Ureteroscopy: Overview of the procedure

The procedure with its inhert simplicity and precise nature can remove stones in ureter in all the parts of ureter.

The three parts namely upper, mid and lower ureteric stones behave differently when fragmented with laser. The ureteroscope reaches the stone and pulverizes the stone to small particles below 3 mm.

This action is continuously monitored on the monitor and hence the urologist can control his actions accordingly. The procedure is human operated and therefore is dependent on the expertise of the urologists.

How to choose your treatment?

Its worthwhile to note that all urologists are not choosing all the laser techniques available the reason being

  • The cost of fixed laser equipment
  • Running cost of fibreoptic in each procedure
  • Expertise of the urologist

Patient selection and suitability...

URS or ureteroscopy ideally is best suited for stones upto 17 mm in mid and lower ureter.

Higher up located stones that is in upper ureteric region either get pushed to inside of the renal region or the the fragmentation energy is not enough to completely convert the stone to sediments.

For the upper ureteric stones the technology is called RIRS.

How safe is the procedure of ureteroscopy?

In the hands of an experienced urologist the technique is a boon to avoid open surgery and remove the ureteric stone with almost nil complications.

This technology uses a ureterscopy tube which has a light source and a camera attached to its tip.

This is passed through the normal urinary passage and is used to reach upto the stone in ureter.

After coming in contact with the stone ,laser is passed to pulverise the hard stone into particle form and is taken out in smaller particle form.

This technology is used for stones in ureteric or urinary bladder region.

No cut is given anywhere as natural urinary passage is used.

Success rate of ureteroscopy: an overview

For stones found in the three parts of ureter, ureteroscopy is the best option as it is does not involve any trauma or cut in the body.

Secondly the stone removal is a single step procedure unlike ESWL.

The whole procedure is done under a a camera guidance and hence the results are closely monitored and verified.

The most approachable is the lower most part of ureter and here the success rate is highest 95to 98%.

In rare cases when the ureteral passage is very narrow or is stenosed by a stricture or a fold, the procedure might have to be abandoned due to poor or difficult passage of ureteroscope.

It is therefore advised to have a clearance by IVP and be sure of the passage.

Chances of poor outcome in cases of ureteroscopy.

When the stone is big more than 22 mm to 30 mm, it might be a cumbersome process to get all the contents out in a short time. Other options should be planned in such cases.

When the stone is higher in the ureter, the chances of it being pushed back to kidney are high. In such a case flexible ureteroscopy with holmium is very effective.
