Objectives: To compare robotic-assisted laparoscopic prostatectomy with conventional retropubic radical prostatectomy in maintaining pre-surgery levels of urinary and sexual functioning and to evaluate the efficacy of nerve sparing in prostatectomies in protecting urinary functioning.
Material and methods: Patients (n = 385) receiving both surgical procedures were surveyed prior to surgery. Multiple measures, including the Expanded Prostate Cancer Index Composite, the Sexual Health Inventory for Men, and the International Prostate Symptom Score, assessed sexual and urinary function at an average of 12 months post-surgery.
Results: Across multiple measures, while controlling for pre-surgical sexual functioning, robotic-assisted surgery did not offer an advantage in maintaining sexual or urinary function an average of a year following the prostatectomy. Bilateral nerve sparing offered a strong and reliable advantage in the maintenance of sexual function, but not so regarding urinary function.
Conclusion: While robotic-assisted prostatectomies may offer a number of medical advantages over open procedures, we found no significant effect on important quality of life outcomes associated with the technique.
