What the radiologist should know about the role of interventional radiology in urology

Abstract

Interventional radiology has been constantly developing in terms of the techniques, materials, and methods of intervention. It interacts with all areas of medicine, always with the ultimate goal of ensuring the well-being of patients. Advances in imaging techniques, especially in the last two decades, have led to a paradigm shift in the field of urological imaging interventions. Many urologic diseases that were previously treated only surgically can now be effectively managed using minimally invasive image-guided techniques, often with shorter hospital stays and requiring only local anesthesia or conscious sedation.

Percutaneous access for the diagnosis of urothelial neoplasms: pictorial essay with anatomopathological correlation

“…Thus, although ureteroscopy remains the gold standard, it can be technically challenging and is associated with significant rates of false-negative results, depending on the morphological characteristics of the lesion ( 4 ) . Several image-guided interventional techniques have been evaluated in Brazilian radiology studies ( 5 - 9 ) .…”

“…Thus, although ureteroscopy remains the gold standard, it can be technically challenging and is associated with significant rates of false-negative results, depending on the morphological characteristics of the lesion (4) . Several imageguided interventional techniques have been evaluated in Brazilian radiology studies (5)(6)(7)(8)(9) . Percutaneous biopsy can be performed in selected cases when the target segment of the ureter or renal pelvis cannot be accessed via ureteroscopy, is predominantly exophytic and non-endoluminal, or showed inconclusive results in previous samples.…”
