#PROSTATE VOLUME CALCULATOR SERIES#
In subset analysis of a retrospective series of patients, however, this strategy was not shown to improve outcomes. The use of neoadjuvant androgen ablation has not been prospectively evaluated in the context of cryotherapy. 25 Androgen ablation may also reduce the tumor burden in patients with stage T3 disease (gross extracapsular extension or seminal vesicle involvement). Neoadjuvant androgen ablation using a 3-month depot injection of a luteinizing hormone–releasing hormone agonist usually reduces the prostate to 60% to 70% of its original size. Katsuto Shinohara MD, in Complications of Urologic Surgery (Fourth Edition), 2010 Neoadjuvant Hormone TherapyĪ large prostate volume (>50 cc) can limit the technical feasibility of complete cryoablation. This calculation is similar to measuring the area under the bars in the sample distribution ≥65 ml and dividing by the area under all the bars, yielding the 9.3%. This probability would be represented as the area under the probability distribution ≥65 ml divided by the total area. We could then find the probability that any randomly chosen older male in America shows indications of BPH. If we could measure the prostate volume of every older man in the USA, we would be able to find the relative frequency distribution for the population, which would be the probability distribution. We want to know what proportion of the population is suspect for BPH. However, we are less interested in the characteristics of the sample of older male patients at our hospital than of the population of older male patients in the USA. If r patients out of n show a certain characteristic, r/n is the relative frequency of that characteristic. This is the relative frequency of BPH suspects in our sample. From our sample of 301 prostate patients, 28 readings equal or exceed 65 ml the proportion 28/301=0.093 shows evidence of BPH. Suppose a prostate volume ≥65 ml is taken as suggestive of benign prostatic hypertrophy (BPH). Riffenburgh, in Statistics in Medicine (Third Edition), 2012 The Relationship
