PURPOSE: Pudendal nerve injection is used as a diagnostic procedure in the vulvar region and for therapeutic purposes, such as in @entity2411 . Here, we provide a new, easy-to-perform perineal injection technique. @entity1 AND METHODS: We analyzed 105 perineal injections into the pudendal nerve with a local anesthetic (LA), @entity8162 in 20 @entity1 . A 0.4  *  40  mm needle was handled using a stop-and-go technique while monitoring the @entity1 's discomfort. The needle was placed 1-2  cm laterally to the dorsal introitus. After aspiration, a small amount of LA was applied. After subcutaneous anesthesia, the needle was further advanced step-by-step. Thus, 5  ml could be applied with little discomfort to the @entity1 . Anesthesia in the pudendal target region was the primary endpoint of our analysis. RESULTS: In 93 of 105 injections (88.6  %), complete perineal anesthesia was achieved with a single injection. 12 injections were repeated. These injections were excluded from the analysis. Severity of injection @entity158 , on visual analog scale (VAS) from 0 to 100, was 26.8 (95  % CI 7.2-46.4). Age (b  =  0.33, p  <  0.01) and the number of previous injections (b  =  0.35, p  <  0.01) inversely correlated with injection @entity158 . Injection @entity158 and anesthesia were not affected by BMI, the number and the side of previous injections, or order of injection. A reversible @entity907 was common, but no serious adverse effects occurred. CONCLUSION: Perineal pudendal injection is an effective and safe technique for anesthesia in diagnostic (vulva biopsy) and therapeutic indications ( @entity3815 ), and regional anesthesia in perinatal settings.
