Renal and ureteral pathology are commonly encountered on abdominal CT,many of which require urologic intervention.The interventions of the upper tract of the GU system include nephrectomy, nephroureterectomy,extracorporeal shock wave lithotripsy,percutaneous nephrolithotomy and procedures requiring percutaneous renal or ureteral access.Understanding the clinical indications for these procedures,the key preoperative findings relevant to the Urologist,and the expected postoperative changes is essential for patient management and appropriate diagnosis.The purpose of this exhibit is to: 1.Describe the most commonly encountered interventions of the upper GU tract and their indications.2. Discuss the relevant preoperative radiologic findings important to the Urologists.3. Review the normal and abnormal post-operative imaging appearance of these interventions.

1.Optimal imaging technique for evaluating the upper GU tract 2.Clinical Indications,relevant preoperative imaging findings,and normal post-operative appearance of: -Nephrectomy -Nephroureterectomy -ESWL/ PNL -Percutaneous nephrostomy access and stent placement 3.Abnormal post-operative findings: -Fluid collections: hematoma, urinoma, abscess, hemostatic agent -Lymphatic disruption -Infection -Vascular compromise, pseudoaneurysm -Ureteral injury -Recurrent tumor
