Laparoscopic Radical Prostatectomy
Laparoscopic radical prostatectomy (LRP) is a form of radical prostatectomy, an operation for prostate cancer. Contrasted with the original open form of the surgery, it does not make a large incision but instead uses fiber optics and miniaturization. The laparoscopic and open forms of radical prostatectomy physically remove the entire prostate and reconstruct the urethra directly to the bladder. Laparoscopic radical prostatectomy and open radical prostatectomy differ in how they access the deep pelvis and generate operative views. In contrast to open radical prostatectomy, the laparoscopic radical prostatectomy makes no use of retractors and does not require that the abdominal wall be parted and stretched for the duration of the operation. __TOC__ Medical uses A few good studies exist looking at open versus laparoscopic versus laparoscopic and robotic radical prostatectomy in cancer as of 2011. There is a robotic and non robotic version. These two versions have unclear differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prostatectomy
Prostatectomy (from the Ancient Greek language, Greek , "prostate" and , "excision") is the surgical removal of all or part of the prostate gland. This operation is done for benignity, benign conditions that cause urinary retention, as well as for prostate cancer and for other cancers of the human pelvis, pelvis. There are two main types of prostatectomies. A simple prostatectomy (also known as a subtotal prostatectomy) involves the removal of only part of the prostate. Surgeons typically carry out simple prostatectomies only for benignity, benign conditions. A radical prostatectomy, the removal of the entire prostate gland, the seminal vesicles and the vas deferens, is performed for cancer. There are multiple ways the operation can be done: with open surgery (via a large incision through the lower abdomen), laparoscopy, laparoscopically with the help of a robotic surgery, robot (a type of minimally invasive surgery), through the urethra or through the perineum.

Male Genital Surgery
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilisation. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. In humans, the word ''male'' can also be used to refer to gender, in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example of convergent evolution. The repeated pattern is sexual reproduction in isogamous species with two or more mating types with gametes of identical form and behavior (but different at the molecular level) to anisogamous species with gamete ...

Surgical Removal Procedures
Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance ( cosmetic surgery), or to remove unwanted tissues (body fat, glands, scars or skin tags) or foreign bodies. The act of performing surgery may be called a surgical procedure or surgical operation, or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments, surgical facility or surgical nurse. Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery. Modern surgical operations typically require a surgica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgical Oncology
Surgical oncology is the branch of surgery applied to oncology; it focuses on the surgical management of tumors, especially cancerous tumors. As one of several modalities in the management of cancer, the specialty of surgical oncology has evolved in steps similar to medical oncology (pharmacotherapy for cancer), which grew out of hematology, and radiation oncology, which grew out of radiology. The Ewing Society—known today as the Society of Surgical Oncology—was started by surgeons interested in promoting the field of oncology. In 2011, the American Board of Surgery ratified Complex General Surgical Oncology via a specialty Board certification. The field was expected to continue expanding via the proliferation of cancer centers, as well as advanced minimally invasive techniques, palliative surgery, and neo-adjuvant treatments. Debate Whether surgical oncology qualifies as a distinct medical specialty remains a topic of heated debate. Today, many agree that it is impractica ...

Impotency
Erectile dysfunction (ED), also referred to as impotence, is a form of sexual dysfunction in males characterized by the persistent or recurring inability to achieve or maintain a penile erection with sufficient rigidity and duration for satisfactory sexual activity. It is the most common sexual problem in males and can cause psychological distress due to its impact on self-image and sexual relationships. The majority of ED cases are attributed to physical risk factors and predictive factors. These factors can be categorized as vascular, neurological, local penile, hormonal, and drug-induced. Notable predictors of ED include aging, cardiovascular disease, diabetes mellitus, high blood pressure, obesity, abnormal lipid levels in the blood, hypogonadism, smoking, depression, and medication use. Approximately 10% of cases are linked to psychosocial factors, encompassing conditions such as depression, stress, and problems within relationships. The term ''erectile dysfunction'' ...

