Weight estimation of benign prostatic adenoma with urethral pressure profile

An estimation of the weight of the benign prostatic adenoma by quantitative analysis of the urethral pressure profile has been correlated with the surgically removed specimen in 23 patients. It has been found that the length of the continence zone cane be used as an index of prostatic weight. After operation the length of the continence zone fell into the normal range of the age matched controls.
