Objective:
To analyze the utility of transvesical ultrasound in the estimation of prostate weight.
Methods:
A study was conducted on 50 patients with symptomatic prostatism, aged 54-82 years (mean 60). All the patients had a prostate volume estimation by ultrasound 15 days before surgery using the following formulas: AP x T x Cc x 0.52 cm; AP + T + Cc + 3 mm. All patients underwent surgery for benign obstructive prostatic disease; 25 by TURP and 25 by open surgery. The prostate tissue removed was compared with the US estimation.
Results:
AP x T x Cc x 0.52 cm was found to be the most accurate formula for prostates weighing less than 50 gm and AP + T + Cc + 3 mm the most accurate for prostates greater than 50 gm.
Conclusions:
Our results show that not all formulas are applicable to all prostate sizes.
