RESUMO

PURPOSE: This manuscript summarizes the introduction, evolution and current outcomes for preference signaling in Urology as well as its use in other medical specialties. Overapplication plagues the residency recruitment process and PS has emerged as a process to improve the bottleneck of the interview selection process. RECENT FINDINGS: PS has been shown to be associated with a higher likelihood of interview among many subspecialties. Applicants and programs report satisfaction with the process. Further solutions are needed to increase transparency of program information and selection criteria to applicants so that critical decisions on which programs an applicant should apply to can be data driven.

RESUMO

INTRODUCTION/BACKGROUND: Enhanced Recovery After Surgery (ERAS) is a fundamental shift in perioperative care that has consistently demonstrated an improved outcome for a wide variety of surgeries in adults but has only limited evidence in the pediatric population. OBJECTIVE: We aimed to assess the success with and barriers to implementation of ERAS in a prospective, multi-center study on patients undergoing complex lower urinary tract reconstruction. STUDY DESIGN: Centers were directed to implement an ERAS protocol using a multidisciplinary team and quality improvement methodologies. Providers completed pre- and post-pilot surveys. An audit committee met after enrolling the first 5 patients at each center. Pilot-phase outcomes included enrollment of ≥2 patients in the first 6 months of enrollment, completion of 90 days of follow-up, identification of barriers to implementation, and protocol adherence. RESULTS: A total of 40 patients were enrolled across 8 centers. The median age at surgery was 10.3 years (IQR 6.4-12.5). Sixty five percent had a diagnosis of myelomeningocele, and 33 % had a ventriculoperitoneal shunt. A bladder augmentation was performed in 70 %, Mitrofanoff appendicovesicostomy in 52 %, Monti ileovesicostomy in 15 %, and antegrade continence enema channel in 38 %. The most commonly perceived barriers to implementation on the pre-pilot survey were "difficulty initiating and maintaining compliance with care pathway" in 51 % followed by a "lack of time, money, or clinical resources" in 36 %. The pre-pilot study experience, implementation, and pilot-phase outcomes are provided in the Table. All primary and secondary outcomes were achieved. DISCUSSION: The findings of the present study were similar to several small comparative studies with regard to the importance of a multidisciplinary team, strong leadership, and continuous audit for successful implementation of ERAS. Similar barriers were also encountered to other studies, which primarily related to a lack of administrative support, leadership, and buy-in from other services. The limitations of the present study included a relatively small heterogeneous cohort and absence of a comparative group, which will be addressed in the larger exploratory phase of the trial. The findings may also not be generaziable due to the need for sustainable processes that were unique to each center as well as an absence of adequate volume or resources at smaller centers. CONCLUSIONS: ERAS was successfully implemented for complex lower urinary tract reconstruction across 8 centers through a multidisciplinary team, structured approach based on the local context, and focus on a continuous audit.

RESUMO

INTRODUCTION: In 2014, the AUA published guidelines regarding the evaluation of cryptorchidism. This multi-institutional study aims to determine if these guidelines reduced the age of referral and the utilization of ultrasound in boys with cryptorchidism. We hypothesize that delayed referral continues, and utilization of ultrasound remains unchanged. METHODS: A retrospective review of boys referred for the evaluation of cryptorchidism was performed at 4 academic institutions, collecting data for 1 year prior (2013) and 2 nonconsecutive years following guideline creation (2015 and 2019). Across these time frames, we compared median ages at evaluation and surgery, and rates of patient comorbidities, orchiopexy, and preevaluation ultrasound. RESULTS: A total of 3,293 patients were included. The median age at initial pediatric urology evaluation in all cohorts was 39 months (IQR: 14-92 months). Following publication of the AUA Guidelines, there was no difference (P = .08) in the median age at first evaluation by a pediatric urologist between 2013 and 2015, and an increase (P = .03) between 2013 and 2019. Overall, 21.2% of patients received an ultrasound evaluation prior to referral, with no significant difference between 2013 and 2015 (P = .9) or 2019 (P = .5) cohorts. CONCLUSIONS: Our data suggest that, despite publication of the AUA Guidelines on evaluation and treatment of cryptorchidism, there has been no reduction in the age of urological evaluation or the utilization of imaging in boys with undescended testis. Finding alternative avenues to disseminate these evidence-based recommendations to referring providers and exploring barriers to guideline adherence is necessary to improve care for patients with cryptorchidism.

