The researchers and physicians at the Vattikuti Urology Institute continuously examine our techniques and results. Our research is designed to ensure we are delivering the best care possible to patients.
- Bladder Cancer Risk Calculators
- Kidney Cancer Research: Our surgeons and researchers are pioneers in the development of robotic surgical techniques and approaches for kidney diseases. They publish extensively on the subject.
Two recent publications from the Vattikuti Urology Institute have aroused a great deal of interest among patients and urological surgeons and provide a comprehensive analysis of the Vattikuti Institute Prostatectomy (VIP). We operated on more than 2,700 patients between 2001 and 2006, and collected data on patient #1 through patient #2766. The Cancer study represents the most comprehensive analysis of the largest series of patients undergoing robotic surgery, with the longest follow-up, anywhere in the world.

Results of comprehensive analysis of the Vattikuti Institute Prostatectomy
- How are the patients operated on with the Vattikuti Institute Prostatectomy?
- What about functional effects (beyond a cancer cure)?
- What was the erectile function of the patients?
- Was erectile function better preserved in men who DID HAVE the veil type of nerve sparing developed at the Vattikuti Urology Institute?
- Was erectile function better preserved in men who DID NOT HAVE the veil type of nerve sparing developed at the Vattikuti Urology Institute, but had conventional nerve sparing?
- What was the conclusion of the study?
- How has this research helped advance the Vattikuti Institute Prostatectomy?
We assess urinary function at four months and recommend a procedure to tighten the urinary muscle in patients who are leaking more than one ounce of urine a day.
Was erectile function better preserved in men who DID HAVE the veil type of nerve sparing developed at the Vattikuti Urology Institute?Yes. When we looked at men with normal erectile function who underwent the veil nerve sparing and had a willing partner, 93-97 percent had erections strong enough for intercourse. More than 70 percent of men were back to normal sexual activity, 50 percent without medications and 20 percent with medications such as Viagra, Cialis or Levitra. Another 20-25 percent of men were able to have intercourse even though the strength or frequency of their erection was not the same as before surgery. These men were not taking any medications, mostly because they felt that the medicines did not help.
The veil operation was developed by us based on the belief that some men have nerves hugging the side of the prostate and that the more nerves you preserve, the better erectile function will be. Earlier studies have suggested that this was indeed the case, but these patients were selected carefully. As we became more confident about cancer cure, we started to do the veil nerve-sparing technique more often. As of now, we try to do it in most of our patients with normal erectile function.
Was erectile function better preserved in men who DID NOT HAVE the veil type of nerve sparing developed at the Vattikuti Urology Institute, but had conventional nerve sparing?About three-fourths of the men were able to have sexual intercourse with the help of medications. However, less than 20 percent of men were back to normal function without medication.
Since the conclusion of these studies, we have performed the nerve sparing procedure more frequently. We also introduce medications, injections or the vacuum device in the early post-operative period, while waiting for nerve function to return.
How has this research helped advance the Vattikuti Institute Prostatectomy?
These results were achieved without "coaching" or a structured erectile dysfunction program. Patients were simply asked to take erectile dysfunction medications if they felt they needed it. None of these patients were treated with injections or a vacuum device.
