Objective: To evaluate the role of ultrasound as a sole procedure for intraoperative localisation and management of complex renal calculi.
Material And Methods: Between September 1997 and November 2001, 16 patients underwent complex surgery for multiple, large or recurrent renal stones using the ultrasound image as a the sole intraoperative diagnostic procedure. A 8.
Objective: To describe our experience with fine-needle aspiration biopsy (FNAB) of the thyroid and compare our results with direct palpation versus ultrasound scanning (USS) in an area of endemic goiter in Italy.
Methods: We considered all patients submitted to ultrasound-guided FNAB of thyroid nodules during a 10-month period at our outpatient clinic and analyzed the following: (1) clinical data (number of nodules and identification of the nodule for FNAB); (2) USS data (number of nodules and identification of the nodule for FNAB on the basis of hypoechoic pattern + blurred perinodal halo + microcalcifications or intranodal color Doppler signal indicative of blood flow); (3) cytologic specimens, categorized as suspicious, malignant, negative, or nondiagnostic; and (4) histologic final report of the cytologically positive nodules.
Results: The study group consisted of 348 female and 72 male patients who underwent FNAB of the thyroid at our institution.
