Pyeloplasti Sonrası Böbrek Fonksiyonlarında Düzelme Olur mu? Düşük Renal Fonksiyonlu 13 Olgunun Değerlendirilmesi

Year 2018, Volume: 12 Issue: 1, 36 - 38, 01.04.2018

Abstract

Amaç: Üreteroplevik bileşke obstrüksiyonlu çocuk olgularda pyeloplasti sonrası fonksiyonel düzelme özellikle düşük fonksiyonlu böbreklerde halen tartışmalıdır. Literatürde opere edilen düşük renal fonksiyonlu olgularda iyileşme üzerine görüş birliği yoktur. Çalışmamızda düşük renal fonksiyonlu olgularda pyeloplasti sonrası iyileşme olup olmadığı amaçlandı.Gereç ve Yöntemler: Ocak 2009-Aralık 2015 tarihleri arasında opere edilen 80 olgudan 13 düşük fonksiyonlu olgunun preoperatif ve postoperatif diferansiye fonksiyonları, böbrek ön arka çapı ve parankimal kalınlığı değerlendirildi. Preoperatif ve postoperatif bulguların karşılaştırılması ile iyileşme olup olmadığına karar verildi.Bulgular: Diferansiye böbrek fonksiyonu %30’un altında olan 13 olgu değerlendirildi. 5 olgu antenatal hidronefrozi nedeni ile tanı alırken, 4 olgu üriner sistem enfeksiyonu sonrası, 4 olgu ise karın ağrısı semptomu ile tanı aldı. 13 olgudan 3’ünde postoperatif dönemde böbrek fonksiyonlarında %5’den fazla düzelme saptandı. Serimizde ameliyat öncesi ve sonrası böbrek fonksiyonları karşılaştırıldığında istatistiksel olarak anlamlı fark bulunmadı.Sonuç: Serimizdeki düşük fonksiyonlu UPJO nedeni ile pyeloplasti yapılan olgularda ameliyat sonrası bir değişiklik izlenmemiştir. Özellikle konservatif olarak izlenen hastalarda fonksiyon kaybı olmadan pyeloplasti yapılması önemlidir.

Is Differential Renal Function Improved After Pyeloplasty? Evaluation of 13 Cases with Low Differential Renal Function

Year 2018, Volume: 12 Issue: 1, 36 - 38, 01.04.2018

Abstract

Objective: Functional improvement after pyeloplasty in pediatric ureteropelvic junction obstruction (UPJO) is still debated, especially in poorly functioning kidneys. There is no consensus about the improvement of cases operated with poor renal function in the literature. In our study, we aimed to investigate whether there was an improvement after pyeloplasty in poor functioning cases. Material and Methods: Thirteen of the 80 cases operated between January 2009 - December 2015 with poor renal function were evaluated in terms of preoperative and postoperative differential functions, renal antero-posterior diameter and parenchymal thickness. We determined whether improvement was present by comparing preoperative and postoperative findings.Results: A total of 13 cases with differential renal function (DRF) less than 30% evaluated. Five of the cases were diagnosed after antenatal hydronephrosis, 4 after urinary tract infection and 4 following abdominal pain symptoms. Renal function improvement more than 5% was found in 3 of the 13 cases postoperatively. There was no statistically significant difference between preoperative to postoperative improvement of differential renal function in these series.Conclusion: There was no change in postoperative renal function in cases with low functional UPJO after pyeloplasty in our series. It is important to perform pyeloplasty before significant loss of function during the follow-up, especially in patients who are monitored conservatively

The publication language of Turkish Journal of Pediatric Disease is English.


Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 10 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.


The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
