Summary
Tunisian adults show a higher incidence of kidney stones (renal lithiasis) in men compared to women, with most stones located in the upper urinary tract. Surgery remains the primary treatment method for large calculi.
Area of Science:
- Urology
- Nephrology
- Epidemiology
Context:
- Analysis of 574 urinary lithiasis cases in Tunisian adults.
- Comparison of epidemiological profiles with under-developed countries.
- Observed differences in stone characteristics and treatment compared to existing literature.
Purpose:
- To define the epidemiological profile of urinary lithiasis in Tunisian adults.
- To investigate the frequency, location, age distribution, and treatment of kidney stones.
- To compare findings with international literature and understand regional variations.
Summary:
- A higher prevalence of renal lithiasis was observed in men (male-to-female ratio 2.4), with an average age of onset around 40 years.
- Upper urinary tract calculi were found in 94% of cases.
- Surgical intervention (51%) was the most frequent elimination method, attributed to large stone size and recent introduction of lithotripsy.
Impact:
- Highlights unique epidemiological characteristics of urinary lithiasis in Tunisia.
- Suggests potential regional factors influencing stone formation and presentation.
- Informs clinical practice regarding stone management strategies in the region.
