Clinical Trial Summary

Acute obstructive pyelonephritis is a condition with a high risk of complications and may require admission to the intensive care unit.

Most of the available data on this condition comes from small, retrospective, single-centre series.

To date, no large-scale study has examined the factors associated with the prognosis of patients admitted to intensive care for acute obstructive pyelonephritis.

The aim of this study is to describe the population and prognosis of patients admitted to the intensive care unit for the management of acute obstructive pyelonephritis, and to identify factors associated with a poor prognosis in these patients.

Description:

The retrospective and multicenter study consists of a retrospective and pseudonymous collection of data from medical reports of patients treated, over the period 2015-2022, in each intensive care unit agreeing to participate, .

Investigators from each participating center will be responsible for screening on all hospitalized patients over the period 2015-2022. Patients who have been hospitalized for the management of acute obstructive pyelonephritis will be included, in the absence of non-inclusion criteria.
