- Abdominal mass
- Cystocele (women)
- Distended bladder
- Enlarged prostate (men)
Tests may include:
- Blood chemistries to reveal kidney damage
- Cystoscopy and retrograde urethrogram (x-ray to look for urethral narrowing)
- Ultrasound to locate the blockage of urine, and find out how well the bladder empties
- Urinalysis to look for blood or infection
- Urine culture to show an infection
- Uroflowmetry to determine how fast the urine flows out
- Urodynamic testing to see how much the urine flow is blocked and how well the bladder contracts
