Prostatectomy
Prostatectomy (from the Ancient Greek language, Greek , "prostate" and , "excision") as a medical term refers to 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 ...

Prostate Cancer
Prostate cancer is cancer of the prostate. Prostate cancer is the second most common cancerous tumor worldwide and is the fifth leading cause of cancer-related mortality among men. The prostate is a gland in the male reproductive system that surrounds the urethra just below the bladder. It is located in the hypogastric region of the abdomen. To give an idea of where it is located, the bladder is superior to the prostate gland as shown in the image The rectum is posterior in perspective to the prostate gland and the ischial tuberosity of the pelvic bone is inferior. Only those who have male reproductive organs are able to get prostate cancer. Most prostate cancers are slow growing. Cancerous cells may spread to other areas of the body, particularly the bones and lymph nodes. It may initially cause no symptoms. In later stages, symptoms include pain or difficulty urinating, blood in the urine, or pain in the pelvis or back. Benign prostatic hyperplasia may produce similar symptoms ...

Prostate Removal
The prostate is both an accessory gland of the male reproductive system and a muscle-driven mechanical switch between urination and ejaculation. It is found only in some mammals. It differs between species anatomically, chemically, and physiologically. Anatomically, the prostate is found below the bladder, with the urethra passing through it. It is described in gross anatomy as consisting of lobes and in microanatomy by zone. It is surrounded by an elastic, fibromuscular capsule and contains glandular tissue as well as connective tissue. The prostate glands produce and contain fluid that forms part of semen, the substance emitted during ejaculation as part of the male sexual response. This prostatic fluid is slightly alkaline, milky or white in appearance. The alkalinity of semen helps neutralize the acidity of the vaginal tract, prolonging the lifespan of sperm. The prostatic fluid is expelled in the first part of ejaculate, together with most of the sperm, because of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Artificial Urinary Sphincter
An artificial urinary sphincter (AUS) is an implanted device to treat moderate to severe stress urinary incontinence, most commonly in men. The AUS is designed to supplement the function of the natural urinary sphincter that restricts urine flow out of the bladder. Description There are two types of artificial urinary sphincters: * The artificial urinary sphincter with a balloon reservoir (3-component): cuff, pump and balloon. The cuff is placed around the urethra; the pump is inserted in the scrotum and the balloon reservoir is implanted in the retropubic space – between bladder and iliac vein. The pressure in the hydraulic circuit is generated by the elastic balloon reservoir and from retropubic pressure. * The artificial urinary sphincter with a spring (2-component): cuff and pump unit. The cuff is placed around the urethra and the pump unit is inserted in the scrotum. The pressure in the hydraulic circuit is generated by the spring of the pump unit. The pressure in the ret ...

Transurethral Resection Of The Prostate
Transurethral resection of the prostate (commonly known as a TURP, plural TURPs, and rarely as a transurethral prostatic resection, TUPR) is a urological operation. It is used to treat benign prostatic hyperplasia (BPH). As the name indicates, it is performed by visualising the prostate through the urethra and removing tissue by electrocautery or sharp dissection. It has been the standard treatment for BPH for many years, but recently alternative, minimally invasive techniques have become available. This procedure is done with spinal or general anaesthetic. A triple lumen catheter is inserted through the urethra to irrigate and drain the bladder after the surgical procedure is complete. Outcome is considered excellent for 80–90% of BPH patients. The procedure carries minimal risk for erectile dysfunction, moderate risk for bleeding, and a large risk for retrograde ejaculation. Indications BPH is normally initially treated medically. This is done through alpha antagonists s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robotic Surgery
Robotic surgery are types of surgical procedures that are done using robotic systems. Robotically assisted surgery was developed to try to overcome the limitations of pre-existing minimally-invasive surgical procedures and to enhance the capabilities of surgeons performing open surgery. In the case of robotically assisted minimally-invasive surgery, instead of directly moving the instruments, the surgeon uses one of two methods to administer the instruments. These include using a direct telemanipulator or through computer control. A telemanipulator is a remote manipulator that allows the surgeon to perform the normal movements associated with the surgery. The robotic arms carry out those movements using end-effectors and manipulators to perform the actual surgery. In computer-controlled systems, the surgeon uses a computer to control the robotic arms and its end-effectors, though these systems can also still use telemanipulators for their input. One advantage of using the comput ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 large impact on quality of life. It 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, 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 due to an overactive bladder * Stress incontinence due to "a poorly functioning urethral sph ...

