Robot-Assisted Radical Prostatectomy After Prior Transurethral Resection of Prostate: An Analysis of Perioperative,...

We performed a retrospective comparison of surgical, oncologic, and functional outcomes after robot-assisted radical prostatectomy between patients who have undergone prior transurethral resection of prostate (TURP) to TURP-naive patients. Past robotic prostatectomy hospital data were scrutinized to form two matched groups of patients: those who have undergone prior TURP and TURP-naive patients. The perioperative and pathologic data along with functional and oncologic outcomes for a period of 3 years were compared between groups. Compared with TURP-naive patients, prior TURP patients experienced longer robot-assisted laparoscopic prostatectomy times (p < 0.001), increased incidence of bladder neck reconstruction (p = 0.03), greater blood loss (p = 0.0001), and lesser nerve sparing (p < 0.01). Complication rates (p = 0.3), positive surgical margin (p = 0.4), extracapsular disease (p = 0.3), or seminal vesicle invasion (p = 0.1) were comparable between groups. Continence (p = 0.5) and potency (p = 0.1) at 1 year were not different between groups. Biochemical recurrence rates were not different at 3 years (p = 0.9). Diabetes slowed recovery of continence in patients with prior TURP compared with TURP-naive patients until 6 months after surgery. Although prior TURP makes subsequent robotic prostatectomy more technically demanding, it can be safely performed by experienced surgeons without compromising long-term functional or oncologic outcomes.
