Urology Practice Questions

Q: A 70-year-old male presents with difficulty urinating. Examination reveals a mass in the pelvis. Which structure is most likely to be enlarged?

Prostate. ***Prostate*** - In a 70-year-old male presenting with **difficulty urinating** and a pelvic mass, an enlarged prostate is the most likely cause. This is indicative of **benign prostatic hyperplasia (BPH)**, a common condition in older men. - The enlarged prostate can compress the **urethra**, leading to symptoms like **urinary hesitancy, weak stream, nocturia, and incomplete bladder emptying** [1]. *Bladder* - While bladder distension can occur secondary to **urinary outflow obstruction**, the bladder itself is not typically the structure that *enlarges* as the primary cause of the obstruction in this scenario. - A palpable bladder mass would usually indicate a **distended bladder** due to urinary retention rather than a primary bladder enlargement causing the obstruction. *Seminal vesicle* - Enlargement of the seminal vesicles is generally **not associated with urinary obstruction** and is usually asymptomatic unless there is inflammation or a rare malignancy. - The seminal vesicles are located posterior to the bladder and do not typically exert pressure on the urethra in a way that causes significant urinary symptoms or a palpable pelvic mass in the context of voiding difficulty. *Urethra* - The urethra is a **tube-like structure**; it does not "enlarge" to form a mass in the pelvis. - Instead, the urethra can be **compressed or strictured**, leading to obstruction, but its anatomical structure prevents it from forming a palpable mass.

Q: A 45-year-old man presents with gross hematuria and a palpable abdominal mass. A CT scan reveals a renal mass with metastasis to the lungs. What is the most appropriate treatment strategy for this patient?

Total nephrectomy and immunotherapy. **Total nephrectomy and immunotherapy** - The presence of a **palpable abdominal mass**, gross hematuria, and **pulmonary metastases** indicates advanced renal cell carcinoma, making **total nephrectomy** essential for tumor burden reduction. - **Immunotherapy** (e.g., PD-1 inhibitors) is the first-line systemic treatment for metastatic renal cell carcinoma, offering improved survival outcomes compared to traditional chemotherapy. *Partial nephrectomy and radiation therapy* - **Partial nephrectomy** is typically reserved for smaller, localized renal masses to preserve renal function, which is not indicated in the presence of **metastatic disease**. - **Radiation therapy** has a limited role in the primary treatment of renal cell carcinoma and is mostly used for **palliative care** for bone or brain metastases, not as a primary treatment for the renal tumor. *Transplantation with immunosuppression* - **Kidney transplantation** is only considered in patients with end-stage renal disease (ESRD) and no malignancy, or in highly selected cases of small, localized renal tumors in the explanted kidney, not for **metastatic cancer**. - **Immunosuppression** in the context of transplantation would actually be detrimental in a patient with metastatic cancer as it could accelerate tumor growth. *Chemotherapy only* - **Renal cell carcinoma** is notoriously **chemotherapy-resistant**, making it ineffective as a primary treatment for metastatic disease. - Targeted therapies or **immunotherapy** have largely replaced chemotherapy in the management of advanced renal cell carcinoma due to superior efficacy.

Q: A 70-year-old woman presents with recurrent urinary tract infections and a palpable pelvic mass. An ultrasound shows a large, irregular mass on the anterior wall of the bladder. What is the most likely diagnosis?

Bladder cancer. ***Bladder cancer*** - The combination of **recurrent UTIs**, a **palpable pelvic mass**, and an **irregular mass on the anterior bladder wall** on ultrasound is highly suggestive of bladder cancer, which can present with these non-specific symptoms. - Bladder cancer is more common in older individuals and can lead to symptoms like recurrent infections due to compromised bladder integrity or obstruction. *Uterine fibroids* - While uterine fibroids can present as a **pelvic mass**, they typically arise from the **uterus**, not the bladder wall. - They are less likely to cause recurrent UTIs unless they are very large and compress the bladder or ureters. *Cystocele* - A cystocele is a **prolapse of the bladder** into the vagina, manifesting as a bulge or pressure, not typically an irregular mass *on* the bladder wall seen on ultrasound. - While it can cause recurrent UTIs due to incomplete bladder emptying, the description of an "irregular mass" points away from this condition. *Bladder diverticulum* - A bladder diverticulum is an **outpouching of the bladder wall**, which can be congenital or acquired. - While it can be associated with recurrent UTIs due to urinary stasis, it is generally a **smooth-walled pouch** and not typically described as a large, "irregular mass" on the anterior bladder wall, which suggests a solid or infiltrative lesion.

