Factors Predicting Operating Room Time in Ureteroscopy and Ureterorenoscopy

Abstract

Backgrounds/Aims: Operation room (OR) time is of great value affecting surgical outcome, complications and the daily surgical program with financial implications. Methods: We retrospectively evaluated 570 consecutive patients submitted to ureteroscopy or ureterorenoscopy for the treatment of ureteral or renal stones. Demographic parameters, patient's stones characteristics, type of ureteroscope, surgeon experience and surgical theater characteristics were analyzed. OR time was calculated from the initiation of anesthesia to patient extubation. Multivariate analysis was conducted using a linear regression test with multiple parameters to identify predictors of OR time. Results: Eight factors were identified as significant. These include total stones volume, ureteroscope used, stone number, nurses experience, radio-opacity of the stone on kidney-ureter-bladder X-ray, main surgeon experience, operating room type, and having a nephrostomy tube prior to surgery. Conclusions: The surgical team experience and familiarity with endourological procedure, and the surgical room characteristics has a crucial impact on OR time and effectiveness.

Retrograde intrarenal surgery with central neuraxial blockade versus general anesthesia: A systematic review and meta-analysis

“…For instance, Katafigiotis et al . [ 36 ] demonstrated that factors such as stone number, size, density, instrument type, surgeon experience, operating room setup, and prior nephrostomy tube use can independently affect operating time in RIRS. Given the diverse array of factors influencing this parameter, the observed high heterogeneity in the study, which continued even after subgroup studies, is not surprising.…”

Outcomes of Retrograde Intrarenal Surgery Performed Under Neuraxial vs. General Anesthesia: An Updated Systematic Review and Meta-Analysis

“…Indeed, operation time with RIRS can depend on several variables. In a recent study, Katafigiotis et al ( 36 ) have shown that stone number, dimension, density, the type of instrument, surgeon experience, type of operating room, and use of prior nephrostomy tube are independent factors that can influence operating time with RIRS. Considering a wide-ranging of factors influencing operating time, it was not surprising to note the high heterogeneity in the meta-analysis which persisted even after subgroup analyses.…”

Ergonomics and Surgeon Comfort During Flexible Ureteroscopy

“…A well-trained team inside the operation theatre is important to deliver efficient and safe FURS. 44 The operating surgeon, assistant surgeon, anaesthesiologist, surgical tech technician, circulating nurse, and occasionally- a medical device company representative, help the surgeon during the operation. But above all, good communication between the team is the key element in performing a flawless procedure.…”
