Authors: M. Calandri, P. Haslam and L. Monfardini

Reviewers: D. Castiglione, D. Filippiadis, A. Ierardi, R. Iezzi, T. Kratimenos, D. Rossi and R. Uberoi

This course corresponds to chapters 2.1.9 Core procedures in interventional radiology, 2.2.3.1 Pelvicalyceal and ureteric obstruction and 2.2.3.4 Genito-urinary interventions in the European Curriculum and Syllabus for Interventional Radiology.

Abstract

The purpose of this module is to introduce IRs to basic and advanced techniques for adequate management of pelvicalyceal and ureteric obstruction with a specific focus on nephrostomy and stent insertion. Anatomical and pathophysiological aspects are covered as well as indications and contraindications. The module also covers the most relevant technical aspects of nephrostomy insertion, anterograde stent insertion for native bladder, and urinary diversions. Rendezvous procedures, ureteral stricture intervention, and renal stone disease are also less extensively discussed, mostly with pictorial cases. Later, the module discusses materials and devices, focusing especially on those used in nephrostomy and ureteral stent insertion.

Some controversies are debated, such as the role of IR versus that of urology. Complications and post-procedural management suggestions are listed with some practical advice for clinical practice.

The learning module is expected to give a complete overview about the principal urinary interventional procedures with a special focus on technical and clinical aspects.
