Novel Ureteroscopic Technique for Treatment of Prolonged Caliceal Leak After Partial Nephrectomy

Abstract

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.
