The double-face onlay-tube-onlay transverse preputial flap: An advantageous alternative to the two-stage hypospadias repair?

OBJECTIVE: To compare the surgical outcomes and complications of boys who underwent double-face onlay-tube-onlay transverse preputial island flap (DFOTO) one-stage repair vs. two-stage repair for proximal hypospadias. STUDY DESIGN: Males with proximal hypospadias who underwent DFOTO or two-stage repair at a single institution from 2008 to 2021 were identified. Patients who had prior hypospadias surgery were excluded. Outcomes were surgical complications, number of surgical procedures, operative time, and post-operative uroflowmetry results. RESULTS: Fifty-three males who underwent DFOTO and 39 who underwent two-stage repair were included. Median age at surgery was 1.1 years (IQR 0.83-1.6) and median follow-up was 3.0 years (IQR 1.2-6.8). Although not statistically significant, the DFOTO group had higher rates of urethrocutaneous fistula (30% vs. 15%, p = 0.10), urethral stricture (15% vs. 3%, p = 0.07) and urethral diverticulum (8% vs. 3%, p = 0.39). Although the unplanned re-operation rate was higher in DFOTO (58% vs. 33%, p = 0.02), the mean number of procedures and median total surgical time were lower in DFOTO (1.8 ± 0.9 vs. 2.4 ± 0.8, p = 0.0004; 337 min [IQR 278-460] vs. 468 min [IQR 400-563], p = 0.008). There were no significant differences between groups for mean peak flow rates and post void residuals. CONCLUSIONS: In males who underwent DFOTO, 42% achieved completion of their proximal hypospadias repair with one operation, while the remainder had largely minor complications. Accounting for reoperation rates, the mean number of procedures per patient was lower in the DFOTO group. Comparable results can be achieved with both techniques; the risks of higher unplanned operation rates in the DFOTO group should be considered with the benefit of fewer total procedures.

Recurrent ventral curvature after corporoplasty with tunica vaginalis flap.

INTRODUCTION AND OBJECTIVE: Optimal means to correct ventral curvature (VC) is debated. Our preferred technique for curvature greater than 45° is corporoplasty using tunica vaginalis flap (TVF). We describe our complications with TVF for ventral lengthening. METHODS: Forty-four boys who underwent ventral lengthening with a corporoplasty with TVF were identified in a prospective database for proximal hypospadias repair by a single surgeon from 2008 to 2021. Corporotomy was performed by incising the tunica albuginea of the corpora cavernosa transversely at the point of maximum curvature. Harvested TVF was tailored to the size of the corporotomy and anastomosed to the edges of the tunica albuginea and on laid to the corporal defect with the mesothelial side of the TVF abutting the erectile tissue. RESULTS: Median age at surgery was 1.0 years (IQR 0.72-1.82). Median follow-up time was 4.9 years (IQR 2.6-8.0). Thirteen patients (27%) were older than 10 years of age at last follow up (median 13.3, range 10-20). Twenty-two boys (50%) received preoperative testosterone. The most common location of the meatus after degloving was penoscrotal (41%). Median VC after degloving was 90° (IQR 80-100). The urethral plate was transected in 43/44 (98%) of boys, improving median VC to 60° (IQR 40-60). After corporotomy, the median longitudinal distracted distance was 15 mm (IQR 12-17). Urethral reconstruction was most commonly achieved with the transverse island preputial flap technique or its modifications (39/44; 89%). Erections were reported in 42 boys (95%). None developed corporal diverticula, and two patients (4.5%) had ascended testis associated with TVF harvest. Seven percent of boys had recurrent ventral curvature (RVC; 3/44). Median RVC was 30° (IQR 30-45). One patient had RVC at the penoscrotal junction (not at site of prior corporoplasty) identified 11 years post operatively at age 15, and underwent dorsal plication. The other 2 patients were diagnosed less than 1 year post operatively. Both patients received testosterone due to small glans size, had double-face tubularized transverse island preputial flap as urethral and ventral skin coverage, and had endocrine and genetic consultation. Both had scarring of the preputial flap and of the corporoplasty. Scar excision and superficial transverse incisions on the tunica albuginea corrected RVC. CONCLUSIONS: The five-year outcome of ventral penile lengthening using TVF for corporoplasty is favorable with 7% of boys with RVC, and 4.5% with ascended testes associated with TVF harvest. None developed corporal diverticula.

