PURPOSE:To present our experience with robot-assisted simple prostatectomy in patients with large gland adenoma (>100 g) that would not be amenable to transurethral treatments.
PATIENTS AND METHODS:From August 2009 to May 2011, 13 robot-assisted simple suprapubic prostatectomies were performed in patients with symptomatic large gland (>100 g) prostatomegaly on transrectal ultrasonography (mean 163 cc). Essential aspects of our technique include a transverse cystotomy just proximal to the prostatovesical junction and use of a robotic tenotomy grasper to aid in adenoma dissection.
RESULTS:Mean operative time was 179 minutes (range 90-270 min), and mean estimated blood loss was 219 mL (range 50-500 mL). Mean hospital stay was 2.7 days (range 1-8 d), and the mean urethral catheterization time was 8.8 days (range 5-14 d). None of the patients needed blood transfusion. One patient had an intraoperative urinary leak after bladder closure that was managed with prolonged urethral catheterization (14 d). Histopathologic analysis confirmed benign prostatic hyperplasia (BPH) in all patients, and mean specimen weight on pathologic examination was 127 g (range 100-165 g). Mean follow-up duration was 7.2 months with all patients having a minimum of a 4-month follow-up. Significant improvements were noted in the International Prostate Symptom Score (preoperative vs postoperative 18.1 vs 5.3, p< 0.001) and the maximum urine flow rate (preoperative vs postoperative 4.3 vs 19.1 mL/min, P< 0.001).
CONCLUSIONS: Minimally invasive robot-assisted simple prostatectomy is technically feasible in patients with large volume (>100 g) BPH and is associated with significant improvements in obstructive urinary symptoms. Surgeons with robotic expertise may consider using this approach for treatment of their patients with large volume BPH.
