Robot-assisted vs ultrasonography-guided transversus abdominis plane (TAP) block vs local anaesthesia in urology: results of the UROTAP randomized trial.

OBJECTIVES: To prospectively analyse robotically administered transperitoneal transversus abdominis plane (robot-assisted transversus abdominis plane [RTAP]) compared with both ultrasonography-guided transversus abdominis plane (UTAP) and local anaesthesia (LA) with regard to pain control and narcotic use in patients undergoing robot-assisted prostatectomy (RARP) or robot-assisted partial nephrectomy (RAPN). SUBJECTS/PATIENTS AND METHODS: Patients undergoing RARP or RAPN were randomized in a single-blind 2:2:1 fashion to RTAP:UTAP:LA, with the study powered to evaluate superiority of UTAP to LA and non-inferiority of RTAP to UTAP. We compared time to deliver the block, operating room time, postoperative pain scores using the visual analogue scale, and intra-operative and postoperative analgesia consumption. RESULTS: A total of 143 patients were randomized and received treatment. There was no significant difference in patient baseline characteristics. UTAP did not demonstrate superiority to LA in terms of pain control. RTAP and LA were faster to administer than UTAP (time to perform block 2.5 vs 2.5 vs 6.25 min; P < 0.001). There was no difference in postoperative narcotic, acetaminophen, ketorolac or ondansetron requirements among the three groups (P > 0.05). The study was terminated early due to the unexpected efficacy of LA. CONCLUSION: This study showed that UTAP and RTAP do not provide superior pain control to LA. The efficiency, effectiveness, and ease of administration of LA make it an excellent option for first-line therapy for postoperative analgesia.

Long-term oncological and functional outcomes support use of low-dose-rate brachytherapy with or without external beam radiation in young men (≤60 years) with localized prostate cancer.

PURPOSE: To evaluate the oncological and functional outcomes of young men treated with low-dose-rate brachytherapy (BT) for prostate cancer (PCa). MATERIALS AND METHODS: 423 men aged ≤60 years with clinically localized PCa were treated with BT ± external beam radiation. Biochemical failure was defined by Phoenix criteria. Freedom from biochemical failure (FFbF) and cancer-specific survival (CSS) at 10 and 15 years were estimated by the Kaplan-Meier method with the log-rank test to compare outcomes between National Comprehensive Cancer Network risk groups. The Cox proportional hazards model was used to determine significant predictors for FFbF and CSS. RESULTS: Median followup was 9.9 years (range, 5.1-21.7). Median age was 57 years (range, 39-60), and median prostate-specific antigen was 6.1 ng/mL (range, 0.8-71). Overall, 10- and 15-year FFbF rates were 89% and 88%; 10- and 15-year CSS rates were 99% and 98%. Increasing disease risk was associated with lower FFbF and CSS (p < 0.0001). Biologically effective dose (p < 0.0001) and use of external beam radiation (p = 0.005) were significantly associated with higher FFbF. In men potent before BT, 64% (151/237) had preserved erectile function at a median 10.2 years. There was no significant difference between treatment groups with respect to long-term urinary function (p = 0.56). CONCLUSIONS: Younger men treated with BT experience excellent long-term PCa control with low rates of treatment-related toxicity.
