case_images: CT image in 2013 shows left ureteral effusion (grey arrow), with calculus completely obstructing the ureter (white arrow; the low-density shadow around the calculus is considered as ureteral wall edema caused by the calculus).

case_images: In 2013, he underwent a CT scan for his abdominal pain, which revealed a left ureteral calculus, left ureteral, and left renal pelvis hydronephrosis (Figures 1 and 2).
case_images: CT image in 2015 shows left renal atrophy, renal cortex thinning (white arrow), and right kidney compensatory hypertrophy (black arrow).

case_images: His left kidney had atrophied and a thinned cortex that was shown on CT images (Figure 3).

case_images: B-mode ultrasound revealed a fluid sonograph shadow in the pelvic cavity (Figure 4).
case_images: A mixed signal shadow can be seen as a quasi elliptical on MR T2WI (white arrow), located between the rectum and bladder. The left high signal shadow (hollow in middle, black star) is the water bag of the Foley catheter, located in the bladder at the internal urethral orifice.

case_images: The follow-up MRI and the B-mode ultrasound after 3 days of treatment revealed that the shadow clearly contracted (Figures 6 and 7), but mixed signal shadow remained in the MRI images, and a hyperechoic shadow was shown in its center in B-mode ultrasound, which implied that the original abscess significantly shrank.
case_images: The follow-up B-mode ultrasound in 2015 revealed mixed sonograph shadow, with hyperechoic in its center, posterior to the bladder.
