USING TRANSRECTAL ULTRASONOGRAPHY IN THE ASSESSMENT OF PROSTATE VOLUME IN ADULT MALES IN THE CAPITAL CITY OF IMO STATE, NIGERIA
Keywords:Prostate, Normogram, Male subjects, Volume, Size
Objective: Prostate gland is a compound tubuloalveolar exocrine gland of male reproductive system in human. Morphometric analyses of an organ with the use of radiologic technique have been shown to be imperative in the evaluation of radiologic or systemic disease. The radiologic anatomist has described inaccuracy with physical examination of organs morphometry as it provides misleading results involving a particular organ for prognostic and diagnostic purpose in our region. This work is aimed at establishing the normal prostatic volume in adult males in Imo State, Nigeria. It also dealt on relationship between prostate volumes (PVs) with age.
Methods: The investigation was carried out in adult male between the ages of 21 and 80 years and the research tool used was an ultrasound machine. Subjects were subjected to transrectal scanning as they were lying on this left lateral position. PV was evaluated using the ellipsoidal formula: PV=0.524×L×H×W. A total of 200 individuals were studied.
Results: The result of this study gave a mean of 28.72 ml which tallied closely with similar work on prostate size in adult males in Nigeria with a mean value of 20.93 ml. The prostate size had statistically significant relationship (p<0.05) with the individual age, with male subjects in the age group of 71–80 years showing the highest volume of 36.1±1.81 ml which corresponds with the previous studies done in Nigeria.
Conclusion: A normogram for PV has been established for adult male in Owerri, Imo State, Nigeria, to be 28.72 ml and correlation between the PV and age is significantly positive (p<0.05).
