Open partial nephrectomy in solitary kidney with multiple renal cell carcinoma: a case report / 中国医学科学杂志(英文版)

Renal cell carcinoma (RCC) in a solitary kidney presents a unique clinical challenge to urological surgeons. Partial nephrectomy (PN) or nephron-sparing surgery in this condition provides good oncological and renal functional outcomes with an acceptable complication rate. Long-term renal function remains stable in most patients with solitary kidneys after a reduction of more than 50% in renal mass.PN is a surgical procedure reserved for patients with a tumor in a solitary kidney, bilateral renal tumors, or renal function impairment. The challenge of preserving renal parenchyma is significantly complicated with the discovery of multiple masses in a solitary kidney because any subsequent complications may result in a significant decline in quality of life. Particularly in the case of postoperative renal failure, dialysis becomes necessary.

Safety and effectiveness of percutaneous embolization for late failed renal allograft in patients with graft intolerance syndrome / 中国医学科学院学报

<p><b>OBJECTIVE</b>To investigate the clinical safety and effectiveness of percutaneous embolization in treating the late failed renal allograft in patients with graft intolerance syndrome (GIS).</p><p><b>METHODS</b>Transcatheter embolization of renal graft artery was performed in 18 patients with late graft dysfunction and GIS. The subsequent complications, postoperative symptom remission rate, and prognosis were assessed.</p><p><b>RESULTS</b>GIS was relieved in 15 patients (83.3%), of which 6 patients (33.3%) had severer fever and pain in the area of renal graft after embolization, which lasted for a mean of 3.5 days (range: 2-5 days). GIS persisted for more than 2 weeks in 3 patients (16.7%), who ultimately underwent surgical removal of grafts. No severe embolism-associated complications were noted.</p><p><b>CONCLUSION</b>Percutaneous embolization can effectively avoid surgical graft removal in patients with late renal allograft failure, and therefore can be used as a safe and effective treatment for the late failed renal allograft combined with GIS.</p>