Timely orchiopexy by 18 months of age: Are we meeting the standards defined by the 2014 AUA guidelines?

BACKGROUND: Cryptorchidism is one of the most common reasons for pediatric urology referral and one of the few pediatric urologic conditions in which there are established AUA guidelines that recommend orchiopexy be performed before 18 months of age. While access to timely orchiopexy has been studied previously, there is no current study with data from a national clinical database evaluating timely orchiopexy after the AUA guidelines were published. Additionally, prior studies on delayed orchiopexy may have included patients with an ascended testis, which is a distinct population from those with true undescended testicles. OBJECTIVES: To evaluate in a national, clinical database if timely orchiopexy improved after the AUA guidelines were published in 2014. In particular, we aim to evaluate a younger group of patients, 0-5 years of age, in an effort to account for potential ascending testes. STUDY DESIGN: Using Cerner Real-World Data™, a national, de-identified database of 153 million individuals, we analyzed pediatric patients undergoing orchiopexy in the United States from 2000 to 2021. We included males 0-18 years old and further focused on the subset 0-5 years. Primary outcome was timely orchiopexy, defined as age at orchiopexy less than 18 months. Predictor variables included race, ethnicity and insurance status. Statistical analyses were performed using logistic regression. RESULTS: Of the total 17,012 individuals identified as undergoing orchiopexy, 9274 were ages 0-5 at the time of surgery. Comparing time periods pre and post AUA guidelines (2000-2014 versus 2015-2021), we found a significant difference in the proportion of timely orchiopexy (51% versus 56%, respectively; p < 0.0001) (Figure). In multivariable analyses, Hispanic (OR = 0.65, p < 0.0001), African American (OR = 0.74, p < 0.0001), and Native American males (OR = 0.66, p = 0.008) were less likely to have timely orchiopexy compared to non-Hispanic White males. Individuals without insurance (OR = 0.81, p = 0.03) or with public insurance (OR = 0.88, p = 0.02) were less likely to have timely orchiopexy as compared to those with private insurance. CONCLUSIONS: Nearly a decade after publication of the AUA cryptorchidism guidelines, a large proportion of patients are still not undergoing orchiopexy by 18 months of age. This is the first study to show that timely orchiopexy has improved among patients 0-5 years, but the majority of patients are still not undergoing timely orchiopexy. Health disparities were apparent among Hispanic, African American, Native American, and uninsured males, highlighting the need for further progress in access to pediatric surgical care.

Home bladder pressure measurements correlate with urodynamic storage pressures and high-grade hydronephrosis in children with spina bifida.

