These results state that although UPJ obstruction is an ongoing process, there is no correlation between the histological deterioration degree of the UPJ segment and the loss on renal function for both children and adults

Abstract

Objective: To compare changes in connective, neural and muscle tissues, and extracellular matrix in child and adult patients so that we can create a more objective view on the timing of surgery.Materials and Methods: Twenty-six patients, who were operated for ureteropelvic junction (UPJ) obstruction in our clinic between September 2014 and May 2016, were included in the study. For the evaluation of connective tissue, Masson’s trichrome staining was used. Muscle, extracellular matrix elements and neural tissue were evaluated with immunohistochemistry using alpha-smooth muscle actin (α-SMA), Tenascin C and S100, respectively. Microscopically, the tissues were scored according to their staining density (0: No staining; 1: Minor; 2: Moderate, 3: Dense).Results: There were 12 children and 14 adults in the study groups. The initial evaluation showed no statistically significant difference between studied tissue types with respect to staining density for all parameters (Masson: p=0.414, α-SMA: p=0.204, Tenascin-C: p=0.264, S100: p=0.534).There was no statistically significant correlation between staining density and renal function percentage of the affected kidney (Masson: r=0.454, p=0.051 - α-SMA: r=-0.323, p=0.177 - Tenascin-C: r=0.290, p=0.229 - S100: r=-0.080, p=0.744).Conclusion: Our preliminary study showed some structural changes between adult and child patients but there is no statistically significant difference between the groups with respect to staining density scores. These results state that although UPJ obstruction is an ongoing process, there is no correlation between the histological deterioration degree of the UPJ segment and the loss on renal function for both children and adults

Özet

Amaç: Cerrahi zamanlaması üzerine daha objektif bir görüş oluşturabilmek için çocuk ve erişkin hastaların bağ, sinir, kas dokuları ve ekstraselüler matriks proteinlerindeki değişiklikleri karşılaştırmaktır.Gereç ve Yöntem: Kliniğimizde Eylül 2014-Mayıs 2016 tarihleri arasında üreteropelvik bileşke (UPB) darlığı nedeniyle opere edilen 26 hasta çalışmaya dahil edildi. Bağ dokusu değerlendirmesi için Masson trikrom boyama kullanıldı. Kas, ekstraselüler matriks elemanları ve sinir dokusu sırasıyla alfa smooth-muscle aktin (?-SMA), Tenascin C ve S100 kullanılarak immünhistokimyasal olarak değerlendirildi. Mikroskopik dokular boyama yoğunluğuna göre skorlandı (0: Boyanma yok, 1: Minör, 2: Orta, 3: Yoğun).Bulgular: Çalışma grubunda 12 çocuk ve 14 yetişkin vardı. İlk değerlendirme, incelenen doku tiplerinde, tüm parametreler için boyama yoğunluğuna göre istatistiksel olarak anlamlı bir fark olmadığını gösterdi (Masson: p=0,414, ?-SMA: p=0,204, Tenascin-C: p=0,264, S100: p=0,534). Etkilenen böbreklerin boyanma yoğunluğu ile renal fonksiyon yüzdesi arasında istatistiksel olarak anlamlı bir korelasyon yoktu (Tenascin-C: r=0,290, p=0,229 - S100: r=-0,080, p=0,744).Sonuç: Çalışmamız yetişkin ve çocuk hastalar arasında bazı yapısal değişiklikler olduğunu göstermiş ancak boyama yoğunluğu puanlarında gruplar arasında istatistiksel olarak anlamlı bir fark bulunamamıştır. Bu sonuçlar, UPB darlığının devam eden bir süreç olduğunu göstermekle birlikte, UPB segmentinin histolojik bozulma derecesi ile hem çocuklarda hem de erişkinlerde böbrek fonksiyonlarındaki kayıp arasında bir korelasyon olmadığını ortaya koymaktadır
