Objective: We present nephron sparing renal surgery as a therapeutic option for the conservative treatment of renal cancer by reporting one case of de novo renal cell carcinoma (RCC) presenting in a functioning renal graft.
Methods/results: We describe one case of de novo RCC presenting in a functioning renal graft 51 months after transplantation. Tumorectomy was carried out with a margin of normal parenchyma and the base was free of tumor. Definitive pathologic study showed type I papillary renal cell carcinoma, Fuhrman grade 2, pathological stage I with free margins. There were not post operative complications and immunosuppression therapy was not modified. After almost three years of follow-up there is no evidence of tumor recurrence and an adequate renal function.
Conclusions: Renal graft RCC is rare. Conservative surgery in selected patients may be a safe and effective technique when the tumor appears in a functioning graft, because it offers good oncological control and preserves renal function, avoiding transplant nephrectomy and the need of haemodialysis.

Objective: Systemic lupus erythematosus (SLE) is a heterogeneous disease which manifests as different subphenotypes. Distinct subphenotypes, such as lupus nephritis (LN), have been associated with increased genetic risk, but prior studies have been limited by cross-sectional and imprecisely subphenotyped cohorts. This study investigated the genetic basis for LN using a longitudinal cohort of distinctly subphenotyped patients.

Background: Some studies suggest that balanced solutions may improve outcomes in critical care patients. However, in patients with traumatic brain injury (TBI) existing data indicate that normal saline may be preferred. We hypothesized that mortality in critically ill patients with and without TBI would differ with the use of balanced salt solutions versus normal saline.

Dynamic positron emission tomography (PET) can be used to non-invasively estimate the blood flow of different organs via compartmental modeling. Out of different PET tracers, water labeled with the radioactive O isotope of oxygen (half-life of 2.04 min) is freely diffusable, and therefore, very well-suited for blood flow quantification.

A 54-year-old man who had been on the kidney donor register for 32 years received a kidney from a 9-year-old boy who had died of fulminant myocarditis. The post-operative course was poor, and hemodialysis was still needed after surgery. A kidney biopsy one hour after surgery showed a neutrophil-predominant inflammatory cell infiltrate localized to the peritubular capillaries (PTC) and acute tubular necrosis of the proximal tubule.

Objectives: To evaluate the at-risk organs that require protection during percutaneous cryoablation (PCA) of renal tumours and the correlation with patient and target lesion characteristics, type of protective measure used and postoperative outcomes.
Materials And Methods: Single-centre retrospective review of patients with renal tumours who underwent PCA between 2008 and 2020. Final analysis included 374 tumours.
