Background Comparable oncological outcomes have been seen after surgical nephrectomy and thermal ablation of renal tumors recently. However, periprocedural outcome needs to be assessed for aiding treatment decision. Purpose To compare efficacy rates and periprocedural outcome (technical success, session time, hospitalization time, and complications) after renal tumor treatment with laparoscopic partial nephrectomy (LPN) or radiofrequency ablation (RFA). Material and Methods The initial experience with 49 (treated with LPN) and 84 (treated with RFA) consecutive patients for a single renal tumor (diameter ≤ 5 cm, limited to the kidney) during 2007-2014 was evaluated...

We report the case of a 46-year-old woman who had presented with left-sided abdominal pain 21 days after undergoing a left-sided laparoscopic nephrectomy for donation. Initial haemoglobin and haematocrit levels were within normal range, and vital signs on admission were unremarkable. Significant intra-abdominal pathology was not suspected; however, inpatient CT scan of the abdomen showed a posterolateral subcapsular splenic haematoma with free abdominal fluid. Initial trial of conservative management was not successful as the patient became hypotensive on the third day of admission with a sudden decrease in haemoglobin and haematocrit...

RATIONALE: Renal cell carcinoma associated with Xp11.2 translocations/TFE3 gene fusions is a rare subtype of renal cell carcinoma. This predominantly occurs in juveniles, but rarely seen in adults with lymph node or organic metastasis and a worsened prognosis. PATIENTS CONCERNS: Herein, we presented 3 adult cases of Xp11-RCC. Two patients were in early stage and good condition, and the third patient had lymph node metastasis but showed no recurrence after a 3-month follow-up...

The incidence of renal cell carcinoma has been rising for years. At the same time there is an increasing prevalence of chronic renal failure with subsequent higher morbidity and shorter life expectancy in those affected. In the last decades the gold standard has thus shifted from radical to partial nephrectomy or tumor enucleation. A treatment alternative can be advantageous for selected patients with high morbidity and an increased risk of complications in anesthesia or surgery. Active surveillance represents a controlled delay in the initiation of treatment with a curative intention...

Situs inversus totalis (SIT) is a rare congenital anomaly characterized by complete inversion of the thoracic and abdominal organs. Many intra-abdominal and vessel anomalies have been reported in association with SIT. However, there have been no reports on the use of laparoscopic radical nephrectomy with thrombectomy for renal vein thrombus, which is considered as a safe and feasible procedure, in patients with SIT. We herein present the case of an 80-year-old man with SIT who was preoperatively diagnosed with a right renal tumor and renal vein tumor thrombus...

BACKGROUND AND OBJECTIVES: Enhanced recovery after surgery protocols (ERAS) have been developed and implemented as of 2001. However, no previous analyses targeted length of stay (LOS) changes over time after major surgical oncological procedures (MSOPs). METHODS: Between 2003 and 2013, we retrospectively identified patients, who underwent prostatectomy, colectomy, cystectomy, mastectomy, gastrectomy, hysterectomy, nephrectomy, oophorectomy, lung resection or pancreatectomy within the Nationwide Inpatient Sample...

BACKGROUND AND OBJECTIVES: Quadratus lumborum block was first described in 2007 and currently there are descriptions of its achievement through four different injection points. This blockage provides abdominal wall and visceral analgesia, and one of its mechanisms is the dispersion of the local anesthetic into the paravertebral space. We describe the performance of a continuous quadratus lumborum type II block for postoperative analgesia in a partial nephrectomy. CASE REPORT: A 64-year-old woman, scheduled for partial left laparoscopic nephrectomy...

BACKGROUND: Renal oncocytoma is the most common benign renal tumor, and papillary renal cell carcinoma is the second most common histologic subtype of renal cell carcinoma. Renal tumors containing different components such as papillary renal cell carcinoma and oncocytoma are extremely rare. CASE PRESENTATION: A renal mass was incidentally detected in a 52-year-old Korean woman, and a computed tomographic scan showed a 32-mm multicystic mass with some calcifications in the lower pole of the right kidney...

Partial nephrectomy (PN) is the preferred surgical treatment for T1 renal tumors whenever technically feasible. When properly performed, it allows preservation of nephron mass without compromising oncologic outcomes. This reduces the postoperative risk of renal insufficiency, which translates into better overall survival for the patients. PN can be technically challenging, because it requires the surgeon to complete the tasks of tumor excision, hemostasis and renorrhaphy, all within an ischemic time of preferably below 30 minutes...

BACKGROUND: Generation of smoke is inevitable during surgical procedures. Some volatile organic compounds (VOCs) in surgical smoke are known to be strong carcinogens. We used a prototype of a multi-layered complex filter in an attempt to eliminate VOCs. METHODS: From June 2015 to July 2015, 20 patients underwent transperitoneal laparoscopic nephrectomy for renal cell carcinoma. Smoke (pre-filter) was collected 20 min after the electrocautery device was first used during the surgery, by the direct collection method, with a 5-L Tedlar® gas-sampling bag...

BACKGROUND: Living-donor nephrectomy (LDN) is challenging, as surgery is performed on healthy individuals. Minimally invasive techniques for LDN have become standard in most centers. Nevertheless, numerous techniques have been described with no consensus on which is the superior approach. Both hand-assisted retroperitoneoscopic (HARS) and hand-assisted laparoscopic (HALS) LDNs are performed at Zurich University Hospital. The aim of this study was to compare these two surgical techniques in terms of donor outcome and graft function...
