Urine.
Urine is produced by the kidneys, which filter waste and excess substances from the blood to create urine. The urine then travels from the kidneys to the bladder through the ureters before being excreted from the body through the urethra.
Blood is not "converted" into urine. Urine is EXTRACTED from the blood by the two organs called the "kidneys".

primary symptom is inability to urinate completely.urge to urinate completely.this condition is averted more during nights ,called nocturia.this occurs bec due to hormone imbalance prostate enlarges greatly thus narrowing the urethral tube.so backing up of urine occurs in kidneys ,kidneys stores urine for time to time it causes infection.as a result kidneys do not filterate.
That pair of organs is called as kidneys. They are placed besides your vertebral column in the abdomen. Kidneys filter about 180 liters of fluid per day. About 177 to 178 liters of the fluid is absorbed back. Rest is excreted as urine.
