Effects of dietary interventions on 24-hour urine parameters in patients with idiopathic recurrent calcium oxalate stones

AbstractThe aim of this study is to investigate the effects of dietary factors on 24-hour urine parameters in patients with idiopathic recurrent calcium oxalate stones. A total of 108 of idiopathic recurrent calcium oxalate stones were included in the study. A 24-hour urinalysis was performed and metabolic abnormalities were measured for all of the patients. All of the patients were given specialized diets for their 24-hour urine abnormalities. At the end of first month, the same parameters were examined in another 24-hour urinalysis. Hyperoxaluria, hypernatruria, and hypercalciuria were found in 84 (77%), 43 (39.8%), and 38 (35.5%) of the patients, respectively. The differences between the oxalate, sodium, volume, uric acid, and citrate parameters before and after the dietary intervention were significant (p < 0.05). The calcium parameters were not significantly different before and after the intervention. We found that oxalate, sodium, volume, uric acid, and citrate—but not calcium—abnormalities in patients with recurrent calcium oxalate stones can be corrected by diet. The metabolic profiles of idiopathic calcium oxalate stone patients should be evaluated and the appropriate dietary interventions should be implemented to decrease stone recurrence

Occurence and treatment of stone street after extracorporeal shock wave lithotripsy

Bobrek tasi nedeniyle ekstrakorporeal sok dalga litotripsi (ESL) uygulanan 4,200 olgu tas yolu olu§ma sikligi, sonuglan ve tedavi yakla§imlan agisindan retrospektif olarak degerlendirildi. Olgulann 256'sinda (% 6) tas yolu gelistigi saptandi. Bunlardan duzenli izlemi olan 217 hasta galismaya dahil edildi. Tas yolu olusma sikligi 1 cm'den kuciik taslarda % 1.3, 3 cm'den buyuk taslarda ise % 20 olarak bulundu. Olgulann 103'unde (% 47.6) spontan, 91'inde (% 41.9) yine ESL ile duzelme saglandiT ESL'nin ba§ansiz oldugu 16 olguya (% 7.3) ureterorenoskopi, 7 olguya (% 3.2) ise ureterolitotomi yapildi. '"|as yolu geli§en olgular dikkatli izlenmeli ve dilatasyon gelisen olgularda ilk tedavi segenegi tekrar ESL olrrfalidir. ESL'nin basansiz oldugu olgularda ise tercih edilen tedavi yontemi ureterorenoskopi olmakla birlikte, acik cerrahi girisim ender de olsa gerekebilmektedir.Occurence And Treatment Of Stone Street After Extracorporeal Shock Wave Lithotripsy- A total of 4,200 patients xvith kidney stones were evaluated for the occurence, treatment and outcome of stone streets after extracorporeal shock wave lithotripsy (ESL) treatment, retrospectively. Of these patients 256 (6 %) had stone street formation and 217 patients with regular folloiv-ups were included into the study. The incidence of stone street formation ivas 1.3 %for stones smaller than 1 cm, and 20 % for stones larger than 3 cm. Spontaneous relief was attained in 103 patients (47.6 %), ivhile additional ESL was necessary in 91 patients (41.9 %). Sixteen patients (7.3 %) underwent ureterorenoscopy and 7 (3.2 %) cases were treated with ureter oliihotomy after repeat ESL failure. In conclusion, patients with stone street formation should be observed carefully and ESL should be considered again in patients with dilated upper tracts. Ureterorenoscopy is the method of choice if ESL remains unsuccessful, and open surgery may be necessary in rare cases
