Purpose: Percutaneous renal artery embolisation has been introduced as an alternative to nephrectomy in patients with non-functioning allograft and Graft Intolerance Syndrome (GIS). The symptoms resulting from GIS include fever, local pain, hypertension and haematuria.
Materials And Methods: From April to October 2003, five patients were treated using this technique. The intraparenchymal renal arteries were embolized by injection of calibrated tris-acryl gelatin microspheres of increasing size (from 100-300 to 700-900 microns) and occlusion was completed by the insertion of 5mm to 8mm steel coils into the renal artery.
Results: The procedure was well tolerated in all cases and no major complications occurred. In 3 patients GIS-related symptoms disappeared immediately. One patient required a second embolisation due to collateral circulation arising from a lumbar artery with resolution of symptoms. In the last case, the patient underwent nephrectomy because of septic fever.
Conclusions: On the basis of our preliminary experience we believe that, in selected patients, percutaneous renal artery embolisation is an effective, repeatable and minimally invasive alternative to nephrectomy with no significant serious complications.

Simultaneous pancreas-kidney (SPK) transplantation is a recognized treatment for patients with insulin-dependent diabetes and advanced chronic kidney disease or end-stage renal disease (ESRD), offering significant survival benefits. However, it is associated with a higher risk of venous thrombosis, which can jeopardize the survival of the pancreaticoduodenal graft. This case report describes a patient with type 2 diabetes, hypertension, and ESRD who developed acute, occlusive deep vein thrombosis (DVT) involving the right common femoral, profunda femoral, and greater saphenous veins on postoperative day 1 (POD1) following a deceased donor SPK transplant, despite systemic prophylactic anticoagulation.

Background: Managing lower pole renal stones presents clinical challenges influenced by various factors such as stone size, location, and density. This study aims to assess the efficacy, safety, and stone-free rates of Flexible Ureteroscopy (FURS), Extracorporeal Shock Wave Lithotripsy (ESWL), and Mini Percutaneous Nephrolithotomy (Mini PCNL) for treating lower pole renal hard stones (< 2 cm).
Methods: A prospective single-centre comparative study was conducted on 414 adult patients with primary lower pole renal hard stones.

Background: Lower calyceal anatomy makes the stone clearance a difficult task across all treatment formats. Improvement in optics and miniaturization of instruments have offered an effective and safer alternative to percutaneous nephrolithotomy (PCNL). The study was conducted to compare the efficacy and complications associated with mini-PCNL vs standard-PCNL.

Objective: This study aims to identify the risk factors for systemic inflammatory response syndrome (SIRS) after minimally invasive percutaneous nephrolithotomy (PCNL) with a controlled irrigation pressure and to find which patients undergoing PCNL are likely to develop SIRS under the pressure-controlled condition.
Methods: A total of 303 consecutive patients who underwent first-stage PCNL in our institute between July 2016 and June 2018 were retrospectively reviewed. All the procedures were performed with an 18 F tract using an irrigation pump setting the irrigation fluid pressure at 110 mmHg and the flow rate of irrigation at 0.

Article Synopsis
- The study investigated how different treatments (balloon angioplasty vs. drug-coated balloons) affect the changes in blood vessel tissues following arteriovenous fistula stenosis in pigs with chronic kidney disease.
- Significant differences in tissue composition were observed, with drug-coated balloons leading to lower neointimal growth and higher endothelial cell counts compared to standard angioplasty.
- The findings suggest that using drug-coated balloons may improve vessel healing and reduce complications over time, as shown by varied immune cell responses and tissue growth patterns.
