[Carcinoma of the urinary bladder. Konservative oder operative Therapie bei PT1G3].

As no prospective randomised studies are available on therapy and outcome in T1G3 carcinoma of the urinary bladder, a decision on therapy can only be made on the basis of retrospective studies or with reference to the individual experience of a particular urologist. In this paper the advantages and disadvantages of primary cystectomy and of transurethral resection, both alone and in combination with BCG instillation, are discussed and compared.
