This is detrusor hyper reflexia
- the bladder
still thinks the prostate is present and hence contracts powerfully as it did before the surgery.But the prostate being not there you have to go to urinate frequently.
In simple words , the bladder will take some time to adjust to the new outflow tract.Sometimes it can take 8 weeks to 6 months.
It has to be managed with medications which will relax the bladder during this period.
Detrusitol will help with the symptoms.Along with it you have give it some time without being impatient.
There are other drugs which can be used like vesicare
which can be effective.Oxybutynin
is an old drug which can be used in such cases.
Try not to drink too much water.Avoid coffee, tea and aerated drinks.
If this is also not useful,desmopressin
can be used to decrease the urine
production which will decrease the frequency effectively.But it has a side effect of decreasing the sodium levels of our body.This can be corrected with more salt in the food .
I hope this provides you better options to tackle your problem.
All the best and regards
