Urinary Tract Calculi VI: Surgical Management

10
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

57
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Nephrolithotomy

Background:

  • Kidney stone treatment has evolved towards less invasive techniques.
  • Mini-percutaneous nephrolithotomy (mini-PCNL) represents a significant advancement in reducing surgical morbidity.

Purpose of the Study:

  • To review and summarize recent progress in mini-PCNL.
  • To highlight advancements in surgical technique, stone removal, lithotripsy, and surgical models.

Main Methods:

  • A narrative review of English-language articles published up to October 2022.
  • Searches were conducted on PubMed and Web of Science using keywords related to mini-PCNL and miniaturization.

Main Results:

  • Significant progress has been made in reducing tract size, exemplified by needle-based percutaneous nephrolithotomy.
  • Developments include enhanced robotic-assisted PCNL utilizing artificial intelligence.

Conclusions:

  • Miniaturization of PCNL necessitates strategic adjustments in access, stone removal, lithotripsy, and overall surgical approach.
  • Further large-scale prospective studies are essential to validate and optimize the safety and efficacy of mini-PCNL.
