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

Overview

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.

Detailed description

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.

Primary outcome measures

  • Number of ureteral stones ≤ 4mm that pass spontaneously [Time frame: From enrolement to passage of the stone or maximum 8 weeks.]
  • Number of participants with residual pain [Time frame: From enrolement to passage of the stone or maximum 8 weeks.]
Secondary outcome measures (2)
  • QoL form including sick leave and return to full ADL [Time frame: From enrolement to passage of the stone or maximum 8 weeks.]
  • Proportion of ureteral stone that have passed according to anatomical localisation, S-creatinine and presence of hydronephrosis. [Time frame: From enrolement to passage of the stone or maximum 8 weeks.]

Eligibility criteria

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

  • Those who decline to participate, those who are put under guardianship or is less than 18 years old.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
