circumcision mistakes

Would you please answer one question. Why do urologists/surgeons not MEASURE the erect penis before doing a circumcision ? It is dumb no too. I was circumcised 5 years ago at 41 for phomisis and the surgeon muluated my foreskin with a messed up dorsal slit that left me not able to have sex. I am on my second day of healing from the second circ trying to fix the first problem. I am left with a half circumcision this time and removed almost all the inter-foreskin. It would only make sense to measure. The first urologist examined me from across the room getting ME to try and retract the foreskin. The second urologist (professor at a medical school) spent a total of 3 seconds examaning me for this time. I requested a more comperhensive exam but he said he was the best and did not need to. Again, why not measure, measure, mearsure and cut only once??????
