Questions About The Urinary System Questions
Question 1 of 5
In Sarcoidosis, Hypercalciuria occurs as a result of
Correct Answer: A
Rationale: In sarcoidosis, hypercalciuria stems from absorptive hypercalciuria excess vitamin D from granulomas increases gut calcium absorption, spilling into urine. Renal hypercalciuria involves kidney leak, not primary in sarcoidosis absorption drives it. Low calcium intake reduces, not raises, urinary calcium opposite effect. Reduced oxalate excretion is unrelated oxalate binds calcium, not source here. Absorptive mechanism distinguishes sarcoidosis' systemic etiology, key to its stone risk, unlike renal, dietary, or oxalate factors.
Question 2 of 5
The electrocautery employed during TURBT may result in stimulation of which nerve
Correct Answer: A
Rationale: TURBT electrocautery can stimulate the obturator nerve runs near bladder lateral wall, causing thigh adduction (obturator kick). Sciatic nerve (leg) is distant unrelated. Genitofemoral (genital) and ilioinguinal (inguinal) innervate other areas bladder surgery spares them. Obturator's proximity distinguishes it, key to this surgical complication, unlike distant or regional nerves.
Question 3 of 5
In multipara MRI which one of the following statement is INCORRECT?
Correct Answer: D
Rationale: DCE MRI assesses vascularity (contrast uptake), not clear anatomic images T2 does anatomy incorrect. T1 detects hemorrhage (bright) true. T2 shows prostate zones (anatomic) accurate. DWI measures water diffusion (cancer detection) correct. DCE's functional focus distinguishes the error, key to multiparametric MRI's role, unlike true imaging modes.
Question 4 of 5
All of the following are the principles of urinary fistula repair except
Correct Answer: C
Rationale: Fistula repair principles include tension-free, watertight closure, and postoperative drainage ensure healing, prevent leaks. Excision of the tract isn't universal preservation viable in small/simple cases, not always required. Tension-free reduces recurrence, watertight seals urine, drainage avoids pressure. Non-mandatory excision distinguishes it, key to flexible repair strategies, unlike essential surgical tenets.
Question 5 of 5
The most common urodynamic findings in patients with Parkinson disease with lower urinary tract dysfunction is
Correct Answer: C
Rationale: Parkinson's LUT dysfunction commonly shows detrusor overactivity (DO) basal ganglia loss causes uninhibited contractions, urgency. Sphincter dyssynergia is spinal (e.g., MS) not Parkinson's. Bradykinesia affects voluntary sphincter less urodynamic. Impaired contractility is late DO predominates. Overactivity distinguishes it, key to Parkinson's bladder issues, unlike spinal or contractile findings.
