Urology Practice Questions

Q: All are true about the conditions shown in the figure except?

Painless intermittent hematuria. ***Painless intermittent hematuria*** - While hematuria **can occur** with vesical calculus, the **classic teaching** emphasizes that **painless hematuria should raise suspicion for bladder malignancy** rather than benign calculus. - In bladder stones, hematuria is typically **associated with other symptoms** such as dysuria, frequency, suprapubic pain, and urgency, making it part of a **symptomatic complex** rather than an isolated painless finding. - The **key distinguishing feature** is that isolated, painless intermittent hematuria without other urinary symptoms is **more characteristic of bladder cancer** than vesical calculus. - Therefore, while hematuria occurs with bladder stones, **"painless intermittent hematuria" as an isolated finding** is NOT the typical presentation pattern. *Vesical calculus* - The image shows a large **radio-opaque shadow** in the bladder region, consistent with a **vesical calculus** (bladder stone). - Bladder stones result from urinary stasis, infection, bladder outlet obstruction (BPH), or foreign bodies. - Symptoms include dysuria, frequency, urgency, suprapubic pain, and hematuria. *Holmium laser* - **Holmium:YAG laser lithotripsy** is an effective endoscopic treatment for bladder stones. - The laser fragments stones into small pieces that can be irrigated out or extracted. - It has advantages of being minimally invasive with excellent stone-free rates. *Litholapaxy* - **Litholapaxy** is the standard endoscopic procedure for bladder stone removal. - Involves mechanical fragmentation using a **lithotrite** followed by evacuation of fragments. - Performed through a cystoscope under vision, making it safe and effective for most bladder stones.

Q: The following instrument is used for:

Bladder wash when urinary catheter gets blocked. ***Bladder wash when urinary catheter gets blocked*** - The image shows a **rubber bulb syringe**, also known as an **irrigation syringe** or **bulb syringe**. This instrument is commonly used to create suction or to instill fluid, making it ideal for procedures like bladder irrigation. - In cases where a **urinary catheter becomes blocked** by mucus plugs, clots, or debris, a bladder wash (irrigation) with sterile saline can help clear the obstruction and restore drainage. This syringe would enable a nurse or physician to manually flush the catheter. *Dilate urethral stricture* - **Urethral stricture dilation** requires specialized instruments such as **urethral dilators** or **balloon catheters**, which are designed to gradually widen the narrowed part of the urethra. - The flexible, bulb-type syringe shown is not rigid enough nor designed with the specific shape or size increments required for urethral dilation. *Relieve bladder outlet obstruction temporarily* - Temporary relief of **bladder outlet obstruction** (BOO) typically involves inserting a **urinary catheter** (e.g., Foley catheter) to drain urine directly from the bladder. - While a syringe can connect to a catheter for drainage, the syringe itself is not the primary instrument for relieving the obstruction; the catheter is. This syringe is for irrigation purposes, not direct catheterization to relieve obstruction. *Perform uroflowmetry* - **Uroflowmetry** is a diagnostic test that measures the **rate of urine flow** during voiding. It requires a specialized device called a **uroflowmeter**, which is typically a funnel or toilet-like apparatus connected to a sensor that measures flow rate and volume. - The pictured syringe plays no role in measuring the natural flow of urine during micturition.

Q: Which is incorrect about the swelling shown below?

Possible to get above swelling. ***Possible to get above swelling*** - The image shows a **transilluminating scrotal swelling**, characteristic of a **hydrocele**. - A hydrocele originates from within the scrotum (testicular origin), so you **CANNOT get above the swelling** during physical examination. - The statement "Possible to get above swelling" is **INCORRECT** for a hydrocele - this is the key distinguishing feature. - In contrast, an **inguinoscrotal hernia** descends from the inguinal canal, so you **CAN get above it** and feel the neck of the hernia. - Since the question asks "which is incorrect," this option is the **correct answer**. *Fluctuation positive* - Hydroceles contain clear fluid, making them **fluctuant** on palpation. - A wave-like impulse can be transmitted through the fluid from one side to the other. - This statement is **correct** about hydroceles. *Fluid aspiration* - **Aspiration of fluid** from a hydrocele is possible for diagnostic or therapeutic purposes. - The aspirated fluid is typically straw-colored and clear if uncomplicated. - This statement is **correct** about hydroceles. *Transillumination positive* - The image clearly shows **positive transillumination**, where light passes through the swelling. - This indicates the swelling is **fluid-filled** and not solid. - This is a hallmark sign of hydrocele, distinguishing it from hernia or tumor. - This statement is **correct** about hydroceles.

