• INTRODUCTION:

  Urologic malignancies are often diagnosed at an older age, and are increasingly managed utilizing robotic-assisted surgical techniques. As such, we assessed and compared peri-postoperative complication rates following robotic urologic surgery in elderly and younger patients.

  MATERIALS AND METHODS:

  A retrospective analysis of IRB-approved databases and electronic medical records identified patients who underwent robotic-assisted urologic surgery between December 2003-September 2013. Patients were grouped according to surgical procedure (partial nephrectomy, radical cystectomy, radical prostatectomy) and age at surgery (<= 74 or >= 75 years old). Associations between age, comorbidities, Charlson comorbidity index (CCI), and patient outcomes were evaluated within each surgery type.

  RESULTS:

  97.5% and 2.5% of patients were <=74 or >= 75 years old, respectively. Cystectomies, partial nephrectomies and prostatectomies accounted for 3.5%, 9.5% and 87.1% of surgeries, respectively. Within cystectomy, nephrectomy and prostatectomy groups, 24.4%, 12.5% and 0.6% patients were >= 75 years old. Within each surgical type, elderly patients had significantly elevated CCI scores. Length of stay was significantly prolonged in elderly patients undergoing partial nephrectomy or prostatectomy. In elderly cystectomy, partial nephrectomy and prostatectomy patients, 36.7%, 14.3% and 5.9% suffered >= 1 Clavien grade 3-5 complication, respectively. Major complications were not significantly different between age groups. A qualitatively similar pattern was observed regarding Clavien grade 1-2 complications.

  CONCLUSIONS:

  The risks of robotic-assisted urologic surgery in elderly patients are not significantly elevated compared to younger patients.
