Zi Qin Ng, Richard Pemberton, Patrick Tan
Trocar site hernia is not a common acute complication encountered after robot-assisted surgery, especially in the urological cohort of patients. A few case reports of small bowel obstruction secondary to incarceration by trocar site hernia have been described in gynaecological surgery and prostatectomies. As the clinical presentation is non-specific, late diagnosis has significant implication on morbidity and mortality. Here, we present a rare case of a patient with recent robot-assisted laparoscopic partial nephrectomy for a renal cell carcinoma presented with features of impending bowel obstruction secondary to incarcerated small bowel in the trocar site...

Background: Germline mutations in succinate dehydrogenase (SDH) are associated with multifocal cancers: pituitary gland tumors, pheochromocytomas, paragangliomas, gastrointestinal stromal tumors, and renal-cell carcinomas (RCCs). SDH-deficient renal-cell carcinoma (SDH-RCC) was first identified in 2004 as an inherited kidney cancer with mutations in the SDH gene. SDH consists of A, B, C, and D units. Mutation in the SDHB gene is the most common mutation in SDH-deficient RCCs. Case Presentation: We report a case of a 51-year-old healthy man diagnosed with SDHB germline mutation and RCCs...

Multilocular cystic renal cell carcinoma (MCRCC), which exhibits low-stage and low-grade characteristics, is a special type of RCC. MCRCC is extremely rare and generally develops at ages >50 years. We herein report a case of MCRCC in a 28-year-old man, which, to the best of our knowledge, is the youngest case reported worldwide to date. The patient presented with irritative bladder symptoms for 1 year. Dynamic enhanced computed tomography (CT) imaging revealed a mass with inhomogeneous enhancement in the left kidney, with a rich blood supply...

REVIEW

Renal cell cancer is nowadays predominantly diagnosed in early stages due to the widespread use of sectional imaging for unrelated symptoms. Small renal masses (<4 cm) feature a largely indolent biology with a very low risk for metastasis or even a benign biology in up to 30% of the cases. Consequently, there is a need for less invasive therapeutic alternatives to nephron-sparing surgery. Meanwhile, there is a broad portfolio of local ablation techniques to treat small renal tumors. These include the extensively studied radiofrequency ablation and cryoablation techniques as well as newer modalities like microwave ablation and irreversible electroporation as more experimental techniques...

Reports for pediatric kidney transplant recipients suggested better outcomes for ODN compared to LDN. Contemporary outcomes stratified by donor type and center volume have not been evaluated in a national dataset. UNOS data (2000-2014) were analyzed for pediatric living donor kidney transplant recipients. The primary outcome was GF; secondary outcomes were DGF, rejection, and patient survival. Live donor nephrectomies for pediatric recipients decreased 30% and transitioned from ODN to LDN. GF rates did not differ for ODN vs LDN (P = ...

INTRODUCTION: The relative impact of preoperative and perioperative variables on renal function following partial nephrectomy (PN) is controversial. To further investigate, we assess the effects of tumour complexity, warm ischemic time (WIT), and volume of resected renal parenchyma on ipsilateral renal function (IRF) outcomes following minimally invasive PN. METHODS: Of patients who underwent laparoscopic or robotic-assisted PN between 2002 and 2011 at our institution, 99 met our inclusion criteria...

INTRODUCTION: In recent years, the method of vascular control during laparoscopic donor nephrectomy (LDN) has come under scrutiny due to catastrophic consequences of a device failure. This study sought to examine the surgical preferences of Canadian donor surgeons with regards to vascular control and their perception on the safety of these modalities. We also surveyed the experience with device malfunction and their subsequent management during LDN. METHODS: An online survey was sent out to donor surgeons registered with the Canadian Society of Transplantation...

BACKGROUND: We report an unusual case of a synchronous rectal and metachronous vaginal metastatic renal cell carcinoma. CASE PRESENTATION: A 78-year-old woman presented with hematochezia and a colonoscopy revealed a metastatic clear-cell renal cell carcinoma rectal polyp biopsy-proven. Abdominal computed tomography identified a 9.0-cm left renal mass with renal vein thrombosis, for which she underwent a laparoscopic radical nephrectomy. Histopathological examination confirmed a pT3a clear-cell renal cell carcinoma...

Intraoperative occlusion of the renal artery during laparoscopic partial nephrectomy results in warm ischemia and nonspecific hypoxia-reoxygenation alteration of the renal parenchyma cells with a predominant injury to epitheliocytes of the proximal segments of the tubular nephron system. The onset and development of acute kidney injury (AKI) syndrome, which requires immediate correction, is due to the typical pathological process of cell injury. In this regard, the issue of timely diagnosis of AKI remains highly relevant...

PURPOSE OF REVIEW: The purposes of this review were to identify the possible limiting factors prohibiting laparoscopic nephrectomy being performed as an outpatient surgery and optimize these limiting factors. RECENT FINDINGS: Laparoscopic nephrectomy for patients who have kidney cancer can be performed as an outpatient surgery in well-selected, well-educated, and well-informed patients in a well-prepared hospital culture. Patient confidence, pain, and hospital culture are the most important limiting factors to the performance of laparoscopic nephrectomy as an outpatient procedure...
