The article presents results of examination and treatment of 14 patients aged from 46 through 79 years with chronic occlusion of one of the renal arteries in each of them and subocclusion of the contralateral renal artery in 13 patients due to atherosclerosis. At first percutaneous intraluminal angioplasty and stenting were performed in 13 out of 14 patients with stenosis of the renal artery. Then at once only percutaneous intraluminal angioplasty of the occlused renal artery was performed in 10 out of 14 patients and within 36 hours on average the implantation of stents in case of patency of the renal artery proper and its branches, according to the findings of control angiography, in these arteries with the optimal result. The percutaneous intraluminal angioplasty and stenting are relatively safe and effective methods of reestablishment of patency of the renal arteries after their chronic occlusion.

Approximately 5-10% of patients with hypertension have secondary hypertension. We describe a case of secondary hypertension from bilateral renal artery stenosis (RAS): "Pickering syndrome." This is a case of hypertension secondary to bilateral RAS which provides an opportunity to review secondary hypertension with a specific focus on RAS, in terms of when to consider work up, causes of secondary hypertension, diagnostic testing, and treatment.

Background And Aim: Coronary artery bypass grafting (CABG) is a key treatment for coronary artery disease, but accurately predicting patient survival after the procedure presents significant challenges. This study aimed to systematically review articles using machine learning techniques to predict patient survival rates and identify factors affecting these rates after CABG surgery.
Methods: From January 1, 2015, to January 20, 2024, a comprehensive literature search was conducted across PubMed, Scopus, IEEE Xplore, and Web of Science.

Percutaneous vertebroplasty (PVP) is a widely utilized minimally invasive technique originally developed for the treatment of vertebral compression fractures. It has since expanded to treat osteoporotic vertebral compression fractures, pathologic vertebral fractures resulting from primary or secondary spinal tumors, and traumatic spinal fractures. Despite its benefits, PVP is associated with significant complications, the most common of which is bone cement leakage.

The increasing age of patients with end-stage renal disease raises the issue of hostile arterial access for transplantation, with technical difficulties associated with clamping and suturing the iliac artery. Some of these patients - who theoretically represent those who would benefit the most from transplantation in terms of mortality - are contraindicated because of anatomical and medical issues. In this context, a specific endovascular device called EndoPreKiT (Endovascular Preparation for Kidney Transplantation) has been designed, enabling arterial access for transplantation via a mini-invasive procedure.

Objectives: To assess the feasibility of trial recruitment and confirm that retroperitoneal robotic partial nephrectomy (RRPN) has the same oncological efficacy as transperitoneal robotic partial nephrectomy (TRPN), with time advantages and less peri-operative morbidity, in a randomised controlled trial (RCT).
Patients And Methods: The study was designed as a single-centre, open-label, feasibility RCT. Patients with suspected localised renal cell carcinoma referred for robotic partial nephrectomy were randomised in a 1:1 ratio to receive either TRPN or RRPN.
