Ineffective Leoch 4 weeks before the second one, in which the haematoma occurred (4,000 impacts at intensity 4 and 1,000 at 5).
She had intense pain at the end of the surgery which required supplementary IV analgesia, although without haemodynamic alteration.
He was discharged after Leoch and was attended urgently 5 days later with poor general condition, asthenia, left lumbar pain and Hb of 8, and a haematoma was confirmed by ultrasound and CT scan. Creatinine elevation up to 1.8.

Ten days after the Leoch with Hb stabilised at 8 after administration of 3 red blood cell concentrates, and given the persistence of intense lumbar pain and fever (38-39º C), the haematoma was drained by lumbar incision, and the existence of a subcapsular haematoma, non-infected, without active bleeding, was confirmed. After 48 hours, renal function had normalised, fever had disappeared and only moderate pain typical of lumbotomies was reported. He was discharged 4 days after the operation. At 2 months renal ultrasound, IVUS and renal function were normal.
