Tissue engineered patch treatment of the urinary leakage after hypospadias repair / 中国组织工程研究

ABSTRACT

BACKGROUND: The hypospadias is usually repaired by the autologous tissues by surgery, but there is few local tissues available in patients with urinary leakage after I stage surgical repair, while other tissues require complex operations and induces large injury.OBJECTIVE: To observe the tissue engineered patches in the treatment of hypospadias, and to evaluate the biocompatibility and clinical efficacy.METHODS: Eight patients with urinary leakage after surgery for hypospadias repair underwent tissue patch I stage urethroplasty from January 2009 to October 2010. The curative effect and perioperative histocompatibility were determined.RESULTS AND CONCLUSION: Eight patients were uniformly successful after I stage surgery. One out of the 8 patients appeared mild urinary leakage and well cured by topical fibrin glue. There was no fever, local edema, skin tube and flap necrosis occurred during the postoperative hospital stay. All patients were followed up for 4-6 months, patients were observed to urinate standing, without urinary leakage, refractory prepuce edema and other complications.
