Urinary System Exam Questions Questions
Question 1 of 5
Which of the following statement is INCORRECT regarding Lumbo dorsal fascia?
Correct Answer: D
Rationale: Posterior lamella of lumbodorsal fascia covers, not separates, erector spinae from quadratus lumborum middle layer does that, incorrect. Layers merge near 12th rib true anatomy. Anterolateral fusion with transversus abdominis holds correct. Spinous origin of posterior lamella is accurate structural base. Separation error distinguishes incorrect statement, key to fascial anatomy, unlike true descriptions.
Question 2 of 5
Which of the following statement is correct regarding multichannel Urodynamics?
Correct Answer: D
Rationale: Multichannel urodynamics is the most accurate tool for incontinence measures pressures (Pves, Pabd, Pdet derived), flow, and EMG, pinpointing causes (e.g., detrusor overactivity). Not all need it initial trials suffice for some. It assesses upper tract risk (e.g., high pressure) false to deny. Pdet is calculated, not direct minor flaw. Accuracy distinguishes it, critical for complex incontinence, unlike overuse, risk denial, or measurement errors.
Question 3 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 4 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 5 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.
