ABSTRACT
 Objective: We aimed to investigate sterile pyuria as a risk factor of the postoperative febrile urinary tract infection (UTI) following retrograde intrarenal surgery (RIRS). Material and Methods: The data of 195 patients who underwent RIRS for kidney stones were reviewed retrospectively. The patients were separated into two groups: Those with sterile pyuria were Group 1, and those without pyuria were Group 2. Age, sex, body mass index, concomitant chronic diseases, duration of the operation, ureteral stent placement, stone characteristics, preoperative urine culture, and stone-free status were compared between the two groups. Results: The patients in Group 1 had more concomitant chronic diseases. However, only chronic obstructive pulmonary disease rates were statistically higher in Group 1 (8.26% vs. 0%) (p=0.014). Hydronephrosis was statistically significantly higher in Group 1 than in Group 2 (p=0.008). However, there was no statistically significant difference between the groups in terms of stone characteristics such as stone size (mm), volume (mm3 ), density, and location (p=0.495, p=0.281, p=0.871, and p=0.081, respectively). Furthermore, the overall number of complications was higher in Group 1; however, this difference was not statistically significant between both groups (p=0.706). Conclusion: Our results suggest that pyuria was not associated with postoperative UTI in RIRS operations with a sterile preoperative urine culture.

ÖZET
 Amaç: Bu çalışmamızda, retrograd intrarenal cerrahi (RIRC) sonrası postoperatif ateşli idrar yolu enfeksiyonu (İYE) için bir risk faktörü olarak steril piyüriyi araştırmayı amaçladık. Gereç ve Yöntemler: Böbrek taşı nedeniyle RIRC uygulanan 195 hastanın verileri retrospektif olarak incelendi. Hastalar steril piyüri olanlar Grup 1, piyüri olmayanlar Grup 2 olmak üzere 2 gruba ayrıldı. Yaş, cinsiyet, beden kitle indeksi, eşlik eden kronik hastalıkları, ameliyat süresi, üreter stent hikâyesi, taş özellikleri, ameliyat öncesi idrar kültürleri ve taşsızlık durumu 2 grup arasında karşılaştırıldı. Bulgular: Grup 1'deki hastalarda eşlik eden kronik hastalık sayısı Grup 2'ye göre daha fazla idi. Ancak sadece kronik obstrüktif akciğer hastalığı oranları Grup 1'de istatistiksel olarak daha yüksekti (%8,26'ya karşı %0) (p=0,014). Hidronefroz Grup 1'de Grup 2'ye göre istatistiksel olarak anlamlı derecede yüksekti (p=0,008). Ancak taş boyutu (mm), hacmi (mm3 ), yoğunluğu ve yeri gibi taş özellikleri açısından gruplar arasında istatistiksel olarak anlamlı fark yoktu (sırasıyla p=0,495, p=0,281, p=0,871 ve p=0,081). Ek olarak, toplam komplikasyon sayısı Grup 1'de daha yüksekti; ancak bu fark her 2 grup arasında istatistiksel olarak anlamlı değildi (p=0,706). Sonuç: Sonuçlarımız, steril preoperatif idrar kültürü olan hastalarda piyürinin postoperatif İYE ile ilişkili olmadığını göstermektedir.
