The effect of sugammadex on postoperative urinary retention post-laparoscopic and robotic hysterectomy with and without concomitant procedures.

INTRODUCTION AND HYPOTHESIS: This study was aimed at determining the effect of sugammadex versus a combination of glycopyrrolate and neostigmine (GN) for neuromuscular reversal blockage on transient postoperative urinary retention (TPOUR) in patients undergoing a laparoscopic and robot-assisted laparoscopic hysterectomy. METHODS: We conducted a retrospective cohort study in patients undergoing a laparoscopic or robotic hysterectomy between February 2017 and December 2021. Patients with and without concomitant procedures were included. Demographics and perioperative data were extracted from the patient's medical record. Before discharge, all patients were required to spontaneously void and have a post-void residual of less than 150 ml. RESULTS: We identified 500 patients and 485 were included in the final analysis. We had 319 subjects who received sugammadex and 166 GN combination. Both groups had overall similar demographics and perioperative characteristics. Most patients had a conventional laparoscopy procedure (391 [82.5%]) compared with robotic (83 [17.5%]). Patients who received GN were significantly more likely to be discharged home with an indwelling catheter (odds ratio [OR], 1.82; 95% confidence interval [CI], 1.09-3.05). After adjusting for perioperative medications and sling implantation during the surgery a logistic regression model continued to demonstrate that patients who received GN had significantly higher odds of being discharged with a catheter (OR, 1.79; 95% CI, 1.03-3.12). CONCLUSIONS: Our findings suggest that sugammadex decreases the odds of TPOUR after laparoscopic hysterectomies with and without slings compared with the combination of GN. Additional prospective trials are required to confirm this finding.

Postoperative Urinary Retention.

ABSTRACT: This clinical consensus statement on the management of postoperative (<6 weeks) urinary retention (POUR) reflects statements drafted by content experts from the American Urogynecologic Society's POUR writing group. The writing group used a modified Delphi process to evaluate statements developed from a structured literature search and assessed for consensus. After the definition of POUR was established, a total of 37 statements were assessed in the following 6 categories: (1) incidence of POUR, (2) medications, (3) patient factors, (4) surgical factors, (5) urodynamic testing, and (6) voiding trials. Of the 37 original statements, 34 reached consensus and 3 were omitted.

Development and validation across trimester of the Prenatal Eating Behaviors Screening tool.

Rapid screening tools are useful for identifying at-risk patients and referring them for further assessment and treatment, but none exist that consider the unique medical needs of pregnant women with eating disorders (EDs). There is a need for a rapid, sensitive, and specific screening tool that can be used to identify a potential ED in pregnancy. We started with a set of 25 questions, developed from our qualitative work along with other ED screening tools, and tested on a development (n = 190) and validation sample (n = 167). Statistical analysis included factor analysis and logistic regressions with ROC curves. Development and validation samples were combined for trimester analysis (n = 357). Refining the tool to 12 items demonstrated strong internal reliability (development alpha = 0.95, validation alpha = 0.91). With correlated errors, questions demonstrated acceptable CFA fit (development: GFI: 0.91, RMSEA: 0.10, NNFI: 0.95; validation: GFI: 0.85, RMSEA: 0.14, NNFI: 0.86). Similar fits were seen by trimester: first trimester n = 127, GFI: 0.89, RMSEA: 0.12, NNFI: 0.94; second trimester n = 150, GFI: 0.83, RMSEA: 0.14, NNFI: 0.88; third trimester n = 80, GFI: 0.99, NNFI: 0.99. Validation against current ED diagnosis demonstrated acceptable sensitivity and specificity using a cutoff of 39 (development sensitivity = 80.7%, specificity = 79.7%, OR = 16.42, 95% CI: 7.51, 35.88; validation sensitivity = 69.2%, specificity = 86.5%, OR: 17.43, 95% CI: 6.46, 47.01). Findings suggest the PEBS tool can reliably and sensitively detect EDs across pregnancy trimesters with 12 questions. A further implication of this work is to reduce health and mental health treatment disparities through this standard and rapid screening measure to ensure early identification and treatment.

Evaluation of Uroflowmetry Curve Patterns and Nomogram Construct in Healthy Nulliparous Female Adults.

