Frequently Asked Questions

1. Which doctor should be consulted for ureteroscopy procedure?

Consult Urologist for the procedure

2. Who is an ideal candidate for ureteroscopy?

Ureteroscopy has a high success rate for lower and mid ureter stones that do not pass out spontaneously or where medical management has failed.

Stones over 5 mm in the ureter have only a 50% chances of spontaneous expulsion and will generally require ureteroscopy procedure.

3. What are the reasons for having an ureteroscopy?

If there is persistent intermittent colic or an obstructed system especially with fever, reteroscopy is advised for removal of the stone or obstruction.

4. What reduces the risk of stones in the future?

Good hydration is the key to preventing stone formation. Diet plays a smaller role in prevention. Making the urine alkaline by taking potassium citrate solution or tablets is advised for many types of stones to lower the risk of recurrence.

5. What is the success rate of ureteroscopy?

It depends on the location of the stone in the ureter.
  • For stones in the lower ureter 96% to 98% success
  • For stones in the mid-ureter 90% to 95% success
  • For stones in the upper ureter 70 to 80 success
6. Is a Basket always used in ureteroscopy?

Sometimes to remove the smaller stones after fragmentation or for removing a small stone the basket or a grasper is used.

7. What are the cases where ureteroscopy may not be a good option?

For a large hard stones in the ureter that are over 2.5 to 3 cms , other methods of stone removal maybe better.

A stone lodged in the upper ureter or just below the pelvi-ureteric junction may fly back into the kidney, hence a flexible ureteroscopy maybe a better option.

hi,i am vishal tomar 22m, my stone is 12mm in upper part of urater. tell me treatment.

My sister had stones, the ER sent her home told it would pass, 2 days later she's back in ER still in serve pain, they gave her more pain killers and sent her home. 2 days after that she's back in ER with sever pain still, each time they did CT scans. This time they tell her, her kidneys have shut down she's in failure, they admit her. 2 surgeys later she comes home. She has had serve pain in her feet and both of her legs are numb. She goes to the docter who says thats a good sign, if it dasn't go away in a few weeks he'll refer her to a Neuro Doc. She is still in terrible pain and is getting referred. My question is, when she had the surgeys could they have cut a nerve or is it damage from the acute kidney failure?
