chemotherapy: A cancer treatment that seeks to kill malignant cells or to prevent them from spreading by use of chemicals introduced into the body.
cholesterol: A fatty steroid that is critical for a number of processes within the body. Cholesterol, in very large amounts, can form deposits within the arteries that can restrict the normal flow of blood.
cholinergic: Referring to the fibers of the parasympathetic nervous system which produce the important neurotransmitter, acetylcholine.
chordee: The condition in which a penis, when erect, exhibits an abnormal downward bend.
chromosome: The rod-shaped structures, present within the nucleus of a cell, which are comprised of DNA and proteins. The chromosomes carry the genes which determine the characteristics of the organism.

chronic bacterial prostatitis: An unusual type of bacterial prostatitis in which there are recurrent infections.
chronic inflammatory bowel syndrome: A long-term disease arising from the large intestine contracting irregularly.
chronic non-bacterial prostatitis: Inflammation of the prostate that is not caused by a bacterial infection.
chronic prostatitis: Slow and long lasting inflammation of the prostate.
chronic renal failure: A slow progression of diminishing kidney function which can ultimately lead to end-stage renal failure, requiring dialysis and/or a kidney transplant.
CIC: See clean intermittent catherization.
circumcision: The practice of surgically removing the foreskin of the penis.
CIS: See carcinoma in situ.
citrate: A salt derived from citric acid.
clean intermittent catheterization: Periodic catheterization, using a clean catheter and sterile procedure, for the purposes of allowing urine to drain from the bladder. Also referred to as CIC.
clear cell sarcoma: An unusual type of tumor in the kidney.
clinical trials: Refers to studies conducted by researches to determine the medical potential of new drugs, equipment or procedures.
clitoris: The small erectile sex organ of the female, located at the front of the vagina.
CMG: See cystometrogram.
cognitive: Referring to the process of conscious thought.
collagen: Protein essential to the formation and maintenance of cartilage, bone and other tissues. Stress urinary incontinence is often treated by means of collagen injection.
collagenase: The enzyme that breaks down collagen.
colon: Section of the large intestine that serves to remove water from digested food.
colonic diverticula: A herniated wall of the colon.
colostomy: A surgical opening in the abdomen used for removing solid waste from the body in lieu of the anus.
comorbidity: The presence several coexisting diseases.
compensatory hypertrophy: Growth by one organ in an attempt by the body to make up for the loss of a different organ.
complete blood count: The standard scale for measuring content of white and red blood cells. Also referred to as a CBC.
compliance: When used in reference to the bladder, a term to express the capacity of the bladder to expand to hold urine.
computerized axial tomography: A diagnostic procedure that utilizes X-rays to create a composite cross-sectional image of a body part that is much more detailed than a singular X-ray alone. Also referred to as a CAT scan.
concealed penis: See buried penis.
condom catheter: A device used to treat men with urinary incontinence. The device is attached over the shaft of the penis and directs urine that is involuntarily released from the bladder and through the urethra into a receptacle.
condoms: Snug fit coverings designed to enclose the erect penis of a male during copulation so as to prevent impregnating the female and/or transmitting a disease.

congenital adrenal hyperplasia: A congenital disorder that causes a deficiency of the cortisol and aldosterone hormones, as well as an excess of the androgen hormone. Also referred to as CAH.

constipation: A condition in which it is difficult to eliminate feces from the body. Caused by the excessive dehydration of stool.
constricted: Made narrower.
continence: The ability to voluntary control urination and bowel movements.
continous cyclic peritoneal dialysis: A type of machine facilitated peritoneal dialysis. Dialysate is drained from and filled to the abdomen by mechanical process. The bulk of dialysis is done while the patient is sleeping, where it is usual to perform 3 to 5 cycles during one dialysis sitting. This is followed by a single cycle during the day. Also referred to as CCPD.
continuous ambulatory peritoneal dialysis: A type of peritoneal dialysis that does not require the use of a machine. This is a continuous (constantly going) form of dialysis that is controlled and monitored by human action. Also referred to as CAPD.

cortex: An organ’s external layer.
