Aims. To identify the most appropriate surgical strategy for carcinoma of the urachus.Methods. Analysis of a case of adenocarcinoma of the urachus and an examination of the current literature were carried out.Conclusions. Partial cystectomy is considered the most appropriate surgical strategy but the need for close follow-up is underlined.

PURPOSE:We compare the absorption of D-xylose and vitamin B12, and the metabolic status in ileocecal and ileal orthotopic neobladders.MATERIALS AND METHODS:D-xylose plasma levels after an oral load, body composition, plasma vitamin B12, acid base and electrolyte balance were studied in 33 patients with an ileocecal reservoir and 13 patients with an ileal reservoir. Mean followup was 55 months. Results of both types of operation and a healthy control group were compared.RESULTS:Plasmic levels of D-xylose and vitamin B12 were significantly lower in the ileal reservoir than in ileocecal reservoir group and normal controls.CONCLUSIONS:Despite an acceptable body composition, intestinal malabsorption could be present in patients with an ileal reservoir but the ileocecal tract appears to be safe.
