Objective: To introduce a kind of method of hypospadias comprehensive typing, approach correlation of the characteristic of urethra plate growth and the operation method choice for hypospadias repair,

Methods: 180 patients suffering of hypospadias were assessed in accordance with the classification of hypospadic orifice and urethral plate and chose their methods of operation accordingly, among which 89 patients accept Tubularized Incised Plate Plasty (TIP), 48 patients accept Mathieu plasty, 36 patients accept Onlay plasty and 7 patients accept Koyanagi plasty.

Result: In the 180 cases, the total occurrence rate of urethral fistula was 5.56% (10/180), the occurrence rate of urethral stricture was 3.89% (7/180), the cure rate of one stage operation was 90.56% (163/180), the reoccurrence rate of clubbed penis was 4.44% (8/180), the occurrence rate of poor development of penis was 2.22% (4/180), the occurrence rate of poor appearance of penis was 2.78% (5/180), with overall satisfaction rate was 90.56% (163/180). 12.78% (23/180) of the patients required two stage operation. There was no significant difference on the cure rate of one stage operation among different operation methods chosen (p>0.01). The cure rate in patients with one stage operation from the <6 months group was better than that from the >6 months group (p<0.01).

Conclusion: According to the characteristic of urethral plate and the classification of hypospadic orifice to make synthetic typing to hypospadias can elevate surgical operation success rate.
