A painful blockage of the ureter, causing back pressure on the kidney which fills with urine and swells [After Joseph Diet! (1804-78), Polish physician].
Acute obstruction of a kidney causing severe pain in the loins. The obstruction usually occurs at the junction of the renal pelvis and the ureter, causing the kidney to become distended with accumulated urine. Sometimes the pelvis drains spontaneously, with relief of pain, but acute decompression of the kidney may be required with surgical relief of the obstruction (pyeloplasty).
A sudden, severe attack of gastric pain, chills, fever, nausea, and collapse. In cases of floating kidney, the ureter becomes kinked and urine is obstructed, producing symptoms of renal colic.
An event that happens when a kidney shifts out of its usual position, causing a kink in the ureter—the tube that transports urine from the kidney to the bladder. This leads to a sudden onset of intense pain in the lower back area. However, when the patient lies down, the kidney repositions itself, the ureter unkinks, the pain subsides, and urine flows freely again.
