INTERPOSITION OF ILEUM IN THE URETER - A CLINICAL-STUDY WITH LONG-TERM FOLLOW-UP

Objective To present the long-term results of the interposition of ile um in the meter. Patients and methods An ileal loop was interposed to replace a long defect of the upper meter, with preservation of lower u reteric continuity, in nine patients (mean age 35 years, range 18-58). Patients were followed regularly for a mean of 5.2 years (range 2-7) and assessed using renal ultrasonography, isotopic renography and intr avenous urography. Results Urinary drainage was satisfactory and renal function and configuration were improved. None of the patients experi enced metabolic acidosis or electrolyte disturbances despite receiving no medication. Conclusion These results were encouraging and further clinical experience is needed to confirm that ileal interposition of t he meter is a safe and effective procedure.
