Interstitial cystitis (IC), a type of bladder pain syndrome (BPS), is chronic pain in the bladder and pelvic floor of unknown cause. It is the urologic chronic pelvic pain syndrome of women. Symptoms include feeling the need to urinate right away, needing to urinate often, and pain with sex. IC/BPS is associated with depression and lower quality of life. Many of those affected also have irritable bowel syndrome and fibromyalgia.
The prostate is an 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.
Cystoscopy is endoscopy of the urinary bladder via the urethra. It is carried out with a cystoscope.
Bladder cancer is any of several types of cancer arising from the tissues of the urinary bladder. Symptoms include blood in the urine, pain with urination, and low back pain. It is caused when epithelial cells that line the bladder become malignant.
Prostatectomy is 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.
Tamsulosin, sold under the brand name Flomax among others, is a medication used to treat symptomatic benign prostatic hyperplasia (BPH) and chronic prostatitis and to help with the passage of kidney stones. The evidence for benefit with a kidney stone is better when the stone is larger. Tamsulosin is taken by mouth.
Mitomycin C is a mitomycin that is used as a chemotherapeutic agent by virtue of its antitumour activity.
Oxybutynin, sold under the brand name Ditropan among others, is an anticholinergic medication primarily used to treat overactive bladder. It is widely considered a first-line therapy for overactive bladder due to its well-studied side effect profile, broad applicability, and continued efficacy over long periods of time. It works similar to tolterodine, darifenacin, and solifenacin, although it is usually preferred over these medications. It is sometimes used off-label for treatment of hyperhidrosis, or excessive sweating. It has also been used off-label to treat bedwetting in children, but this use has declined, as it is most likely ineffective in this role. It is taken by mouth or applied to the skin.
Transitional cell carcinoma is a type of cancer that arises from the transitional epithelium, a tissue lining the inner surface of these hollow organs. It typically occurs in the urothelium of the urinary system; in that case, it is also called urothelial carcinoma. It is the most common type of bladder cancer and cancer of the ureter, urethra, and urachus. Symptoms of urothelial carcinoma in the bladder include hematuria. Diagnosis includes urine analysis and imaging of the urinary tract (cystoscopy).
Overactive bladder (OAB) is a common condition where there is a frequent feeling of needing to urinate to a degree that it negatively affects a person's life. The frequent need to urinate may occur during the day, at night, or both. Loss of bladder control may occur with this condition. This condition is also sometimes characterized by a sudden and involuntary contraction of the bladder muscles, in response to excitement or anticipation. This in turn leads to a frequent and urgent need to urinate.
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), previously known as chronic nonbacterial prostatitis, is long-term pelvic pain and lower urinary tract symptoms (LUTS) without evidence of a bacterial infection. It affects about 2–6% of men. Together with IC/BPS, it makes up urologic chronic pelvic pain syndrome (UCPPS).
NMP22 is a tumor marker for bladder cancer. NMP22 is the abbreviated form of Nuclear Matrix Protein Number 22. It reflects the mitotic activity of cells.
Urodynamic testing or urodynamics is a study that assesses how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests can help explain symptoms such as:
Chlornaphazine, a derivative of 2-naphthylamine, is a nitrogen mustard that was developed in the 1950s for the treatment of polycythemia and Hodgkin's disease. However, a high incidence of bladder cancers in patients receiving treatment with chlornaphthazine led to use of the drug being discontinued.
Mark S. Soloway is an American emeritus professor of urology, known for his work on prostate, bladder and kidney cancer. From 1991 to 2010 he was professor and chairman of the University of Miami Miller School of Medicine (MSM) Department of Urology, and subsequently chief of urologic oncology at Memorial Hospital in Hollywood, Florida.
Eosinophilic cystitis is a rare type of interstitial cystitis first reported in 1960 by Edwin Brown. Eosinophilic cystitis has been linked to a number of etiological factors, including allergies, bladder tumors, trauma to the bladder, parasitic infections, and chemotherapy drugs, though the exact cause of the condition is still unknown. The antigen-antibody response is most likely the cause of eosinophilic cystitis. This results in the generation of different immunoglobulins, which activate eosinophils and start the inflammatory process.
Invasive urothelial carcinoma is a type of transitional cell carcinoma. It is a type of cancer that develops in the urinary system: the kidney, urinary bladder, and accessory organs. Transitional cell carcinoma is the most common type of bladder cancer and cancer of the ureter, urethra, renal pelvis, the ureters, the bladder, and parts of the urethra and urachus. It originates from tissue lining the inner surface of these hollow organs - transitional epithelium. The invading tumors can extend from the kidney collecting system to the bladder.
Vibegron, sold under the brand name Gemtesa, is a medication for the treatment of overactive bladder. Vibegron is a selective beta-3 adrenergic receptor agonist.
Intravesical drug delivery is the delivery of medications directly into the bladder by urinary catheter. This method of drug delivery is used to directly target diseases of the bladder such as interstitial cystitis and bladder cancer, but currently faces obstacles such as low drug retention time due to washing out with urine and issues with the low permeability of the bladder wall itself. Due to the advantages of directly targeting the bladder, as well as the effectiveness of permeability enhancers, advances in intravesical drug carriers, and mucoadhesive, intravesical drug delivery is becoming more effective and of increased interest in the medical community.
Nogapendekin alfa inbakicept, sold under the brand name Anktiva, is a fixed-dose combination medication used for the treatment of bladder cancer. It is an interleukin-15 receptor agonist. It is given in combination with Bacillus Calmette-Guérin via intravesical drug delivery. It contains nogapendekin alfa, a human IL-15N72D variant; and inbakicept, an interleukin 15 receptor subunit alpha.
