OBJECTIVE To elucidate clinicopathologic independent prognostic factors for intravesical recurrence after laparoscopic nephroureterectomy for primary upper urinary tract urothelial carcinoma (UUT-UC). METHODS AND MATERIALS This study included 212 consecutive patients clinically diagnosed as localized UUT-UC and treated by retroperitoneal laparoscopic(More)
BACKGROUND This study compared the efficacy and safety between 120-W thulium:yttrium-aluminum-garnet (Tm:YAG) vapoenucleation of prostates (ThuVEP) and holmium laser enucleation of prostates (HoLEP) for patients with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). METHODS A retrospective analysis of 88 consecutive patients(More)
Vasoepididymostomy (VE), as the most challenging procedure in microsurgeries, is often carried out with a double-armed two-suture technique. In this study, we evaluated the efficacy and safety of the single-armed two-suture VEs on humans and studied the factors that could possibly affect the patency rates. From July 2012 to July 2013, we reviewed 81(More)
BACKGROUND AMP-activated protein kinase (AMPK) is an important enzyme in regulation of cellular energy homeostasis. We have previously shown that AMPK activation by 5-aminoimidazole-4-carboxamide (AICAR) results in suppression of immune responses, indicating the pivotal role of AMPK in immune regulation. However, the cellular mechanism underpinning AMPK(More)
OBJECTIVES We present preliminary experience of retroperitoneal laparoscopic nephroureterectomy (RPLNU) with bladder cuff excision by combining cystoscopic resection with open transperitoneal dissection for native upper urinary tract transitional cell carcinoma (UUT-TCC) ipsilateral to a transplanted kidney. METHODS Thirteen renal recipients with native(More)
OBJECTIVE To evaluate urinary continence outcomes after laparoscopic radical prostatectomy (LRP), and explore the learning curve for continence. METHODS Between May 2006 and May 2011, 200 consecutive patients with clinically localized prostate cancer underwent LRP in Peking University Third Hospital, of whom 160 were performed by a single surgeon and(More)
Inflammatory bowel disease (IBD) is characterized by excessive innate immune cell activation, which is responsible for tissue damage and induction of adaptive immune responses. All-trans retinoic acid (ATRA), the ligand of retinoic acid receptors (RAR), has been previously shown to regulate adaptive immune responses and restore Th17/Treg balance, while its(More)
BACKGROUND Ascorbic acid has important antioxidant properties, and may play a role in the protective effects of ischemic preconditioning on later ischemia-reperfusion. Herein, we examined the role of endogenous extracellular ascorbic acid in ischemic preconditioning in the kidney. METHODS We developed a solitary rabbit kidney model where animals received(More)
OBJECTIVE To investigate the knowledge of and attitude to sexual dysfunction in aged men, and to discuss the status and needs of male healthcare. METHODS Two thousand seven hundred and twenty-eight men (40-70 years old) were surveyed on sexual dysfunction using the randomized questionnaire in Xicheng District, Beijing. RESULTS The prevalence of erectile(More)
OBJECTIVE To investigate the epidemiological changes of erectile dysfunction (ED) patients in the past five years. METHODS In 2003 and 2008, we conducted two questionnaire investigations on the epidemiological changes of ED outpatients in 11 Chinese cities in such aspects as age, disease course, ED severity, smoking and drinking habits, accompanying(More)
