The Application of Skin Expander in Subcontaneous Cystoplasty:A Novel Method to Solve the Dysfunction of Bladder

Abstract

The patients of neurogenic bladder or radical cystectomy suffered much of the bladder dysfunction, leading mass wealth losses and misfortune of individual and society. We designed a new method to solve the problem: subcontaneous cystoplasty. Three skin expanders were buried around the abdominal ureter exit after cutaneous ureterostomy, then the inner skin bag were constructed by the expanded skin. The subcutaneous tunnel connected to the urine bag were pressed outside by belt to control the voiding. Skin urethra bulge, controlling the direction of the urination, located at the terminal of subcutaneous tunnel. Patients can put pressure to the subcontaneous urine bag to exhaust the urine. It may affect the appearance, but it can avoid many defects caused by ileocolic-cystoplasty, and may help neurogenic patients get ride of external urine bags.