Q: Identify the instrument shown in the image:

Asepto syringe. ***Asepto syringe*** - The image displays a **red rubber bulb** attached to a glass or plastic barrel ending in a nozzle, which is characteristic of an **Asepto syringe**. - Asepto syringes are commonly used for **irrigation** of wounds or surgical sites, and for various procedures where precise suction or fluid delivery is needed without a needle. *Trocar for tapping hydrocele* - A **trocar** is a pointed medical instrument with a sharp tip, typically used with a cannula to introduce instruments or drain fluids from a body cavity. - Trocars for hydrocele tapping would differ significantly in appearance, featuring a pointed tip and often a stylet, which are absent here. *Czerny retractor* - A **Czerny retractor** is a surgical instrument with two blades, used primarily to hold back tissue during surgery to provide a clear view of the surgical field. - The instrument shown here is focused on fluid suction/delivery, not on tissue retraction. *Malecot catheter* - A **Malecot catheter** is a type of self-retaining catheter, typically made from soft, flexible material, with a distinctive mushroom-shaped tip that helps anchor it within a viscus. - This image clearly depicts a syringe-like device with a bulb, not a flexible catheter with a four-winged tip.

Q: What does the following image show?

Stenting for pyeloplasty. ***Stenting for pyeloplasty*** - The image shows a **double J stent** placed in the ureter, which is commonly used to ensure **urine drainage** and **prevent stricture** after reconstructive surgeries like pyeloplasty. - The stent extends from the renal pelvis (upper coiled end) down into the bladder (lower coiled end), typical positioning for urinary tract procedures. *Stenting for bile duct obstruction* - Stents for **bile duct obstruction** are placed within the biliary system, which is anatomically distinct from the urinary tract shown. - These stents would be visible in the upper abdomen, associated with the liver and pancreas, not spanning the kidney and bladder as seen here. *Stenting for ESWL* - **Extracorporeal Shock Wave Lithotripsy (ESWL)** is a procedure to break up kidney stones; stents may be placed before or after to facilitate stone fragment passage or relieve obstruction. - While a stent might be placed after ESWL, the image itself shows the placement and course of the stent, which is a common intervention following reconstructive procedures such as pyeloplasty. *Stenting for PCNL* - **Percutaneous Nephrolithotomy (PCNL)** is a surgical procedure to remove large kidney stones directly from the kidney. - After PCNL, a **nephrostomy tube** or a **ureteral stent** may be placed, but the primary indication shown in the image (a long-term indwelling stent from kidney to bladder) is most consistent with facilitating healing and drainage after reconstruction such as pyeloplasty.

Q: During evaluation of a child with recurrent UTI, VCUG is performed and the following finding is observed. What is the diagnosis?

Posterior urethral valves. ***Posterior urethral valves*** - The image shows a **dilated and elongated posterior urethra** which is characteristic of posterior urethral valves (PUV). Also evident is **trabeculation of the bladder wall** and significant **bilateral vesicoureteral reflux (VUR)**, with a dilated and tortuous left ureter. - PUV frequently cause **recurrent UTIs** in male infants and children due to urinary obstruction and stasis, leading to bladder and upper tract damage. *Ureterocele* - A ureterocele would appear as a **cystic dilation of the distal ureter** into the bladder, typically visualized as a lucent defect within the opaque bladder on VCUG. The image does not show this specific finding. - While it can cause obstruction and VUR, the obstruction pattern observed in the image (especially the posterior urethra) is not consistent with a ureterocele. *Ectopic ureter* - An ectopic ureter involves the ureter inserting into an abnormal location, such as the vagina, urethra, or seminal vesicle, often bypassing the bladder. This would lead to a more direct drainage outside the bladder or into another structure without the gross changes seen in the posterior urethra. - While an ectopic ureter can lead to reflux or obstruction affecting the kidney, the primary obstruction in the **posterior urethra** with characteristic valve morphology is absent with an ectopic ureter. *Hydronephrosis* - **Hydronephrosis** refers to the swelling of a kidney due to a backup of urine, often caused by an obstruction or VUR. While hydronephrosis is a *consequence* of conditions like PUV, it is not the *diagnosis* explaining the direct VCUG findings in the bladder and urethra. - The VCUG directly visualizes the obstruction in the posterior urethra and associated reflux/bladder changes, which are the primary diagnostic features, rather than just the renal swelling.

