Urology Practice Questions

Q: The Grayhack shunt is established between which of the following?

Corpora cavernosa and saphenous vein. ***Corpora cavernosa and saphenous vein*** - The **Grayhack shunt** is a proximal **cavernosal-venous shunt** that connects the corpus cavernosum to the **great saphenous vein**. - This procedure surgically manages **refractory priapism** by diverting blood away from the trapped penile cavernosal spaces into the systemic venous circulation. - It is performed when distal and proximal corporeal shunts have failed. *Corpora cavernosa and dorsal vein* - This describes the **Barry shunt**, which connects the corpus cavernosum to the **deep dorsal vein**. - The Al-Ghorab shunt (sometimes confused) is actually a **distal corporo-glanular shunt** involving open excision of glans tissue — not a dorsal vein shunt. *Corpora cavernosa and glans* - This describes **distal cavernosal-glanular shunts** such as the **Winter shunt** (percutaneous needle) or **Ebbehoj shunt** (scalpel incision), which create a communication between the corpus cavernosum and the glans penis. - These are **first-line** surgical options for priapism but are distinct from the proximal Grayhack shunt. *Corpora cavernosa and corpora spongiosa* - This describes the **Quackels shunt**, a **proximal cavernosal-spongiosal shunt** connecting the corpora cavernosa to the corpus spongiosum. - Also used for refractory priapism, but anatomically and surgically distinct from the Grayhack (cavernosal-venous) shunt.

Q: A 65 year old male presents with CA prostate. The tumour is limited to the capsule and it is palpable on PR examination. The patient is diagnosed as stage T2a. What is the most appropriate treatment option?

Surgical removal of the prostate (Radical prostatectomy). ***Surgical removal of the prostate (Radical prostatectomy)*** - **Radical prostatectomy** is the **definitive treatment of choice** for **localized prostate cancer (T2a)** in patients with **good life expectancy (>10 years)**. - For a **65-year-old patient** with tumor confined to the prostate, **surgical removal offers excellent disease control** and potential cure. - This is the **preferred option** when the patient is **medically fit for surgery** and has adequate life expectancy. *External beam radiation therapy* - **External beam radiation therapy (EBRT)** is also an effective treatment for **localized T2a prostate cancer** with comparable long-term survival outcomes. - However, **radical prostatectomy is generally preferred** in younger, healthier patients as it: - Provides definitive pathological staging - Allows for immediate assessment of surgical margins - Preserves radiation as a salvage option if needed - EBRT is better suited for patients who are **not surgical candidates** due to comorbidities or patient preference. *Active surveillance* - **Active surveillance** is appropriate for **very low-risk prostate cancer** (T1c, PSA <10, Gleason ≤6). - For **T2a disease** (palpable tumor), the risk of progression is significant, making active surveillance **not the most appropriate first-line option**. - Would be considered only in patients with limited life expectancy or significant comorbidities. *Androgen deprivation therapy (ADT)* - **ADT** is used for **advanced, locally advanced, or metastatic prostate cancer** to reduce testosterone and slow tumor growth. - It is **not curative** and not appropriate as **monotherapy for localized T2a disease**. - May be used as adjuvant therapy with radiation in higher-risk cases, but not as primary treatment alone.

Q: A 54 year old woman is diagnosed as having carcinoma of the renal pelvis of size less than 4 cm without any metastasis. The best treatment option is

Radical Nephroureterectomy. ***Radical Nephroureterectomy*** - Carcinoma of the **renal pelvis** is a type of upper tract urothelial carcinoma (UTUC). Because of the multifocal nature and higher risk of recurrence of UTUC, **radical nephroureterectomy** (which includes removal of the kidney, ureter, and bladder cuff) is the standard treatment, even for smaller tumors. - Unlike renal cell carcinoma, partial nephrectomy is generally not recommended for renal pelvis carcinomas due to the risk of leaving behind residual disease in the ureter or bladder cuff. *Partial nephrectomy* - This is generally reserved for small, localized **renal cell carcinomas**, especially when kidney function preservation is a concern (e.g., solitary kidney, bilateral tumors). - For **renal pelvis carcinomas**, partial nephrectomy is associated with a higher risk of local recurrence because of the potential for tumor spread within the ureter and multifocal disease. *Chemotherapy and immunotherapy* - **Chemotherapy** (often cisplatin-based) might be used as neoadjuvant or adjuvant therapy for locally advanced or high-risk UTUC, or for metastatic disease. It is not the primary curative treatment for localized disease. - **Immunotherapy** is typically reserved for advanced or metastatic urothelial carcinoma that has progressed after chemotherapy. *Palliative Radiotherapy* - **Radiotherapy** has a limited role in the primary curative treatment of renal pelvis carcinoma. - It is mainly used in a **palliative setting** for symptom control (e.g., bone metastases, local pain) in advanced or metastatic disease, not for localized, resectable tumors.

Q: A 45-year-old male is diagnosed with carcinoma of the penis. Which lymph nodes should the surgeon primarily consider for potential metastasis?

Inguinal lymph nodes (located in the groin region). ***Inguinal lymph nodes (located in the groin region)*** - The lymphatic drainage of the penis primarily bypasses the internal nodal basins and drains directly to the **superficial and deep inguinal lymph nodes**. - Metastasis to these nodes is the **most common initial spread** in penile carcinoma, making them the primary targets for surgical evaluation and dissection. *Para-aortic lymph nodes (located near the aorta)* - These nodes are typically involved in more advanced or widespread metastatic disease, following initial spread to the pelvic nodes. - They are not considered the primary draining lymph nodes for penile carcinoma. *External iliac lymph nodes (located along the external iliac vessels)* - While part of the pelvic lymph node chain, the external iliac nodes are usually involved after metastasis to the inguinal nodes, or in cases of direct invasion of the pelvic floor. - They are not the first echelon of lymphatic drainage for the penis. *Internal iliac lymph nodes (located along the internal iliac vessels)* - These nodes are involved in lymphatic drainage from organs like the bladder, prostate, and rectum. - The lymphatic drainage of the penis primarily bypasses these nodes for initial metastasis.

Q: A high-riding prostate is indicative of which injury?

Membranous Urethral Injury. ***Membranous Urethral Injury*** - A **high-riding prostate** is a classic sign of **membranous urethral injury**, often resulting from **pelvic fractures**. - The disruption of the **urethra** above the perineal membrane causes the prostate to be displaced superiorly and appear "high." *Extraperitoneal Bladder rupture* - This typically occurs with **pelvic fractures** and involves urine leaking into the **retropubic space**. - While associated with pelvic trauma, it does not directly cause a high-riding prostate; the bladder itself may be ruptured, but the relative position of the prostate is not significantly altered. *Intraperitoneal Bladder Rupture* - This type of rupture usually results from a direct blow to a **full bladder** and involves urine extravasating into the **peritoneal cavity**. - It does not cause a high-riding prostate, as the injury is to the dome of the bladder, not the structures supporting the prostate. *Bulbar Urethral Injury* - A **bulbar urethral injury** usually results from a **straddle injury** and is located in the anterior urethra. - This type of injury does not affect the anatomical position of the prostate, which is posterior and superior to the bulbar urethra.

Q: A young male presents with a testicular mass on the right side. The AFP is elevated while the HCG is normal. The most appropriate next step is

Orchidectomy. ***Radical Inguinal Orchidectomy*** - In a patient who already presents with a **testicular mass** and **elevated AFP** (suggesting non-seminomatous germ cell tumor), the most appropriate next step is **radical inguinal orchidectomy**. - This procedure is both **diagnostic and therapeutic**, providing tissue for histopathological confirmation while removing the primary tumor. - The standard management sequence is: clinical examination → scrotal USG → tumor markers → **orchidectomy** → staging imaging → further treatment based on histology and stage. - Since the mass is already identified and tumor markers are done, proceeding directly to orchidectomy is appropriate. *USG* - Scrotal **ultrasound** is typically the **first imaging modality** when a testicular mass is suspected or palpated. - However, in this scenario, the mass is already clinically identified and tumor markers (AFP) have been measured, suggesting that initial workup including USG has likely been completed. - USG would have been the appropriate answer if the question asked for the "first investigation" before tumor markers were done. *Biopsy* - Direct **biopsy** of a testicular mass is **contraindicated** due to the high risk of tumor cell spillage along the needle tract, which can alter staging and worsen prognosis. - Testicular cancer is diagnosed via **radical inguinal orchidectomy**, not biopsy. *Wait and Watch* - A **wait and watch** approach is inappropriate and dangerous in the presence of a **testicular mass with elevated AFP**, which strongly suggests malignancy (non-seminomatous germ cell tumor). - Delayed treatment can lead to disease progression, metastasis, and poorer outcomes.

Q: Most common anomaly of upper urogenital tract is -

Uretero pelvic junction stenosis. ***Uretero pelvic junction stenosis*** - **Ureteropelvic junction (UPJ) obstruction** is the most common cause of **antenatally detected hydronephrosis**, making it the most frequent anomaly of the upper urogenital tract. - It results from an intrinsic or extrinsic narrowing at the junction of the **renal pelvis** and the **ureter**, impeding urine flow. *Ectopic urethral opening* - This anomaly involves the **urethral opening** being in an abnormal location, such as **hypospadias** or **epispadias** in males, or into the vagina in females. - While relatively common, it is an anomaly of the **lower urogenital tract**, specifically the urethra, not the upper tract. *Ureterocele* - A ureterocele is a **cystic dilation** of the distal part of the ureter as it enters the bladder. - While it can be associated with varying degrees of **upper tract obstruction**, it is not as common as UPJ stenosis. *Ectopic ureter* - An ectopic ureter involves a ureter that drains into an abnormal location other than the **trigone of the bladder**. - This condition is less common than UPJ stenosis and is often associated with a **duplex collecting system**.

Q: Young male with history of trauma having left sided testis swollen and erythematous. Other side normal. What is the diagnosis?

Hematoma. ***Hematoma*** - A history of **trauma** leading to a **swollen and erythematous testis** is highly indicative of a testicular hematoma. Trauma can cause bleeding within the scrotal sac, leading to the observed symptoms. - A hematoma is a localized collection of **blood outside of blood vessels**, which in this case, results from the injury to the testis or surrounding structures. *Torsion* - Testicular torsion typically presents with **sudden, severe pain** and swelling, and can be associated with absent **cremasteric reflex**. While swelling is present, the clear history of trauma points away from spontaneous torsion. - Torsion is an **emergency** caused by the twisting of the spermatic cord, which **cuts off blood supply** to the testis, and usually lacks a direct antecedent trauma. *Carcinoma* - Testicular carcinoma usually presents as a **painless, firm mass** within the testis. Pain can occur if there is hemorrhage within the tumor or rapid growth. - While it can cause swelling, the acute onset and direct association with trauma make carcinoma less likely, as it is a **slowly progressive** condition. *Hernia* - An inguinal hernia typically presents as a **groin bulge** that can extend into the scrotum, and usually reduces with manipulation or lying down. It is often associated with a cough or strain. - While a hernia can cause scrotal swelling, the primary presentation is usually a reducible mass, and the direct link to trauma with associated erythema is not typical for a simple hernia.

Q: In testicular torsion, within what time frame should surgery be performed to save the viability of the testis?

6 hr. ***6 hr*** - Testicular viability is highest when **detorsion** occurs within **6 hours** of symptom onset. - Delay beyond this timeframe significantly increases the risk of **testicular ischemia** and necrosis. *12 hr* - While some viability may remain, the probability of **testicular salvage** decreases substantially after 6 hours. - Testicular function, including **sperm production**, is often compromised even if the testis is saved. *24 hr* - Beyond 12-24 hours, the likelihood of **testicular viability** is very low, and **orchiectomy** (testicle removal) is often necessary. - Prolonged ischemia leads to irreversible **tissue damage** and infarction. *1 week* - After one week, the testis is almost certainly non-viable due to **prolonged ischemia** and necrosis. - This delay would invariably result in the need for **orchiectomy**.

Q: All are true about carcinoma penis except which of the following?

Spreads by blood borne metastasis. ***Spreads by blood borne metastasis*** - Carcinoma penis typically spreads initially via the **lymphatic system** to inguinal lymph nodes. - **Hematogenous spread** is a late event and generally rare, with the most common sites being the lung, liver, and bone. *Leads to erosion of artery* - Local advancement of penile carcinoma can lead to **erosion of penile arteries**, which can cause significant morbidity including bleeding and functional compromise. - This local tissue destruction is a characteristic feature of advanced, uncontrolled penile cancer. *Slowly progressive* - Carcinoma penis is generally a **slowly progressive** malignancy, allowing for early detection and intervention if patients seek medical attention promptly. - The slow growth rate contributes to the fact that many patients present with localized or regionally advanced disease before distant metastases occur. *Most common type is squamous cell carcinoma* - Approximately 95% of penile cancers are **squamous cell carcinomas (SCCs)**, arising from the epithelial cells of the glans or foreskin. - Other rare types include melanoma, basal cell carcinoma, and sarcomas, but SCC vastly predominates.
