Conclusion
The success rate of fine-needle aspiration cytology resulting in a diagnostic specimen in our study was 83,3%.
Accuracy of our study corelates with the reports in literature (>70%) (3,
5-7).
US guided fine-needle aspiration cytology is a safe,
minimally invasive diagnostic procedure.
None of our 60 patients had any reported complications.
In published literature,
reported complications of fine-needle biopsy procedures are rare,
but include perirenal hemorrhage,
pneumothorax,
infection,
arteriovenous fistula and urinoma.
Death and needle track seeding are extremely uncommon (2,
4).
The comparisment between the fine-needle aspiration cytology results and definite histology reports of our 17 cases shows a perfect,
100% match in confirming malignancy.
This corelates with some reports in published literature (2) while other reports suggest slightly lower,
73-94% accuracy (3,
5-11).
In conclusion,
our study confirmed our hypothesis that ultrasound-guided fine-needle aspiration cytology is a safe diagnostic procedure that provides valuable results completely comparable to definite histological pathology reports and as such it should have a place in the diagnostics of solid renal lesions.
