Abstract

PURPOSE: To assess the ability of scrotal Doppler ultrasonography to confirm the diagnosis of clinical varicoceles and detect subclinical varicoceles. MATERIALS AND METHOD: Sixty patients with clinically evident varicocele were examined by scrotal doppler ultrasonography(gray scale: 60 patients, spectral Doppler: 35 patients, color Doppler: 22 patients). A control group of 21 patients with no suspected scrotal pathology also were studied. The age range of the varicocele group was 12-49 years. The normal group consisted of 21 subjects aged 19-23 years. Ultrasonographic measurement of scrotal vein diameter of patients before and during Valsalva maneuver, and scrotal vein blood flow reversal with Valsalva maneuver was compared with the findings of varicocele by physical examination.
RESULTS
Significant differences were found in scrotal vein diameter before and during Valsalva maneuver between normal and varicocele testicular units. Cut-off points were selected in an arbitrary fashion on the basis of scattergram. Using this cut-off points and blood flow reversal, we found that 12(23%) of 53 patients with a clinically palpable left unilateral varicocele had an ultrasonographically positive subclinical right varicocele. 8(38%) of 21 patients without a clinical varicocele had a positive scrotal ultrasound.
CONCLUSIONS
We suggest that scrotal doppler ultrasonography is a reliable means of confirming the clinical varicocele and screening the subclinical varicoceles.
