It is known that recurrent nephroliths form in about half of the operated patients within 5 years after operation while 60% of all recurrences occur 3 years after removal of the primary concrement. To prevent recurrent nephroliths, it is important not only to detect metabolic disturbances but also to investigate chemical composition of uroliths. Mineral composition of 112 stag-horn concrements from patients living in the south of Russia was studied with x-ray phase analysis which showed that 62.9% concrements had mixed composition. Compared to patients with primary stag-horn nephrolithiasis, patients with recurrent one more often had calcium-phosphate and calcium-oxalate concrements than urate concrements. Chemical composition of the concrements depended on features of the relief of the region where the patients live. Newly established mineral characteristics of stag-horn concrements in the citizens of south Russia should be taken into consideration both in surgical treatment and follow-up of such patients.
