Urology Practice Questions

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: What is the most common site of penile carcinoma?

Glans. ***Glans*** - The **glans penis** is the most frequent site of origin for penile carcinoma due to its exposure and susceptibility to chronic irritation and inflammation. - Approximately **50-70%** of penile cancers originate on the glans. *Prepuce* - The **prepuce** (foreskin) is the second most common site, often affected in uncircumcised males, but less frequently than the glans itself. - Carcinomas here often develop at the **mucocutaneous junction** of the prepuce. *Shaft* - The **penile shaft** is a much less common site for penile carcinoma, accounting for a smaller percentage of cases. - Cancers on the shaft tend to be **more aggressive** and may present with different clinical features. *Coronal sulcus* - The **coronal sulcus** is the groove between the glans and the shaft. While it's a common site for lesions, it is still less common than the glans itself for the primary origin of carcinoma. - Lesions here can often spread to the glans or prepuce, making the distinction difficult without a clear point of origin.

Q: A 40-year-old male presents with translucent scrotal swelling in which it is possible to get above the swelling on examination. What is the most probable diagnosis?

Hydrocele. ***Hydrocele*** - A **hydrocele** is characterized by a translucent scrotal swelling because it contains **serous fluid**, allowing light to pass through. - The ability to **get above the swelling** on examination indicates that it is confined to the scrotum and not extending into the inguinal canal, differentiating it from an indirect inguinal hernia. *Indirect inguinal hernia* - An **indirect inguinal hernia** is a protrusion of abdominal contents through the deep inguinal ring into the scrotum, meaning it would **not be possible to get above the swelling**. - It would typically be **non-translucent** as it contains bowel or omentum, not serous fluid. *Varicocele* - A **varicocele** is a collection of dilated veins in the pampiniform plexus, often described as a **"bag of worms"** on palpation, and is typically not translucent. - While located in the scrotum, it is usually distinguishable by its **palpable vascular nature** and often changes with Valsalva maneuver. *Sebaceous cyst* - A **sebaceous cyst** is a benign growth filled with keratinous material, originating from a blocked sebaceous gland. - It would be a **firm, non-translucent lump** and not a generalized scrotal swelling that allows light transmission.

Q: What is the most appropriate treatment for a patient with symptomatic bladder stones?

Transurethral litholapaxy. ***Transurethral litholapaxy*** - This procedure involves inserting a **cystoscope** through the urethra into the bladder to visualize and then fragment the stone using various energy sources (e.g., laser, pneumatic, ultrasound). - The fragmented pieces are then irrigated and removed, offering a **minimally invasive** and highly effective treatment for most bladder stones. *Percutaneous suprapubic litholapaxy* - This method is typically reserved for very **large or complex bladder stones** that are difficult to manage transurethrally. - It involves accessing the bladder directly through a **suprapubic incision**, which is more invasive than the transurethral approach. *Vesicotomy and stone retrieval* - A **vesicotomy** (open surgical incision into the bladder) is a more invasive procedure, usually considered when other less invasive methods have failed or are not feasible. - This approach carries higher risks, including **longer recovery times** and potential for greater complications compared to endoscopic options. *Intravenous antibiotics* - **Antibiotics** are used to treat or prevent urinary tract infections that may be associated with bladder stones, but they do not remove or dissolve the stones themselves. - While infection may be a concurrent issue, antibiotics alone **do not address the physical obstruction** or symptomatic cause of bladder stones.

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.

Q: What is the main hazard of ectopic testis -

Risk of carcinoma development. ***Risk of carcinoma development*** - Ectopic testis, like undescended testis (cryptorchidism), carries an **increased risk of germ cell tumors**, particularly **seminoma**. - An **ectopic testis** is one that has descended but deviated from the normal path and is located in an abnormal position (superficial inguinal pouch, perineum, femoral triangle, etc.). - While the malignancy risk in ectopic testis may be **slightly lower than true cryptorchidism**, it remains the **most significant long-term hazard**. - The increased risk is attributed to **abnormal testicular development** and **dysgenesis**, leading to potential malignant transformation. - Risk is estimated at **4-10 times higher** than normally descended testes. *Increased risk of impotence* - Ectopic testes can affect **fertility** due to impaired spermatogenesis from abnormal positioning and higher temperatures. - However, they do **not directly cause impotence** (erectile dysfunction). - Impotence relates to inability to achieve or maintain erection, which is a vascular, neurological, or psychological issue, not affected by testicular position. *Risk of hernia development* - An **inguinal hernia** can be associated with undescended testis if the processus vaginalis remains patent. - An ectopic testis, having deviated outside the normal path of descent, does **not typically predispose to hernia** formation in the same manner. - This is not the primary concern with ectopic testis. *Liable to injury* - An ectopic testis located in superficial positions (superficial inguinal pouch, perineum) is **more vulnerable to trauma** than a normally descended scrotal testis. - While trauma risk is a legitimate concern, it is **secondary** to the long-term risk of **malignancy**. - The risk of cancer development far outweighs the risk of traumatic injury in clinical significance.

