The conundrum of high-grade hydronephrosis with non-obstructive drainage on diuretic renography.

BACKGROUND: Patients with high grade hydronephrosis (HN) and non-obstructive drainage on mercaptoacetyltriglycine (MAG-3) diuretic renography (renal scans) can pose a dilemma for clinicians. Some patients may progress and require pyeloplasty; however, more clarity is needed on outcomes among these patients. OBJECTIVE: Our primary objective was to predict which patients with high-grade HN and non-obstructive renal scan, (defined as T ½ time <20 min) would experience resolution of HN. Our secondary objective was to determine predictors for surgical intervention. STUDY DESIGN: Patients with prenatally detected HN were prospectively enrolled from 7 centers from 2007 to 2022. Included patients had a renal scan with T ½<20 min and Society for Fetal Urology (SFU) grade 3 or 4 at last ultrasound (RBUS) prior to renal scan. Primary outcome was resolution of HN defined as SFU grade 1 and anterior posterior diameter of the renal pelvis (APD) < 10 mm on follow-up RBUS. Secondary outcome was pyeloplasty, comparing patients undergoing pyeloplasty with patients followed with serial imaging without resolution. Multivariable logistic regression was used for analysis. RESULTS: Of the total 2228 patients, 1311 had isolated HN, 338 patients had a renal scan and 129 met inclusion criteria. Median age at renal scan was 3.1 months, 77% were male and median follow-up was 35 months (IQR 20-49). We found that 22% (29/129) resolved, 42% of patients had pyeloplasty (54/129) and 36% had persistent HN that required follow-up (46/129). Univariate predictors of resolution were age≥3 months at time of renal scan (p = 0.05), T ½ time≤5 min (p = 0.09), SFU grade 3 (p = 0.0009), and APD<20 mm (p = 0.005). Upon multivariable analysis, SFU grade 3 (OR = 4.14, 95% CI: 1.30-13.4, p = 0.02) and APD<20 mm (OR = 6.62, 95% CI: 1.41-31.0, p = 0.02) were significant predictors of resolution. In the analysis of decision for pyeloplasty, SFU grade 4 (OR = 2.40, 95% CI: 1.01-5.71, p = 0.04) and T ½ time on subsequent renal scan of ≥20 min (OR = 5.14, 95% CI: 1.54-17.1, p = 0.008) were the significant predictors. CONCLUSIONS: Patients with high grade HN and reassuring renal scan can pose a significant challenge to clinical management. Our results help identify a specific candidate for observation with little risk for progression: the patient with SFU grade 3, APD under 20 mm, T ½ of 5 min or less who was 3 months or older at the time of renal scan. However, many patients may progress to surgery or do not fully resolve and require continued follow-up.

Undescended testis: A roundtable discussion based on clinical scenarios - Part 1.

Undescended testis (UDT, cryptorchidism) is the most common congenital anomaly of the genital tract. Despite its high incidence, the management of UDT varies between specialties (urology, pediatric surgery, pediatric urology, pediatric endocrinology). Therefore, as the European Association of Urology - Young Academic Urologists Pediatric Urology Working Group, we requested experts around the world to express their own personal approaches against various case scenarios of UDT in order to explore their individual reasoning. We intended to broaden the perspectives of our colleagues who deal with the treatment of this frequent genital malformation.

Intravenous acetaminophen for postoperative pain in the neonatal intensive care unit: A protocol for a pilot randomized controlled trial (IVA POP).

