ABSTRACT

BACKGROUND: Help in management of non-palpable testicular tumors. French Urologic Association Genital cancer committee's Edit. OBJECTIVES: To review their characterization at imaging findings of non-palpable testicular tumors. DOCUMENTARY SOURCES Literature review (PubMed, Medline) of urological and radiological studies dealing with testicular tumors using keywords non-palpable/incidental testicular tumors; color Doppler ultrasound; US elastography; magnetic resonance imaging; contrast enhanced sonography; partial surgery. RESULTS: Color Doppler is the basic exam. The size, the presence of microlithts/microlithiasis/macrocalcifications, the vascular architecture are major semiological findings to suggest the benign or the malignant nature of the lesion. Other techniques like multiparametric MRI, contrast-enhanced sonography, sonographic elastography are still in evaluation. The frequency of benign tumors such as Leydig cell tumors lead to preservation management, through improved characterization, monitoring or tumorectomy. LIMITS Non-randomized study - a very few prospective studies. CONCLUSION: The era of total orchiectomy for any uncertain testicular lesion is over. We try the challenge of characterization, and define management's algorithms based on the suspected nature of the tumors.
