The Randomized Comparison of Two Different Endoscopic Techniques in the Management of Large Bladder Stones: Transurethral Use of Nephroscope or Cystoscope?

Abstract

Treatment of large bladder stones by transurethrally placed nephroscope is a fast and effective treatment modality compared to endoscopic treatment via cystoscope. Nephroscope allows for use of larger forceps and facilitates collection of large stone fragments through its 24F sheath. It also prevents multiple entries to the urethra and hence avoids possible urethral injury. Combined pneumatic/ultrasonic lithotripsy device, with its aspiration quality, enables the surgeon to gain a better endoscopic view during both procedures.
