the left can b ligated from the IVC 2/2 increased collaterals

4

what is the most common type of kidney stone?

calcium oxalate

5

which type of kidney stone do pts get who have had their TI resected?

calcium oxalate: due to increased oxalate absorption in colon

6

what are and what causes struvite stones?

magnesium ammonium phosphate stones, cause staghorn calculi, occur w infections (proteus mirabilis) that are urease producing

7

which kidney stones are radiolucent?

uric acid and cysteine

8

which patients (3) are more at risk for uric acid stones?

- ileostomies, gout and myelopoliferative disorders

9

what drug is used to prevent cysteine stones?

tiopronin

10

how do you resect testicular cancer?

inguinal incision- scrotal incisions will disrupt the lymphatics

11

what level correlates with testicular ca tumor bulk ?

LDH

12

MC types of testicular ca

germ cell: seminoma and non-seminoma (90%)

13

diagnosis and management of seminoma

- 10% have elevated b-hcg, do NOT hav elevated AFP
ALL get orchiectomy and retroperitoneal XRT

14

diagnosis and management of non-seminoma testicular ca

- 90% have elevated AFP and B-HCG
ALL get orchiectomy and RP LN dissection
Stage 2 or greater: Chemo

15

what chemotherapy agents do you give in testicular ca?

cisplatin, bleomycin, VP-16

16

how do you proceed when you get stage I prostate ca after a TURP?

nothing else

17

when do you give XRT and androgen ablation in prostate ca?

extracapsular invasion (T3+) or metastatic disease

18

#1 primary tumor of the kidney

RCC

19

isolated lung or colon mets

20

MC location of RCC mets?

lung

21

#1 tumor of the kidney

mets from breast ca

T2 invades into muscle wall, manage w cystectomy w ileal conduit, chemo (MVAC: methotrexate, vinblastine, adriamycin, cisplatin) and XRT

26

squamous cell ca of bladder is related to what?

schistosomiasis infection

27

what layer hypertrophies in BPH?

transitional zone

28

initial therapy of BPH?

alpha blockers: terazosin, doxazosin (relax smooth muscle)
5-alpha-reductase inhibitors: finasteride

29

MOA finasteride

5-alpha-reductase inhibitors
inhibits conversion of testosterone to dihydrotestosterone, inhibits prostate hypertrophy

30

MC complication of TURP

retrograde ejaculation
