Study summary

The goal of this observational study is to learn more about diagnostics in patients with suspected acute renal colic at the emergency department. The main questions it aims to answer are:

  • How many patients with symtoms of urolithiasis have a stone in the urinary tract at the emergency computed tomography (CT)
  • Location and size of the stones.
  • Evaluate time to intervention and closure and if this has changed due to emergency CT.

Participants are patients with symtoms of suspected acute renal colic at the emergency department in Helsingborg with an emergency CT within 24 hours.

Read the detailed description

Since October 2022 The National Guidelines in Sweden recommend emergency CT for patients with suspected acute renal colic at the emergency department. In May 2023 the Department of Urology implemented this new regime with emergency CT for these patients in collaboration with the Department of Emergency and the Department of Radiology. This study aims to evaluate the first year (May 2023 to May 2024) with this new regime. Data regarding these patients where gathered regarding decriptive data, data regarding the stone, interventions and follow up. The investigators aim to compare the data with data from a soon to be published (Scandinavian Journal of Urology) article evaluating the situation regarding these patients during one year 2018-2019.

What researchers measure

Primary outcomes

  1. Numbers of patients with a kidney stone on emergency CT

    Number of patients with a kidney stone on emergency CT. Size and location of the stone as well as time to intervention and closure for those with a stone.

    Time frame: From enrollment until the date participants are considered stone free, up to 6 months regarding participants with stone. For participants without a stone, the time frame extends over the duration of their hospitalization, up to 30 days.

Secondary outcomes

  1. Numbers of visits to the emergency department

    Has the number of visits to the emergency department due to acute renal colic changed before and after implementation of emergencty CT

    Time frame: Time from enrollment until the date the participants are considered stone free, up to 6 months.
