Background: It has been demonstrated that a single spinal anesthesia is insufficient to stop the activation of the obturator nerve and contraction of the adductor muscle. This can result in issues such bladder perforation during the transurethral resection of lateral wall bladder tumors (TURBT) performed under sutures. Many more strategies are still being researched to tackle this, with the inguinal strategy recently gaining popularity. The study's objective was to determine the frequency of jerks and muscular spasms following inguinal approach obturator nerve block in TURBT of lateral wall urinary bladder tumors under SA. Material & Methods: The Department of Anesthesiology inEra Medical College, Lucknow, India, was the site of this retrospective observational study. The study ran from January 2022 to July 2022 for a total of six months. Following inclusion and exclusion criteria, a total of 20 instances of transurethral resection of lateral wall bladder tumor (TURBT) had been included as the study population at this time. Results: Of the participants, 45% were between the ages of 60 and 69, 30% were between the ages of 50 and 59, 15% were between the ages of 70 and 79, and 10% were 80 years of age or older. Seventy percent of the individuals had hypertension, making it the most prevalent comorbidity. Notable health conditions were diabetes (45%), chronic renal disease (15%), chronic obstructive pulmonary disease (15%), heart disease (10%), and benign prostatic enlargement (15%). Most patients experienced no jerk at all during TURBT, 10% had minor jerk, and 1 patient had maximum jerk. Twenty percent of patients thought their end condition was great during the 24-hour follow-up, and sixty percent had regraded their result as good. Of the patients, just one thought their result was unsatisfactory, and fifteen percent did not have follow-up data available. Conclusion: Following the use of the inguinal route, the study found a very low incidence of muscular spasm or jerk during TURBT. The majority of the patients had favorable short-term outcomes, according to the study.
