Öğe Does prematurity indicate poor prognosis in the treatment of infant ureteropelvic junction obstruction?(2019) Huseynov, Mirzaman; Emre, Senol; Ozcan, Rahsan; Bakir, Ayten Ceren; Canpolat, Nur; Elicevik, MehmetAim: To evaluate the outcomes of management of ureteropelvic junction obstruction in premature patients by comparing them to a group of non-premature. Material and Methods: We reviewed the medical records of 102 patients with isolated hydronephrosis which were referred from pediatric nephrology outpatient clinic or those who admitted directly to pediatric urology clinic under one year of age between the years of 2005 and 2016. Two groups were set up; premature and term. The gestational age, sex, management for ureteropelvic junction obstruction, complications were recorded. Chi-Square, Fisher’s and Mann-Whitney-U tests were used for statistical analyzes. Results: There were 92 patients in the term group and 10 in the premature group. All patients were operated. Preoperative symptoms such as pyonephrosis, renal calculi, and hypertension were relatively common in the premature group. Preoperative low function, postoperative loss of function, and poor outcome were statistically more common in premature patients. Conclusion: In our limited experience, prematurity is an independent factor associated with UPJO, and it may indicate a poor prognosis. We advocate that this issue should be considered in practice.Öğe Hemolytic uremic syndrome outbreak in Turkey in 2011(Turkish J Pediatrics, 2013) Ekinci, Zelal; Candan, Cengiz; Alpay, Harika; Canpolat, Nur; Akyuz, Sare Gulfem; Gunduz, Zubeyde; Dursun, IsmailThe aim of this retrospective multicenter study was to define the epidemiological and clinical features and prognostic factors of the first diarrhea-related hemolytic uremic syndrome (D+HUS) outbreak in Turkey in 2011. All pediatric nephrology centers in Turkey were asked about D+HUS patients via e-mail. Seventy D+HUS patients (median age: 5.7 years) participated. The seasonal peak was around the 7th, 8th and 9th months with 44 cases, centered in the east Marmara region. No causative agent could be identified. The rate of neurological complications and mortality was 21.4% and 4.2%, respectively. Eculizumab was used in four cases. Two of them had severe neurological complications despite plasma exchange. Elevated polymorphonuclear leukocyte count during hospital admission was the predictor of both severe disease and poor outcome. Duration of prodrome was the predictor of poor outcome (p<0.05). In conclusion, the median age of the affected children was greater than in the previous reports, while clinical features and outcome were similar.Öğe POST-TRANSPLANT LYMPHOPROLIFERATIVE DISEASE IN PEDIATRIC KIDNEY TRANSPLANT RECIPIENTS IN TURKEY(Springer, 2022) Dursun, Ismail; Koyun, Mustafa; Canpolat, Nur; Poyrazoglu, Hakan; Bakkaloglu, Sevcan; Comak, Elif; Gulmez, Ruveyda[Abstract Not Available]
