Dark Topics on Giant Retroperitoneal Liposarcoma: A Systematic Review of 157 Cases.

Background/objectives: Giant Retroperitoneal Liposarcomas (giant RPLs) represent a rare malignant disease of adulthood that does not yet have a univocal definition in the scientific literature. The symptoms may be late, depending on the position and the size reached. The weight may exceed 20 kg, and the diameter 25 cm.

R0 surgical resection of giant dedifferentiated retroperitoneal liposarcomas in the COVID era with and without nephrectomy: A case report.

Retroperitoneal sarcomas (RPSs) are rare findings that can grow into large masses without eliciting severe symptoms. At present, surgical resection is the only radical therapy, whenever it can be performed with the aim to achieve a complete removal of the tumor. The present report describes two consecutive cases of RPSs that resulted in dedifferentiated liposarcomas (DDLPSs) and these patients underwent R0 surgical resection with and without a nephron-sparing procedure.

COVID-19 and Living Donor Kidney Transplantation in Naples during the Pandemic.

Introduction: SARS-CoV-2 is a virus that causes a potentially deadly syndrome that affects especially the respiratory tract. Kidney-transplanted patients are immunosuppressed and more susceptible to viral infections. We have examined our transplantation activity to explore the future role of kidney transplantation from deceased and living donors in COVID-19 era.

Physical activity in elderly kidney transplant patients with multiple renal arteries.

Background: Kidney transplantation (KT) is the gold standard for treatment of patients with end-stage-renal disease. To expand the donor reserve, it is necessary to use marginal/suboptimal kidneys.

Methods: We retrospectively evaluated the short/long-term outcome of 34 KT elderly patients who received allografts with vascular abnormalities (MRA group), in comparison with 34 KT patients who received a kidney with a single renal artery (SRA group) pair-matched by age, length of time on dialysis, comorbidity and donor age.

Ethical Issues in the Use of Suboptimal Kidneys for Transplants: An Italian Point of View.

The shortage of organs leads to the need for utilizing suboptimal kidneys for transplantation. The distinction between optimal, marginal, and suboptimal kidneys leads surgeons to face not only technical problems but also ethical and legal issues related to clinical advantages offered by the transplant of a nonstandard kidney and the acquisition of consent. Between 1999 and 2015, we performed 658 transplants, 49 (7.
