Urinary System Questions Questions
Question 1 of 5
Renin secretion is increased by the following, Except:
Correct Answer: D
Rationale: Renin rises with hypovolemia, DCT hyponatremia (macula densa), and sympathetic input not PCT (no sensing role). This distinguishes renin triggers, vital for blood pressure regulation, contrasting with tubular mislocation.
Question 2 of 5
Which of the following statement about Genito Urinary Tuberculosis (GUTB) is INCORRECT?
Correct Answer: D
Rationale: Optimal surgery for GUTB is 4-6 weeks post-therapy, not 1 week allows inflammation reduction, incorrect timing. GUTB is second to pulmonary in developing areas true prevalence. Kidney involvement is ~80% primary site. Urine AFB culture is gold standard specific diagnosis. Delayed surgery distinguishes correct management, key to balancing medical and surgical needs, unlike true epidemiology or diagnostics.
Question 3 of 5
Columns of Bertin are
Correct Answer: C
Rationale: Columns of Bertin are cortical extensions between medullary pyramids structural dividers, not medullary. Pyramid apex is papillary urine exit. Medullary extensions are pyramids themselves wrong tissue. Conical areas are pyramids, not columns shape error. Cortical columns distinguish them, key to renal architecture, unlike medullary or conical misplacements.
Question 4 of 5
Which form of incontinence is usually treated medically initially?
Correct Answer: D
Rationale: Urge incontinence is treated medically first antimuscarinics or β3-agonists calm detrusor overactivity, addressing urgency. Stress incontinence (leak with pressure) often needs surgery pelvic support issue. Continuous suggests fistula surgical. Overflow (retention) may need catheterization obstruction-based. Urge's detrusor focus distinguishes it, key to initial medical management, unlike structural or retention types.
Question 5 of 5
Detrusor overactivity can be diagnosed during urodynamics
Correct Answer: A
Rationale: Detrusor overactivity (DO) is diagnosed by involuntary contractions during filling any size, reflecting bladder instability (e.g., urge incontinence). Amplitude threshold (e.g., >15 cm Hâ‚‚O) isn't required presence matters. Cough leakage is stress incontinence, not DO different mechanism. Voiding phase contractions are normal micturition, not overactivity. Filling-phase involuntariness distinguishes DO, key to its urodynamic definition, unlike size, stress, or voiding errors.
