i need to know whether you mean blocked urethra (the tube that carries urine from the bladder to the outside of the body) or blocked ureter (one of the two tubes that lead each from one of the kidneys to the urinary bladder). my late father once had a kidney stone that blocked one of his ureters causing hydronephrosis - his urine was backing up into the kidney. it was very dangerous and his urologist had to install a stent to keep the ureter open wider until he passed the kidney stone. during the time he had the stent he became temporarily incontinent and had to wear men's depends but after it was resolved that problem went away. [years later however both his kidneys failed completely. since he was dying of cancer at the time no one ever figured out why. ] if you have a blocked ureter the kidney to which it belongs will develop hydronephrosis unless it is treated; a urologist would need to tend to that and quickly. if on the other hand what is blocked is not one of the ureters but your urethra that would also be an emergency possibly a much more immediately urgent one. if the urethra is totally blocked the bladder cannot empty at all and will eventually burst upward through the dome. depending upon why the urethra is blocked treatment may involve passing a catheter into the bladder or even emergency surgery to remove the obstruction. if the urethra is partially blocked only a small amount of urine may emerge the bladder will become overdistended and a uti will be highly likely to develop; plus the condition will be extremely painful. in that case it becomes necessary to have a catheter passed into the bladder to empty it and then the condition that caused the blocked urethra treated. in men this is most likely to be caused by a swollen prostate gland. in women injury to the urethra and certain types of vaginal swelling are most likely though many other conditions are possible. in either case - whether it's your urethra or one of your ureters that is blocked - it needs medical attention. the sooner the better. as for the skin rash a doctor would have to look at that to see if it's connected but i do know that in actual kidney failure small crystals of uric acid or urea salts actually emerge through the pores of the skin but by the time this happens the person is near death and is not likely to be using a computer. the rash could still be connected in some way to the underlying condition though because it is true that either a blocked ureter or a blocked urethra result in toxins not being properly eliminated by the body. the most important thing is to get medical treatment for the blockage and then tend to the rest. good luck.
can a blocked utera cause backup in the kidney of toxins and create skin rash and bumps
