no prior prostate biopsy: According to one recent study patients with elevated PSA level (>4 ng/mL) could be stratified based on biopsy history, and the following cutoffs can be used:.Prostate-specific antigen (PSA) density in the diagnostic algorithm of prostate cancer. Nordström T, Akre O, Aly M, Grönberg H, Eklund M. Note that while several studies adopted a threshold of 0.15 ng/mL 2recent investigations also found that a threshold of 0.10 and 0.15 ng/mL 2 resulted in the detection of only 77 and 49% of clinically significant prostate cancers respectively.PSA density is defined as the serum PSA level (ng/mL) divided by the volume of the prostate gland (mL), its unit is therefore ng/mL 2.Age-stratified normal values for prostate volume, PSA, maximum urinary flow rate, IPSS, and other LUTS/BPH indicators in the German male community-dwelling population aged 50 years or older. Note that age significantly influences prostate volume with one study of caucasian participants showing a gradual increase of mean prostate volume from 24 to 38 mL between the age groups of 50-54 years and those >75īerges R, Oelke M.Mitterberger M, Horninger W, Aigner F, Pinggera GM, Steppan I, Rehder P, Frauscher F. ultrasound measures of prostate volume and its impact on treatment recommendations for favorable-risk prostate cancer patients: a case series. Murciano-Goroff YR, Wo lfsberger LD, Parekh A, Fennessy FM, Tuncali K, Orio PF 3rd, Niedermayr TR, Suh WW, Devlin PM, Tempany CM, Sugar EH, O’Farrell DA, Steele G, O’Leary M, Buzurovic I, Damato AL, Cormack RA, Fedorov AY, Nguyen PL. The most commonly used threshold for prostatomegaly is >30 mL.The normal prostate measures approximately 3 × 3 × 5 centimeters, and has a volume of about 25 mL.This calculator uses the ellipsoid formula: H × W × L × 0.523 based on the height (H), width (W), and length (L) of the prostate.

The original Tree Density Calculator was written in C++ and ported to PyQGIS in 2018/2019. The Tree Density Calculator is a QGIS plugin and command line interface package designed to calculate tree densitiesīased on brightness images, using the local maximum of a sliding window.
