Study Objective To present a series of robotic laparoendoscopic single-site surgery (LESS) and reduced-port hysterectomy cases and discuss the surgical technique required for successful use on this new platform. Design Retrospective case series. Setting Academic medical center. Patients All patients undergoing robotic LESS or reduced-port hysterectomy with the SP1098 da Vinci SP Surgical System (Intuitive Surgical, Sunnyvale, CA) from December 2019 to March 2020. Interventions Robotic LESS or reduced-port hysterectomy. Measurements and Main Results A total of 8 cases of hysterectomy were performed successfully. Four cases included concomitant resection of endometriosis. Five cases required placement of an additional port. The average uterine weight was 136.1 g ± 61.5 g (range 87–246). The average estimated blood loss was 37.5 mL ± 27 mL (range 20–100). The average operative time was 86.5 minutes ± 27.1 minutes (range 60–132). The time required for vaginal cuff closure was available for patients 5 to 8, and ranged from 10 minutes to 13 minutes. All patients had same-day discharge. There were no conversions to alternative surgical modality, complications, or readmissions. Conclusion Our preliminary experience with the SP1098 da Vinci SP Surgical System demonstrated the technical feasibility and safety of this surgical modality for gynecologic surgery. Additional studies examining postoperative outcomes and prospective studies comparing this modality with traditional robotic surgery are indicated.

Study Objective: Surgeons employ various methods for evaluating what is considered a common occurrence after gynecologic operations, postoperative urinary retention (POUR). Few have reported the incidence of POUR with a liberal voiding protocol (no requirement to void before discharge). The primary objective of this study was to evaluate the risk of POUR after benign gynecologic surgery, comparing a liberal voiding protocol with more strict voiding protocols. Secondary outcomes included length of hospital stay (LOS) and urinary tract infection (UTI). Design: Retrospective cohort study. Setting: Quaternary-care academic hospital in the United States. Patients: Patients undergoing hysterectomy or myomectomy at Cedars-Sinai Medical Center from August 2017 through July 2018 (n = 652). Cases involving incontinence operations, correction of pelvic organ prolapse, malignancy, or peripartum hysterectomy were excluded. Interventions: Hysterectomy, myomectomy. Measurements and Main Results: POUR, defined as the need for recatheterization within 24 hours of catheter removal, along with UTI and LOS were compared between liberal and strict voiding protocols. A subgroup analysis was performed for those undergoing minimally invasive surgery (MIS). A total of 303 (46.5%) women underwent surgery with a liberal postoperative voiding protocol and 349 (53.5%) women with a strict voiding protocol. Overall, the incidence of POUR was low at 3.8% and not different between the groups (2.6% liberal vs. 4.9% strict, p = .14). UTIs also occurred infrequently (2.8% overall, 2.6% liberal vs. 2.9% strict, p = .86). Similar results were seen specifically among those who underwent MIS: POUR (3.7% overall, 2.8% liberal vs. 5.3% strict, p = .17) and UTI (3.3% overall, 2.4% liberal vs. 4.7% strict, p = .28). The median LOS (interquartile range) was much shorter for MIS patients with a liberal voiding protocol (median 15 hours overall [interquartile range 15 hours], 9 [4] hours liberal vs. 36 [34] hours strict, p <.01). Among those discharged the same day (72.6% of the MIS cases), patients with a liberal voiding protocol had a significantly shorter LOS than those with strict (mean [standard deviation] 9.4 [2.5] hours vs. 10.6 [35] hours, p <.01). Postoperative complications occurred less frequently in those with MIS procedures (11.8% in MIS vs. 20.2% in laparotomies, p <.01) and those with liberal voiding protocols (11.2% liberal vs. 16.9% strict p = .04). Conclusion: Overall, POUR occurs infrequently after major benign gynecologic surgery and does not differ between those with liberal and strict voiding protocols. Our data suggest that same-day discharge after MIS hysterectomy and myomectomy without a requirement to void does not increase the risk of POUR and shortens LOS.

Study objective: Compare the rates of urinary retention in patients undergoing endoscopic hysterectomy with those of patients undergoing nonhysterectomy endoscopic gynecologic surgery. Design: Retrospective case control study matched by operative time. Setting: Academic medical center. Patients: All patients undergoing endoscopic gynecologic surgeries between January 2013 and December 2018. Interventions: Outpatient endoscopic gynecologic surgery.Measurements and Main Results: A total of 200 endoscopic hysterectomy cases were matched to endoscopic nonhysterectomy gynecologic surgery controls in a 1:1 ratio. The differences in baseline and operative characteristics between the 2 groups included age (48.6 years vs 45.7 years, p = .04), perioperative opioid administration (morphine milligram equivalents, 11.6 mg vs 7.6 mg, p = .01), and estimated blood loss (64.1 mL vs 31.8 mL, p = .001). The rate of urinary retention in the hysterectomy group was double that in the nonhysterectomy group (26.5% vs 13%, p = .01). In the hysterectomy group, age, perioperative opioids, operative time, and estimated blood loss did not differ between those who failed and those who passed the void trial. In the nonhysterectomy group, only operative time was significantly longer in those who failed the void trial (108 minutes vs 94.3 minutes, p = .04). After adjusting for perioperative opioid use and operative time, the relative risk of urinary retention in the hysterectomy group was 2.3 (p = .002, 95% confidence interval, 1.38−3.98). Conclusion: Hysterectomy appears to be an independent and major factor contributing to postoperative urinary retention. When compared with nonhysterectomy gynecologic surgical controls with similar operative times, the rate of urinary retention in patients who underwent hysterectomy was doubled.

Purpose of review The United States has the highest healthcare costs among developed countries. This review evaluates surgical practices and equipment choices during endoscopic hysterectomy, highlighting opportunities for the gynecologic surgeon to reduce costs and maximize surgical efficiency. Recent findings There are opportunities to economize at every step of the endoscopic hysterectomy. When surgeons are provided education about instrumentation costs, the cost of hysterectomy has been shown to decrease. Colpotomy has been found to be the rate-limiting step in laparoscopic hysterectomy; use of a uterine manipulator likely saves time and money. When evaluating the economic impact of route of surgery, the cost differential between laparoscopic and robotic-assisted hysterectomy has decreased. Robotic-assisted hysterectomy may be more cost-effective in some cases, such as for larger uteri. From a systems-level perspective, dedicating a specific operating room team to the gynecology service can decrease operative time. Summary The gynecologic surgeon is best equipped to control surgery-related costs by making choices that improve surgical efficiency and decrease operating room time. If a costlier piece of equipment leads to a more efficient case, the choice may be more cost-effective. There are multiple systems-level changes that can be implemented to decrease surgery-related costs.
