AIM: To evaluate the Mayo Adhesive Probability (MAP) score, renal pelvis score, and RENAL nephrometry score for the prediction of surgical outcome in patients with renal masses undergoing laparoscopic partial nephrectomy at a single center. PATIENTS AND METHODS: A total of 280 patients who underwent laparoscopic partial nephrectomy were identified retrospectively. Thirty-eight patients were excluded because of a lack of preoperative imaging. The outcome measures included surgical technique, patient characteristics, MAP score, renal-pelvis-score, RENAL nephrometry score, and complication rates according to the Clavien-Dindo classification...

This report presents a case of a 46-year-old woman in whom contralateral pneumothorax occurred during retroperitoneal laparoscopic donor nephrectomy without any evidence of diaphragmatic injuries. After the start of carbon dioxide-induced pneumoperitoneum, the patient's end-tidal carbon dioxide pressure and heart rate suddenly increased. The surgery was then paused, and a chest X-ray revealed a right pneumothorax accompanied by pneumomediastinum. After a thoracostomy tube was inserted, these symptoms immediately improved...

INTRODUCTION: The adoption of robot-assisted laparoscopic (RAL) procedures in the field of urology has occurred rapidly, but is, to date, without pediatric-specific instrumentation. Surgical fog is a significant barrier to safe and efficient laparoscopy. This appears to be a significant challenge when adapting three-dimensional 8.5-mm scopes to use in pediatric RAL surgery. The objective of the present study was to compare matched controls from a prospectively collected database to procedures that were performed utilizing special equipment and a protocol to minimize surgical fog in pediatric RAL procedures...

BACKGROUND: In a preliminary experience, we claimed the potential value of 3D printing technology for pre-operative counseling and surgical planning. However, no objective analysis has ever assessed its additional benefit in transferring anatomical information from radiology to final users. We decided to validate the pre-operative use of 3D-printed anatomical models in patients with solid organs' diseases as a new tool to deliver morphological information. METHODS: Fifteen patients scheduled for laparoscopic splenectomy, nephrectomy, or pancreatectomy were selected and, for each, a full-size 3D virtual anatomical object was reconstructed from a contrast-enhanced MDCT (Multiple Detector Computed Tomography) and then prototyped using a 3D printer...

We report an unusual case of pancreatic fistula after transperitoneal laparoscopic left radical nephrectomy. A 43 years old male patient presented with severe abdominal pain and abdominal distension 71 day after the surgery. Computerized tomography (CT) demonstrated a large fluid collection in the operated renal fossa. The treatment, which comprised percutaneous drainage led to a closure of the fistula 20 days after therapy.

Patients with renal insufficiency receiving long-term hemodialysis often develop so-called hemodialysis amyloidosis characterized by systemic β 2-microglobulin amyloid lesions, while patients with renal cell carcinoma may develop amyloid A(AA) amyloidosis. Herein, we present a 67-year-old man on thirty-yearlong hemodialysis who was diagnosed to have left renal cell carcinoma coincident with a large spaceoccupying lesion adjacent to the psoas muscle in the pelvic cavity. An ultrasound-guided percutaneous needle biopsy was performed at the time of laparoscopic radical nephrectomy...

Background: Hand-assisted laparoscopic donor nephrectomy is a minimally invasive procedure for living kidney donation. The surgeon operative volume is associated with postoperative morbidity and mortality. We evaluated the risk factors associated with decreased renal function after hand-assisted laparoscopic donor nephrectomy performed by a single experienced surgeon. Methods: We included living renal donors who underwent hand-assisted laparoscopic donor nephrectomy by a single experienced surgeon between 2006 and 2013...

BACKGROUND: Postoperative recovery after live donor nephrectomy is largely determined by the consequences of postoperative pain and analgesia consumptions. The use of deep neuromuscular blockade has been shown to reduce postoperative pain scores after laparoscopic surgery. In this study, we will investigate whether deep neuromuscular blockade also improves the early quality of recovery after live donor nephrectomy. METHODS: The RELAX-study is a phase IV, multicenter, double-blinded, randomized controlled trial, in which 96 patients, scheduled for living donor nephrectomy, will be randomized into two groups: one with deep and one with moderate neuromuscular blockade...

OBJECTIVE: Kidney transplantation from a living donor nephrectomy (LDN) is the best treatment for end-stage renal disease, but decrease in donor renal function is often revealed. The aim of this study was to evaluate the association between preoperative factors and postoperative estimated glomerular filtration rate (eGFR) and test a predictive model to estimate postoperative eGFR, 1 year after LDN. PATIENTS AND METHODS: We reviewed 226 records of consecutive patients who underwent laparoscopic live donor nephrectomy between 2006 and 2014 in a single tertiary center...

BACKGROUND: Thyroid metastases to distant sites are uncommon incidents, most often metastasizing to the lungs and bones. Rates of metastasis to the kidney are particularly low, ranging from 2.8-3.8% for papillary and 6-20% for follicular variants of well-differentiated thyroid cancers (WDTCs). In rare instances, tumor-to-tumor metastasis between two true primary neoplasms can occurs. This medical phenomenon has previously occurred as a clear cell renal cell carcinoma (CCRCC) spreading to a WDTC...