RESUMO

OBJECTIVE: To assess the perceptions and outcomes of the A preference signaling (PS) pilot implemented by the Society of Academic Urology in the 2021-2022 Urology Match cycle. METHODS: Five non-weighted signals were provided to each applicant, and signals were delivered to programs by the American Urological Association to provide an applicant-centered formal and equitable process to express genuine interest in residency programs. Applicant and program perception and behavior was assessed through surveys. Signal distribution, mean, range, and interview offer rates for overall, signaled, and non-signaled programs were calculated. RESULTS: In the 2021-2022 Urology Match cycle, 566 applicants completed signaling; 2829 total signals were sent to programs with 97% applicant and 100% program participation. Each program received a mean number of 19 signals (range of 1-62), and 25% of programs received 49% of all signals. The overall interview-offer rate for the cohort was 12.5% (6019 interviews held/47,989 applications received); the signaled interview rate was 51% (1443/2829), and the non-signaled interview rate was 10% (4576/45,160) with an approximate 4-fold increase in rate of interview for signaled programs compared to non-signaled programs. There was moderate to high levels of satisfaction from applicants and programs on the overall process. 48% of programs incorporated PS into initial application review. CONCLUSION: Preference signaling was demonstrated to be feasible and successful in providing a novel applicant-directed, formal, equitable, and credible structured process for applicants to express genuine interest in programs. Additionally, programs were able to incorporate PS into their interview selection and recruitment process.

RESUMO

Clear cell sarcoma of the kidney (CCSK) is the second most common pediatric renal malignancy after Wilms tumor. CCSK has the potential to metastasize to distant sites and was historically known as the bone metastasizing renal tumor. We report an exceedingly rare case of a bladder recurrence of CCSK. Our patient presented with gross hematuria 7 years after initial complete response. He was found to have a large sessile bladder tumor and underwent a partial cystectomy with right pelvic lymph node dissection. Final pathology was metastatic CCSK.

RESUMO

PURPOSE: We evaluated our long-term experience with intrasphincteric botulinum toxin A injection in children with dysfunctional voiding. MATERIALS AND METHODS: From January 2006 through July 2012 we saw 2,172 neurologically normal children due to dysfunctional voiding. Of patients who presented to these visits we retrospectively identified the charts of 12 with dysfunctional voiding (8 females) in whom urotherapy and medical management failed and who underwent botulinum toxin A injection to the external urinary sphincter. Mean patient age at surgery was 10.5 years (range 4 to 19). Average followup was 45 months (range 20 to 71). Preoperatively and postoperatively all children were evaluated with history and physical examination, voiding diary, renal and pelvic ultrasound with post-void residual volume measurement and uroflowmetry. RESULTS: Eight of the 12 children (67%) experienced significant improvement in voiding parameters. Before vs after treatment mean ± SD post-void residual urine volume was 115 ± 83 vs 57 ± 61 ml (p = 0.016) and the mean maximum flow rate was 11.8 ± 8.1 vs 20.4 ± 7.9 ml per second. Half of the cohort required a second injection an average of 15 months later. Three of the 4 patients who failed to show improvement had neuropsychiatric problems and 1 had evidence of bladder underactivity. CONCLUSIONS: Our results demonstrate reasonable efficacy and durability of intrasphincteric botulinum toxin A injection in children with refractory dysfunctional voiding. Neuropsychiatric issues appear to negatively influence the success rate. Long-term followup is vital to identify patients in whom repeat injection may be necessary.

