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).

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.
