12 Urology Flashcards
A 14-year-old boy presents in the ER with very severe pain of sudden onset in his right testicle. There is no fever, pyuria, or history of recent mumps. The testis is swollen, exquisitely painful, “high riding,” and with a “horizontal lie.” The cord is not tender.
What is it? Testicular torsion, a urologic emergency.
Management. Emergency surgery to save the testicle. Do not waste time doing diagnostic studies.
A 24-year-old man presents in the emergency room with very severe pain of recent onset in his right scrotal contents. There is a fever of 103°F and pyuria. The testis is in the normal position, and it appears to be swollen and exquisitely painful. The cord is also very tender.
What is it? Acute epididymitis.
Management. This is the condition that presents the differential diagnosis with testicular torsion. Torsion is a surgical emergency. Epididymitis is not. Don’t rush this guy to the OR, all he needs is antibiotic therapy. If by chance the diagnosis of testicular torsion is missed, the medicolegal implications are so bad that urologists routinely do a sonogram when they are sure the problem is epididymitis—just to completely, absolutely, unequivocally rule out torsion.
A 72-year-old man is being observed with a ureteral stone that is expected to pass spontaneously. He develops chills, a temperature spike to 104°F, and flank pain.
What is it? Obstruction of the urinary tract alone is bad. Infection of the urinary tract alone is bad. But the combination of the two is horrible: a true urologic emergency. That’s what this fellow has.
Management. Massive IV antibiotic therapy, but the obstruction must also be relieved right now. In a septic patient stone extraction would be hazardous, thus the option in addition to antibiotics would be decompression by ureteral stent or percutaneous nephrostomy.
An adult woman relates that 5 days ago she began to notice frequent, painful urination, with small volumes of cloudy and malodorous urine. For the first 3 days she had no fever, but for the past 2 days she has been having chills, high fever, nausea, and vomiting. Also in the past 2 days she has had pain in the right flank. She has had no treatment whatsoever up to this time.
What is it? Pyelonephritis.
Management. Urinary tract infections should not happen in men or in children, and thus they should trigger a workup looking for a cause. Women of reproductive age, on the other hand, get cystitis all the time, and they are treated with appropriate antibiotics without great fuss. However, when they get flank pain and septic signs it’s another story. This woman needs hospitalization, IV antibiotics, and at least a sonogram to make sure that there is no concomitant obstruction
A 62-year-old man presents with chills, fever, dysuria, urinary frequency, diffuse low back pain, and an exquisitely tender prostate on rectal exam.
What is it? Acute bacterial prostatitis.
Management. This vignette is supposed to elicit from you what you would not do. The treatment for this man is intuitive: he needs IV antibiotics—but what should not be done is any more rectal exams or any vigorous prostatic massage. Doing so could lead to septic shock.
A 33-year-old man has urgency, frequency, and burning pain with urination. The urine is cloudy and malodorous. He has mild fever. On physical examination the prostate is not warm, boggy, or tender.
The first part of this vignette sounds like prostatitis, which would be common and not particularly challenging; but if the prostate is normal on examination the ante is raised: The point of the vignette becomes that men (particularly young ones) are not supposed to get urinary tract infections. This infection needs to be treated, so ask for urinary cultures and start antibiotics— but also start a urologic workup. Do not start with cystoscopy (do not instrument an infected bladder, you could trigger septic shock). Start first with a sonogram.
You are called to the nursery to see an otherwise healthy-looking newborn boy because he has not urinated in the first 24 hours of life. Physical examination shows a big distended urinary bladder.
What is it? Kids are not born alive if they have no kidneys (without kidneys, lungs do not develop). This represents some kind of obstruction. First look at the meatus: it could be simple meatal stenosis. If it is not, posterior urethral valves is the best bet.
Management. Drain the bladder with a catheter if it passes easily (it will pass through the valves). Voiding cystourethrogram for diagnosis, endoscopic fulguration or resection for treatment.
A bunch of newborn boys are lined up in the nursery for you to do circumcisions. You notice that one of them has the urethral opening in the ventral side of the penis, about midway down the shaft.
What is it? Hypospadias.
The point of the vignette is that you don’t do the circumcision. The foreskin may be needed later for reconstruction when the hypospadias is surgically corrected.
A newborn baby boy has one of his testicles down in the scrotum, but the other one is not. On physical examination the missing testicle is palpable in the groin. It can easily be pulled down to its normal location without tension, but it will not stay there; it goes back up.
What is it? This is a retractile testicle, due to an overactive cremasteric reflex.
Management. Nothing needs to be done now. Even truly undescended testicles may spontaneously descend during the first year of life. Those that do not require orchidopexy.
A 9-year-old boy gives a history of 3 days of burning on urination, with frequency, low abdominal and perineal pain, left flank pain, and fever and chills.
What is it? Little boys are not supposed to get urinary tract infections. There is more than meets the eye here. A congenital anomaly has to be ruled out.
Management. Treat the infection of course, but do IVP and voiding cystogram looking for reflux. If found, long-term antibiotics while the child “grows out of the problem.”
A mother brings her 6-year-old girl to you because “she has failed miserably to get proper toilet training.” On questioning you find out that the little girl perceives normally the sensation of having to void and voids normally and at appropriate intervals, but also happens to be wet with urine all the time.
What is it? A classic vignette: low implantation of one ureter. In little boys there would be no symptoms, because low implantation in boys is still above the sphincter, but in little girls the low ureter empties into the vagina and has no sphincter. The other ureter is normally implanted and accounts for her normal voiding pattern.
Management. If the vignette did not include physical exam, that would be the next step, which might show the abnormal ureteral opening. Often physical examination does not reveal the anomaly, and imaging studies would be required (start with IVP). Surgery will follow.
A 16-year-old boy goes on a beer-drinking binge for the first time in his life. Shortly thereafter he develops colicky flank pain.
What is it? Another classic. Ureteropelvic junction obstruction.
Management. Start with ultrasound (sonogram). Repair will follow.
A 62-year-old man reports an episode of gross, painless hematuria. Further questioning determines that the patient has total hematuria rather than initial or terminal hematuria.
What is it? The blood is coming anywhere from the kidneys to the bladder, rather than the prostate or the urethra. Either infection or tumor can produce hematuria. In older patients without signs of infection, cancer is the main concern, and it could be either renal cell carcinoma or transitional cell cancer of the bladder or ureter.
Management. Do a CT scan and cytoscopy.
A 70-year-old man is referred for evaluation because of a triad of hematuria, flank pain, and a flank mass. He also has hypercalcemia, erythrocytosis, and elevated liver enzymes.
What is it? Full-blown picture of renal cell carcinoma (very rarely seen nowadays).
Management. Do a CT scan.
A 55-year-old chronic smoker reports three instances in the past 2 weeks when he has had painless, gross, total hematuria. In the past 2 months he has been treated twice for irritative voiding symptoms, but has not been febrile, and urinary cultures have been negative.
What is it? Most likely bladder cancer but must exclude renal etiology.
Management. Do a CT scan and cytoscopy.
