We aimed to compare outcomes of TURBT using spinal anaesthesia (SA) alone versus SA+ONB in terms of rates of obturator reflex, bladder perforation, incomplete tumour resection, tumour recurrence and local anaesthetic toxicity. METHODS: We conducted a comprehensive search of electronic databases (MEDLINE, PUBMED, EMBASE, CINAHL, CENTRAL, SCOPUS, Google Scholar and Web of Science), identifying studies comparing the outcomes of TURBT using spinal anaesthesia versus spinal with an obturator nerve block. The Cochrane risk-of-bias tool for RCTs and the Newcastle-Ottawa scale for observational studies were used to assess the included studies. Random effects modelling was used to calculate pooled outcome data. RESULTS: Searches of electronic databases resulted in 107 articles, from which four randomised control trials (RCTs) and three cohort studies met the eligibility criteria, enrolling a total of 448 patients. The use of spinal anaesthesia with an obturator nerve block was associated with a significantly reduced risk of obturator reflex (p <0.00001), bladder perforation (p=0.02), incomplete resection (p <0.0001) and 12-month tumour recurrence (p=0.005). Obturator nerve block was not associated with an increased risk of local anaesthetic toxicity (0/159). CONCLUSIONS: Our meta-analysis suggests that TURBT employing spinal anaesthesia with an obturator nerve block is superior to the use of spinal anaesthesia alone. During the COVID-19 pandemic, where avoidance of aerosol-generating procedures (AGPs) such as a general anaesthesia is paramount, the use of an obturator nerve block with spinal anaesthesia is essential for the safety of both patients and staff without compromising care. Further high-quality RCTs with adequate sample sizes are required to compare the different techniques of obturator nerve block as well as comparing this method to general anaesthesia with complete neuromuscular blockade.
