Abstract

Objectives: Evaluate the benefits of ultrasound for instrument positioning in high-dose brachytherapy. Patients and methods: Retrospective descriptive study, 48 patients diagnosed with cervical cancer stages IB2 -IIIB were treated with a combination of Cisplatin chemotherapy, external radiation and high-dose brachytherapy at K Hospital from May 2019 to December 2019. Result: Characteristics of the study group: Average age was 49.9 ± 9.2; The most common age group is 40-59 years old (64.6%). The rate of uterine perforation is 4.2% (2/48 patients). There were 14.6% (7/48 patients) of instruments placed off axis. The most common reason for ultrasound conversion is not finding the entrance (difficult to place) 65.8% (25 procedures), the rate of uterine misalignment is 18.4% (4 patients). Statistics from 34 patients who had routine brachytherapy showed that 14 patients (accounting for 41.2%) did not have enough urine in the bladder after the procedure, and 20 patients (58.8%) had enough urine in the bladder. There are no serious complications of complications, just care and internal medicine is enough.
