EVALUATION OF SCROTAL LESIONS BY GRAY SCALE ULTRASONOGRAPHY AND COLOUR DOPPLER
Journal of Evolution of Medical and Dental Sciences
BACKGROUND Until the mid 1970's, scrotal examination was limited to palpation and transillumination. Miskin and Bain (1974) first reported the use of Ultrasonography to examine testes and scrotum. With advancement like colour Doppler, ability to assess testicular vascularity increased. Although other radiological investigations have roles in specific situations, present study was undertaken to evaluate the usefulness and accuracy of sonography and colour Doppler in scrotal abnormalities.
... normalities. Prospective study carried out in 100 patients after proper informed and written consent with inclusion criteria of 'All age patients with clinical suspicion of scrotal pathology' and exclusion criteria of 'History of operative or therapeutic procedures on the scrotum with exception of vasectomy.' These patients' scrotums were scanned in various plan on "Voluson 730 PRO" (GE Healthcare) system and LOGIC E-9 (GE Healthcare) using linear probe (As applicable) with comparison from asymptomatic side. Relevant other radiological and pathological investigations were done wherever indicated. RESULTS Majority of patients were between 21-40 years of age (62%) with commonest presenting complaint was scrotal swelling in 73%. Fluid collections were the commonest abnormality detected on sonography. Hydrocele was the most frequent fluid collection seen in 38 cases (26.3%). In acute inflammation, hypoechogenicity of the testes was most common sonographic feature. In our study, ultrasound showed 99% accuracy to distinguish between Intratesticular and Extratesticular pathology. CONCLUSIONS High-resolution USG with colour Doppler can reliably define the morphological features and vascularity of scrotal lesions. USG is highly accurate in evaluating the consistency of scrotal mass and in localizing scrotal abnormality. Ultrasound evaluation of the scrotum must include colour Doppler imaging of testis and epididymis with comparison from the asymptomatic side.
