“…Especially MWA seems to be more eff ective due to higher temperatures, larger tumor ablation volumes and faster ablation times [13]. Major complication rate requiring treatment is reported lower than 5%, while procedure-related mortality is considered as relative rare, so that these methods can be characterized as safe [5][6][7][8][9][10][11][14][15][16].…”

We report the case of a 71-year-old female patient with previous history of rectal cancer. The primary cancer was resected and three cycles of chemotherapy were completed. Excision of metastatic lesions was also performed from the left liver lobe. Due to the presence of new liver lesions on the right lobe, intra-operative microwave ablation was decided. Three hours post ablation the patient bled massively and angiography revealed extravasation from a peripheral branch of the right hepatic artery. Successful embolization was performed; however, the patient died 5 days later on liver failure. We would like to present the case and discuss the technical options and the key points to help avoiding similar complications in the future.

Ureteric complications following renal transplantation are well known to cause significant morbidity and compromised graft survival. The necrosis of a major part of the ureter could be a highly detrimental situation, and hardly solvable complication, that poses great challenges. Herein we are presenting a case report to introduce a possible surgical solution following repeated ineffective radiological interventions, in a patient with ureteric necrosis that appeared 3 months after cadaveric kidney transplantation. We transplanted the right kidney to the right iliac fossa performing end-to-side vascular anastomoses and end-to-side uretero-ureterostomy. His clinical course was uneventful during 3 months, when he presented a mild borderline acute cellular rejection together with dilatation of the pyelon. Percutaneous nephrostomy was performed by interventional radiologist. During further radiologic interventions the stenosis was not permeable. We finally made up our minds for surgical solution. We found a totally necrotized graftureter. During a second operation we performed a right nephrectomy, transsecting the pyelon. After mobilization of the transplanted kidney approaching and identifying the pyelon, a large pyelopyelar anastomosis was performed with stenting. The postoperative follow-up showed excellent urine flow from the kidney to the bladder, then the TRD was removed. Surgery had to be considered only if minimally invasive procedures are infeasible or ineffective. A regimen of reconstructive methods are well-known, but all cases have to be evaluated individually. If the native kidneys can be removed, their pyelons and entire ureters should be used for reconstruction.
