Analgesia Using Transcutaneous Electric Nerve Stimulation in Office Bladder Chemodenervation, a Randomized Controlled Trial.

IMPORTANCE: Office bladder chemodenervation, performed via cystoscopy with intradetrusor onabotulinumtoxinA (BOTOX) injections, is a common treatment for overactive bladder/urge urinary incontinence. Transcutaneous electric nerve stimulation (TENS) has shown to provide analgesia during office hysteroscopy. Adjuvant analgesia using TENS during bladder chemodenervation has not been studied. OBJECTIVE: The primary outcome is a clinically significant (10-mm) difference in pain visual analog scale (VAS) measurements during injections for chemodenervation using active TENS compared with placebo TENS. We hypothesize that active TENS use will significantly change pain VAS scores. Secondary outcomes include 5-point pain Likert scale, satisfaction 10-point scale, and adverse events. STUDY DESIGN: This was a double-blind randomized control trial of men and women with urinary urge incontinence undergoing office chemodenervation performed in an academic and private setting. Participants were randomized into 2 groups: chemodenervation with active TENS or placebo TENS. Power calculation determined 100 patients would be required detect a difference of 10 mm on pain VAS. RESULTS: One hundred one (85 female and 16 male) participants were recruited. No differences were noted in the demographics. Participants in the active TENS group reported a difference of greater than 10 mm in pain VAS scores (48 ± 23 vs 31 ± 23, P = 0.01). Satisfaction index scores were high but no difference was noted between groups (8.6 vs 8.7, P = 0.68). CONCLUSIONS: Most participants were eligible to use TENS units. Transcutaneous electric nerve stimulation is a safe and noninvasive adjuvant analgesia option for patients undergoing this procedure. Lower pain levels and high satisfaction rates suggest that this is an additional analgesic option during outpatient chemodenervation.

The prevalence of hyperglycemia and its association with perioperative outcomes in gynecologic surgery: a retrospective cohort study.

BACKGROUND: Preoperative hyperglycemia has been associated with perioperative morbidity in general surgery patients. Additionally, preoperative hyperglycemia may indicate underlying impaired glucose metabolism. Thus, identification of preoperative hyperglycemia may provide an opportunity to mitigate both short-term surgical and long-term health risk. We aimed to study this phenomenon specifically in the gynecologic surgery population. Specifically, we aimed to evaluate the association between preoperative hyperglycemia and perioperative complications in gynecologic surgery patients and to characterize adherence to diabetes screening guidelines. METHODS: This retrospective cohort study included 913 women undergoing major gynecologic surgery on an enhanced recovery pathway from January 2018 to July 2019. The main exposure was day of surgery glucose ≥ 140 g/dL. Multivariate regression identified risk factors for hyperglycemia and composite and wound-specific complications. RESULTS: Sixty-seven (7.3%) patients were hyperglycemic. Diabetes (aOR 24.0, 95% CI 12.3-46.9, P < .001) and malignancy (aOR 2.3, 95% CI 1.2-4.5, P = .01) were associated with hyperglycemia. Hyperglycemia was not associated with increased odds of composite perioperative (aOR 1.3, 95% CI 0.7-2.4, P = 0.49) or wound-specific complications (aOR 1.1, 95% CI 0.7-1.5, P = 0.76). Of nondiabetic patients, 391/779 (50%) met the USPSTF criteria for diabetes screening; 117 (30%) had documented screening in the preceding 3 years. Of the 274 unscreened patients, 94 (34%) had day of surgery glucose levels suggestive of impaired glucose metabolism (glucose ≥ 100 g/dL). CONCLUSION: In our study cohort, the prevalence of hyperglycemia was low and was not associated with higher risk of composite or wound-specific complications. However, adherence to diabetes screening guidelines was poor. Future studies should aim to develop a preoperative blood glucose testing strategy that balances the low utility of universal glucose screening with the benefit of diagnosing impaired glucose metabolism in at-risk individuals.

