Presentation
Septic shock and renal failure.
Patient Data
Right kidney has normal appearances. Left kidney is enlarged and severely hydronephrotic.
Noncontrast CT demonstrating left-sided renal lobulated fluid attenuation masses are most likely abscesses in this context. There may also be a high-grade pelviureteric junction obstruction with an infected collecting system.
Ultrasound-guided puncture of lower pole calyx. Frank purulent material obtained from access sheath and sent for MCS. An 8.5Fr nephrostomy tube was secured in the renal pelvis. No complication encountered.
Case Discussion
This case illustrates a complicated obstructive pyelonephritis, which usually requires prompt treatment aiming to save the kidney viability. Left kidney is showing severe hydronephrosis and cortical thinning may represent a chronic long standing pelvic-ureteric junction obstruction.
