Body composition changes measured by dual-energy X-ray absorptiometry in patients receiving home parenteral nutrition

Some patients with infiltrant vesical cancer can be treated successfully with radical cysto-prostatectomy and urinary by-pass and increasingly more authors publish successful results in series of selected patients over 70- and 80-year old. Between February 1988 and July 1996, 18 radical cystectomies with orthotopic urinary by-pass were performed in the Urology Service, Policlinico Vigo, in patients over 70 (range 70-84 years), with an operative mortality rate of 11%. 8 patients (44%) developed immediate complications and 9 patients (50%) presented distant complications. Overall mortality in our series was 33.3% and survival 66.6% after a mean follow-up of 30.7 months. We believe orthotopic-continent by-pass is a valid alternative with operative mortality and complication rates similar to those of ileal ducts, with the advantage for the patient of avoiding permanent urinary stoma.