Success of Concomitant Versus Interval Slings for Prevention and Treatment of Bothersome de Novo Stress Urinary Incontinence.

BACKGROUND: Despite large trials designed to guide management on whether to perform a prophylactic continence procedure at the time of pelvic organ prolapse (POP) repair, it remains unclear if a staged or interval approach confers advantages in treatment of bothersome stress urinary incontinence (SUI) in women without bothersome SUI before their POP repair. OBJECTIVE: The objective of this study was to compare success of concomitant versus interval slings for the prevention/treatment of de novo bothersome SUI after POP repair. STUDY DESIGN: This multicenter retrospective cohort with prospective follow-up enrolled women with minimal or no SUI symptoms who underwent minimally invasive apical surgery for stage 2 or higher POP between 2011 and 2018 and had a concomitant sling placed at the time of POP surgery or an interval sling placed. Prospectively, all patients were administered the Urogenital Distress Inventory Short-Form 6, the Patient Global Impression of Improvement, and questions on reoperation/retreatment and complications. RESULTS: A total of 120 patients had concomitant slings, and 60 had interval slings. There were no differences in the proportion of patients who had intrinsic sphincter deficiency (22% vs 20%), although the concomitant sling group was more likely to have a positive cough stress test result (30% vs 8%, P = 0.006). The interval sling group was more likely to report "yes" to SUI symptoms on Urogenital Distress Inventory Short-Form 6 (3% vs 30%, P = 0.0006) and during their postoperative visit (0% vs 24%, P < 0.0001). There were no differences in surgical complications. CONCLUSIONS: Among women with minimal or no SUI symptoms undergoing prolapse repair, concomitant slings resulted in lower rates of bothersome SUI compared with similar women undergoing interval sling placement.

Sacral neuromodulation for symptomatic chronic urinary retention in females: do age and comorbidities make a difference?

OBJECTIVES: To evaluate if age and medical comorbidities are associated with progression to implantation of sacral neuromodulation devices in women with symptomatic chronic urinary retention. METHODS: This multisite retrospective cohort included women with symptomatic chronic urinary retention who had a trial phase of sacral neuromodulation. The primary outcome was progression to implantation. Post-implantation outcomes were assessed as stable response versus decreased efficacy. A sub-analysis of catheter-reliant (intermittent-self catheterization or indwelling) patients was performed. Age was analyzed by 10-year units (decades of age). Multivariate logistic regression determined odds ratios for outcomes of implantation and for post-implantation stable response. RESULTS: Implantation occurred in 86% (243/284) women across six academic institutions. Most patients (160/243, 66%) were catheter reliant at the time of trial phase. Increased decade of age was associated with reduced implantation in all women [OR 0.54 (95% CI 0.42, 0.70)] and in the subgroup of catheter-reliant women [OR 0.52 (95% CI 0.37, 0.73)]. Post-implantation stable response occurred in 68% (193/243) of women at median follow-up of 2 years (range 0.3-15 years). Medical comorbidities present at the time of trials did not impact progression to implantation or post-implantation success. CONCLUSIONS: Increasing decade of age is associated with reduced implantation in women with symptomatic chronic urinary retention. There is no age cutoff at which outcomes change. Post-implantation stable response was not associated with age or medical comorbidities.

Sacral neuromodulation for overactive bladder in women: do age and comorbidities make a difference?

