Patient's question:
Main symptoms: Onset time of kidney stones: 2 months Test results: Ultrasound shows kidney stonesDoctor's answer:
Multiple kidney stones, defined as two or more stones within the kidneys, are referred to as multiple kidney stones. The number, size, shape, location, and presence of complications such as infection of multiple kidney stones can affect the symptoms during a kidney stone episode. The symptoms of multiple kidney stones primarily include renal colic, hematuria, pyuria, acute obstructive oliguria, anuria, and chronic renal failure. Compared to kidney stone conditions with only one stone, the symptoms of multiple kidney stones are more pronounced.Symptoms of multiple kidney stones:
⑴ Chronic renal failure:
⑵ Acute obstructive oliguria or anuria: Acute renal colic is often accompanied by obvious gross or microscopic hematuria. In rare cases, complete obstruction caused by stones may result in no hematuria. If stones are complicated by infection, both hematuria and pyuria may occur. In some cases, long-term stimulation by kidney stones can lead to metaplasia of renal epithelial cells, ultimately resulting in squamous cell carcinoma, presenting as persistent severe hematuria. Hematuria typically disappears a few days after the stone stops moving.
⑶ Patients with a solitary kidney (contralateral kidney absence or non-function) or bilateral ureteral stones may cause acute obstructive oliguria or anuria. Hyperkalemia and severe acidosis. Clinical manifestations generally include pain in the affected renal region, oliguria or anuria, uremia, heart failure, and hypertension.
⑷ Renal colic: In patients with a solitary kidney or bilateral kidney stones, long-term obstruction or infection of stones can lead to chronic renal failure.
