Retrograde percutaneous nephrostomy offers a safe alternative for kidney stone removal, proving effective even without prior dilation. This technique is easily learned by urologists and avoids the need for interventional radiology support.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Percutaneous nephrostomy is a key procedure for kidney stone removal.
  • Traditional antegrade techniques require specific expertise and often interventional radiology support.

Purpose of the Study:

  • To evaluate the safety and efficacy of retrograde percutaneous nephrostomy as an alternative to antegrade approaches for kidney stone removal.
  • To assess the learning curve and resource requirements for urologists performing this technique.

Main Methods:

  • Retrograde percutaneous nephrostomy puncture was performed to access the kidney for stone removal.
  • The technique was applied in cases where antegrade access was challenging or unavailable.
  • Urologist expertise in endoscopic instrumentation was leveraged.

Main Results:

  • Retrograde percutaneous nephrostomy is a safe and acceptable alternative to antegrade techniques.
  • The procedure can be performed in non-dilated collecting systems, offering potentially more accurate and less traumatic puncture.
  • The technique is easily learned by urologists and does not necessitate a skilled interventional radiologist.
  • Difficulties were encountered with large staghorn calculi and when lower urinary tract access was impossible.

Conclusions:

  • Retrograde percutaneous nephrostomy is a viable option for kidney stone management, particularly for urologists skilled in endoscopy.
  • Its advantages include applicability in non-dilated systems and reduced trauma.
  • Limitations exist for extensive staghorn calculi and obstructed lower urinary tracts, but failure does not compromise subsequent antegrade or open procedures.