OBJECTIVE: To evaluate if age and comorbidities are associated with progression from trial phase to implantation of an implantable pulse generator in women with overactive bladder. METHODS: This multisite retrospective cohort included women with overactive bladder with or without urinary incontinence who had a trial phase for sacral neuromodulation. The primary outcome was progression to implantation. A sub-analysis of implanted patients was performed for the outcome of additional therapies or "implant only" for the duration of follow-up. Multivariate logistic regression models including potential predictors of implantation and post-implantation addition of therapies were performed. RESULTS: At six academic institutions, 91% (785/864) of patients progressed to implantation. Post-implantation success was achieved by 69% (536/782) of patients at median follow-up of 2 (range 0.3 to 15) years. Odds of implantation [OR 0.73 (CI 0.61, 0.88)] and post-implantation success [OR 0.78 (CI 0.98, 0.97)] were lower with increasing decades of age. Medical comorbidities evaluated did not affect implantation rates or post-implant success. CONCLUSIONS: Most women have successful sacral neuromodulation trials despite older age and comorbidities. Higher decade of age has a negative effect on odds of implantation and is associated with addition of therapies post-implantation. Comorbidities assessed in this study did not affect implantation or addition of therapies post-implantation. Most women add therapies to improve efficacy post-implantation, and explantation rates are low.

Prolapse of Colonic Neovagina After Vaginoplasty for Childhood Rhabdomyosarcoma Treated With Modified Altemeier Procedure.

We present the case of a patient with recurrent sigmoid neovaginal prolapse treated with a modified Altemeier procedure for rectal prolapse, which has not been previously described in the literature.Our case highlights the difficulty in treating patients with intestinal neovaginal prolapse due to their complex abdominal surgical history, altered anatomy, and goals of care.

A multicenter retrospective cohort study comparing urethral diverticulectomy with and without pubovaginal sling.

BACKGROUND: Urethral diverticulum is a rare entity and requires a high suspicion for diagnosis based on symptoms and physical exam with confirmation by imaging. A common presenting symptom is stress urinary incontinence (SUI). The recommended treatment is surgical excision with urethral diverticulectomy. Postoperatively, approximately 37% of patients may have persistent and 16% may have de novo SUI. An autologous fascial pubovaginal sling (PVS) placed at the time of urethral diverticulectomy (UD) has the potential to prevent and treat postoperative SUI. However, little has been published about the safety and efficacy of a concomitant pubovaginal sling. OBJECTIVE: The objective of this study was to compare the clinical presentation, outcomes, complications, and diverticulum recurrence rates in women who underwent a urethral diverticulectomy with vs without a concurrent pubovaginal sling. STUDY DESIGN: This multicenter, retrospective cohort study included women who underwent a urethral diverticulectomy between January 1, 2000, and December 31, 2016. Study participants were identified by Current Procedure Terminology codes, and their records were reviewed for demographics, medical or surgical history, symptoms, preoperative testing, concomitant surgeries, and postoperative outcomes. Symptoms, recurrence rates, and complications were compared between women with and without a concomitant pubovaginal sling. The primary outcome was the presence of postoperative stress urinary incontinence symptoms. Based on a stress urinary incontinence rate of 50% with no pubovaginal sling and 10% with a pubovaginal sling, we needed a sample size of 141 participants who underwent diverticulectomy without a pubovaginal sling and 8 participants with a pubovaginal sling to achieve 83% power with P<.05. RESULTS: We identified 485 diverticulectomy cases from 11 institutions who met the inclusion criteria; of these, 96 (19.7%) cases had a concomitant pubovaginal sling. Women with a pubovaginal sling were older than those without a pubovaginal sling (53 years vs 46 years; P<.001), and a greater number of women with pubovaginal sling had undergone diverticulectomy previously (31% vs 8%; P<.001). Postoperative follow-up period (14.6±26.9 months) was similar between the groups. The pubovaginal sling group had greater preoperative stress urinary incontinence (71% vs 33%; P<.0001), dysuria (47% vs 30%; P=.002), and recurrent urinary tract infection (49% vs 33%; P=.004). The addition of a pubovaginal sling at the time of diverticulectomy significantly improved the odds of stress urinary incontinence resolution after adjusting for prior diverticulectomy, prior incontinence surgery, age, race, and parity (adjusted odds ratio, 2.27; 95% confidence interval, 1.02-5.03; P=.043). It was not significantly protective against de novo stress urinary incontinence (adjusted odds ratio, 0.86; 95% confidence interval, 0.25-2.92; P=.807). Concomitant pubovaginal sling increased the odds of postoperative short-term (<6 weeks) urinary retention (adjusted odds ratio, 2.5; 95% confidence interval, 1.04-6.22; P=.039) and long-term urinary retention (>6 weeks) (adjusted odds ratio, 6.98; 95% confidence interval, 2.20-22.11; P=.001), as well as recurrent urinary tract infections (adjusted odds ratio, 3.27; 95% confidence interval, 1.26-7.76; P=.013). There was no significant risk to develop a de novo overactive bladder (adjusted odds ratio, 1.48; 95% confidence interval, 0.56-3.91; P=.423) or urgency urinary incontinence (adjusted odds ratio, 1.47; 95% confidence interval, 0.71-3.06; P=.30). A concomitant pubovaginal sling was not protective against a recurrent diverticulum (adjusted odds ratio, 1.38; 95% confidence interval, 0.67-2.82; P=.374). Overall, the diverticulum recurrence rate was 10.1% and did not differ between the groups. CONCLUSION: This large retrospective cohort study demonstrated a greater resolution of stress urinary incontinence with the addition of a pubovaginal sling at the time of a urethral diverticulectomy. There was a considerable risk of postoperative urinary retention and recurrent urinary tract infections in the pubovaginal sling group.

