AI Article Synopsis

  • Percutaneous nephrolithotomy (PCNL) was revolutionary for stone disease treatment, with the single stage dilator (SSD) emerging in the 1980s as a key tool now essential for mini PCNL.
  • The study outlines the development of the SSD and addresses its impact on track dilation methods, debunking misconceptions about its origins.
  • Over the past few decades, renal surgery has dramatically shifted from invasive procedures to minimally invasive techniques, with the SSD being a significant contributor to this evolution.

Article Abstract

Introduction: Percutaneous nephrolithotomy (PCNL) was described in the 1980s and revolutionized the treatment of stone disease. The crucial component to this surgery is satisfactory track creation. We examine how the development and production in the 1980s of a single stage dilator (SSD) subsequently modified for pediatric PCNL has become the ideal access tool for mini percutaneous nephrolithotomy (mPCNL) today.

Materials And Methods: The conception, production, scientific and clinical development of the original SSD is described. The pitfalls of track dilation in general according to method of dilation are also discussed and outlined.

Results: This study provides evidence clarifying commonly held misconceptions about the origin of SSD which is the mainstay of the mPCNL technique.

Conclusions: Percutaneous renal surgery continues to evolve. In less than 40 years stone surgery has transformed from a morbid open operation to a number of minimally invasive, routine techniques. The SSD has been an innovation that has played a crucial role in this change.
