Abstract
BACKGROUND:
Core Needle Biopsy involves introducing large hollow needle through the skin to collect a tissue for investigation. It’s become a well-established method as the standard sampling procedure. It’s a relatively safe, minimal invasive procedure with diagnostic accuracy comparable to open surgical biopsy.
AIM OF STUDY:
Assess the accuracy and safety of core needle biopsy in diagnosis of renal and suprarenal tumors.
METHODS:
This is a prospective interventional study. Core needle biopsy was done for 42 patients; 38 patients were included. Biopsy done by activation of needle biopsy device that introduced into the tumor under ultrasound guidance and collection of sample.
RESULTS:
Wilms tumor was positive in 71.1 % (n=27), 23.6 % (n=9) were neuroblastoma and 5.3 % (n=2) were non-conclusive. Only 18.4% (n=7) developed hematuria while intra-abdominal bleeding was not observed in any patient. For Wilms tumor the sensitivity is 93.1 % and the specificity is 100 % and diagnostic accuracy is 94.7 %. The sensitivity, specificity and diagnostic accuracy for neuroblastoma are 100 %.
CONCLUSION:
It is a simple, safe and efficient method for diagnosing renal and suprarenal tumors, complications occur infrequent, and most are easily treated or self-limiting.
