[Analysis and prevention of postoperative complications of tubularized incised plate urethroplasty for hypospadia].

ABSTRACT

OBJECTIVE: To explore the reasons and preventions of complications of tubularized incised plate urethroplasty technique for hypospadia repair. METHODS: In the study, 54 patients of 247 hypospadia patients were analyzed who had complications, using SPSS 13.0 statistics to compare their complications with anatomy reasons including positions of the meatus, development of urethral mucous membrane and glans penis and degrees of ventral curvature. RESULTS: (1) Postoperative complications were relative to the position of meatus. The closer urinary meatus was to the coronary sulcus, the higher complication rate would be(χ(2)=26.309, P<0.01).( 2) The complication rate of normal glans penis was lower than that of the small glans penis (χ(2)=23.709, P<0.01). (3) The well developed urethral mucous membrane had a lower complication rate(χ(2)=12.086, P<0.01). (4) When the angle of ventral curvature was larger than 30°, a higher complication rate occurred(χ(2)=10.233, P<0.01). CONCLUSION: Tubularized incised plate urethroplasty procedure for single-stage urethroplasty is the first choice for patients with big glans penis, normal development of urethral plate and slight curvature so as to achieve high curing rates and good shape of penis.