BACKGROUND: Patients with spina bifida are at risk for developing bladder and renal deterioration secondary to increased bladder storage pressures. OBJECTIVES: To determine the association of home bladder volume and pressure measurements (home manometry) to: 1) detrusor storage pressures on urodynamics (UDS); and 2) the presence of Society of Fetal Urology (SFU) grades 3-4 hydronephrosis on renal bladder ultrasound in patients with spina bifida. METHODS: Data were prospectively collected on patients with spina bifida and neurogenic bladder requiring clean intermittent catheterization. Patients used a ruler and typical catheterization equipment to measure bladder pressures and volumes at home. Home measurements were compared to UDS detrusor pressures and SFU hydronephrosis grade. Detrusor pressure <20 cm H2O at 50% maximal cystometric capacity (MCC) on UDS was used as a measure of safe storage pressures on UDS; conversely, detrusor pressure >20 cm H2O was used a measure to capture both unsafe storage pressures and those with potential for unsafe storage pressures. Receiver-operator characteristic curves and area under curve (AUC) were calculated to depict the association between home manometry variables with detrusor pressures on UDS and SFU grades 3-4 hydronephrosis. RESULTS: Included were 52 patients with a median age of 10.3 years (interquartile range 6.3-14.4 years). Three home manometry measurements (maximum bladder pressure, bladder pressure at maximum catheterized volume, and mean bladder pressure) > 20 cm H2O were sensitive for Pdet >20 cm H2O at 50% MCC. Maximal bladder pressure >20 cm H2O was the most sensitive among home manometry measures (sensitivity 100%, specificity 70%, AUC 0.92 for Pdet >20 cm H2O at 50% MCC on UDS; sensitivity 100%, specificity 62%, AUC 0.89 for SFU grade 3-4 hydronephrosis). None of the patients who had maximum home bladder pressure <20 cm H2O had SFU grades 3-4 hydronephrosis; conversely, individuals with maximal home bladder pressure >20 cm had a wide range of hydronephrosis grades. CONCLUSION: None of the patients with maximal home bladder pressure <20 cm H2O had grade 3-4 hydronephrosis. Home measurements of maximal bladder pressure, bladder pressure at maximum catheterized volume and mean bladder pressure of >20 cm H2O were all sensitive for Pdet >20 cm H2O at 50% MCC on UDS. Home manometry is an inexpensive and simple technique to identify patients at risk for and to monitor individuals at high risk of upper tract dilation, without incurring significant cost or morbidity.

Single-Layer Acellular Porcine Bladder Matrix as Graft in Corporoplasty for Ventral Curvature in Pediatric Proximal Hypospadias Repair: An Initial Experience.

BACKGROUND: Single-layer ACell Cytal matrix (ACell Inc, Columbia, MD) is a commercially available, acellular scaffold derived from porcine bladder epithelial basement membrane and tunica propria. We describe our initial experience using Cytal as corporal graft in pediatric patients who underwent correction of ventral curvature in proximal hypospadias repair. METHODS: A retrospective review of a single-institution, 4 surgeon hypospadias database was performed between January 2020 and December 2021. Outcomes assessed were postoperative recurrent ventral curvature, corporal diverticulum, scarring on corporoplasty site on physical exam, and parental reports of atypical adverse effects. RESULTS: Ten males underwent correction of ventral curvature with Cytal as corporal graft for correction of ventral curvature were identified. All completed planned operations. Median age was 18.6 months (IQR 14.6-27.0). Median follow up was 14.1 months (IQR 8.9-16.5). Mean ventral curvature after degloving was 80 ± 50 degrees. All patients had straight erections. Nine of the 10 patients had straight erections verified at a subsequent artificial erection test at least 6 months from the corporoplasty (90%). The remaining patient underwent a double face onlay-tube-onlay transverse island preputial flap as a single-stage hypospadias repair and did not require any additional procedures. He had straight erections per parental history. None developed corporal diverticulum or demonstrated induration at site of corporoplasty on physical exam. There were no parental reports of atypical adverse systemic effects. CONCLUSION: In the short term, single-layer Cytal is effective as corporal graft for correction of ventral curvature in proximal hypospadias repairs without incurring additional donor site morbidity.

Taking "Trans-ano-rectal" out of ASTRA: An anterior sagittal approach without splitting the rectum.

The anterior sagittal trans-ano-rectal approach (ASTRA) provides excellent exposure to the urethra and vagina for partial or total urogenital sinus mobilization and subsequent reconstruction for patients with urogenital sinus anomalies. It is a frequent approach to reconstruction for children with a high confluence. However, the division of the anterior anal external sphincter and the rectal wall in the ASTRA incurs morbidity, which include fecal incontinence if one veers from the midline, and increased risk of wound infection due to fecal soilage. We demonstrate a modified technique to the ASTRA without dividing the anterior anal sphincter and rectal wall, with achievement of comparable exposure and excellent vaginal mobilization and length.