Q: A 45-year-old man presents with a painless, enlarged scrotum. The transillumination test reveals a cystic mass. What is the most likely diagnosis?

Hydrocele. ***Hydrocele*** - A **hydrocele** is a collection of fluid in the **tunica vaginalis**, which typically presents as a **painless, enlarged scrotum** that transilluminates. - The **transillumination test** is positive because the fluid within the hydrocele allows light to pass through. *Inguinal hernia* - An **inguinal hernia** usually presents as a scrotal swelling that does not transilluminate and may be **reducible**. - It involves the protrusion of abdominal contents, not fluid, into the scrotum. *Varicocele* - A **varicocele** is an enlargement of the **pampiniform plexus veins** within the scrotum, often described as feeling like a "bag of worms." - It does not transilluminate and is more commonly associated with a dull ache or heaviness, and can be associated with infertility. *Testicular torsion* - **Testicular torsion** is an acute, painful condition caused by the twisting of the **spermatic cord**, leading to inadequate blood flow to the testis. - It is characterized by sudden, severe pain and tenderness, and is a medical emergency that does not transilluminate.

Q: A 30-year-old male presents with an acute onset of severe scrotal pain. The scrotum is swollen and tender. What is the most likely diagnosis?

Testicular torsion. ***Testicular torsion*** - The sudden onset of **severe scrotal pain** in a young male, accompanied by **swelling and tenderness**, is highly suggestive of testicular torsion. - Testicular torsion is a **surgical emergency** requiring prompt intervention to preserve testicular viability. *Epididymitis* - While epididymitis also causes scrotal pain and swelling, its onset is typically more **gradual** and is often associated with **dysuria or fever**. - Physical examination may reveal a **positive Prehn's sign** (pain relief with elevation of the testicle), which is usually absent in torsion. *Hydrocele* - A hydrocele is a collection of fluid around the testis, usually presenting as a **painless scrotal swelling** that can be transilluminated. - It does not typically cause acute, severe pain unless it becomes infected or acutely enlarges due to trauma. *Inguinal hernia* - An inguinal hernia can cause scrotal swelling, but the pain is often described as a **dull ache** or a feeling of heaviness, especially with straining, rather than acute severe pain. - A hernia typically presents as a **reducible mass** that may extend into the scrotum.

Q: A young male presents with a painless testicular mass suspicious for germ cell tumor. Which of the following tumor markers would be most useful for initial evaluation?

Alpha-Fetoprotein (AFP). ***Alpha-Fetoprotein (AFP)*** - **AFP** is a key tumor marker in **germ cell tumors**, particularly in **non-seminomatous** testicular tumors such as **yolk sac tumors** [1]. - It is often elevated in patients with a **painless testicular mass**, aiding in the diagnosis and management of these tumors [1]. *CA-125* - **CA-125** is primarily used as a tumor marker for **ovarian cancer** rather than testicular tumors, making it less relevant here. - It is often elevated in **pelvic inflammatory disease** and **endometriosis**, not specific to male genital tract tumors. *Carcinoembryonic Antigen (CEA)* - **CEA** is mostly associated with **colorectal** and **lung cancers**, and is not typically involved in testicular tumor diagnosis [1]. - While it may have some role in gastrointestinal malignancies, it does not serve as a useful marker for **testicular masses** [2]. *Prostate-Specific Antigen (PSA)* - **PSA** is specific for **prostate disorders**, including cancer, but does not provide relevant information for testicular tumors [1] [2]. - Its elevation is indicative of conditions related to the **prostate gland**, which is not involved in the context of a testicular mass [2].

Q: Radical nephrectomy involves resection of the following structures, which one is not typically resected?