RESUMO

PURPOSE: There is emerging awareness of comorbid psychosocial characteristics in children with lower urinary tract dysfunction. To explore the prevalence of these comorbidities and their relationship to lower urinary tract symptoms, we examined the psychosocial comorbidities and body mass index of children with lower urinary tract dysfunction. MATERIALS AND METHODS: We prospectively collected data on all new patients 6 to 17 years old with nonneurogenic lower urinary tract dysfunction who presented to a single nurse practitioner in 2011. Parents completed a 21-question lower urinary tract symptom score based on a validated questionnaire and a psychosocial questionnaire that screened for stressful life events and psychological diagnoses. We examined the correlation of body mass index percentile and psychosocial comorbidities with lower urinary tract symptom score. RESULTS: Of the 358 patients 28.5% were obese, 31.8% had a recent life stressor and 22.9% had a comorbid psychiatric disorder. Younger age correlated with a higher lower urinary tract symptom score (r = -0.34, p <0.0001). Children with a recent life stressor (p = 0.049), psychiatric disorder (p = 0.0026) or the 2 comorbidities (p = 0.039) had a significantly higher lower urinary tract symptom score than children without comorbidities. Underweight and obese children had a significantly higher lower urinary tract symptom score than healthy weight and overweight children (p = 0.009). CONCLUSIONS: Almost a third of the patients in our study were obese. More than 40% of the children had a psychiatric disorder and/or recent life stressor. Younger age, an underweight or obese body mass index and a recent stressful life event or psychiatric disorder correlated with a higher lower urinary tract symptom score. This study supports previous recommendations to screen for psychosocial comorbidities and obesity during the evaluation of pediatric lower urinary tract dysfunction.

RESUMO

PURPOSE: We elucidate the role of endopyelotomy as a primary and secondary intervention for ureteropelvic junction obstruction in children. MATERIALS AND METHODS: We retrospectively identified 79 pediatric patients who underwent endopyelotomy for ureteropelvic junction obstruction between 1986 and 2011. Eleven patients were lost to followup and were excluded from analysis. Patient demographics, operative information, complications and success rates were reviewed for the remaining 68 patients. Treatment success was defined as the absence of symptom recurrence and improved radiographic features on ultrasound, computerized tomography, diuretic renogram or excretory urogram at most recent followup. RESULTS: Primary endopyelotomy data were analyzed in 37 patients with a median age of 11.1 years. The success rate was 65% at a median followup of 34 months (range 1.5 to 242). Treatment failure occurred in 13 patients with a median time to failure of 8 months (range 1.5 to 131). There were 8 cases of failure during 12 months of surgery. Secondary endopyelotomy data were analyzed in 31 patients with a median age of 6.5 years. The success rate was 94% at a median followup of 61 months (range 1 to 204). Treatment failure occurred in 2 patients at 1 and 6 months. Approximately two-thirds of all procedures used an antegrade approach. CONCLUSIONS: Primary endopyelotomy is significantly less successful than pyeloplasty in the treatment of ureteropelvic junction obstruction in pediatric patients. However, secondary endopyelotomy following failed pyeloplasty represents a viable alternative to redo pyeloplasty.

