Robbins, Chapter 21, Lower UT and Male GU System Flashcards
(77 cards)
What is the significance of urinary stasis in diverticulae?
Increased propensity for infection and formation of bladder calculi.
Patients with exstrophy have increased risk of what neoplasm and where?
adenocarcinoma in bladder remnant
Child with recurrent UTI, think what?
Vesicoureteral Reflux (1/3 of kids with recurrent UTIs have have this)
4yo F with abdominal pain and fever. CT showed heterogeneous mass in midline, anterior to bladder. What could this be?
Infected urachal remnant/cyst.
What two pathologies may arise within urachal cyst or patent urachus?
Carcinomas or infection
Woman from Egypt (schisto) OR E coli, Proteus, Klebsiella, Enterobacter. OR immunocompromised person (candida) OR sequel to renal tuberculosis Think what?
Bacteria pyelonephritis
What does this triad indicate?
(1) Frequency
(2) lower abdominal pain localized over bladder region
(3) dysuria (pain/burning urination)
Also, low grade fever, turbid urine, and occasional hematuria.
Cystitis
30-40yoF comes in with intermittent, severe suprapubic PAIN, urinary frequency, urgency, hematuria and dysuria negative urine cultures for bacteria.
Chronic mucosal ulcers (Hunner ulcers) are associated with what?
Cytoscopic findings of fissures and punctate hemorrhages in bladder mucosa after luminal distention. MAST CELLS, lymphocytes, fibrosis and inflammation of the bladder wall.
Interstitial Cystitis (Chronic Pelvic Pain Syndrome)
Middle aged F»M.
Arises in setting of chronic bacteria infection (E. COLI or Proteus), occurs more in IMMUNOSUPPRESSED TRANSPLANT PATIENTS.
See slightly raised, broad, flat mucosal plaques.
Michaelis-Gutmann bodies present in macrophages in areas that form granulomas.
Malakoplakia (cystitis)
Number of organisms indicative of UTI in women v. men/asymptomatic women.
Women - 100organisms/mL + pyuria
Men/asymptomatic - 1000organisms/mL
When should a negative urine culture be reexamined?
When the patient is on antimicrobial therapy when the culture is obtained.
All of the following are predisposing factors for what?
- Bladder calculi, urinary obstruction/structural abnormalities, DM, instrumentation, immune deficiency.
- Radiation of bladder
Acute cystitis
Acute/chronic irradiation cystitis
TNTC WBCs in urine indicative of what?
Acute cystitis
Antecedent bacterial cystitis can progress to what?
Mortality increased in patients with what preexisting disease?
Pyelonephritis
Diabetes
A patient on anti-tumor drugs OR who has an adenovirus infection can develop what?
Hemorrhagic Cystitis
What am I?
Person had an indwelling catheter that resulted in irritation of the bladder mucosa.
Polyploid urothelium results from extensive submucosal edema. May be misdiagnosed as papillary carcinoma.
Polyploid cystitis
CHILD 4yo (M=F). Malignant mesenchymal tumor.
Rare.
??”Grape like”??
Rhabdomyosarcoma (Sarcoma botryoides)
ADULT 60yo (2M>1F), some post-RaRx or chemoRx. Malignant mesenchymal tumor, typically of adults. Rare
Leiomyosarcoma
ADULT 65yo 1M
Non-epithelial malignancy
Name the 5 types of urothelial (transitional cell tumors) that make up more than 90% of the tumors of the urinary bladder.
M or F?
W or B?
White males have highest risk! Industrial > Non Urban > Rural.
Exophytic papilloma
Inverted papilloma
Carcinoma in situ
Papillary urothelial neoplasm of low malignant potential - PUNLMP
Low grade and high grade papillary urothelial cancers
Thickened epithelium covering papillary projections is the major pathologic finding of what neoplasm?
Papillary urothelial neoplasm of low malignant potential - PUNLMP
What are the known (7) risk factors of urothelial neoplasia?
Known genetic risk factors? Ch# deletion (two), which has p53 associated (is this good or bad?)
CIGARETTE SMOKING (Industrial) dyes Cyclophosphamide Phenacetin Schisto Long term analgesic use Radiation
Ch 9 monosomy or deletions - superficial and non invasive, some invasive
Ch 17p deletion -invasive and CIS; p53 (BAD prognostic sign)
Describe pt presentation:
Flat lesions
Papillary lesions
Flat - discomfort likely
Papillary - hematuria likley
73yo white male presents with PAINLESS HEMATURIA. May also have frequency, urgency dysuria. Atypical cells seen in urine cytology.
What is the dx? What is the frequency of finding multiple tumors upon initial diagnosis?
Urothelial Carnicoma
40% have multiple tumors upon initial diagnosis.
