I am 81 years old. My prostate size was a very large 181 ml and it was cancerous. I also had a diverticula attached to my bladder that was larger than the bladder itself. (Diverticulosis is a condition that occurs when small pouches, or sacs, form and push outward through weak spots in the wall of your colon or bladder.) Fortunately the prostate cancer did not metastasized. Normally, performing a prostatectomy at my age is risky. However, I was otherwise in pretty good health. I decided to have it done with Dr. Dahl. It was the best decision of my life. He did it robotically and his precision was outstanding. The first catheter drainage had very little blood but after that none at all. I cannot find the proper superlatives to use to express my gratitude to Dr. Dahl and has staff.

My husband at the age of 53 had a nerve sparing radical prostatectomy by Dr. Dahl 9 years ago due to cancer. He saved his life and with no side effects from the surgery. I did my research when searching for the best surgeon. Dr Dahls name came up many times as the best. The first surgeon we saw for a consult said he could not do a nerve sparing radical prostatectomy. The cancer was all over the prostatectomy. Dr Dahl went in with an open mind and felt confident he got all the cancer and still was able to save the nerves. I would give Dr Dahl 100 stars if I could.

I am only 3 weeks post surgery, I did all the research on post prostate surgical difficulties, I knew what to expect and was prepared to recover and I knew that recovery would depend on being patient and following doctors orders. I expected urinary incontenence , it didn't happen, I expected ED and I've not had these issues. I can only attribute my good fortune to the brilliance of Dr Dahl. He and his surgical team and all the staff at MGH quite literally took care of me and helped me to understand every aspect of what I could expect being a cancer patient. Dr Dahl's demeanor and his calming influence on me made everything from start to finish during the surgical process much more easy for my wife and myself. I'm a very lucky and so greatful that Dr Dahl has taken me through this process.

Compassionate, professional , empathetic and balanced perspective. Having been diagnosed with early stage Prostate cancer, I was fully expecting to require surgery and was referred to Dr. Dahl who specializes in laporascopic surgical techniques. In short, upon review of my case he felt I was a prime candidate for watchful surveillance and should hold off on surgery if I can deal with knowing I have cancer. Two years later we continue to monitor every six months, have had an additional biopsy, but things remain stable- I truly appreciate his professional approach of not performing surgery if it's not needed, but fully confident that if some day I do, I'm with one of the best in the business.

Dr. Dahl is a brilliant doctor that is vey knowledgeable in urology. I was very fortunate to speak with him and have him diagnose my kidney for possible tumors. He explained to me if they were tumors his surgical procedure would easily abate the situation without removal of a kidney. I have never met such a doctor with confidence about abating cancerous tumors without the necessary chemo or radiation additions. A leader in the field of urology.
