text: Pyonephrosis is a surgical emergency. Hemodynamically unstable patients may require aggressive fluid resuscitation with crystalloids and pressor agent (dopamine) to maintain adequate blood pressure. All patients with pyonephrosis should be empirically treated with intravenous long-acting, broad-spectrum antibiotics like ampicillin + gentamicin combined with urgent drainage of the pus. After treating the infection, additional investigations are required to find the cause of the obstruction e.g., nephrolithiasis, tumors, etc. for definitive treatment.
