Hi, Dr. Purushottm Neurgaonkar welcomes you to HCM VIRTUAL CLINIC. I have gone through your question, and I think I have understood your concern. I will suggest you the best possible treatment options.
1 ) First of all do not panic.
2 ) please get correct medical description of what you are saying about - weak
urinary bladder, from the doctor who has diagnosed this problem.
3 ) In my opinion, it can be some laxity of vaginal wall that occurs after
vaginal delivery. It is usually called as Cystocoele.
It is not a life threatening condition, but needs surgical correction.
After that, she can get pregnant and may be she will be suggested to have delivery by C - section.
4 ) It won't be wrong on my side , to suggest you to get counselled about safe and protected sex activity, and use of suitable
contraceptive method. This will help to have
pregnancy by choice and not by chance.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar.
