On the survey images, a urinary catheter is present in the urethra and the region of the urinary bladder. The bladder is not visualized, and there is poor peritoneal detail. There is subluxation of the left sacroiliac joint, with cranial displacement of the ilium with respect to the sacrum. There is asymmetry of the pelvic symphysis with a step defect between the left and right pubis. There is a radiolucency extending across the left ischiatic table. The caudoventral abdominal body wall is thickened and indistinct, with an angular mineral opacity superimposed over the soft tissues of this region.
A urethrogram was performed with gradual retraction of the urinary catheter into the urethra. The contrast medium immediately distributes into the peritoneal space, and the bladder is not visible.
An apical bladder rupture was identified and repaired at surgery.
What contrast was used for this? Iohexol?
Thanks!
Yes, water soluble nonionic contrast medium is the best choice in the urinary tract.
