ABSTRACT:
A minimally invasive bladder pressure and urinary flow measurement apparatus and method, the apparatus including a cuff configured to be removably mounted to the penis of the patient and an inflation system for selectively inflating and rapidly deflating the cuff. A pressure transducer is mounted to a catheter and inserted into the urethra to a position upstream from the cuff. A bead on the catheter helps the cuff hold the catheter in place. A urine collection and measurement system is provided to measure the volume and rate of urine discharged by the patient. The transient response also provides an indication whether a constriction of the urethra is proximal or distal.