BACKGROUND: In neonates, uncontrolled pain and opioid exposure are both correlated with short- and long-term adverse events. Therefore, managing pain using opioid-sparing approaches is critical in neonatal populations. Multimodal pain control offers the opportunity to manage pain while reducing short- and long-term opioid-related adverse events. Intravenous (IV) acetaminophen may represent an appropriate adjunct to opioid-based postoperative pain control regimes. However, no trials assess this drug in patients less than 36 weeks post-conceptual age or weighing less than 1500 g. OBJECTIVE: The proposed study aims to determine the feasibility of conducting a randomized control trial to compare IV acetaminophen and fentanyl to a saline placebo and fentanyl for patients admitted to the neonatal intensive care unit (NICU) undergoing major abdominal or thoracic surgery. METHODS AND DESIGN: This protocol is for a single-centre, external pilot randomized controlled trial (RCT). Infants in the NICU who have undergone major thoracic or abdominal surgery will be enrolled. Sixty participants will undergo 1:1 randomization to receive intravenous acetaminophen and fentanyl or saline placebo and fentanyl. After surgery, IV acetaminophen or placebo will be given routinely for eight days (192 hours). Appropriate dosing will be determined based on the participant's gestational age. Patients will be followed for eight days after surgery and will undergo a chart review at 90 days. Primarily feasibility outcomes include recruitment rate, follow-up rate, compliance, and blinding index. Secondary clinical outcomes will be collected as well. CONCLUSION: This external pilot RCT will assess the feasibility of performing a multicenter RCT comparing IV acetaminophen and fentanyl to a saline placebo and fentanyl in NICU patients following major abdominal and thoracic surgery. The results will inform the design of a multicenter RCT, which will have the appropriate power to determine the efficacy of this treatment.

Non-refluxing Primary Megaureter in Children Resolves From Proximal to Distal.

OBJECTIVES: To evaluate a population of children with non-refluxing primary megaureter (NRPM), we investigated spontaneous resolution of ureteral dilation and the pattern (proximal to distal or distal to proximal) in which it occurs. METHODS: From our prospectively collected prenatal hydronephrosis (HN) database (0-24 months, 2008-2017), selecting those with NRPM (n = 92). We excluded patients who underwent surgery (n = 20), children with <6 months follow-up (n = 2) and without a voiding cystourethrogram (VCUG) (n = 4). Images were segregated into 198 ureteric segments (proximal/mid/distal). We defined resolution as Society for Fetal Urology (SFU) (0/1), anteroposterior diameter (APD) <10 mm, and ureteric dilatation <5 mm. Descriptive statistics and Kaplan-Meier curves were created for time-to-resolution analyses. RESULTS: Of 66 patients and 198 ureteral segments, median age at presentation was 2 months (0-12), 83% were male (33% circumcised). Mean APD at baseline was 11 ± 4 mm, and 79% had (SFU 3/4) HN. Mean dilatation of ureteral segments (mm) at baseline was: 9 ± 2 proximal, 9 ± 2 mid, and 11 ± 3 distal. At a median follow-up time of 26 (7-83) months, dilation of 55 (83%) proximal, 48 (72%) mid, and 22 (33%) distal ureteric segments had resolved. Overall, HN resolution occurred in 76% of patients. Resolution rates were similar for proximal/mid-ureters (83% vs 72%; P = .20); however, they were significantly different from distal segments (83% proximal vs 33% distal; 72% mid vs 33% distal, P <.01). CONCLUSION: Our data suggest that spontaneous resolution of NRPM follows a proximal to distal progression. Distal ureteric dilatation takes up to 10 months longer to resolve compared to that of proximal and mid-ureteric segments, as well as that of the renal pelvis.

Association of the Hydronephrosis Severity Score With Likelihood of Pyeloplasty: A Large Prospective Database Analysis.

