Effectiveness of Intrarectal Povidone-iodine Cleansing Plus Formalin Disinfection of the Needle Tip in Decreasing Infectious Complications After Transrectal Prostate Biopsy: A Randomized Controlled Trial.

Purpose: Prostate biopsy is mostly performed through the transrectal route worldwide and infectious complications may occur in up to 7% of cases. Therefore, alternative strategies to decrease infectious complications are needed. Our aim was to evaluate the effectiveness of intrarectal povidone-iodine cleansing plus formalin disinfection of the needle tip in decreasing infectious complications after transrectal ultrasound guided prostate biopsy.

Immune expression of E-cadherin and α, β and γ-Catenin adhesion molecules and prognosis for upper urinary tract urothelial carcinomas.

Introduction: Cell adhesion molecules (CAM) are required for maintaining a normal epithelial phenotype, and abnormalities in CAM expression have been related to cancer progression, including bladder urothelial carcinomas. There is only one study that correlates E-cadherin and Α-, Β- and y-catenin expression with prognosis of upper tract urothelial carcinomas. Our aim is to study the pattern of immune expression of these CAMs in urothelial carcinomas from the renal pelvis and ureter in patients who have been treated surgically.
