Utilizing Local Anesthesia Only for Penile and Scrotal Urologic Surgery: A Prospective Study on Patient Tolerability and Surgical Outcomes for a Sedation-free Option

Abstract

ObjectiveTo prospectively assess surgical outcomes, complications, and patient-reported tolerability of invasive scrotal surgeries under local anesthesia (LA) alone, without sedation, compared to tolerability of penile procedures commonly performed in this manner. MethodsAdult patients undergoing penile and scrotal surgeries under LA only were enrolled from August 2022 to June 2023 (NCT05617261). Demographics, surgeon-perceived and patient-reported pain, and surgical variables were collected. Tolerability to the procedures and future anesthetic choice for a repeat procedure was assessed on follow-up. Complication data was collected, including recurrence, infection, excessive pain, and emergency room and family physician visits. Results107 patients were enrolled with a mean age ± SD of 42.2 ± 16.4 years. There was a 100% procedural success rate and no cases of perioperative complications or escalation of anesthetic. 92.4% (n=97) of patients indicated they would opt for LA only for a hypothetical repeat procedure. Of the minority opting for general anesthetic, most indicated discomfort or preferring an element of amnesia. No differences between intraoperative pain or tolerability scores of invasive scrotal procedures compared to penile procedures were observed. On univariate analysis, longer procedure duration (p=0.003), cannabis use (p=0.01), and higher intra-operative pain (p=0.005) was associated with lower tolerability. ConclusionLA alone in an office-based setting is promising for scrotal surgeries. It offers similarly high patient tolerability compared to procedures that are routinely performed under LA, with the preservation of outcomes. Adopting this method has the potential for substantial cost savings, reduced wait times, enhanced accessibility, and improved surgical efficiency.
