Answers
1.a. Obstruction of urine flow with distention of the renal capsule. Pain is usually caused by acute distention of the renal capsule, usually from inflammation or obstruction.
2.c. Bladder cancer. The most common cause of gross hematuria in a patient older than age 50 is bladder cancer.
3.b. Ureteral obstruction due to blood clots. Pain in association with hematuria usually results from upper urinary tract hematuria with obstruction of the ureters with clots.
4.d. Dysuria. Dysuria is painful urination that is usually caused by inflammation.
5.d. Vesicovaginal fistula. Continuous incontinence is most commonly due to a urinary tract fistula that bypasses the urethral sphincter or an ectopic ureter.
6.e. Cerebrovascular accidents. Anejaculation may result from several causes:
(1) androgen deficiency, (2) sympathetic denervation, (3) pharmacologic agents, and (4) bladder neck and prostatic surgery.
7.b. 5%. In fact, 5% of patients with previously undiagnosed multiple sclerosis present with urinary symptoms as the first manifestation of the disease.
8.e. Mobility/fixation of pelvic organs. In addition to defining areas of induration, the bimanual examination allows the examiner to assess the mobility of the bladder; such information cannot be obtained by radiologic techniques such as computed tomography (CT) and magnetic resonance imaging (MRI), which convey static images.
9.b. Sickle cell anemia. Priapism occurs most commonly in patients with sickle cell disease but can also occur in those with advanced malignancy, coagulation disorders, and pulmonary disease, as well as in many patients without an obvious cause.
.c. Phosphaturia. Cloudy urine is most commonly caused by phosphates in the urine.
.d. Dehydration. Conditions that decrease specific gravity include (1) increased fluid intake, (2) diuretics, (3) decreased renal concentrating ability, and (4) diabetes insipidus.
.c. 50 and 1200 mOsm/L. Osmolality is a measure of the amount of solutes dissolved in the urine and usually varies between 50 and 1200 mOsm/L.
.a. Glucose. False-negative results for glucose and bilirubin may be seen in the presence of elevated ascorbic acid concentrations in the urine.
.c. Microscopic presence of erythrocytes. Hematuria can be distinguished from hemoglobinuria and myoglobinuria by microscopic examination of the centrifuged urine; the presence of a large number of erythrocytes establishes the diagnosis of hematuria.
.c. 25%. Investigators at the University of Wisconsin found that 26% of adults who had at least one positive dipstick reading for hematuria were subsequently found to have significant urologic pathologic findings.
. c. Berger disease (immunoglobulin A [IgA] nephropathy). IgA nephropathy, or Berger disease, is the most common cause of glomerular hematuria, accounting for about 30% of cases.
. b. Excessive glomerular permeability due to primary glomerular disease.
Glomerular proteinuria is the most common type of proteinuria and results from increased glomerular capillary permeability to protein, especially albumin. Glomerular proteinuria occurs in any of the primary glomerular diseases such as IgA nephropathy or in glomerulopathy associated with systemic illness such as diabetes mellitus.
.e. Ureteroscopy. Transient proteinuria occurs commonly, especially in the pediatric population, and usually resolves spontaneously within a few days. It may result from fever, exercise, or emotional stress. In older patients, transient
proteinuria may be due to congestive heart failure.
.d. 180 mg/dL. This so-called renal threshold corresponds to a serum glucose level of about 180 mg/dL; above this level, glucose will be detected in the urine.
.e. > 90%. The specificity of the nitrite dipstick test for detecting bacteriuria is greater than 90%.
.d. Presence in clumps. Squamous epithelial cells are large, have a central small nucleus about the size of an erythrocyte, and have an irregular cytoplasm with fine granularity.
.c. 5. Therefore 5 bacteria per high-power field in a spun specimen reflect colony counts of about 100,000/mL.
.b. Bladder or urethral inflammation. Pain in the flaccid penis is usually secondary to inflammation in the bladder or urethra, with referred pain that is experienced maximally at the urethral meatus.
.d. Hydrocele. Chronic scrotal pain is usually related to noninflammatory conditions such as a hydrocele or varicocele, and the pain is usually characterized as a dull, heavy sensation that does not radiate.
.a. Bladder neck or prostatic inflammation. Terminal hematuria occurs at the end of micturition and is usually secondary to inflammation in the area of the
bladder neck or prostatic urethra.
.b. 15%. Enuresis refers to urinary incontinence that occurs during sleep. It occurs normally in children as old as 3 years but persists in about 15% of children at age 5 and about 1% of children at age 15.
.a. Sudden onset. A careful history will often determine whether the problem is primarily psychogenic or organic. In men with psychogenic impotence, the condition frequently develops rather quickly, secondary to a precipitating
event such as marital stress or change or loss of a sexual partner.
.a. Cystoscopy. A genital and rectal examination should be done to exclude the presence of tuberculosis, a PSA assessment and digital rectal examination
should be done to exclude prostatic carcinoma, and a urinary cytologic assessment should be done to exclude the possibility of transitional cell carcinoma of the prostate.
