The authors present two cases of primary synovial sarcoma of the kidney. Both patients had a tumor mass in the kidney with vascular invasion of the inferior vena cava and right atrium of the heart in case no. 1. In case no. 2 retroperitoneal lymph node metastasis and multiple metastases to both lungs were observed. Radical nephrectomies were performed in(More)
UNLABELLED INTRODUCTION Training systems for laparoscopic surgery are useful for basic training but are not suitable for specific training corresponding to the condition of a given patient. We, therefore, have developed an unusual training system: a patient-specific simulator for laparoscopic surgery. When specific data of each individual patient are(More)
At the Advanced Medical Research Center at Yokohama City University School of Medicine, we have been developing a practical surgical simulator for renal surgery. Unlike already commercialized laparoscopic surgical simulators, our surgical simulator is capable of using patient-specific models for preoperative training and improvement of laparoscopic surgical(More)
The juxtaglomerular cell tumor (JGCT) is a rare renal tumor characterized by excessive renin secretion causing intractable hypertension and hypokalemia. However, asymptomatic nonfunctioning JGCT is extremely rare. Here, we report a case of nonfunctioning JGCT in a 31-year-old woman. The patient presented with a left renal tumor without hypertension or(More)
PURPOSE When retroperitoneoscopic radical nephrectomy for renal cell carcinoma was introduced into our institution, we performed a combined small skin incision method. In this method, a small incision was made to approach the retroperitoneal space prior to setting trockers and thereafter a LAPDISC was placed in the incision to start the retroperitoneoscopic(More)
Dialysis patients have a tendency to bleed, and clinicians sometimes encounter cases with a significant amount of spontaneous hemorrhage. We herein report two cases of spontaneous renal hemorrhage in hemodialysis patients. CASE 1: A 70-year-old male who had received hemodialysis for 8 years presented with right abdominal pain. He had a history of renal(More)

The neutrophil-to-lymphocyte ratio (NLR), a simple marker of the systemic inflammatory response, has been demonstrated to correlate with patient outcomes for various solid malignancies. We investigated the utility of the pretreatment NLR as a prognosticator in patients who presented with penile cancer. A total of 41 patients who underwent complete blood(More)
The neutrophil-to-lymphocyte ratio (NLR), a simple marker of the systemic inflammatory response in critical care patients, has been suggested as an independent prognostic factor for several solid malignancies. We investigated the utility of pretreatment NLR as a prognosticator in patients who presented with metastatic prostate cancer. We first investigated(More)
There is no reliable biomarker for predicting the prognosis of patients who undergo radical cystectomy for bladder cancer. Recent studies have shown that the neutrophil-to-lymphocyte ratio (NLR) could function as a useful prognostic factor in several types of malignancies. This study aimed to assess the usefulness of NLR in bladder cancer. A total of 74(More)
