Urethroplasty with the method of Transverse Preputial Island Flap (TPIF) is selected when the distance ranges from 3 to 4 cm, while urethroplasty using with modified OUPF IV (Koyanagi) is selected in cases of more than 4 cm. RESULTS: We performed surgery on 14 hypospadiac @entity1 with chordee between April 1996 and April 1997. Eight @entity1 underwent urethroplasty using the TPIF method and 6 underwent urethroplasty with the method of the modified OUPF IV. With the TPIF methods, 7 to 8 @entity1 underwent repair successfully and one experienced urethrocutaneous @entity292 , while 5 of 6 treated by the modified OUPF IV method has successful repairs and @entity850 occurred in one @entity1 . CONCLUSION: Even if we encounter severe @entity2650 , we can treat these @entity1 with one stage repair alternatively. A relatively high success rate was obtained with both methods to repair severe @entity2650 .
