[Selective bladder preservation in muscle-invasive bladder cancer by transurethral resection combined with intravesical instillation therapy: analysis of clinical effect in the elderly].

To explore the therapeutic effect and quality of life in elderly patients of muscle-invasive bladder cancer by transurethral resection combined with intravesical instillation therapy.From January 2005 to January 2015, 136 cases were diagnosed with T2 bladder cancer by transurethralplasmakinetic therapy or transurethral laser therapy. The data of 136 cases were analyzed retrospectively.In transurethralplasmakinetic therapy group, the overall survival rate was 73.3%, the cancer-specific survival rate was 85.6%, the average survival time were 65 months. In transurethral laser therapy group, the overall survival rate was 73.9%, the cancer-specific survivalrate was 87.2%, the average survival time were 70 months. Two methods also can improve the patient's quality of life.For the aged with invasive bladder cancer (T2), we could try the transurethral resection combined with intravesical instillation therapy.