Erectile Dysfunction
Erectile dysfunction (ED), also called impotence, is the type of sexual dysfunction in which the penis fails to become or stay erect during sexual activity. It is the most common sexual problem in men.Cunningham GR, Rosen RC. Overview of male sexual dysfunction. In: UpToDate, Martin KA (Ed), UpToDate, Waltham, MA, 2018. Through its connection to self-image and to problems in sexual relationships, erectile dysfunction can cause psychological harm. In about 80% of cases, physical causes can be identified. These include cardiovascular disease; diabetes mellitus; neurological problems, such as those following prostatectomy; hypogonadism; and drug side effects. About 10% of cases are psychological impotence, caused by thoughts or feelings; here, there is a strong response to placebo treatment. The term ''erectile dysfunction'' is not used for other disorders of erection, such as priapism. Treatment involves addressing the underlying causes, lifestyle modifications, and addres ...

Stress Incontinence
Stress incontinence, also known as stress urinary incontinence (SUI) or effort incontinence is a form of urinary incontinence. It is due to inadequate closure of the bladder outlet by the urethral sphincter. Pathophysiology It is the loss of small amounts of urine associated with coughing, laughing, sneezing, exercising or other movements that increase intra-abdominal pressure and thus increasing the pressure on the bladder. The urethra is normally supported by fascia and muscles of the pelvic floor. If this support is insufficient due to any reason, the urethra would not close properly at times of increased abdominal pressure, allowing urine to pass involuntarily. Most lab results such as urine analysis, cystometry and post-void residual volume are normal. Some sources distinguish between urethral hypermobility and intrinsic sphincter deficiency. The latter is more rare, and requires different surgical approaches. Men Stress incontinence in men is most commonly seen after ...

Pelvic Floor Muscle Training
Kegel exercise, also known as pelvic-floor exercise, involves repeatedly contracting and relaxing the muscles that form part of the pelvic floor, now sometimes colloquially referred to as the "Kegel muscles". The exercise can be performed many times a day, for several minutes at a time but takes one to three months to begin to have an effect. Kegel exercises aim to strengthen the pelvic floor muscles. These muscles have many functions within the human body. In women, they are responsible for: holding up the bladder, preventing urinary stress incontinence (especially after childbirth), vaginal and uterine prolapse. In men, these muscles are responsible for: urinary continence, fecal continence, and ejaculation. Several tools exist to help with these exercises, although various studies debate the relative effectiveness of different tools versus traditional exercises. The American gynecologist Arnold Kegel first published a description of such exercises in 1948. Mechanism of acti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urethral Bulking Injections
A urethral bulking injection is a gynecological procedure and medical treatment used to treat involuntary leakage of urine: urinary incontinence in women. Injectional materials are used to control stress incontinence. Bulking agents are injected into the mucosa surrounding the bladder neck and proximal urethra. This reduces the diameter of the urethra and creates resistance to urine leakage. After the procedure, the pressure forcing the urine from the bladder through the urethra is resisted by the addition of the bulking agent in the tissue surrounding the proximal urethra. Most of the time this procedure prevents urinary stress incontinence in women. Uses A urethral bulking injection is one type of treatment for incontinence in women. Urethral bulking injections are considered by a clinician when the woman has urinary sphincter dysfunction, urethral hypermobility, persistent stress urinary incontinence after a urethral sling A urethral sling is a device that is surgically implant ...
