1. The most ominous sign or symptom of urinary system disease is :
A. Urinary frequency.
B. Pyuria.
C. Pneumaturia.
D. Dysuria.
E. Hematuria.

Answer E :
DISCUSSION:
While urinary frequency (voiding more than three to five times daily) or dysuria (painful voiding) may be asign of malignant disease, they are more commonly associated with nonmalignant inflammatory disease, neurologic disease,or calculous disease of the urinary tract.
Pyuria (pus in the urine) is most commonly associated with infection and not malignancy.
Pneumaturia (air or gas in the urine) indicates a fistula between bowel and the urinary tract or infection by fermination in diabetic urine
Hematuria (blood in the urine) is most worrisome. While this may be produced by infection or by calculous disease, it is most commonly associated with malignant disease in the absence of associated signs or symptoms such as pyuria, frequency, and dysuria.
Thus, of the ones mentioned, hematuria is the most ominous single sign or symptom.

2. A patient with acute urinary tract infection (UTI) usually presents with :
A. Chills and fever.
B. Flank pain.
C. Nausea and vomiting.
D.
5fiveTo 10 white blood cells per high-power field (hpf) in the uncentrifuged urine specimen.
E. Painful urination.

Answer E :
EDISCUSSION:
Cystitis or infection of the bladder is the most common UTI.
Lower UTI, or cystitis, is an infection in the bladder.
Painful urination and frequency are the most common presenting complaints.
Hematuria may occur, but is associated with painful urination and frequency.
Flank pain, fever, chills, nausea, and vomiting usually occur only when the infection involves the kidney.
An acute UTI is identified in unspun urine only when there are more than 10 leukocytes per hpf in the unspun urine.
The normal urine may have as many as 10 WBC/per hpf without being infected.

3. Renal adenocarcinomas:
A. Are of transitional cell origin.
B. Usually are associated with anemia.
C. Are difficult to diagnose.
D. Are extremely radiosensitive.
E. Frequently are signaled by gross hematuria.

Answer: E
DISCUSSION:
Renal adenocarcinomas arise from the renal tubular cells and not from the transitional cells that line the collecting system of the kidney.
Although one fifth of all patients with renal cancer may present with anemia, the most common presenting symptom is hematuria, either gross or microscopic.
Ultrasonography may confirm that a renal lesion is either cystic or solid but computed tomography (CT) is probably the most accurate imaging study for diagnosing the disease.
Renal adenocarcinoma is little sensitive to current chemotherapeutic agents.
Radiotherapy plays almost no role in the management of the primary tumor.
Operation is the treatment of choice when the disease is confined to the kidney itself or when it has extended just outside the renal capsule.
An operation has little effect once the disease is extended to adjacent structures or to regional lymph nodes.

4. Ureteral obstruction:
A. Is associated with hematuria.
B. Is associated with deterioration of renal function and rising blood urea nitrogen (BUN) and creatinine values.
C. Is commonly caused by a urinary tract calculus.
D. Usually requires open surgical relief of the obstruction.
E. Is usually associated with infection behind the
obstruction.

Answer: C
DISCUSSION:
Ureteral obstruction produces loss of renal function when there is only one renal unit and the ureter is obstructed or when obstruction is bilateral.
Ureteral obstruction often is best identified by either intravenous pyelography(IVP) or retrograde pyelography, which allows one to identify the specific site of obstruction.
Calculous disease is the mostcommon cause of ureteral obstruction.
Ureteral obstruction is not a surgical emergency that requires open surgical intervention, but it may be relieved by retrograde or antegrade passage of a double-J stent to bypass the obstruction, permitting orderly nonemergent identification of the cause of obstruction and selection of a treatment process.

5. Stress urinary incontinence:
A. Is principally a disease of young females.
B. Occurs only in males.
C. Is associated with urinary frequency and urgency.
D. May be corrected by surgically increasing the volume of the bladder.
E. Is a disease of aging produced by shortening of the urethra.

Answer: E
DISCUSSION:
Stress urinary incontinence is seen principally in older females and is produced by pelvic floor relaxation with shortening of urethral length.
The symptom of stress urinary incontinence is urinary leakage produced by an increase in intra-abdominal pressure, as with straining to lift or to laugh.
Urgency and frequency are symptoms of urge incontinence,not stress incontinence.
Stress incontinence classically is not seen either in males or in young females who have good pelvicfloor support.

