RESUMO
BACKGROUND: Although multiple specialties perform neonatal circumcision (NC), overall NC proceduralist availability is limited. The approach to training new practitioners varies. This study aims to describe NC training experiences, current practices, and make suggestions for future improvements. METHODS: Perinatal physicians across 11 hospitals in a large Midwestern United States city who perform NC or who conduct newborn examinations and provide circumcision counseling were recruited for semistructured interviews about NC care. Interviews were transcribed; training-related comments underwent inductive and deductive qualitative coding. Themes related to circumcision training and recommendations for improving the experience of future circumcision learners were summarized. RESULTS: Twenty-three physicians (10 family medicine, 8 pediatrics, and 5 obstetrics; 78% currently perform circumcision) participated. All participants conducted newborn examinations and provided circumcision counseling, but only 21/23 were trained to perform circumcision. Several themes related to training emerged: (1) personal training experience, (2) training others to perform circumcision, and (3) current training needs and barriers. Most reported learning in residency by a "see one, do one, teach one" approach with minimal formal didactic or structured training. Compared with their personal experience, participants noted a shift toward more direct supervision and preprocedure preparation for current trainees. However, most reported that circumcision learning continues to be "hands-on." Participants desired a more structured approach for future trainees. CONCLUSIONS: Perinatal physicians noted a shift in the current NC training to a more hands-on approach than they experienced personally. Development of a structured NC curriculum was recommended to improve training.

OBJECTIVE: Over half of infant boys born in the United States undergo newborn circumcision. However, available data indicate that boys who are publicly insured, or Black/African American, have less access to desired newborn circumcision, thus concentrating riskier, more costly operative circumcision among these populations. This study ascertains perinatal physician perspectives about barriers and facilitators to providing newborn circumcisions, with a goal of informing future strategies to ensure more equitable access. METHODS: Qualitative interviews about newborn circumcision care were conducted from April-June 2020 at eleven Chicago-Area hospitals. Physicians that provide perinatal care (pediatricians, family medicine physicians, and obstetricians) participated in qualitative interviews about newborn circumcision. Inductive and deductive qualitative coding was performed to identify themes related to barriers and facilitators of newborn circumcision care. RESULTS: The 23 participating physicians (78% female, 74% white, median 16 years since medical school graduation [range 5-38 years], 52% hospital leadership role, 78% currently perform circumcisions) reported multiple barriers including difficulty with procedural logistics and inconsistent clinician availability and training; corresponding suggestions for operational improvements were also provided. Regarding newborn circumcision insurance coverage and reimbursement, physicians reported limited knowledge, but noted that some insurance reimbursement policies financially disincentivize clinicians and hospitals from offering inpatient newborn circumcision. CONCLUSIONS: Physicians identified logistical/operational, and reimbursement-related barriers to providing newborn circumcision for desirous families. Future studies and advocacy work should focus on developing clinical strategies and healthcare policies to ensure equitable access, and incentivize clinicians/hospitals to perform newborn circumcisions.

OBJECTIVE: To characterize changes in the proportion of newborn circumcisions performed by pediatric urologists and advanced practiced providers (APPs) in the United States over the last decade. METHODS: The Merative MarketScan Commercial Database was queried for newborn circumcision private health insurance claims (Common Procedural Terminology 54150) between 2010 and 2021. Setting (inpatient/outpatient), US Census Bureau region, clinician specialty, and patient age (days) were determined for the full study time period, and by study year. Simple linear regression assessed growth in proportion of newborn circumcisions performed by pediatric urologists and APPs (nurse practitioner/physician assistant/midwife), over time. RESULTS: In total, 1,006,748 newborn circumcisions (59% inpatient) were identified; while most were performed by obstetricians (45%) or pediatricians (33%); APPs performed 0.9%, and pediatric urologists performed 0.7%. From 2010-2021, the proportion of newborn circumcisions performed by pediatric urologists increased from 0.3% to 2.0% and by APPs in from 0.5% to 2.9% (P < .001 for both). Growth for both pediatric urologists and APPs occurred APPs predominantly from 2016 to 2021. Trends in proportion of newborn circumcision performed by pediatricians was stable [31.5% (2010) and 32.5% (2021)], but decreased for obstetricians [48.8% (2014) and 38.1% (2021)]. CONCLUSION: The proportion of newborn circumcisions performed by pediatric urologists and APPs increased more than 6-fold between 2010 and 2021, though both specialties still perform a minority of newborn circumcisions. These data provide important baseline information for newborn circumcision workforce planning, including evaluating collaborative care models where pediatric urologists train APPs to perform circumcision.

