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.

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, ...

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 r ...

Prostate
The prostate is an male accessory gland, accessory gland of the male reproductive system and a muscle-driven mechanical switch between urination and ejaculation. It is found in all male 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 produces and contains fluid that forms part of semen, the substance emitted during ejaculation as part of the male human sexual response cycle, sexual response. This prostatic fluid is slightly Alkalinity, alkaline, milky or white in appearance. The alkalinity of semen helps neutralize the acidity of the vagina, vaginal tract, prolonging the lifespan of sperm. The prostatic fluid is expelled in the first part of ej ...

Robotic Surgery
Robot-assisted surgery or robotic surgery are any types of surgical procedures that are performed 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 the surgeon directly moving the instruments, the surgeon uses one of two methods to perform dissection, hemostasis and resection, using a direct telemanipulator, or through computer control. * A telemanipulator (e.g. the da Vinci Surgical System) is a system of remotely controlled manipulators that allows the surgeon to operate real-time under stereoscopic vision from a control console separate from the operating table. The robot is docked next to the patient, and robotic arms carry out endoscopy-like maneuvers via end-effectors inserted through specially designed trocars. A surgi ...

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 ...

Catheter
In medicine, a catheter ( ) is a thin tubing (material), tube made from medical grade materials serving a broad range of functions. Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure. Catheters are manufactured for specific applications, such as cardiovascular, urological, gastrointestinal, neurovascular and ophthalmic procedures. The process of inserting a catheter is called ''catheterization''. In most uses, a catheter is a thin, flexible tube (''soft'' catheter) though catheters are available in varying levels of stiffness depending on the application. A catheter left inside the body, either temporarily or permanently, may be referred to as an "indwelling catheter" (for example, a peripherally inserted central catheter). A permanently inserted catheter may be referred to as a "permcath" (originally a trademark). Catheters can be inserted into a body cavity, duct, or vessel, brain, skin or adipose tissue.

Erectile Dysfunction
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 Human penis, 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, Hypertension, high blood pressure, obesity, Dyslipidemia, abnormal lipid levels in the blood, hypogonadism, smoking, Depression (mood), depression, and Adverse drug reactions, medication use. Approximately 10% of cases are linked to psychosocial factors, encompassing conditions such as depressio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Stress incontinence 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The 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 through alpha antagonists such as tams ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