Q: The radiographic image shows a stent in the urinary tract. This type of stenting is most commonly performed following which procedure?

Pyeloplasty. ***Pyeloplasty*** - **Double J stents** are routinely placed in virtually all pyeloplasties (Anderson-Hynes dismembered pyeloplasty for **UPJO - Ureteropelvic Junction Obstruction**) to stent the anastomosis and ensure proper **urine drainage**. - The stent prevents **PUJ stricture** formation and supports healing of the surgical anastomosis, making it a standard postoperative measure. *ESWL* - **Extracorporeal Shock Wave Lithotripsy (ESWL)** rarely requires routine stenting unless there is **large stone burden** or risk of steinstrasse (stone fragment obstruction). - Stenting after ESWL is **selective**, not universally performed, unlike the routine nature implied by the question. *PCNL* - **Percutaneous Nephrolithotomy (PCNL)** primarily uses **nephrostomy tube** for drainage rather than double J stents as the first-line drainage method. - DJ stent placement after PCNL is **optional/selective**, not the most common stenting indication compared to pyeloplasty. *Ureteroscopy (URS)* - **Ureteroscopy** may require stenting in cases of **ureteral injury**, significant edema, or large stone burden, but it's placed **selectively**. - Unlike pyeloplasty, stenting after URS is **not universal** and depends on specific procedural factors and complications.

Q: Which of the following uroflowmetry recording indicates BPH?

Curve 3. ***Curve 3*** - Curve 3 shows a **low, flattened peak flow rate** (around 5 mL/sec) and a **prolonged voiding time**, which is characteristic of significant bladder outlet obstruction due to BPH. - The **sustained low flow** indicates constant effort to overcome resistance, a common finding in BPH. *Curve 1* - Curve 1 depicts a **high peak flow rate** (around 30 mL/sec) and a **short voiding time**, representing a normal and efficient urinary flow pattern. - This pattern is inconsistent with BPH, which is characterized by obstructed flow. *Curve 2* - Curve 2 indicates a **moderately reduced peak flow rate** (around 15 mL/sec) and a somewhat prolonged voiding time compared to normal. - While reflecting some degree of obstruction or weaker detrusor function, it is less severe than curve 3 and may represent early BPH or other conditions. *Curve 4* - Curve 4 shows an **intermittent or staccato flow pattern**, which typically indicates detrusor-sphincter dyssynergia or abdominal straining during voiding. - This pattern is not characteristic of BPH, which typically shows a continuous low flow rather than intermittent flow.

Q: A 70-year-old man underwent the procedure shown below. 3rd day he develops seizures. What is the diagnosis?

Water intoxication. ***Water intoxication*** - The image depicts a **transurethral resection of the prostate (TURP)** using a resectoscope. During TURP, large volumes of **hypotonic irrigation fluid** are used. - If excess fluid is absorbed into the systemic circulation, it can lead to **dilutional hyponatremia** and subsequent **cerebral edema**, causing neurological symptoms like **seizures** post-operatively. *Anesthetic over-dosage* - Anesthetic overdose would typically manifest during or immediately after the procedure with respiratory and cardiovascular depression, not delayed seizures on the third day. - The patient's presentation of seizures several days post-operatively does not align with acute anesthetic toxicity. *Mismatched blood transfusion* - A mismatched blood transfusion would present with acute symptoms like fever, chills, hemoglobinuria, and hypotension, usually *during* or immediately after the transfusion, not delayed neurological symptoms. - Blood transfusions are not routinely part of a TURP procedure unless significant bleeding occurs. *Malignant hyperthermia* - Malignant hyperthermia is a rare, life-threatening **hypermetabolic state** triggered by certain general anesthetics, characterized by rapid onset of high fever, muscle rigidity, and tachycardia. - It occurs *during* or very soon after anesthesia and would not typically present as seizures on the third post-operative day.
