Nrf2 Signaling in Renal Cell Carcinoma: A Potential Candidate for the Development of Novel Therapeutic Strategies.

Renal cell carcinoma (RCC) is the most common type of kidney cancer arising from renal tubular epithelial cells and is characterized by a high aggressive behavior and invasiveness that lead to poor prognosis and high mortality rate. Diagnosis of RCC is generally incidental and occurs when the stage is advanced and the disease is already metastatic. The management of RCC is further complicated by an intrinsic resistance of this malignancy to chemotherapy and radiotherapy, which aggravates the prognosis.

Comparison of Perioperative, Functional, and Oncologic Outcomes of Open vs. Robot-Assisted Off-Clamp Partial Nephrectomy: A Propensity Scored Match Analysis.

Off-clamp partial nephrectomy represents one of the latest developments in nephron-sparing surgery, with the goal of preserving renal function and reducing ischemia time. The aim of this study was to evaluate and compare the functional, oncologic, and perioperative outcomes between off-clamp robot-assisted partial nephrectomy (off-C RAPN) and off-clamp open partial nephrectomy (off-C OPN) through a propensity score-matched (PSM) analysis. A 1:1 PSM analysis was used to balance variables potentially affecting postoperative outcomes.

Current Evidence on Surgical Management for Benign Prostatic Hyperplasia in Renal Transplant Recipients: A Systematic Review.

Patients who have undergone renal transplant may have a concomitant benign prostatic hyperplasia (BPH), a condition that can potentially hinder the recovery of the renal graft and necessitate surgical intervention. However, endoscopic treatment of BPH should be performed carefully because of the associated perioperative risks. We aimed to systematically assess the factors affecting surgical indications and perioperative outcomes of BPH surgical treatment in renal transplantation (RT) recipients.

Clinical progression of megacalycosis in a girl with a solitary kidney: The lesson learned.

Introduction: Megacalycosis is a rare disorder related to congenital underdevelopment of the renal papilla or structural defect of the renal calyces. Megacalycosis has a wide spectrum of clinical presentations ranging from simple variants without any significance on renal function to severe complications. Any prevention strategy is recommended yet since megacalycosis is mostly asymptomatic and usually discovered either accidentally or as result of its complications.

Recent Advances in the Management of Clear Cell Renal Cell Carcinoma: Novel Biomarkers and Targeted Therapies.

Renal cell carcinoma (RCC) belongs to a heterogenous cancer group arising from renal tubular epithelial cells. Among RCC subtypes, clear cell renal cell carcinoma (ccRCC) is the most common variant, characterized by high aggressiveness, invasiveness and metastatic potential, features that lead to poor prognosis and high mortality rate. In addition, diagnosis of kidney cancer is incidental in the majority of cases, and this results in a late diagnosis, when the stage of the disease is advanced and the tumor has already metastasized.

Improving clinical diagnostic accuracy and management of False penile fractures characterizing typical clinical presentation: a systematic review and meta-analysis.

Purpose: False penile fractures (FPF) represent a rare sexual emergency characterized by blunt trauma of penis in the absence of albuginea's injury, with or without lesion of dorsal penile vein. Their presentation is often indistinguishable from true penile fractures (TPF). This overlapping of clinical presentation, and lack of knowledge about FPF, can lead surgeons often to proceed directly to surgical exploration without further examinations.
