Which is not an absolute contraindication for adult renal transplantation?

Correct Answer: B

Rationale: BMI >30<35 isn't absolute relative risk (surgery complications), manageable. Morbid obesity (>35) is absolute high perioperative risk. BMI <20 signals malnutrition poor healing, absolute. Anuria (no urine) reflects ESRD transplant candidate, not barrier. Moderate BMI distinguishes it, critical for candidacy flexibility, unlike severe or extreme limits.

Correct Answer: D

Rationale: IPSS assesses LUTS frequency, urgency, incomplete voiding (storage/voiding symptoms) but not dysuria (pain), which is infection/inflammation-related, not BPH-focused. Frequency (how often), urgency (sudden need), and incomplete voiding (residual) quantify obstruction/irritation. Dysuria's exclusion distinguishes IPSS, critical for symptom scoring, unlike pain inclusion.

Correct Answer: D

Rationale: Morbid obesity isn't a contraindication for laparoscopic surgery challenging but feasible with adjustments (e.g., trocar placement), not absolute. Hemodynamic instability risks collapse absolute no. Intestinal obstruction causes distension unsafe pneumoperitoneum. Increased intracranial pressure worsens with COâ‚‚ insufflation dangerous. Obesity's manageability distinguishes it, key to surgical candidacy, unlike life-threatening or mechanical barriers.

Correct Answer: C

Rationale: Uric acid concentrates in urine as a waste product, unlike glucose (reabsorbed), sodium (regulated), or phosphate (variable). This highlights excretory priority, vital for purine metabolism, contrasting with reabsorbed substances.

Correct Answer: C

Rationale: Proximal convoluted tubule (PCT) reabsorbs ~65-70% of filtrate (glucose, Na+), not loop, DCT (fine-tuning), or glomerulus (filtration). This highlights PCT dominance, vital for bulk reabsorption, contrasting with later segments.
