腎摘除術を要した重症腎感染症の後方視的検討

概要

Patients who contract severe renal infections often suffer from urosepsis. Therefore, early diagnosis and treatment are required. Sometimes, the treatment with antibiotics is not enough for control of the infections. Most of the patients also require surgical interventions including transurethral drainage and nephrectomy. Twenty-two patients with severe renal infections treated between April 2010 and October 2019 at our institute were evaluated retrospectively. Eleven patients had undergone nephrectomy. Open nephrectomy was performed on 10 patients. Laparoscopic nephrectomy was attempted in the other patient but was converted to open nephrectomy because severe adhesion was found around the tissues. Nephrectomy was performed by the retroperitoneal approach on 9 patients and by the transperitoneal approach on 2 patients. The reteroperitoneal approach was used on two patients who suffered postoperative colon perforation. Inflammatory involvement of renal pelvis, hilum and adjacent structures leads to dense fibrotic reaction and obliteration of tissue planes, which makes the nephrectomy procedure challenging. Therefore, it is important to choose the most appropriate nephrectomy procedure for each patient when they have contracted severe renal infections.
