Consensus statements on the management of metastatic renal cell carcinoma from the Hong Kong Urological Association and the Hong Kong Society of Uro-Oncology 2019.

Background: To establish a set of consensus statements for the management of metastatic renal cell carcinoma, a total of 12 urologists and clinical oncologists from two professional associations in Hong Kong formed an expert consensus panel.

Methods: Through a series of meetings and using the modified Delphi method, the panelists presented recent evidence, discussed clinical experiences, and drafted consensus statements on several areas of focus regarding the management of metastatic renal cell carcinoma. Each statement was eventually voted upon by every panelist based on the practicability of recommendation.

Current evidence for robotic surgery in radical cystectomy.

Robotic-assisted radical cystectomy (RARC) has been gaining momentum as an alternative to its conventional open radical cystectomy (ORC) for the management of invasive bladder cancer. Although RARC, in general, demonstrated less blood loss and shorter hospital stay than ORC, whether there is any significant difference in the overall complication rate still requires further investigation. Thus, both RARC and ORC share a similar oncology outcome, with comparable positive surgical margin rates, disease-free survival, and overall survival.

Surgical training for anatomical endoscopic enucleation of the prostate.

Anatomical endoscopic enucleation of the prostate has been proposed as a potentially superior benign prostatic hyperplasia surgery than conventional transurethral resection of prostate. However, the learning curve of the procedure is steep, hence limiting its generalisability worldwide. In order to overcome the learning curve, a proper surgical training is extremely important.
