Miniperc surgery for kidney stones <2 cm was compared to standard and tubeless percutaneous nephrolithotomy (PNL). Miniperc showed no significant advantages and resulted in a lower stone-free rate, leading to its discontinuation.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Nephrolithiasis Treatment

Background:

  • Percutaneous nephrolithotomy (PNL) is a common procedure for kidney stone removal.
  • Miniperc, a variation of PNL, aims to reduce invasiveness for smaller stones (<2 cm).
  • Comparative effectiveness of miniperc versus standard and tubeless PNL requires evaluation.

Purpose of the Study:

  • To compare the outcomes of miniperc with standard PNL and tubeless PNL for treating renal stones smaller than 2 cm.
  • To evaluate operative time, complications, analgesic requirements, hospitalization duration, and stone-free rates.

Main Methods:

  • Retrospective analysis of 134 percutaneous treatments for renal stones <2 cm.
  • Patient groups included miniperc (n=40), standard PNL (n=67), and tubeless PNL (n=27).

  • Comparison of key clinical outcomes between the three techniques.

    • Main Results:

    • Miniperc had longer operative times than standard and tubeless PNL.
    • Miniperc demonstrated a reduced hematocrit drop and no transfusions, but a lower stone-free rate (77.5%) compared to standard PNL (94%) and tubeless PNL (100%).
    • Tubeless PNL offered the shortest hospitalization (2.18 days) and highest stone-free rate.

    Conclusions:

    • The miniperc technique did not show significant advantages over standard or tubeless PNL for stones <2 cm.
    • Higher analgesic use and lower stone-free rates were observed with miniperc compared to tubeless PNL.
    • The study concluded against the routine use of miniperc, favoring tubeless PNL when feasible.
