Agree or disagree: In CKD patients with scarred, small kidneys (<9 cm), aggressive diagnostic or therapeutic measures are generally not pursued.

Explanation:
The main idea being tested is that kidney size reflects how much irreversible damage has occurred. When kidneys become scarred and shrink to under about 9 cm in an adult, this signals long-standing, irreversible parenchymal loss with little remaining renal reserve. In this situation, pursuing aggressive diagnostic workups or treatments is unlikely to restore function or significantly alter the course of CKD, and it increases the risk of procedure-related harm. Clinicians tend to shift toward approaches focused on comfort, symptom control, and planning for renal replacement therapy based on the patient’s goals and overall prognosis, rather than pushing for invasive interventions that are unlikely to help. There can be rare exceptions if a reversible issue is suspected or a diagnosis would meaningfully change management, but in general small, scarred kidneys with advanced CKD justify a more conservative, nonaggressive approach.
