Treatment of urinary stones using modern urological techniques
What is urinary stone surgery?
Urinary stone surgery encompasses all the techniques used to remove or fragment stones located in the kidney, ureter, or bladder when they cannot be eliminated spontaneously. These procedures are chosen based on the size, location, and composition of the stone, as well as the patient’s anatomy. Dr. Sébastien Dominique , a urologist in Paris, offers comprehensive and personalized care for urinary stones, favoring minimally invasive approaches that allow for rapid recovery and effective results.

What are the main interventions?
Ureteroscopy (rigid or flexible): An endoscopic method performed through the natural urinary tract. It allows visualization of the stone, its fragmentation with a laser, and its extraction without incision. Laser lithotripsy (Holmium or Thulium): The gold standard technique for pulverizing urinary stones, regardless of their hardness. The laser fragments the stones into very fine particles, which are then passed naturally or removed using a basket. Percutaneous nephrolithotomy (PCNL): Indicated for large or complex kidney stones (> 2 cm). It involves creating a tiny access point in the flank to directly reach the stone. Bladder surgery for bladder stones: Used when bladder stones are too large to be treated by simple endoscopy.
When is surgery necessary?
– Stones too large to pass spontaneously – Severe pain or repeated renal colic – Ureteral obstruction – Associated infection or risk of infection – Failure of extracorporeal shock wave lithotripsy (ESWL) – Recurrent or very dense stones – Unfavorable anatomy preventing other treatments Advantages of modern techniques Minimally invasive approaches, often without incision Rapid recovery and short hospital stay High effectiveness on the majority of stone types Less post-operative pain Precise access to difficult areas of the kidney and ureter Low risk of complications when performed by a specialist After the procedure Depending on the technique used, the post-operative course may include: moderate discomfort or blood in the urine for a few days sometimes the placement of a ureteral stent (double J) Imaging to check for the absence of residual fragments Dr. Sébastien Dominique provides close follow-up to prevent recurrence and optimize long-term management.

FAQ – Frequently Asked Questions
What techniques exist for treating urinary stones?
Three main approaches: extracorporeal lithotripsy (shock waves through the skin), ureteroscopy with laser fragmentation via natural pathways, and percutaneous nephrolithotomy (PCNL) for large kidney stones.
How do we choose the appropriate technique?
The choice depends on the size, position, and hardness of the stone (assessed by the scan), as well as your anatomy. Small ureteral stones are treated with laser ureteroscopy; kidney stones larger than 2 cm are treated with percutaneous nephrolithotomy (PCNL).
Do all the calculations need to be performed?
No. A small stone less than 5 to 6 mm has a good chance of passing spontaneously with hydration and supportive treatment. Surgery is reserved for stones that are painful, obstructive, infected, or too large to pass on their own.
How to prevent the recurrence of kidney stones?
Recurrence affects one in two patients within 5 years without prevention. Drinking at least 2 liters of water per day, adapting one’s diet according to the type of stone (systematic analysis), and correcting metabolic abnormalities identified by the assessment significantly reduce this risk.