INTRODUCTION: Procedures involving the external genitalia are the most common pediatric urologic operations. Our group identified excess instrumentation for these cases to be a potential cause of operating room (OR) inefficiency at our large, freestanding pediatric hospital. This quality improvement (QI) initiative aimed to streamline surgical instrumentation for the most-performed pediatric urologic procedures at our hospital. MATERIAL AND METHODS: Six Sigma DMAIC methodology (Define, Measure, Analyze, Improve, Control) guided this multidisciplinary, iterative QI effort. A stakeholder team utilized data review, direct observations, and multiple in-person discussions to create a new "Groin-Penis Tray" (GPT) to replace a larger tray for the 90 most common pediatric urologic procedures. Suture preference cards and expectations about which sutures would be opened for each case were updated. The primary outcome was estimated yearly cost-avoidance due to reduced sterile processing. Additional outcomes included: instruments opened/case, % cases with complete trays, Mayo stand set-up time, and % cases with unused sutures. Balancing measures included: total median OR time and tray weights. Baseline and post-implementation measures were characterized and compared. RESULTS: A QI professional, 10 pediatric urologists, 2 pediatric urology fellows, and multiple OR and sterile processing staff members participated. The Summary Figure compares baseline and post-implementation measurements. The number of instruments opened/case decreased from 146 to 65. Annual sterile reprocessing costs decreased by >$51,000. Median Mayo stand set-up time decreased from 7.3 to 3.5 min (p < 0.001). The number of cases with complete trays increased from 7/20 (35%) to 11/20 (55%, p = 0.34). The new GPT is 2.7 kg lighter than the prior tray. Median OR time remained stable (baseline: 91 min; post-implementation: 102 min, p = 0.44). The number of cases with suture waste decreased from 78% to 0% immediately post-implementation but increased to 40% one year later. DISCUSSION: This systematic, iterative QI process spanned the course of â¼2 years, including planning, building, and updating new trays, then assessing longer-term success via the control phase. The new GPT is used for most pediatric urologic procedures at our hospital, and benefits include sterile reprocessing cost savings and ergonomics. Our team gained valuable experience related to assessing QI project scope, determining key stakeholders and roles, and strategies for sustainability that we will apply to future initiatives. CONCLUSIONS: Streamlining surgical trays for common pediatric urologic procedures at a large freestanding children's hospital using established QI methodology reduced OR cost by >$51,000/year and Mayo stand set-up times without compromising balancing measures.