OBJECTIVE: To apply and reproduce this scoring system in our prenatal hydronephrosis population with ureteropelvic junction obstruction (UPJO)-like hydronephrosis (HN), specifically looking at determining better HHS cutoffs that would allow for stratification into three risk categories: spontaneous HN resolution, observation, and surgery. METHODS: A prospectively collected prenatal hydronephrosis database was reviewed to extract UPJO-like HN patients. Children with vesicoureteral reflux, primary megaureter, bilateral HN, and other associated anomalies were excluded. Only patients who had an ultrasound and mercaptoacetyltriglycine renal scan at a minimum of 2-time points were included. Hydronephrosis Severity Score was calculated at the initial, interim, and last follow-up clinic visits. Scores were analyzed regarding its usefulness to determine which patients would have been more likely to undergo pyeloplasty. RESULTS: Of 167 patients, 131 (78%) were male, 119 (71%) had left UPJO-like, and 113 (67%) had a pyeloplasty. The median age at baseline was 2months (interquartile range 1-4). According to initial (first clinic visit) Hydronephrosis Severity Score, 5/36 (14%) patients with a 0-4 score, 93/116 (80%) with a 5-8 score, and 15/15 (100%) with a 9-12 score underwent pyeloplasty, respectively (P < .01). CONCLUSION: The proposed HHS system for UPJO-like HN patients is reproducible, however, cut-off values need to be reassessed to accurately reflect true risk categories, as the purpose of this system is to differentiate those who have HN severe enough to require intervention from those who can be managed nonsurgically. Changing risk groups to mild (0-3), moderate (4-6), and severe (7-12) allowed for better discrimination between patients who underwent surgical intervention from those who did not in our dataset.

Are weight or age limits for pediatric laparoscopic pyeloplasty? Results of a multicentric study.

INTRODUCTION: Anderson-Hynes pyeloplasty is the technique of choice for the treatment of pyeloureteral junction obstruction (PUJO) with an excellent success rate. Minimally invasive surgery has become the standard of care for the management of PUJO in children. Although it has been comparable to the open approach at all levels, its diffusion or employment in younger children has not been widely adopted. Our aim is to evaluate laparoscopic pyeloplasty outcomes from international academic centers in children under 1 year of age, focusing on feasibility and outcomes including possible complications. MATERIALS AND METHODS: This is review of consecutive infants under 1 year of age who underwent laparoscopic pyeloplasty between 2009 and 2018 with more than 12 months of follow-up. Seven different training centers with different backgrounds participated in this study. Evaluation was carried out with ultrasound and renogram before and after surgery. Demographic data, perioperative characteristics, complications, and results are described and analyzed. RESULTS: Over 9 years, 124 transperitoneal laparoscopic Anderson-Hynes pyeloplasties were performed on 123 children under 1 year of age; 88 males and 35 females, with 1 case of bilateral PUJO. Of the 124 renal units, 86 were left-sided. Mean age at surgery was 6.6 months (1 week-12 months), with 56% (n = 70) done before 6 months of age. Mean weight at surgery was 6.8 kg (3-12 kg), with 59% (n = 73) weighing less than 8 kg. Mean operative time (skin-to-skin) was 150 min (75-330 min). After a mean follow-up of 46 months (12-84 months), 12 (9%) patients developed complications, with only 1 needing a redo pyeloplasty also done laparoscopically. One child, with deterioration in renal function, underwent nephrectomy. CONCLUSION: Laparoscopic pyeloplasty under 1 year of age and/or less than 12 kilos is feasible with lower complication rate. Furthermore, age younger than 6 months and weight less than 8 kg are no longer limiting factors for a successful pyeloplasty as shown by this multicentre study.

Identifying variability in surgical practices and instrumentation for hypospadias repair across the Western Pediatric Urology Consortium (WPUC) network.

