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.</p> <p>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 50×80 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.</p></abstract><trans-abstract xml:lang="ru"><p>Почечная колика характеризуется острой болью в пояснице вследствие нарушения оттока мочи из почки. Наиболее частой причиной данного состояния является камень, блокирующий отток мочи из почки. Длительно существующая обструкция приводит к гипертензии в чашечно-лоханочной системе, которая чревата развитием уриномы, а в более редких случаях – кровотеченем с формированием подкапсульной гематомы.</p> <p>В статье представлено редкое клиническое наблюдение – спонтанная подкапсульная гематома почки вследствие почечной колики. Данное осложнение потенциально представляет угрозу жизни пациента. Только своевременные диагностика и лечение данного состояния позволят избежать грозных осложнений. В статье также анализируются причины, приводящие к данному состоянию.</p></trans-abstract><kwd-group xml:lang="en"><kwd>renal colic</kwd><kwd>subcapsular hematoma</kwd><kwd>ureteral stenting</kwd><kwd>urolithiasis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>почечная колика</kwd><kwd>подкапсулярная гематома почки</kwd><kwd>стентирование мочеточника</kwd><kwd>мочекаменная болезнь</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Hyams ES, Korley FK, Pham JC, Matlaga BR.
