Overview
Earlier, nephrectomy was the standard treatment for pyonephrosis. However, now interventional procedures like retrograde ureteral stenting or percutaneous nephrostomy catheter placement are done for urgent decompression depending on the hemodynamic stability of the patient and some other factors like the presence of urolithiasis.
Surgery
- Prior to the 1980s, nephrectomy was the standard treatment for pyonephrosis.[1]
- Presently, interventional procedures are required to drain the pus in pyonephrosis.
- Drainage of the pus can be done through either retrograde decompression (placing a catheter in the ureter) or antegrade decompression through percutaneous nephrostomy tube placement.
- Retrograde decompression is a minimally invasive procedure that requires placement of catheter in ureters. It is performed under general anesthesia and is contraindicated in hemodynamically unstable patients. Ureteric stenting is a good option for drainage of pus.[2] A disadvantage of retrograde stenting is that if a stone of >2 cm is present chances of iatrogenic complications increase and therefore, this approach is avoided in such cases.[3]
- Percutaneous nephrostomy catheter placement (antegrade decompression) is done when the patient is hemodynamically unstable or retrograde decompression is not possible. The nephrostomy catheter is left indwelling for at least 24 hours. The advantages of this approach include direct access to the collecting system to administer medications, drainage of infected material, percutaneous chemolysis of stones.[4][5]
