Patients included in the study after successful treatment of the acute attack were randomized upon discharge from the Emergency Department into three groups: oral paracetamol-tramadol group, oral paracetamol-caffeine group and oral placebo group.

Read the detailed description

This is a prospective, randomized, single-blind study. Patients included in the study after successful treatment of the acute attack were randomized upon discharge from the Emergency Department into three groups: oral paracetamol-tramadol group, oral paracetamol-caffeine group and oral placebo group.

Different parameters are collected on a standard form prepared for all cases of renal colic included in our study. This sheet essentially contains:

Temperature, systolic and diastolic blood pressure, heart rate, pain intensity assessed by VAS, abdominal tenderness as well as the existence of Giardano signs.

Additional examinations were not systematically carried out for all patients: AUSP, ECBU, renal ultrasound, creatinemia and blood sugar. Their realization depended on the clinical context.

The use of imaging was done following the indications specified in the text of the consensus of the French Society of Emergency Medicine (updated in 2008)

Inclusion criteria

  • -Age > 18 years old.
  • Consent to participate in the study.
  • Pain in the flank/lumbar fossa of sudden onset with urine strips and/or imaging corresponding to the diagnosis of renal colic.
  • Pain score at discharge \< 30 (visual analog scale - VAS or verbal numerical scale - VAS from 0 to 100).

Exclusion criteria

Exclusion Criteria:

  • -Inability to appreciate pain according to the VAS.
  • Pregnant or breastfeeding woman.
  • Renal insufficiency with \< 60 ml/min.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 19, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
