Differential in vivo urodynamic measurement in a single thin catheter based on two optical fiber pressure sensors.

Urodynamic analysis is the predominant method for evaluating dysfunctions in the lower urinary tract. The exam measures the pressure during the filling and voiding process of the bladder and is mainly interested in the contraction of the bladder muscles. The data arising out of these pressure measurements enables the urologist to arrive at a precise diagnosis and prescribe an adequate treatment.

[Impact of preoperative therapy with 5-α-reductase inhibitors in the treatment of benign prostatic hyperplasia].

Benign prostatic hyperplasia is considered a progressive disease intimately linked with aging. The long-term use of combination therapy with a 5-alpha-reductase inhibitor, together with an alpha blocker in men with moderate-severe symptoms, reduces the risk of clinical progression and BPH-related surgery. It is unclear what the impact is of preoperative therapy with 5-ARI in patients that undergo surgery.
