Urology Practice Questions

Q: Which of the following is not part of the classical triad of renal cell carcinoma?

Oliguria. ***Oliguria*** - **Oliguria** (decreased urine output) is not considered part of the classical triad for renal cell carcinoma. - It usually indicates significant **renal dysfunction** or **obstruction**, which might occur in advanced stages or with complications, but not always as an initial presenting symptom. *Loin Mass* - A **palpable abdominal or flank mass** is one of the key components of the classical triad, indicating a larger, more advanced tumor. - This symptom often suggests that the tumor has grown significantly to be detectable by physical exam or patient sensation. *Hematuria* - **Hematuria** (blood in the urine), often macroscopic and painless, is a common and important early symptom of renal cell carcinoma. - It results from the tumor invading the **collecting system** of the kidney, causing bleeding. *Loin Pain* - **Loin pain** (flank pain) is another component of the classical triad, often caused by tumor growth stretching the **renal capsule** or invading adjacent structures. - The pain can be dull, aching, or more severe if there is acute bleeding or obstruction.

Q: A couple complains of an inability to conceive despite staying together for 4 years and having unprotected intercourse, with all tests in the wife being normal. Semen analysis shows a volume of 0.8 mL, a sperm count of 0, and the absence of fructose. What is the next best step?

Local palpation of Vas. ***Local palpation of Vas*** - The findings of **azoospermia** (sperm count of 0), **low semen volume** (0.8 mL), and **absence of fructose** are highly suggestive of an **ejaculatory duct obstruction** or **congenital bilateral absence of the vas deferens (CBAVD)**, as seminal vesicles produce fructose and contribute to semen volume. - **Palpation of the vas deferens** is a simple, non-invasive initial step to assess for the presence or absence of the vas deferens, which would strongly indicate CBAVD and guide further management. *Testicular FNAC* - **Fine needle aspiration cytology (FNAC)** of the testis would demonstrate active **spermatogenesis** if the issue is a post-testicular obstruction, but it does not directly identify the site of obstruction or the absence of the vas deferens. - While it can differentiate between obstructive and non-obstructive azoospermia, it is typically performed after initial physical examination and imaging to locate the obstruction. *Ultrasound for obstruction* - An **ultrasound (transrectal)** can be used to visualize the ejaculatory ducts and seminal vesicles to identify an obstruction, but it is typically performed *after* physical examination, especially if there is suspicion of CBAVD following palpation. - If the vas deferens are already confirmed to be absent on palpation, the primary issue is likely CBAVD rather than solely an ejaculatory duct obstruction that could be visualized by ultrasound within the ejaculatory duct. *Karyotyping* - **Karyotyping** is useful in cases of **non-obstructive azoospermia** to detect chromosomal abnormalities (e.g., Klinefelter syndrome) or in cases of CBAVD to look for mutations in the CFTR gene related to cystic fibrosis. - However, given the specific semen analysis findings (low volume, absent fructose), a physical examination focusing on the vas deferens is a more immediate and targeted next step.

Q: Which of the following is the most serious complication of untreated urethral stricture?

Periurethral abscess. ***Periurethral abscess*** - An untreated urethral stricture can lead to urinary stasis and infection, which can then progress to a **periurethral abscess**. - A periurethral abscess is a serious localized collection of pus that can rupture internally or externally, causing severe pain, infection, and potentially necessitating complex surgical intervention. *Urethral diverticulum* - While urethral strictures can contribute to the formation of a **urethral diverticulum** due to increased pressure and obstruction, it is generally considered a less immediate and life-threatening complication compared to an abscess. - A diverticulum is an outpouching of the urethra, which can cause symptoms like dysuria, recurrent UTIs, and post-void dribbling, but does not typically pose the same acute infectious risk as an abscess. *Retention of urine* - **Urinary retention** is a common and significant symptom of a urethral stricture, as the narrowing blocks the flow of urine. - While uncomfortable and requiring intervention, acute urinary retention itself is usually manageable with catheterization and does not carry the same degree of tissue destruction and systemic infection risk as a periurethral abscess. *All of these* - While all listed options can be complications of an untreated urethral stricture, **periurethral abscess** represents the most serious due to its potential for severe infection, tissue destruction, and more complex management. - The question asks for the **most serious** complication, which points to the one with the highest morbidity and potential for systemic consequences.

Q: What is the most common type of bladder rupture?

