| polycystic disease of kidneys | A progressive disease characterised by formation of multiple cysts of varying size scattered diffusely throughout both kidney's, resulting in compression and destruction of kidney parenchyma, usually with hypertension, gross haematuria, and uraemia; there are two major types: 1) with onset in infancy or early childhood, usually with autosomal recessive inheritance; 2) with onset in adulthood, with autosomal dominant inheritance. Synonym: polycystic disease of kidneys. (05 Mar 2000) |

| kidneys | The kidneys are a pair of organs located in the right and left side of the abdomen which clear poisons from the blood, regulate acid concentration and maintain water balance in the body by excreting urine. The urine then passes through connecting tubes called ureters into the bladder. The bladder stores the urine until it is released during urination. (12 Dec 1998) |
| polycystic kidney disease | <disease> A rare inherited condition in which the kidney are composed of multiple cysts. Kidney cysts are associated with an increased incidence of cerebral aneurysm. Symptoms usually appear later (if they do at all) and include blood in the urine, flank pain, excessive urination at night and abdominal pain. Individuals may also have elevated blood pressure. Chronic (end-stage renal disease) renal failure is the most common result in the 5th to 6th decades of life. Incidence: 1 in 5,000. (02 Jan 1998) |
| polycystic liver disease | Gradual cystic dilation of intralobular bile ducts (Meyenburg's complexes) that fail to involute in embryologic development of the liver; frequently associated with bilateral congenital polycystic kidneys and occasionally with cystic involvement of the pancreas, lungs, and other organs. Synonym: polycystic liver disease. (05 Mar 2000) |
| polycystic ovarian disease | <disease> A condition found among women who do not ovulate, characterised by multiple ovarian cysts and increased androgen production. (09 Oct 1997) |
| disease, ovarian, polycystic | See Disease, polycystic ovarian. (12 Dec 1998) |
| disease, polycystic kidney | Genetic (inherited) disorders characterised by the development of innumerable cysts in the kidneys filled with fluid that replace much of the mass of the kidneys and reduce kidney function leading to kidney failure. (12 Dec 1998) |
| disease, polycystic ovarian | An hormonal problem that causes women to have a variety of symptoms including irregular or no periods, acne, obesity and excessive hair growth. Women with PCO are at a higher risk for uterine cancer (endometrial cancer), diabetes, high blood pressure, and heart disease. With proper treatment, risks can be minimised. PCO is also known as Stein-Leventhal syndrome. (12 Dec 1998) |
| polycystic | Composed of many cysts. (05 Mar 2000) |

Synonym: polycystic liver disease. (05 Mar 2000) |
| polycystic ovary | Enlarged cystic ovary's, pearl white in colour, with thickened tunica albuginea, characteristic of the Stein-Leventhal syndrome; clinical features are abnormal menses, obesity, and evidence of masculinization, such as hirsutism. (05 Mar 2000) |
| polycystic ovary syndrome | <syndrome> Clinical symptom complex characterised by oligomenorrhoea or amenorrhoea, anovulation, and regularly associated with bilateral polycystic ovaries. (12 Dec 1998) |
| kidney, polycystic | Kidney whose tissue is displaced by a large number of tightly packed cysts so that cystic volume predominates over the solid parts to a considerable degree. (12 Dec 1998) |