RESUMO

PURPOSE: Children with end-stage renal disease and bladder dysfunction may require augmentation cystoplasty before kidney transplantation. Previous reports have suggested unacceptable urinary tract infection rates in these immunosuppressed patients. We reviewed our experience in this population. MATERIALS AND METHODS: We retrospectively studied patients undergoing augmentation cystoplasty and subsequent renal transplantation by a single surgeon between 1989 and 2007. This cohort was compared with a control group on clean intermittent catheterization who had undergone transplantation without augmentation. Patient demographics, etiology of renal failure, surgical details, surgical/allograft outcomes and occurrence of urinary tract infection were analyzed. RESULTS: The augmented group included 17 patients with a median age at reconstruction of 6.4 years. Stomach was used in 15 patients and colon in 2. Median time between reconstruction and transplantation was 1.2 years. Median followup after transplantation was 7.7 years. The control group included 17 patients with a median age at transplantation of 10.9 years. Median followup in the controls was 6.1 years. All ureteral reimplantations were antirefluxing. Patients on clean intermittent catheterization were maintained on oral antibiotic suppression and/or gentamicin bladder irrigations. In the augmented group 35 episodes of urinary tract infection were noted, and the number of documented infections per patient-year of followup was 0.22, compared to 32 episodes of urinary tract infection and 0.28 infections per patient-year of followup in the controls. No allograft was lost to infectious complications. CONCLUSIONS: In our series there was no increase in urinary tract infection rate following renal transplantation in patients with augmented bladders compared to controls. This finding may be due to the use of gastric augmentation, antirefluxing reimplantation and gentamicin irrigations.

RESUMO

PURPOSE: Voiding cystourethrogram is an invasive test that evokes anxiety. Our primary aim was to determine whether midazolam is beneficial in decreasing anxiety in children who undergo voiding cystourethrogram. Secondary aims were an examination of parent anxiety, health care professional perceptions and post-procedure behavioral outcomes in children after voiding cystourethrogram. MATERIALS AND METHODS: A total of 44 children were randomized to placebo or oral midazolam before voiding cystourethrogram in double-blind fashion. The Modified Yale Preoperative Anxiety Scale was used to evaluate child behavior before and during voiding cystourethrogram, and the Post Hospitalization Behavior Questionnaire was used to investigate any short-term and intermediate-term behavioral outcomes. The State-Trait Anxiety Inventory was used to evaluate parent personal anxiety during voiding cystourethrogram. A separate questionnaire was administered to radiology staff. Statistical analysis included the 2-sample t and Fisher exact tests. RESULTS: There was no difference in Modified Yale Preoperative Anxiety Scale scores in children randomized to midazolam or placebo. There was also no significant difference in parent anxiety. Radiology care providers identified no reliable benefit when blinded to sedation vs placebo. We did not note any post-procedural behavior issues after voiding cystourethrogram at up to 6 months of followup. CONCLUSIONS: Midazolam may not significantly help with child or parent anxiety during voiding cystourethrogram. No reliable benefit was noted according to radiology health care provider perception and there was no significant post-procedural behavior benefit. Midazolam may not provide a significant benefit in decreasing anxiety during voiding cystourethrogram.

RESUMO

PURPOSE: Endoscopic injection of dextranomer/hyaluronic acid is an option for primary vesicoureteral reflux. Few groups have assessed the rate of urinary tract infection after dextranomer/hyaluronic acid injection. We reviewed our experience with dextranomer/hyaluronic acid injection, and determined the incidence of and risk factors for postoperative urinary tract infection. MATERIALS AND METHODS: A retrospective cohort study was performed of all children with primary vesicoureteral reflux treated with dextranomer/hyaluronic acid from 2002 to 2007 at a single institution. Patient demographics and clinical outcomes were abstracted from the medical record. Risk factors for postoperative urinary tract infection, including female gender, preoperative vesicoureteral reflux grade, recurrent urinary tract infection, bladder dysfunction, nephropathy and persistent vesicoureteral reflux after surgery, were analyzed in a multivariate logistic regression model. RESULTS: We treated 311 children, of whom 87% were female and 13% were male (464 renal units), during the study period. Mode of presentation was urinary tract infection in 85% of cases. Mean followup was 2.6 years. Postoperatively urinary tract infection developed in 40 patients (13%) and febrile urinary tract infection developed in 11 (3.5%). Of patients with urinary tract infection 26 had initially negative postoperative voiding cystourethrogram, of whom 16 underwent repeat voiding cystourethrogram and 9 showed recurrent vesicoureteral reflux. Five of these 9 patients had clinical pyelonephritis. Of assessed risk factors only preoperative recurrent urinary tract infection (OR 2.2, p = 0.03) and bladder dysfunction (OR 3.3, p = 0.001) were independent predictors of post-injection urinary tract infection. CONCLUSIONS: In our series urinary tract infection after dextranomer/hyaluronic acid injection was rare. Patients with recurrent urinary tract infections and bladder dysfunction preoperatively are at increased risk for urinary tract infection after treatment. Patients with febrile urinary tract infection after dextranomer/hyaluronic acid injection are at high risk for recurrent vesicoureteral reflux.