Extraperitoneal bladder rupture. **Extraperitoneal bladder rupture** - This type of rupture is the most common kind, accounting for **80-85% of all bladder ruptures**. - It typically occurs due to high-energy blunt trauma to the lower abdomen or pelvis when the bladder is full, often associated with **pelvic fractures**. *Intraperitoneal bladder rupture* - This type is less common than extraperitoneal ruptures, representing about **15-20% of cases**. - It usually results from a direct blow to a **distended bladder** when the dome of the bladder, which is covered by peritoneum, ruptures. *Rupture at the trigone of the bladder* - Ruptures isolated to the **trigone** are rare and typically not a separate classification of bladder rupture type in terms of prevalence. - The trigone is a more robust area of the bladder, making rupture here less common without significant penetrating trauma or specific iatrogenic injury. *Both types occur with equal frequency* - This statement is incorrect as **extraperitoneal ruptures** are significantly more prevalent than intraperitoneal ruptures. - The mechanisms of injury and associated findings also differ between the two main types, distinguishing their frequency.

Q: What is the definitive treatment for established 'Thimble bladder' with structural damage?

Ileocystoplasty. ***Ileocystoplasty*** - **Ileocystoplasty** is a surgical procedure to enlarge the bladder using a segment of the ileum, providing definitive treatment for the severely contracted and scarred bladder seen in "Thimble bladder" with structural damage. - This procedure addresses the **reduced bladder capacity** and functional problems caused by irreversible fibrosis. *Anti-tubercular treatment* - While essential for treating active **urogenital tuberculosis**, it does not reverse the established **structural damage and fibrosis** that characterize "Thimble bladder." - It prevents further progression of the disease but cannot restore lost bladder capacity or elasticity once scarring is significant. *Anti-tubercular drugs plus corticosteroids* - Adding **corticosteroids** might reduce inflammation in active tuberculosis but will not repair the extensive and long-standing **fibrotic changes and structural damage** in a developed "Thimble bladder." - The primary aim of ATD is to eradicate the infection, and corticosteroids are usually reserved for specific inflammatory complications. *Corticosteroids* - **Corticosteroids** primarily exert anti-inflammatory and immunosuppressive effects, which are not beneficial for reversing fixed **fibrotic changes** in a bladder with established "Thimble bladder." - Their use would be inappropriate as a standalone treatment for irreversible structural damage, as they do not address the underlying mechanical issue of a contracted bladder.

Q: Organ which is commonly involved in retroperitoneal fibrosis is

Ureter. ***Ureter*** - Retroperitoneal fibrosis is characterized by the proliferation of **fibrous tissue in the retroperitoneum**, which commonly encases the ureters. - This encasement can lead to **ureteral obstruction**, causing hydronephrosis and potential renal impairment. *Colon* - While the colon is located in the retroperitoneum for some segments (ascending, descending), it is **less commonly entrapped** and obstructed by retroperitoneal fibrosis compared to the ureters. - **Bowel obstruction** is not a primary or common clinical manifestation of retroperitoneal fibrosis. *Duodenum* - The duodenum is primarily located in the **upper retroperitoneum** but is generally less affected by the fibrotic process characteristic of retroperitoneal fibrosis. - **Obstructive symptoms related to the duodenum** are rare in this condition. *Kidneys* - The kidneys are retroperitoneal organs, but the fibrosis typically involves the **perirenal fat and surrounding structures**, not the kidney parenchyma itself. - Renal dysfunction in retroperitoneal fibrosis is usually a **secondary complication of ureteral obstruction**, not direct renal involvement.

Q: Which of the following is least likely to occur after transurethral resection of the prostate?

Transient blindness. ***Transient blindness*** - Transient blindness (amaurosis) is the **rarest complication** among the options listed, though it has been reported in severe TURP syndrome. - Ocular complications occur due to **severe hyponatremia** and cerebral edema affecting the visual cortex or retinal edema, but this is an **uncommon manifestation** compared to other neurological symptoms. - Most cases of TURP syndrome present with more typical features before visual symptoms develop. *Hyponatremia* - **Hyponatremia** is the **hallmark and most common feature** of TURP syndrome, occurring in up to 10-15% of procedures. - Caused by systemic absorption of **hypotonic irrigation fluid** (glycine or sorbitol solutions) during prolonged resection. - This is the primary electrolyte disturbance that leads to all other manifestations of TURP syndrome. *Convulsion* - **Convulsions (seizures)** are a **common neurological manifestation** of TURP syndrome when hyponatremia is severe (Na+ <120 mEq/L). - Result from **cerebral edema** and increased intracranial pressure due to rapid osmotic fluid shifts. - Generalized tonic-clonic seizures are well-recognized complications requiring immediate treatment. *Congestive cardiac failure* - **CHF** commonly occurs due to rapid absorption of **large volumes of irrigation fluid** causing acute **volume overload**. - The increased intravascular volume can precipitate pulmonary edema and cardiac decompensation, especially in elderly patients with pre-existing cardiac disease. - This is a frequent complication requiring diuretic therapy and fluid restriction.

