Renal Complex Cystic Masses: Usefulness of Contrast-Enhanced Ultrasound (CEUS) in Their Assessment and Its Agreement with Computed Tomography

Abstract

CEUS is a very useful tool for assessing RCCM, with good results in terms of consistency and validity. It has a good diagnostic power, with a sensitivity of 100 % and a negative predictive value of 100 %. Its main limitations are the experience required, a special software, and being observer-dependent.

Comparison of the Diagnostic Performance of Contrast-enhanced Ultrasound with That of Contrast-enhanced Computed Tomography and Contrast-enhanced Magnetic Resonance Imaging in the Evaluation of Renal Masses: A Systematic Review and Meta-analysis

“…Six of the 16 included studies were cohort studies [17][18][19][20][21][22] and 10 were descriptive studies [23][24][25][26][27][28][29][30][31][32]; none were RCTs ( Table 1).…”

“…Zhou et al [34] performed this analysis only for CEUS versus CEMR, Zhang et al [33] performed it only for CEUS, and Lan et al [35] performed no separate analysis. The currently available evidence suggests that both CECT and CEMR are considered to be the gold standard in the characterisation of solid RMs and CRMs [1,25,36,37]. However, regarding the available literature, this remains a matter of debate.…”

“…To increase the meaningfulness of CEUS in the assessment of RMs, further clinical trials, namely, appropriately designed multicentre RCTs, are needed. Among the studies we compared with FD by pathology report, four [24,25,28,29] had low specificity for CEUS and CECT ( Table 2), probably due to their small study populations. Further trials should therefore involve larger patient samples in order to achieve higher specificity.…”

Differential diagnosis of complex renal cysts

“…К істозна форма нирково клітинного раку становить 5-7% [1], а за останніми даними -навіть 10% випадків усіх пухлин нирок [2]. Враховуючи загальну поширеність рідин них захворювань нирок, >70% становлять безсимптомні ниркові новоутворення [3], що вимагає чітко розділити цю патологію.…”
