Case 1. Left panel: Coronal section of non-contrast CT of abdomen revealed full bladder; Foley catheter was not seen within the urinary bladder. Right Top panel: Coronal section of CT of pelvis showed fluid distension of the membranous and prostatic urethra. Foley catheter was not seen in bladder or in proximal urethra. Right bottom panel: Coronal section of CT of pelvis revealed balloon of Foley catheter in the proximal penile urethra

Case 5. Top Left panel: CT abdomen axial section revealed moderate left hydronephrosis and hydroureter, and mild right hydronephrosis and hydroureter. Top Right panel: CT of abdomen and pelvis, axial section: Urethral catheter was not present within the bladder. Bladder was of small capacity and contained urine and gas. Bottom panel: CT pelvis, axial section revealed balloon of Foley catheter in the membranous urethra
