“…With recent technological improvements, although flexible ureteroscopy has gradually become a common treatment for multiple renal calculi, the value of flexible ureteroscopy in multiple renal calculi lacks sufficient evidence-based research [ 11 ]. In order to serve as a reference for the clinical selection of reasonable surgical methods, our study covered several aspects.…”
Objective. Renal calculi are a common type of urological calculi and are associated with morbidity. This study was aimed at exploring the effect of flexible ureteroscopy and nephroscopy on stone removal in patients with multiple renal calculi. Method. This randomized controlled trial included a total of 78 cases with multiple renal calculi in our hospital. The patients were randomly divided into the study and control groups and treated with flexible ureteroscopy and percutaneous nephrolithotomy with pneumatic ballistics, respectively. The surgery condition, levels of prostaglandin F2α (PGF2α), prostaglandin E2 (PGE2), keratocyte growth factor (KGF), renal function indices, and the incidence of complications were analyzed before and after surgery in the two groups. Result. The operation time, the postoperative analgesia pump application time, one-time stone removal rate, the intraoperative blood loss, and hospital stay of the study group were significantly lower than those of the control group. Postsurgery, the levels of PGE2, PGF2α, and KGF in the study group were significantly lower than those in the control group. The serum levels of SCR, BUN, and NGAL in the study group were significantly lower than those in the control group. In addition, the incidence complications in the study group were significantly lower. Conclusion. Flexible ureteroscopy and laser lithotripsy under nephroscopy were equally effective against multiple renal calculi. Flexible ureteroscopy reduced surgical trauma without affecting renal function and had a low incidence of complications.

“…Alt polün anatomik yönleri, özellikle kalikslerin dağılımı, infundibulum ile renal pelvis arasındaki açı, infundibulum uzunluğu ve infindibulum genişliği dikkate alındığında, tedavinin başarısını belirlemek için çok önemlidir (9). Bu ölçümler genellikle intravenöz piyelografi (İVP) ile yapılsa da İVP ve BT ile yapılan ölçümlerin korele olduğu daha önce gösterilmiştir (10).…”
Amaç: Böbrek taşı nedeniyle retrograt intrarenal cerrahi uygulanan olgularda taşsızlık elde etmede etkili olan faktörleri saptamayı amaçladık.Gereç ve Yöntemler: Ocak 2021- Temmuz 2021 tarihleri arasında kliniğimizde retrograt intrarenal cerrahi (RİRC) uygulanan 160 olgunun verilerini retrospektif olarak analiz ettik. Hastaların demografik özellikleri, bilgisayarlı tomografi (BT) görüntüleri üzerinden ölçümü yapılan taş ve böbrek kalisiyel anatomisi ile ilgili parametreleri, üreter erişim kılıfı (ÜEK) kullanılma durumu ve cerrahi süre analiz edildi. Postoperatif 1.ayda direkt üriner sistem grafisi (DÜSG) veya BT görüntülerindeki rezidü taşın 2 mm’den küçük olması veya hiç taş olmaması cerrahi için başarılı kabul edildi. Hastalar taşssızlık durumuna göre taşsız (Grup1) ve rezidü taşa sahip (Grup 2) olmak üzere iki gruba ayrıldı. Ayrıca böbrekteki taş lokalizasyona göre alt pol olan (45 derece ve üstü ile altı) ve olmayan diye alt grublara ayrıldı. Gruplar operasyon sonrası rezidü varlığına göre kıyaslandı. Bulgular: Grup 1 ve Grup 2 için cinsiyetin dağılımları, vücut kitle indeksi (VKİ), taraf, ÜEK kullanımı, opasite durumu, infindibulopelvik açı (İPA) ve infundibuler uzunluk için fark yoktu (p>0,05). Taşssız olan Grup 1’de infundibuler genişlik daha fazla idi (p>0,021). Birden fazla taşı olanlarda rezidü, tek taşı olanlara göre fazla idi (p>0,048). Taş hacmi ve taş dansitesi için taşsızlık üzerine etkileyici sonuç bulmadık. Böbrekteki lokalizasyona göre alt pol olanlarda rezidü fazlaydı (p>0,001). Ancak alt pol taşları olanlarda 45 derece üstü ve altı olanlar arasında fark yoktu (p>0,050). Sonuç: Retrograd intrarenal taş cerrahisi tedavisinde, birden fazla taşın olması, alt pol taşın olması, infundibüler genişliğin az olması taşsızlığı olumsuz etkileyen faktörler olarak öngörülebilir.
