All of the following are absolute contraindications for renal transplantation except:-
**Core Concept**
Renal transplantation is a complex procedure that requires careful patient selection to ensure optimal outcomes. Absolute contraindications are conditions that render a patient unsuitable for transplantation due to increased risk of complications or decreased likelihood of graft survival.
**Why the Correct Answer is Right**
The correct answer is not explicitly provided, but we can infer the context of the question. In general, absolute contraindications for renal transplantation include active malignancy, severe cardiovascular disease, severe pulmonary disease, and a history of non-adherence to medical treatment. These conditions can compromise the patient's ability to undergo and recover from the transplant surgery, or increase the risk of post-operative complications.
**Why Each Wrong Option is Incorrect**
**Option A:** Active malignancy is an absolute contraindication for renal transplantation, as it increases the risk of cancer recurrence in the transplanted kidney. Patients with active malignancy are typically required to achieve complete remission before being considered for transplantation.
**Option B:** Severe cardiovascular disease is also an absolute contraindication, as it increases the risk of cardiovascular complications during and after the transplant surgery. Patients with severe cardiovascular disease may require additional medical management or interventions to stabilize their condition before transplantation.
**Option C:** Severe pulmonary disease can be an absolute contraindication, depending on the severity and type of disease. Patients with severe pulmonary disease may have difficulty tolerating the immunosuppressive medications required after transplantation, or may be at increased risk of respiratory complications during and after surgery.
**Clinical Pearl / High-Yield Fact**
It's essential to note that each transplant center has its own set of criteria for patient selection, and what may be an absolute contraindication at one center may be a relative contraindication at another.
**Correct Answer:** D
