简要总结
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.
详细描述
All patients with a diagnosis of ureteral stone ≤4 mm at the Emergency Department in Helsingborg will be asked to participate. If they give consent data regarding age, gender, stone size, stone location, hydronephrosis, S-creatinine, treatments and results from the follow up CT is extraced from the medical records.

结局指标
主要结局
Number of ureteral stones ≤ 4mm that pass spontaneously
时间窗: From enrolement to passage of the stone or maximum 8 weeks.
Number of participants with residual pain
时间窗: 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.
次要结局
- Proportion of ureteral stone that have passed according to anatomical localisation, S-creatinine and presence of hydronephrosis.(From enrolement to passage of the stone or maximum 8 weeks.)
- QoL form including sick leave and return to full ADL(From enrolement to passage of the stone or maximum 8 weeks.)
