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...

OBJECTIVE: To evaluate the efficacy and safety of self-retaining barbed suture in renorrhaphy during laparoscopic partial nephrectomy by comparing surgical outcomes in a prospective randomized manner. MATERIAL AND METHODS: From July 2014 to July 2015, a total of 60 patients with T1 renal tumor were randomized into two equal groups: self-retaining barbed suture (SRBS) and conventional absorbable polyglactin suture (non-SRBS group). All patients were treated by retroperitoneal laparoscopic partial nephrectomy...

PURPOSE: This study aimed at reporting the long-term oncological outcomes of robotic partial nephrectomy (RPN) for renal cell carcinoma (RCC). METHODS: Data from all consecutive patients who underwent RAPN for RCC from July 2009 to January 2012 in three departments of urology were prospectively collected. Overall survival (OS), cancer-specific survival (CSS) and disease free-survival (DFS) were estimated using the Kaplan-Meier method. Prognostic factors associated with CSS were sought in univariate analysis...

OBJECTIVE: To compare oncological and functional mid-term outcomes following robotic partial nephrectomy (RPN) and radiofrequency ablation (RFA) for treating T1a renal cell carcinoma (RCC) using propensity score-matching. METHODS: Between December 2008-April 2016, 63 patients from each treatment group were propensity score-matched for age, sex, American Society of Anesthesiologists score, tumour size, tumour laterality, tumour histology, R.E.N.A.L. nephrometry score and preoperative estimated glomerular filtration rate (eGFR)...

CONTEXT: During robotic partial nephrectomy (RPN), various techniques of hilar control have been described, including on-clamp, early unclamping, selective/super-selective clamping, and completely-unclamped RPN. OBJECTIVE: To evaluate the impact of various hilar control techniques on perioperative, functional, and oncological outcomes of RPN for tumors. EVIDENCE ACQUISITION: We conducted a systematic literature review and meta-analysis of all comparative studies on various hilar control techniques during RPN using PubMed, Scopus, and Web of Science according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement, and Methods and Guide for Effectiveness and Comparative Effectiveness Review of the Agency for Healthcare Research and Quality...

Objectives To provide a training tool to address the technical challenges of robot-assisted laparoscopic partial nephrectomy, we created silicone renal tumor models using 3D printed molds of a patient's kidney with a mass. In this study, we assessed the face, content, and construct validity of these models. Materials and Methods Surgeons of different training levels completed four simulations on silicone renal tumor models. Participants were surveyed on the usefulness and realism of the model as a training tool...

OBJECTIVES: To determine the complexity of renal masses by using an objective novel imaging parameter (intraparenchymal tumor volume) based on computed tomography scans, to correlate this parameter to perioperative outcomes and to the RENAL nephrometry score. METHODS: After institutional review board approval, 87 patients who underwent partial nephrectomy between 2012 and 2016 at Singapore General Hospital, Singapore, were retrospectively analyzed. Preoperative computed tomography intravenous pyelogram scans were reviewed by a single senior radiologist who calculated the intraparenchymal tumor volume...

To determine the suitability of serum endocan (ESM-1) levels for diagnosing and monitoring renal cell carcinoma (RCC), we measure serum ESM-1 levels in 56 RCC patients who had undergone radical or partial nephrectomies and 56 age- and sex-matched healthy kidney donors. Measurements were made before and 1 month and 3 months after surgery. The areas under the curve (AUCs) were determined from receiver operating characteristic (ROC) analyses. RCC patients had higher mean serum ESM-1 levels than control subjects (0...

We present the case of a young woman found to have an exophytic solid renal mass who was referred to our institution for ablation of said mass versus partial nephrectomy. The patient had a history of splenectomy. Ultrasound demonstrated a homogeneous solid left renal mass, and the diagnosis of intra-renal splenosis was considered based on the patient's history. The diagnosis was confirmed using Tc-99 m heat-damaged red blood cell scintigraphy, obviating the need for an invasive procedure. The diagnosis of intra-renal splenosis should be considered for a solid renal mass with an appropriate history of prior splenic trauma or splenectomy...

BACKGROUND: The increase in the prevalence of end-stage renal disease in developed countries and the shortage of deceased donors have made it necessary to increase the graft pool by means of several strategies, such as living donation, non-heart-beating organ donors, and expanded-criteria donors. This study aimed to assess the short-term outcomes of donor kidneys with small (≤3.5 cm) renal cell carcinoma (sRCC) and to evaluate the possibility of using marginal kidneys in renal transplantation...

INTRODUCTION: Once used primarily in the identification of renal metastasis and lymphomas, various urological bodies are now adopting an expanded role for the renal biopsy. We sought to evaluate the role of the renal biopsy in a Canadian context, focusing on associated adverse events, radiographic burden, and diagnostic accuracy. METHODS: This retrospective review incorporated all patients undergoing ultrasound (US)/computed tomography (CT)-guided biopsies for T1 and T2 renal masses...

BACKGROUND: Historically, partial nephrectomy (PN) showed no benefit on other-cause mortality (OCM) in elderly patients with small renal masses. OBJECTIVE: To test the effect of PN versus radical nephrectomy (RN) on OCM, cancer-specific mortality (CSM), as well as 30-d mortality in patients with nonmetastatic T1a renal cell carcinoma (RCC), aged ≥75 yr old. DESIGN, SETTING, AND PARTICIPANTS: Within the Surveillance, Epidemiology and End Results registry (2004-2014), we identified surgically treated patients with nonmetastatic pT1a RCC aged ≥75 yr...

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...

A 78-year-old woman underwent partial hepatectomy for the treatment of hepatocellular carcinoma(HCC).After surgery, she was further treated with radiofrequency ablation(RFA)and transcatheter arterial embolization(TAE)for the intrahepatic reccurence of HCC.Thirty months after surgery, her tumor marker levels increased and computed tomography (CT)revealed an intrahepatic mass and right renal tumor which extended into the renal vein.We therefore suspected a reccurence of HCC and right renal cell carcinoma which extended into the renal vein, and thus performed right nephrectomy before again performing TAE to treat the reccurence of HCC...