Is hyperbilirubinemia a contraindication for neonatal circumcision? A survey of practice patterns of pediatric urologists and a review of the literature.

INTRODUCTION AND OBJECTIVE: 50-80% of term newborns develop jaundice, or hyperbilirubinemia (HB), in their first week. The vast majority have benign etiologies, including physiologic jaundice of the newborn and breast milk/breastfeeding jaundice, which do not affect the synthetic capacity of the liver, thus conferring a low risk of peri-procedural bleeding. Though uncommon, HB in the setting of sepsis, biliary obstruction, or metabolic disease, may increase procedural bleeding risk. Circumcision of neonates with HB has not been well studied. We sought to characterize practice patterns among Society of Pediatric Urology (SPU) members and to explore whether HB confers increased bleeding risk for newborn circumcision. METHODS: An anonymous survey of 14 multiple-choice questions was sent to members of the SPU listserv. Questions regarding circumcision and HB were presented. We performed a literature review regarding whether HB confers increased surgical bleeding risk. RESULTS: 100/234 (43%) SPU members completed the survey. The majority (79/100) perform neonatal circumcision and use the Gomco© clamp (68%). 24/79 (30%) factor total bilirubin (Tbili) level in their decision prior to performing circumcision. Of those who consider HB a factor, 11/24 (46%) had cutoff Tbili levels at which they await improvement prior to proceeding. The most common cutoff level was Tbili level of 10-15 mg/dL (6/11, 55%). DISCUSSION: Existing data suggest a possible increased bleeding risk isolated to cases of HB in the setting of biliary obstruction or other associated relevant findings (ill infant, recent infection, congenital syndromes) or known personal/family history (fulminant liver disease, familial bleeding diatheses). While literature from Jewish Mohels and Talmudic discussion suggest that elevated Tbili may be a contraindication to circumcision, no scientific studies exist directly assessing the impact of HB on bleeding risk with circumcision. A review of the scientific literature suggests that isolated HB in otherwise healthy newborns does not increase bleeding risk. CONCLUSIONS: 30% of pediatric urologists survey respondents consider HB a potential contraindication to neonatal circumcision. Despite varied practices in circumcising jaundiced babies, neonatal jaundice rarely confers increased bleeding risks. While deferring circumcision is appropriate in an ill infant with HB, or in those with a genetic/congenital syndrome or with family history of coagulopathic, review of the scientific literature suggests that in otherwise healthy neonates, elevated Tbili likely represents benign causes and is unlikely to increase bleeding risk.

Advance Care Planning and Patient Preferences in a Feasibility Pilot Study to Improve End-of-Life Communication among Men with Metastatic Urological Malignancies.

INTRODUCTION: Rates of advance care planning for patients with cancer are poor despite efforts to enhance discussions regarding goals of care. Good patient-physician communication is critical to providing quality end-of-life care and, thus, it is important to identify effective interventions to improve systems through which patient preferences are addressed. METHODS: To improve rates of advance care planning as well as examine patient preferences regarding end-of-life care, we developed an integrated urology-palliative care clinic. All patients with a new diagnosis of a metastatic urological malignancy or castration resistant prostate cancer seen in a urology clinic within the Veterans Affairs Greater Los Angeles Healthcare System were offered a palliative care referral to be performed immediately after their urology appointment. The primary outcome was completion of an advance directive or POLST (Physician Orders for Life-Sustaining Treatment) form and the secondary outcome was patient preference regarding end-of-life care. RESULTS: A total of 59 patients were enrolled in the study between February 2012 and October 2016, and no patients were lost or excluded. There were 25 eligible patients who declined enrollment. Overall 85% of patients completed an advance directive or POLST form, and 98% chose to withhold cardiopulmonary resuscitation, advanced cardiac life support and artificially administered nutrition. CONCLUSIONS: High levels of advance care planning are achievable in an integrated urology-palliative care clinic and the majority of patients with a terminal illness are averse to aggressive end-of-life care.

Engaging patients in complex clinical decision-making: Successes, pitfalls, and future directions.