Proximal para-aortic lymph nodes. ***Proximal para-aortic lymph nodes*** - **Proximal para-aortic lymph nodes** are NOT routinely resected during radical nephrectomy unless there is evidence of gross nodal involvement on imaging or intraoperatively. - The extent of lymph node dissection is tailored to individual disease burden; hilar and regional nodes are addressed, but distant nodal groups like proximal para-aortic nodes are only resected when clearly involved. - Extended lymphadenectomy to proximal para-aortic regions is not part of standard radical nephrectomy. *Gerota's fascia* - **Gerota's fascia** (perirenal fascia) is **always resected** in radical nephrectomy as it encases the kidney and perirenal fat. - En bloc resection of Gerota's fascia with the kidney ensures complete tumor removal, clear margins, and prevents tumor spillage. - This is a defining component of "radical" versus "simple" nephrectomy. *Ipsilateral adrenal gland (in classical approach)* - In **classical radical nephrectomy** (Campbell-Walsh traditional description), the ipsilateral adrenal gland was routinely removed due to proximity and concern for tumor extension. - **Modern practice** has shifted to adrenal-sparing nephrectomy as the standard, with adrenalectomy reserved for upper pole tumors with direct invasion, bulky tumors, or imaging abnormalities. - For this question's context of "classical radical nephrectomy," the adrenal gland **IS typically resected** in the traditional approach. *Surrounding hilar lymph nodes* - **Hilar lymph nodes** are routinely resected during radical nephrectomy for staging and regional disease control. - These nodes are the first-line lymphatic drainage sites and their removal is integral to proper oncologic surgery. - Hilar lymphadenectomy is a standard component of radical nephrectomy.

Q: 40 years old male complains of loin pain since 1 month. Patient's complaint of pain has severely increased over last 2 hours and pain now radiates from loin and to groin and anterior thigh and patient is writhing in bed for comfort. What is the most probable etiology?

Ureteric calculus. ***Ureteric calculus*** - The sudden onset of **severe, colicky loin pain radiating to the groin and anterior thigh**, causing the patient to writhe in bed, is highly characteristic of **ureteric colic** due to a calculus [1]. - This pain pattern is due to the obstruction and spasm of the ureter as it tries to pass the stone, with referred pain along the genitofemoral and ilioinguinal nerves [1]. *Bladder calculus* - A bladder calculus typically causes **suprapubic pain**, **dysuria**, **frequency**, and sometimes **hematuria**, but usually not severe, radiating loin-to-groin pain. - Pain from a bladder stone is often worse during micturition and can be relieved by changing position. *Vesicoureteric reflux* - **Vesicoureteric reflux (VUR)** is a backward flow of urine from the bladder to the ureters and kidneys, most commonly causing **recurrent UTIs** and potentially **renal scarring**. - It typically does not present with the acute, severe, radiating pain described, which is classic for an acute obstruction [2]. *Hydronephrosis* - **Hydronephrosis** refers to the swelling of the kidney due to a buildup of urine, often caused by obstruction, but it is a *consequence* rather than the primary etiology in this acute presentation [2]. - While a ureteric calculus can cause hydronephrosis, the term itself describes the *result* of the obstruction, not the acute event causing the severe pain [2].

Q: Normal urine flow rate in healthy adults in urodynamic study is -

20 ml/sec. ***20 ml/sec*** - A peak urinary flow rate of **20 mL/second** is considered normal in healthy adult males when voiding a volume of 200 mL or more. - In women, a maximum flow rate above **25 mL/second** is considered normal when voiding similar volumes. *10 ml/sec* - A maximum flow rate of less than **15 mL/second** is commonly considered to suggest significant bladder outlet obstruction in men. - This value is generally indicative of a potentially abnormal urinary flow, requiring further investigation. *25 ml/sec* - While **25 mL/second** or more is considered normal for women, for men, this rate is at the higher end of the normal range and not the average healthy adult flow rate. - This option is more typically associated with unimpeded flow in females, not the general population of healthy adults. *5 ml/sec* - A flow rate of **5 mL/second** is significantly below the normal range for healthy adults and would suggest a severe urinary obstruction or very poor detrusor function. - This value is usually seen in patients with significant bladder outlet obstruction or compromised bladder muscle function.
