Multiple Choice Questions On Urinary System Questions
Question 1 of 5
A 34 year male has road traffic accident. His vital signs are stable and there are no significant external injuries. CT scan revealed deep parenchymal lacerations in the right kidney. The next step is
Correct Answer: C
Rationale: Delayed imaging assesses pelvicalyceal integrity (e.g., urine leak) in stable deep lacerations guides conservative vs. intervention. Open repair risks unnecessary surgery stability favors watching. Embolization suits vascular injury, not parenchymal mismatch. Nephrectomy is extreme preservation priority. Delayed imaging distinguishes it, key to defining injury extent, unlike premature or radical steps.
Question 2 of 5
All of the following statements regarding histopathological feature of spermatocytic seminoma are correct, EXCEPT
Correct Answer: C
Rationale: Spermatocytic seminoma lacks lymphocyte infiltration unlike classic seminoma, it's stroma-poor. Glycogen-negative true, lacks storage. PLAP-negative correct, not embryonal marker. Round nuclei accurate, typical feature. Absent lymphocytes distinguish it, key to its unique histopathology (older men, benign), unlike glycogen, PLAP, or nuclear truths.
Question 3 of 5
A 68 years old male presented with gross painless hematuria for last 7 days. On evaluation 3.5 cm × 2.5 cm growth detected on base of urinary bladder. Post TURBT histopathological report suggestive of non-muscle invasive micropapillary variant of urothelial carcinoma. Metastatic workups were negative. The next best treatment option for him is
Correct Answer: B
Rationale: Micropapillary urothelial carcinoma (non-muscle-invasive) warrants radical cystectomy aggressive, high recurrence/progression risk despite NMIBC status. BCG is standard for typical NMIBC insufficient here. Neoadjuvant chemo suits muscle-invasive overkill now. Re-TURBT assesses residual, but micropapillary's behavior pushes cystectomy. Radical approach distinguishes it, key to curbing this variant's potential, unlike conservative or staging options.
Question 4 of 5
All of the following statements regarding micropapillary variant of urothelial carcinoma of urinary bladder are true, EXCEPT
Correct Answer: A
Rationale: Micropapillary urothelial carcinoma lacks strong female predominance slight male bias, aggressive in both false. 5-year survival ~50% true, poor prognosis. Surgery (cystectomy) is best correct. 0.7-2.2% prevalence accurate rarity. No female dominance distinguishes the error, key to its epidemiology, unlike survival, treatment, or frequency truths.
Question 5 of 5
Which is true about post obstructive diuresis?
Correct Answer: B
Rationale: Post-obstructive diuresis is >200 mL/hr for 2+ hours physiologic response to relieve backlog post-obstruction (e.g., BPH relief). >100 mL/hr is normal too low. >400/500 mL/hr is excessive pathologic threshold, not standard. 200 mL/hr distinguishes it, critical for monitoring fluid loss, unlike normal or extreme rates.
