[Value of ultrasound in microlithiasis of the testis in andrological patients].

PurposeThe objective of this retrospective study is to show the importance of sonography in andrological patients with testicular microlithiasis (TM).Patients and methods1314 male patients were seen to our andrological clinic in the course of one year. The age range of these patients was 25 to 39 years (mean age 32 years). All patients underwent testicular sonography as well as a sperm-analysis.Results284 patients showed normozoospermia without any evidence of TM. Of the remaining 1030 patients with a pathological spermiogram, 8 were shown to display more than 10 echogenic foci per transducer field in both tests. 1 patient suffering from an already palpable testicular tumor only showed, unilateral, unifocal calcification. Another patient who had suffered from a maldescensus testicle in his early childhood discharged only one unifocal calcification. Tumor markers including AFP and beta-HCG were normal in 9 patients, but elevated in 1 patient suffering from a testicular tumor (AFP: 73 kU/l; beta-HCG: 10.6 U/l). The hormonal status was normal in 6 patients and pathological 4 patients with the diagnosis of OAT-syndrome.ConclusionTM is a rare condition even in andrological patients. Nevertheless, a thorough scrotal sonography is mandatory in order to rule out testicular malignancy.
