[Use of surgical biopsy of the kidney in the differential diagnosis of various forms of arterial hypertension]. / Primenenie operatsionnoi biopsii pochki v differentsial'noi diagnostike razlichnykh form arterial'noi gipertonii.

To make a more precise diagnosis, kidney biopsy was performed in 17 patients with a severe course of blood hypertension due to a mild urinary syndrome. Taking into account the high risk of hemorrhagic complications in such patients, an operational biopsy was performed (in 13 patients in a open way and in 4 patients in a semiopen one). As a result of the histologic investigation of kidney bioptates, the diagnosis was changed in more than half patients. In the postoperative period, almost all the patients had microhematuria, 1 subject having massive bleeding into the retroperitoneal cavity that required nephrectomy. In 3 subjects the postoperative period was complicated by wound suppuration.