BACKGROUND: Although hypospadias outcomes studies typically report a level or type of repair performed, these studies often lack applicability to each surgical practice due to technical variability that is not fully delineated. An example is the tubularized incised plate (TIP) urethroplasty procedure, for which modifications have been associated with significantly decreased complication rates in single center series. However, many studies fail to report specificity in techniques utilized, thereby limiting comparison between series. OBJECTIVE: With the goal of developing a surgical atlas of hypospadias repair techniques, this study examined 1) current techniques used by surgeons in our network for recording operative notes and 2) operative technical details by surgeon for two common procedures, tubularized incised plate (TIP) distal and proximal hypospadias repairs across a multi-institutional surgical network. STUDY DESIGN: A two-part study was completed. First, a survey was distributed to the network to assess surgeon volume and methods of recording hypospadias repair operative notes. Subsequently, an operative template or a representative de-identified operative note describing a TIP and/or proximal repair with urethroplasty was obtained from participating surgeons. Each was analyzed by at least two individuals for natural language that signified specified portions of the procedure. Procedural details from each note were tabulated and confirmed with each surgeon, clarifying that the recorded findings reflected their current practice techniques and instrumentation. RESULTS: Twenty-five surgeons from 12 institutions completed the survey. The number of primary distal hypospadias repairs performed per surgeon in the past year ranged from 1-10 to >50, with 40% performing 1-20. Primary proximal hypospadias repairs performed in the past year ranged from 1-30, with 60% performing 1-10. 96% of surgeons maintain operative notes within an electronic health record. Of these, 66.7% edited a template as their primary method of note entry; 76.5% of these surgeons reported that the template captures their operative techniques very or moderately well. Operative notes or templates from 16 surgeons at 10 institutions were analyzed. In 7 proximal and 14 distal repairs, parameters for chordee correction, urethroplasty suture selection and technique, tissue utilized, and catheter selection varied widely across surgeons. CONCLUSION: Wide variability in technical surgical details of categorically similar hypospadias repairs was demonstrated across a large surgical network. Surgeon-specific modifications of commonly described procedures are common, and further evaluation of short- and long-term outcomes accounting for these technical variations is needed to determine their relative influence.

Buccal Mucosa Vaginoplasty Through an Anterior Sagittal Transrectal Approach (ASTRA) for Management of Yolk Sac Tumor in a 3-Year-Old Girl.

Vaginal yolk sac tumors are rare pediatric malignant tumors and the most common form of vaginal germ-cell tumors in children. They are almost exclusively found in females under 3 years of age. Treatment involves local excision either with or without chemotherapy. Herein, we describe a case of a 3-year-old girl with vaginal Yolk sac tumor, who underwent buccal mucosa vaginoplasty through an anterior sagittal transrectal approach , as an effective oncological procedure, with preservation of reproductive function.

Latitudes and attitudes: A multinational study of laparoscopic pyeloplasty in children.

PURPOSE: The Anderson-Hynes technique has been the treatment of choice for primary ureteropelvic junction obstruction in children. Laparoscopic approach has shown similar outcomes to open, with advantages of shorter hospital stay and less pain. We reviewed the experience of 11 geographically diverse, tertiary pediatric urology institutions focusing on the outcomes and complications of laparoscopic pyeloplasty. MATERIALS AND METHODS: A descriptive, retrospective study was conducted evaluating patients undergoing Anderson-Hynes dismembered laparoscopic pyeloplasty. Centers from four different continents participated. Demographic data, perioperative management, results, and complications are described. RESULTS: Over a 9-year period, 744 laparoscopic pyeloplasties were performed in 743 patients. Mean follow-up was 31 months (6-120m). Mean age at surgery was 82 months (1 w-19 y). Median operative time was 177 min. An internal stent was placed in 648 patients (87%). A catheter was placed for bladder drainage in 702 patients (94%). Conversion to open pyeloplasty was necessary in seven patients. Average length of hospital stay was 2.8 days. Mean time of analgesic requirement was 3.2 days. Complications, according to Clavien-Dindo classification, were observed in 56 patients (7.5%); 10 (1%) were Clavien-Dindo IIIb. Treatment failure occurred in 35 cases with 30 requiring redo pyeloplasty (4%) and 5 cases requiring nephrectomy (0.6%). CONCLUSION: We have described the laparoscopic pyeloplasty experience of institutions with diverse cultural and economic backgrounds. They had very similar outcomes, in agreement with previously published data. Based on these findings, we conclude that laparoscopic pyeloplasty is safe and successful in diverse geographics areas of the world.