Compliance and outcomes after implementation of an enhanced recovery surgical protocol in older women undergoing pelvic reconstructive surgery.

The aim of this study is to evaluate compliance and outcomes with implementation of an enhanced recovery surgical protocol in older women undergoing pelvic reconstructive surgery. This is a retrospective cohort study of women undergoing pelvic reconstructive surgery after implementation of the pathway over a 12-month period. Overall compliance was defined as a categorial variable requiring adherence to all of the selected bundle components in patients <65 years old compared to those ≥65. Intraoperative and 30-day postoperative complications were also compared and were reviewed by organ system, these were categorized using the Clavien-Dindo Classification system. There was no significant difference in overall compliance in patients <65 compared to ≥65. Factors that increased compliance in patients ≥65 include laparotomy, hysterectomy, hyperlipidaemia, time after implementation of the protocol and primary surgeon. There was an increase in compliance from 19% to 77% over the 12-month study period. Intra and postoperative complications were similar between the two groups. Enhanced recovery in older patients undergoing pelvic reconstructive surgery is feasible with similar rates of compliance and complications compared to younger patients. Compliance with the protocol increases as time after implementation of the protocol increases in all patients.

Opioid Prescriptions for Female Pelvic Reconstructive Surgery Patients Before and After Implementation of Tennessee State Legislation.

OBJECTIVES: Limited data exist regarding the impact of state legislation on opioid-prescribing patterns, particularly in states with the highest opioid-prescribing rates in the nation. Our primary objective was to examine the change in the amount of opioid morphine equivalents (OMEs) prescribed at discharge to patients undergoing female pelvic reconstructive surgery after the implementation of state legislation created in response to the opioid crisis. METHODS: At our institution, state legislation went into effect on July 1, 2018, implementing limitations on OMEs prescribed to patients. This retrospective cohort study examines all adult women undergoing female pelvic reconstructive surgery from January 1, 2018, to December 31, 2018. The study compares prescribing practices 6 months before and 6 months after the state law was enacted. RESULTS: In total, 346 patients met inclusion criteria. The 2 groups had similar demographics. Surgical procedures were well distributed, with 52% of cases occurring in the first 6 months of the calendar year. At the time of discharge, 324 (96.7%) patients received an opioid prescription, with an overall average of 197 OMEs. After the implementation of state legislation on July 1, 2018, the amount of OMEs prescribed at discharge significantly decreased, from a median of 210 mg (interquartile range, 150-225) to 150 mg (interquartile range 135-225; P = 0.02). CONCLUSIONS: State legislation was associated with a significant decrease in prescribed OMEs at the time of discharge in patients undergoing female pelvic reconstructive surgery. These results support ongoing legislative efforts to address the current opioid crisis.