Q: Earliest and often the only presentation of TB kidney is

Blood in urine. ***Blood in urine*** - **Hematuria** (blood in urine) is a common initial presentation of renal TB, often microscopic and sometimes macroscopic, appearing early due to inflammation and ulceration of the urinary tract. - The presence of **blood in urine** without significant pain or other classic infection signs can confuse the diagnosis, making it an "early" and *misleading* symptom without further investigation. *Sterile pyuria* - While **sterile pyuria** (pus cells in urine without bacterial growth on routine cultures) is highly suggestive of **TB kidney**, it tends to appear later in the disease progression as more significant renal damage and inflammation occur. - Early stages might not show prominent pyuria, and **hematuria** often precedes it as the initial symptom of tissue damage. *Colicky abdominal pain* - **Colicky abdominal pain** is more commonly associated with obstruction, such as from stone passage or severe hydronephrosis, which are typically later complications of TB kidney, not early presentations. - Early renal TB typically involves the parenchyma and calyces, not usually leading to significant obstruction that would cause colicky pain. *Kidney stones* - **Kidney stones** (renal calculi) are a potential long-term complication of renal TB due to metabolic changes, inflammation, and cellular debris, but they are not an *early* or *initial* symptom [1]. - The formation of stones usually indicates more advanced disease or chronic inflammation within the urinary tract [1].

Q: An elderly male patient presented with a sudden onset of scrotal pain and discharge as shown in the image. What is the likely diagnosis?

Fournier’s gangrene. ***Fournier's gangrene*** - The sudden onset of scrotal pain with discharge in an elderly male, combined with **tissue necrosis** and extensive scrotal skin changes, is characteristic of **Fournier's gangrene** (necrotizing fasciitis of the genitalia). - Elderly males are at higher risk due to **diabetes**, **immunocompromise**, and **urogenital infections**, making this a rapidly progressive and potentially life-threatening condition requiring urgent surgical debridement. *Acute epididymo-orchitis* - While epididymo-orchitis can cause scrotal pain and discharge, it typically does **not cause tissue necrosis** or the extensive scrotal skin changes described. - It presents as **localized inflammation** of the epididymis/testis without the widespread necrotizing changes seen in this case. *Torsion of testis* - Testicular torsion typically presents with **abrupt, severe scrotal pain** and swelling, but usually **without discharge** or the extensive scrotal skin changes seen here. - It constitutes a **surgical emergency** due to compromised blood supply to the testis, but doesn't involve necrotizing infection. *Scrotal carcinoma* - Scrotal carcinoma usually presents as a **painless mass or ulceration** that grows over time, rather than a sudden onset of severe pain and discharge. - It represents a **chronic process** and doesn't typically cause the acute necrotizing inflammatory changes observed in this case.

Q: Treatment of Renal cell carcinoma of less than 4 cm will be?

Partial nephrectomy. ***Partial nephrectomy*** - For **renal cell carcinoma (RCC) less than 4 cm** (T1a tumors), **partial nephrectomy** is the preferred treatment. This approach aims to preserve as much healthy renal tissue as possible, reducing the risk of chronic kidney disease, especially in patients with normal contralateral kidneys. - Studies have shown that partial nephrectomy offers comparable **oncologic outcomes** to radical nephrectomy for small tumors while providing better overall kidney function. *Radical nephrectomy* - While effective for larger tumors or those invading surrounding structures, **radical nephrectomy** involves removing the entire kidney, which may lead to a higher risk of **chronic kidney disease** compared to partial nephrectomy for small tumors. - This option is generally reserved for **larger tumors** (T1b or greater), more complex cases, or when partial nephrectomy is not feasible due to tumor location or patient comorbidities. *Radical nephrectomy + postoperative radiotherapy* - **Radiotherapy** is generally not effective in treating renal cell carcinoma (RCC) due to the **radioresistant nature** of the tumor cells. It is rarely used in the primary treatment of RCC. - The combination of radical nephrectomy and postoperative radiotherapy would expose the patient to unnecessary treatment with significant side effects without clear survival benefits for localized disease. *Radical nephrectomy + chemotherapy* - **Chemotherapy** has historically shown **limited efficacy** in the treatment of renal cell carcinoma, particularly for localized disease. It is primarily used in advanced, metastatic RCC, and newer targeted therapies and immunotherapies are often preferred. - For small, localized tumors, surgery alone is curative, and adding chemotherapy to radical nephrectomy would introduce **unnecessary toxicity** without improving outcomes.