Urinary Incontinence
Urinary incontinence (UI), also known as involuntary urination, is any uncontrolled leakage of urine. It is a common and distressing problem, which may have a significant effect on quality of life. Urinary incontinence is common in older women and has been identified as an important issue in geriatric health care. The term enuresis is often used to refer to urinary incontinence primarily in children, such as nocturnal enuresis (bed wetting). UI is an example of a stigmatized medical condition, which creates barriers to successful management and makes the problem worse. People may be too embarrassed to seek medical help, and attempt to self-manage the symptom in secrecy from others. Pelvic surgery, pregnancy, childbirth, attention deficit disorder (ADHD), and menopause are major risk factors. Urinary incontinence is often a result of an underlying medical condition but is under-reported to medical practitioners. There are four main types of incontinence: * Urge incontinence ...

Lymph Node
A lymph node, or lymph gland, is a kidney-shaped organ of the lymphatic system and the adaptive immune system. A large number of lymph nodes are linked throughout the body by the lymphatic vessels. They are major sites of lymphocytes that include B and T cells. Lymph nodes are important for the proper functioning of the immune system, acting as filters for foreign particles including cancer cells, but have no detoxification function. In the lymphatic system, a lymph node is a secondary lymphoid organ. A lymph node is enclosed in a fibrous capsule and is made up of an outer cortex and an inner medulla. Lymph nodes become inflamed or enlarged in various diseases, which may range from trivial throat infections to life-threatening cancers. The condition of lymph nodes is very important in cancer staging, which decides the treatment to be used and determines the prognosis. Lymphadenopathy refers to glands that are enlarged or swollen. When inflamed or enlarged, lymph nodes can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micrometastasis
A micrometastasis is a small collection of cancer cells that has been shed from the original tumor and spread to another part of the body through the lymphovascular system. Micrometastases are too few in size and quantity to be picked up in a screening or diagnostic test, and therefore cannot be seen with imaging tests such as a mammogram, MRI, ultrasound, PET, or CT scans. These migrant cancer cells may group together to form a second tumor, which is so small that it can only be seen under a microscope. Approximately 90 per cent of people who die from cancer die from metastatic disease, since these cells are so challenging to detect. It is important for these cancer cells to be treated immediately after discovery, in order to prevent the relapse (regrowth of the cancer) and the likely death of the patient. __TOC__ Detection of micrometastatic cells The major concern with micrometastases is that the only way to determine if they are present in distant tissue is to remove cells fr ...

Lymphadenectomy
Lymphadenectomy, or lymph node dissection, is the surgical removal of one or more groups of lymph nodes. It is almost always performed as part of the surgical management of cancer. In a regional lymph node dissection, some of the lymph nodes in the tumor area are removed; in a radical lymph node dissection, most or all of the lymph nodes in the tumor area are removed. Indications Lymphadenectomies are usually done because many types of cancer have a marked tendency to produce lymph node metastasis early in their natural histories. This is particularly true of melanoma, head and neck cancer, differentiated thyroid cancer, breast cancer, lung cancer, gastric cancer, and colorectal cancer. Famed British surgeon Berkeley Moynihan once remarked that "the surgery of cancer is not the surgery of organs; it is the surgery of the lymphatic system." The better-known examples of lymphadenectomy are '' axillary lymph node dissection'' for breast cancer; ''radical neck dissection'' for h ...

Prostate Cancer
Prostate cancer is the neoplasm, uncontrolled growth of cells in the prostate, a gland in the male reproductive system below the bladder. Abnormal growth of the prostate tissue is usually detected through Screening (medicine), screening tests, typically blood tests that check for prostate-specific antigen (PSA) levels. Those with high levels of PSA in their blood are at increased risk for developing prostate cancer. Diagnosis requires a prostate biopsy, biopsy of the prostate. If cancer is present, the pathologist assigns a Gleason score; a higher score represents a more dangerous tumor. Medical imaging is performed to look for cancer that has spread outside the prostate. Based on the Gleason score, PSA levels, and imaging results, a cancer case is assigned a cancer staging, stage 1 to 4. A higher stage signifies a more advanced, more dangerous disease. Most prostate tumors remain small and cause no health problems. These are managed with active surveillance of prostate cancer, ...
