Caliceal Urinary Fistula in Renal Allotransplantation

“…The clinical picture of a caliceal fistula classically consists of fever with abnormal swelling and tenderness usually occurring in the imme diate postoperative period but sometimes delayed for several weeks [32], Non-preexisting arterial hypertension can be an alarm symptom [27], When the diagnosis is not yet obvious by urinary leakage, intra venous (high dose) or retrograde or antegrade pyelography can be helpful [39], although radionuclide studies may be the first choice of diagnostic procedure for urinary extravasation [3,20,44], Recent advances in the technology of vascular and microvascular surgery enable uncomplicated reconstruction of multiple renal ves sels in renal transplantation [18]. However, when an ischemic zone is seen during the operation the repair can be difficult [43].…”
