Association of surgeon and hospital volume with short-term outcomes after robot-assisted radical prostatectomy: Nationwide, population-based study.

ABSTRACT:

Background and objective

Few studies have investigated the association between surgical volume and outcome of robot-assisted radical prostatectomy (RARP) in an unselected cohort. We sought to investigate the association between surgical volume with peri-operative and short-term outcomes in a nation-wide, population-based study group.

Methods

9,810 RARP's registered in the National Prostate Cancer Register of Sweden (2015-2018) were included. Associations between outcome and volume were analyzed with multivariable logistic regression including age, PSA-density, number of positive biopsy cores, cT stage, Gleason score, and extent of lymph node dissection.

Results

Surgeons and hospitals in the highest volume group compared to lowest group had shorter operative time; surgeon (OR 9.20, 95% CI 7.11-11.91), hospital (OR 2.16, 95% CI 1.53-3.06), less blood loss; surgeon (OR 2.58. 95% CI 2.07-3.21) hospital (no difference), more often nerve sparing intention; surgeon (OR 2.89, 95% CI 2.34-3.57), hospital (OR 2.02, 95% CI 1.66-2.44), negative margins; surgeon (OR 1.90, 95% CI 1.54-2.35), hospital (OR 1.28, 95% CI 1.07-1.53). There was wide range in outcome between hospitals and surgeons with similar volume that remained after adjustment.

Conclusions

High surgeon and hospital volume were associated with better outcomes. The range in outcome was wide in all volume groups, which indicates that factors besides volume are of importance. Registration of surgical performance is essential for quality control and improvement.

Project description:ObjectivesTo describe in detail the techniques for transvesical robot-assisted radical prostatectomy (RARP) using the da Vinci Si/Xi system (Intuitive Surgical, Sunnyvale, CA, USA) and to evaluate functional and oncological outcomes in 35 patients with prostate cancer.Patients and methodsThirty-five patients with localized prostate cancer were enrolled for transvesical RARP. The patients' preoperative data (mean ± sd age 63.4 ± 8.1 years, body mass index 28.6 ± 5.3 kg/m2 , total prostate-specific antigen 10.8 ± 4.9 ng/mL and prostate volume 30.6 ± 14.4 mL, and median [interquartile range {IQR}] biopsy Gleason score 6 [6-7], and International Index of Erectile Function [IIEF]-5 score 18 [16-20]) were collected. Preoperative assessment revealed 28 cases of cT2a and seven cases of cT2b disease. All patients were continent preoperatively (defined as no pad required or one dry pad per day as a precaution). Surgical results and peri-operative complications were assessed. All patients were followed up for at least 12 months postoperatively.ResultsThe mean operating time was 150 ± 35 min. Estimated blood loss was 100 ± 45 mL. Urinary infection was noted in one patient and managed with levofloxacin. Another patient complained of nocturia on postoperative day 14, which was relieved with solifenacin succinate. Urethral catheters were removed on postoperative day 7. Thirty-two patients achieved immediate urinary continence, with three patients returning to full continence on postoperative day 14. Postoperative pathology confirmed 24 pT2a cases, nine pT2b cases and two pT2c cases (median [IQR] Gleason score 6 [6-7]). Positive surgical margins were found in four patients (11.4%). No urethral stricture or urinary leakage was noted on urethrocystography taken 3 months after surgery. Urodynamic studies were performed preoperatively and 6 months after surgery: median (IQR) maximum urinary flow 12.2 (10.2-14.9) vs 13.7 (10.1-15.0) mL/s; bladder capacity 385.3 (351.3-410.2) vs 370.2 (330.1-395.4) mL; and voiding phase detrusor contractility 38.5 (27.8-42.3) vs 35.6 (28.3-41.3) mmH2 O, respectively. During a minimum of 12 months of follow-up, no biochemical recurrence was noted in any patient. The median (IQR) IIEF-5 score was 17 (16-19).ConclusionsThe transvesical approach is a valid alternative to RARP in selected patients, providing promising postoperative urinary continence. Long-term functional and oncological results require further investigation.
