The contemporary rate of non-diagnostic renal biopsy ranges from 15-18%, though may be as high as 42% in challenging cases. Simulated Raman Histology (SRH) is a novel microscopic technique which has created the possibility for rapid, label-free, and high-resolution images of unprocessed tissue which may be viewed on standard radiology viewing platforms. The application of SRH to renal biopsy may provide the benefits of pathologic hematoxylin and eosin (H&E) evaluation during the procedure, thereby reducing non-diagnostic results. METHODS: An 18-gauge core needle biopsy was taken of renal masses from a radical or partial nephrectomy specimens. Histologic images of the fresh, unstained biopsy samples were obtained using a Stimulated Raman Spectroscopy microscope using two Raman shifts: 2845cm-1 and 2930cm-1. These Stimulated Raman Spectroscopic images were then processed to create SRH, which is reminiscent of H&E, and viewed by a genitourinary pathologist. RESULTS: The SRH microscope took 7 minutes to produce a high-quality image of the renal biopsies, figure 1 and 2. The images were interpreted by a genitourinary pathologist and areas of tumor were easily identified as lesional. Figure 1a shows SRH of medullary renal carcinoma, while figure 1b shows representative biopsy SRH for clear cell renal cell carcinoma. CONCLUSIONS: SRH produces high quality images that can be rapidly produced and easily interpreted to determine renal mass biopsy adequacy. Procedural application has promise to decrease the rate of renal mass non-diagnostic biopsies.
