Intracaval misplacement of a double-J ureteral stent.

Double-J ureteral stent (DJUS) is an important therapeutic tool in endourology. There are well-known frequent complications associated with DJUS placement such as distal and proximal migration within the urinary tract. However, perforation and stent misplacement are uncommon but serious complications of this technique.

Prostate Cancer in Renal Transplant Recipients: Diagnosis and Treatment.

Background: We currently know that prostate cancer (Pca) risk is reduced in patients undergoing kidney transplantation. However, its impact and treatment are not widely studied.

Methods: This was a retrospective study of male patients submitted to kidney transplantation in our center from 1980 to 2016 evaluating incidence, treatment, and follow-up of Pca in our population.

Small kidneys for large recipients: does size matter in renal transplantation?

Background: Imbalance between transplanted renal mass and the metabolic demands of the recipient has been identified as a predictor of renal graft function. Multiple factors have been used to test this influence, but none of them is consensually accepted. The aim of this study is to evaluate the influence of the imbalance between transplanted renal mass and the metabolic needs of the recipient by analyzing the relationship between the ratio of the weight of the renal graft and the body weight of the recipient (Kw/Rw) on transplantation outcomes.

Kidney retransplantation: removal or persistence of the previous failed allograft?

A significant percentage of patients with failed renal graft are candidates for retransplantation. The outcomes of retransplantation are poorer than those of primary transplantation and sensitization is documented to be a major reason. The management of a failed allograft that is not immediately symptomatic is still very controversial.
