The ureteric "rendezvous" procedure is an interventional procedure involving both uro-radiological and cystoscopic techniques to manage complex ureteric stenoses or fistulae. We present a case in which this procedure was utilised, with an unusual intra-procedural finding. Macroscopic visualisation of lipids within the urinary tract is an unusual finding at CT, and rarely seen at cystoscopy. The aetiology of lipiduria is varied; it may indicate the presence of unrecognised pathology, occur as a sequelae of trauma, or arise secondary to intervention. Understanding the patient's history is vital to determining the likely aetiology and significance of such a finding.

Background And Aims: Difficult biliary cannulation (DBC) is a marker for prolonged procedure time and increased adverse event rate (AER) during endoscopic retrograde cholangiopancreatography (ERCP). We previously showed that EUS-guided rendezvous procedure (EUS-RV) had a higher single session success rate than precut papillotomy (PcP) in DBC patients. The present randomized study aims at comparing the technical success and AER between the two approaches.

Background: Advancing the retrograde microcatheter (MC) into the antegrade guide catheter during retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI) can be challenging or impossible, preventing guidewire externalization.

Objectives: To detail and evaluate all the techniques focused on wiring to achieve intubation of the distal tip of a microcatheter, balloon, or stent with an antegrade or retrograde guidewire, aiming to reduce complications by minimizing tension on fragile collaterals during externalization and enabling rapid antegrade conversion in various clinical scenarios.

Methods: We describe the two main techniques, tip-in and rendezvous, and their derivatives such a facilitated tip-in, manual MC-tip modification, tip-in the balloon, tip-in the stent, deep dive rendezvous, catch-it and antegrade microcatheter probing.

Purpose: To demonstrate the Modified Balloon Nose Cone Technique to avoid passage of the aortic valve in endovascular branched arch repair.

Technique: The technique is demonstrated in a 54-year-old patient after previous open repair of the ascending aorta and mechanical aortic valve replacement due to type A aortic dissection. The delivery system of a custom-made stent-graft with 3 inner branches was modified by subtotally sawing off its nose cone.

Introduction: Transurethral resection is the main method for diagnosing and staging bladder cancer, which allows to determine treatment tactics. Tumors located in the area of the ureteric orifice is an important clinical problem.

Aim: To describe our experience in the treatment of ureteral obliterations after transurethral resection of the bladder tumors.
