Thanks for your query.Based on the facts that you have posted it appears that you have undergone open radical prostatectomy
and some of the hemo clips have migrated in to bladder causing problem in passing urine.
This is known complication of migrating hemo clips into bladder .
You have to monitor yourself by doing X-rays very frequently and if found clips to have migrated in bladder take them out with endoscope.
There is no need to do reconstructive surgery