BACKGROUND: By 2022, there will be 18 million predicted cancer survivors, which is an estimated 30% more than the number of survivors in 2012. In prostate cancer alone, the most common cancer in American men other than skin cancer, 1 in 7 men will be diagnosed during their lifetime. Nevertheless, only approximately 1 in 39 will actually die of the disease. Although life expectancy is often good, these men have multiple treatment management options to choose from, including active surveillance, surgery, or radiotherapy, each of which carries its own array of long-term adverse effects. The same applies to renal cancer where patient have to sift through information to decide among active surveillance, partial nephrectomy, racial nephrectomy, robotic vs. open surgery, and ablation. BASIC PROCEDURES: Ultimately, patient, providers, and stakeholders lack high-quality evidence to effectively guide treatment decisions, and these decisions become even harder to discern when considering end-of-life care, palliative care, and the ethics regarding the new End of Life Option Act. As of November 1, 2016, the number of open urologic cancer clinical trials listed on ClinicalTrials.gov was 843. MAIN FINDINGS: Although we continue to make tremendous strides in urologic cancer care, our options for choosing the best treatment from a patient and provider standpoint are seemingly growing murkier. We need to continue to understand how health-related quality of life varies from patient to patient, and ultimately, incorporate patient preferences and values into the treatment decision in order to make high-quality treatment decisions. CONCLUSIONS: The remained of this articles will focus on the significant strides made in urologic oncology regarding these difficult decisions from localized disease to end-of-life care and also will detail what needs to be done as we continue to pivot forward.

Patient-reported outcome measures in urology.

PURPOSE OF REVIEW: Many urologic treatments have similar clinical outcomes, necessitating alternative methods to discriminate between options. Patient-reported outcome measures (PROMs) have become the new standard for evaluating the patient experience, and their use has drastically increased over the past decade. The purpose of this review is to discuss the status of PROMs in urology, highlight commonly used tools and address their future direction. RECENT FINDINGS: An increasing number of urology-specific PROMs tools have been developed and validated. An increased focus on patient-centered care has provided an impetus for their rise in use. Implementation of PROMs has transitioned from being primarily descriptive in nature to producing actionable findings. Many PROMs are now implemented in daily clinical practice. The future of PROMs will involve new instrument development, integration into clinical practice and the use of PROMs as performance measures. SUMMARY: PROMs are effective tools for characterizing symptom burden and health-related quality of life. With increasing clinical implementation, PROMs are playing an increasing role in patients' clinical decision-making.

Is More Really Better? An Examination of Services and Payment Patterns among Urologists from the Centers for Medicare & Medicaid Services.

INTRODUCTION: We examined provider and regional variation in services provided and payments made to urologists by CMS (Centers for Medicare & Medicaid Services) by linking payments to individual beneficiaries and examining the proportion of submitted charges resulting in payments. METHODS: We analyzed Medicare Part B Provider Utilization and Payment Data released by CMS for 2012, the last year of the purely fee-for-service reimbursement model. For each provider we determined the ratio of number of services provided to individual beneficiaries as well as the ratio of total submitted charges-to-total Medicare payments. Each provider was stratified into deciles of total Medicare payments and the mean per decile of total Medicare payment was calculated. Finally, to elucidate the potential association between the ratio of services-to-beneficiaries, we conducted multivariate linear regressions. RESULTS: The 20th, 40th, 60th and 80th percentiles for the ratio of number of services per individual beneficiary ratios to total Medicare Part B payments are 2.8, 4.0, 5.2 and 7.4, respectively. Urologists with greater payments received provided more services to individual beneficiaries. Submitted charges exceeded payments by 3:1. Finally, female providers had lower ratios (p <0.01) and there was significant regional variation in the ratio of services per unique beneficiary (p <0.001 for each of the 10 Standard Federal Regions). CONCLUSIONS: We found significant variation in services and payment in CMS. Reimbursement models replacing fee-for-service should be tailored to ensure appropriate health care resource utilization.
