We studied the sapphire and germanium fibers to determine which optical fiber best transmits Erbium:YAG laser for intracorporeal lithotripsy. Human calculi were ablated with an Erbium:YAG laser in contact mode using two fibers. Optical outputs at the distal end of fibers were measured before and after laser lithotripsy. Upon the irradiation on the calculus with the 50 mJ and 100 mJ pulse energy...

BACKGROUND AND OBJECTIVES Advances in endoscopic techniques have transformed the management of urolithiasis. We sought to evaluate the role of such urological interventions for the treatment of complex biliary calculi. METHODS We conducted a retrospective review of all patients (n=9) undergoing percutaneous holmium laser lithotripsy for complicated biliary calculi over a 4-year period (12/200...

Abstract Laser Lithotripsy is a therapeutic technique commonly used for the treatment of urological stones. This report presents case patient with common bile duct (CBD) stone refractory to traditional management approaches including ERCP, internal and external drains. A plan was made undergo laser lithotripsy their CBD in multi-disciplinary procedure. high-power Holmium laser, operated by Urol...

OBJECTIVES The aim of this study was to assess the safety and effectiveness of ureteroscopy and Holmium: Yttrium-Aluminum-Garnet lithotripsy for the treatment of ureteral stones with different localizations in symptomatic pregnant women. METHODS A retrospective analysis was performed on 19 pregnant patients referred to our center between January 2005 and December 2012 with symptomatic hydrone...

The patient was a 58-year-old man with a long-standing history of alcohol abuse and chronic pancreatitis leading to multiple hospitalizations. He continued to have pain despite conservative management, pain control, and alcohol cessation. His chronic pancreatitis and pancreatic duct (PD) stones resulted in a tight PD stricture at the head of the pancreas. Multiple prior attempts at conventional...

PURPOSE A prospective randomized controlled trial was conducted to evaluate whether postoperative ureteral stenting is necessary after ureteroscopic laser lithotripsy. MATERIALS AND METHODS A total of 58 patients with unilateral ureteral stones were randomized into either stented or unstented groups. Ureteroscopic laser lithotripsy was performed using a semirigid ureteroscope (6.5/7Fr) and ho...

A 38-year-old man with chronic pancreatitis caused by heavy alcohol consumption presented with recurrent abdominal pain due to underlying pancreatic duct calculi and stricture of the main pancreatic duct (▶Fig. 1 a). Endoscopic cholangiopancreatography (ERCP) was performed and a plastic pancreatic stent was inserted, which relieved the pain. Attempts at stricture dilation with a dilation balloo...

Introduction: The aim of this study was to compare the results and complications of extracorporeal shock wave lithotripsy (SWL) plus retrograde ureteroscopic lithotripsy using laser and pneumatic lithotriptors with SWL monotherapy for renal pelvic calculi between 2 cm and 3 cm. Materials and Methods: A total of 55 patients with 2to 3-cm pelvic calculi were assigned into groups 1 and 2, includin...

Two hundred and fifty patients with 290 stones presenting to the Department of Urology were treated with the Candela MDL 2000 Laser Lithotripter. Overall stone clearance rate was 95%. The more proximal the calculus the lower the success rate. Ninety eight percent of stones in the lower ureter, 95% of mid ureteric and 91% of upper ureteric stones were cleared. The major complication was perforat...
