Commonly Treated Conditions


Rao V. Sunkavally, M.D., F.A.C.S., offers a full range of urology services including the following:

Kidney, bladder, and prostate cancer

Prostate cancer is the most common cancer in men. One out of six men would have prostate cancer in their lifetime. Since the advent of PSA and screening, 90% of prostate cancers are detected in the early localized stage. Early detection is the key to successful treatment and cure. Dr. Sunkavally offers modern diagnostic and therapeutic procedures. Rao Sunkavally, MD, is trained in the latest techniques of surgery for bladder cancer, laparoscopic kidney surgery, Robotic Prostatectomy, Renal and Prostate Cryo-ablation , and Prostate Brachytherapy.

Treatments Provided:

Kidney Stone Disease

Kidney stones can appear suddenly and cause severe pain from obstruction. You should call your doctor if you experience:

  • Extreme pain in your back or side that will not go away
  • Blood in your urine
  • Fever and chills
  • Vomiting
  • Urine that smells bad or looks cloudy
  • A burning feeling when you urinate

Dr. Sunkavally has received specialized training in the latest technologies for removal of kidney stones including the use of laser and Lithotripsy.

Treatments Provided:

Kidney Obstruction

Urine normally drains from the kidney into a tube that carries the urine down to the bladder called the ureter. This area of drainage is referred to as the ureteropelvic junction (UPJ). People can be born with a blockage that progresses later in life or develop a blockage from stones or scar tissue. Eventually this condition can lead to loss of a kidney.

There are many treatments for UPJ Obstruction. The treatments consist of 1/dilating the UPJ, 2/cutting the UPJ with lasers or cautery instruments, or 3/repairing it surgically. The success rates vary from 25% to 95% depending on the form of therapy, with surgical reconstruction giving the best cure rates. Dr. Sunkavally is trained in Robotic Pyeloplasty to repair the blockage. Using the De Vinci Robot, allows for faster recovery from the surgery.

Treatments Provided:

Urinary Incontinence

Urinary incontinence is an accidental loss of urine. Incontinence can be due to several different causes and Dr. Sunkavally is well trained to diagnose the problem in the privacy of his office, easily and painlessly. Most people with incontinence can be successfully treated or cured. Dr. Sunkavally does urodynamic testing in the office to accurately diagnose different types of urinary incontinence. Dr. Sunkavally is trained in the latest minimally invasive out-patient surgeries for the treatment of female stress incontinence, including TVT, TOT (Monarch sling, Mini arc), Prepubic sling and procedures to repair Cystocele or Bladder prolapse. Graft augmentation results in 70% reduction in advanced cystocele recurrence compared to standard repair (colporrhaphy).

Treatments Provided:

Prostate Enlargement

Prostate enlargement is a very common problem that affects older men and can appear gradually, causing frequency and difficulty in urination. Dr. Sunkavally has performed many of the traditional TURP procedures during his 22 years in practice. He has received specialized training in the latest minimally invasive technologies for the treatment of the enlarged prostate, such as:


Impotence is quite common and men are too embarrassed to discuss it. Some 30 million men suffer from ED, but less than 15% of them seek treatment for it. Prevalence of ED increases with age. 52% of men between 40 and 70years of age have ED. It can be successfully treated in most cases.

There are many causes for erectile dysfunction (ED).  The most common diseases associated with this disorder are vascular conditions (ie atherosclesosis – “hardening of the arteries” and abnormal veins inside the penis - so called "venous leak") and diabetes.  Some others include hormone imbalances, neurologic pathology, local penile diseases (ie Peyronie’s disease), smoking, obesity, alcoholism, prostatitis, prostate surgery, certain medications and chronic perineal pressure from overly aggressive bike or horse-back riding.  A variety of emotional disturbances (most commonly depression or performance anxiety) can also cause or be a significant factor in those suffering from ED.  Very commonly, the etiology is multifactoral.  As a result, consultation with a urologist skilled in the evaluation and treatment of ED is recommended.

In addition to a history and physical examination, specialized tests may be indicated to find a cause.  Some of the commonly ordered studies include routine blood tests, hormone levels, and penile duplex color ultrasound.

If a correctible cause is found, specific treatment is instituted.  If the condition is irreversible, most men today can still be restored to normal functionality with the numerous treatments available including oral medications in the class of PDE5 inhibitors  (ie Viagra, Levitra, and Cialis), vacuum erection devices (VEDs), confidence rings (for those with a pure venous leakage), penile injections (ie Edex, Caverject), urethral suppositories (Muse) and penile prosthetic surgery.  

Dr. Sunkavally is trained in all aspects of diagnosis and treatment of impotence. He has the diagnostic equipment for Penile duplex scanning, in order to properly diagnose impotence in the office. He is trained in Penile implant surgery and has done many of them successfully.


About 500,000 men in the U.S. choose vasectomy every year. It is chosen by men who have completed their families or by men who do not want children. These men want birth control that is intended to be permanent. They prefer vasectomy because most reversible methods are less reliable, sometimes inconvenient, and may have unpleasant side effects for the women in their lives. Vasectomy is 98 percent effective. It is intended to be permanent. It is safe. It doesn't limit sexual pleasure.

Dr. Sunkavally offers no-scalpel Vasectomy in his office. With the no-incision, no-scalpel method the skin of the scrotum is not cut. One tiny puncture is made to reach both tubes. The tubes are then tied off, cauterized, or blocked. The tiny puncture heals quickly. No stitches are needed, and no scarring takes place. The no-scalpel method reduces bleeding and decreases the possibility of infection, bruising, and other complications. The procedure takes less than 30 mins.

Vasectomy Reversal

Successful Vasectomy reversals are possible in most cases and Dr. Sunkavally uses microsurgical techniques to do the procedures in an outpatient setting. From 38 to 82 percent of men with reversed vasectomies are able to cause pregnancy. The factors in this wide range include:

  • The length of time since the vasectomy was performed
  • Whether or not antibodies to sperm have developed
  • Age of the woman partner
  • The method used for vasectomy and the length and location of the segments of vas deferens that were removed or blocked.
