“…However, none of these modalities can reliably differentiate between benign and malignant solid renal masses [5][6][7]. Ultrasound elastography has shown some potential utility in distinguishing focal angiomyolipomas from RCC in early studies [8]. However the results of these studies are controversial, and more research is necessary before the modality can achieve wide acceptance.…”

“…The non-diagnostic rate is higher when the renal mass is 2 cm or less in diameter, a cystic tumour, an upper tumour, or biopsied using 3 or fewer cores ( Fig. 5 ) [ 15 ]. Accordingly, the diagnostic rate for US-guided small (<4 cm) renal mass biopsies is 81% [ 15 ], while that for US-guided large (≥4 cm) renal mass biopsies ranges from 82% to 92% [ 16 , 17 ].…”

Thus, US-guided biopsy can easily be used to sample large renal tumours; however, in larger renal masses, the likelihood of central necrosis is higher.…”

“…CT-guided renal mass biopsy yields a higher diagnostic rate than US-guided renal mass biopsy. The diagnostic rate of CT-guided renal mass biopsy has been reported to range from 94% to 98% [ 18 - 20 ], while that of US-guided renal mass biopsy has been found to range from 81% to 92% [ 15 - 17 ]. When a renal mass is visible on US, US-guided biopsy is recommended.…”

Ultrasound (US) is often used to guide various interventional procedures in the genitourinary (GU) tract because it can provide real-time imaging without any radiation hazard. Moreover, US can clearly visualize the pathway of an aspiration or biopsy needle to ensure the safety of the intervention. US guidance also helps clinicians to access lesions via the transabdominal, transhepatic, transvaginal, transrectal, and transperineal routes. Hence, US-guided procedures are useful for radiologists who wish to perform GU interventions. However, US-guided procedures and interventions are difficult for beginners because they involve a steep initial learning curve. The purpose of this review is to describe the basic principles and techniques of US-guided GU interventions.

Objective: Fine-needle aspiration cytology (FNAC) based on a liquid-based preparation is a safe and valuable diagnostic tool. However, due to unfamiliarity with this method and the considerably altered morphology that is associated with it, diagnosing renal cell carcinoma (RCC) from this type of preparation remains a challenge for cytopathologists. The aim of this study was to evaluate the cytomorphological characteristics of SurePath™ (SP)-based preparations compared with conventional smear (CS), and also the role of SP-based FNAC in the diagnosis of clear-cell RCC (CRCC), the most common primary renal malignancy. Study Design: Ex vivo FNAC of both tumors and normal renal parenchyma was prepared from 73 cases. Comparative cytomorphological analysis between liquid-based cytology (LBC) and CS as well as Fuhrman nuclear grading (FNG) was carried out. Immunocytochemistry was performed from normal and CRCC cytology specimens. Results: Normal renal cytology (NRC) showed no significant morphological differences between LBC and CS. For CRCC, LBC showed small, fragmented cell clusters, a 3-dimensional configuration, distinct cytoplasmic vacuoles, and irregular nuclear contours when compared with CS. FNG was overgraded with LBC compared to with CS. AMACR was the most valuable immunocytochemical marker for distinguishing CRCC from NRC. Conclusion: Once cytopathologists become familiar with the altered cytomorphological features of CRCC, FNAC, along with immunocytochemistry, may prove helpful for diagnosis.
