Percutaneous removal of kidney stone(s)

Patient information

What is the evidence base for this information?

This leaflet includes advice from consensus panels, the British Association of Urological Surgeons, the Department of Health and evidence based sources; it is, therefore, a reflection of best practice in the UK. It is intended to supplement any advice you may already have been given by your Urologist or Nurse Specialist as well as the Surgical team at Addenbrooke’s. Alternative treatments are outlined below and can be discussed in more detail with your Urologist or Specialist Nurse.

What does the procedure involve?

Disintegration and extraction of kidney stones with a telescope placed into the kidney through a small puncture in the back. This usually includes cystoscopy, x‑ray and ultrasound screening.

What are the alternatives to this procedure?

External shock wave treatment, open surgical removal of stones, observation and telescopic laser destruction.

puncture track and telescope to kidney

What should I expect before the procedure?

If you are taking blood thinning medication on a regular basis, you must discuss this with your Urologist because these drugs can cause increased bleeding after surgery. There may be a balance of risk where stopping them will reduce the chances of bleeding, but this can result in increased clotting, which may also carry a risk to your health. This will, therefore, need careful discussion with regard to risks and benefits.

You will usually be admitted on the same day as your surgery. You will normally undergo pre-assessment on the day of your clinic or an appointment for pre-assessment will be made from clinic, to assess your general fitness, to screen for the carriage of MRSA and to perform some baseline investigations. After admission, you will be seen by members of the medical team which may include the consultant, junior Urology doctors and your named nurse. An x‑ray may be taken in advance of surgery to confirm the position of your stone(s).

You will be asked not to eat or drink for six hours before surgery and, immediately before the operation, you may be given a pre-medication by the anaesthetist which will make you dry-mouthed and pleasantly sleepy.

If you are admitted on the day before surgery, you will normally be given antibiotics into a vein to prevent any infection at the time of surgery.

Please be sure to inform your Urologist in advance of your surgery if you have any of the following:

  • an artificial heart valve
  • a coronary artery stent
  • a heart pacemaker or defibrillator
  • an artificial joint
  • an artificial blood vessel graft
  • a neurosurgical shunt
  • any other implanted foreign body
  • a prescription for warfarin, aspirin, rivaroxaban, dabigatran, apixaban, edoxaban or clopidogrel, ticagrelor or blood thinning medication
  • a previous or current MRSA infection
  • high risk of variant CJD (if you have received a corneal transplant, a neurosurgical dural transplant or previous injections of human derived growth hormone)

What happens during the procedure?

Normally, a full general anaesthetic will be used and you will be asleep throughout the procedure.

You will usually be given injectable antibiotics before the procedure, after checking for any allergies.

The operation is usually carried out in a single stage. First, a small tube is inserted up the ureter into the kidney by means of a telescope passed into the bladder. The operation may be carried out either with you lying on your back or you may be turned on to your face and a puncture track into the kidney is established, using x‑ray and ultrasound guidance. Finally, a telescope is passed into the kidney and the stone(s) extracted or disintegrated. A catheter is usually left in the bladder at the end of the procedure together with a temporary drainage tube in the kidney which may be internal (ureteric stent) or external (nephrostomy).

It may be necessary to puncture the kidney at more than one site if you have many stones scattered throughout the kidney.

What happens immediately after the procedure?

On the day after surgery, a further x‑ray may be performed to assess stone clearance. If a nephrostomy tube has been inserted this will be clamped over the next 24-36 hours depending on your progress. If you remain well this tube will be removed. There is often some leakage from the kidney tube site for 24 to 48 hours. Occasionally, it may be necessary to perform an x‑ray down the kidney drainage tube (nephrostomy), if inserted, using contrast medium. If the x‑ray is satisfactory, the tube in your kidney and the bladder catheter will be removed.

If a stent has been inserted this is often removed using a telescope under local anaesthetic through the bladder 2 or 3 weeks later.

The average hospital stay is one to three days.

Are there any side effects?

Most procedures have a potential for side effects. You should be reassured that, although all these complications are well recognised, the majority of patients do not suffer any problems after a urological procedure.

Please use the check boxes to tick off individual items when you are happy that they have been discussed to your satisfaction:

Common (greater than one in 10)

☐ Temporary insertion of a bladder catheter and ureteric stent/ kidney tube needing later removal

☐ Transient blood in the urine

☐ Transient raised temperature

☐ Stent related symptoms if inserted ( pain in the kidney on passing urine, frequent urination and blood in the urine)

Occasional (between one in 10 and one in 50)

c Occasionally more than one puncture site is required

c No guarantee of removal of all stones and need for further operations

c Recurrence of new stones

c Failure to establish access to the kidney resulting in the need for further surgery

Rare (less than one in 50)

☐ Severe kidney bleeding requiring transfusion, embolisation or at last resort surgical removal of kidney.

☐ Damage to lung, bowel, spleen, liver requiring surgical intervention.

☐ Kidney damage or infection needing further treatment

☐ Over absorption of irrigating fluids into blood system causing strain on heart function

What should I expect when I get home?

When you leave hospital, you will be given a discharge summary of your admission. This holds important information about your inpatient stay and your operation. If, in the first few weeks after your discharge, you need to call your GP for any reason or to attend another hospital, please take this summary with you to allow the doctors to see details of your treatment. This is particularly important if you need to consult another doctor within a few days of your discharge.

When you get home, you should maintain good fluid intake of 2-3 litres to flush your system through and minimise any bleeding. You should aim to keep your urine permanently colourless to minimise the risk of further stone formation.

It may take at least two weeks to recover fully from the operation. You should not expect to return to work within 10 days, especially if your job is physically strenuous.

What else should I look out for?

If you develop a fever, severe pain on passing urine, inability to pass urine or worsening bleeding, you should contact your GP immediately. Small stone fragments may also pass down the ureter from the kidney, resulting in renal colic; in this event, you should contact your GP immediately.

Are there any other important points?

You can prevent further stone recurrence by implementing changes to your diet and fluid intake. If you have not already received a written leaflet about this, contact your named nurse, the specialist nurse in outpatients or your consultant.

Driving after surgery

It is your responsibility to ensure that you are fit to drive following your surgery.

You do not normally need to notify the DVLA unless you have a medical condition that will last for longer than three months after your surgery and may affect your ability to drive. You should, however, check with your insurance company before returning to driving. Your doctors will be happy to provide you with advice on request.

Privacy & dignity

Same sex bays and bathrooms are offered in all wards except critical care and theatre recovery areas where the use of high-tech equipment and/or specialist one-to-one care is required.

Hair removal before an operation

For most operations, you do not need to have the hair around the site of the operation removed. However, sometimes the healthcare team need to see or reach your skin and if this is necessary they will use an electric hair clipper with a single-use disposable head, on the day of the surgery. Please do not shave the hair yourself or use a razor to remove hair, as this can increase the risk of infection. Your healthcare team will be happy to discuss this with you.
