Other imaging findings
Other investigations that 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.[1]
- Consequently, this diagnostic modality is not a part of the initial diagnostic workup of pyonephrosis.
- Defects in the uptake of the radionuclide indicate irreversible damage to the renal cortex.[2]
- 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 the patient is hemodynamically stable, on antibiotic treatment, and 1-2 weeks past drainage of the pus and placement of nephrostomy tube.[3]