Over half of boys in the United States undergo circumcision, which has its greatest health benefits and lowest risks when performed during the newborn period under local anesthesia. The COVID-19 pandemic has affected delivery of patient care in many ways and likely also influenced the provision of newborn circumcisions. Prior to the pandemic, we planned to conduct a qualitative study to ascertain physician perspectives on providing newborn circumcision care. The interviews incidentally coincided with the onset of the pandemic and thus, pandemic-related changes emerged as a theme. We elected to analyze this theme in greater detail. Semi-structured interviews were conducted with perinatal physicians in a large urban city from 4/2020 to 7/2020. Physicians that perform or counsel regarding newborn circumcision and physicians with knowledge of or responsibility for hospital policies were eligible. Interviews were transcribed verbatim and qualitative coding was performed. Twenty-three physicians from 11 local hospitals participated. Despite no specific COVID-19 related questions in the interview guide, nearly half of physicians identified that the pandemic affected delivery of newborn circumcision care with 8 pandemic-related sub-themes. The commonest sub-themes included COVID-19 related changes in: (1) workflow processes, (2) staffing and availability of circumcision proceduralists, and (3) procedural settings. In summary, this qualitative study revealed unanticipated COVID-19 pandemic-related changes with primarily adverse effects on the provision of desired newborn circumcisions. Some of these changes may become permanent resulting in broad implications for policy makers that will likely need to adapt and redesign the processes and systems for the delivery of newborn circumcision care.
RESUMO
INTRODUCTION: The Glans-Meatus-Shaft (GMS) Score is a pre-operative phenotypic scoring system used to assess hypospadias severity and risk for post-operative complications. The 'M' component is based on pre-operative meatal location, but meatal location sometimes changes after penile degloving, resulting in 'meatal mismatch.' OBJECTIVE: To identify: 1) the incidence and clinical predictors of meatal mismatch, and 2) the association of meatal mismatch with post-operative urethrocutaneous fistula development. STUDY DESIGN: We performed a retrospective cohort study on patients who underwent primary hypospadias repair at a single center from 2011 to 2018. Meatal mismatch was defined as: upstaging (meatus moving more proximally after degloving), downstaging (moving more distally after degloving), or none. Covariates included: pre-degloving meatal location, chordee severity, penoscrotal anatomy, pre-operative testosterone, and number of stages for repair. To test the association between meatal mismatch and fistula development, we constructed two, nested, multivariable Cox proportional hazards regression models with and without meatal mismatch and compared them with the likelihood ratio test. A sensitivity analysis excluded patients with <6 months of follow-up. RESULTS: Of 485 patients, 99 (20%) exhibited meatal mismatch, including 75 (15%) with upstaging and 24 (5%) patients with downstaging (Figure). Meatal mismatch was significantly associated with penoscrotal webbing, number of stages for repair, and pre-degloving meatal location, with downstaging being associated with more proximal meatal location. Over a median follow-up of 7.3 months (interquartile range 2.0-20.9), fistulae developed in 56 (12%) patients. On multivariable analysis, meatal upstaging was associated with a 3-fold increased risk of fistula development (Hazards Ratio [HR]: 3.04, 95% Confidence Interval [CI]: 1.44-6.45) compared to no mismatch. Meatal downstaging had similar risk of fistula development compared to no mismatch (HR: 0.99, 95% CI: 0.29-3.35). Multi-stage compared to single-stage repair was associated with reduced risk of fistula development (HR: 0.24, 95% CI: 0.09-0.66). The likelihood ratio test favored the model that included meatal mismatch. The sensitivity analysis showed similar findings. DISCUSSION: Our short-term results suggest that meatal mismatch may be an important additional consideration to the GMS score as a tool to assess hypospadias severity, counsel families, and predict outcomes. Longer-term studies are needed to enhance the precision of risk stratification in hypospadias. CONCLUSIONS: Meatal mismatch occurred in 20% of patients undergoing hypospadias repair. Among this cohort, meatal upstaging was associated with a 3-fold increased risk of post-operative urethrocutaneous fistula development.

Spina bifida (SB) patients afflicted with myelomeningocele typically possess a neurogenic urinary bladder and exhibit varying degrees of bladder dysfunction. Although surgical intervention in the form of enterocystoplasty is the current standard of care in which to remedy the neurogenic bladder, it is still a stop-gap measure and is associated with many complications due to the use of bowel as a source of replacement tissue. Contemporary bladder tissue engineering strategies lack the ability to reform bladder smooth muscle, vasculature, and promote peripheral nerve tissue growth when using autologous populations of cells. Within the context of this study, we demonstrate the role of two specific populations of bone marrow (BM) stem/progenitor cells used in combination with a synthetic elastomeric scaffold that provides a unique and alternative means to current bladder regeneration approaches. In vitro differentiation, gene expression, and proliferation are similar among donor mesenchymal stem cells (MSCs), whereas poly(1,8-octanediol-cocitrate) scaffolds seeded with SB BM MSCs perform analogously to control counterparts with regard to bladder smooth muscle wall formation in vivo. SB CD34(+) hematopoietic stem/progenitor cells cotransplanted with donor-matched MSCs cause a dramatic increase in tissue vascularization as well as an induction of peripheral nerve growth in grafted areas compared with samples not seeded with hematopoietic stem/progenitor cells. Finally, MSC/CD34(+) grafts provided the impetus for rapid urothelium regeneration. Data suggest that autologous BM stem/progenitor cells may be used as alternate, nonpathogenic cell sources for SB patient-specific bladder tissue regeneration in lieu of current enterocystoplasty procedures and have implications for other bladder regenerative therapies.

INTRODUCTION: Training in urology relies largely on the traditional methods of clinical immersion and the use of reference texts. Computer enhanced visual learning (CEVL) is an on-line learning tool that may effectively supplement these methods. We evaluate the role of CEVL in establishing the endoscopic diagnosis of posterior urethral valves (PUV). MATERIAL AND METHODS: This study compares test scores of PUV diagnosis made by pediatric urologists and fellows in pediatric urology training programs while watching pediatric cystourethroscopy videos before and after viewing the CEVL learning module. The CEVL module used illustrations and video clips to highlight criteria important in diagnosing PUV. Data was analyzed for improvement in test scores (Chi square). RESULTS: There were 112 study subjects enrolled. An improvement in the post-test scores was observed (p < 0.001). When independently analyzing cases with PUV, an improvement in diagnosis was also observed (p < 0.005). While a trend toward improvement was observed in correctly diagnosing normal urethras, this was not statistically significant. CONCLUSION: Overall, there was an improvement observed after viewing the CEVL module. This was most notable in cases where PUV was present. The CEVL module is an effective supplement for enhancing the endoscopic diagnosis of PUV.

