General Information for Patients

Medical Imaging

Most Urologists will refer you for an x-ray, ultrasound or computed tomography (CT) scan in the 10 days prior to your treatment. This is to assess the position, size and type of stone and ensure that it is suitable for lithotripsy treatment.

Eating and drinking

When having a general anaesthetic/monitored sedation it is vitally important that you have an empty stomach before your procedure. This means no eating or drinking before your surgery for a time specified in your information pack.

On Arrival

On arrival at the hospital you will be shown to the day surgery unit. The nursing staff will admit you for your surgery and after that you will be seen by the urologist and anaesthetist. In some cases the urologist and anaesthetist will see you on the bus instead of the ward. They will discuss the procedure and the use of anaesthesia with you and give you an opportunity to ask any questions you may have for them. Once this is done and you feel comfortable, they will ask you to sign the consent form which means the surgery is ok to go ahead.

Your procedure

The hospital staff will come and get you when it is time for your procedure. If you want a family member to accompany you on board initially, they are welcome to do so. 

Parents or guardians are allowed to accompany a child on board, and one caregiver is allowed to stay with the child until they go off to sleep.

After surgery

After treatment you will be taken to a quiet area inside the hospital to recover. You will be given information about how to care for yourself following discharge. You will also be given a letter for you to take to your GP explaining your treatment details. Follow up imaging will be requested by your specialist to assess the effectiveness of the lithotripsy treatment. This is usually performed 2-4 weeks post treatment, and sometimes a second lot of imaging will be requested if the stone has not completely resolved in the first follow up images.

When can I go home?

You will be discharged once the doctor or nurse decides you are fit to go home. You must feel comfortable about going home so if you feel groggy or sick you do not have to go home until you feel better. A follow up appointment may be made for you in approximately 4 weeks time.

Getting home after your lithotripsy

Please ensure that you have arranged for someone to drive you home as you are not allowed to drive after anaesthesia or sedation. If you live alone you should try to stay with someone overnight, in case you feel unwell. We recommend you have an adult stay with you for 24 hours after the procedure.



Passing the stones

The stone/stones that have been treated may take a between a few days/weeks to pass and this may cause mild pain. They will pass out of the body in the urine as sand or small fragments.



Taking care after your procedure

Remember that you must not operate any machinery, drive or make any important decisions or sign any legal documents for at least the following 24 hours following your anaesthetic.

After the procedure you will be asked to drink plenty of fluids for about a week to help flush any stone fragments out of your kidneys. It is recommended that you drink at least 1 ½ - 2 litres of water over the course of the day, do not drink this all at once. You can expect bruising and tenderness at the site where the shockwaves were administered, this usually settles quite quickly. There may be an episode of bloody urine. This is not unusual but should you have any concerns consult your GP or urologist.

Be vigilant and observe yourself for signs of urinary infection: frequent passing of urine, burning in the urethra, offensive smelling urine and fever.

Observe for signs of stone obstruction: excessive loin pain, nausea, vomiting and fever. If you observe these signs consult your GP or urologist.
