Bladder outlet obstruction
BOO; Lower urinary tract obstruction; Prostatism; Urinary retention - BOOBladder outlet obstruction (BOO) is a blockage at the base of the bladder. It reduces or stops the flow of urine into the urethra. The urethra is the tube that carries urine out of the body.

Bladder catheterization - male
Catheterization is accomplished by inserting a catheter (a hollow tube, often with and inflatable balloon tip) into the urinary bladder. This procedure is performed for urinary obstruction, following surgical procedures to the urethra, in unconscious patients (due to surgical anesthesia, coma, or other reasons), or for any other problem in which the bladder needs to be kept empty (decompressed) and urinary flow assured. The balloon holds the catheter in place for a duration of time. Catheterization in males is slightly more difficult and uncomfortable than in females because of the longer urethra.

Bladder biopsy
A bladder biopsy is performed if abnormalities of the bladder are found, or if a tumor is grossly visible. During the biopsy a small portion of tissue is removed and sent to the laboratory for analysis.

The balloon holds the catheter in place for a duration of time.