BACKGROUND: The excision repair cross complementing (ERCC1) gene product plays a vital role in the nucleotide excision repair (NER) and DNA interstrand crosslink repair pathways, which protect the genome from mutations and chromosomal aberrations, respectively. Genetic deletion of Ercc1 in the mouse causes dramatically accelerated aging. We examined the effect of Ercc1 deletion in the development of prostate cancer in a prostate recapitulation model as Ercc1 deficient mice die within four weeks of birth. METHODS: Prostate tissues from Ercc1(-/-) mice or wild-type littermates were combined with embryonic rat urogenital mesenchyme and grown as renal grafts for a total of 8, 16, and 24 weeks before histological, expression and proliferative evaluation. RESULTS: Invasive adenocarcinoma was observed in Ercc1(-/-) tissue recombinants but not wild-type as early as 8 weeks post-grafting. PIN-like lesions in Ercc1(-/-) tissue recombinants had more cytologic and architectural atypia than wild-type (P = 0.02, P = 0.0065, and P = 0.0003 at the 8, 16, and 24 weeks, respectively), as well as more proliferative cells (P = 0.022 and P = 0.033 at 8 and 16 weeks, respectively). With serial grafting, Ercc1(-/-) tissue recombinants progressed to a more severe histopathological phenotype more rapidly than wild-type (P = 0.011). CONCLUSIONS: Results show that ERCC1 and by implication the NER and/or interstrand crosslink repair mechanisms protect against prostate carcinogenesis and mutations or polymorphisms affecting these DNA repair pathways may predispose prostate epithelial cells to transformation.

Animal models that have been used to examine the regenerative capacity of cell-seeded scaffolds in a urinary bladder augmentation model have ultimately translated poorly in the clinical setting. This may be due to a number of factors including cell types used for regeneration and anatomical/physiological differences between lower primate species and their human counterparts. We postulated that mesenchymal stem cells (MSCs) could provide a cell source for partial bladder regeneration in a newly described nonhuman primate bladder (baboon) augmentation model. Cell-sorted CD105(+) /CD73(+) /CD34(-) /CD45(-) baboon MSCs transduced with green fluorescent protein (GFP) were seeded onto small intestinal submucosa (SIS) scaffolds. Baboons underwent an approximate 40%-50% cystectomy followed by augmentation cystoplasty with the aforementioned scaffolds or controls and finally enveloped with omentum. Bladders from sham, unseeded SIS, and MSC/SIS scaffolds were subjected to trichrome, H&E, and immunofluorescent staining 10 weeks postaugmentation. Immunofluorescence staining for muscle markers combined with an anti-GFP antibody revealed that >90% of the cells were GFP(+) /muscle marker(+) and >70% were GFP(+) /Ki-67(+) demonstrating grafted cells were present and actively proliferating within the grafted region. Trichrome staining of MSC/SIS-augmented bladders exhibited typical bladder architecture and quantitative morphometry analyses revealed an approximate 32% and 52% muscle to collagen ratio in unseeded versus seeded animals, respectively. H&E staining revealed a lack of infiltration of inflammatory cells in grafted animals and in corresponding kidneys and ureters. Simple cystometry indicated recovery between 28% and 40% of native bladder capacity. Data demonstrate MSC/SIS composites support regeneration of bladder tissue and validate this new bladder augmentation model.

Urine leakage is an uncommon complication after renal cyst decortication that typically resolves with adequate drainage. With prolonged large volume urine leakage from a perinephric drain, however, consideration for open surgical repair must be taken into account. We present the successful management of persistent urine leakage after laparoscopic cyst decortication with endoscopic retrograde fibrin glue injection and ureteral stent placement.

