Indications, feasibility and outcome of robotic retroperitoneal lymph node dissection for metastatic testicular germ cell tumours.

Sci Rep 2021 May 21;11(1):10700. Epub 2021 May 21.

Department of Urology and Paediatric Urology, Saarland University Medical Centre and Saarland University Faculty of Medicine, Homburg, Saar, Germany.

Data on robotic retroperitoneal lymph node dissection (R-RPLND) for metastatic testicular germ cell tumours (mTGCTs) are scarce and the use of R-RPLND itself is still under debate. The aim of our study was to evaluate the indications, feasibility and outcomes of R-RPLND, with special emphasis on differences between primary R-RPLND (pR-RPLND) and post-chemotherapeutic R-RPLND (pcR-RPLND) in mTGCTs. We retrospectively analysed the data of patients who underwent R-RPLND for mTGCT between November 2013 and September 2019 in two centres in Germany. Read More
