Study population: Patients at the emergency department in Helsingborg

Brief 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.

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.

Eligibility criteria: Inclusion Criteria:

* Patient at the emergency department with suspected acute renal colic and an emergency CT within 24 hours 10 May 2023 to 9 May 2024.
