Imaging findings OR Procedure details
This novel RUG technique substitutes the utilization of a Foley catheter for a 21 Gauge IV cannula and clamp (Figure 1) to overcome the shortcomings of the Foley catheter method. It enables maximum traction, and thus elongation of the anterior urethra to identify strictures including its precise location and length. The size of the IV cannula in comparison to the Foley catheter minimizes patient discomfort allowing for maximum traction and allows for RUGs to be performed for patients with distal urethral abnormalities that otherwise would be precluded due to the size of the Foley catheter or obscured by the Foley catheter and its balloon. Manipulation of the penis is facilitated by the clamp, providing a second degree of control into a position that is parallel to the image receptor, increasing the ability to obtain a technically adequate RUG (Figure 2).
