Urinary System Exam Questions Questions
Question 1 of 5
All of the following statements regarding focal therapy for renal tumors are true, EXCEPT:
Correct Answer: C
Rationale: Radiofrequency ablation (RFA) ablates tumors >50% size reduction isn't typical; necrosis, not shrinkage, is goal false. <3 cm suitability true, small tumors ideal. Less demanding than partial nephrectomy correct, minimally invasive. Cryoablation at -40°C accurate, lethal threshold. Lack of significant shrinkage distinguishes RFA's effect, key to focal therapy outcomes, unlike size, ease, or temp truths.
Question 2 of 5
The nerve supply of the Adrenal gland is
Correct Answer: A
Rationale: Adrenal medulla receives sympathetic innervation (splanchnic nerves) triggers catecholamine release (e.g., epinephrine). Cortex lacks direct nerves hormonal control (ACTH). Parasympathetic doesn't supply adrenal vagal elsewhere. Medulla's sympathetic link distinguishes it, key to fight-or-flight, unlike cortex or parasympathetic errors.
Question 3 of 5
The most common presentation of Ureterocele in either sex is
Correct Answer: B
Rationale: Ureterocele commonly presents with urinary infections obstruction/stasis breeds bacteria (e.g., E. coli) in kids/adults. Mass is rare large ureteroceles only. Urethral mass fits prolapse uncommon. VUR is associated, not presenting secondary. Infection's frequency distinguishes it, critical for ureterocele diagnosis, unlike rare or related findings.
Question 4 of 5
Which investigation is not recommended for assessment of bothersome lower urinary tract symptoms?
Correct Answer: D
Rationale: Ultrasound abdomen/pelvis isn't recommended for initial LUTS assessment optional for complications (e.g., hydronephrosis), not routine. IPSS quantifies symptoms essential. DRE checks prostate size standard. Uroflow measures obstruction key. USS's secondary role distinguishes it, critical for guideline-based evaluation, unlike primary tools.
Question 5 of 5
The pneumoperitoneum pressure selected for performing Robotic and Laparoscopic procedures is
Correct Answer: C
Rationale: 15 mm Hg is standard pneumoperitoneum pressure for robotic/laparoscopic procedures balances visibility and safety (e.g., renal surgery). 5 mm Hg is too low poor exposure. 10 mm Hg suits pediatrics insufficient for adults. 20 mm Hg risks hypercapnia/ischemia excessive. 15 mm Hg distinguishes it, critical for optimal operative field without undue risk, unlike under- or over-pressurized options.
