Normal anatomic relationship between urethral sphincter complex and zones of prostrate in young Chinese males on MRI.

UNLABELLED: Objective In this research, the normal anatomic relationship between urethral sphincter complex and zones of prostrate in young Chinese males has been studied.

METHODS

The sagittal, coronal, and axial T2-weighted non-fat suppressed fast spin-echo images of pelvic cavities of 86 Chinese young males were studied.

RESULT: Urethral sphincter complex threaded through the prostate and divided it into 2 parts: transition zone (TZ), periurethral glands internal to the urethral sphincter and peripheral zone (PZ), central zone (CZ), anterior fibromuscular stroma (AFS) zone external to the urethral sphincter. The length of urethral striated sphincter is 12.26-20.94 mm (mean 16.59 mm) at membranous urethra.

CONCLUSIONS

In this paper, we summarized the normal anatomic relationship between urethral sphincter complex and zones of prostrate in young Chinese males with no urinary control problems.
