Personal information


Dr Claudius Fridrich is a specialist in endometriosis and head physician at the gynecological department of the Heilig Geist Hospital in Cologne.

The specialized team of the Endometriosis Center at the gynecological department of the Heilig Geist Hospital in Cologne has all recommended therapeutic procedures for the treatment of endometriosis available. The patient's wishes are discussed in advance, and necessary treatment is always carried out as gently as possible.

Endometriosis Specialists Cologne: Experts for one of the Most Common Gynecological Diseases in Women

Endometriosis describes benign growths of the endometrium outside the uterus in the abdomen. These can develop on the ovaries or at other locations within the abdominal cavity, in the vagina, or even in the lungs, muscles, and digestive tract. The disease often occurs in women in their childbearing years and can cause severe menstrual cramps, pain during sexual intercourse and bowel movements, or even infertility.

The renowned team of experts at the gynecological department masters the entire spectrum of diagnostic procedures and therapies for endometriosis.

Endometriosis Consultation Hour and Diagnosis

The gynecology department at Heilig Geist Hospital in Cologne offers a weekly endometriosis consultation hour to diagnose endometriosis reliably. After a detailed medical history review, the suspected diagnosis is confirmed by ultrasound with high-resolution imaging. In addition, a comprehensive gynecological examination is carried out to rule out other causes of the typical symptoms.

Specialists for Diagnostic Abdominal Endoscopy (Laparoscopy)

A diagnostic laparoscopy (abdominal endoscopy) can confirm the suspected diagnosis of endometriosis. This method involves minimally invasive removal of small tissue samples from the suspicious focal growths. However, this procedure is only performed if there is a reasonable suspicion of endometriosis after previous examinations. Based on the biopsies, the diagnosis is finally confirmed under the microscope.

Excellent Expertise in the Treatment and Therapy of Endometriosis.

If the pathologist confirms endometriosis after a fine tissue examination of the samples taken, the spread of the disease can be effectively contained. Depending on the extent of the findings and the severity of the disease, drug therapy with synthetic sex hormones can be started initially. These progestins cause a reduction in estrogen levels and a degeneration of the endometrium - foci of endometriosis can subside.

In addition, minimally invasive surgery to ablate endometriosis foci is offered and regularly carried out at Heilig Geist Hospital. Targeted measures can alleviate severe menstrual symptoms. In an optimal case, a desire to have children can also be fulfilled.

If there is no longer a desire to have children, surgical removal of the uterus may be advisable to limit the spread of the endometriosis lesions. After the surgery, drug therapy with progestogen hormone preparations is advisable to prevent the foci from flaring up again.

Hysteroscopy in Cologne: Specialists in Hysteroscopy for the Detection of Changes on the Inside of the Uterus

Pathological changes on the inside of the uterus can be easily detected and often treated via hysteroscopy of the organ. The uterine cavity can be viewed with a video endoscope during the hysteroscopy.

Access is gained through the vagina without a skin incision. However, since the cervix is sensitively dilated, general or regional anesthesia is advisable, especially for surgical hysteroscopy, due to the larger diameter of the equipment. To expand it, gas or sterile water is applied to the uterine cavity under local anesthesia.

A flexible tube with a camera and working channels can be advanced into the body through the vaginal canal and into the organ through the cervix. The video images allow real-time evaluation of the endometrial mucosa so that tumors, polyps, malformations, or unclear bleeding can be diagnosed with certainty.

The working channel in the endoscope allows specimen collection and hemostasis under visual monitoring. In addition, polyps and fibroids can be removed in the same setting, and malformations, such as the uterine septum, can be treated directly.

Gynecology Department Cologne: Modern Gynecology and Holistic Consultation

The gynecology department of the Heilig Geist Hospital stands for a holistic approach. Questions concerning life planning and health care are taken into account and considered on an individual basis. In addition to state-of-the-art medicine, the gynecology department also offers complementary medical support services.

Innovative Gynecology: Minimally Invasive and Robot-Assisted Surgeries and Procedures According to the State of the Art in Medical Technology.

The team at the gynecology department is experienced in using the latest minimally invasive surgical methods. Nowadays, most procedures on the female reproductive organs in the abdomen are no longer performed through an unsightly abdominal incision but through small, laparoscopic approaches - hidden in the navel. The entire abdominal cavity can be viewed under camera guidance, and instruments can be brought into the surgical area. Robot-assisted laparoscopy using the DaVinci system can also be considered in exceptional cases.

In this way, numerous surgeries are carried out at the Heilig Geist Hospital for cancerous diseases of the uterus or ovaries. In addition, minimally invasive procedures are also used to remove extensive endometriosis foci and to intervene in the fallopian tubes for sterilization or infertility diagnosis.

Furthermore, the department specializes in the surgical therapy of urinary incontinence and reconstructions of the pelvic floor muscles for uterine prolapse.
