We conducted a literature review of natural orifice transluminal endoscopic surgery (NOTES), focusing on urologic procedures with gastrointestinal tract access, to update on the development of this novel surgical approach. As part of the methods, a comprehensive electronic literature search for NOTES was conducted using PubMed and Cochrane Library from March 2002 to February 2016 for papers reporting urologic procedures performed utilizing gastrointestinal tract access. A total of 11 peer-reviewed studies examining utility of gastrointestinal access for NOTES urologic procedures were noted, with the first report in 2007...

Reninoma is a tumor that secretes excessive renin and is a rare cause of secondary hypertension. We report a case of reninoma with delayed diagnosis in a 33-year-old woman taking an angiotensin receptor blocker. During angiotensin receptor blocker medication, she had exhibited no electrolyte abnormality. The angiotensin receptor blocker was stopped for pregnancy planning purposes, and subsequent hypokalemia was observed. Abdominal computed tomography showed an enhanced round mass in the right kidney. Right partial nephrectomy was performed and the renal mass was removed...

Pleomorphic Hyalinizing Angiectatic Tumor (PHAT) is a rare benign lesion characterized by slow growth, infiltrative behavior and high rate of local recurrences. Only one case has been described in retroperitoneum, at renal hilum, but not involving pelvis or parenchyma. Here we present the first case of PHAT arising in the renal parenchyma. A nodular lesion in right kidney lower pole was diagnosed to a 61 year old woman. The patient underwent right nephrectomy. Microscopically, the lesion showed solid and pseudo-cystic components with hemorrhagic areas characterized by aggregates of ectatic blood vessels...

PURPOSES: Although several anatomical classification systems that aimed to standardize the description of renal tumors were previously reported, a special classification system is required to help predict the complexity and perioperative outcomes of off-clamp nephron-sparing surgery (NSS). We developed a novel criterion-zero ischemia index (ZII), aiming to help predict the perioperative outcomes after off-clamp NSS and guide patient selection. METHODS: We retrospectively evaluated 149 patients between June 2009 and July 2014 in our institution who underwent off-clamp NSS with available computed tomography images...

Renal cell carcinoma (RCC) accounts for more than 2% of neoplasias in humans worldwide. Renal biopsy is the gold standard among the diagnostic procedures, but it is invasive and not suitable for all patients. Therefore, new reliable and non-invasive biomarkers for RCC are required. Secretion of extracellular vesicles (EVs), containing RNA molecules that can be transferred between cells, appears to be a common feature of neoplasia. Consistently, cancer-derived EVs are increased in blood and urine. Therefore, urinary samples may be a non-invasive approach for discovering new diagnostic biomarkers...

Background: The development of laparoscopic and robotic surgeries represents the modern era with the objective of improving patient outcomes; this surgical method is widespread in urology and general surgery. Retroperitoneal laparoscopic/robotic surgery is common in urologic surgery, but not in liver surgery. Tumors located in the posterosuperior aspect of the liver are difficult to access using a transperitoneal approach, and control of bleeding can also be difficult, especially in patients with cirrhosis...

Partial nephrectomy is now the preferred surgical option for small renal tumors because it allows nephron preservation without compromising oncologic clearance. Its outcomes depend on the surgeon's ability to continuously identify the edges of the tumor during resection, thus leaving an adequate margin around the tumor without excessive removal of normal parenchyma, as well as keeping a short ischemic time. Folate receptors are highly abundant in the normal kidney, and there is a difference in folate receptor expression between malignant and normal renal tissues...

BACKGROUND: Two main techniques are adopted to perform partial nephrectomy in children: laparoscopy and retroperitoneoscopy. The aim of this paper is to review the larger multicentric experience recently published by our group to review indications, techniques and results of both approaches. METHODS: Data of 102 patients underwent partial nephrectomy in a 5-year period using minimally invasive surgery (MIS) procedures were analyzed. Fifty-two children underwent laparoscopic partial nephrectomy (LPN), and 50 children underwent retroperitoneoscopic partial nephrectomy (RPN)...

Renal cell carcinoma with TFEB rearrangement [t(6;11)(p21;q13)] was initially recognized to be composed of dual populations of large cells with clear cytoplasm and small cells forming rosettes around hyaline material. With increasing awareness, however, the spectrum of described morphology has been found to be more heterogeneous. We report a 54 year-old woman who underwent partial nephrectomy for a 2.4 cm renal mass, composed of fibrosis, hyalinization, calcification and ossification, and a smaller component of epithelioid cells...

OBJECTIVES: To evaluate trends in peri-operative outcomes of 250 consecutive cases beyond the initial learning curve (LC) of robot-assisted partial nephrectomy (RAPN) among multiple surgeons. PATIENTS AND METHODS: A multi-institutional database was used to evaluate trends in patient demographics (e.g. age, gender, comorbidities), tumour characteristics (e.g. size, complexity) and peri-operative outcomes (e.g. warm ischaemia time [WIT], operating time, complications, estimated blood loss [EBL], trifecta achievement) in consecutive cases 50-300 (n = 960) from 2008 to 2016 among four experienced surgeons...

REVIEW
Hiroshi Miyamoto
Despite significant advances in patient selection as well as surgical technique over the past few decades, it is still not uncommon for patients with urological malignancy and positive surgical margins to be observed. Meanwhile, intraoperative pathology consultation with frozen section assessment, which generally provides useful information for the optimal procedure, has been widely utilized for the assessment of surgical margins during urological surgeries. Thus, it remains unanswered whether intraoperative frozen section assessment has an impact on final surgical margin status as well as long-term oncological outcomes...
