As we mentioned in previous articles during the last stage of the menstrual cycle, normally a layer of endometriosis lining in the inside of the uterus is expelled, known as menstruation blood. Instead some of the endometriosis tissues grow somewhere in the body causing endometriosis. They also react to hormonal signals of the monthly menstrual cycle, building up tissue, breaking it, and eliminating it through menstrual period. In this article, we will discuss the relationship between endometrosis and urinary diseases.

1. Irregular urination
Normally irregular urination in adults is caused by pressure of a fetus on the bladder of a pregnant woman or losing muscle of the badder causing the feeling to use the bathroom. In woman with endometriosis, it is caused by endometrial implants or adhesion in the badder region, which increases the pressure to the urinary system resulting in irregular urination.

2. Lower abdominal pain on urination
Lower abdominal pain may be caused by endometrial implants, adhesion or cysts in the pelvic region or by over-production of prostaglandin which increases the tension of muscle spam in the bowel and the uterus. Lower abdominal pain on urination is caused by over-production of prostaglandin which stimulate the contraction of the ovaries and uterus muscles or endometrial implants and adhesion in the lower abdominal area causing pressure and pain on urination.

3. Blood in urine
Blood in urine is a common cause of women with endometrial implants or cysts attached to the bladder area as resulting of bleeding of the endometriosis. It worsens just before and during menstruation.

4. Kidney tenderness
Kidney tenderness may be caused by the weakened immune system of woman with endometrial adhesion attached to the kidney causing abnormal function of the kidney and kidney fluid retention. It may be caused by cysts in the pelvic region which increases pressure of the bladder and urinary tract resulting in mounting pressure to the kidney, causing kidney tenderness. It worsens at the beginning and during period.
