Laser treatment for kidney stones: what to know

A urologist usually passes a small scope through the urinary passage to reach the stone. Laser energy fragments the stone, and instruments or irrigation may help remove the pieces. The approach depends on the stone's size, position and hardness, as well as your urinary tract and general health. A temporary stent may be placed to support drainage while swelling settles; it can cause urinary urgency, discomfort or blood-tinged urine. Kidney stones can cause flank pain, abdominal pain, painful urination or difficulty passing urine, but symptoms vary.

Your care team will explain fasting, medicines, anaesthesia and whether a stent is planned. Follow the discharge instructions, take prescribed medicines as directed and drink fluids if your clinician says this is suitable. Strain or collect stone fragments only if requested, because analysis can help guide prevention. Avoid strenuous activity until you are told it is safe. A GP Consultation can help coordinate assessment, while an Abdominal Ultrasound may be used to look for obstruction or monitor the urinary tract; it does not replace specialist planning in every case.

Seek urgent help for fever or chills with urinary symptoms, severe or worsening flank pain, repeated vomiting, inability to pass urine, heavy bleeding, fainting or breathing difficulty. Contact the treating team if pain is not controlled, a stent causes significant symptoms, or you are unsure whether a fragment has passed. Infection behind a blocked urinary tract can become serious, so fever with poor urine flow should not be watched at home. Dehydration can worsen weakness and urinary concentration; follow the fluid plan provided for you.

Ask why laser treatment is recommended, where the stone is, whether a stent is likely, how fragments will be checked, what activity and fluid advice applies, and who to contact if symptoms worsen.
