Urinary System Exam Questions Questions
Question 1 of 5
In USS (Ultra Sound Scan) of kidney, an image is said to be hypoechoic if
Correct Answer: B
Rationale: Hypoechoic on renal ultrasound means darker than surroundings less echo reflection (e.g., cysts). Brighter is hyperechoic dense tissue. Black without echoes is anechoic fluid-filled. Same as liver (isoechoic) varies kidney-specific. Darker hypoechoic appearance distinguishes it, critical for identifying lesions, unlike bright, fluid, or neutral patterns.
Question 2 of 5
In determining the anatomy of the anterior urethral structure, all of the following investigations are useful except
Correct Answer: D
Rationale: MRI isn't useful for anterior urethral strictures poor resolution for narrow lumens, better for soft tissue. RGU/MCU visualizes stricture length/location contrast-based. Ultrasound detects narrowing/thickness non-invasive. Urethroscopy directly views definitive. MRI's lack of utility distinguishes it, critical for practical stricture assessment, unlike effective imaging or scoping.
Question 3 of 5
All of the following statements regarding plasmacytoid variant of urothelial carcinoma of urinary bladder are true, EXCEPT?
Correct Answer: C
Rationale: Plasmacytoid urothelial carcinoma isn't chemoresistant responds to chemo (e.g., cisplatin), unlike true statement. Rare (<1%) correct prevalence. Intraperitoneal spread typical aggressive pattern. Eosinophilic cytoplasm histologic feature. Sensitivity to chemo distinguishes the error, key to its management, unlike rarity, spread, or pathology truths.
Question 4 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 5 of 5
All of the following are treatment options for high-risk localised prostate cancer, Except
Correct Answer: B
Rationale: Active surveillance suits low/intermediate-risk prostate cancer monitor, not treat high-risk (e.g., Gleason >7). Watchful waiting (palliative) fits comorbidities less aggressive. Prostatectomy + lymph node dissection and radiotherapy are curative high-risk standards. Surveillance's low-risk focus distinguishes it, key to risk-based management, unlike palliative or definitive options.
