Stone composition of urinary tract stones from our region

Abstract

Objective: To evaluate the spectrum of urinary tract stone compositions in patients managed at one center.
Methods: A total of 710 urinary calculi, passed spontaneously or after extracorporeal shock-wave lithotripsy as well as collected by endoscopic or open surgical procedures were analyzed by applying chemical and physicochemical methods primarily used for detecting minerals in our laboratory. Results: The distribution of stone compositions were noted as 454 (64.9%) calcium oxalate; 104 (14.6%) calcium phosphate; 99 (13.9%) struvite; 24 (3.3%) uric acid; 21 (2.9%) mixed; 5 (0.7%) cystine; and 3 (0.4%) xantine stones. Conclusion: Calcium stones, calcium oxalate in particular predominate among other types of urinary calculi in our center. Infection stones still have a considerable incidence that stays near to calcium phosphate calculi. This data can be helpful for dietary recommendations and treatment plans in cases without stone type assessment.

Bölgemizdeki üriner sistem taþlarýnýn taþ içeriði

Abstract

Amaç: Bölgemizde tedavi edilen üriner sistem taþ hastalarýnýn taþ kompozisyonunun spektrumunu deðerlendirmek. Metod: Ekstrakorporeal þok dalga litotripsi, endoskopik veya çeþitli açýk cerrahi yöntemleriyle elde edilenler ile hastalarýn kendi düþürdükleri toplam 710 üriner taþ, laboratuarda esas olarak mineralleri saptamak için kullanýlan kimyasal ve fizikokimyasal yöntemler kullanýlarak incelendi.
Bulgular: Taþlarýn 454ü (%64.9) kalsiyum okzalat, 104ü kalsiyum fosfat (%14.6), 99u struvite (%13.9), 24ü ürik asit (%3.3), 21i karýþýk (%2.9), 5i (%0.7) sistin, 3ü ksantin (%0.4) idi. Sonuç: Bizim bölgemizde kalsiyum taþlarý, özellikle kalsiyum okzalat diðer taþ tipleri arasýnda daha fazla görülmektedir. Enfeksiyon taþlarý da kalsiyum fosfat taþlarýna yakýn seviyede belirgin bir insidansa sahiptir. Bu veriler taþ analizi deðerlendirmesi yapýlmamýþ hastalarda beslenme önerileri ve tedavi planlarý için yararlý olabilir.
