Questions About The Urinary System Questions
Question 1 of 5
Which matched pair is INCORRECT:
Correct Answer: B
Rationale: Renin comes from juxtaglomerular cells (afferent arteriole), not efferent macula densa (DCT), fenestrated capillaries (glomerulus), and collecting tubules (rays) are correct. This distinguishes renin's source, key for RAAS, contrasting with vascular misplacement.
Question 2 of 5
The 'Cobble Stoned' or 'Beaded Necklace' appearance seen in plain radiograph of KUB is see in
Correct Answer: A
Rationale: Emphysematous cystitis shows a 'cobble stoned' or 'beaded necklace' X-ray appearance gas bubbles in bladder wall from infection (e.g., E. coli). Papillary necrosis lacks gas sloughed papillae. Pelvic lipomatosis shows fat, not gas radiolucent. Malacoplakia has plaques, not gas pattern chronic inflammation. Gas-driven cobble stoning distinguishes emphysematous cystitis, key to its radiographic diagnosis, unlike necrosis, fat, or plaque conditions.
Question 3 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 4 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 5 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.
