Impact of previous transurethral prostate surgery on health-related quality of life after radical prostatectomy: Does the interval between surgeries matter?

PURPOSE: To assess the impact of previous transurethral surgery for benign prostate enlargement (BPE) and time interval between procedures on functional outcomes and health-related quality of life (HRQOL) after radical prostatectomy (RP). METHODS: A propensity score-matched patient cohort [n = 685, (513 without previous BPE surgery, 172 with BPE surgery)] was created and HRQOL was pre- and postoperatively assessed using validated questionnaires (EORTC QLQ-C30). Urinary continence was measured via ICIQ-SF questionnaire and pad usage. Multivariable analysis included binary logistic and Cox regression models (p < 0.05). RESULTS: Median follow-up was 18 months. There was no significant difference in recurrence-free survival in multivariate analysis (HR 0.66, 95%CI 0.40-1.07, p = 0.093). We observe higher mean ICIQ-SF scores (5.7 vs. 8.2, p < 0.001) and daily pad usage (1.3 vs. 2.5, p < 0.001), and decreased continence recovery (OR 0.46, 95%CI 0.30-0.71, p < 0.001) for patients with BPE surgery. Postoperative general HRQOL scores were significantly lower for patients with previous BPE surgery (70.6 vs. 63.4, p = 0.003). In multivariate analysis, continence recovery (OR 5.19, 95%CI 3.10-8.68, p < 0.001) but not previous BPE surgery (0.94, 0.57-1.54, p = 0.806) could be identified as independent predictors of good general HRQOL. There was no significant correlation between time interval between both surgeries and continence (p = 0.408), and HRQOL (p = 0.386) outcomes. CONCLUSIONS: We observe favourable continence outcomes for patients without previous BPE surgery. Our results indicate that RP can be safely performed after transurethral BPE surgery, regardless of the time interval between both interventions.

Benefits and Limitations of Transurethral Resection of the Prostate Training With a Novel Virtual Reality Simulator.

PURPOSE: Profound endourological skills are required for optimal postoperative outcome parameters after transurethral resection of the prostate (TURP). We investigated the Karl Storz (Tuttlingen, Germany) UroTrainer for virtual simulation training of the TURP. MATERIALS AND METHODS: Twenty urologists underwent a virtual reality (VR) TURP training. After a needs analysis, performance scores and self-rated surgical skills were compared before and after the curriculum, the realism of the simulator was assessed, and the optimal level of experience for VR training was evaluated. Statistical testing was done with SPSS 25. RESULTS: Forty percent of participants indicated frequent intraoperative overload during real-life TURP and 80% indicated that VR training might be beneficial for endourological skills development, underlining the need to advance classical endourological training. For the complete cohort, overall VR performance scores (P = 0.022) and completeness of resection (P < 0.001) significantly improved. Self-rated parameters including identification of anatomical structures (P = 0.046), sparing the sphincter (P = 0.002), and handling of the resectoscope (P = 0.033) became significantly better during the VR curriculum. Participants indicated progress regarding handling of the resectoscope (70%), bleeding control (55%), and finding the correct resection depth (50%). Although overall realism and handling of the resectoscope was good, virtual bleeding control and correct tissue feedback should be improved in future VR simulators. Seventy percent of participants indicated 10 to 50 virtual TURP cases to be optimal and 80% junior residents to be the key target group for VR TURP training. CONCLUSIONS: There is a need to improve training the TURP and VR simulators might be a valuable supplement, especially for urologists beginning with the endourological desobstruction of the prostate.
