Quanto deve essere il volume di una prostata normale?
Le dimensioni della prostata cambiano in base all'età e alle condizioni ormonali del soggetto. Un uomo di 42 anni, sano, ha un diametro trasversale medio di 4 cm, diametro antero-posteriore di circa 2 cm, e verticalmente è lunga 3 cm. Il peso medio è di 10-20 g nei soggetti normali.
What is the formula to calculate prostate volume?
- Prostate Volume Calculation A simple prorated ellipsoid formula is commonly used to calculate prostate volume: (anterior-posterior diameter) x (transverse diameter) x (superior-inferior diameter) x Π/6 (approximately 0.52) is accurate and reproducible.
What is the normal range of prostate volume in older men?
- In these men aged 50-80 years, mean total prostate volume continuously increased from 24 to 38 cc and mean PSA concentration from 1.1 to 2.5 ng/ml. PSA concentration in men with a prostate volume <25 cc also showed a continuous increase with aging, starting at 0.8 in the youngest and ending at 1.9 ng/ml in the oldest age group.
What does an enlarged prostate look like in a 70 year old?
- The 70 year old male shows an enlarged prostate 7.2cms in A-P by 6.1cms. in the axial plane. The gland is enlarged based on these measurements. Two distinct zones are identified because the gland is abnormal. The posterior zone is canoe shaped is hypodense and represents the peripheral zone.
How much does the prostate gland weigh in a 30 year old?
- A normal prostate gland weighs about 20g-30g in a 30 year old male. The normal volume is between 20-30ccs. The prostate normally measures 3 cm in length (height), 4 cm in width (transverse), and 2 cm in depth (anteroposterior dimension). It remains relatively stable in size until the age of 50 when increasing weight of the gland is observed.
