[Critical haematuria after prostate biopsies with RIVAROXABAN. Case report].

Managing patients with new oral anticoagulants in perioperative period is not yet well protocolized. We report a clinical case of a critical haematuria after prostate biopsies to a patient treated with RIVAROXABAN. Monitoring and treatment of the haematuria have been difficult due to the lack of biological control and antidote for this treatment.

[Severe late rectal bleeding after biopsy of prostate: a case report].

The biopsy of the prostate is a common medical act, which is little invasive and can easily be practiced in external care. Some cases of early rectal or urinary bleedings, which mainly stopped spontaneously, have been described in the literature. The case reported here is that of a patient whose hemorrhagic syndrome arose more than two weeks after the biopsy and required an endoscopic haemostatic treatment.

The coexistence of several tumours in the same patient is a rare phenomenon and corresponds to the multiple primary tumour (MPT) syndrome. The most frequently diagnosed MPT include gastrointestinal tumours associated with urological tumours. Overexpression of the STAG1 gene could explain the development of several solid tumours and could be the origin of the multiple primary tumour syndrome.
