Urethral catheterization
Pass 14-18F Foley catheter (larger if blood clots)
Rate of decompression: rapid complete drainage
At one time, rapid complete bladder decompression was thought to increase the rate of potential complications, however partial drainage and clamping does not reduce these complications and may increase risk for UTI
If unable to pass Foley, consider:
Coude catheter
Suprapubic catheterization

Coude catheter
Suprapubic catheterization
Blood clot
Use 20-24F triple-lumen catheter to irrigate bladder until clear
Consider α-blocker as outpatient if concern for BPH (e.g. tamsulosin 0.4mg QHS)
Results in significant increase in voiding success
Possibility of orthostatic hypotension
Urology consult
Consider for precipitated<unk>  (e.g. stricture, prostatitis, cancer) or need for suprapubic catheterization

Acute urinary retention
Obstructive causes
Acute cystitis
