What Dr. Bui’s patients have to say

LB’s review:

This is a long-overdue letter of praise for Dr.  Matthew Bui. Late in May of 2023, I was diagnosed by Dr. Bui with something no one wants to hear: prostate cancer.  As you can imagine, the diagnosis sent shock waves not only through my system but my family’s as well.

While no one wants to hear the “C” word, Dr. Bui’s calm, professional, and easy-to-understand manner made devastating news much more bearable.  Dr. Bui arranged a Zoom call not only for me but also for my wife and two sons.

The surgery took twice as long as expected due to unforeseen scar tissue from two previous hernia surgeries, but Dr. Bui’s expert skills as a surgeon produced an excellent outcome. 

Dr. Bui came highly recommended to me by my Family Physician as well as several other men who have been treated by Dr. Bui.  I am grateful to be one of the patients who can attest to Dr. Bui’s skill as a surgeon as well as his perfectly pitched bedside manner.

Dr. Bui’s expert skills as a surgeon produced an excellent outcome.

MP’s review:

We have no words to thank you for your humanity, your excellence, and your incredible empathy since the first day of my husband’s appointment.

You were clear, methodical, and with excellent communication as you delivered to us the information on the intensity of the operation my husband needed.

You were a hero for us for getting us the room and the possibility for him to be operated on December 19th, 2019. I know that was not easy at all.

You personally understood what was needed to save my husband and to do all you could for his survival. I know you went beyond what is normal to get that room with us. Thank you so much.

You were so kind and outstanding in how you came to our room on Christmas day and gave us the good news. For us, that was a miracle. And it was a miracle that you made happen with your endless hours in your life, that you have trained to be such an expert.

Rarely in life does one get to encounter such brilliancy of a human being as you. We have met many doctors in the world, and we feel lucky and grateful for that. In you we found another type of doctor;

  • Incredible humanity and excellence as a surgeon.
  • Incredible and unique communication skills of a very difficult reality and danger of an aggressive cancer.
  • A superb empathy beyond what we have ever seen. A vocabulary and accuracy in every word you told us and every thought you transmitted to us.

Your ability to plan and execute an incredible process of healing for my husband was extraordinary.

The operation was a success. We always knew in our hearts and minds that he was in the best possible hands in the world during that very long operation. As he recovers from this major operation and change of life forever for him, we know that you did the best it was possible for him, given his cancer.

It is difficult for him to have the bladder as he has it right now, and I remind him continuously how lucky he is to be able to be free of cancer, as you told us.

As a family, we rejoice in the results of your hard work. Your attention and communication with us. Your excellence in all you have done for us. Thank you very, very, very much .

We are preparing for the wedding with a huge enthusiasm, and we could not be happier with the chance we have in life to marry our only daughter and have him with us.

We will forever be grateful to you.

We are so lucky to be the beneficiaries of the incredible career you have taken on your life. That one of healing patients.

The meaning in your life to save and cure humans is really really deep. The science of your expertise is impressive.

Thank YOU!!!

Rarely in life does one get to encounter such brilliancy of a human being as you.

JT’s review:

Words cannot even begin to express my gratitude towards Dr. Bui and the incredible care he gave me since I was first diagnosed with prostate cancer. All my Doctors told me he was the best prior to meeting him. His calm demeanor and zen-like approach instill confidence in any patient faced with the knowledge that they have cancer and an imminent surgery.

I met Dr. Bui at his Tower Urology office at Cedars-Sinai Hospital, and was immediately impressed. He was calm, caring, and told me I wouldn’t die from this. In fact, he said I would live several more decades. I even asked him the chances of my dying during the surgery. He said he’d operated on more than 2000 patients and had never lost one.

That was beyond reassuring!  My best option was to have surgery to remove the prostate, because the cancer was self-contained. The other option was radiation treatment. He told me radiation wasn’t as effective. The biggest question mark was that the mass was so close to escaping the prostate and up against my nerves that control my erections. Was it self-contained? Dr. Bui believed it was, but he wouldn’t know for sure until he operated.

The operation took place on May 14th. This was my first major surgery. The nurses got me ready in a pre op room. I met Dr. Bui’s anesthesiologist, who was quite pleasant and pretty funny. Then Dr. Bui popped his head in the room, greeted me, and the last thing I remember was him walking away, and the words to the operating team, “OK, let’s rock and roll!”.

The next second, I was in the recovery room on the phone with my girlfriend and brother. The surgery took four and a half hours. It was like ten seconds in my mind. I was told when wheeled into the operating room in anesthesia la la land that I was impressed with the Da Vinci precision robot he controlled performing the surgery.

Recovery was remarkably pain-free. My incisions were so small. I was only in the hospital one night. A week afterwards, Dr. Bui had me back in his office announcing, “You had the best possible result. You’re cancer-free, and we spared your nerves! Now go celebrate!”

Additionally, I heard stories of some people getting prostate removal surgery from other doctors who had to wear adult diapers for months due to urine leakage. I didn’t have to wear them even one day. I’m now 18 days beyond my surgery and walking more than seven miles a day. I return to work tomorrow full of energy, feeling surprisingly, for the most part, back to normal!

Thank you, Dr. Bui, for taking care of me and for a wonderful surgery! I can’t even begin to express the gratitude I feel towards you for saving my life! This entire experience has changed me for the better. …Enjoy living, every precious moment.

