Association between chronic pancreatitis and urolithiasis: A population-based cohort study

Area of Science:

• Gastroenterology and Urology
• Epidemiology
• Public Health

Background:

• Chronic pancreatitis (CP) can lead to malabsorption, potentially increasing urolithiasis risk.
• Previous research suggests a link between malabsorption and elevated intestinal oxalate absorption, a factor in stone formation.
• However, a direct association between CP and urolithiasis has not been established.

Purpose of the Study:

• To investigate the association between chronic pancreatitis and the incidence of urolithiasis.
• To quantify the risk of developing urolithiasis in patients with CP compared to those without.
• To explore how comorbidities influence the relationship between CP and urolithiasis.

Main Methods:

• A population-based cohort study utilizing the National Health Insurance Research Database.
• Identified 15,848 patients diagnosed with CP between 2000-2010, propensity-matched with a control group.
• Followed patients until 2011 to determine the incidence of urolithiasis, considering various demographic and clinical factors.

Main Results:

• Patients with CP exhibited a significantly higher cumulative incidence of urolithiasis (1.89-fold increased risk).
• The association between CP and urolithiasis was observed across all age and sex groups.
• The relative risk of urolithiasis attributable to CP was notably higher in patients without comorbidities.

Conclusions:

• Chronic pancreatitis is independently associated with an increased risk of urolithiasis.
• The study underscores the importance of considering urolithiasis in CP patients, particularly those without other comorbidities.
• Recommendations include implementing urolithiasis surveillance and patient education programs for individuals with CP.
