Pudendal nerve block prior to inflatable penile prosthesis implantation: decreased intra-operative narcotic requirements.

The opioid epidemic has proven to be a public health crisis over the past two decades and efforts to decrease opioid exposure are sorely needed. Our objective was to determine whether pudendal nerve block utilization in the immediate pre-operative setting decreases intra-operative opioid analgesic requirements in veteran patients undergoing a primary inflatable penile prosthesis implantation. We performed a retrospective cohort analysis of all patients undergoing penile prosthesis implantation between January 2017 and July 2020 at the Charlie Norwood Veterans Affairs Medical Center in Augusta, GA. Univariable and multivariable gamma regression analyses were performed to evaluate the association between pudendal nerve block utilization and intra-operative opioid analgesic requirements. The study cohort consisted of 110 patients, 35 (31.8%) of whom underwent a pudendal nerve block. Median intra-operative opioid analgesic requirements were significantly lower in the pudendal nerve block group (16.3 versus 25.8 morphine milliequivalents, p = 0.037). Receipt of the nerve block was associated with significantly lower intra-operative opioid analgesic requirements on multivariable (coefficient 0.84, p = 0.038) regression analysis. There was no significant difference in post-operative opioid analgesic requirements (p = 0.18). In conclusion, pre-operative pudendal nerve blocks decrease intra-operative opioid analgesic requirements in veteran patients undergoing a primary inflatable penile prosthesis implantation.

Re-operation within 30 days of radical cystectomy: Identifying high-risk patients and complications using American College of Surgeons National Surgical Quality Improvement Program database.

INTRODUCTION: Radical cystectomy (RC) is a highly morbid procedure, with 30-day complication rates approaching 31%. Our objective was to determine risk factors for re-operation within 30 days following a RC for non-metastatic bladder cancer. METHODS: We included all patients who underwent a RC for non-metastatic bladder cancer using The American College of Surgeons National Surgical Quality Improvement Program database between January 1, 2007 and December 31, 2014. Logistic regression analyses were used to evaluate predictors of re-operation. RESULTS: A total of 2608 patients were included; 5.8% of patients underwent re-operation within 30 days. On multivariable analysis, increasing body mass index (BMI) (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.01-1.07), African American race (vs. Caucasian OR 2.29, 95% CI 1.21-4.34), and history of chronic obstructive pulmonary disease (COPD) (OR 2.33, 95% CI 1.45-3.74) were significant predictors of re-operation within 30 days of RC. Urinary diversion type (ileal conduit vs. continent) and history of chemotherapy or radiotherapy within 30 days prior to RC were not. Patients who underwent re-operation within this timeframe had a significantly higher mortality rate (4.0% vs. 1.6%) and were more likely to experience cardiac (7.2% vs. 1.9%), pulmonary (23.0% vs. 3.0%), neurological (2.0% vs. 0.49%), and venous thromboembolic events (10.5% vs. 5.4%), as well as infectious complications (64.5% vs. 24.1%), with a significantly longer hospital length of stay (16.5 vs. 7.0 days). CONCLUSIONS: Recognizing increasing BMI, COPD, and African American race as risk factors for re-operation within 30 days of RC will allow urologists to preoperatively identify such high-risk patients and prompt them to adopt more aggressive approaches to minimize postoperative surgical complications.
