Novel ureteroscopic technique for treatment of prolonged caliceal leak after partial nephrectomy.

Introduction and Objectives: Caliceal leak after partial nephrectomy (PN) typically resolves with conservative management. However, persistent fistulae pose a formidable challenge that may require additional therapeutic actions. Methods: We describe a case of a patient with a solitary kidney who suffered a persistent urine leak following PN. A novel retrograde ureteroscopic approach was taken that utilized the combined techniques of caliceal fulguration and fibrin glue injection. Results: Imaging demonstrated resolution of the caliceal fistula at 13 months postoperatively. Conclusions: Persistent urine leak after PN remains a burdensome complication that often requires creative steps to resolve. Our case presents a solution using a novel ureteroscopic technique.
