Presentation of low implantation of a ureter?

A

Asymptomatic in little boys

Fascinating clinical presentation in little girls -> feels the need to void, voids normally at appropriate intervals (urine deposited into the bladder by the normal ureter), but is also wet with urine all the time (urine that drips into the vagina from the low-implanted ureter)

Q

Presentation of UPJ obstruction?

A

Allows normal urinary output to flow without difficulty, but if a large diuresis occurs, the narrow area cannot handle it

Classic presentation -> adolescent who goes on a beer-drinking binge for the first time in his life, develops colicky flank pain

22
Q

Most common presentation for cancer of the kidney, ureter, or bladder?

A

Hematuria

23
Q

Work-up of hematuria?

A

Start with CT scan

Continue with cystoscopy (only reliable way to r/o cancer of the bladder)

24
Q

Presentation of renal cell carcinoma?

A

Hematuria, flank pain, flank mass

Can also produce hypercalcemia, erythrocytosis, elevated liver enzymes

25
Q

CT appearance of renal cell carcinoma?

A

Heterogenic solid tumor; possible growth into the renal vein and vena cava, which could become a lethal PE if dislodged during the nephrectomy

26
Q

Rx renal cell carcinoma?

A

Surgery - only effective therapy

27
Q

Cancer of the bladder (___ in most cases) has a very close correlation with ___.

A

Transitional cell carcinoma; smoking

28
Q

Presentation of bladder cancer?

A

Hematuria
Sometimes irritative voiding symptoms
Many have been treated for UTI even though cultures were negative and they were febrile

29
Q

Dx bladder cancer?

A

Start with CT scan

Cystoscopy (best way to diagnose)

30
Q

Rx bladder cancer?

A

Surgery and intravesical BCG

Very high rate of local recurrence makes lifelong close follow-up a necessity

31
Q

Presentation of prostatic cancer?

A

Incidence increases with age

Most asymptomatic and have to be sought by rectal exam (rock-hard discrete nodule) and PSA (elevated for age group)

32
Q

Dx prostate cancer?

A

Transrectal needle biopsy (guided by sonogram when discovered by PSA)

CT helps assess extent and choose therapy

33
Q

Rx prostate cancer?

A

Surgery and/or radiation

Widespread bone mets respond for a few years to androgen ablation, surgical (orchiectomy) or medical (LH-releasing hormone agonists, or anti-androgens like flutamide)

34
Q

Presentation of testicular cancer?

A

Young men

Painless testicular mass

35
Q

Work-up suspected testicular cancer?

A

Because benign testicular tumors are virtually non-existent, biopsy is done with a radical orchiectomy by the inguinal route.

Blood samples pre-op for serum markers (AFP, Beta-hCG) to use for follow-up

LN dissection in some cases

36
Q

Rx testicular cancer?

A

As above, plus radiation and chemo (platinum-based)

37
Q

Presentation of acute urinary retention?

A

Very common in men who already have significant symptoms from BPH

Often precipitated during a cold by the use of antihistamines and nasal drops, and by abundant fluid intake

Patient wants to void but cannot
Palpable distended bladder

38
Q

Management of acute urinary retention?

A

Indwelling bladder cath placed and left in for at least 3 days

First line of long-term therapy is alpha-blockers (most selective is tamsulosin); 5-alpha-reductase inhibitors (finasteride or dutasteride) are for very large glands (>40 g)

Minimally invasive procedures using thermal ablation of prostatic tissue have not gained popularity

Transurethral resection of the prostate (TURP) remains the final surgical option for BPH

39
Q

Presentation of post-op urinary retention?

A

Very common, sometimes masquerades as incontinence

May not feel the need to void because of post-op pain, meds, etc., but will report that every few minutes there is involuntary release of small amounts of urine

Huge distended bladder will be palpable

40
Q

Manage post-op urinary retention?

A

Indwelling bladder cath

41
Q

Presentation of stress incontinence?

A

Very common in middle-age women who have had many pregnancies and vaginal delivers

Leak small amounts of urine whenever intra-abdominal pressure increases (sneezing, laughing, getting out of a chair, lifting a heavy object)

No nighttime incontinence

Exam - weak pelvic floor, prolapsed bladder neck outside of the “high-pressure” abdominal area

42
Q

Rx stress incontinence?

A

Pelvic floor exercises may be sufficient for early cases

Surgical repair of the pelvic floor is indicated in advanced cases with large cystoceles

43
Q

Presentation of passage of ureteral stones?

A

Classic colicky flank pain with irradiation to the inner thigh and labia or scrotum, and sometimes N/V

44
Q

Dx ureteral stones?

A

CT scan

45
Q

Management of ureteral stones?

A

Small (3 mm or less) at ureterovesical junction have a 70% chance of passing spontaneously -> analgesics, fluids, watchful waiting

7-mm stone at the UPJ only has a 5% probability of passing

Intervention: most common tool used is extracorporeal shock-wave lithotripsy (ESWL)

Other options - basket extraction, sonic probes, laser beams, open surgery

Everyone - abundant water intake for prevention

46
Q

Contraindications to ESWL?

A

Pregnant women, bleeding diathesis, stones that are several cm large

47
Q

Pneumaturia is almost always caused by ___, most commonly the ___, and most commonly from ___.

A

Fistulization between the bladder and GI tract; sigmoid colon; diverticulitis

(second possibility is cancer of the sigmoid, distant third - bladder cancer)

48
Q

Work-up and Rx of pneumaturia?

A

Start with CT (will show inflammatory diverticular mass)

Sigmoidoscopy later to r/o cancer

Surgical therapy

49
Q

Presentation of psychogenic impotence?

A

Sudden onset
Partner or situation specific
Does not interfere with nocturnal erections
Can be effectively treated with psychotherapy ONLY if done promptly

50
Q

Presentation of organic impotence?

A

If caused by trauma - sudden onset, specifically related to traumatic event (after pelvic surgery 2/2 nerve damage or after trauma to the peritoneum 2/2 arterial disruption)

If caused by chronic disease (arteriosclerosis, DM) - very gradual onset, going from erections not lasting long enough, to being of poor quality, to not happening at all including at night

51
Q

Rx impotence?

A

Sildenafil, tadalafil, vardenafil

Many other options - vascular surgery (well-suited if arterial injury), suction devices (almost anyone), prosthetic implants (irreversible and fraught with complications)
