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)
BACKGROUND AND OBJECTIVES To assess the effect of surgical wait time on the oncologic outcomes of patients with upper urinary tract urothelial carcinoma (UTUC), particularly in the ureter. METHODS Using an optimal surgical wait time cutoff value of 30.5 days, we allocated patients to an early group or a late group. Cancer specific survival (CSS) and(More)
OBJECTIVE To evaluate the efficacy and feasibility of nontransected ventral onlay-augmented urethroplasty using an autologous saphenous vein graft in a rabbit model of urethral stricture. METHODS Ten white male rabbits weighing 3.0-3.5 kg were selected, and a long tract urethral stricture was generated by excising an 0.8-cm wide and 2-cm long portion of(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)
OBJECTIVE Preoperative percutaneous nephrostomy (PCN) has been commonly performed for patients with urinary stones complicated with pyelonephritis or obstructive uropathy; in fact, a considerable number of patients undergo ureteroscopic removal of stone (URS) in the presence of a PCN. We assessed the effectiveness of PCN during URS in the management of(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 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)
Atmospheric (in vitro) oxygen pressure is around 150 mm Hg (20% O2), whereas physiologic (in vivo) oxygen pressure ranges between 5 and 50 mm Hg (0.7–7% O2). The normoxic environment in cell culture does not refer to a physiological stem cell niche. The aim of this study is to investigate the effect of oxygen concentration on cell properties of human(More)
