Clinical photograph of another patient with cervical spinal cord injury and tetraplegia: This patient underwent ileal conduit urinary diversion since he had a urinary fistula from the prostatic urethra. Unfortunately, he developed stricture of distal ureters and required percutaneous nephrostomy drainage on both sides. The nephrostomy catheter emerges from the back. The location of the percutaneous nephrostomy catheter represents the traditional approach for draining a kidney or perinephric space, by inserting a catheter from the loin posteriorly. Compare the position of nephrostomy catheter of this patient with figure 4.
