A case report of robot-assisted radical nephrectomy and inferior vena cava thrombectomy in a patient with renal cell carcinoma after pembrolizumab and axitinib combination therapy.

Background: Robot-assisted surgery is widely performed for renal cell carcinoma (RCC) with inferior vena cava (IVC) tumor thrombi. Although many chemotherapeutic options are available for the treatment of unresectable RCC, there are very few reports on robot-assisted radical nephrectomy (RARN) with inferior vena cava thrombectomy (IVCT) after presurgical treatment with immune checkpoint inhibitors and tyrosine kinase inhibitors. We believe that pre-surgical treatment can provide minimally invasive surgical benefits to high-risk patients during the perioperative period.

CD21 B Cells Could Be a Potential Predictor of Immune-Related Adverse Events in Renal Cell Carcinoma.

Immune checkpoint inhibitor (ICI) therapy increases the risk of immune-related adverse events (irAEs). In particular, combination checkpoint blockade (CCB) targeting inhibitory CTLA-4 and PD-1 receptors could lead to irAEs at a higher rate than ICI monotherapy. Management of irAEs is important while using ICIs.

Case Report: Heparin-Induced Thrombocytopenia Treated With Plasmapheresis Before Living-Donor Kidney Transplantation.

Background: Heparin-induced thrombocytopenia (HIT) is a serious adverse effect of heparin. Additionally, although heparin can affect kidney transplantation, there only have been a few reports on this condition. Here, we report a case wherein surgery was safely performed with preoperative plasmapheresis in a patient with HIT.

Extended robot-assisted laparoscopic prostatectomy and extended pelvic lymph node dissection as a monotherapy in patients with very high-risk prostate cancer Patients.

Background: Patients with very-high-risk prostate cancer (VHRPCa) have earlier biochemical recurrences (BCRs) and higher mortality rates. It remains unknown whether extended robot-assisted laparoscopic prostatectomy (eRALP) without neoadjuvant or adjuvant therapy can improve the outcomes of VHRPCa patients. We aimed to determine the feasibility and efficacy of eRALP as a form of monotherapy for VHRPCa.

Sequential immune-targeted surgical therapy resulted in disease-free survival in a case with advanced renal cell carcinoma.

Background: Currently, immunotherapy is indicated for patients with metastatic RCC or unresectable RCC, but there is no indication for immunotherapy in the neoadjuvant setting. We report a case in which the combined use of nivolumab and ipilimumab and sequential TKI therapy enabled surgical treatment.

Case Presentation: A 71-year-old female was diagnosed with a metastatic clear-cell renal cell carcinoma with a level IV tumor thrombus.

Predictors of Hypotension after Adrenalectomy for Pheochromocytoma.

The management of blood pressure is a significant concern for surgeons and anesthesiologists performing adrenalectomy for pheochromocytoma. We evaluated clinical factors in pheochromocytoma patients to identify the predictors of postoperative hypotension. The medical records of patients who underwent adrenalectomy for pheochromocytoma between 2001 and 2017 were retrospectively reviewed and clinical and biochemical data were evaluated.

Venous reconstruction using a Y-shaped saphenous vein in kidney transplantation: A report of three cases.

Introduction: Transplantation, especially, of the right kidney may be difficult to properly choose the main drainage vein due to abundance of renal veins with the thin wall and the small diameter. Therefore, we report three cases, wherein anastomosis-related complications may be avoided by using a reconstructed Y-shaped major saphenous vein graft.

Case Presentation: The first case was a case of congestion when anastomosed with a trifurcated renal vein which ligated branch.

A low RENAL Nephrometry Score can avoid the need for the intraoperative insertion of a ureteral catheter in robot-assisted partial nephrectomy.

Background: Intraoperative urinary collecting system entry (CSE) in robot-assisted partial nephrectomy (RAPN) may cause postoperative urinary leakage and extend the hospitalization. Therefore, identifying and firmly closing the entry sites are important for preventing postoperative urine leakage. In RAPN cases expected to require CSE, we insert a ureteral catheter and inject dye into the renal pelvis to identify the entry sites.

Feasibility of Laparoscopic Radical Cystectomy in Elderly Patients: A Comparative Analysis of Clinical Outcomes in a Single Institution.

Laparoscopic radical cystectomy (LRC) is a standard surgical treatment for muscle-invasive bladder cancer and high-risk non-muscle-invasive bladder cancer. LRC is a less invasive modality than conventional open surgery. Therefore, even elderly patients with invasive bladder cancer may be candidates for LRC.

New classification of hydronephrosis on 18F-FDG-PET/CT predicts post-operative renal function and muscle-invasive disease in patients with upper urinary tract urothelial carcinoma.

Objectives: To evaluate the value of a classification of hydronephrosis on 18F-flurodeoxyglucose (FDG)-PET/CT in predicting post-operative renal function and pathological outcomes among patients with upper urinary tract urothelial carcinoma.

Methods: We retrospectively reviewed 71 patients treated with nephroureterectomy (NU) for upper urinary tract urothelial carcinoma after FDG-PET/CT between 2010 and 2016. Eight patients treated with ureteral stent or nephrostomy at the time of FDG-PET/CT were excluded.

Silencing of inhibits growth of gemcitabine-resistant bladder cancer cells.

Combined gemcitabine and cisplatin (GC) treatment is a first line chemotherapy for bladder cancer. However, acquired resistance to GC has been a major problem. To address the mechanism of gemcitabine resistance, and to identify potential biomarkers or target proteins for its therapy, we aimed to identify candidate proteins associated with gemcitabine resistance using proteomic analysis.

Primary adrenal leiomyosarcoma with lymph node metastasis: a case report.

Background: Leiomyosarcomas typically originate in smooth muscle cell. Leiomyosarcoma potentially arising from the adrenal gland is an extremely rare mesenchymal tumors associated with delayed diagnosis and poor prognosis.

Case Presentation: A 34-year-old man visited our department complaining of right hypochondriac pain.

Low-Dose Docetaxel Combined with Dexamethasone Is Feasible for Patients with Castration-Resistant Prostate Cancer.

Aim: Docetaxel-based chemotherapy against castration-resistant prostate cancer (CRPC) has recently been shown to be effective and tolerable. The objective of this study was to retrospectively evaluate the efficacy and toxicity of low-dose docetaxel in combination with dexamethasone.

Methods: Thirty-seven CRPC patients were administered a treatment regimen consisting of 50 mg/m2 docetaxel once every 3-4 weeks and 1 mg dexamethasone daily at our institution, between November 2004 and April 2014.

Long‑term exposure to leptin enhances the growth of prostate cancer cells.

Obesity correlates with an increased risk of developing prostate cancer (PCa) and leptin plays an important role in PCa progression. Since leptin is produced by adipocytes, the serum leptin level is higher in obese than in non-obese individuals. However, the effects of leptin remain controversial and unclear.

[Clinicopathologic characteristics and prognosis of patients with adrenocortical carcinoma].

Purpose: Adrenocortical carcinoma (ACC) is a rare condition associated with poor prognosis. This study aimed to evaluate the clinicopathologic characteristics and prognosis of 7 patients with ACC.

Patients And Methods: The clinicopathologic characteristics, treatment, and survival of 7 patients with pathologically confirmed ACC treated at our institution between January 2002 and December 2012 were retrospectively examined.
