Multicenter Study for the Effect of COVID-19 Lockdown on Patients With Sacral Neuromodulation Implants.

INTRODUCTION: The massive spread of COVID-19 affected many aspects of medical and surgical services. Many patients with sacral neuromodulation (SNM) devices needed integrated follow-up and close communication regarding the programming of the device. In this study, we aimed to explore the effect of COVID-19 lockdown on patients with SNM devices. MATERIALS AND METHODS: This was a multicenter study designed and conducted in four centers performing SNM (Toronto Western Hospital, Toronto, Canada; King Abdulaziz University Hospital, Jeddah, Saudi Arabia; Al-Amiri Hospital, Kuwait City, Kuwait; and Austin and Western Health, University of Melbourne, Australia). An online questionnaire was created through Google Forms and circulated among patients with SNM devices in all four mentioned centers. The questionnaire was sent to patients during the forced lockdown period in each country. RESULTS: A total of 162 responses were received by September 2020. Data showed that most patients had their device implanted before the lockdown period (92.5%, 150/162). Most patients did not experience any contact difficulties (91.9%, 149/162). When patients were requested for their preference of programming, 89.5% (145/162) preferred remote programming. Correlation analysis did not show any significant relation between patient diagnosis and COVID-19-related difficulties or preferences. CONCLUSION: The difficulties with access to care experienced during the pandemic and the patient's expressed willingness to participate in virtual care should provide impetus for manufacturers of SNM devices to move forward with developing remote programming capabilities.

Primary Bilateral High-Grade Vesicoureteral Reflux in Children: Management Perspective.

Objective Vesicoureteral reflux (VUR) is a common finding in the pediatric population with the risk of repeated infections and renal damage. There is little is known about the natural history of primary bilateral high-grade reflux. Herein we present our experience in the management of primary high-grade bilateral VUR and the long-term outcome of renal function in this specific group of patients. Materials and methods We retrospectively evaluated all patients with congenital bilateral VUR between 2006 and 2014. Records were reviewed for patient age at diagnosis, antenatal history, clinical presentation, the grade of VUR on voiding cystourethrogram (VCUG), presence of scars on dimercaptosuccinic acid (DMSA) scan, indications for surgical intervention, and surgical approaches. Clinical and radiological outcomes of this subgroup of patients were assessed. Results A total of 67 patients with bilateral VUR were identified, of whom 31 (20 boys and 11 girls) had primary high-grade (grade IV and V) bilateral VUR. The mean age at diagnosis was seven months. DMSA scans showed renal scars in 19 patients (61%) and eight of them were bilateral. Surgical intervention was necessary for 81% of patients with a success rate of 58% after endoscopic correction and 100% after reimplantation. Chronic kidney disease (CKD) developed in 13 patients (42%) after a mean follow-up of eight years. Conclusions Primary bilateral high-grade VUR carries a high rate of surgical intervention. The endoscopic correction has an acceptable success rate and efficient long-term outcome. Nevertheless, a significant proportion of patients progresses to CKD even after VUR management.