I can’t even begin to express the gratitude I feel towards you for saving my life!

DD’s review:

My prostate story began when my primary care physician told me that the manual examination of my prostate didn’t feel quite right. We decided to monitor my PSA scores for a few months. When the PSA jumped from the mid-3s to 4.1, we scheduled a biopsy, which revealed extensive carcinoma and a Gleason score of 6.

Several doctors told me that I could wait and see what happens, but I didn’t see any advantage in waiting—I wanted the cancer out of my body. I did research on the treatment options and on the doctors available to treat me. Dr. Matthew Bui was at the top of the list in a ProPublica study that tracked complication rates among California patients who had undergone radical prostatectomy, so I gave him a call.

Dr. Bui and the staff at Tower Urology could not have been more accommodating or pleasant to deal with. I quickly had an appointment to see him, and when we met, he was reassuring, patient, and extremely clear in his explanations about my condition and about the advantages of the Da Vinci robotic system for resolving it.

He also described the alternative treatments that are available in a very even-handed and informative manner. I felt confirmed in my inclination to select surgery rather than radiation treatment, since radiation can be used following surgery if necessary, but surgery would no longer be an option following radiation. We set the appointment for my surgery during that first visit.

My experience following surgery was much better than I expected. I had very little pain—in fact, while I was in recovery, the nurses repeatedly asked for my pain level on a scale of 1 – 10. They didn’t like it when I said I was basically pain-free, so I started telling them it was a “2.” I spent one night at Cedars-Sinai and went home the next day. The catheter was an annoyance, but I found it easy to manage, and it didn’t hurt when they removed it a week later.

As Dr. Bui predicted, I experienced some incontinence in the weeks after the catheter was removed, but as healing progressed and as I did my Kegel exercises, things got back to normal, and within six weeks, I no longer had any worries about having an accident, daytime or nighttime.

I’m now nine months out from surgery and have had several follow-up appointments with Dr. Bui. My second post-surgery PSA test came back as “undetectable,” and I felt that Dr. Bui rejoiced in that news just as much as my wife and I did. With support from Cialis, my sexual functioning is completely natural and satisfying, which I credit to Dr. Bui’s remarkable skill.

I am deeply grateful to Dr. Bui and the entire team at Tower Urology and Cedars-Sinai for the expert, sensitive care I received and continue to benefit from. I simply cannot imagine how they might have done a better job.

I have been suffering from Testicular pain for the past 3.2 years, and it has been a challenging journey. If I do certain activities like long walks, lifting weights and sex triggers or worsen my testicular pain. The pain was intense enough to significantly impact my daily activities. Pain forces me to rest for 1 to 2 days and applying the Ice packs frequently. I finally met Dr. Justin Houman, who has truly been my life saver. I recently underwent Microsurgical Spermatic Cord Denervation and Varicocelectomies Surgery with Dr. Justice Houman and I noticed a significant reduction in my chronic testicular pain, which has greatly improved my quality of life. I have gradually resumed activities like long walks, lifting weights, sexual activity and I am experiencing only very minimal testicular pain, which doesn’t affect my daily activities. I would highly recommend Dr. Justice Houman to anyone suffering from chronic testicular pain, he is a true expert in men’s andrology. Dr. Houman is truly a life saver for me, Thank you very much Dr. Houman!

Dr.Josephson was an Answer to many prayers! I recently had surgery in Bakersfield with urologist who is past his prime. I couldn't get help after my TURP surgery. For 3 months (90 days) I was in great discomfort, unable to urinate without extreme pain. 40 times a day,wanting to cry ! My Bakersfield urologist said there was NOTHING he could do to help me. A friend sent me to Dr. Josephine. I prayed for a miracle and Dr. Josephson kindly obliged. No further surgery was needed! Dr.Josephson took the "time" to examine me and found the issue immediately and I left his office as happy a child !! Thank you,Dr.Josephson, words cannot express my gratitude enough!! You helped me greatly in my time of need! You were kind and gentle and made me feel cared for. Thank you,May God Bless You !! JSM

A family member was struggling with testicular pain for years and had concerns about fertility. I am so grateful that we were referred to Dr. Houman.

How did a woman with a lifetime of recurrent bladder infections wind up with a urologist whose specialty is male fertility? It happened like this...Dr. Houman was recommended to my husband when he began having the prostate problems that can devastate older men. Dr. Houman solved his urinary difficulties, and I'm convinced, kept him from the fate of a constant catheter. Naturally, I jumped at the chance to be his patient, and have been, for the first time in my life, free for several months of any infections. But the best part of being Dr. Houman's patient is this. When you are in trouble, he will keep in constant touch with you...he does not isolate himself behind a wall of nurses. Naturally, I recommend him highly, Marilyn B.

My experience with Dr. Houman has been nothing but positive. He takes the time to really listen and provide solutions. I came to him, very unsure and very unhappy, with a procedure done by another doctor several years earlier. After a couple of meetings Dr. Houman assured me that he could help me. And that’s exactly what happened. I'm very pleased with the results. His bedside manner and can-do attitude, his insight, enthusiasm and quick email responses were greatly appreciated. You can’t do better than Dr. Houman. I highly recommend him.
