title: Novel ureteroscopic technique for treatment of prolonged caliceal leak after partial nephrectomy.
abstract: OBJECTIVE
  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.
