Imaging Studies I: Kidney, Ureter, and Bladder Studies

96
Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Area of Science:

  • Urology
  • Surgical Oncology
  • Medical Imaging

Background:

  • Robot-assisted partial nephrectomy (RAPN) is complex and carries risks.
  • Effective preoperative planning and intraoperative guidance are crucial for optimal RAPN outcomes.

Purpose of the Study:

  • To evaluate the impact of 3D model reconstructions for preoperative planning and intraoperative guidance on RAPN perioperative outcomes.
  • To assess if 3D-guided RAPN improves patient safety and surgical results compared to standard RAPN.

Main Methods:

  • Retrospective analysis of RAPN cases from a French kidney cancer network database (UroCCR).
  • Comparison between 3D-Image guided RAPN (3D-IGRAPN) and a control group using propensity-score matching.
  • Analysis of perioperative outcomes including complication rates, renal function (eGFR variation), and trifecta achievement.

Main Results:

  • After matching, 3D-IGRAPN showed a significantly lower rate of major complications (3.8% vs. 9.5%).
  • Patients undergoing 3D-IGRAPN experienced a smaller decrease in estimated glomerular filtration rate (eGFR) (-5.6% vs. -10.5%).
  • The trifecta achievement rate (negative margins, no major complications, and preserved renal function) was higher in the 3D-IGRAPN group (55.7% vs. 45.1%).

Conclusions:

  • Utilizing 3D kidney reconstructions for preoperative planning and intraoperative guidance in RAPN significantly lowers complication risks.
  • This advanced planning approach improves key perioperative clinical outcomes, including renal function preservation and trifecta achievement.
  • 3D-guided RAPN represents a valuable advancement for complex partial nephrectomy procedures.
