A ureterosigmoidostomy is a surgical procedure where the ureters which carry urine from the kidneys, are diverted into the sigmoid colon. It is done as a treatment for bladder cancer, where the urinary bladder had to be removed. Rarely, the cancer presents in children between the ages of 2 & 10 yrs old as an aggressive rhabdomyosarcoma, although there are diagnoses of children as young as 3 months old. The procedure was also used several decades ago as a correctional procedure for patients born with bladder exstrophy. In the case of some bladder exstrophy patients, occasional bowel incontinence at night is one uncontrollable consequence.
A bladder stone is a stone found in the urinary bladder.
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 in order 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 will 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. Labiaplasty, which alters the appearance of the vulva, can be performed as a discrete surgery, or as a subordinate procedure within a vaginoplasty.
Urinary retention is an inability to completely empty the bladder. Onset can be sudden or gradual. When of sudden onset, symptoms include an inability to urinate and lower abdominal pain. When of gradual onset, symptoms may include loss of bladder control, mild lower abdominal pain, and a weak urine stream. Those with long-term problems are at risk of urinary tract infections.
The Rastelli procedure is an open heart surgical procedure developed by Italian physician and cardiac surgery researcher, Giancarlo Rastelli, in 1967 at the Mayo Clinic, Ajmer and involves using a pulmonary or aortic homograft conduit to relieve pulmonary obstruction in double outlet right ventricle with pulmonary stenosis.
Lithotomy from Greek for "lithos" (stone) and "tomos" (cut), is a surgical method for removal of calculi, stones formed inside certain organs, such as the urinary tract, bladder, and gallbladder (gallstones), that cannot exit naturally through the urinary system or biliary tract. The procedure is usually performed by means of a surgical incision. Lithotomy differs from lithotripsy, where the stones are crushed either by a minimally invasive probe inserted through the exit canal, or by an acoustic pulse, which is a non-invasive procedure. Because of these less invasive procedures, the use of lithotomy has decreased significantly in the modern era.
A cystocele, also known as a prolapsed bladder, is a medical condition in which a woman's bladder bulges into her vagina. Some may have no symptoms. Others may have trouble starting urination, urinary incontinence, or frequent urination. Complications may include recurrent urinary tract infections and urinary retention. Cystocele and a prolapsed urethra often occur together and is called a cystourethrocele. Cystocele can negatively affect quality of life.
Prostatectomy as a medical term refers to the surgical removal of all or part of the prostate gland. This operation is done for benign conditions that cause urinary retention, as well as for prostate cancer and for other cancers of the pelvis.
Pelvic exenteration is a radical surgical treatment that removes all organs from a person's pelvic cavity. It is used to treat certain advanced or recurrent cancers. The urinary bladder, urethra, rectum, and anus are removed. In women, the vagina, cervix, uterus, fallopian tubes, ovaries and, in some cases, the vulva are removed. In men, the prostate is removed. The procedure leaves the person with a permanent colostomy and urinary diversion.
The Mitrofanoff procedure also known as the Mitrofanoff appendicovesicostomy, is a surgical procedure in which the appendix is used to create a conduit, or channel, between the skin surface and the urinary bladder. The small opening on the skin surface, or the stoma, is typically located either in the navel or nearby the navel on the right lower side of the abdomen. Originally developed by Professor Paul Mitrofanoff in 1980, the procedure represents an alternative to urethral catheterization and is sometimes used by people with urethral damage or by those with severe autonomic dysreflexia. An intermittent catheter, or a catheter that is inserted and then removed after use, is typically passed through the channel every 3–4 hours and the urine is drained into a toilet or a bottle. As the bladder fills, rising pressure compresses the channel against the bladder wall, creating a one-way valve that prevents leakage of urine between catheterizations.
An ileal conduit urinary diversion is one of various surgical techniques for urinary diversion. It has sometimes been referred to as the Bricker ileal conduit after its inventor, Eugene M. Bricker. It is a form of incontinent urostomy, and was developed during the 1940s and is still one of the most used techniques for the diversion of urine after a patient has had their bladder removed, due to its low complication rate and high patient satisfaction level. It is usually used in conjunction with radical cystectomy in order to control invasive bladder cancer.
Vesicoureteral reflux (VUR), also known as vesicoureteric reflux, is a condition in which urine flows retrograde, or backward, from the bladder into one or both ureters and then to the renal calyx or kidneys. Urine normally travels in one direction from the kidneys to the bladder via the ureters, with a 1-way valve at the vesicoureteral (ureteral-bladder) junction preventing backflow. The valve is formed by oblique tunneling of the distal ureter through the wall of the bladder, creating a short length of ureter (1–2 cm) that can be compressed as the bladder fills. Reflux occurs if the ureter enters the bladder without sufficient tunneling, i.e., too "end-on".
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.
Urinary diversion is any one of several surgical procedures to reroute urine flow from its normal pathway. It may be necessary for diseased or defective ureters, bladder or urethra, either temporarily or permanently. Some diversions result in a stoma.
Neurogenic bladder dysfunction, or neurogenic bladder, refers to urinary bladder problems due to disease or injury of the central nervous system or peripheral nerves involved in the control of urination. There are multiple types of neurogenic bladder depending on the underlying cause and the symptoms. Symptoms include overactive bladder, urinary urgency, frequency, incontinence or difficulty passing urine. A range of diseases or conditions can cause neurogenic bladder including spinal cord injury, multiple sclerosis, stroke, brain injury, spina bifida, peripheral nerve damage, Parkinson's disease, or other neurodegenerative diseases. Neurogenic bladder can be diagnosed through a history and physical as well as imaging and more specialized testing. Treatment depends on underlying disease as well as symptoms and can be managed with behavioral changes, medications, surgeries, or other procedures. The symptoms of neurogenic bladder, especially incontinence, can have a significant impact on quality of life.
Retropubic space is a potential avascular space located between the pubic symphysis and the urinary bladder. The retropubic space is a preperitoneal space, located behind the transversalis fascia and in front of peritoneum.
The hepatic lymph nodes consist of the following groups:
A Malone antegrade continence enema is a surgical procedure used to create a continent pathway proximal to the anus that facilitates fecal evacuation using enemas.
In urology, the Mitrofanoff principle is the creation of a passageway for urine or enema fluid that, by its (surgical) construction, has a valve mechanism to allow continence.
If medical treatment is not effective, surgery may need to be performed for benign prostatic hyperplasia.
