Hello ,

Thanks for your query.

Based on the facts and ultrasound scanning report that you have posted it appears that you have What is called as "Bladder Neck Obstruction (Stenosis)". During micturition because of obstruction your bladder neck does not open completely resulting into incomplete emptying of Bladder. Thus 67 cc of urine remains within the bladder after passing urine (Post Void Residue).

The drug Urimax that has been prescribed by your doctor is a group of drug that selectively relaxes the bladder neck muscles resulting into complete emptying of the bladder.

During ejaculation bladder neck is closed completely to prevent semen from going into the bladder resulting into forward entry of the semen in Urethra. However as after taking this drug, bladder neck remains relaxed and open; therefore semen enters into the bladder - Retrograde Ejaculation.

Retrograde ejaculation is common with Urimax, but since this is only group of drug available to relax the bladder neck you are bound to face this problem. You can try other medication of the same group having highly selective and similar action with minimal side effects like Naphtopedil starting with small dose. I hope Naphtopedil will help you. Please consult your family Physician for dosage and to get prescription of this drug.

Hope I have answered your query. Please feel free to ask if you have any more questions I shall be happy to help you.

With Regards,
