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)

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).

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.

Examples

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

# Example 2: High Risk
# 70yo Male, No Hx Hydro, No CHF
# Score = 1 + 1 + 0 + 0 = 2
licurse_renal_ultrasound_score(1, 1, 0, 0)