RESUMO

The study reported here was undertaken to investigate a novel method of systematic, 3-dimensional, template-guided, transrectal ultrasound-guided prostate biopsy. The TargetScan transrectal ultrasound and prostatic biopsy system (Envisioneering Medical Technologies, St. Louis, MO) uses a stationary transrectal ultrasound probe that acquires 3-dimensional and simultaneous biplanar ultrasound imaging. With the use of prostate-specific measurements, targeted transrectal biopsy specimens of the prostate are taken. The precise location of each specimen is defined by 2 coordinates: depth in centimeters proximal from the apex of the prostate, and degree of rotation (clockwise or counterclockwise from 12 o'clock). This device has been evaluated when used with radical prostatectomy specimens. Studies on 20 radical prostatectomy specimens disclosed that simulated TargetScan biopsy correctly identified cancer in 16 (80%) prostates and high-grade prostatic intraepithelial neoplasia in 2 others. Simulated TargetScan biopsy correctly characterized 88% of prostatic octants in terms of whether or not they harbored cancer. This technique was reproducible from operator to operator, and 85% biopsy core concordance was attained when the TargetScan protocol was simulated in 2 urology residents. The TargetScan biopsy system seems to be an effective transrectal alternative to transperineal, 3-dimensional, ultrasound-guided biopsies. Its reproducibility from operator to operator suggests that it may be useful for guiding rebiopsy of specific locations within the prostate and for providing targeted focal prostate cancer therapy.

RESUMO

PURPOSE: We have shown that preoperative plasma levels of transforming growth factor-beta(1) (TGF-beta(1)), interleukin 6 (IL)-6, and its receptor (IL-6sR) are associated with prostate cancer progression and metastasis. The objectives of this study were to confirm these findings and to examine the association of changes in plasma levels of these markers after surgery with disease progression in a large consecutive cohort of patients. EXPERIMENTAL DESIGN: Plasma levels of TGF-beta(1), IL-6, and IL-6sR were measured pre- and postoperatively (6-8 weeks after surgery) in 302 consecutive patients who underwent radical prostatectomy for clinically localized disease. RESULTS: Pre- and postoperative levels of TGF-beta(1) were significantly elevated in patients with extraprostatic extension, seminal vesicle involvement, and metastases to lymph nodes. In contrast, preoperative levels of IL-6 and IL-6sR, but not postoperative levels, were significantly associated with tumor volume, prostatectomy Gleason sum, and metastases to lymph nodes. In a postoperative model that included pre- and postoperative TGF-beta(1), IL-6, and IL-6sR and standard postoperative parameters, postoperative TGF-beta(1) and prostatectomy Gleason sum were significant predictors of overall and aggressive disease progression. Although, for all patients, plasma levels of all three markers declined significantly after prostate removal, for patients that experienced disease progression, only IL-6 and IL-6sR levels decreased significantly. CONCLUSIONS: For patients undergoing radical prostatectomy, preoperative plasma levels of TGF-beta(1) and IL-6sR are associated with metastases to regional lymph nodes, presumed occult metastases at the time of primary treatment, and disease progression. After prostate removal, postoperative TGF-beta(1) level increases in value over preoperative levels for the prediction of disease progression.
