Interposition of ileum in the ureter: a clinical study with long-term follow-up
1Urology and Nephrology Centre, Mansoura University, Egypt.
Objective:
To present the long-term results of the interposition of ileum in the ureter.
Patients And Methods:
An ileal loop was interposed to replace a long defect of the upper ureter, with preservation of lower ureteric 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 intravenous urography.
Results:
Urinary drainage was satisfactory and renal function and configuration were improved. None of the patients experienced 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 the ureter is a safe and effective procedure.
