licurse_renal_ultrasound_score: Licurse Score for Renal Ultrasound in AKI

Description

Calculates the Licurse Score to stratify the utility of renal ultrasonography (RUS) in patients presenting with Acute Kidney Injury (AKI). The score identifies patients at low risk for hydronephrosis (post-renal obstruction), potentially reducing unnecessary imaging.

Usage

licurse_renal_ultrasound_score(age_ge_65, male_sex, history_hydronephrosis,
                               history_chf)

Value

A list containing:

Licurse_Score

The calculated score (Range -1 to 3).

Risk_Category

Classification of risk (Low, Intermediate, High, Very High).

Prob_Hydronephrosis

Estimated probability of detecting hydronephrosis on ultrasound.

Recommendation

Guidance on the necessity of imaging.

Arguments

age_ge_65

Numeric (0 or 1). Is the patient 65 years of age or older? (1 = Yes, +1 point).

male_sex

Numeric (0 or 1). Is the patient male? (1 = Yes, +1 point).

history_hydronephrosis

Numeric (0 or 1). Does the patient have a known history of hydronephrosis? (1 = Yes, +1 point).

history_chf

Numeric (0 or 1). Does the patient have a history of Congestive Heart Failure? (1 = Yes, -1 point).

Examples

# Example 1: Low Risk (No imaging needed)
# 40yo Female, No Hx Hydro, Hx CHF
# Score = 0 + 0 + 0 - 1 = -1

# Example 2: High Risk
# 70yo Male, No Hx Hydro, No CHF
