Katagiri A. A case of refractory urinary fistula after partial nephrectomy treated with additional partial nephrectomy for suspected isolated calix. Int J Case Rep Images 2023;14(2):42–45.ABSTRACT
Introduction: Urinary fistula is the major complication after partial nephrectomy and is occasionally refractory to conservative treatments.
Case Report: A 66-year-old man with renal cell carcinoma was treated with partial nephrectomy. Diagnosis of urinary fistula was triggered by drainage of perirenal abscess after surgery. Being refractory to ureteral stenting, a dilated ventral upper calix was detected in the subsequent fistulography, whereas the calix or its connection with the renal pelvis was not demonstrated in excretion phase of enhanced computed tomography. Considering the possibility of isolated calix due to infundibular injury besides the fistula communicating with the renal pelvis, we performed additional partial nephrectomy for the upper pole kidney and immediately closed the collecting system. The drain could be removed thereafter.
Conclusion: We report the first case of refractory urinary fistula after partial nephrectomy treated with additional partial nephrectomy.
