Üreter Taşının Boyut ve Lokalizasyonu ile Hidronefroz Derecesi Arasındaki İlişki

Çalışmamızın amacı üreter taşı olan hastalarda hidronefroz derecesi ile üreterdeki taşların boyutu ve yerleşimi arasında bir ilişki olup olmadığını bigisayarlı tomografi (BT) ile değerlendirerek araştırmaktır. Malatya Eğitim ve Araştırma Hastanesi'ne renal kolik şikayeti ile başvuran ve BT taraması yapılan 105 hasta bu çalışmaya dahil edildi. Hidronefroz, Fetal Üroloji Derneği tarafından geliştirilen derecelendirme sistemi kullanılarak değerlendirildi. Taş boyutları ise <5 mm, 5 – 10 mm ve ≥ 10 mm olarak belirlendi ve gruplara ayrıldı. Üreterlerin anatomik kısımlarına göre taşların yerleşimi proksimal - orta - distal olarak belirtildi. 61 (%58.1) hastada üreter distal kesiminde, 20 (%19) hastada orta üreter kesiminde, 24 (%22.9) hastada üreter proksimal kesiminde taş vardı. Taş boyutunun hidronefroz derecesine göre istatistiksel olarak anlamlı farklılık gösterdiği belirlendi (p<0.05). Proksimal, orta veya distal üreter segmentinde taş varlığı ile hidronefroz derecesi arasında istatistiksel olarak anlamlı bir ilişki yoktu (p=0.241). Üreter taşlarının boyutu arttıkça hidronefroz derecesi artarken, taşın üreterdeki yerleşiminin hidronefroz ile ilişkisi yoktur.

THE RELATIONSHIP BETWEEN THE SIZE AND LOCALIZATION OF THE URETERAL STONE AND THE DEGREE OF HYDRONEPHROSIS

The aim of our research is to evaluate whether there is a relationship between the degree of hydronephrosis and, the size and location of the stones in the ureter in patients with ureteral stones, with computed tomography (CT). 105 patients who applied to Malatya Training and Research Hospital with the complaint of renal colic and underwent CT scan were included in the study. Hydronephrosis was evaluated by using the system developed by the Society of Fetal Urology. Stone sizes were grouped as <5 mm, 5 – 10 mm, and ≥ 10 mm. The location of the stones were indicated as proximal - middle - distal according to the anatomical parts of the ureters. 61 (58.1%) patients had stones in the distal ureter, 20 (19%) had stones in the middle ureter, and 24 (22.9%) had stones in the proximal ureter. It was determined that the stone size showed significant difference according to the degree of hydronephrosis (p<0.05). There was no significant relationship between the stone location being in the proximal, middle or distal parts of the ureter and the degree of hydronephrosis (p=0.241). While, as the size of ureteral stones increases the degree of hydronephrosis increases, there is no relation with the location of the stone and hydronephrosis.