6. Which of the following is/are true of blunt renal trauma?
A. Blunt renal trauma and penetrating renal injuries are managed similarly.
B. Blunt renal trauma with urinary extravasation always requires surgical exploration.
C. Blunt renal trauma must be evaluated by contrast studies using either IVP or CT.
D. Blunt renal trauma requires exploration only when the patient exhibits hemodynamic instability.
E. Any kidney fractured by blunt renal trauma must be explored.

Answer: D
DISCUSSION:
Blunt renal trauma should be explored.
Only those who have gross hematuria need undergo contrast studies.
Microscopic hematuria is no longer an indication for contrast evaluation.
Patients who have blunt renal trauma need to undergo exploration only if they are hemodynamically unstable.
Conservative management in the absence of hemodynamic instability is the current trend.
All penetrating injuries should undergo exploration.

7. Carcinoma of the bladder:
A. Is primarily of squamous cell origin.
B. Is preferentially treated by radiation.
C. May be treated conservatively by use of intravesical agents even if it invades the bladder muscle.
D. May mimic an acute UTI with irritability and hematuria.
E. Is preferentially treated by partial cystectomy.

Answer: D
DISCUSSION:
Carcinoma of the bladder is primarily of transitional cell origin, arising from the transitional epithelium that lines the bladder. It may be confused with an acute UTI by producing urgency, frequency, and hematuria.
Bladder carcinoma may be treated conservatively using intravesical agents if the tumor is intraepithelial in origin and does not invade through the basement membrane.
Neither radiation nor chemotherapy is the treatment of choice for disease that invades the muscle of the bladder.
Partial cystectomy may be chosen only when the disease is focal and there are no mucosal changes in other parts of the bladder.

8. The major blood supply to the testes comes through the:
A. Hypogastric arteries.
B. Pudendal arteries.
C. External spermatic arteries.
D. Internal spermatic arteries.

Answer: D
DISCUSSION:
Testes arise from portions of the wolffian bodies on the genital ridge close to the kidneys; therefore, the major blood vessels from the testes arises from the aorta just below the renal arteries and are termed the # internal spermatic arteries.
Secondary blood supply to the testes comes from the # artery of the vas deferens, and a small branch from the epigastric artery termed the # external spermatic artery forms during descent of the testes from the abdomen to the scrotum.
The surgical importance of this phenomenon is that operations involving the region of the renal arteries may sacrifice the internal spermatic artery.
If the two other arteries are intact, the testes will survive; however, if the patient has had avasectomy and the artery of the vas has been sacrificed, there is a possibility of testicular atrophy, since the testicle will have to be totally dependent on the arterial supply derived from the small external spermatic artery.

9. Patients who have undergone operations for benign prostatic hypertrophy or hyperplasia:
A. Require routine rectal examinations to detect the development of carcinoma of the prostate.
B. Do not need routine prostate examinations.
C. Have a lesser incidence of carcinoma of the prostate.
D. Have a greater incidence of carcinoma of the prostate.

Answer: A
DISCUSSION:
Patients who have undergone operations for benign prostatic hyperplasia or hypertrophy have had only the inner portion of the prostate removed, which consists of the periurethral glandular structures that give rise to hyperplasia and hypertrophy.
The posterior segment of the prostate, which is compressed by the anterior (inner) portion, comprises thesurgical capsule and is left behind. The posterior portion of the prostate gland is the most frequent site of origin of prostate cancer. There is no difference in the incidence of carcinoma of the prostate in patients with benign prostatic hypertrophyand those without benign prostatic hypertrophy or those who have and have not undergone operation for prostatic hypertrophy.
Since prostate carcinoma can develop at any time in a patient's life, routine examinations and prostate-specific antigen assay are the most efficient methods of detecting this disease.

10. The male contribution to a couple's infertility is approximately:
A. 10%.
B. 25%.
C. 50%.
D. 75%.

Answer: C
DISCUSSION:
In the United States of America it has been estimated that approximately 15% of couples have difficulty with conception.
Adequate evaluation of the marital unit for infertility demands assessment of the male partner since infertile status may be attributed to the male as much as 50% of the time.
A full evaluation of the male partner is important to avoid extended fruitless evaluation and management of the female partner when the male is infertile
