STUDY OBJECTIVE To compare extracorporeal shock wave lithotripsy and percutaneous nephrolithotomy for efficacy in treating renal calculi. DESIGN Non-randomised multicentre cohort study with 3 month follow up and 13 month data collection period. SETTING Lithotripter centre in London, tertiary referral hospital, and urological clinics in several secondary and tertiary care centres. PATIENTS...

We present a previously undocumented complication of dystrophic calcification of the prostate after cryotherapy. An 87-year-old male presented with recurrent lower urinary tract infections and was found to have an obstructing large calcified mass in the right lobe of the prostate. Subsequently, he underwent transurethral resection of the prostate (TURP) and bladder neck with laser lithotripsy t...

PURPOSE We determined the incidence of infectious complications (asymptomatic bacteriuria, urinary tract infection and urosepsis) in patients without associated risk factors treated with extracorporeal shock wave lithotripsy. MATERIALS AND METHODS We performed an observational, prospective cohort study between October 2010 and June 2013. We included all patients without risk factors who were ...

A 75-year-old woman with hypertension presented with acute suppurative cholangitis. Chest radiography revealed severe kyphosis. Abdominal computed tomography revealed a large stone impacted in the common bile duct (CBD). The patient underwent emergent endoscopic retrograde cholangiopancreatography, and cholangiography revealed a large stone (7×3 cm) in the CBD that could not be captured using a...

BACKGROUND Pyelocaliceal calculi flexible ureteroscopic approach raises problems related to operative time, associated morbidity and costs, especially by potential endoscope damage. METHODS 5 series, each of 20 patients with single pyelocaliceal lithiasis, were analyzed: Group I with calculi 1 cm fragmented to dust, Group II with calculi 1 cm with lithotripsy in fragments, Group III with calc...

BACKGROUND Bouveret's syndrome is an unusual presentation of duodenal obstruction caused by the passage of a large gallstone through a cholecystoduodenal fistula. Endoscopic therapy has been used as first-line treatment, especially in patients with high surgical risk. CASE PRESENTATION We report a 67-year-old woman who underwent an endoscopic attempt to fragment and retrieve a duodenal stone ...

Dystrophic calcification can be defined as a calcification that occurs in degenerated or necrotic tissue. It is associated with multiple clinical conditions, such as collagen vascular diseases. It involves the deposition of calcium in soft tissues despite no generalized disturbance in the calcium or phosphorus metabolism, and this is often seen at sites of previous inflammation or damage. Potas...

A 58-year-old woman presented with a 4 cm obstructing choledocolith within the proximal common bile duct. She had an extensive operative history resulting in common bile duct to jejunum anastomosis after cholecystectomy. Endoscopic retrograde cholangiopancreatography (ERCP) removal was unsuccessful, and surgical exploration was contraindicated due to multiple comorbidities. Interventional radio...

advancing an access sheath into the transplant ureter, a Storz Flex-X2 fiber optic flexible ureteroscope was used to access the collecting system over one of the wires. A 365-micron holmium laser fiber was used to fragment the stone into small pieces. The largest stone fragments were extracted using a basket, however due to the lack of an access sheath to assist in passing the ureteroscope in a...
