- Prolonged catheter use, calculi
What is the MC type of bladder cancer?
Epithelial (98%), usually urothelial cell carcinomas
What is the MC presenting symptom of bladder cancer?
Hematuria (gross or microscopic) in 85-90% of pts
How is bladder cancer diagnosis confirmed?
Cystoscopy with biopsy
Treatment of superficial bladder cancer
Lesion resection and intravesical chemo
Treatment of invasive but localized bladder cancer
- Radical cystectomy
- Chemo and RT
Treatment of muscle invasion bladder cancer
Systemic chemo prior to radical cystectomy
Define intravesical chemo
Chemo delivered directly to bladder weekly x 6-12 weeks
What is the only identifiable risk factor for renal cell carcinoma?
Smoking
Who is MC affected by renal cell carcinoma?
2:1 males
6th decade of life
Where does renal cell carcinoma originate from?
Proximal tubule cells
Treatment of renal cell carcinoma
- Partial nephrectomy (small tumors)
- Radical nephrectomy (large tumors)
- No effective chemo for mets renal cell cancer
Prognosis of renal cell carcinoma
- 90-100% 5 yr survival when tumor is confined to renal capsule
- 50-60% 5 yr survival for tumors beyond renal capsule
- 0-15% for node positive tumors
Prognosis of bladder cancer
- 98% 5 yr survival for superficial in situ
- 88% 5 yr survival for Stage I
What is Wilms’ tumor?
- Rare kidney cancer that primarily affects children (3-4 yo, less likely after 5 yo)
- Aka nephroblastoma
What is the MC kidney cancer in children?
Wilms’ tumor
Prognosis of Wilms’ tumor
5 yr survival rate over 90%
What type are most prostate cancers?
Adenocarcinoma (over 95%)
How is histologic aggressiveness of prostate cancer measured?
Gleason grading system
MC clinical presentation of prostate cancer
Many pts asymp (60%)
Prognosis of prostate cancer
Overall 10 yr survival 70-80%
What is the MC cancer in men 20-35 yo?
Testicular
Main types of testicular cancer
- Nonseminomas (65%)
- Seminomas (35%)
Key features of testicular cancer
- MC in cryptorchidism
- MC on right testicle
What is the MC clinical presentation of testicular cancer?
Painless enlargement of testis
When do recurrences of testicular cancer occur?
80% of recurrences occur in first 2 years (so early surveillance after treatment is necessary)
Prognosis of testicular cancer
Excellent 5 yr survival (55-100%)
Testicular self exams
- Have not been studied enough to show benefit
- No recommendation on monthly self exams
- High risk pt should have awareness (undescended testicle, fam hx)
Describe polycystic kidney disease
- Multiple cysts in bilateral kidneys
- Many different types including autosomal dominant
- Hereditary disorder

- ADPKD1 on chromosome 16 (85-90% pts)
- ADPKD2 on chromosome 4 (10-15% pts)
What confirms diagnosis of PKD?
US
Treatment of PKD
- BP monitoring (keep under 125/75)
- Tx UTI and stones
- Avoid contact sports if enlarged kidneys
What are PKD patients at risk for?
Cerebral aneurysm
Prognosis of PKD
- 50% will have ESRD by 60 yo
- 10% of pts on dialysis have PKD
