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.
