[Comparative study of the diagnostic preciseness of scrotoscope and B-ultrasonography on scrotal lesions].

Thirty patients with scrotal lesions were examined with both scrotoscope and B-ultrasonography. In comparison with the outcome of pathological results, the total diagnostic effectiveness rate of the scrotoscope (73.3%) was significantly higher than that of B-ultrasonography (46.7%). Scrotoscope (86.7%) was far more precise than B-ultrasonography (60%) in distinguishing a benign lump from a tumour (P < 0.05). However, when applied to separate a cyst from a solid lump, and epididymitis from epididymal tuberculosis, the two methods did not reveal remarkable difference (P > 0.05). Scrotoscope allows biopsy and removal of the lump under direct vision. It is handy and safe and is desirable to use on a larger clinical scale.
