OBJECTIVE The Lumenis® High-power Holmium Laser (120H) has a unique modulated pulse mode, Moses™ technology. Moses technology modulates the laser pulse to separate the water (vapor bubble), then deliver the remaining energy through the bubble. Proprietary laser fibers were designed for the Moses technology. Our aim was to compare stone lithotripsy with and without the Moses technology. METHOD...

PURPOSE To determine the efficacy and safety of emergency ureteroscopy (URS) and holmium:yttrium-aluminum-garnet (Ho:YAG) laser lithotripsy for ureteral calculi that are associated with acute renal failure (ARF). PATIENTS AND METHODS We retrospectively evaluated a cohort of 49 patients who underwent URS from November 2005 to November 2008 for ARF that was caused by calculi obstruction of the ...

PURPOSE To present our clinical outcomes in the management of anuria in adult patients caused by ureteral calculi by using of ureteroscopy and holmium laser. MATERIALS AND METHODS Nineteen patients presented with calcular anuria with ages between 19 and 48 years. The presentation was anuria with serum creatinine levels of 2-5.5 mg% (mean 3.5) and hyperkalemia in nine patients (5.2-6.1 mmol/L)...

OBJECTIVE To evaluate in vitro and in vivo effects of Moses technology in Holmium laser and to compare it with the Regular mode in terms of lithotripsy efficiency and laser-tissue interactions. METHODS The Lumenis® Pulse™ P120H holmium laser system together with Moses D/F/L fibers were used to compare the Regular mode with the Moses modes in stone retropulsion by using a high-speed camera, an...

The majority of common bile duct stones can be effectively treated by endoscopic sphincterotomy and stone extraction using basket or balloon extractor. Stones more than 2 cm in diameter on the other hand require mechanical, electrohyraulic lithotripsy and sphincterotomy and balloon dilation. Mechanical lithotripsy may not be successful because of the size, consistency and site of the stones. In...

OBJECTIVE To analyse and compare the effect of stone site and size, method of lithotripsy, and level of experience on the results and complications of semi-rigid ureteroscopy for ureteric and renal pelvic stones. PATIENTS AND METHODS Between April 2010 and May 2011, 90 patients underwent 95 ureteroscopies, using 7.5- and 9-F semi-rigid ureteroscopes, with or without pneumatic or laser lithotr...

BACKGROUND Some tetraplegic patients may wish to undergo urological procedures without anaesthesia, but these patients can develop autonomic dysreflexia if cystoscopy and vesical lithotripsy are performed without anaesthesia. CASE PRESENTATION We describe three tetraplegic patients, who developed autonomic dysreflexia when cystoscopy and laser lithotripsy were carried out without anesthesia.I...
