A TURP requires no external incision.
Inserted through the penis and the wire loop is guided by the surgeon so it can remove the obstructing tissue one piece at a time.The pieces of tissue are carried by fluid into the bladder and flushed out at the end of the procedure. TURP is generally done to relieve symptoms due to prostate enlargement, often due to BPH. BPH is a condition in which the prostate gland may become quite enlarged and cause problems with urination. Symptoms may include Problems with getting a urine stream started . Nocturia, urgency, dribbling. Monitor for hemorrhage for the first 24-48 hours.

If you are dehydrated they will produce less urine. If you drink a lot of fluid quickly, then more urine will be excreted –Thyroid sits on either side of trachea Isthmus connects two lobes Needs iodine to secrete t4 (thryoxine) and t3 (triiodonthronine) that increases metabolism Also secretes calcitonin that decreases excess calcium levels in the blood –HyperthyroidismToo much thyroid hormone SS: Increased appetite, yet loses weight.
