    Purpose: We assessed factors affecting complication rates of percutaneous nephrolithotomy in children. Materials and Methods: We retrospectively evaluated data on 1,205 renal units in 1,157 children treated with percutaneous nephrolithotomy at 16 Turkish centers between 1991 and 2012. Of the patients 28.3% had a history of urolithiasis. Complications were evaluated according to the Satava classification system and modified Clavien grading system. Univariate and multivariate analyses were done to determine predictive factors affecting complication rates. Results: A total of 515 females and 642 males were studied. Mean +/- SD patient age was 8.8 +/- 4.7 years (range 4 months to 17 years). Mean +/- SD stone size, operative time and postoperative hospital stay were 4.09 +/- 4.06 cm 2, 93.5 +/- 48.6 minutes and 5.1 +/- 3.3 days, respectively. Postoperative stone-free rate was 81.6%. A total of 359 complications occurred in 334 renal units (27.7%). Complications were intraoperative in 118 cases and postoperative in 241. While univariate analysis revealed that stone history, positive urine culture, operative time, length of hospitalization, treatment success, punctured calyx and location of the stone significantly affected the complication rates (p <0.05), operative time, sheath size, mid calyceal puncture and partial staghorn formation were the statistically significant parameters affecting complication rates on multivariate logistic regression analysis. Conclusions: Percutaneous nephrolithotomy is the treatment of choice for most renal calculi in children. The technique is effective and safe in children, with a high success rate and a low rate of major complications. The significant factors identified should be considered by clinicians to decrease associated complication rates.

    THE MIGRATIONS FROM CAUCASIA TO MUS REGION AND IMMIGRANTS SETTLEMENT (1865-1905)
    (Selcuk Univ, Inst Turkish Studies, 2018) Ozturk, Ahmet; Toprak, Serap
    Russia, which had been defeated by the Crimean War, began to carry out policies of oppression, violence and assimilation against the people of the region on the grounds that the people of the Caucasus did not give them the necessary support. As a result of these policies implemented by Russia, the people of the region have to migrate to the territories of the Ottoman State which have historical, religious and economic ties. The immigration movement that began with the voluntary arrival of some Caucasian families in the first half of the 1850s on the territory of the Ottoman State began to gain intensity from 1859. But the migrations which have been declining slightly began to intensify again after the Ottoman-Russian War of 1877-1878. However, after the Ottaman-Russian War of 1877-1878, the migration movement also increased again. This immigration movement, which increased and decreased during various periods, continued until the first years of the 20th century. From the end of the 1850s thousands of immigrants arrived from the Caucasus to the Mus region, which opened at the settlement. In this study, population characteristics of the Caucasian immigrants wpreferred Mus region as the settlement area, the settlement places and socio-economic relations between local inhabitants and immigrants were examined.
