Objective: To evaluate the efficacy, safety, and clinical outcomes of retrograde intrarenal surgery in a large patient cohort and identify factors affecting treatment success across different demographic groups. Material and Methods: This retrospective study analyzed 3,781 patients who underwent retrograde intrarenal surgery between January 2013 and December 2023. Patient demographics, stone characteristics, operative parameters, and complications were evaluated. Stone-free rates, operative times, and complications were assessed according to stone location and size. The primary outcome was stone-free status evaluated by non-contrast computed tomography at 3 months postoperatively. Multivariate analysis was performed to identify predictors of treatment success. Results: The overall stonefree rate was 88.7%. Mean stone size was 13.9±5.6 mm, with mean operative time of 52 minutes. Stone distribution was: lower calyx (42.5%), renal pelvis (30.0%), upper calyx (15.2%), and middle calyx (12.3%). Total complication rate was 12.5%, with minor complications (ClavienDindo Grade I-II) occurring in 11.4%, moderate complications (Grade III) in 1.0%, and major complications (Grade IV) in 0.05% of cases. Multivariate analysis identified stone size >15mm (odds ratio [OR]: 0.68, p<0.001), lower calyx location (OR: 0.75, p=0.004), and multiple stones (OR: 0.82, p=0.042) as significant predictors of treatment success. Patient satisfaction averaged 8.4 out of 10, showing strong correlation with stone-free status (correlation coefficient: 0.85, p<0.001). Conclusion: Retrograde intrarenal surgery demonstrates high efficacy and safety in treating upper urinary tract stones, with favorable outcomes across different patient groups. Stone size, location, and multiplicity significantly influence treatment success, while complication rates remain low with standardized technique. These findings can aid in optimizing patient selection and improving preoperative counseling.

Amaç: Geniş hasta kohortunda retrograd intrarenal cerrahinin etkinliğini, güvenliğini ve klinik sonuçlarını değerlendirmek ve farklı demografik gruplarda tedavi başarısını etkileyen faktörleri belirlemek. Gereç ve Yöntemler: Bu retrospektif çalışma, Ocak 2013-Aralık 2023 tarihleri arasında retrograd intrarenal cerrahi uygulanan 3.781 hastayı analiz etti. Hasta demografisi, taş özellikleri, operatif parametreler ve komplikasyonlar değerlendirildi. Taş lokasyonu ve boyutuna göre taşsızlık oranları, operasyon süreleri ve komplikasyonlar değerlendirildi. Birincil sonuç, postoperatif 3. ayda kontrastsız bilgisayarlı tomografi ile değerlendirilen taşsızlık durumuydu. Tedavi başarısının öngördürücülerini belirlemek için çok değişkenli analiz yapıldı. Bulgular: Genel taşsızlık oranı %88,7 idi. Ortalama taş boyutu 13,9±5,6 mm, ortalama operasyon süresi 52 dakika idi. Taş dağılımı şu şekildeydi: alt kaliks (%42,5), renal pelvis (%30,0), üst kaliks (%15,2) ve orta kaliks (%12,3). Toplam komplikasyon oranı %12,5 olup; minör komplikasyonlar (Clavien-Dindo Grade I-II) %11,4, orta komplikasyonlar (Grade III) %1,0 ve majör komplikasyonlar (Grade IV) %0,05 oranında görüldü. Çok değişkenli analiz, 15 mm'den büyük taş boyutu (odds ratio [OR]: 0,68, p<0,001), alt kaliks lokalizasyonu (OR: 0,75, p=0,004) ve multipl taşları (OR: 0,82, p=0,042) tedavi başarısının anlamlı öngördürücüleri olarak belirledi. Hasta memnuniyeti 10 üzerinden ortalama 8,4 olup, taşsızlık durumu ile güçlü korelasyon gösterdi (korelasyon katsayısı: 0,85, p<0,001). Sonuç: Retrograd intrarenal cerrahi, üst üriner sistem taşlarının tedavisinde yüksek etkinlik ve güvenlik göstererek farklı hasta gruplarında olumlu sonuçlar sağlamaktadır. Taş boyutu, lokalizasyonu ve multiplisitesi tedavi başarısını önemli ölçüde etkilemekte, standardize teknik ile komplikasyon oranları düşük kalmaktadır. Bu bulgular hasta seçiminin optimizasyonuna ve preoperatif danışmanlığın iyileştirilmesine yardımcı olabilir.
