“…RİRC sonrası bırakılan fragmanların uzun dönem sonuçları hakkında tartışmalar devam etmektedir (20,21). Özellikle alt kalikste bırakılan fragmanların -özellikle sistin taşı varlığında -tekrar taş oluşumuna neden olabileceği öne sürülmektedir (22).…”

ÖzetAmaç: Çocukluk çağı böbrek taşlarının tedavisinde retrograd intrarenal cerrahinin uygulanabilirliğinin gösterilmesi.Yöntemler: Kliniğimizde Aralık 2012-Şubat 2013 tarihleri arasında böbrek taşlarının tedavisi için retrograd intrarenal cerrahi uygulanan 14 hastanın bilgileri geriye dönük olarak incelendi. Tüm hastalarda işlem 7,5 Fr FlexX™ 2 fleksibl üreterorenoskop (Karl Storz GmbH & Co. KG, Tuttlingen, Germany) cihazı kullanılarak gerçekleştirildi. Hiçbir hastada üreteral akses kılıf kullanılmadı. Üretere giriş yapılamayan hastalarda pasif dilatasyon için 2 hafta süre ile çift j kateter takılarak işlem ertelendi. Taşlar lazer ile fragmante edildi ve iki milimetreden küçük fragmanlar kendiliğinden düşmesi için yerinde bırakıldı. Tüm hastalara işlem sonrası çift j kateter takıldı ve takiplerde üriner sistem ultrasonografisi ve direkt grafi kullanıldı. Bulgular: Ortalama hasta yaşı 7,5±2,47 (3-12 arası) yıldı. Hastalardan altısı kızdı ve altı hastada taş sağ taraftaydı. En büyük taş çapına göre ortalama taş boyutu 12,3±3,49 mm'ydi (8-20 arası). On hasta daha önce SWL tedavisi görmüştü. Ortalama operasyon süresi 33,5±6,9 (25-45) dakika, ortalama skopi süresi 45,3±15,4 (30-75 arası) saniyeydi. Hastanede kalış süresi 1,07±0,2 (1-2 arası) gündü. Hastaların hiçbirinde işlem esnasında komplikasyon gelişmedi. İşlem sonrası tüm hastalara çift j kateter takıldı ve iki hafta sonunda alındı. Tüm hastalarda taşsızlık sağlandı. Abs tractAim: To demonstrate the feasibility of retrograde intrarenal surgery (RIRS) in pediatric age group.Methods: Data of patients who underwent RIRS for the treatment of kidney stones were retrospectively analyzed. The procedure was performed using 7.5 Fr FlexX™ 2 flexible ureterorenoscope in all patients. Ureteral access sheath was not used in any patients. A double-j stent was inserted and the procedure was delayed for 2 weeks whenever access to the ureter was not possible. The stones were fragmented using laser and fragments smaller than 2 mm were left for spontaneous passage. Postoperative success was evaluated using ultrasonography and kidney, ureter and bladder (KUB) x-ray.Results: 14 patients with a mean age of 7.5±2.47 (range: 3-12) years were included. Male to female ratio was 8/6 and six patients had a stone on the right side. The mean stone size was 12. 3±3.49 (range: 8-20) mm. Of the patients, 10 had a history of unsuccessful shock wave lithotripsy (SWL) treatment. Mean operation and fluoroscopy screening times were 33.5±6.9 (range: 25-45) and 45.3±15.4 (range: 30-75) minutes, respectively. The median hospital stay was 1.07±0.2 (range: 1-2) days. No major complications were noticed during the operation. Double-J stents were removed on the 2 nd postoperative week and all patients were stone-free during the follow-up. Conclusion:RIRS can be performed safely and efficaciously in pediatric patients. (The Me di cal Bul le tin of Ha se ki 2015; 53:52-6)

“…In their study of 46 patients with post-URS renal stone fragments ≤4 mm, Rebuck et al suggested that approximately one in five (or 19.6%) patients experience a stone-related event in the 1.6 years after URS. 4 The remaining patients either become stone free through spontaneous passage or retain asymptomatic fragments of stable size. 4 However, studies with a larger patient population are required to determine the rate of SCRF after URS.…”

Objective: To investigate factors predicting spontaneous clearance of residual renal fragments after flexible ureteroscopy. Methods: Among 546 patients who underwent lithotripsy with flexible ureteroscopy, 81 had residual renal fragments, as determined by kidney-ureter-bladder films on postoperative day 1. The final outcome was determined at 3 months after the last flexible ureteroscopy session using non-contrast computed tomography. Patient characteristics and preoperative factors were analyzed using the unpaired t-test and 2 -test. Correlations between the possible predictive factors and the spontaneous clearance of residual renal fragments after flexible ureteroscopy were analyzed using a multivariate logistic regression model with backward selection. Results: Non-contrast computed tomography at postoperative month 3 showed that 33 cases (40.7%) had spontaneous clearance of residual renal fragments, whereas 48 (59.3%) showed non-clearance. Significant differences were found between these cases in terms of stone number, stone location, presence of lower pole calculi and preoperative stent placement. Multivariate assessment showed that stone number (P = 0.004), presence of lower pole calculi (P = 0.021) and presence of hydronephrosis (P = 0.024) were independent predictors of the spontaneous clearance of residual renal fragments after flexible ureteroscopy. Conclusions: Stone number, presence of lower pole calculi and presence of hydronephrosis are independent predictive factors of the spontaneous clearance of residual renal fragments after flexible ureteroscopy.
