MonaLisa Touch

Studies show that as many as 50 percent of women suffer from vaginal dryness, itching, and pain, resulting in decreased sexual enjoyment or intimacy avoidance due to embarrassment. Now it’s possible to turn back the hands of time and regain control of your feminine health. MonaLisa Touch is the only laser therapy approved by the FDA to restore women’s pelvic health. It delivers gentle laser energy to the vaginal wall tissue, resulting in the generation of new collagen and elastin and vascularization of the treated area. Treatments typically take five minutes, and only three sessions are needed for full results. Learn More

Pelvic Organ Prolapse

Pelvic organ prolapse refers to the drooping or prolapse of pelvic organs, including the bladder, uterus, vagina, small bowel or rectum. It occurs when the muscles and tissues supporting the organs weaken, sometimes as a result of aging, pregnancy and childbirth, hysterectomy, obesity or chronic cough. Symptoms can include painful intercourse, lower backache, urinary leaking, a chronic urge to urinate or constipation.

Female Urinary and Fecal Incontinence

Stress urinary incontinence occurs when laughing, sneezing and/or coughing causes urine to escape involuntarily from the body. Because this problem is often embarrassing, patients may put off seeking help from their doctors in a timely manner.

Pelvic Floor Dysfunction (Pelvic Pain or Dyspareunia)

Dyspareunia is abnormal pain that occurs during or after intercourse in the lower back or genital/pelvic regions of the body. Causes of dyspareunia can include muscle dysfunction within the vagina, poor lubrication and/or thinning of the vaginal wall, tissue adhesions, nerve irritation, and/or scarring of the perineal region.

Vulvodynia

Pain located around the vulva without an identifiable cause is known as vulvodynia. Vulvodynia is characterized by burning, searing, “knife-like” pain of varying degrees of intensity, with a highly variable description and location of symptoms. Women with this condition often experience extreme pain during sexual intercourse, gynecological exams, difficulties with (or inability to use) tampons and pain while performing certain exercises such as riding bicycles.

Vaginismus

Vaginismus is characterized by an inability to experience complete vaginal penetration due to introital (vaginal opening) tightness resulting from muscle spasm. Vaginismus causes significant pain and discomfort, as well as issues with vaginal penetration such as with sexual intercourse.

Painful Bladder Syndrome/Interstitial Cystitis

Interstitial cystitis is a chronic condition characterized by a combination of uncomfortable bladder pressure, bladder pain and sometimes pain in your pelvis, which can range from mild burning or discomfort to severe pain.

Overactive Bladder, Voiding Dysfunction

Behavioral treatments have been used for several decades to treat urinary incontinence, overactive bladder and other lower urinary tract symptoms. The spectrum of behavioral treatments includes those that target voiding habits and lifestyle, as well as those that train pelvic floor muscles to improve strength and control.

Menopause

Menopause is time in a woman’s life when her periods (menstruation) eventually stop and the body goes through changes that no longer allow her to get pregnant. It is a natural event that normally occurs in women ages 45 – 55

Heavy Menstrual Cycle

All of us, from time to time, experience what we feel is unusually heavy bleeding during our menstrual periods. Fortunately, most often what we think is abnormal uterine bleeding is not excessive enough to be diagnosed as menorrhagia.

InterStim Therapy

InterStim Therapy is a proven neuromodulation therapy that targets the communication problem between the brain and the nerves that control the bladder.

In-Office Hysteroscopy

A hysteroscopy is a test that uses sterile salt water and a tiny telescope to visualize the inside of your uterus. The test is able to detect scar tissue, polyps, fibroids, and any uterine abnormality such as a septate uterus, that may prevent an embryo from implanting properly.

Total Laparoscopic Hysterectomy (TLH)

Laparoscopic hysterectomy utilizes the latest, minimally invasive surgical techniques to remove the uterus through very small abdominal incisions. This procedure is indicated for heavy and irregular menstruation that is unresponsive to medical management, symptomatic fibroids, or pelvic pain from endometriosis.

Laparoscopic Supracervical Hysterectomy (LSH)

The laparoscopic supracervical hysterectomy is a procedure where tissue is removed from the body through a tiny incision of about 14 millimeters. The procedure does not require the surgeon to suture, and with no stitches required, the healing process for the patient is often easier. Patients seldom need pain medication after the laparoscopic supracervical hysterectomy because the procedure is so simple.

Laparoscopic Oophorectomy / Ovarian Cystectomy

Oophorectomy is the laparoscopic removal of the ovaries, the almond-shaped organs, on each side of your uterus. Ovaries contain eggs and secrete the hormones that control your reproductive cycle. Removing the ovaries greatly reduces the amount of estrogen and progesterone hormones circulating in your body. This can halt or slow breast cancers that need these hormones to grow.

Ovarian cystectomy removes only the cysts on the ovaries if the cysts are not cancerous, leaving the ovaries intact.

Laparoscopic Laser Surgery for Endometriosis

Laparoscopy is the most common procedure used to diagnose and treat mild to moderate endometriosis, requiring minimally invasive surgery and typically performed while the patient is under general anesthesia. Any visible endometriosis implants and scar tissue that may be causing pain or infertility are likely to be removed.

The procedure is usually done at an outpatient facility, although the surgery occasionally requires a hospital stay of a day. Patients are able return to their normal activities in one to two weeks. In comparison to open abdominal surgery, laparoscopic surgery results in less tissue trauma and scarring, smaller incisions, and can be performed on an outpatient basis with a shorter recovery time.

Bladder Support Surgery (Sling)

Without post-op catheterization, bladder suspension surgery is a procedure used to treat urine leakage that occurs when a person sneezes, laughs or coughs — a condition called stress incontinence. Childbirth, as well as hormonal changes such as those brought on by menopause, can cause a woman to lose muscle tone along the pelvic floor. This can lead to stress incontinence and a need for bladder suspension surgery.

Pelvic Support Surgery (Correction of Cystocele/Rectocele)

Prolapse is an all-inclusive term, referring to a protrusion through the vagina that creates an uncomfortable feeling, pressure or pain. In addition to protrusion and pressure symptoms, rectocele may cause difficulty with bowel movement, while cystocele may result in difficulty urinating.

Laparoscopic surgery uses tiny incisions to correct prolapse, resulting in minimal pain and discomfort. It can be performed on an outpatient basis, decreasing the length of recovery time.

Alternatives to Hysterectomy

Hysteroscopic endometrial ablation is a highly-effective, alternate procedure to a hysterectomy, and is used to control heavy, prolonged menstrual bleeding when other treatment options have not been effective. The procedure involves use of a laser beam or other heat source, electricity or freezing while the patient is under local or general anesthesia.

Endometrial ablation is typically done on an outpatient basis, with a recovery time of a few days to two weeks. Younger women are less likely than older women to respond to endometrial ablation, and are more likely to continue to have periods and/or need a repeat procedure

Essure (In-Office) Tubal Ligation

Essure tubal ligation is an alternative method of birth control to tubal ligation, with faster recovery time and fewer risks and side effects. The procedure is less invasive than tubal ligation, involving no incisions, punctures, burning or tying

Typically, only local anesthesia is required so that a soft, flexible micro-insert can be placed into each fallopian tube. The procedure can be performed in-office and in under an hour. Patients are able to quickly resume their regular schedules and normal sexual activity.
