Abstract

PIZZAROSSA, Ana Carina  and  RODRIGUEZ, Marina. Renal infarction: systematic review of symptoms of clinical suspicion and repercussion on renal function. Rev. Urug. Med. Int. [online]. 2019, vol.4, n.2, pp.4-14. ISSN 2393-6797.  http://dx.doi.org/10.26445/04.02.3.

Introduction:

Renal infarction is a rare entity and is under-diagnosed, so a high index of clinical suspicion is needed for its diagnosis.

Objective:

To determine the most frequent clinical and paraclinical characteristics in renal infarction, highlighting the impact on renal function.

Methodology:

A systematic review of a series of cases was carried out in PUBMED and SciELO with the terms: "renal infarction" and "renal infarct". Variables were studied: demographic, clinical and paraclinical. In the case of paraclinical variables, the percentage of patients with high values ​​of each of them was analyzed. The statistical analysis was performed with EPI INFO 7. 2.

Results:

The most frequent symptoms and signs were oliguria, flank and abdominal pain, nausea, fever and vomiting. Paraclinical parameters altered were: LDH, CRP and white blood cells. Acute renal injury was found in 30.8% of patients, progression to chronic kidney disease was observed in 17.3% and progression to end-stage renal disease was observed in 5.2% of patients.

Discussion and conclusions:

The determination of the most frequent clinical and paraclinical characteristics of renal infarction can be used to reduce the diagnostic delay, which has therapeutic consequences.

Keywords : Renal infarction; flank pain; LDH; renal injury.
