Rectal examination

Rectal examination

Rectal examination can detect nodules within the prostate and advanced disease. Irregular induration, characteristically stony hard in part or in the whole of the gland (with obliteration of the median sulcus), suggests carcinoma. Extension beyond the capsule up into the bladder base and vesicles ( Figure 84.16 ) is diagnostic, as is local extension through the capsule ( Figure 84.17 ).
