Urologic Emergencies Flashcards
Non-traumatic urological emergencies
- Urolithiasis/Renal Colic 2. Urinary Retention
- Infections
- Hematuria
- Acute Scrotum
- Paraphimosis
- Priapism
- Fourniers gangrene
Kidney stones
Accumulation of normally dissolved solids from kidney form a stone. Once 2-3mm in size become symptomatic with pain and obstructing the ureter.
When do kidney stones become symptomatic
2-3 mm in size IN URETER
Most common kidney stone
Calcium salts (radiopaque)
types of stones
•Calcium salts- most common- radiopaque •Struvite- associated with infection-
radiopaque
•Uric acid- associated with Gout-radiolucent •Cystine- rare
Sx of renal colic
- The Unilateral Flank pain is characteristically :
- Very sudden onset- Colicky
- Radiates to the groin as the stone passes into the lower ureter.
- May change in location, from the flank to the groin
- The patient cannot get comfortable, and may roll around in agony. Pain equal to labor
- Associated with nausea / Vomiting • Urinary frequency- dark urine
PE for renal colic
abdomen, back, chest
Male GU
female +/- pelvic
VS - temp and BP
Labs for renal colic
u/a - hematuria Bun/Cr- renal compromise KUB x-ray Non-contrast CT scan* Renal US (pregnant, children, pt w/ previous hx stones) - detects hydronephrosis
Spontaneous expulsion chances
> 5-6 = urologic intervention
most are 2-4; pencil eraser diameter = 6mm
Tx for renal colic
pass if <5mm; not pass if >8 mm
Pain relief, antinausea, abx, alpha 1 blockers, watchful waiting
Admit if “sick”
Temporary relief if not passing on own - insert JJ stent of percutaneous nephrostomy tube
Definitive tx (intractable pain, fever, renal function, 4 weeks) - ESWL (lithotripsy), PCNL (nephrolithotomy), ureteroscopy, open surgery
Meds for renal colic
stones <4-5 mm (no benefit)
Stones 5-10 - increase passage (NNT5)
Acute urinary retention : what is it?
painful inability to void, w/ relief following drainage of the bladder by cath; OBSTRUCTIVE - BPH most common (>50YO), infection of prostate, constipation
Most common cause of acute urinary retention
BPH
Causes of acute urinary retention
Obstruction- BPH, prostate infection, constipation
Pharm - antihistamine, decongestant, anticholinergic, narcotic
Inflammatory
Neurogenic- spinal cord trauma, tumor, MS
Sx of acute urinary retention
• Abdominal distension • Bladder US shows distention • Large amount urine post catheter placement- Post Void Residual(PVR) • BMP- +/- renal failure • UA- +/- infection
Normal bladder volume
<50-100 mL
Initial management for urinary retention
urethral cath
Suprapubic cath (SPC)
CBI (continuous bladder irrigation) – if blood clots
Late management for acute urinary retention
Treat underlying cuase
Tx of acute urinary retention
monitor for 2-4 hrs post decompression
May develop post obstructive diuresis
D/c pt w/ drainage bag and f/u 3-5 days w/ urology
Most common cause of cystitis
E.coli
kelbsiella, proteus miarbilis, pseudomonas, enterococci
Sx of UTI
- Dysuria
- Frequency
- Urgency
- Suprapubic or abdominal pain
- Dark urine- hematuria-dehydration
- No Vaginitis or Cervicitis = likelihood 90% of UTI
- Cloudy urine= likelihood 96% of UTI
Dx of UTI
CLINICAL!!!
U/a & Culture
When is U/A needed
s/sx not clear or:
- back pain, looks sick, male, age ranges
- immunocompromised
- hx of multi courses abx
- hx antibiotic resistance
- hx of multi drug allergies
Lab results for UTI
100,000 CFU/ml (culture not routine)
POS leukocyte esterase and nitrites
Pyuria >= 10 WBC/hpf
Microscopic >10 wbc/hpf
