What Happens in Laser DVIU?
- Anesthesia – The procedure is generally done under spinal or general anesthesia for a painless experience.
- Insertion of Urethroscope – A thin endoscopic camera (urethroscope) is gently inserted into the urethra. This allows the surgeon to see the exact site and length of the stricture.
- Use of Laser – Once the narrowed segment is identified, a laser beam (commonly Holmium or Thulium laser) is used to make precise cuts in the scar tissue that is blocking the urethra.
- Restoring the Passage – These cuts help to widen the urethral lumen, allowing urine to pass smoothly again.
- Catheter Placement – A temporary urinary catheter is placed for a few days to allow proper healing and prevent the urethra from closing again.
When is Laser DVIU Recommended?
- Short-segment urethral strictures (usually less than 1.5–2 cm).
- Patients with recurrent urinary retention or weak urine flow due to stricture.
- Those experiencing frequent urinary tract infections (UTIs) because of poor bladder emptying.
- Patients who prefer a minimally invasive alternative to open reconstructive urethroplasty.
Advantages of Laser DVIU
- Minimally Invasive – No external cuts or stitches.
- High Precision – The laser allows controlled incision, minimizing damage to surrounding tissues.
- Minimal Bleeding – Laser cauterizes small blood vessels while cutting.
- Short Hospital Stay – Most patients are discharged within 24–48 hours.
- Faster Recovery – Patients usually resume daily activities within a week.
- Repeatable – If strictures recur, the procedure can be repeated.
Postoperative Recovery & Care
- A catheter is usually kept for 3–7 days.
- Patients may feel mild burning or frequency of urination for a few days after catheter removal.
- Drinking plenty of fluids helps in faster healing.
- Regular follow-ups are essential because urethral strictures can sometimes recur.
Limitations of Laser DVIU
- Best results are seen in short strictures; long or dense strictures may require open surgery.
- There is a possibility of recurrence, and in some cases, multiple procedures may be needed.
