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

Abstract

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.
