Partial nephrectomy, using open surgery or laparoscopy, is a standard surgical approach to treat renal disorders. The objective of this study was to compare and evaluate the feasibility and safety of laparoscopic partial nephrectomy using figure eight ligation technique. Mixed-breed dogs were randomly dedicated for partial nephrectomy using laparoscopy (n=6) and open surgery (n=6). During 30 days after operation, clinical, hematological and ultrasonographic findings, intra- and post-operative complications, operation and ischemia times, urine analysis and incision length were recorded...

OBJECTIVE: It was reported that a metabolic syndrome affected the remaining renal function after living donor nephrectomy. However, the measurement of waist circumference is unclear because it cannot distinguish between visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT). We investigate the clinical correlation between body adipose tissue and renal function recovery after living donor nephrectomy. METHODS: From July 2013 to February 2015, 75 living kidney donors were enrolled...

BACKGROUND: Living pancreas transplantation plays an important role in the treatment of patients with severe type 1 diabetes. However, pancreatectomy is very invasive for the donor, and less-invasive surgical procedures are needed. Although some reports have described hand-assisted laparoscopic surgery for distal pancreatectomy in living-donor operations, less-invasive laparoscopy-assisted (LA) procedures are expected to increase the donor pool. We herein report the outcomes of four cases of LA spleen-preserving distal pancreatectomy (Warshaw technique [WT]) in living pancreas donors...

REVIEW
Colin J McCarthy, Debra A Gervais
Renal cell carcinoma is a relatively common tumor, with an estimated 63,000 new cases being diagnosed in the United States in 2016. Surgery, be it with partial or total nephrectomy, is considered the mainstay of treatment for many patients. However, those patients with small renal masses, typically less than 3 to 4 cm in size who are deemed unsuitable for surgery, may be suitable for percutaneous thermal ablation. We review the various treatment modalities, including radiofrequency ablation, microwave ablation, and cryoablation; discuss the advantages and disadvantages of each method; and review the latest data concerning the performance of the various ablative modalities compared with each other, and compared with surgery...

Metanephric stromal tumor (MST) of the kidney, a rare benign pediatric neoplasm recognized for less than 20 years, is not widely known. The authors describe a case of MST with rare squamous epithelium in a 14-month-old female. A renal mass was discovered during her fetal period. After her birth, computerized tomography revealed that the mass was localized in the inferior pole of her left kidney. She then underwent nephrectomy. The tumor was an unencapsulated but well-defined mass with a white, solid and firm cut surface and had dimensions of 4cm×3...

PURPOSE: We sought to determine whether median household income (MHI) independently predicts surgical approach (partial vs. radical nephrectomy) and survival in patients with renal cell carcinoma. METHODS: The U.S. Surveillance Epidemiology and End Results Database (1988-2011) was queried to examine kidney cancer cases and linked to the Area Health Resources File. We correlated surgical approach and survival, both overall and cancer-specific, with tumor stage, age, race, sex, and income data...

OBJECTIVE: This study evaluated whether more effective perioperative analgesia can be part of a multimodal approach to minimizing morbidity and improving postoperative management after the open surgical approaches frequently used in the treatment of renal cell carcinoma (RCC). The aim of the study was to determine whether spinal anesthesia with clonidine can enhance postoperative analgesia, speed up mobilization and reduce the length of hospital stay (LOS). MATERIALS AND METHODS: Between 2012 and 2015, 135 patients with RCC were randomized, in addition to general anesthesia, to receive either spinal analgesia with clonidine or epidural analgesia, stratified to surgical technique...

Partial nephrectomy is the gold standard for the renal tumours less than 7 to 10cm whenever feasible in order to preserve renal function. The extension of nephron-sparing surgery using a mini-invasive approach is possible by robotic surgery. Radical nephrectomy is mandatory in the other situations and especially in case of locally advanced renal carcinoma. The place of cytoreductive nephrectomy in metastatic renal cell carcinoma is the purpose of the CARMENA trial. Tyrosine kinase inhibitors are currently the first line treatment; but in the near future new immunotherapy by checkpoints molecules could crucially change the treatment of metastatic renal cell carcinoma...

INTRODUCTION: To determine tumour, patient, and provider factors associated with cytoreductive nephrectomy (CN) use and to identify those factors that predicted short-term and long-term surgical outcomes. METHODS: We performed a retrospective review (1998-2011) of the National Cancer Database, a U.S. population-based oncology outcomes database. The review included 36 549 patients with metastatic renal cell carcinoma (mRCC). We assessed predictors of CN use, length of stay (LOS), 30-day readmission, and 30-day mortality using multivariable logistic regression...

Children are at higher risk of renal injury from blunt trauma than adults due to a variety of anatomic factors such as decreased perirenal fat, weaker abdominal muscles, and a less ossified thoracic cage. Non-operative management is gaining in popularity for even major injuries, although there are no universally accepted guidelines. We present a retrospective review of pediatric major blunt renal injuries (grade 3 or higher) at a children's hospital in Hawai'i over a 5-year period. Medical records were examined between January 2009 and September 2014 from Kapi'olani Medical Center for Women and Children in Honolulu, Hawai'i...

INTRODUCTION: The aim of the study was to determine whether perioperative complications and postoperative outcomes varied with the indication of partial nephrectomy (PN). MATERIALS AND METHODS: We reviewed data of 184 consecutive PN for suspected renal cell carcinoma operated between January 2004 and December 2013. Complications using the Clavien-Dindo classification were compared between surgeries for absolute indications (chronic renal failure, bilateral tumors, or solitary kidney), those for relative indications (comorbid illnesses with the potential to affect renal function) and elective indications (patients without risk factors)...

Radical nephrectomy is associated with a progressive decline in renal function. Clinical parameters in post-nephrectomy insufficiency were described but the impact of histopathologic vascular findings in the non-neoplastic kidney of nephrectomy specimen, has been poorly studied. Our aim was to evaluate whether the severity of atherosclerosis in non-neoplastic renal tissue predicts the evolution of glomerular filtration rate in patients undergoing total nephrectomy. Thirty-one non-donor patients with unilateral radical nephrectomy were included...
