Monitoring intrarenal pressure during ureteroscopy to make informed, clear decisions

The need for intrarenal pressure (IRP) monitoring

Fluid irrigation during flexible ureteroscopy is necessary to improve visibility and distention of the upper urinary tract. This can lead to elevated IRP with potential post-operative complications.

Complications of elevated IRP may include: 

  • Pain
  • Fever
  • Renal damage and pathological changes
  • Infection
  • Systemic inflammatory response syndrome
  • Sepsis
  • Fluid absorption
  • Pyelovenous backflow

 

The higher the IRP, the higher the concern for patient safety

Expert consensus on high intrarenal pressure during ureteroscopy: A pan-European Delphi panel.

In 2024, a Delphi panel of 11 physicians was conducted to help identify the patients most at risk of developing post-op complications due to high intrarenal pressures.

11 consensus statements were voted on, covering topics such as:

The definition of high IRP –

opinions initially varied on what constituted a high IRP, with concern noted predominantly at an IRP ≥80 cm H2O.