Bladder regeneration studies have yielded inconclusive results possibly due to the use of unfavorable cells and primitive scaffold design. We hypothesized that human mesenchymal stem cells seeded onto poly(1,8-octanediol-co-citrate) elastomeric thin films would provide a suitable milieu for partial bladder regeneration. POCfs were created by reacting citric acid with 1,8-octanediol and seeded on opposing faces with human MSCs and urothelial cells; normal bladder smooth muscle cells and UCs, or unseeded POCfs. Partial cystectomized nude rats were augmented with the aforementioned POCfs, enveloped with omentum and sacrificed at 4 and 10 weeks. Isolated bladders were subjected to Trichrome and anti-human gamma-tubulin, calponin, caldesmon, smooth muscle gamma-actin, and elastin stainings. Mechanical testing of POCfs revealed a Young's modulus of 138 kPa with elongation 137% its initial length without permanent deformation demonstrating its high uniaxial elastic potential. Trichrome and immunofluorescent staining of MSC/UC POCf augmented bladders exhibited typical bladder architecture with muscle bundle formation and the expression and retention of bladder smooth muscle contractile proteins of human derivation. Quantitative morphometry of MSC/UC samples revealed muscle/collagen ratios approximately 1.75x greater than SMC/UC controls at 10 weeks. Data demonstrate MSC seeded POCfs support partial regeneration of bladder tissue in vivo.

Tissue engineering encompasses a multidisciplinary approach geared toward the development of biological substitutes designed to restore and maintain normal function in diseased or injured tissues. This article reviews the basic technology that is used to generate implantable tissue-engineered grafts in vitro that will exhibit characteristics in vivo consistent with the physiology and function of the equivalent healthy tissue. We also examine the current trends in tissue engineering designed to tailor scaffold construction, promote angiogenesis and identify an optimal seeded cell source. Finally, we describe several currently applied therapeutic modalities that use a tissue-engineered construct. While notable progress has clearly been demonstrated in this emerging field, these efforts have not yet translated into widespread clinical applicability. With continued development and innovation, there is optimism that the tremendous potential of this field will be realized.
RESUMO
We present the first report to our knowledge of progressive renal failure secondary to a retained intravesical foreign body. The urologic management of intravesical foreign bodies is challenging and is often complicated by a delay in presentation. Introduction into the bladder may be through a variety of means, including self insertion such as in this case. Extraction should be tailored according to the nature of the foreign body and should minimize bladder and urethral trauma. We report an unusual case of a 10 year delay in presentation after the insertion of two large intravesical foreign bodies manifesting as progressive renal failure and worsening lower urinary tract symptoms.

BACKGROUND: Photoselective laser vaporization of the prostate (PVP) is recognized as an alternative for the surgical management of BPH. Our experience suggests a higher incidence of persistent irritative symptoms than expected. Characteristics of our population were evaluated to determine whether postoperative symptomatology could be predicted. METHODS: We retrospectively reviewed those patients who underwent PVP at our institution between June 2004 and February 2006. Lower urinary tract symptoms as measured by the American Urological Association Symptom Index (AUA-SI) score and quality of life (QoL) score were recorded. In addition, peak urinary flow rate (Qmax) and ultrasound prostate volumes were also measured. PVP was performed using an 80 W KTP side-firing laser (LaserScope, San Jose, CA). Total energy used was recorded. AUA-SI score, QoL and Qmax were monitored at 1, 3 and 6 months postoperatively. RESULTS: Twenty-nine men were evaluated retrospectively. Their mean AUA-SI score, prostate volume and energy used were 17.8, 49.8 cm3 and 96.8 kJ respectively. At 1 month, 34 % complained of significant urgency, frequency and dysuria. Anticholinergic therapy was initiated in six patients. At 6 months, the number of patients complaining of symptoms decreased to 17% and five of the six patients were no longer requiring therapy. An association between finasteride therapy prior to PVP and post-operative symptoms was identified. In our series, 70% of those patients experiencing persistent symptoms had been managed with finasteride. No association between irritative voiding symptoms, laser energy utilized and volume of treated prostate gland was observed. However, a statistically significant association was noted between persistent irritative voiding symptoms and both lower preoperative AUA-SI scores and preoperative use of finasteride. CONCLUSIONS: Although a therapeutic benefit is observed following PVP, persistent irritative voiding symptoms are not uncommon. Lower preoperative AUA-SI scores and treatment with finasteride appear to be associated with bothersome postoperative symptoms. This information can be used to effectively select candidates and to counsel those patients with regard to both the therapeutic objective and expectations related to this procedure.

A traumatic rupture of the bladder in a healthy child is extremely rare and is usually not considered during evaluation of abdominal pain or sepsis. However, a delay in the diagnosis of bladder perforation can result in morbid and sometimes catastrophic outcomes. We report a delayed diagnosis of spontaneous rupture of a congenital bladder diverticulum in a previously healthy child. This case demonstrates that spontaneous bladder rupture may be a rare cause of abdominal complaints and sepsis when the etiology at first seems unclear.
