It is common to experience a moderate amount of back, flank or side discomfort after lithotripsy or ureteroscopy. Your urologist will usually give you a prescription for pain medication. You may also experience some pain when passing stone fragments. You may apply ice packs every two hours while awake for the first 24 hours on the treatment side if you need additional pain relief. If ice packs do not help, try soaking in warm water.
It is normal to see some bruising of the skin in the kidney area on the back after ESWL. Bruising on the front side may occur in patients who are very thin. The bruising will resolve and requires no treatment.
Blood in the urine:
Most patients see blood in their urine after ESWL or ureteroscopy. This should resolve with time and drinking lots of water. The urine can look red even when there is only a very small amount of blood in it. If you have a ureteral stent in place, you can expect to have blood in the urine intermittently until the stent is removed. Your urologist will explain the process and what to expect. Increased physical activity may increase the amount of blood in the urine.
If you have a stent you will likely have the urge to urinate frequently and in small amounts. This is because the stent can irritate the inside of the bladder and make you feel as if you need to urinate.
Some patients, particularly men with enlarged prostates, may have some difficulty urinating after anesthesia. Walking, relaxing, or taking a warm shower may help you urinate and make you more comfortable. If however you cannot urinate and you feel distended, contact your urologist or go to an emergency room and ask that they call your urologist.
Nausea and Vomiting:
It is common to have some nausea and occasionally vomiting for the first 12 to 24 hours after the procedure and the anesthetic. If you cannot keep fluids down and continue to vomit the day after the procedure you should contact your urologist.
What to Eat and Drink:
It is very important to drink plenty of fluids after the procedure (at least 6- to 8-oz glasses). Clear liquids such as water, ginger ale, gatorade, and chicken broth are best if you are nauseated. If you are not nauseated, you may resume your regular diet. Your urologist may suggest diets to help prevent kidney stones in the future.
You will be given a urine strainer and container to collect stone fragments when you leave the hospital. Do your best to collect stones from your urine so that you may bring them to your urologist office for analysis. You can urinate into the container and then pour the urine through the strainer. Identifying the chemical composition of the stone from its fragments may help your urologist prevent further stones from forming. Strain your urine for seven to 10 days after your procedure.
