Is fluoroscopy essential for retrieval of lower ureteric stones?

INTRODUCTION: The aim of this study was to assess the efficacy of ureteroscopy for lower ureteric stones without the use of fluoroscopy. PATIENTS AND METHODS: Between June 2001 and January 2005, a total of 110 patients with a mean age of 33.5 years (range 12-65) suffering from of lower ureteral calculi (below the upper margin of the sacroiliac joint) prospectively underwent ureteroscopic removal. Retrograde pyelography was avoided, and no safety guidewire was placed.

Whenever required, the ureteric meatus was dilated with a ureteric balloon under direct vision. Double-J stent placement was done with the aid of ureteroscopy. A fluoroscope was kept standby.

The patients had a postoperative X-ray of the kidney-ureter-bladder region to document the stone clearance. RESULTS: The mean stone size was 8.7 mm (range 6-15). Complete clearance without the use of fluoroscopy was achieved in 99 patients (94.2%).

Fluoroscopy was required in 6 patients (4%) for calcified stricture (n = 1), duplex ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