.e. Ectopic ureter. Pneumaturia is the passage of gas in the urine. In patients who have not recently had urinary tract instrumentation or a urethral catheter placed, this is almost always due to a fistula between the intestine and bladder.
Common causes include diverticulitis, carcinoma of the sigmoid colon, and regional enteritis (Crohn disease).
.a. Parkinson disease. The second important example of nonspecific lower urinary tract symptoms that may occur secondary to a variety of neurologic conditions is irritative symptoms resulting from neurologic disease such as cerebrovascular accident, diabetes mellitus, or Parkinson disease.
Chapter review
1.See Table 1-1 in Campbell-Walsh Urology, 11th edition for the International Prostate Symptom Score (IPSS).
2.IPSS score: 0 to 7 mild symptoms, 8 to 19 moderate symptoms, 20 to 35 severe symptoms.
3.Renal pain radiates from the flank anteriorly to the respective lower quadrant and may be referred to the testis, labium, or medial aspect of the thigh. The pain is colicky (fluctuates). It may be associated with gastrointestinal symptoms due to reflex stimulation of the celiac ganglion.
4.Patients with slowly progressive urinary obstruction with bladder distention often have no pain, despite residual volumes in excess of a liter.
5.Pain of prostatic origin is poorly localized.
6.Scrotal pain may be primary or referred. Pain referred to the testicle originates in the retroperitoneum, ureter, or kidney.
7.Hematuria, particularly in adults, should be regarded as a symptom of malignancy until proven otherwise.
8.Adults normally arise no more than twice a night to void. Urine production increases at night (recumbent position) in older patients and those with cardiac disease, particularly congestive heart failure (CHF).
9.Postvoid dribbling: Urine escapes into the bulbar urethra and then leaks at the end of micturition. This may be alleviated by perineal pressure
following voiding.
10.Those who present with microscopic hematuria and irritative voiding symptoms should be suspected of having carcinoma in situ of the bladder until proven otherwise.
11.Continuous incontinence is most commonly due to ectopic ureter, urinary tract fistula, or totally incompetent sphincter.
12.Hematospermia almost always resolves spontaneously and is rarely associated with any significant urologic pathology.
13.When urinary obstruction is associated with fever and chills, it should be regarded as a urologic emergency.
14.It is always worthwhile to obtain the previous operative report in patients who are to be operated on.
15.If the patient is uncircumcised, the foreskin must be retracted for inspection of the glans.
16.The testes are normally 6 cm in length and 4 cm in width.
17.If one obtains a stool guaiac test (hemoccult) as a screen for colon cancer, two subsequent stool specimens must be obtained for an adequate test. If the hemoccult is positive, the patient should be on a red meat–free diet for 3 days before collection of three specimens.
18.A male urologist should always perform a female pelvic examination with a female nurse in attendance.
19.The bulbocavernosus reflex tests the integrity of this spinal cord reflex involving S2 to S4.
20.A positive dipstick for blood in the urine indicates hematuria, hemoglobinuria, or myoglobinuria. Hematuria is distinguished from hemoglobinuria and myoglobinuria by microscopic examination of the centrifuged urine and identification of red blood cells (more than three red blood cells per high-power field is abnormal).
21.Hematuria of nephrologic origin is frequently associated with proteinuria and dysmorphic erythrocytes.
22.Anticoagulation at normal therapeutic levels does not predispose patients to hematuria.
23.The most accurate method to diagnosis urinary tract infection is by microscopic examination of the urine and identifying pyuria and bacteria. This is confirmed by urine culture.
24.The chief complaint is the focus of the visit and is the reason the patient seeks consultation. It should be the lead sentence in the History and
Physical (H&P).
25.A family history should always include questions about renal and prostate cancer, renal cysts, and stone disease.
26.Priapism occurs most commonly in patients with sickle cell disease but can also occur in those with advanced malignancy, coagulation disorders, or pulmonary disease, as well as in many patients without an obvious cause.
27.On urine dipstick, false-negative results for glucose and bilirubin may be seen in the presence of elevated ascorbic acid concentrations in the urine.
28.Glomerular proteinuria is the most common type of proteinuria and results from increased glomerular capillary permeability to protein, especially albumin. Glomerular proteinuria occurs in any of the primary glomerular diseases such as IgA nephropathy or in glomerulopathy associated with systemic illness such as diabetes mellitus.
29.Five bacteria per high-power field in a spun specimen reflect colony counts of about 100,000/mL.
30.An important example of nonspecific lower urinary tract symptoms that may occur secondary to a variety of neurologic conditions is irritative symptoms resulting from neurologic disease such as cerebrovascular accident, diabetes mellitus, and Parkinson disease.
31.The renal threshold for glucose corresponds to a serum glucose level of about 180 mg/dL; above this level, glucose will be detected in the urine.
