“…Giarenis et al. determined that the mean calculated effective dose of radiation in women undergoing VUDS was significantly correlated with BMI and fluoroscopy time . Their assessment was based on an estimated measurement of biological effects of irradiation.…”

“…This is less than an abdominal X‐ray (0.43 mSv) . The study by Giarenis et al was performed in the same unit as our study. It is common practice for us to screen those women in whom we suspect a urinary residual after pressure flow studies to check if they are empty at the end of the test.…”

Aims To test the different formulae to calculate the bladder volume using ultrasound; the accuracy of patients hearing/feeling “bubbles” at the end of urodynamics testing as a measure of being empty; and how good we are at estimating PVR using X‐ray at the end of video urodynamics testing. Methods This was a prospective cohort study. Using Sonosite 180 plus, bladder volumes were calculated as, height × width × depth × proportionality constant (0.52, 0.625, 0.65, and 0.7) Patients were asked whether the patient heard or felt “bubbles” at the end of the investigation. Each patient was fluoroscopically screened and the clinician estimated the volume and compared with single‐use catheter volume. Results A total of 85 patients were assessed. All four formulae were significantly correlated. The PC, 0.52, correlated best (r = 0.938, P < 0.001) with no significant difference with the actual volumes ( P = 0.275). The “bubbles test” had a positive predictive value of 93%. A video postvoid residual (PVR) estimation significantly correlated with catheterised bladder volume ( r = 0.842, P < 0.001). There was no significant difference between the estimated and actual bladder volumes ( P = 0.579). Conclusion This study showed that although all four formulae correlated significantly, the PC of 0.52 was the only formula without a significant difference from the actual volume. More work is needed to produce patient individualised PC. Our clinicians were able to accurately estimate the PVR on X‐ray. This study has identified the best formula to accurately estimate bladder volume and that video estimation along with the “bubbles” test can avoid unnecessary intervention.

“…As an example, the American College of Radiology provides a detailed description of the technique and links, to documents that list available contrast agents. Recent studies about the type of contrast media and the quality of imaging are rare but earlier fundamental research demonstrates that very dense medium may obscure details . Contrast agents have a different density compared to that of urine and or saline, which are usually applied for urodynamic measurements.…”

Aims Videourodynamics is the addition of imaging to invasive urodynamics and one of the methods to ensure objective diagnosis in persons with signs or symptoms of lower urinary tract dysfunction. This manuscript has the aim to outline the basics of the practice of videourodynamics and to elementary explain interpretation of the results. Methods Literature sources and expert opinion were arranged to provide the reader with an introductory overview of current knowledge. Results Videourodynamics was—like most diagnostics in health care—introduced on the basis of plausibility and expert conviction but has stood the test of time. Videourodynamics has, especially in patients with congenital or acquired neurogenic dysfunction of the lower urinary tract, undisputedly although not precisely quantifiable, added to (lower urinary tract) health care quality. Conclusion The manuscript summarizes the basic elements of indication, practice, and interpretation of videourodynamics.

Radiation exposure during videourodynamics in women

Abstract: This study reveals that women are exposed to relatively small amounts of radiation during VUDS. The use of fluoroscopy only without additional static radiographic images minimises exposure to a level consistent with the "as low as reasonably achievable" radiological principle.
