Clearance of a difficult biliary stone can be obtained using various interventional techniques such as endoscopic sphincterotomy followed by papillary large balloon dilation, mechanical lithotripsy, peroral cholangioscopy-assisted intraductal electrohydraulic/laser temporary plastic stent insertion, percutaneous transhepatic cholangioscopy-guided and extracorporeal shock wave lithotripsy. We he...

PURPOSE To study the efficiency and safety of holmium:YAG laser lithotripsy for ureteral stones. PATIENTS AND METHODS A series of 188 patients with 208 ureteral stones were treated with semirigid ureteroscopy and holmium:YAG laser lithotripsy from January 2003 to December 2005. Of the stones, 116 were lower ureteral, 37 middle ureteral, and 55 upper ureteral. RESULTS The success rate was 92...

Objective: aims to compare the success rates of laser lithotripsy with pneumatic for removing ureteric stones less than 1.5 cm at a tertiary care hospital. Method: This Multi-Center study was conducted in urology department Lady Reading Hospital Peshawar total 265 patients (125 PL group and 140 LL category) ureteral were treated ureteroscopic lithotripsy. The study's authors aimed factors such ...

OBJECTIVE To assess the fragmentation (ablation) efficiency of laser lithotripsy along a wide range of pulse energies, frequencies, power settings and different laser fibres, in particular to compare high- with low-frequency lithotripsy using a dynamic and innovative testing procedure free from any human interaction bias. MATERIALS AND METHODS An automated laser fragmentation testing system w...

BACKGROUND Laser lithotripsy is an established endourological modality. Ho:YAG laser have broadened the indications for ureteroscopic stone managements to include larger stone sizes throughout the whole upper urinary tract. Aim of current work is to assess efficacy and safety of Ho:YAG laser lithotripsy during retrograde ureteroscopic management of ureteral calculi in different locations. MET...

PURPOSE We evaluated the effectiveness and safety of holmium: YAG laser lithotripsy with a semirigid ureteroscope for ureteral calculi in a prospective cohort of 697 patients. PATIENTS AND METHODS Holmium: YAG laser lithotripsy was performed with a semirigid ureteroscope in 697 inpatients between September 2002 and January 2006. Calculi were located in the distal ureter in 382 patients (54.8%...

Efficacy and safety of pulsed dye laser lithotripsy was tested in 25 consecutive patients in whom bile duct stones could not be extracted after endoscopic sphincterotomy. The patients had one to six (mean, 1.8) bile duct stones (diameter, 10-35 mm; mean, 18 mm) located in the common bile duct (18 cases), the intrahepatic bile ducts (6 cases), or in a long cystic duct stump (1 case). Different a...
