Scarless Surgery for Kidney Stones – RIRS
Scarless Surgery for Kidney Stones – RIRS
RIRS, or Retrograde Intrarenal Surgery, treats kidney stones by accessing the kidney through the urethra and bladder using a flexible ureteroscope. A laser breaks stones into fragments/dust that is removed through the urine passage only, making it ideal for stones 1-2 cm in lower kidney poles, upper ureter or complex locations.
Key Advantages
RIRS offers minimal invasiveness with no external incisions, reducing pain, bleeding risk, and hospital stay compared to PCNL. It provides high success rates (often >90%) for medium stones where ESWL fails, with faster recovery (1-2 days).
Ideal Candidates
Patients with small-to-medium intrarenal stones, anatomical challenges like narrow ureters, obesity, or bleeding disorders benefit most. It's unsuitable for stones >2 cm, favoring PCNL instead.
Procedure Overview
Under anesthesia, the scope reaches the kidney; laser fragmentation occurs with direct visualization, followed by fragment removal or basketing. Post-op, a stent may aid drainage, removed soon after
