URO TMR Flashcards
Transitional cell epithelium lines the urinary tract from the renal pelvis up to the ________
proximal 2/3 of the urethra
What is the most frequent risk factor of urothelial tumors?
tobacco use
This symptom occurs in 85% of patients with urothelial tumors
Painless gross hematuria
The following are true regarding recurrent significant hematuria EXCEPT
a. >3 RBCs/HPF on 2 urinalysis
b. single urinalysis with >100 RBCs
c. Gross hematuria
d. NOTA
A; 3x
Recurrent significant hematuria of
- > 3 RBCs/HPF on 3 urinalysis
- single urinalysis with >100RBCx
- Gross Hematuria
is associated with renal or urologic lesions in what percentage of patients
9.1%
True about detection of urothelial cancer EXCEPT
a. patients with microscopic hematuria require a full evaluation
b. low-risk patients do not require repeat evaluations
c. High risk individuals primarily those with history of smoking should be evaluated every 3 months.
d. the level of suspicion for urogenital neoplasms in patients with isolated plainless hematuria and nondysmorphic RBCs increases with age.
e. NOTA
C; should be evaluated every 6 months
What is the gold standard for tumor detection
White light cystoscopy with random bladder biopsies
True about history and staging of urothelial tumors
a. Low-grade papillary lesions are likely to recur in up to 10% of patients but invade in up to 60% of cases
b. High grade lesions also recur, invasion and subsequent stage progression can occur in 40% of the tumors
c. The most important risk factor for progression of urothelial tumors is grade.
D. NOTA
C
a. 60%, 10%
b. 50%
Bladder cancer that is confined to the bladder mucosa or submucosa
non muscle invasive bladder CA
Non- muscle invasive Bladder CA can be managed with
TUR alone and adjuvant intravesical chemotherapy/immunotherapy
Patient with non muscle invasive bladder CA, diffuse CIS, recurrent disease, >40% involvement of the bladder surface by tumor.
Is intravesical treatment advised?
yes
True of TURBT
a. TURBT is performed both to remove all visible tumors and to provide specimens for pathologic examination to determine stage and grade
b. repeat resection within 2-4 weeks is usually indicated in patients with high grade disease
c. Single dose intravesical chemo within 24 hours of resection reduces recurrence of low-risk tumors
d. all suspicious lesions should be sampled. random biopsies are required in low risk patients
A
b. 3-6 weeks
c. 6 hours
d. random biopsies are not required
True about medical therapy for urothelial tumors EXCEPT
a. intravesical BCG has higher efficacy than intravesical chemo
b. BCG is the only agent shown to delay or reduce high-grade tumor progression.
c. standard therapy is bacillus calmette- guerin in 8 weekly instillations followed by maintaenance administrations for >1 year.
d. BCG is contraindicated in the setting of disrupted urothelium because of the risk of intravasation and septic death
C. 6 weekly installations
diagnostic modalities used for surveillance of upper tract recurrence
retrograde pyelogram or CT urograms
How often should patients be monitored for recurrence of urothelial tumors
3 month intervals during the 1st year
