Prostate cancer is the second leading cause of cancer-related death among men in the United States. More recently, immature colon carcinoma transcript 1 (ICT1) has been reported to be overexpressed in various kinds of cancer cells. However, the role of ICT1 in human prostate cancer has not yet been determined.

Objective: To summarize our preliminary clinical experiences of laparoendoscopic single-site (LESS) retroperitoneal adrenalectomy.

Methods: Since October 2009 to January 2011, the investigators have performed LESS retroperitoneal adrenalectomy for 7 patients with adrenal tumors. A waist axillary midline incision of around 2 - 3 cm was made and a single incision for inserting a homemade port.

MED19 is a member of the Mediator that plays a key role in the activation and repression of signal transduction or the regulation of transcription in carcinomas. To tested the functional role of MED19 in human prostate cancer, we downregulated MED19 expression in prostate cancer cells (PC-3 and DU145) by lentivirus-mediated short hairpin (shRNA), and analyzed the effect of inhibition of MED19 on prostate cancer cell proliferation and tumorigenesis. The in vitro prostate cancer cell proliferation, colony formation, and in vivo tumor growth in nude mice xenografts was significantly reduced after the downregulation of MED19.

Laparoscopic radical prostatectomy is considered the first treatment of choice for local prostate cancer due to its minimal invasion advantage. To further achieve the goal of minimal invasion, single port laparoscopic radical prostatectomy has been developed to minimize the complications associated with puncture tracks. The aim of this study was to illustrate the technique for single port laparoscopic radical prostatectomy and evaluate its efficacy and safety.

Objectives: To determine the prevalence of dysfunctional voiding (DV) in female stress urinary incontinence (SUI) and its modification after tension-free vaginal tape (TVT) procedure.

Methods: Three hundred and sixty women with SUI were enrolled and underwent urodynamics from 2002 to 2008. DV was determined when non-neurogenic detrusor-sphincter dyssynergia occurred during voluntary voiding.
