Questions About The Urinary System Questions
Question 1 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 2 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 3 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.
Question 4 of 5
A 67 years old man presented with lower urinary tract symptoms for last 10 months. On evaluation he was diagnosed as a case of carcinoma prostate with serum PSA 8 ng/mL and Gleason score of 3+4=7. PSMA/PET-CT scan was suggestive of uptake in left lobe of prostate and left internal iliac lymph node. As per latest national comprehensive cancer network guidelines, he belongs to which stage of prostate cancer?
Correct Answer: D
Rationale: Stage IVA prostate cancer (NCCN) includes regional lymph node spread (N1) here, left internal iliac node on PSMA-PET, with PSA <20 and Gleason 7 (intermediate). Stage IIA is T1/T2, N0 node-negative. IIIA is T1/T2, high PSA (>20), N0 PSA too low. IIIB is T3/T4, N0 local only. N1 distinguishes IVA, key to metastatic staging, unlike localized or PSA-driven stages.
Question 5 of 5
A 60 years old male with large (8 cm × 7.5 cm) right renal cell carcinoma requires occasional assistance but able to care for most of one's own needs. The Karnofsky performance Score of this patient is
Correct Answer: C
Rationale: Karnofsky score of 60 fits needs occasional help but manages most needs (e.g., 8 cm RCC, functional). 40 is bedridden too low. 50 requires frequent care overstated. 70 is near-normal underestimates impact. 60 distinguishes it, key to performance status in cancer, unlike severe or mild extremes.
