Dear friend,
An mcu x ray plate would have been more helpful
However I can see that MCU report states that there is a large PVR -- i.e a lot of urine stay behind after u pee.
This needs to be confirmed by doing a uroflowmetry ( ufr) followed by usg pvr measurement .
If it's confirmed objectively that ur stream is indeed slow ( in ufr) and that u have a large post void residue---- there is only one possibility.. that ur bladder muscles r not working efficiently which may be associated with sphincter dyssynergia.
This can be evaluated on by urodynamic study.
Next Steps
confirm high pvr and evaluate stream pattern by doing a basic report-
uroflowmetry followed by usg pvr
once confirmed ... u will need a urodynamic study !
