Filter by:To compare the efficacy of ultrasound-guided erector spinae plane block versus ultrasound-guided paravertebral block in pediatric patients undergoing percutaneous nephrolithotomy
Surgical simulation provides opportunities for surgeons to practice specific skills, prior to performing complex tasks on patients, with the goal of reducing potential errors and providing a safer procedure for the patient. The investigators will use a novel approach to simulation (patient-specific rehearsals) i.e., practice a short time prior to the live event that uses gel models of organs created by a 3D printer, and that are specific to each patient versus models that represent an ideal training model. The investigators' overarching goals are to improve patient outcomes by developing the best platform for surgeons to efficiently enhance performance prior to live surgery.
The purpose of the study is to assess and compare the efficacy and morbidity standard percutaneous nephrolithotomy with tubeless PNL. A total of approximately 60 patients will be enrolled. Patients will be randomized to one of four groups: standard percutaneous nephrostomy, double-J ureteral stent, open-ended ureteral catheter and no nephrostomy or ureteral stent/catheter. Primary Outcome Measures will include length of procedure and estimated blood loss. Post-operative analgesic use (both parenteral and oral), pain scores, time to ambulation, time to oral intake, and pain scores will also be recorded. Time to nephrostomy tube removal, external ureteral and Foley catheter removal and patient discharge from the hospital will also be recorded. Incidence and type of post-operative complications will also be recorded.