Q: Which of the following conditions is characterized by a fluid-filled cyst that transilluminates and contains sperm-rich fluid?

Spermatocele. ***Spermatocele*** - A spermatocele is a **benign, fluid-filled cyst** that usually arises from the head of the epididymis. - It classically **transilluminates** on examination and contains **sperm-rich fluid**, which distinguishes it from other scrotal masses. *Hydrocele* - A hydrocele is a collection of **serous fluid** within the tunica vaginalis surrounding the testis. - While it also **transilluminates**, its contents are typically clear or straw-colored serous fluid, not sperm-rich. *Lymphatic cyst* - A lymphatic cyst is a rare lesion resulting from abnormal development of the **lymphatic system**. - It typically contains **lymphatic fluid**, which is clear to milky, and would not contain sperm. *Parasitic cyst* - Parasitic cysts in the scrotal region are uncommon and are caused by infections such as **filariasis**. - These cysts do not typically transilluminate and would contain inflammatory or parasitic material, not sperm-rich fluid.

Q: A 20-year-old male presented to the emergency department with acute onset of pain in the right scrotum. On examination, the testes were swollen, and the transillumination test was negative. What could be the probable diagnosis based on the ultrasound of the scrotum?

Testicular torsion. ***Testicular torsion*** - The ultrasound image shows a significant **lack of blood flow** (absent or markedly decreased color flow signals) in the right testis compared to the left, which is characteristic of **testicular torsion**. - **Acute onset of pain**, swollen testis, and a **negative transillumination test** in a young male are clinical signs highly suggestive of testicular torsion, requiring urgent intervention. *Fournier's syndrome* - This is a severe form of **necrotizing fasciitis** of the perineum and genitals, typically presenting with crepitus, gangrene, and systemic symptoms, which are not described. - Ultrasound would show gas in the soft tissues and possibly fluid collections, not primarily compromised testicular blood flow within the testis itself. *Acute epididymitis* - Acute epididymitis would typically show **increased blood flow** (hyperemia) in the affected epididymis and potentially the testis on Doppler ultrasound. - While it causes acute scrotal pain and swelling, the key differentiator here is the **absent/decreased blood flow** on the ultrasound, which rules out epididymitis. *Hydrocele* - A hydrocele is a collection of **fluid around the testis**, which would appear as an anechoic (black) fluid collection on ultrasound. - A hydrocele typically would yield a **positive transillumination test** and does not usually cause acute, severe pain or lead to a significant change in testicular blood flow on Doppler like torsion does.

Q: Which of the following structures in the spermatic cord is typically preserved (not divided) during vasectomy surgery?

Testicular artery. ***Testicular artery*** - The goal of a vasectomy is to interrupt sperm transport, not the blood supply to the testis. The **testicular artery** is the most critical structure to preserve as it provides the primary blood supply to the testis. - Preserving the **testicular artery** ensures continued blood flow to the testis, preventing ischemia and maintaining both spermatogenesis (though sperm won't exit) and endocrine function (testosterone production). - Surgeons carefully isolate and preserve the testicular artery while dividing only the vas deferens. *Vas deferens* - The **vas deferens** is the target structure that is deliberately divided and ligated during vasectomy. - Cutting the **vas deferens** interrupts the pathway for sperm transport from the epididymis to the ejaculatory duct, achieving permanent contraception. - This is the only structure within the spermatic cord that is intentionally divided during the procedure. *Autonomic nerves* - While **autonomic nerves** (sympathetic postganglionic fibers) are present in the spermatic cord and innervate the vas deferens, they may be inadvertently damaged during the vasectomy procedure. - The primary function of these **autonomic nerves** related to the vas deferens is smooth muscle contraction for sperm transport, which becomes irrelevant once the vas deferens is divided. - These nerves are not actively preserved as their division doesn't significantly impact testicular function. *Testicular vein* - The **testicular vein** (pampiniform plexus) drains blood from the testis and is also typically preserved during vasectomy, along with the testicular artery. - However, the **testicular artery** is considered more critical as arterial blood supply is essential for tissue viability, whereas venous drainage has collateral pathways through cremasteric and deferential veins. - Both vessels are preserved, but the arterial supply takes priority in surgical technique.