OBJECTIVE: The aims of the study were to construct uroflowmetry nomograms, evaluate uroflowmetry flow rate patterns, and graphically illustrate overlaid uroflowmetry curves in nulliparous female adult volunteers. METHODS: We performed a prospective cross-sectional study evaluating uroflowmetry curve and flow rate patterns on a cohort of nulliparous female adult volunteers. Primary outcome was construction of uroflowmetry maximum and average flow rate nomograms. Secondary outcomes included evaluation of uroflowmetry flow rate patterns and graphical illustrations of overlaid uroflowmetry curves. Uroflowmetry printouts were overlaid and used to create a model of uroflow patterns, and nomogram curves were analyzed in 5 groups based on voided volumes. RESULTS: We enrolled 164 participants and 158 had voided volumes between 50 mL and 800 mL. Participants' mean age and body mass index were 25 years and 23, respectively. Maximum and average flow rate nomograms were created, and analysis of uroflow parameters was performed. Median voided volume was 241 mL (149-431 mL), the median maximum flow was 29 mL/s (20-38 mL/s), and the median average flow was 15 mL/s (10-19 mL/s). Participants were divided into 5 groups based on voided volumes. The nomogram patterns for each voided volume group were visually different from typical nomogram patterns. CONCLUSIONS: Uroflowmetry curves and flow rates vary significantly according to voided volume. Our study suggests that in normal healthy nulliparous female adults there is likely a broader range of normal flow rates and uroflowmetry curves than what has been previously reported. Further research is needed to investigate the accuracy of these finding.

Post-partum rectus sheath hematoma complication: case report.

Pregnancy, surgery, and trauma are known risk factors for the development of rectus sheath hematomas (RSHs). The exact incidence of RSH during pregnancy is unknown, however this disease carries a risk of complication and even mortality. The role of infection in this condition is less known with only a few reported case studies in medical literature. In our case a 26-year-old G4P2113 1-month status post cesarean section presented with 2 weeks of progressive lower abdominal pain after her 50-pound daughter jumped on her. Upon further work up a computed tomography (CT) scan found a 15-cm RSH. Expectant management is the recommended first line of treatment, however, this failed after the patient presented with signs and symptoms of infection. An exploratory laparotomy was performed that had evidence of necrotizing fasciitis of the rectus muscle and subcutaneous tissue. This is a very atypical presentation of a RSH complicated with myonecrosis after a cesarean delivery. Review of the medical literature shows appropriate work up and diagnosis of RSH in pregnant patients is critical for early intervention. Furthermore, while conservative treatment is typically appropriate for non-pregnant patients it may not be sufficient for pregnant and post-partum patients. Improved understanding of this condition will result in heightened clinical suspicion, faster intervention, and more appropriate treatment. This is critical to reducing the maternal and perinatal morbidity/mortality associated with this disease.

Knot integrity using different suture types and different knot-tying techniques for reconstructive pelvic floor procedures.

INTRODUCTION AND HYPOTHESIS: Surgeons use a variety of sutures and knot-tying methods during pelvic reconstructive procedures. We hypothesized that knot-strength integrity will be similar with regards to type of knot, type of suture, and the knot-tying process. METHODS: Using six different suture materials, flat square knots and slip knots were tied robotically and by hand by two surgeons. Knot integrity was evaluated using an Instron 5544 machine. We measured force and elongation at suture failure or knot slippage (whichever came first) as well as force at 3-mm displacement. RESULTS: Four hundred and thirty-two knots were tie; one unraveled before the analysis, and 431 were tested. Three hundred and ninety-two knots reached or surpassed tensile strength of 30 N, the force at which tissue itself will fail. Knots tied with polyglyconate suture achieved the greatest tensile strength and those with OO-polydioxanone had the lowest. Hand-tied knots, regardless of technique and suture material, had greater tensile strength but greater elongation than robotically tied knots. Slip knots and flat square knots have similar integrity regardless of the tying technique. CONCLUSION: Hand-tied knots had greater tensile strength than robotic knots, but the strength to break all knots required supraphysiological conditions. The decision to use a specific type of suture based on strength is not supported by our results, suggesting that surgeons may choose sutures based on other characteristics and personal comfort.

Vascular anatomical relationships of the retropubic space and the sacrospinous ligament, using three-dimensional imaging.

