Conditions

Ureter Stone

Brief summary

Patients (female, male, or queer) with ureteral stones (smaller than 1 cm at the widest diameter of the stone) without pyonephrosis, urinary sepsis, or untraceable pain will be enrolled into the study. Ureteral width at the smallest area of the ureter (in most cases UV junction) will be noted during regular ultrasound scans. The ratio of ureteral width to the stone diameter will be correlated with the spontaneous stone passage.

Interventions

PROCEDUREUltrasound

Enrolled patients underwent ultrasound scan of kidneys, ureters, and the bladder.
