Doppler sonographic findings in testicular microlithiasis

Abstract

Objective: The aim of this prospective study was to compare the resistive index (RI) values, which is a parameter of testicular parenchymal perfusion, in testicular microlithiasis (TM) cases and normal cases. Materials and Methods:Training Corps training camp were included in the study. A screening scrotal ultrasound was performed and all men diagnosed with TM underwent a scrotal Doppler ultrasonography scan (US). US examinations were performed for subjects with TM and without TM as a control group and RI was determined. Results:observed in three cases. Conclusion: -amination.

Testicular microlithiasis: Correlation with doppler sonography of testicular arteries and sperm function

“…In the normal testis, the vascular resistance of the intratesticular arteries is low with antegrade diastolic flow throughout the cardiac cycle . Some studies have proposed that the situation may be different in patients with TM as impairment of testicular perfusion may occur due to compression of intratesticular arteries by the microcalcifications . However, this hypothesis failed to materialize in those studies as well as in our study, where Doppler parameters were within normal limits in all patients with TM, including those with extensive degree of involvement.…”

More specifically, no significant differences were observed in the mean RI, Vmax, Vmin, and Vmax/Vmin between TM patients and control subjects.…”

“…Doppler US findings are regularly used to evaluate several scrotal disorders, such as varicocele, epididymo‐orchitis, and testicular infarction . However, few studies have attempted to assess the Doppler findings in TM patients . These studies have suggested that intratubular microlithiasis, particularly in extensive disease, may result in compression of intratesticular arteries, thereby altering the spectral Doppler parameters of these arteries .…”
