Bladder Stones in Renal Transplant Patients: Presentation, Management, and Follow-up.

INTRODUCTION: The study aim was to analyze the presentation, management, and follow-up of renal transplant patients developing bladder calculi. METHODS: Patients who underwent renal transplant with postoperative follow-up at our institution were retrospectively analyzed (1984-2023) to assess for the development of posttransplant bladder stones. All bladder stones were identified by computerized tomography imaging and stone size was measured using this imaging modality. RESULTS: The prevalence of bladder calculi post-renal transplantation during the study window was 0.22% (N = 20/8,835) with a median time to bladder stone diagnosis of 13 years posttransplant. Of all bladder stone patients, 6 (30%) received deceased donor and 14 (70%) living donor transplants. There were 11 patients with known bladder stone composition available; the most common being calcium oxalate (N = 6). Eleven (55%) patients had clinical signs or symptoms (most commonly microhematuria). Fourteen of the bladder stone cohort patients (70%) underwent treatment including cystolitholapaxy in 12 subjects. Of these 14 patients, 9 (64%) were found to have nonabsorbable suture used for their ureteroneocystostomy closure. CONCLUSIONS: The prevalence of bladder stones post-renal transplant is low. The utilization of nonabsorbable suture for ureteral implantation was the main risk factor identified in our series. This technique is no longer used at our institution. Other factors contributing to bladder stone formation in this population warrant identification.

Sport-Specific Increased Risk of Anterior Cruciate Ligament Injury Following a Concussion in Collegiate Female Lacrosse.

ABSTRACT: Poor neurocognitive performance has been associated with a greater risk of musculoskeletal injury, and anterior cruciate ligament (ACL) injury prevention protocols include exercises to improve neuromuscular control. Research shows that a concussion elevates the risk for subsequent lower-extremity injury, because concussions lead to lower neurocognitive performance. Studies have been conducted using data within individual male sports, such as football and rugby, or across collegiate sports in aggregate; no study has focused on women's sports. Using 7 years of data collected by athletic training staff at Davidson College, this paper evaluates preconcussive versus postconcussive lower-extremity injury risk across five collegiate women's sports: field hockey, soccer, basketball, volleyball, and lacrosse. Using incidence rate ratios, lacrosse athletes had a five-fold increase in ACL injury risk within 365 d following a concussion. Recognizing that postconcussive ACL tear risk varies across different women's sports is important in informing sport-specific concussion return to play protocols.

It's complicated: The relationship of non-narcotic medications and postoperative opioid use in radical cystectomy patients.

INTRODUCTION: The effect of individual non-narcotic analgesics in cystectomy enhanced recovery after surgery (ERAS) is unknown. Additionally, many non-narcotic medications are associated with side effects pertinent to the cystectomy population. To better understand the actual use and utility of these medications, we sought to characterize the association between non-narcotic medications and milligram morphine equivalent (MME) narcotic score during the postoperative inpatient stay. METHODS: We reviewed 260 consecutive ERAS cystectomy patients. The MME impact of non-narcotic compliance and cumulative dose of medication received was evaluated separately with general linear models. We also assessed relationship of non-narcotic compliance to patient reported pain score, length of stay (LOS), and time to return of bowel function (ROBF) and performed manual review of postoperative documentation to identify reasons for medication noncompliance. RESULTS: Compliance with postoperative acetaminophen, gabapentin, and ketorolac was low. There was an inverse relationship between ketorolac dose and MME on postoperative day 1 (-0.026 MME/mg; P = 0.004) and postoperative day 2 (-0.33 MME/mg; P < 0.001). Compliance with ketorolac was associated with lower MME on postoperative day 1 (26.1 MME v. 33.6 MME; P = 0.023). There were no such associations identified with gabapentin or acetaminophen. Gabapentin compliance was associated with earlier ROBF (3.7 days v. 4.3 days; P = 0.006). Ketorolac compliance was associated with lower pain score on POD1 (3.25 VAS v. 4.07 VAS; P = 0.019) and POD2 (3.05 VAS v. 3.85 VAS; P = 0.040) There was no association between medication compliance and LOS. The most common reasons identified for non-compliance with gabapentin and ketorolac were renal function concerns (38% and 40% respectively), bleeding concerns with ketorolac (20%) and concerns for neurologic adverse effect with gabapentin (16%). CONCLUSION: Compliance with non-narcotic medications in our ERAS cystectomy protocol was poor. There was a modest association with ketorolac and postoperative MME but no association with gabapentin or acetaminophen. Further study will clarify the role of these medications for cystectomy patients. Component specific analysis of protocolized care is valuable and may alter care pathways.

