Abstract
Bedside renal ultrasound (US) can be utilized to evaluate for nephrolithiasis, renal failure, urinary retention or decreased output, and hematuria (Figs. 28.1, 28.2, 28.3, 28.4, 28.5, 28.6, 28.7, 28.8, 28.9, 28.10, 28.11, and 28.12, Videos 28.1, 28.2, 28.3, 28.4, and 28.5). Although CT scan has classically been used to diagnose kidney stones, US has gained favor owing to its rapid application at the bedside, cheaper cost, and avoidance of ionizing radiation [1]. Larger kidney stones are more likely to be seen on US [2, 3], but more frequently it is the visualization of hydronephrosis as a secondary sign that can help point toward the diagnosis and guide management [4, 5].
