“…The presence of this diagnostic sonographic sign could allow more conservative management (observation and follow-up) than patients with renal colic without the SK sign. 17 In summary, the SK sign is a frequently associated with acute renal colic, and based on the observations provided, it was easy to recognize. The presence of the SK sign could be combined with other diagnostic sonographic criteria, already in use to detect acute renal colic.…”

Objective: During acute renal colic due to nephrolithiasis, a new sonographic diagnostic sign was noted, called “a swinging kidney.” This term was given due to a characteristic anteroposterior “rolling” movement of the kidney. A preliminary investigation was conducted to evaluate the correlation between this new diagnostic sign and nephrolithiasis. Materials and Methods: An exploratory observational investigation was conducted on adult patients who accessed an emergency medicine department, with acute renal colic, between June 1, 2019, and October 31, 2019. Results: Thirty-seven patients were enrolled. The “swinging kidney” was present in 26 cases (70%). This sign was correlated with a stone’s diameter of less than 10 mm (χ2: 4.68; P = .031), and with a stone localization in the juxtavesical ureter tract site (χ2: 10.83; P = .029). Spontaneously stone expulsion was correlated with the presence of the “swinging kidney” (χ2: 4.66; P = .031); with the minor degree of hydronephrosis (χ2: 16.82; P = .0008), and with a distal localization of the stone (χ2: 25.11; P = 1:47 × 10−5). Conclusion: The “swinging kidney” may be a promising diagnostic sign that could be useful in diagnosing nephrolithiasis besides the other indirect sonographic signs. This new diagnostic sign could have a prognostic role.
