Urinoma: Definition and Diagnosis
A urinoma is an accumulation of urine in the body outside the urinary tract. In most cases, urinoma is caused by injuries to the kidneys
, ureters, urinary bladder
or urethra. Other causes include sudden urinary retention (most commonly ureteral stones) or after surgery of the urinary tract
. The symptoms are usually initially mild. Later: pain, peritonitis, ileus, abscesses, fever, sepsis or electrolyte disturbances develop. Urinoma presents in ultrasound imaging as an echo-free or hypoechoic fluid accumulation. Further diagnostic procedures are abdominal CT, cystography or urethrography, depending on the fluid localization (Titton et al, 2003). Laboratory analysis of the urinoma fluid shows a significant increase in creatinine
compared to serum levels.
