Robotic assisted laparoscopic simple suprapubic prostatectomy – The Smith Institute for Urology experience with an evolving technique

ObjectiveDespite a multitude of minimally invasive surgical options available for benign prostatic enlargement, open simple prostatectomy (OSP) remains the standard for large prostates (typically greater than 100 g). OSP, however, is associated with significant morbidity. Recently, a few reports touting robotic application to simple prostatectomy have been published. Herein, we reviewed our series of robotic assisted laparoscopic simple suprapubic prostatectomy (RALSSP) and detailed modifications in our technique as our experience increased.MethodsAll RALSSP cases performed between January 2013 and January 2014 were reviewed for demographics, pre-operative features, and perioperative outcomes. All parameters were tabulated and mean values were calculated. Student's t-test was utilized with p < 0.05 deemed significant. Details regarding surgical technique were reviewed and highlighted.ResultsFifteen patients underwent RALSSP during this period. Mean age of these men was 68.7 years. Mean body mass index (BMI) was 28.5 kg/m2. American Society of Anesthesiologists (ASA) score was on average 2.6. Average International Prostate Symptom Score (IPSS) was 16.2 with the majority of men experiencing some adverse clinical sequela of such benign prostatic hyperplasia (BPH). For those patients not in retention, preoperative post-void residual (PVR) was 428 mL. All patients underwent successful RALSSP without need for conversion or need for blood transfusion. Mean estimated blood loss (EBL) was 290 mL. Five patients underwent other concurrent procedures (e.g., cystolithotomy). Mean length of hospital stay (LOS) was 2.4 days and only five patients required continuous bladder irrigation (CBI) postoperatively. Postoperative PVR improved to a mean of 33 mL and IPSS improved to 4.5 (p < 0.001). No major complications were identified. Adaptation of low transverse cystotomy, utilization of a robotic tenaculum in the #3 arm with its control by a surgeon on a second console, and the utilization of mucosal advancement have all subjectively aided in performance of RALSSP and perioperative outcomes.ConclusionRALSSP allows for feasible performance of prostate adenoma enucleation with low risk of blood transfusion, short LOS, and significant improvement in IPSS and PVR; all while maintaining a minimally invasive approach. The use of a robotic tenaculum controlled by the secondary console and the mucosal advancement facilitate excellent outcomes and may play a role in minimizing hematuria and need for CBI.
