Comparison of demographic data in patients undergoing percutaneous nephrolithotomy in Southeastern Anatolia and the Black Sea region: A multicenter study Güneydoğu Anadolu ve Karadeniz Bölgesi'nde, perkütan nefrolitotomi uygulanan hastalara ait demografik verilerin karşilaştirilmasi: Çok merkezli çalişma

Objective: The aim of this study was to compare demographic data in adult patients undergoing percutane- ous nephrolithotomy (PNL) for kidney stone disease in university hospitals from Southeastern Anatolia and the Black Sea regions. in the GAUN and OMU Groups, respectively (p=0.0001). There were no statistically significant differences between the groups with respect to stone laterality (p=0.196), and gender of the patients (p=0.65). Stone analysis revealed that the distribution of stone composition was as follows in the GAUN group: Ca oxa- late (90.19%), cystine (7.84%), uric acid (5.88%), and struvite (1.96%). In the OMU group, the stone composi- tion was as follows: Ca oxalate (86.84%), cystine (1.34%), uric acid (13.15%), and struvite (9.21%). Conclusion: The incidence of kidney stone disease varies throughout Turkey based on etiological factors, and a higher incidence of kidney stone disease is observed in the Southeastern Anatolia region endemically. Lower mean ages and higher stone sizes in patients undergoing PNL in southeastern Anatolia suggest that geographic factors can affect stone disease.
