A micturating cystourethrography (MCU) examination is a specific radiological procedure that is performed under fluoroscopic screening to visualize the bladder by filling it with contrast material and to evaluate the urethral morphology during voiding. It is necessary to evaluate radiation dose during MCU examination since it involves radiosensitive organs such as the gonads. Radiation dose imparted to 109 patients undergoing MCU examination were measured using a dose-area product (DAP) meter. Patients were categorized into two groups based on whether filling of the bladder with contrast medium was done retrogradely (MCU) or by the suprapubic percutaneous route (SP-MCU). The DAP values to Group A (MCU) and Group B (SP-MCU) patients varied from 0.43 Gycm(2) to 9.26 Gycm(2) and 0.54 Gycm(2) to 9.87 Gycm(2), respectively. Reduction of radiation dose to patients was possible by the use of optimized exposure factors, precise collimation of X-ray beam, use of 0.2 mm copper filters and by acquiring images digitally.
Hemobilia is one of the complications that can occur after a transjugular liver biopsy. Various treatment options have been described for the management of this condition, including transarterial embolization and open surgery. We describe a patient who developed uncontrolled hemobilia after a transjugular liver biopsy that required a transvenous approach for embolization and treatment purposes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
