“…Image-guided percutaneous biopsy of the upper urinary tract collecting system appears to be a safe and effective alternative in selected patients who underwent unsuccessful ureteroscopy or who are inadequate candidates for this procedure. In selected patients who do not have a double J catheter, insertion can be performed using the percutaneous technique ( 18 ) before biopsy.…”

Urothelial carcinoma is a rare malignant neoplasm, accounting for only 5% to 7% of kidney tumors and 5% of urothelial tumors. During the management of urothelial carcinoma, anatomopathological evaluation is used for stratifying the tumors into different prognostic groups to aid in the evaluation of treatment results and to optimize the management of patients. Percutaneous image-guided biopsy is a safe and feasible procedure, with high sensitivity and accuracy rates. Although image-guided percutaneous biopsy of the urinary tract is a relatively uncommon procedure, it can be considered an option in selected cases or when traditional methods, such as the ureteroscopic technique, are not possible.

“…Hemorrhage is a common complication, with a reported incidence of up to 6% ( 1 ) . Bleeding occurs most commonly due to lesion of the anterior or posterior segmental arteries, which can be prevented by performing a posterolateral renal puncture, along the avascular plane known as Brödel’s line ( 7 , 8 ) . Clinically, it can manifest as macroscopic hematuria, with variable severity of bleeding, some patients progressing rapidly to hemodynamic instability and (in cases of a high-flow AVF) heart failure ( 2 , 4 , 5 ) .…”

Objective: To identify the main hemorrhagic complications after percutaneous nephrolithotomy, as well as the results obtained with transcatheter arterial embolization (TAE) at an interventional radiology center. Materials and Methods: This was a retrospective analysis of patients undergoing TAE for the treatment of hemorrhagic complications after percutaneous nephrolithotomy. All patients underwent computed tomography angiography (CTA). Results: We evaluated a total of nine patients. At emergency department readmission, the most common symptom was macroscopic hematuria, which was seen in five patients. Three patients had an isolated pseudoaneurysm, two had a pseudoaneurysm together with active bleeding (perirenal hematoma), and one had a pseudoaneurysm together with arteriocalyceal fistula. Arteriovenous fistula was diagnosed in three patients and was not seen in combination with other vascular lesions. We did not identify arteriocalyceal fistula in isolation. Five patients underwent TAE with 6 × 15 mm and 6 × 20 mm microcoils. Four patients underwent TAE with n-butyl-2-cyanoacrylate and ethiodized oil. Follow-up CTAs revealed no complications. Conclusion: Because of its high diagnostic accuracy, CTA provides the interventional radiologist with valuable data for individualized therapeutic planning. The TAE procedure is safe and effective. It can therefore be used as a first-line treatment for hemorrhagic complications resulting from percutaneous renal procedures.
