Prolieve Transurethral Thermodilatation for Treatment of Symptomatic Benign Prostatic Hyperplasia: 5-Year Results from a Prospective Multicenter Trial.

Prolieve transurethral thermodilatation (TUTD) is the only third-generation transurethral microwave thermotherapy (TUMT) device that incorporates balloon dilation/compression of the prostatic urethra with cooled TUMT, at ≤50 W power. We evaluated its 5-year efficacy in the treatment of symptomatic benign prostatic hyperplasia (BPH) in an open-label prospective multicenter trial. Eligible patients with American Urological Association symptom index score (AUASS) ≥9, peak urine flow rate (Qmax) <12 mL/s, and prostate size 20-80 g without obstructing median lobe were enrolled.

Seasonal changes of fine root density in the Southern Californian chaparral.

Fine root extractions from soil cores of a south facing slope in the Southern Californian chaparral were used to study the dynamics of feeder root growth in a summer-dry area. The studies were concentrated on the root systems of Adenostoma fasciculatum, Arctostaphylos glauca, Ceanothus greggii, and Rhus ovata. The total fine root biomass of Adenostoma fasciculatum increased from 0.

Root systems of chaparral shrubs.

Root systems of chaparral shrubs were excavated from a 70 m plot of a mixed chaparral stand located on a north-facing slope in San Diego County (32°54' N; 900 m above sea level). The main shrub species present were Adenostoma fasciculatum, Arctostaphylos pungens, Ceanothus greggii, Erigonum fasciculatum, and Haplopappus pinifolius. Shrubs were wired into their positions, and the soil was washed out beneath them down to a depth of approximately 60 cm, where impenetrable granite impeded further washing and root growth was severely restricted.
