[Spontaneous subcapsular hematoma of the kidney due to renal colic: a case report and analysis of causes].

Renal colic is characterized by acute pain in the lower back. The most common cause of this condition is a stone blocking the outflow of urine from the kidney. Long-term obstruction leads to hypertension of the renal pelvis, which leads to the development of urinoma, is the cause of rupture of the renal pelvis, and in rarer cases to bleeding with stages of subcapsular hematoma. The article presents a case of a 51-year-old patient who was admitted with complaints of intense pain in the lumbar region on the left. The anamnesis included repeated attacks of renal colic, acquired independently. Computed tomography revealed a subcapsular fluid accumulation measuring 5080 mm, probably hematoma. Ultrasound examination confirmed the presence of a subcapsular hematoma. The patient underwent drainage of the upper urinary tract with a ureteral stent. The postoperative period was without surgery. Currently, regression of the subcapsular hematoma is observed.
