Abstract Background To assess the prevalence of intraoperative penile erection in our endourology practice and the utility of intravenous ketamine in the management of the condition. Methods Of 402 endoscopic urological procedures performed in our clinic over a 4-year (2015–2019) period, a total of 9 cases with intraoperative penile erection impeding instrumentation during endourological surgery were included. Data on patient age, weight, height, American Society of Anesthesiologists (ASA) physical status classification system scores, type and duration of surgery, type and level of anesthesia, onset of erection, treatment characteristics and treatment outcome were recorded for each patient. Results The mean (SD) age was 68.3 years (range, 66.0–77.0 years). ASA physical status category I and II were noted in 55.6 and 44.4% of patients, respectively. All cases received spinal anesthesia (n = 9) at T8–10 dermatome levels, for TURP in 7 (77.8%) cases and for TURBT in 2 (22.2%) cases. The onset of penile erection was post-urethroscope in 7 (77.8%) cases. The average total ketamine dose was 34.3 mg (range, 18.0–75.0 mg). The average duration of the operation was 91.7 min (range, 40.0–140.0 min). Ketamine treatment resulted in resolved erection with delayed procedure in 7 (77.8%) cases, while conversion to general anesthesia was required in 2 (22.5%) cases. Conclusions In conclusion, the prevalence of intraoperative penile erection during spinal anesthesia for endourological surgery was 2.2% in our experience. These findings demonstrated that intravenous injection of ketamine is an effective and safe method for immediate resolution of intraoperative penile erection with a high success rate.
