Experiences are discussed in the treatment of vesical sequelae from tuberculosis through ileocecocystoplasty, using Gil Vernet's technique, which provided for a satisfactory evaluation in seven of the eleven cases treated. The complications included, among others, two cases of transitory renal insufficiency, one transitory vesicocutaneous fistula, and one abscess of the operative wound. In all cases, the patients suffered from pre and postoperative urinary infections, which resisted treatment, and which could only be cured in two cases. In all the patients, a considerable increase in vesical capacity was achieved. Nevertheless, better results should be expected when the operation is done at an earlier stage.
