The goal of this clinical trial is to evaluate the proportion of ureteral stones ≤4 mm that pass spontaneously within 4 and 8 weeks and assess if pain, blood test (S-creatinine), stone size, stone location and hydronephrosis can predict stone passage. The participants will be asked to fill in a questionare regarding symptoms, give a blood test and undergo a follow-up computed tomography.

Primary outcome measure(s)
Number of ureteral stones ≤ 4mm that pass spontaneously — From enrolement to passage of the stone or maximum 8 weeks.
Number of participants with residual pain — From enrolement to passage of the stone or maximum 8 weeks. Residual pain is measured with VAS (visual analogue scale), values 0-10. VAS 0 = no pain and VAS 10 = worst possible pain.
