Summary
Percutaneous nephrolithotripsy for kidney stones is generally safe. Post-procedure CT scans show minimal damage, indicating this minimally invasive technique is atraumatic for most patients.
Area of Science:
- Nephrology
- Interventional Radiology
- Medical Imaging
Background:
- Extracorporeal shock wave lithotripsy (ESWL) is the primary treatment for upper urinary tract calculi.
- Percutaneous nephrolithotripsy remains a crucial alternative for select cases.
- Interventional radiologists must maintain proficiency in percutaneous stone removal techniques.
Purpose of the Study:
- To evaluate the effects and potential tissue damage of percutaneous nephrolithotripsy.
- To assess kidney and perirenal tissue changes using CT imaging before and after the procedure.
Main Methods:
- Computed tomography (CT) scans were performed on 20 patients pre- and post-percutaneous nephrolithotripsy.
- Radiological findings were analyzed to identify abnormalities in renal and perirenal tissues.
Main Results:
- Most patients (post-procedure) showed a low incidence of significant renal abnormalities when no complications occurred.
- Common findings included thickening of pararenal fascia (8 patients) and irregular renal outline (10 patients).
- Other findings: pyelo-ureteral edema (5), thickened perinephric septa with retained fragments (3), perirenal hematomas (2), subcapsular fluid (1), and urinoma with pelvic laceration (1, with technical issues).
Conclusions:
- Percutaneous nephrolithotripsy is a generally atraumatic procedure for kidney stone removal.
- CT imaging reveals minimal significant abnormalities in most cases, supporting the safety of the technique.
