Final answer:
Suprapubic placement is the least damaging urinary diversion procedure for adolescent body image.
Step-by-step explanation:
The urinary diversion procedure that is typically considered the least damaging to the body image of the adolescent is suprapubic placement. Suprapubic placement involves inserting a catheter through the abdominal wall directly into the bladder, allowing urine to drain externally. This procedure may be preferred by adolescents as it avoids the need for a visible stoma or an external urine bag, which can impact body image.
