Super-Mini-PCNL (SMP)

  • Guohua Zeng

Super-mini-PCNL (SMP) is a new miniature endoscopic system consisting of an 8.0 F super-mini nephroscope and a newly designed 12 or 14 F irrigation-suction sheath. The main characteristic of the irrigation-suction sheath is to allow irrigation and suction respectively. This property increases irrigation and stone clearance despite the small instrument dimension. Several clinical studies demonstrated that the SMP technique is safe, feasible, and effective for managing moderate-sized renal calculus with the advantages of a small percutaneous tract, less blood loss, high efficacy in stone clearance, improved visual field, high totally tubeless rate, short operation duration, and ease of operating.
