Introduction: Ureterolithiasis is one of the main causes of acute abdominal pain in emergency care. In most cases, treatment is conservative, with the body itself expelling the stone when urinating. However, in rare cases, spontaneous retrograde migration of the ureteral calculus to the renal pelvicalyceal system may occur, resulting in relief or resolution of symptoms, but the risk of new obstructive events remains. Case report: A male patient was diagnosed with distal ureterolithiasis near the ureterovesical junction, which was managed conservatively. After becoming oligosymptomatic within two days, another computed tomography scan was performed, which identified the stone's spontaneous migration to the renal calyx. Conclusion: This case demonstrates the importance of diagnosing ureterolithiasis and its follow-up, which can be more complex than usual, highlighting the relevance of performing CT in this context, especially to plan the best therapeutic intervention, or even to avoid unnecessary procedures.
