When kidney calculi is in the renal pelvis, he will be discharged from the kidney through the ureter, bladder and urethra. Stones are easily located at the end of ureter and urethral orifice, which are relatively small and easy to block. Therefore, drug treatment of kidney calculi should also consider whether stones will be blocked, so as not to block stones and cause hydronephrosis, which is even more troublesome.
Extended data:
The symptoms of kidney calculi depend on the size, shape, location, infection, obstruction and other complications of stones. Kidney calculi's patients are mostly asymptomatic unless kidney calculi falls from the kidney to the ureter, causing urinary tract obstruction in the ureter. Common symptoms include low back pain and abdominal cramps, nausea, vomiting, irritability, bloating and hematuria. If combined with urinary tract infection, chills and fever may also occur. Acute renal colic often makes patients feel unbearable pain.
