The present invention provides systems and methods for the evaluation of the
urethra and periurethral tissues using an MRI coil adapted for insertion into the
male, female or pediatric urethra. The MRI coil may be in electrical communication
with an interface circuit made up of a tuning-matching circuit, a decoupling circuit
and a balun circuit. The interface circuit may also be in electrical communication
with a MRI machine. In certain practices, the present invention provides methods
for the diagnosis and treatment of conditions involving the urethra and periurethral
tissues, including disorders of the female pelvic floor, conditions of the prostate
and anomalies of the pediatric pelvis.
