case_images: Multiplanar reconstruction with maximum intensity projection CT image of the lower urinary tract of the cat, 4 mins after intravenous contrast administration. Insertion of the right ureter (arrows) was seen at the urinary bladder neck region with contrast extending distally along the urethra (arrowheads) before filling the bladder, indicating right intramural ectopic ureter. UB = urinary bladder

case_images: This finding suggested a likely right EU (Figure 1).
case_images: Ultrasound image of intramural right ectopic ureter. Indicated by the arrows, an echoic tubular structure with a thin hyperechoic wall-like structure is seen cranially from the urinary bladder neck and extends caudally along the proximal urethra. This tubular structure can be followed cranially to converge with the right ureter entering the region of the urinary bladder neck. EU = ectopic ureter

case_images: A focal urinary tract ultrasound suggested the right EU was intramural (Figure 2).
case_images: Right ureteral opening identified during cystoscopy. The right ureter was identified in the mid to distal urethra. A hydrophilic coated guidewire was inserted into the ureteral opening as depicted in this picture

case_images: fig3-20551169231220248
case_images: The right ureteral opening was identified in the mid to distal urethra (Figure 3), whereas the left ureteral opening was identified in the proximal urethra (Figure 4).
case_images: Left ureteral opening identified with cystoscopy. The arrow is pointing to the left ureteral opening located in the proximal urethra

case_images: The right ureteral opening was identified in the mid to distal urethra (Figure 3), whereas the left ureteral opening was identified in the proximal urethra (Figure 4).
case_images: Urethra after laser ablation. The black arrows are pointing to the cut edge after laser ablation of the right ureter. The white arrow is pointing to the tract left behind after laser ablation of the left ureter

case_images: These steps were repeated to correct the right EU (Figure 5). The vaginal septum was corrected using laser ablation as well. The cat recovered well from anesthesia with no immediate post-procedural complications.
