The technique is particularly well-suited to stones smaller than 2 cm; for larger stones, several sessions or a percutaneous approach may be considered."},{"question":"How does the procedure unfold?","answer":"The procedure is performed under general anesthesia, most often on an outpatient basis, without any incision. A JJ stent is sometimes left in place for a few days to protect the kidney while the fragments are being removed."},{"question":"What are the usual consequences?","answer":"Burning during urination, pinkish urine, and discomfort related to the JJ stent are common and temporary.

This method allows for the fragmentation of stones with a laser<\/strong> , without incision, without scarring<\/strong> , and with a rapid recovery. Dr. S\u00e9bastien Dominique<\/strong> , a urologist in Paris, uses the most advanced laser technologies (Holmium and Thulium) in the treatment of stones, for personalized<\/strong> , safe<\/strong> , and effective<\/strong> care.

What is laser lithotripsy?<\/h4> Laser lithotripsy involves introducing a miniature camera (ureteroscope or nephroscope)<\/strong> into the urinary tract, through the natural pathways<\/strong> (urethra, bladder, ureter), up to the stone.
  • A laser fiber<\/strong> is then used to pulverize or fragment the calculus<\/strong> .<\/li>
  • The fragments are either eliminated naturally through urine, or extracted using forceps or endoscopic baskets.<\/li>
  • This is a treatment without surgical incision<\/strong> . No stitches or visible scarring.<\/li><\/ul>

    Indications<\/strong><\/h2> Laser lithotripsy is indicated in several situations:
    • Symptomatic kidney<\/strong> or ureteral<\/strong> stones (pain, renal colic, obstruction)<\/li>
    • Failure of medical treatment<\/strong> or spontaneous expulsion<\/li>
    • Calculations too large<\/strong> to be eliminated on their own (generally > 6 mm)<\/li>
    • Recurrent kidney stones<\/strong><\/strong><\/li>
    • Contraindication to extracorporeal shock wave lithotripsy (ESWL)<\/strong><\/strong><\/li>
    • Bladder stones<\/strong> accessible endoscopically<\/li><\/ul>

      <\/h2>

      Holmium and Thulium Lasers: Two Complementary Technologies<\/strong><\/h2> The Holmium:YAG laser<\/strong> is the most widely used in urology for stone fragmentation. It is effective on all types of stones<\/strong> (hard, soft, mixed), regardless of their location. It allows for a choice between:
      • Fragmentation<\/strong> (into easily extracted pieces)<\/li>
      • Dusting<\/strong> : spraying into a fine dust that is naturally eliminated.<\/li><\/ul> The Thulium laser<\/strong> (a newer technology) offers increased precision<\/strong> , better thermal control<\/strong> , and reduced bleeding<\/strong> . It is sometimes used depending on the surgeon's preferences and the characteristics of the stone.

        <\/h2>

        Procedure of the intervention<\/strong><\/h2>
        • Performed under general anesthesia<\/strong> (outpatient or short hospital stay)<\/li>
        • Introduction of a flexible or rigid endoscope<\/strong> through the natural openings<\/li>
        • Direct visualization of the calculation on screen<\/li>
        • Holmium or Thulium laser fragmentation<\/strong><\/strong><\/li>
        • Extraction of fragments<\/strong> if necessary<\/li>
        • Possible placement of a ureteral stent (double J)<\/strong> to facilitate drainage<\/li><\/ul> Average duration of the procedure: 30 to 90 minutes<\/strong> , depending on the number, size and location of the stones.

          Advantages of laser lithotripsy<\/strong><\/h2> Minimally invasive technique<\/strong> , without incision or scarring. Treatment possible for all types of kidney stones. Access to difficult areas (renal calyces, upper ureter) thanks to the flexible endoscope . Rapid recovery<\/strong> , little or no postoperative pain. Excellent results<\/strong> with very high success rates. Fewer complications compared to open or percutaneous surgery.","image":3444},{"acf_fc_layout":"video_section_block","eyebrow":"Expertise","title":"Academic background","text":"","video_url":"https:\/\/www.youtube.com\/watch?v=v-ETC6gAk20"},{"acf_fc_layout":"image_text_block","eyebrow":"","title":"Prevention and post-operative care","content":"Post-operative care<\/strong>
          • Release on the same day or the following day,<\/strong> depending on the circumstances<\/li>
          • Resumption of activities possible in 2 to 5 days<\/li>
          • Monitor for possible moderate pain or the presence of blood in the urine (transient).<\/li>
          • A double J tube<\/strong> can be left in place for a few days to a few weeks to prevent secondary pain or colic.<\/li>
          • A post-operative check-up<\/strong> (imaging + consultation) is systematically arranged to verify the absence of residual fragments and prevent recurrence.<\/li><\/ul> Prevention of recurrence:<\/strong> After lithotripsy, a metabolic assessment<\/strong> may be recommended to understand the origin of the stones:
              • Blood test (calcium, uric acid\u2026)<\/li>
              • 24-hour urine analysis<\/li>
