Retrospective comparative study of rigid and flexible ureteroscopy for treatment of proximal ureteral stones.

Background: We analyzed the outcome and complications of rigid (R-URS) and flexible (F-URS) ureteroscopic lithotripsy for treatment of proximal ureteric stone (PUS).

Subjects And Methods: Retrospective data of 135 patients (93 males and 42 females) submitted to R-URS and F-URS for treatment of PUS in the period between July 2013 and January 2015 were investigated. (R-URS, group 1) was performed in 72 patients while 63 patients underwent (F-URS, group 2).

Expression of extracellular matrix metalloproteinase inducer and fascin in urinary bladder cancer: Correlation with clinicopathological characteristics.

Expression of extracellular matrix metalloproteinase inducer (EMMPRIN) and fascin have recently received considerable attention as emerging key markers of cell invasion and metastasis in various types of cancers. The present study aimed to characterize the expression of EMMPRIN and fascin in a cohort of bladder cancer patients and to verify the association with clinicopathological characteristics. Immunohistochemical analysis of EMMPRIN and fascin was performed in 125 bladder cancer specimens, including 86 transitional cell carcinoma (TCC) and 39 squamous cell carcinoma (SCC) cases.

Outcome of ureteroscopy for treatment of pediatric ureteral stones.

Purpose: We assess the efficacy and safety of semirigid ureteroscopy for treatment of ureteral stones in children.

Materials And Methods: The records of 18 non-consecutive children with symptomatic ureteral stones treated with ureteroscopy in 2008-2010 were reviewed. Mean age was 7.
