Neutrophil to lymphocyte ratio as an early indicator for ureteral catheterization in patients with renal colic due to upper urinary tract lithiasis.

ABSTRACT:

Purpose

To evaluate whether the neutrophil-to-lymphocyte ratio (NLR) can predict the need for ureteral catheterization in patients with renal colic.

Materials and methods

We retrospectively studied 15,887 patients with renal colic between 2005 and 2019. Patients with prior antibiotics treatment (156), with hematological diseases (15), with negative computerized tomography scan (CTS) for stone disease (473) or with no available laboratory findings (1750) were excluded. A ureteral double J stent (DJS) was inserted in case of ongoing pain, fever, sepsis, single kidney and elevated blood creatinine levels concomitant with hydronephrosis. A cut-off value of 2.1 NLR was determined to stratify and to compare patients using multivariable logistic regression models. A locally weighte
