Abstract

Retrograde urethrography (RUG) is a widely performed examination that involved irradiating radiosensitive organs like testes. It is therefore very important to know the amount x-ray dose imparted to individuals undergoing RUG cases.

To determine the imparted x-ray dose to patients undergoing VCUG/RUG cases at UMTH.

Aprospective study was conducted at UMTH using a prestige fluoroscopy machine with inbuilt DAP meter. The DAP meter was used to measure the imparted x-ray doses to 30 patients that came for RUG cases. Their ages ranged from 14years to 77years and weights ranged from 42kg to 73kg. The following technical factors were recorded: tube kilovoltage, focus-to-surface distance, screening time and miliamperage.

The minimum and maximum measured DAPs for the RUG cases were 27.72Gycm2 and 12.00Gycm2. The mean measured DAP for the RUG cases was 18.32Gycm2

The data was analyzed using SPSS version 16 statistical software.

The mean measured DAP was higher than reported in literature and also reference levels for UK, but still below those of Norway and NRPB. That meant they were practicing radiation protection in RUG examination but still need optimization to further reduce patient doses.
