Thanks for your query.Based on the facts that you have posted it appears that you have undergone TURP twice for BEP. However you have difficulty in passing urine and now on Supra pubic catheterisation to drain your bladder
Please discuss with your Urologist
the possibility of having stricture of urethra
. Get your Retrograde Cysto urethrogram done to rule out stricture formation.
If positive explore the feasibility of doing Urethroplsty to solve the problem permanently.
