urinary tract, urolithiasis, prevention urolithiasis


People suffer from urinary lithiasis for thousands of years (at least from 4800 b.c.). Despite enormous improvement regarding more or less invasive methods of treatment prophylaxis of recurrent urinary stones is still significant issue. Knowledge of particular etiologic factors of urinary lithiasis allows to construct principals of preventive actions.
The aim of the present study is to evaluate the effects of prophylaxis of urinary lithiasis in children.
material and method
480 children with urinary lithiasis were treated in the Department from 1976 to 2002. Of these 480 children, 55 (28 > i 27 +) children with recurrent urinary lithiasis were enrolled. Patients age determined during diagnosis ranged from 10/12 to 16 years. There were 1-8 episodes of recurrent urinary lithiasis before the children were admitted to our Clinic. Invasive procedures were most frequently performed. Independent stones elimination occurred in few cases.
Examinations of blood and urine allowed to establish the etiology of urinary lithiasis in all 55 cases.
In 38 (69,1%) children metabolic disturbances were determined: 24 - idiopathic hypercalciuria, 5 - urinary stones composed of uric acid, 8 - cystynuria, and in 1 - incomplete form of distal tubular renal acidosis. In other patients: infectious urinary lithiasis - 7, idiopathic oxalic lithiasis - 9, tubular sponge kidney - 1 were diagnosed. Prophylaxis was carried out knowing the etiology and the type of urinary lithiasis.
Until 1999 recurrences were observed in 4 children with cystic stones and in 1 child with incomplete form of distal renal acidosis who spontaneously eliminated the stones. Since 2000 in 8 children with cystic urinary lithiasis Captopril, Potacitrin and regular fluid oversupply were applied. There has been no recurrence since then.
