Abstract: Objective:To improve the diagnosis and treatment of nonurothelial cancer of the bladder.Methods:Fifteen cases of nonurothelial cancer of the bladder were reviewed.The diagnostic methods included ultrasound,pelvic CT scan,cystoscopy and biopsies.Partial cystectomy was performed in 14 cases,and radical cystectomy in 1 case.Results:Adenocarcinoma was observed in 11 cases,and squamous cell carcinoma in 4 cases.The mean survival time was 15.6 months.Conclusions:The nonurothelial bladder cancer is rarely seen.It's highly malignant and has a poor prognosis.Early diagnosis and surgical treatment are essential.Radical cystectomy is recommended as the first choice for treatment of the disease.
