Other imaging findings

Other investigations might be used to diagnose pyonephrosis are:

Renal nuclear scanning

  • Renal nuclear scanning aids in determining the functionality of the involved kidney after the infection has resolved.
  • Consequently, this diagnostic modality is not a part of initial diagnostic workup of pyonephrosis.
  • Defects in the uptake of the radionuclide indicate irreversible damage to the renal cortex.
  • Nonfunctional kidney even after treatment of the underlying cause such as, obstruction, demands nephrectomy to prevent recurrence of pyonephrosis.


Antegrade nephrostography

  • To determine the cause of the obstruction contributing to pyonephrosis for definitive treatment.
  • Invasive procedure
  • Deferred until patient is hemodynamically stable, on antibiotic treatment and 1-2 weeks past drainage of the pus and placement of nephrostomy tube.
