Technique for intraoperative localization of urinary leakage

Abstract

Urinary leakage is an uncommon complication of renal transplantation with a near equal division occurring between ureteral and bladder origins. The diagnosis is usually entertained from a characteristic clinical course and confirmed by preoperative contrast cystography or radionuclide scanning. A technique for precise intraoperative localization of the site of urine extravasation using intracystic instillation of Intralipid has been described. It allows easy recognition without damaging or staining surrounding tissues. In addition, this technique may be applied in other situations to confirm anastomotic or hollow viscus closures.
