Evaluation of the optimal duration for retrograde intrarenal stone surgery to prevent postoperative complications

Abstract

Objective To evaluate retrograde intrarenal surgery (RIRS) outcomes and to determine the effect of operative time on complications of RIRS. Methods Patients undergoing RIRS for renal stones were evaluated. These patients were divided into two groups according to the operation time (Group 1<60 minutes and Group 2>60 minutes). Peroperative outcomes such as fluoroscopy time, stone-free rates, complications and duration of hospitalization were compared. Results Group 1 consisted of 264 patients and Group 2 consisted of 297 patients. SFR rates, duration of hospitalization, and postoperative urinary tract infection rates were similar in both groups. Fluoroscopy time was 7.8±7.3 (0-49) sec in group 1 and 13.1±9.8 (0-81) sec in group 2. Complications according to modified Clavien–Dindo classification system (MCDCS) were 13 and 32 patients (Grade 1), 31 and 63 patients (Grade 2), 1 and 1 patient (Grade 3) in group 1 and 2, respectively. There was statistical difference between the two groups in terms of duration of fluoroscopy time and the MCDCS. Although duration of hospitalization and UTI rates were higher in group 2, no statistical significance was observed among groups. Conclusion Limiting the operation time to 60 minutes in RIRS seems to be important in reducing postoperative complications.

Retrograde Intrarenal Surgery Without JJ Stent Placement in Selected Cases of Renal Stones of 1 cm or Less Requirement of Ureteral Catheterization: Retrospective Observational Study

“…It has been mentioned in previous studies that the main factors determining the success and complications of the surgery are stone size, stone localization, duration of the procedure, difficult anatomy and comorbidities. [17][18][19] In our study, RIRS procedures that lasted less than 30 minutes in the middle and upper calyx stones 10 mm or less were evaluated. All patients were stone-free by using the dusting method.…”

Explaining the Elusive Nature of a Well-Defined Threshold for Blood Transfusion in Advanced Epithelial Ovarian Cancer Cytoreductive Surgery

“…Nevertheless, an extensive surgical approach is associated with increased blood loss and potentially higher peri-operative complications [20]. As studies continue to share knowledge about the optimal duration of surgical procedures [21], another study is currently underway to assign optimal procedural times based on knowledge retrieved from operative notes using natural language processing (data not shown). This focus holds potential implications including enhancing information delivery to surgeons to promote meticulous planning for complication reduction.…”

As studies continue to share knowledge about the optimal duration of surgical procedures [21], another study is currently underway to assign optimal procedural times from knowledge retrieved from operative notes using natural language processing (data not shown). This niche may have potential implications: to improve information delivery to surgeons so that careful planning is considered in reducing complications; secondly, it will improve patient counseling or discussion about extent of surgery or alternative therapeutic options.…”
