We have previously reported the use of TRUS volume as a predictive tool for enucleation and operating room (OR) times. For the established surgeon TRUS volumes can optimize theatre utilization. We represent our predicted versus actual enucleation and OR times to generate validated charts to use as an accurate predictive tool to enhance theatre utilization. METHODS 393 HoLEPs were undertaken with a 50 Watt (W) holmium laser (Auriga XL, Boston Scientific Inc., Richard Wolf Piranha Morcellator) by two HoLEP naive surgeons during their learning curve and subsequently. All patients underwent a TRUS volume pre-operatively (B-K Hawk 2102). Accurate enucleation time and total operating room (OR) time for a given TRUS volume were plotted to use as a predictive tool to enhance operating list scheduling. Using the predicted enucleation times from a original cohort of 253 cases linear regression modelling was undertaken to validate predictive enucleation & OR times with the actual enucleation times for our last 100 cases. RESULTS Enucleation time and TRUS volume were plotted graphically for the 393 cases (blue shaded region) and compared to similar data previously plotted for our first 253 cases (red line). There was a clear improvement in enucleation and total operating room times indicating further improvement and accuracy in the predictive times for a given TRUS size as surgeon experience increases. This allows for the enhanced prediction of theatre time improving theatre utilization. CONCLUSIONS Validation of predictive TRUS volume graphs for enucleation time during HoLEP surgery can be used as a tool to enhance theatre utilization by individual surgeons. We recommend the use of this simple tool for units setting up a HoLEP service. © 2017FiguresReferencesRelatedDetails Volume 197Issue 4SApril 2017Page: e10-e11 Advertisement Copyright & Permissions© 2017MetricsAuthor Information Farooq Khan More articles by this author Mohamed Asad Saleemi More articles by this author Barney Barrass More articles by this author Sanjeev Taneja More articles by this author Asher Alam More articles by this author Aza Mohammed More articles by this author Ian Nunney More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
