Laparoscopic Nephrectomy for the Management of Xanthogranulomatous Pyelonephritis: Still a Challenging Procedure.
The aim of the study was to assess the feasibility of laparoscopic nephrectomy (LN) in the treatment of patients with xanthogranulomatous pyelonephritis (XGP). Retrospective review of medical records of 17 patients (mean age 60.0 ± 13.3 years) who underwent LN by a single surgeon from 2010 to 2018. Sociodemographic and clinical data including diagnosis, presenting clinical features, surgical management, and postoperative course were analyzed. LN was successfully performed in 15 (88.2%) patients. Two (12.5%) patients with disseminated disease were electively converted to open nephrectomy (ON) due to failure to progress. Two (11.8%) patients experienced intraoperative complications (grades 3b and 4b). Among patients in whom LN was successfully performed (n = 15), the mean operative time was 198.0 ± 107.1 min and was shorter when no intraoperative complications occurred (169.0 ± 48.1 min). Three (20%) of these patients required transfusions and nine (60.0%) required postoperative pelvic drainage (PD). Six (40%) patients experienced postoperative complications: one grade 1, four grade 2, and one grade 5. Mean hospital stay was 4.4 ± 4.3 days, and 3.4 ± 2.2 for those experiencing manageable or no complications. Among patients without postoperative complications (n = 6), mean hospital stay was shorter when no PD was placed (1.6 vs 2.6 days). LN is a feasible surgical option in patients with XGP although given the nature of XGP, it is associated with complications-nearly all manageable-which makes it a challenging surgical procedure. Advanced laparoscopic skills and experiences are needed. Dissemination of the disease is associated with the occurrence of more severe complications and conversion to ON. PD placement seems associated with shorter hospital stay.
