Urology, also known as genitourinary surgery, is the branch of medicine that focuses on surgical and medical diseases of the urinary-tract system and the reproductive organs. Organs under the domain of urology include the kidneys, adrenal glands, ureters, urinary bladder, urethra, and the male reproductive organs.
The urethra is a tube that connects the mammalian urinary bladder to the urinary meatus. Male and female placental mammals release urine through the urethra during urination, but males also release semen through the urethra during ejaculation.
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. 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.
A urethral stricture is a narrowing of the urethra, the tube connected to the bladder that allows the passing of urine. The narrowing reduces the flow of urine and makes it more difficult or even painful to empty the bladder.
Hypospadias is a common variation in fetal development of the penis in which the urethra does not open from its usual location on the head of the penis. It is the second-most common birth defect of the male reproductive system, affecting about one of every 250 males at birth. Roughly 90% of cases are the less serious distal hypospadias, in which the urethral opening is on or near the head of the penis (glans). The remainder have proximal hypospadias, in which the meatus is all the way back on the shaft of the penis, near or within the scrotum. Shiny tissue that typically forms the urethra instead extends from the meatus to the tip of the glans; this tissue is called the urethral plate.
Gender-affirming surgery for male-to-female transgender women or transfeminine non-binary people describes a variety of surgical procedures that alter the body to provide physical traits more comfortable and affirming to an individual's gender identity and overall functioning.
Vaginoplasty is any surgical procedure that results in the construction or reconstruction of the vagina. It is a type of genitoplasty. Pelvic organ prolapse is often treated with one or more surgeries to repair the vagina. Sometimes a vaginoplasty is needed following the treatment or removal of malignant growths or abscesses to restore a normal vaginal structure and function. Surgery to the vagina is done to correct congenital defects to the vagina, urethra and rectum. It may correct protrusion of the urinary bladder into the vagina (cystocele) and protrusion of the rectum (rectocele) into the vagina. Often, a vaginoplasty is performed to repair the vagina and its attached structures due to trauma or injury.
Bladder exstrophy is a congenital anomaly that exists along the spectrum of the exstrophy-epispadias complex, and most notably involves protrusion of the urinary bladder through a defect in the abdominal wall. Its presentation is variable, often including abnormalities of the bony pelvis, pelvic floor, and genitalia. The underlying embryologic mechanism leading to bladder exstrophy is unknown, though it is thought to be in part due to failed reinforcement of the cloacal membrane by underlying mesoderm. Exstrophy means the inversion of a hollow organ.
Radical retropubic prostatectomy is a surgical procedure in which the prostate gland is removed through an incision in the abdomen. It is most often used to treat individuals who have early prostate cancer. Radical retropubic prostatectomy can be performed under general, spinal, or epidural anesthesia and requires blood transfusion less than one-fifth of the time. Radical retropubic prostatectomy is associated with complications such as urinary incontinence and impotence, but these outcomes are related to a combination of individual patient anatomy, surgical technique, and the experience and skill of the surgeon.
Vaginectomy is a surgery to remove all or part of the vagina. It is one form of treatment for individuals with vaginal cancer or rectal cancer that is used to remove tissue with cancerous cells. It can also be used in gender-affirming surgery. Some people born with a vagina who identify as trans men or as nonbinary may choose vaginectomy in conjunction with other surgeries to make the clitoris more penis-like (metoidioplasty), construct of a full-size penis (phalloplasty), or create a relatively smooth, featureless genital area.
A urethrotomy is an operation which involves incision of the urethra, especially for relief of a stricture. It is most often performed in the outpatient setting, with the patient (usually) being discharged from the hospital or surgery center within six hours from the procedure's inception.
Urethral cancer is a rare cancer originating from the urethra. The disease has been classified by the TNM staging system and the World Health Organization.
Urethroplasty is the surgical repair of an injury or defect within the walls of the urethra. Trauma, iatrogenic injury and infections are the most common causes of urethral injury/defect requiring repair. Urethroplasty is regarded as the gold standard treatment for urethral strictures and offers better outcomes in terms of recurrence rates than dilatations and urethrotomies. It is probably the only useful modality of treatment for long and complex strictures though recurrence rates are higher for this difficult treatment group.
Urogynecology or urogynaecology is a surgical sub-specialty of urology and gynecology.
Bulbar urethral necrosis is a problem that can occur after a pelvic fracture associated urethral distraction defect (PFUDD).
Jerry G. Blaivas is an American urologist and senior faculty at the Icahn School of Medicine at Mount Sinai in New York City and adjunct professor of Urology at SUNY Downstate Medical School in Brooklyn, as well as professor of clinical urology at College of Physicians and Surgeons, Columbia University and clinical professor of Urology at Weill Medical College of Cornell University. He has four patents pending, has received four research grants for which he served as the principal investigator, and served as a major in the United States Army assigned to the Walson Army Hospital. He additionally served as president for the Urodynamic Society.
If medical treatment is not effective, surgery may need to be performed for benign prostatic hyperplasia.
Miroslav L Djordjevic is a Serbian surgeon specializing in sex reassignment surgery, and an assistant professor of urology at the School of Medicine, University of Belgrade, Serbia.
Richard Anthony Santucci MD, FACS is an American reconstructive urologist who currently lives and works in Austin, Texas.
Kurt McCammon is a Professor and the Devine Chair in Genitourinary Reconstructive Surgery at Eastern Virginia Medical School, where he has served as the Chairman for the Department of Urology since 2011, Program Director of the Department of Urology since 2006, and Fellowship Director for the Adult and Pediatric Genitourinary Reconstructive Surgery since 2010. Additionally, he is the past president of the Society of Genitourinary Reconstructive Surgeons, on the board of the International Volunteers in Urology, and a current member of the American Urological Association Board of Directors. As a reconstructive urologist, McCammon surgically addresses urethral stricture disease, male urinary incontinence, erectile dysfunction, female urinary incontinence, genital abnormalities, and other genitourinary issues.
