A report is presented on 95 ileal conduit operations. Of these cases 16 had either neurogenic bladder disorders or shrunken bladder after radiation therapy and 79 had carcinomas of the bladder without radiotherapy. 19 of the latter patients were treated palliatively with an ileal conduit without cystectomy, whereas the remaining 60 patients underwent ileal conduit including total cystectomy. Early complications were seen in 42% and late complications in 27% of the patients. The 5-year survival rate for all stages of carcinoma was 34% and the 10 years survival rate was 18%. There is a definite relationship between reduced survival rates in cases of increased tumour staging and grading.
