PurposeDetermining the ideal length of a ureteric stent is important to avoid complications associated with stent placement. Clinically, most urologists usually choose the length of a ureteric stent according to the patient’s height. On the basis of a Chinese population study, a 22 cm ureteric stent has been recommended for patients smaller than 175 cm. We evaluated the appropriateness of this recommendation in Korean patients.
Materials and MethodsA total of 70 patients who were smaller than 175 cm and who underwent ureteroscopic lithotripsy and ureteric stent insertion were studied. The appropriateness of the stent length was determined on the basis of plain film findings. Patient discomfort was measured by use of a visual analogue scale (VAS) before the removal of the ureteric stent.
ResultsIn 29 patients with a 22 cm ureteric stent, 21 patients (72.4%) had an appropriate ureteric stent length and the mean VAS was 4.1. In 36 patients with a 24 cm ureteric stent, 20 patients (55.6%) had an appropriate ureteric stent length and the mean VAS was 4.0. Among 5 patients with a 26 cm ureteric stent, 1 patient (20%) had an appropriate ureteric stent length and the mean VAS was 5.4.
ConclusionsIn Korean patients smaller than 175 cm in height, a 22 cm ureteric stent was an appropriate length.
