Wedge resections are performed for the removal of relatively small, localized lesions or for the determination of organ suitability as donor kidney. The latter are generally very small (less than 1.0 cm).
Measure the specimen. If large, weigh it as well. Describe the cortical surface. If a mass lesion is clinically suspected, examine the resection margins for tumor before inking.
Cut the specimen perpendicular to the margins. Measure and describe (shape, color, consistency) of any lesion(s) which you see. Measure the distance between the edge of the lesion and the nearest resection margin. If the specimen is oriented, note which margin this is. Describe the uninvolved renal parenchyma.
Received in formalin, labeled _____ and “_____”, is a __ x __ x __ cm, __ g wedge resection of kidney. No orientation is provided. There is no attached capsule. The exposed cortical surface is smooth/pitted and has a __ cm raised/flat, _____ (color) area. The resection margins are irregular and _____ (color), but without a mass, and are inked _____ (ink color). There is a __ x __ x __ cm _____ (color, shape, consistency) nodule within the parenchyma, located __ cm from the nearest _____ (location) resection margin. The uninvolved parenchyma is _____ (color) and without additional lesions.
#__ - #__ = nodule and nearest margins; __ pieces in each.
#__ = uninvolved parenchyma including cortical surface; __ pieces.
