Urology š¤¢ Flashcards
What is the CLASSIC timeline of hemolytic uremic syndrome?
Prodrome with BLOODY diarrhea, vomiting, and abdominal pain
Followed by the classic TRIAD:
- Hemolytic anemia
- Thrombocytopenia
- Acute Kidney Injury
Which one requires emergency treatment:
Phimosis or Paraphimosis
Paraphimosis
What disease:
Throat, bloat, coke
Post infectious glomerulonephritis
Throat: happens after GAS pharyngitis
Bloat: edema (periorbital or peripheral)
Coke: urine looks like coke
What is this:
Inability to retract foreskin
Phimosis
If you suspect a UTI, what labs do you need to order?
Urinalysis
Culture and sensitivities
What will you see in the urinalysis of someone with post-infectious glomerulonephritis?
Cola colored
RBC too numerous to count
RBC Casts (PATHOGNOMIC for GN)
How do you treat Pathologic phimosis?
Stretching exercises (gently pulling it back QID)
Topical steroid
Circumcision (last resort)
Is a vesicoureteral reflux common?
Yes. 1% of newborns have it, and 30-45% of children with UTIs have it
What will you see in the Urinalysis if your patient has UTI?
Bacteriuria
Pyuria
Leukocyte esterase (from breakdown of WBC)
Nitrite (produced by G- rods)
What is this:
Abnormal penile curvature
Chordee
Is it really obvious when a child has a horseshoe kidney?
No, usually asymptomatic
Maybe they have pain, infection or obstruction
What is this:
āRetracted foreskin in an uncircumcised male that cannot be returned to its natural positionā
Paraphimosis
What is the most common renal malignancy in kids?
Wilms Tumor
(Risk increases if you have a horseshoe kidney_
Is red urine always hematuria?
No, it may be from eating beets, pyridium, or food dyes
A thorough history is KEY

- Joint pain usu knees and ankles
- Renal involvement
What are some of the downsides to a Voiding Cystourethrogram?
Invasive
Radiation
Catheter
Cost
Discomfort
MANY cases of vesicoureteral reflux will go away on their own
What is the problem with using DDAVP/Desmopressin for nocturnal enuresis?
It is effective short term, but has a high relapse rate
What is the first line imaging study for following up in a UTI (in patients for whom it is indicated)
Renal and Bladder Ultrasound (RBUS)*****
What are you thinking:
Hereditary glomerulonephritis affecting collagen proteins in kidneys, eyes, and ears
Alport Syndrome
What is the range of grades for vesicoureteral reflux?
***
Grade 1(mild)-5(severe) **************
IMPORTANT
What are the benefits of circumcsion?
UTI less likely
Some STIs less likely
Penis cancer less likely
Inflammation/dermatoses less likely
What is the most common bacteria in UTI?
E. Coli 80% of the time
Others are klebsiella, proteus, enterococcus, Staph aureus
True or False:
Circumcision leads to sexual dissatisfaction and breast feeding failure
False
Though it is true that Babby may not BF for 24 hrs after the procedure
What is cryptorchidism?
The scrotum is missing a testicle and it hasnāt descended bony 4 moths of age
What might make you suspect that a child has a vesicoureteral reflux?
- seeing hydronephrosis on a prenatal ultrasound
- a child with a febrile UTI
Do AAP guidelines recommend routine screening UA in asymptomatic, healthy patients?
No

If they also have one of these:
- any anomaly on RBUS
- Temp >102.2 and pathogen other than E. coli
- poor growth
- HTN
In testicular torsion:
After _____ hours, the testis is 100% viable
After _____ hours, the testis is 20% viable
After ____ hours, the testis is 0% viable
4-6 hours=100%
12 hours= 20%
24 hours= 0%
What might cause foamy urine?
Proteinuria
What are the two types of circumcision ?
Gomco- a can opener?!? Seriously have no idea what this is about and Iām done looking at that picture
Plastibell-putting a tube around it and tying it tight until the tissue dies ?!?!?
How do you treat testicular torsion
Immediate urology consult
Surgical detorsion and fixation (orchiopexy) of BOTH testes so it doesnt happen again
If imaging is needed for evaluation of UTI, what is the first line study?
Renal and Bladder ultrasound (RBUS)
What is this:
