Aim This study was undertaken to compare the morphological differences between individuals with one functioning kidney and individuals with two functioning kidneys through the measurement of dimensions and stereological renal volume estimations. Materials and Methods The target sample consisted of patients who underwent an abdominal CT examination after attending Namık Kemal University’s Clinical Research and Application Center seeking medical attention. The volumetric estimations of CT images were based on the Cavalieri Principle. Results Of the overall study population, 22 had one healthy kidney and 30 had two healthy kidneys. Average renal dimensions were volume 159 cm3, length 10.7 cm, width 6.6 cm, and thickness 5 cm among anatomically normal individuals. The corresponding figures in the sole-functioning kidney group were volume 274 cm3, length 12 cm, width 7 cm, and thickness 6 cm. Conclusion Sole-functioning kidneys were longer, thicker, wider, and more voluminous compared with normal kidneys. We believe that the morphological differences between solitary and normal kidneys observed in this study in terms of dimensions and volume may represent a contribution to the existing literature that may assist in accurate volume and dimension estimations for clinical diagnosis and treatment of renal conditions
ÖZET
Amaç: Çalışmamız soliter böbrek ile sağlıklı iki böbreğe sahip bireylerde böbrek boyut ölçümleri ve stereolojik yöntemle böbrek hacim hesaplamasının yapılması ve iki grup arasındaki morfolojik farklılıkların belirlenmesi amaçlandı. Gereç ve Yöntem: Herhangi bir şikayet ile Namık Kemal Üniversitesi Araştırma ve Uygulama Merkezine başvurup, kontrast madde verilerek abdominal bilgisayarlı tomografisi (BT) çekilen hastalar çalışmaya dahil edildi. Hacim ölçümleri BT görüntüleri üzerinde Cavalieri prensibi ile yapıldı. Bulgular: Çalışmamıza katılan bireylerin 22’si soliter böbrek, 30’u sağlıklı iki böbreğe sahiptir. Normal grup için böbrek hacim ortalaması 159 cm3, böbrek uzunluğu 10.7 cm, genişliği 6.6 cm ve kalınlığı 5 cm olarak bulundu. Soliter böbrek grubunda ise, böbrek hacmi 274 cm3, uzunluğu 12 cm, genişliği 7 cm ve kalınlığı 6 cm bulundu. Sonuç: Soliter böbrek, normal böbreğe göre daha uzun, daha geniş, daha kalın ve hacimsel olarak da daha büyük olma eğilimindedir. Çalışmamızda soliter böbrek ile sağlıklı iki böbreğe sahip bireyler arasında, böbrek boyut ve hacim ölçümleri ile ilgili morfolojik farklılıklar ortaya konulmuştur. Elde edilen bu bulgular bazı böbrek hastalıklarının klinik tanı ve tedavisinde böbrek boyut ve hacminin doğru olarak değerlendirilmesi açısından literatüre katkıda bulunacağı düşüncesindeyiz.

ABSTRACT
Objective: This study was undertaken to compare the morphological differences between individuals with one functioning kidney and individuals with two functioning kidneys through the measurement of dimensions and stereological renal volume estimations.
Materials and Methods: The target sample consisted of patients who underwent an abdominal CT examination after attending Namık Kemal University’s Clinical Research and Application Center seeking medical attention. The volumetric estimations of CT images were based on the Cavalieri Principle.
Results: Of the overall study population, 22 had one healthy kidney and 30 had two healthy kidneys. Average renal dimensions were volume 159 cm3, length 10.7 cm, width 6.6 cm, and thickness 5 cm among anatomically normal individuals. The corresponding figures in the sole-functioning kidney group were volume 274 cm3, length 12 cm, width 7 cm, and thickness 6 cm.
Conclusions: Sole-functioning kidneys were longer, thicker, wider, and more voluminous compared with normal kidneys. We believe that the morphological differences between solitary and normal kidneys observed in this study in terms of dimensions and volume may represent a contribution to the existing literature that may assist in accurate volume and dimension estimations for clinical diagnosis and treatment of renal conditions.
