Abstract Objectives To asses the impact of augmentation enterocystoplasty on the success of cadaveric renal transplantation in patients with dysfunctional bladders. Patients and methods Between 1980 and 2001, 3 men and a woman with severe dysfunctional lower urinary tract underwent a total of 4 cadaveric renal transplantations. The etiologies of the bladder dysfunction were bladder contraction secondary to urinary tuberculosis in all cases. In 3 patients were performed an enterocystoplasty with ileocecal segment and one with ileon. Results The overall allograft survival was 58.7 months. Two patients have functioning grafts 27 and 74 months after transplant, 1 has died due to an intestinal disease and other had crohnic rejection after follow-up of 98 months. Technical complications occurred in 3 patients. All patients remain continent without catheterization after the transplantation. Conclusions Enterocystoplasty is a safe and effective method of restoring lower urinary tract function in the patient with end stage renal disease and a small non compliant bladder.
