Ureteroscopy and Laser Stone Removal
The Key Things to Know:
A Ureteroscopy with laser stone removal is a minimally invasive procedure used to treat kidney and ureteric stones. A small telescope (ureteroscope) is passed through the urethra and bladder into the ureter, where a laser is used to fragment or remove stones. It avoids the need for open surgery and is one of the most common and effective treatments for urinary stones.
What It Is
Under general anaesthetic, a thin telescope (ureteroscope) is inserted via the urethra into the bladder and up the ureter to the stone. A laser fibre is then used to break the stone into tiny fragments, which may be removed with a small basket or left to pass naturally. In most cases, a soft internal stent (a temporary drainage tube) is placed to keep the ureter open and aid healing.
When It's Needed
Ureteroscopy is performed when: - Stones are too large to pass naturally - Pain, infection, or obstruction is present - Shockwave lithotripsy (ESWL) has failed - Stones are located in the ureter or kidney and causing symptoms.
Surgery Diagram
Benefits
No skin incision - all done via natural passage
High success rate (>90%) for stone clearance
Day procedure with fast recovery
Suitable for stones in the ureter or the kidney
Risks
Mild pain, urgency, or frequency from the temporary stent
Blood in urine for a few days
Urinary infection (1-3%)
Rare ureteric injury or narrowing
Possible need for repeat procedure if
fragments remain
What to Expect After Surgery
Most patients go home the same day. Mild discomfort or blood-stained urine is common for several days. If a stent is placed, you may feel flank discomfort or urinary urgency until it is removed (usually after 1-2 weeks). Drink plenty of fluids and avoid strenuous activity for 3-5 days.
FAQs
-
A temporary stent is often placed to allow healing and prevent blockage.
-
Yes. The laser targets only the stone and does not harm the surrounding tissue when used properly.
-
Most people return within a few days, depending on their comfort and job type.
