OBJECTIVE To evaluate the clinical efficiency of alpha1-adrenergic antagonists on stentless ureteroscopic lithotripsy treating uncomplicated lower ureteral stones. MATERIALS AND METHODS From January 2007 to January 2013, 84 patients who have uncomplicated lower ureteral stones treated by ureteroscopic intracorporeal lithotripsy with the holmium laser were analyzed. The patients were divided i...

Colonic gallstone ileus in an uncommon mechanical bowel obstruction caused by intraluminal impaction of one or more gallstones. The surgical management of gallstone ileus is complex and is potentially of high risk. There have been reports of gallstone extractions using various endoscopic modalities to relieve the obstruction. In this report we present the technique employed to successfully perf...

INTRODUCTION Among the complications of extracorporeal shock wave lithotripsy are perinephric bleeding and hypertension. CASE PRESENTATION We describe the case of a 31-year-old Asian man with an unusual case of hemoptysis and lung contusion and cavitation with exudative plural effusion due to pulmonary trauma following false positioning of extracorporeal shock wave lithotripsy. Differential d...

Pulmonary oedema in a patient with hypertrophic subaortic stenosis undergoing extracorporeal shock wave lithotripsy is described. This event occurred upon emergence from the bath. It is suggested that pulmonary oedema followed emergence because of a reduction in central venous pressures and a decrease in preload which led to transient dynamic obstruction. Treatment with beta adrenergic blockade...

OBJECTIVE To evaluate the role of ballistic ureteroscopic lithotripsy in children with ureteral stones. MATERIALS AND METHODS Children under 14 years with ureteral stones were treated with ureteroscopy in a 5-year period in our institution. RESULTS Twenty-three procedures were performed in 20 children. Mean surgical time, age and stone size were 31 min. (15 - 120 min.), 11 years. (4-13 year...

Endoscopy is widely accepted as the first treatment option in the management of bile duct stones. In this review we focus on the alternative endoscopic modalities for the management of difficult common bile duct stones. Most biliary stones can be removed with an extraction balloon, extraction basket or mechanical lithotripsy after endoscopic sphincterotomy. Endoscopic papillary balloon dilation...

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 The purpose of this clinical study is to assess the safety and efficiency of a novel lithotripsy method for endoscopic treatment of urinary stones throughout the urinary tract via semi-rigid and flexible endoscopes. This new method is based on the transfer of nanosecond high voltage electric pulses to the stones through flexible probes of various sizes. METHODS The study involved 879 ...

PURPOSE To re-evaluated the clinic efficacy of ureteroscopic lithotripsy (URS) and extracorporeal shock wave lithotripsy (ESWL) on ureteral calculi with Cochrane systematic reviews in this paper. METHODS We searched clinical randomized controlled trials and prospective controlled trials in databases such as Cochrane library, Medline, Springer, Elsevier Science Direct, PubMed. Pooled estimate ...
