To compare the reduction of the bedrest time of the patient after percutaneous renal biopsy from 24 hours to 8 hours in relation to the occurrence of complications evaluated by the Nursing Outcome Classification (NOC) indicators.

Percutaneous renal biopsy (BRP) is an important procedure for the diagnosis, prognostic evaluation and therapeutic orientation of several kidney diseases. Although it is considered a safe procedure, BRP complications can occur and, most of the time, are related to the risk of bleeding and the main consequence of BRP. Complications include macroscopic hematuria and hematoma requiring blood transfusion, surgical intervention, or invasive procedure. Since hemorrhagic complications continue to be the highest risk after BRP due to severity and potential life-threatening risk, there is an effort to minimize the risk of bleeding by checking blood clotting markers prior to the procedure, uncontrolled hypertension and the use of antiplatelet drugs and anticoagulants. The relevance of this study is to seek better evidence for clinical practice, considering the lack of Brazilian studies on the subject and the positive impact on patient comfort, besides the reduction of costs for the institution and overload in the work of the multidisciplinary team. In addition, it will contribute to the strengthening of the use of NOC in clinical practice and to the improvement of nursing knowledge.
