Ureteric Calculi

The Diagnosis and Treatment of Ureteric Calculi.

Pulsed dye laser lithotripsy for ureteric calculi.

Laser has proven to be an effective and safe method of treating ureteral stones. When the electromagnetic energy of a laser pulse is selectively absorbed by stone, a plasma fonns at the surface. This plasma, which is composed of ions and electrons, continues to absorb laser energy reaching very high pressure and generating a shock wave that fragment the stone. The degree of stone fragmentation ...

Variation of ureteric jet characteristics according to size and site of ureteric calculi

Colour Doppler ultrasound scan has a recognized place in evaluation of patients with ureteric calculi. The purpose of this study was to assess the ureteric jet characteristic variations according to size and site of ureteric calculi. This descriptive study was conducted using 83 patients with suspected calculus disease, aged 20-60years, who presented to genitourinary clinic, Teaching Hospital P...

Laser lithotripsy for ureteric calculi: results in 250 patients.

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...

Submucosal migration of ureteric calculi: related to ESWL?

Three patients were reinspected by ureteroscopy after repeat ESWL. Ureteroscopy initially did not disclose an intraluminal stone and only visualized a severe inflammatory reaction of the ureteric wall and a boss of the ureter at the level of the fluoroscopically suspected stone location. An intact stone in all 3 cases was finally exposed by tactile contact at the top of the ureteroscope after p...