INTRODUCTION AND HYPOTHESIS: Pelvic anatomy is complex and intimate knowledge of variabilities in anatomical relationships is critical for surgeons to safely perform surgical procedures. Three-dimensional Imaging provides the opportunity to analyze undisturbed anatomical relationships. The authors hypothesized that three-dimensional models created from pelvic computed tomography angiograms could be used to obtain vascular anatomical measurements, and that the measurements obtained from three-dimensional models would be similar to those from cadaver studies. METHODS: We included all pelvic computed tomography angiograms that were acquired in female patients older than 18 years at our institution within the previous 5 years. Three-dimensional models were created using the Invivo5 software based on the Digital Imaging and Communications in Medicine files. Structures of interest were virtually dissected and measured replicating previous cadaver studies. Statistical analysis of demographics and measurements was performed. RESULTS: The final analysis included 87 studies. The average age of the subjects was 66.9 years and their average BMI was 26.1 kg/m2. Of the 87 subjects, 12.6% had a history of hysterectomy, 2.3% a history of a continence procedure, and 1.1% a history of a prolapse procedure. The range of distance between the ischial spine and the pudendal artery was 3-17 mm. The closest vessels to the lower edge of the symphysis pubis were the obturator vessels. The aberrant corona mortis vessel was present in 27.9% of the subjects. Prior hysterectomy was associated with changes in the measurements of the obturator arteries with minimal changes in other measurements. CONCLUSIONS: Our results indicate that this technology provides similar measurements to those found in previous unembalmed cadaver studies. This technology offers a great opportunity to study anatomical relationships in a native undisturbed state.

A Randomized Controlled Trial of Patient-Controlled Valve Catheter and Indwelling Foley Catheter for Short-term Bladder Drainage.

OBJECTIVE: The purpose of this study was to compare catheter-related pain and quality-of-life scores between 2 catheters used after failed voiding trials following urogynecologic surgery. METHODS: Women failing an inpatient voiding trial requiring short-term catheterization after urogynecologic surgery were randomized to receive either a standard FC or a patient-controlled VC. Subjects completed a 6-item, visual analog scale-based postoperative questionnaire (POQ) and an outpatient voiding trial 3 to 7 days after surgery. Baseline demographic, surgical data, and results of the outpatient voiding trial were recorded. The primary outcome was the difference in mean score for catheter-related pain on the POQ, based on intent to treat. Secondary outcomes included between-group differences in means for individual POQ items and a calculated composite satisfaction score. The statistician was blinded to group assignment. RESULTS: Forty-nine subjects were randomized to FC (n = 24) and VC (n = 25). Two subjects, one in each group, were excluded from the primary analysis because of missing data. Mean age was 60.6 (SD, 12.5) years. Baseline characteristics were similar. Valve catheter users had a lower median catheter-related pain score (1.25 vs 2.3), but not significantly (P = 0.153). Valve catheter users had significantly lower median scores for frustration (1.2 vs 3.8; P = 0.018) and limitation on social activities (0 vs 7.6; P < 0.001). Mean composite satisfaction score was statistically significantly lower for the VC group (2.23 [SD, 1.83] vs 3.62 [SD, 1.95]; P < 0.01), suggesting greater satisfaction. CONCLUSIONS: Valve catheter and FC users report similar catheter-related pain. Valve catheter users scored better in overall satisfaction, frustration, and limitations on social activities.

Compliance with follow-up in an inner-city population treated with intramuscular methotrexate for suspected ectopic pregnancy.

OBJECTIVE: To evaluate compliance with follow-up among inner-city patients with ectopic pregnancy treated with methotrexate, in addition to assessing outcome. METHODS: Retrospective analysis of all patients evaluated for first-trimester bleeding and diagnosed with ectopic pregnancy at the Bronx Lebanon Hospital Center, New York, USA, from October 2007 to March 2011. Compliance and complications were evaluated for all patients who received medical treatment with methotrexate. RESULTS: Ninety-nine patients with hemodynamically stable ectopic pregnancies were identified. Therapy with methotrexate was effective in 87 (87.9%) cases. Only 10 (10.1%) patients were fully compliant during follow-up after methotrexate administration. There were no differences according to ethnicity. Number of follow-up visits after treatment significantly affected compliance. CONCLUSION: Improvements in selection criteria for therapy and simplification of follow-up for patients with medically managed ectopic pregnancy are required.
