Abstract

Objective: The aim of this study was to compare demographic data in adult patients undergoing percutaneous nephrolithotomy (PNL) for kidney stone disease in university hospitals from Southeastern Anatolia and the Black Sea regions.

 

Material and methods: The demographic data of 535 (53.3%) patients undergoing PNL from Gaziantep University, Department of Urology (GAUN group), and 468 (46.6%) patients undergoing PNL from Ondokuz Mayıs University, Department of Urology (OMU group) were evaluated retrospectively. Patients’ gender, mean age, stone laterality, and size and results of the stone analyses were compared.

 

Results: The mean patient ages were 40.94±13.33 (17-81) and 48.03±13.95 (17-81) years in the GAUN and OMU Groups, respectively, (p=0.0001). The mean stone size was 716.01±449.60 (100-3000) mm2 and 612.7±445.87 (65-3220) mm2 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 oxalate (90.19%), cystine (7.84%), uric acid (5.88%), and struvite (1.96%). In the OMU group, the stone composition 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.
