INTRODUCTION Currently, stone size cannot be accurately measured while performing flexible ureteroscopy (URS). We developed novel software for ureteroscopic, stone size measurement, and then evaluated its performance. METHODS A novel application capable of measuring stone fragment size, based on the known distance of the basket tip in the ureteroscope's visual field, was designed and calibrat...

30 cases of obstructing proximal ureteral stones at the level of L3-L5 which could not be pushed back into the pelvis and passed by a guide wire under epidural anesthesia, were removed percutaneously with the rigid ureteroscope. Multiple stones in one ureter, bilateral ureteral stones and a ureteral stone of a solitary kidney were removed successfully in one session showing the reliability...

With the ureterorenoscope it is now possible to perform procedures under direct vision that previously had to be undertaken blindly or with the aid of fluoroscopy. The most common use of the ureterorenoscope is for removal of ureteral calculi, particularly those that are in the distal or middle one third of the ureter. The technique of ureteral dilatation and ureteroscopy of the lower ureter vi...

When performing surgeries for ureteral stones, stenting is traditionally performed to avoid obstruction of the ureter in postoperative period due edema or stone fragments. Modern technical advances allow ureteroscopy be relatively atraumatically and routine stenting, which makes it possible exclude exacerbations pyelonephritis caused by reflux, reduce stent costs, improve quality life period, c...

Background: Stones formation is a common complication after cystectomy including stones of the upper urinary tract and reservoir or conduit. Advances in instrumentation techniques have expanded treatment options, while minimizing morbidity. Aims Objectives: Feasibility urolithiasis management diversion surgery. Materials Methods: Eleven patients with stone were observed from January 01, 2015, t...

Flexible ureteroscopy will replace almost completely ESWL for the treatment of renal stones in few years, even in developing countries. This process is already ongoing and probably is irreversible. Let ́s try to understand how and why this phenomenon is happening. Since the development of the External Shockwave Lithotripsy (ESWL) in the late 70’s (1), it has been the standard treatment for small...
