Microureteroscopy in Children: Two First Cases.

Background: Urinary stones disease is becoming more common not only in adults but also in children. Most cases are resolved with extracorporeal shock wave lithotripsy, but miniaturization of endoscopes has increased the use of ureteroscopy in resolving ureteral stones, most notably in children.

Case Presentation: This presentation focuses on two cases of microureteroscopy.

Incidence of infectious complications after extracorporeal shock wave lithotripsy in patients without associated risk factors.

Purpose: We determined the incidence of infectious complications (asymptomatic bacteriuria, urinary tract infection and urosepsis) in patients without associated risk factors treated with extracorporeal shock wave lithotripsy.

Materials And Methods: We performed an observational, prospective cohort study between October 2010 and June 2013. We included all patients without risk factors who were treated with extracorporeal shock wave lithotripsy for kidney or ureteral lithiasis.

How to expand the service life of flexible nephroscopes? Put a sheath on!

Technologic advances in endourologic surgical material have led to improved image quality, power sources, and auxiliary material (probes, nitinol baskets, etc.). Nevertheless, this material is more expensive, especially the flexible endoscopic material--ureterorenoscopes and nephroscopes.
