Overview
Medical therapy
- Pyonephrosis is a urological emergency.[1]
- Hemodynamically unstable patients may require aggressive fluid resuscitation with crystalloids and pressor agent (dopamine) to maintain adequate blood pressure.
- Before initiating antimicrobial treatment for suspected pyonephrosis, urine and blood culture and susceptibility test should always be performed.
- All patients with pyonephrosis should be empirically treated with intravenous long-acting, broad-spectrum antibiotics which may be later narrowed based on culture report.
- Presence of pyonephrosis and obstruction reduces the efficacy and penetration of antibiotics. Therefore, drainage of the pus should be done immediately after administering the antibiotics.
- Intravenous Ampicillin + Gentamicin is a good initial option that covers both gram-positive and negative organisms.
- Anaerobic coverage with clindamycin, antifungal, or antitubercular agents may be required depending upon the clinical scenario.
- Carbapenem-resistant enterobacteriaceae can be treated with ceftazidime-avibactam, ceftolozane-tazobactam[2], meropenem-vaborbactam[3], and imipenem-cilastatin-relebactam.[4][5]
- After treating the infection, additional investigations are required to find the cause of the obstruction e.g., nephrolithiasis, tumors etc. for definitive treatment.
