Before coming to a conclusion certain details are needed. How was your prostate removed, is it cystoscopic removal of prostate, if so what was the biopsy report. Taking for granted the biopsy report was benign growth (as it was removed long back and you were symptoms free till 10 days prior today, we must find out what are all the possible causes of poor stream of urine and difficulty in urination.
