The objective of this study is to retrospectively evaluate factors significantly contributing to a failed stone extraction (SE) in patients with difficult to extract bile duct stones (BDS). Patients and Methods. During a 10-year period 1390 patients with BDS underwent successfully endoscopic sphincterotomy. Endoscopic SE was graded as easy; relatively easy; difficult; and failed. Difficult SE w...
Gallstone disease is one of the major surgical problems in the Libyan population; it is probably related to diet, especially excessive consumption of meat. The study was conducted to determine the composition of gallstones and their possible etiology in a Libyan population. The chemical composition of gallstones from 41 patients (six males and 35 females) was analyzed. The stones were classifie...
Nephrolithiasis is a common health problem across the globe with a prevalence of 15%-20%. Idiopathic hypercalciuria is the most common cause of nephrolithiasis, and calcium oxalate stones are the most common type of stones in idiopathic hypercalciuric patients. Calcium phosphate stones are frequently associated with other diseases such as renal tubular acidosis type 1, urinary tract infections,...
OBJECTIVE To determine a difference in the stone-free-rate among different renal locations in children after extracorporeal shockwave lithotripsy (ESWL). STUDY DESIGN A descriptive study. PLACE AND DURATION OF STUDY Urology Department, Shifa International Hospital, Islamabad, Pakistan, from January 2007 to June 2015. METHODOLOGY The study included children who underwent ESWL, divided into...
Open surgery with common bile duct (CBD) exploration and T tube drainage are still traditionally performed in a large amount of selected patients with cholelithiasis and choledocholithiasis. Confirmation of CBD clearance via T tube cholangiography after surgery is a routine procedure before T tube removal. The present study aims at investigating potential risk factors associated with residual s...
Background and study aims Endoscopic sphincterotomy plus large-balloon dilation (ES-LBD) has been reported as an alternative to endoscopic sphincterotomy for the removal of bile duct stones. This multicenter study compared complete endoscopic sphincterotomy with vs. without large-balloon dilation for the removal of large bile duct stones. This is the first randomized multicenter study to evalua...
OBJECTIVE To conduct a systematic review and meta-analysis investigating the efficacy and safety of medical expulsive therapy (MET) in low risk of bias (RoB) randomised controlled trials (RCTs). METHODS A Cochrane style systematic review was conducted on published literature from 1990 to 2016, to include low RoB and a power calculation. A pooled meta-analysis was conducted. RESULTS The MET ...
Improvement of stone comminution by slow delivery rate of shock waves in extracorporeal lithotripsy.
AIM The aim of this study was to investigate the effect of delivery rate of shockwaves (SW) on stone comminution and treatment outcomes in patients with renal and ureteral stones. METHODS Patients with radio-opaque stones in the upper urinary tract that were treated by extracorporeal shock wave lithotripsy (ESWL) were divided into two groups according to delivery rate (120 or 60 SW/min). The ...
Between May 1997 and February 1998, 40 cases of renal stones and 40 cases of ureteral stones in 60 males and 20 females were treated with the Dornier Lithotripter Compact. The size of the stones ranged from 5 mm to 80 mm. Three patients required epidural anesthesia and 4 patients required a ureteral stent. Fragmentation of the stones was observed in all patients. After 1 month, the efficacy and...
Extracorporeal shock wave lithotripsy of pancreatic stones was performed in eight patients with chronic pancreatitis and a dilated duct system harbouring stones 5 to 20 mm (means 10 (SD) 5 mm) in diameter. After endoscopic sphincterotomy of the pancreatic orifice the stones were disintegrated by shock waves under fluoroscopic control using a kidney lithotripter (Dornier HM3). The procedure was ...
