Follow-Up of Ureteral Stones ≤4 mm

Follow-Up of Ureteral Stones ≤4 mm: Evaluate the Proportion of Spontaneous Passage and Assess if Symptoms and Stone Characteristics Can Predict Stone Passage

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.

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.

Inclusion Criteria:

• all patients with acute renal colic where a CT within 24 hours shows an ureteral stone ≤ 4mm and there is no need for acute intervention.

Exclusion Criteria:
