Prostate surgery basics US Medical PG Question 1: A 68-year-old man with hypertension comes to the physician because of fatigue and difficulty initiating urination. He wakes up several times a night to urinate. He does not take any medications. His blood pressure is 166/82 mm Hg. Digital rectal examination shows a firm, non-tender, and uniformly enlarged prostate. Which of the following is the most appropriate pharmacotherapy?
- A. Finasteride
- B. α-Methyldopa
- C. Phenoxybenzamine
- D. Terazosin (Correct Answer)
- E. Tamsulosin
Prostate surgery basics Explanation: ***Terazosin***
- **Terazosin** is an alpha-1 blocker that relaxes the smooth muscles in the prostate and bladder neck, improving urine flow and relieving symptoms of **benign prostatic hyperplasia (BPH)**.
- It also has the added benefit of lowering blood pressure, making it suitable for this patient with both **BPH** and **hypertension**.
*Finasteride*
- **Finasteride** is a 5-alpha reductase inhibitor that reduces prostate volume by inhibiting the conversion of testosterone to **dihydrotestosterone (DHT)**.
- While effective for **BPH**, it takes longer to show benefits (6-12 months) and does not address the patient's **hypertension**.
*α-Methyldopa*
- **α-Methyldopa** is a centrally acting alpha-2 adrenergic agonist used to treat **hypertension**, particularly in pregnancy.
- It does not have a direct effect on prostate smooth muscle and would not alleviate the patient's urinary symptoms.
*Phenoxybenzamine*
- **Phenoxybenzamine** is a non-selective, irreversible alpha-adrenergic blocker primarily used for **pheochromocytoma** to control blood pressure.
- Its non-selective nature and side effect profile make it less suitable for chronic management of **BPH** and **hypertension** compared to selective alpha-1 blockers.
*Tamsulosin*
- **Tamsulosin** is a selective alpha-1A adrenergic blocker that specifically targets the prostate, rapidly improving **BPH** symptoms with less effect on blood pressure.
- While it effectively treats **BPH**, unlike terazosin, it does not offer the additional advantage of lowering the patient's elevated blood pressure.
Prostate surgery basics US Medical PG Question 2: A 65-year-old man is brought to the emergency department by ambulance after falling during a hiking trip. He was hiking with friends when he fell off a 3 story ledge and was not able to be rescued until 6 hours after the accident. On arrival, he is found to have multiple lacerations as well as a pelvic fracture. His past medical history is significant for diabetes and benign prostatic hyperplasia, for which he takes metformin and prazosin respectively. Furthermore, he has a family history of autoimmune diseases. Selected lab results are shown below:
Serum:
Na+: 135 mEq/L
Creatinine: 1.5 mg/dL
Blood urea nitrogen: 37 mg/dL
Urine:
Na+: 13.5 mEq/L
Creatinine: 18 mg/dL
Osmolality: 580 mOsm/kg
Which of the following is the most likely cause of this patient's increased creatinine level?
- A. Autoimmune disease
- B. Compression of urethra by prostate
- C. Blood loss (Correct Answer)
- D. Diabetic nephropathy
- E. Rhabdomyolysis
Prostate surgery basics Explanation: ***Correct: Blood loss***
- The fall from a 3-story ledge and subsequent **pelvic fracture** indicate a high likelihood of significant **internal bleeding** and **hypovolemia**, leading to decreased renal perfusion and a pre-renal acute kidney injury (AKI) as evidenced by the elevated BUN/creatinine ratio (37/1.5 = 24.7), low urine sodium, and high urine osmolality.
- **Hypovolemia** from blood loss is a common cause of **pre-renal AKI**, characterized by the kidneys attempting to conserve fluid, resulting in concentrated urine with low sodium.
*Incorrect: Autoimmune disease*
- While a family history of autoimmune diseases exists, there is no direct evidence in the current presentation (e.g., specific markers, symptoms) to suggest an **autoimmune nephritis** as the acute cause of his renal dysfunction.
- Autoimmune causes of kidney injury typically present with proteinuria, hematuria, or other systemic inflammatory signs, which are not described.
*Incorrect: Compression of urethra by prostate*
- Although the patient has benign prostatic hyperplasia (BPH) and takes prazosin (an alpha-blocker to treat BPH), their current presentation of **pre-renal AKI** with concentrated urine does not fit typical **post-renal obstruction**.
- **Post-renal obstruction** from BPH would typically present with symptoms like difficulty urinating, elevated bladder volume, and often hydronephrosis, none of which are indicated here as the primary cause of acute renal failure.
*Incorrect: Diabetic nephropathy*
- The patient's history of diabetes makes **diabetic nephropathy** a potential cause of chronic kidney disease, but the **acute increase in creatinine** following a traumatic event strongly suggests an acute insult rather than a sudden exacerbation of chronic diabetic kidney disease.
- **Diabetic nephropathy** usually develops over years, presenting with proteinuria and a gradual decline in GFR, not an acute surge in creatinine following an injury, and it does not explain the pre-renal parameters seen in the urine.
*Incorrect: Rhabdomyolysis*
- While a severe fall could potentially cause **rhabdomyolysis** (muscle breakdown), the provided lab values do not include elevated **creatine kinase**, which is the hallmark of this condition.
- Although rhabdomyolysis can cause AKI, the **pre-renal parameters** (high BUN/Cr ratio, low urine Na, high urine osmolality) are more consistent with hypovolemia from blood loss rather than direct tubular injury from myoglobin.
Prostate surgery basics US Medical PG Question 3: A 40-year-old woman was admitted to the surgical service after an uncomplicated appendectomy. She underwent surgery yesterday and had an uneventful postoperative course. However, she now complains that she is unable to completely void. She also complains of pain in the suprapubic area. You examine her and confirm the tenderness and fullness in the suprapubic region. You ask the nurse to perform a bladder scan, which reveals 450cc. What is the next appropriate step in management?
- A. Catheterization (Correct Answer)
- B. Oral bethanechol chloride
- C. Neostigmine methylsulfate injection
- D. Intravenous furosemide
- E. Intravenous neostigmine methylsulfate
Prostate surgery basics Explanation: **Catheterization**
- The patient is presenting with **acute urinary retention**, confirmed by the inability to void, suprapubic pain, and a bladder scan showing 450cc, which exceeds the typical threshold for intervention (often 200-300cc).
- **Immediate catheterization** (usually Foley catheterization) is necessary to drain the bladder, relieve discomfort, and prevent complications like bladder distension injury or hydronephrosis.
*Oral bethanechol chloride*
- Bethanechol is a **cholinergic agonist** used to stimulate bladder contraction in cases of hypotonic bladder, but it is not appropriate for acute, complete urinary retention requiring immediate drainage.
- Its onset of action is too slow for the urgency of acute retention, and it would not resolve the immediate discomfort or risk of bladder damage.
*Neostigmine methylsulfate injection*
- Neostigmine is an **acetylcholinesterase inhibitor** that increases acetylcholine levels, potentially improving bladder contractility, but it is not typically the first-line treatment for acute postoperative urinary retention.
- Like bethanechol, it doesn't provide the rapid relief of bladder distension that catheterization does and is more often considered for chronic or neurogenic bladder dysfunction once acute retention is managed.
*Intravenous furosemide*
- Furosemide is a **loop diuretic** that increases urine production, which would exacerbate the problem in a patient with acute urinary retention.
- Increasing urine output without the ability to void would worsen bladder distension and patient discomfort, making it a contraindicated intervention.
*Intravenous neostigmine methylsulfate*
- While neostigmine can be given intravenously, its use in acute postoperative urinary retention is **not a primary treatment**.
- Its effect is slower than direct bladder drainage, and the immediate priority is to decompress the bladder to relieve symptoms and prevent complications.

- A. Urethral stricture
- B. Prostate cancer
- C. Neurogenic bladder
- D. Acute prostatitis
- E. Benign prostatic hyperplasia (Correct Answer)
Prostate surgery basics Explanation: ***Benign prostatic hyperplasia***
- The patient's symptoms of **frequent urination**, **nocturia**, **weak urinary stream**, and a **slightly enlarged, smooth, nontender prostate** on rectal exam are classic for BPH.
- Recurrent **cystitis** can be a complication of BPH due to incomplete bladder emptying.
*Urethral stricture*
- While a urethral stricture can cause a **weak urinary stream** and incomplete emptying, it would typically present with more significant difficulty voiding, possibly **pain** during urination, or a history of instrumentation/trauma.
- The rectal exam finding of an **enlarged prostate** points away from a primary stricture.
*Prostate cancer*
- Although prostate cancer can cause similar urinary symptoms, an enlarged prostate due to cancer is often described as **nodular, firm, or asymmetric** on rectal exam, not smooth.
- The absence of **hematuria** or significant pain also makes cancer less likely as the primary driver of these symptoms.
*Neurogenic bladder*
- A neurogenic bladder would involve neurological deficits affecting bladder control, such as spinal cord injury, stroke, or severe neuropathy, which are not described in this patient beyond an **essential tremor** unlikely to cause these specific lower urinary tract symptoms.
- The patient has no other neurological symptoms like **focal weakness** or sensory loss.
*Acute prostatitis*
- Acute prostatitis typically presents with **fever, chills, perineal pain, dysuria**, and a **tender, swollen prostate** on examination, none of which are present in this patient.
- The symptoms here are **chronic** (1 year history) rather than acute.
Prostate surgery basics US Medical PG Question 5: A 59-year-old man comes to the physician because of a 3-month history of frequent urination. He has to urinate every 1–2 hours during the day and wakes up at least 2–3 times at night to urinate. He also reports that over the last 2 months, he has difficulty initiating micturition and the urinary stream is weak, with prolonged terminal dribbling. His pulse is 72/min, and blood pressure is 158/105 mm Hg. Rectal exam shows a smooth, symmetrically enlarged prostate without any tenderness or irregularities. Prostate-specific antigen is within the reference range and urinalysis shows no abnormalities. A postvoid ultrasound shows a residual bladder volume of 110 mL. Which of the following is the most appropriate next step in management?
- A. Transurethral resection of the prostate
- B. Terazosin therapy (Correct Answer)
- C. Bladder catheterization
- D. Finasteride therapy
- E. Cystoscopy
Prostate surgery basics Explanation: ***Terazosin therapy***
- Terazosin is an **alpha-1 adrenergic antagonist** that blocks receptors in the prostate and bladder neck, causing relaxation of the smooth muscle and improving urinary flow. This is a first-line medical treatment for symptomatic **benign prostatic hyperplasia (BPH)**.
- The patient presents with **obstructive and irritative lower urinary tract symptoms (LUTS)**, a symmetrically enlarged prostate, and a postvoid residual volume that indicates bladder outlet obstruction, all consistent with BPH.
- Alpha-blockers provide **rapid symptom relief** (within days to weeks) and may also help with the patient's **elevated blood pressure** (158/105 mm Hg).
*Transurethral resection of the prostate*
- **Transurethral resection of the prostate (TURP)** is a surgical intervention reserved for patients with severe BPH symptoms refractory to medical therapy or those with complications like recurrent urinary retention or renal dysfunction.
- Given that the patient has not yet tried medical therapy, and his symptoms are not immediately life-threatening, surgery is not the most appropriate first step.
*Bladder catheterization*
- **Bladder catheterization** is indicated for acute urinary retention or in cases of severe bladder obstruction leading to renal impairment.
- While the patient has significant LUTS and a postvoid residual volume, he is not in acute urinary retention, so immediate catheterization is not necessary as a long-term management strategy.
*Finasteride therapy*
- **Finasteride** is a **5-alpha reductase inhibitor** that reduces prostate size by inhibiting the conversion of testosterone to dihydrotestosterone. It is more effective in patients with larger prostate volumes and takes several months to show its full effect.
- Though a valid treatment for BPH, alpha-blockers like terazosin provide faster symptomatic relief by addressing dynamic obstruction and are generally preferred as initial therapy, often in combination with 5-alpha reductase inhibitors for larger prostates.
*Cystoscopy*
- **Cystoscopy** is an invasive procedure used to visualize the bladder and urethra directly. It is typically reserved for cases where there is suspicion of other pathologies like bladder stones, strictures, or bladder cancer, or for preoperative planning.
- The patient's symptoms and examination findings are consistent with BPH, and his PSA is normal, so primary cystoscopy is not indicated as the next step in management.
Prostate surgery basics US Medical PG Question 6: A 67-year-old man presents to his primary care physician complaining of frequent urination overnight. He states that for several years he has had trouble maintaining his urine stream along with the need for frequent urination, but the nighttime urination has only recently started. The patient also states that he has had 2 urinary tract infections in the last year, which he had never had previously. On exam, his temperature is 98.8°F (37.1°C), blood pressure is 124/68 mmHg, pulse is 58/min, and respirations are 13/min. On digital rectal exam, the prostate is enlarged but feels symmetric and smooth. Which of the following is a possible consequence of this condition?
- A. Increased serum creatinine (Correct Answer)
- B. Malignant transformation
- C. Increased serum AFP
- D. Increased serum hCG
- E. Increased serum ALP
Prostate surgery basics Explanation: ***Increased serum creatinine***
- Chronic **urinary retention** due to benign prostatic hyperplasia (BPH) can lead to **hydronephrosis** and **renal parenchymal damage**, impairing kidney function and increasing serum creatinine.
- The patient's symptoms of difficulty maintaining urine stream, frequent urination, and recurrent UTIs suggest BPH, which can progress to urinary obstruction and subsequent kidney dysfunction.
*Malignant transformation*
- **Benign prostatic hyperplasia (BPH)** is a non-malignant condition and does not directly undergo **malignant transformation** into prostate cancer.
- While both BPH and prostate cancer can coexist, BPH itself is not considered a premalignant lesion.
*Increased serum AFP*
- **Alpha-fetoprotein (AFP)** is a tumor marker primarily associated with **hepatocellular carcinoma** and **germ cell tumors** (e.g., testicular cancer).
- It is not associated with benign prostatic hyperplasia (BPH) or its complications.
*Increased serum hCG*
- **Human chorionic gonadotropin (hCG)** is a tumor marker most notably elevated in **choriocarcinoma** and some **germ cell tumors**.
- It has no association with benign prostatic hyperplasia (BPH) or urinary obstruction.
*Increased serum ALP*
- **Alkaline phosphatase (ALP)** can be elevated in conditions affecting the **liver** (e.g., cholestasis) or **bones** (e.g., Paget's disease, osteoblastic metastases).
- While significantly elevated ALP can indicate prostate cancer with **bone metastases**, it is not a direct consequence of uncomplicated benign prostatic hyperplasia (BPH).
Prostate surgery basics US Medical PG Question 7: Three hours after undergoing open proctocolectomy for ulcerative colitis, a 42-year-old male complains of abdominal pain. The pain is localized to the periumbilical and hypogastric regions. A total of 20 mL of urine has drained from his urinary catheter since the end of the procedure. Temperature is 37.2°C (98.9°F), pulse is 92/min, respirations are 12/min, and blood pressure is 110/72 mm Hg. Pulse oximetry on room air shows an oxygen saturation of 99%. Physical examination shows a 20 cm vertical midline incision and an ileostomy in the right lower quadrant. There is no fluid drainage from the surgical wounds. The urinary catheter flushes easily and is without obstruction. Cardiopulmonary examination shows no abnormalities. Serum studies show a blood urea nitrogen of 30 mg/dL and a creatinine of 1.3 mg/dL. Which of the following is the most appropriate next step in management?
- A. Administer tamsulosin
- B. Administer intravenous furosemide
- C. Obtain an abdominal CT
- D. Start ciprofloxacin
- E. Administer intravenous fluids (Correct Answer)
Prostate surgery basics Explanation: ***Administer intravenous fluids***
- The patient's **oliguria** (20 mL urine over 3 hours, ~7 mL/hour) post-surgery, elevated **BUN (30 mg/dL)**, and **creatinine (1.3 mg/dL)** with a **BUN:Cr ratio >20:1** suggest **prerenal acute kidney injury** due to **hypovolemia**.
- Post-operative fluid losses from **third-spacing**, blood loss, and insensible losses commonly cause hypovolemia after major abdominal surgery.
- **Intravenous fluids** are the most appropriate initial step to restore intravascular volume and improve renal perfusion.
*Administer tamsulosin*
- **Tamsulosin** is an alpha-blocker used to relax smooth muscle in the prostate and bladder neck, primarily for **urinary retention** due to benign prostatic hyperplasia.
- This patient's oliguria is due to **prerenal azotemia** from hypovolemia, not prostatic obstruction, and the catheter flushes easily without obstruction.
*Administer intravenous furosemide*
- **Furosemide** is a loop diuretic that increases urine output, but administering it in the context of **prerenal acute kidney injury** can worsen hypovolemia and further compromise renal function.
- Diuretics are generally contraindicated in oliguria due to hypovolemia and should only be considered after volume resuscitation.
*Obtain an abdominal CT*
- While an abdominal CT can diagnose surgical complications, there are no immediate signs of a surgical emergency like **anastomotic leak** or **bowel obstruction**.
- Addressing the likely **hypovolemia** is more urgent and should precede further imaging in this scenario.
*Start ciprofloxacin*
- The patient does not show signs of infection, such as fever or localized signs of bacterial peritonitis, making **antibiotics** like ciprofloxacin inappropriate as the initial management step.
- The elevated BUN and creatinine are more indicative of volume depletion than infection.
Prostate surgery basics US Medical PG Question 8: A 65-year-old African American man presents for follow-up examination with a 6-month history of urinary hesitancy, weak stream, and terminal dribbling, which is refractory to a combination therapy of finasteride and tamsulosin. The patient’s past medical history is otherwise unremarkable. His father and brother were diagnosed with prostate cancer at the age of 55 years. His vital signs are within normal limits. The patient has a normal anal sphincter tone and a bulbocavernosus muscle reflex. Digital rectal exam (DRE) reveals a prostate size equivalent to 2 finger pads with a hard nodule and without fluctuance or tenderness. Serum prostate-specific antigen (PSA) level is 5 ng/mL. Which of the following investigations is most likely to establish a definitive diagnosis?
- A. Magnetic resonance imaging (MRI)
- B. 4Kscore test
- C. Prostate Health Index (PHI)
- D. Image-guided needle biopsy (Correct Answer)
- E. PSA in 3 months
Prostate surgery basics Explanation: ***Image-guided needle biopsy***
- A definitive diagnosis of **prostate cancer** requires histological confirmation, which is achieved through a **biopsy**.
- The patient's presentation with a **hard nodule** on DRE, elevated PSA, and a strong family history of prostate cancer, despite treatment for BPH, strongly indicates the need for a biopsy.
*Magnetic resonance imaging (MRI)*
- While MRI can help in **staging prostate cancer** and guiding biopsies, it does not provide a definitive diagnosis on its own.
- An MRI may identify suspicious lesions but **cannot confirm malignancy** without tissue sampling.
*4Kscore test*
- The 4Kscore test estimates the **risk of high-grade prostate cancer** but does not provide a definitive diagnosis.
- It uses a panel of four prostate-specific kallikrein proteins, along with patient age, DRE status, and prior biopsy results, to calculate a risk score.
*Prostate Health Index (PHI)*
- The PHI is a blood test that combines total PSA, free PSA, and [-2]proPSA to assess the **probability of prostate cancer**.
- It helps in deciding whether a biopsy is needed, but like the 4Kscore, it is not a diagnostic tool in itself.
*PSA in 3 months*
- Re-checking PSA in 3 months would **delay definitive diagnosis** and treatment for a potentially aggressive cancer, especially given the palpable nodule and family history.
- The current PSA of 5 ng/mL, although not extremely high, combined with the suspicious DRE finding, warrants more immediate action.
Prostate surgery basics US Medical PG Question 9: An 8-year-old boy and his 26-year-old babysitter are brought into the emergency department with severe injuries caused by a motor vehicle accident. The child is wheeled to the pediatric intensive care unit with a severe injury to his right arm, as well as other external and internal injuries. He is hemorrhaging and found to be hemodynamically unstable. He subsequently requires transfusion and surgery, and he is currently unconscious. The pediatric trauma surgeon evaluates the child’s arm and realizes it will need to be amputated at the elbow. Which of the following is the most appropriate course of action to take with regards to the amputation?
- A. Obtain an emergency court order from a judge to obtain consent to amputate the child’s arm
- B. Find the child’s parents to obtain consent to amputate the child’s arm
- C. Amputate the child’s arm at the elbow joint (Correct Answer)
- D. Wait for the child’s babysitter to recover from her injuries to obtain her consent to amputate the child’s arm
- E. Wait for the child to gain consciousness to obtain his consent to amputate his arm
Prostate surgery basics Explanation: ***Amputate the child’s arm at the elbow joint***
- In an emergency situation where a child's life is at risk and a procedure is immediately necessary to save their life or prevent significant harm, **implied consent** allows for medical intervention without explicit parental consent. The child's **hemodynamic instability** and **severe hemorrhage** indicate an immediate threat to life.
