Urolithiasis in general practice. An epidemiological study from a Norwegian district

Area of Science:

• Urology
• Epidemiology
• Public Health

Background:

• Urolithiasis, commonly known as kidney stones, presents a significant health concern.
• Understanding the epidemiological patterns of kidney stone incidence is crucial for public health initiatives.

Purpose of the Study:

• To investigate the incidence and seasonal variation of urolithiasis in a general practice setting in Eastern Norway.
• To compare the characteristics of unselected urolithiasis patients with those suffering from recurrent stone disease.

Main Methods:

• Retrospective analysis of urolithiasis cases presenting with stone colic in general practice over four years.
• Comparison of incidence data with a selected cohort of patients with recurrent urolithiasis.

Main Results:

• An incidence rate of two cases per 1000 inhabitants per year was observed.
• A distinct seasonal variation was noted, with peak incidence during winter and autumn months.
• Male patients (2.7:1 ratio) and individuals with sedentary occupations showed a higher prevalence.
• Peak incidence occurred in middle-aged groups (30-60 years).
• Unselected patients had significantly fewer stone episodes and shorter disease duration compared to recurrent cases.

Conclusions:

• Urolithiasis incidence exhibits seasonal fluctuations, particularly in winter and autumn.
• General practice data provides insights into the broader population incidence, distinct from specialized recurrent stone disease cohorts.
• Risk factors such as male gender, sedentary lifestyle, and middle age are confirmed.
