Öğe Flexible Ureterorenoscopy for the Treatment of Kidney Stone Within Pelvic Ectopic Kidney(Elsevier Science Inc, 2014) Bozkurt, Omer Faruk; Tepeler, Abdulkadir; Sninsky, Brian; Ozyuvali, Ekrem; Ziypak, Tevfik; Atis, Gokhan; Daggulli, MansurOBJECTIVE To present the outcomes of flexible ureterorenoscopy (F-URS) and laser lithotripsy for the treatment of calculi within pelvic ectopic kidney (PEK). PATIENTS AND METHODS We retrospectively reviewed the medical records of 26 patients with calculi in PEK treated with F-URS in 5 referral hospitals between 2010 and 2013. Patient demographics and stone characteristics (age, sex, body mass index, stone size, location, history of shock wave lithotripsy or kidney surgery), and perioperative measures (duration of operation, fluoroscopic imaging, and hospitalization and success and complication rates) were reviewed. RESULTS A total of 26 patients with mean age of 41.1 +/- 15.8 years (7-72 years) were included in the study. The mean stone size was 17.0 +/- 5.1 mm (10-28 mm). The mean procedure and fluoroscopy times were calculated as 52.1 +/- 27.7 minutes (30-120 minutes) and 54.8 +/- 48.9 seconds (10-180 seconds), respectively. The mean length of hospital stay was 2.7 +/- 1.8 days (1-9 days). Treatment was deemed successful in 22 patients (84.6%). Ureteroscopy failed in 4 patients (15.4%) due to impaired passage of fragments (n = 3) or inability to reach the stone secondary to the location in an isolated lower calyx (n = 1). Minor postoperative complications were observed in 5 patients (19.2%; persistent hematuria [n = 1], fever [n = 1], renal colic [n = 2], and urinary tract infection [n = 1]). No severe complications or mortality occurred. CONCLUSION Our results suggest that F-URS is a safe and effective minimally invasive treatment modality for small-and medium-sized stones in PEK.

We performed a retrospective analysis of 136 patients (140 renal units) who underwent micro-PNL for renal stones between September 2011 and February 2013 in four referral hospitals in Turkey. The selection of treatment modality was primarily based on factors such as stone size and location. In this study, we analyzed patient- and procedure-related factors. The mean age of patients in this study was 28.7 +/- A 20.6 (1-69) years, and the mean stone size was 15.1 +/- A 5.15 (6-32) mm. Conversion to mini-PNL was required in 12 patients. All interventions were performed with the patient in the prone position, except for the 3-year-old patient with the pelvic kidney who was placed in the supine position. The mean hospital stay was 1.76 +/- A 0.65 (1-4) days, and the mean drop in the hemoglobin level was 0.87 +/- A 0.84 (0-4.1) mg/dL. One of our patients required transfusion. Ureteral J stent was implanted in nine (6.43 %) patients because of residual stones. Seven (6.43 %) patients complained of postoperative renal colic which was managed conservatively. Abdominal distension related to extravasation of the irrigation fluid was observed in three patients (2.19 %). There were no other postoperative complications. An overall success rate of 82.14 % was achieved. Micro-PNL can be effectively and safely used for small and moderate kidney stones resistant to shock wave lithotripsy or as an alternative to other minimally invasive treatment methods.Öğe INITIAL REPORT OF 'MICROPERC' IN THE TREATMENT OF PAEDIATRIC KIDNEY STONES(Mary Ann Liebert, Inc, 2012) Silay, Mesrur Selcuk; Tepeler, Abdulkadir; Atis, Gokhan; Piskin, Mesut; Sancaktutar, Ahmet Ali; Gurbuz, Cenk; Penbegül, Necmettin[Abstract Not Available]Öğe Initial report of microperc in the treatment of pediatric nephrolithiasis(W B Saunders Co-Elsevier Inc, 2013) Silay, Mesrur Selcuk; Tepeler, Abdulkadir; Atis, Gokhan; Sancaktutar, Ahmet Ali; Piskin, Mesut; Gurbuz, Cenk; Penbegül, NecmettinBackground/Purpose: To report the first technical feasibility and safety of microperc in the treatment of pediatric nephrolithiasis. Methods: A multicenter prospective trial was initiated and microperc was performed in 19 children from four different centers. In all cases, 4.85-Fr all-seeing needle was used to access the collecting system under direct vision. Stone fragmentation was performed using a 200-mu m holmium: YAG laser fiber either through the same needle sheath or an 8-Fr microsheath. Patient-and procedure-related factors and perioperative and postoperative parameters were analyzed. Results: The mean age of the children was 7.5 +/- 4.4 years. Mean stone size was 14.8 +/- 6.8 mm. Conversion to Mini-PNL was required in two patients because of optical default in one and the high stone burden in the other. The mean hospital stay was 1.8 +/- 0.8 days and the mean hemoglobin decrease was 0.1 mg/dl. The overall stone-free rate at 1 month was 89.5%. In one patient with obstructed ureteropelvic junction, intravasation of the irrigation fluid has led to abdominal distention and managed with percutaneous drainage intraoperatively. No other postoperative complication was recorded and no ancillary procedure was required. Conclusions: Microperc is a safe and effective procedure in the treatment of pediatric kidney stones.

We believe this comprehensive, national prospective study will provide valuable insights for clinicians planning empirical treatment for uncomplicated urinary tract infections.