Impact of smoking status on health-related quality of life (HRQoL) in cancer survivors.

Introduction: The Health-Related Quality of Life (HRQoL) often declines among cancer survivors due to many factors. Some cancer patients who smoke before the cancer diagnosis continue this harmful habit, potentially contributing to a more significant decline in their HRQoL. Therefore, this study investigates the association between smoking status and HRQoL in cancer survivors. Methods: We conducted a cross-sectional study utilizing self-reported cancer history from 39,578 participants of the Behavioral Risk Factor Surveillance System (BRFSS) database, leveraging 2016 and 2020 year questionaries. A multidimensional composite outcome was created to assess HRQoL, integrating four distinct dimensions - general health, mental health, physical health, and activity limitations. After accounting for the complex survey design, logistic regression models were used to analyze the association between smoking status and poor HRQoL, adjusting for demographic, socioeconomic, and health-related confounders. Results: Our study found that, after adjusting for potential confounders, current smokers exhibited a significantly poorer HRQoL than never smokers (OR 1.65, 95%CI 1.40-1.93). Furthermore, former smokers showed a poorer HRQoL than never smokers; however, this association was not as strong as current smokers (OR 1.22, 95%CI 1.09-1.38). Conclusion: Our findings highlight the adverse association of smoking with poor HRQoL in cancer survivors, underscoring the importance of healthcare professionals prioritizing smoking cessation and providing tailored interventions to support this goal.

Impact of dedicated renal enhanced recovery after surgery (RERAS) program on postoperative opioid consumption and evaluation of surgeon-specific compliance to the program.

INTRODUCTION AND OBJECTIVE: Enhanced Recovery After Surgery (ERAS) protocols have been increasingly applied to urologic surgeries such as cystectomy and prostatectomy, though research defining protocols and outcomes for renal ERAS programs (RERAS) for nephrectomy remains limited. We aim to assess perioperative outcomes following implementation of our RERAS protocol modified from ERAS society cystectomy guidelines, as well as describe compliance with protocol guidelines. METHODS: We performed a retrospective cohort analysis of 400 patients who underwent partial or radical nephrectomy between October 2017 and August 2020. RERAS protocol was initiated September 30, 2018, and patients were categorized into pre- and post-RERAS implementation cohorts based on surgery date. Perioperative outcomes including complications, 30-day readmissions, length of stay, and opioid consumption were compared across pre- and post-RERAS cohorts. Protocol compliance was reported based on adherence to program recommendations. RESULTS: Among 400 patients included in analysis, the pre-RERAS cohort included 133 patients and the post-RERAS cohort included 267 patients. There were no differences in overall complications (P = 0.354) and 30-day readmissions (P = 0.078). Length of stay (P < 0.001) and postoperative opioid consumption (P < 0.001) were significantly reduced post-RERAS. We observed an increase in compliance with RERAS recommendations over time (P< 0.001). CONCLUSION: RERAS implementation was associated with decreased length of stay and opioid usage, underscoring the benefits of program adoption in an era of opioid dependence and strained hospital capacity. Successful initiation of a RERAS protocol requires intentional organization and buy in from all providers involved.
