INTRODUCTION: Recently, the use of indocyanine green (ICG) with near infrared fluorescence (NIRF) imaging has emerged as an alternative technique for the real-time delineation of resection margins during partial nephrectomy (PN). We aimed to assess the feasibility of using NIRF imaging with ICG during laparoscopic partial nephrectomy (LPN) to delineate the margin between normal renal parenchyma and renal cortical tumors. MATERIALS AND METHODS: A retrospective comparison of real-time tumor margin identification and operative outcomes was conducted for 83 patients who underwent LPN with NIRF imaging (IMAGE1 system) and 74 patients who did not...

A 71-year-old man with left flank pain was referred to our hospital. Computed tomography (CT) revealed a left renal tumor, left renal pelvic wall thickening, bilateral adrenal gland swelling, multiple pulmonary nodules, and a bone metastatic tumor. Further, positron emission tomography/CT revealed increased 18F fluorodeoxyglucose uptake in the left renal tumor, multiple pulmonary nodules, and bone metastatic tumor. Accordingly, we performed biopsies of the thickening of the left renal pelvic wall and bone metastatic tumor, and histological examinations revealed an unknown type carcinoma and bone metastasis from clear cell carcinoma...

A 69-year-old woman was admitted to the previous hospital because of a right adrenal tumor detected by a medical checkup. Although the tumor was diagnosed as non-functional adrenal adenoma, abdominal computed tomography (CT) revealed a left renal mass which was suspected to be renal cell carcinoma. Chest CT seeking for metastatic lesions revealed lung cancer of the left lung. First, laparoscopic radical nephrectomy was performed. After the surgery, 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) CT performed for staging of the lung cancer demonstrated FDG uptake to the left lung mass, the heart, the right adrenal mass and perirenal regions of the right kidney...

Background: Postoperative pain management is important for the early recovery of the living donor patient. Patient-controlled opioid analgesia, epidural analgesia, or a combination of both is the preferred pain management after abdominal surgery although these approaches have serious side effects. The transversus abdominis plane (TAP) block has been increasingly used for postoperative pain management and the addition of dexamethasone to local anesthetic can prolong the duration of action...

INTRODUCTION: Laparoscopic radical nephrectomy is the gold standard for treatment of renal cell carcinoma. However, previous abdominal surgery is generally regarded as a contraindication to the laparoscopic approach because it causes intraperitoneal adhesions, which are thought to interfere with subsequent laparoscopic procedures inside the abdominal cavity. Few studies have examined the influence of prior surgery on laparoscopic nephrectomy. Therefore, the aim of this study was to evaluate the impact of previous laparotomy on laparoscopic nephrectomy...

INTRODUCTION: Failure of kidney migration during embryonic life results in an ectopic kidney, with an incidence varying from 1 in 500 to 1 in 1200. Pelvic kidney can be a rare cause of recurrent urinary tract infection (UTI), warranting nephrectomy in some cases. MATERIAL AND METHODS: A 7-year-old girl with a history of recurrent UTIs and vaginal discharge was diagnosed with a dysplastic afunctional ectopic kidney located in the pelvis, with ureter draining into the cervix or vaginal wall...

OBJECTIVE: To investigate whether patients requiring dialysis are a higher risk surgical population and would experience more peri-operative adverse events even when undergoing a perceived less invasive operation as a laparoscopic radical nephrectomy (LRN). LRN is generally a well-tolerated surgical procedure with minimal morbidity and mortality. Prior to transplantation, dialysis patients will often have to undergo a LRN to remove a native kidney with a suspicious mass. MATERIALS AND METHODS: Patients in the American College of Surgeons National Surgical Quality Improvement Program who underwent a laparoscopic radical nephrectomy between 2011 and 2016 were included...

The sympathetic nervous system was known to play an important role in resistant hypertension. Surgical sympathectomy for renal sympathetic nerve removal were performed since the 1930s. Although effective, it had many serious side effects and complications due to non-selective property. Recently, catheter based RDN system using radiofrequency (RF) ablation was developed and considered promising, however, it failed in sham controlled trial. Therefore, there are needs for safe and effective RDN strategies considering the anatomical structure of the renal arteries and sympathetic nerves...

Introduction: Endophytic renal tumors that are completely intraparenchymal pose several challenges to surgeons, including in intraoperative tumor identification. Image-guided hook wires, which are now used in surgery, particularly in spinal surgery, thoracoscopic surgery, and breast surgery, allow for the precise localization of tumor sites. The hook wire facilitated the localization of the lesion and avoided cutting into the lesion directly. Case Presentation: A 55-year-old woman was referred to our hospital due to an incidentally discovered 16-mm intracortical right renal mass in the anterior medial position...

We present an unusual case of a rare ossifying renal tumor of infancy. A 6-month-old male initially presented with gross hematuria and without any palpable abdominal mass. Renal ultrasound and MRI showed a right lower pole, calcified, endophytic renal mass. Laparoscopic radical nephrectomy was performed without complications. Pathology demonstrated an ossifying renal tumor of infancy. We report this case, in addition to a review of the literature for similar cases, to highlight a rare renal tumor in infancy that can be managed laparoscopically...

BACKGROUND: Laparoscopic partial nephrectomy, minimizing renal function loss due to its nephron sparing nature, has become a standard technique among many experienced centers worldwide in the surgical treatment of localized kidney tumors. Although partial nephrectomy will remain the gold standard, we need to improve perioperative management and surgical method to prevent postoperative acute kidney injury. AIMS: We aimed to demonstrate the frequency of the development of postoperative acute kidney injury following laparoscopic partial nephrectomy in patients with healthy contralateral kidney and the early predictive effects of serum neutrophil gelatinase-associated lipocalin in ischemia reperfusion injury and its association with the warm ischemia time...

BACKGROUND: Controlling of the renal vessels is a critical step in live donor nephrectomy (LDN). Currently, mainly 2 devices, Hem-o-Lok clips and staplers, are utilized to control vessels during LDN. Both of them have advantages and disadvantages. METHODS: This systematic review and meta-analysis was aimed to compare the safety and the efficacy of the 2 devices and to identify the better one in LDN. A systematic search for related publications in the databases of PubMed, Medline, Embase, the Cochrane Library, and Web of Science through February 2018 was performed...
