Urolithiasis and cystic fibrosis

J Urol. 1996 May;155(5):1563-4.


Purpose: We determined whether cystic fibrosis patients are at increased risk for the development of urolithiasis.

Materials and methods: Telephone interviews were conducted with 201 cystic fibrosis patients older than 15 years to identify those with a history of urolithiasis. Histories were confirmed by chart review, and only patients with urolithiasis documented by excretory urography, renal ultrasound or spontaneous passage of a stone were included.

Results: A total of 11 patients (5.5%) had documented urolithiasis, with 2 or more episodes in 7. Mean age at initial episode was 27.0 years (range 19 to 33).

Conclusions: Cystic fibrosis patients may be at increased risk for urolithiasis compared to age-specific prevalence rates for stone disease in the general population.
