We report a rare case of testicular metastasis from prostate cancer. A 68-year-old patient presented with a right testicular mass with discomfort. He had a history of robot-assisted laparoscopic radical prostatectomy and had received adjuvant radiation therapy and had been treated with androgen deprivation therapy continuously at another institution. We(More)
We conducted this study to evaluate the combined effect of acellular bladder submucosa matrix (BSM) and autologous urethral tissue for the treatment of long segment urethral stricture in a rabbit model. To prepare the BSM, porcine bladder submucosa was processed, decellularized, configured into a sheet-like shape, and sterilized. Twenty rabbits were(More)
BACKGROUND The anticancer effects of selenium may be mediated by selenium-binding proteins, such as SELENBP1. The association between SELENBP1 expression levels and clinicopathologic parameters was assessed in renal cell carcinoma (RCC). METHODS SELENBP1 mRNA expression was measured with real-time quantitative polymerase chain reaction (qPCR) in 139(More)
PURPOSE Laparoscopic radical nephrectomy (LRN) has become the standard technique for radical nephrectomies for T1 renal tumors (7 cm or less). We extended our experience with LRN to T2 renal tumors (greater than 7 cm) and compared the efficacy and long-term oncologic outcomes with those of open radical nephrectomy (ORN) for T2 clear renal cell carcinoma(More)
PURPOSE We aimed to retrospectively evaluate the risk factors for hypertensive attack during adrenalectomy in patients with pheochromocytoma. Despite the development of newer surgical and anesthetic techniques for the management of pheochromocytoma, intraoperative hypertensive attack continues to present a challenge. MATERIALS AND METHODS Data from 53(More)
Upper urinary tract-derived urine stem cells (USCs) are considered a valuable mesenchymal stem cell source for autologous cell therapy. However, the reported culture condition for USCs is not appropriate for large-quantity production, because cells can show limited replicativity, senescence, and undesirable differentiation during cultivation. These(More)
PURPOSE The authors evaluated the relationships between the clinical factors and resistive indexes (RIs) of prostate and urethral blood flows by using power Doppler transrectal ultrasonography (PDUS) in men with benign prostatic hyperplasia (BPH). METHODS The data of 110 patients with BPH and lower urinary tract symptoms (LUTS) treated between January(More)
PURPOSE Preoperative percutaneous nephrostomy (PCN) can be applied to urinary stone patients with pyelonephritis as well as obstructive uropathy; thus, some patients undergo flexible ureteroscopy (fURS) in the presence of a PCN tube. We evaluated the effectiveness of PCN during fURS for the management of renal stones. MATERIALS AND METHODS We(More)
PURPOSE Laparoscopic radical nephrectomy (LRN) is more challenging with increases in body mass index (BMI). Several recent studies have shown, however, that LRN can be safely performed even in obese patients. The influence of obesity on the perioperative outcomes of LRN has not been well elucidated for large renal tumors (>7 cm), however. We estimated the(More)
