Abstract
Introduction: Laparoendoscopic single-site surgery (LESS), robot-assisted (RA), and retroperitoneoscopic (R) surgery expand the armamentarium of minimally invasive surgery (MIS). As information on the use of these surgical approaches in daily routine is limited, we conducted a survey among German urologists. Materials and Methods: In 2017, all urology departments in Germany received a questionnaire evaluating practice patterns of MIS in the retroperitoneum. Chi-Square test was performed for statistical analyses. The response rate was 51.1% (162/311) including 23 universities. Results: R adrenalectomy and (partial) nephrectomy are performed by 32.7–40.1% of all departments. Transperitoneal LESS adrenalectomy and nephrectomy are performed by 8.6–11.7%. Retroperitoneal RA adrenalectomy and (partial) nephrectomy are performed by 6.2–13.0%. There was no difference in the R and LESS approach between (non)-university departments. Retroperitoneal RA access is more frequently used in university hospitals (all p < 0.01). If performed, mean counts within the last 12 months were < 5 for R, LESS, and RA adrenalectomy; and < 20 for R, LESS, and RA (partial) nephrectomy. Conclusion: Our survey provides a detailed insight into MIS in the retroperitoneum in German urology departments. Numbers of adrenalectomies as well as R, transperitoneal LESS and retroperitoneal RA procedures are low. Retroperitoneal RA surgery is more common in universities. Comprehensively, our survey proves that these approaches are not standard approaches yet.