- The decision to amputate to save the child's life is a **medically necessary emergency intervention**. Waiting for consent would cause a dangerous delay.
*Obtain an emergency court order from a judge to obtain consent to amputate the child’s arm*
- While court orders can be used in cases of parental refusal or unavailability for non-emergency procedures, the **urgent nature** of this life-threatening situation precludes waiting for a court order.
- The delay in obtaining a court order could significantly worsen the child's prognosis or lead to death.
*Find the child’s parents to obtain consent to amputate the child’s arm*
- Although parental consent is generally required for minors, the child's **critical condition** and **hemodynamic instability** mean delaying life-saving treatment to locate parents would be medically irresponsible.
- The principle of **beneficence** (acting in the best interest of the patient) and avoiding harm takes precedence in this emergency.
*Wait for the child’s babysitter to recover from her injuries to obtain her consent to amputate the child’s arm*
- A babysitter is generally not legally authorized to provide consent for major medical procedures for a child, especially an amputation.
- Even if the babysitter had some form of temporary custody, her own injury makes her an unreliable source of consent, and the delay would be critical.
*Wait for the child to gain consciousness to obtain his consent to amputate his arm*
- An 8-year-old child is generally not considered mature enough to provide **informed consent** for such a major medical decision.
- The child is **unconscious and hemodynamically unstable**, making it impossible to obtain consent and dangerously delaying a life-saving procedure.
Prostate surgery basics US Medical PG Question 10: A 28-year-old woman comes to the physician with a history of bright red blood in her stools for 3 days. She has defecated once per day. She does not have fever, pain on defecation, or abdominal pain. She was treated for a urinary tract infection with levofloxacin around 3 months ago. Menses occur at regular intervals of 28–30 days and lasts 3–4 days. Her father died of colon cancer 4 years ago. Her only medication is an iron supplement. She is 162 cm (5 ft 4 in) tall and weighs 101.2 kg (223 lbs); BMI is 38.3 kg/m2. Her temperature is 36.5°C (97.7°F), pulse is 89/min, and blood pressure is 130/80 mm Hg. Rectal examination shows anal skin tags. Anoscopy shows multiple enlarged bluish veins above the dentate line at 7 and 11 o'clock positions. When asked to exhale through a closed nostril a mass prolapses but spontaneously reduces when breathing normally. Which of the following is the most appropriate next step in management?
- A. Infrared coagulation
- B. Propranolol therapy
- C. Topical diltiazem
- D. Hemorrhoidectomy
- E. Docusate therapy (Correct Answer)
Prostate surgery basics Explanation: ***Docusate therapy***
- The patient presents with symptoms and signs consistent with **grade II internal hemorrhoids** (prolapses with straining but spontaneously reduces) and a history of constipation (implied by iron supplementation and obesity).
- **Conservative management with stool softeners** like docusate is the first-line treatment for grade II internal hemorrhoids, promoting easier bowel movements and reducing straining, which exacerbates hemorrhoids.
- Other conservative measures include increased dietary fiber and adequate hydration.
*Infrared coagulation*
- This is a **procedural treatment** sometimes used for grade I and II internal hemorrhoids that are **refractory to conservative management**.
- It is not the most appropriate initial step. Given the patient's presentation, **conservative management should be attempted first** before considering procedural interventions.
*Propranolol therapy*
- **Propranolol** is a beta-blocker used to manage **portal hypertension** and prevent variceal bleeding in patients with cirrhosis.
- There is **no indication of portal hypertension** or liver disease in this patient (normal vital signs, no stigmata of chronic liver disease).
- This medication is not used in the management of hemorrhoids.
*Topical diltiazem*
- **Topical diltiazem** is a calcium channel blocker used to treat **anal fissures** by relaxing the internal anal sphincter and improving blood flow to promote healing.
- The patient's symptoms (bright red blood, **no pain on defecation**) are not consistent with an anal fissure, which typically presents with severe pain during and after bowel movements.
*Hemorrhoidectomy*
- **Hemorrhoidectomy** is a surgical procedure typically reserved for **severe (grade III or IV)** internal hemorrhoids or those unresponsive to less invasive treatments.
- The patient's hemorrhoids are grade II, which are likely to respond to conservative management, making surgery an overly aggressive initial approach.