Influence of the urethral pressure transducer in measuring Valsalva leak point pressure in women undergoing multichannel urodynamic testing.

AIMS: To determine if the air-charged urethral sensor balloon currently used in urodynamic testing (UDS) significantly impacts Valsalva leak point pressure (VLPP) measurements. METHODS: This is a prospective cohort study of women undergoing UDS at an academic institution. VLPPs were obtained at 150 mL and urodynamic capacity with and without the urethral pressure sensor in the urethra. VLPP measurements were analyzed using a Wilcoxon signed-rank test. Median and interquartile range are presented. RESULTS: Sixty-three patients were enrolled in the study, 53 were included in the primary analysis. The mean age of the subjects was 56.2 ± 12.1 years. Nine patients (16%) solely leaked when the balloon was not present in the urethra either with cough or during VLPP measurement. At both 150 mL and urodynamic capacity, when VLPP testing was performed, there was a significant difference (cmH2 O) between the control and intervention values, (76.2 [55.0, 97.0] vs 68.8 [46.3, 93.3], P = .0012; 79.3 [53, 96.5] vs 72.5 [50.8, 92.3], P = .04). There was also a statistically significant difference between the control and intervention values for the lowest leak value at 150 mL and capacity (70.5 [51, 94.5] vs 60.0 [40, 88] P = .002; 73.5 [49.5, 91.5] vs 61 [45, 88], P = .017). CONCLUSIONS: The higher VLPPs obtained with the urethral balloon in place indicate that the balloon may be the cause of falsely elevated VLPPs during urodynamic testing. Additionally, the balloon may mask a diagnosis of stress urinary incontinence in some patients.

Symptomatic vulvar mucinous cyst: A case report and review of the literature.

BACKGROUND: Vulvar mucinous cysts are rare, benign, noninvasive masses. They can be mistaken for cysts of Bartholin gland, Skene gland, vestibular, or canal of Nuck. Generally, they may be left untreated, but observed. However, if symptomatic, they may require surgical removal. CASE: We report a large vulvar mucinous cyst in a 29-year-old woman with no contributory medical history. Excision of the mass was performed because its size had begun to cause symptoms. The diagnosis of a mucinous cyst was based on radiological and clinicopathologic features. The patient developed a post-operative vulvar hematoma and was discharged 2 days after the surgery with a Foley catheter in place. Continued follow-up was maintained for the hematoma, which drained spontaneously and resolved without incident. There has been no recurrence of the cyst after completion of short-term surgical follow-up. CONCLUSION: Vulvar mucinous cysts are rare masses. We present the diagnosis and treatment of a large vulvar mucinous cyst. The cyst was completely removed during surgery, but long-term surveillance for recurrence is currently being conducted.

The organic cation transporter-3 is a pivotal modulator of neurodegeneration in the nigrostriatal dopaminergic pathway.

Toxic organic cations can damage nigrostriatal dopaminergic pathways as seen in most parkinsonian syndromes and in some cases of illicit drug exposure. Here, we show that the organic cation transporter 3 (Oct3) is expressed in nondopaminergic cells adjacent to both the soma and terminals of midbrain dopaminergic neurons. We hypothesized that Oct3 contributes to the dopaminergic damage by bidirectionally regulating the local bioavailability of toxic species. Consistent with this view, Oct3 deletion and pharmacological inhibition hampers the release of the toxic organic cation 1-methyl-4-phenylpyridinium from astrocytes and protects against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced dopaminergic neurodegeneration in mice. Furthermore, Oct3 deletion impairs the removal of the excess extracellular dopamine induced by methamphetamine and enhances striatal dopaminergic terminal damage caused by this psychostimulant. These results may have far-reaching implications for our understanding of the mechanism of cell death in a wide range of neurodegenerative diseases and may open new avenues for neuroprotective intervention.