A survey of parental perceptions and attitudes related to disclosure in hypospadias repair.

INTRODUCTION: Boys with hypospadias often undergo reconstructive surgery to improve cosmetic appearance and functional outcomes. While the ethics of physician-patient disclosure of illness are clear, parent-child disclosure is more ambiguous. There is a paucity of research regarding the parental disclosure of past urological procedures, specifically hypospadias repair. Our objective was to determine the rate of parental disclosure in boys undergoing hypospadias repair, and to evaluate the parental perspectives regarding concerns and amount of support in relation. METHODS: A web-based questionnaire was distributed to parents of 240 hypospadias patients at our pediatric urology outpatient clinic over 12 months. The questionnaire assessed intent to disclose, decisional regret, and cosmetic perception. Data was analyzed using descriptive statistics and chi-square analyses. RESULTS: Two hundred and twenty-three survey responses were collected. The majority of respondents were urban dwellers (72.2%), and the mothers of the child (80.9%). Distal hypospadias was the most common variant of condition (62.7%). When asked if they plan to disclose the repair to their child, 93% said "yes", and of those, the optimal mean age of disclosure was 7.49 ± 4.30 years. Ninety percent reported that they were not offered guidance on how/when to disclose, and 43% thought they would benefit from support on this. There was a significant difference in nervousness to disclose if the condition was distal versus proximal (χ2 = 15.19, p=<0.01), with proximal being more nervous. A significant difference was also observed regarding disclosure support with proximal being more likely to want formal support (χ2 = 4.55, p = 0.03). DISCUSSION AND CONCLUSIONS: As hypothesized, the majority of parents intended to disclose their son's surgery to them, but no statistically significant difference was seen between those with a distal vs. proximal repair. Additionally, demographic characteristics which were hypothesized to influence this decision (e.g., parents' level of education and relationship to the child) did not discriminate parental intent to disclose. To our knowledge, this is the first study to evaluate perceptions and attitudes around disclosure in patients with hypospadias and their families. The majority of respondents were planning to disclose the operation to their child, and were not offered any guidance or support as to the optimal way to disclose. Half of those parents thought they could benefit from resources to help them with this process. Further research is required to understand the impact of disclosure and to create tools to help caregivers with this responsibility.

Nephron-Sparing Approach For Familial Bilateral Synchronous Wilms Tumors.

Wilms tumors are the most common renal malignancy of childhood, often presenting as asymptomatic abdominal masses. These tumors can occur either in a unilateral or bilateral fashion, with bilateral tumors more commonly associated with various genetic syndromes and familial inheritance with some known loci. Bilateral tumors present challenges with regards to balancing oncologic control with renal function. Here, we present an unusual case of a young female patient diagnosed with bilateral Wilms tumors on the background of a strong family history and unknown genetic loci.

Risk of urinary tract infection in patients with hydroureter: An analysis from the Society of Fetal Urology Prenatal Hydronephrosis Registry.

BACKGROUND: Prenatal hydronephrosis is one of the most common anomalies detected on prenatal ultrasonography. Patients with prenatal hydronephrosis and ureteral dilation are at increased risk of urinary tract infection (UTI) and continuous antibiotic prophylaxis (CAP) is recommended. However, current guidelines do not define the minimum ureteral diameter that would be considered a dilated ureter in these patients. OBJECTIVE: We evaluate the definition of clinically relevant hydroureter, its association with UTI, and the impact of CAP. STUDY DESIGN: Patients with prenatal hydronephrosis from seven centers were enrolled into the Society for Fetal Urology Prenatal Hydronephrosis Registry from 2008 to 2020. Patients with ureteral measurement on ultrasound were included. Patients with ureterocele, ectopic ureter, neurogenic bladder, posterior urethral valves, horseshoe or solitary kidney, known ureteropelvic junction obstruction, or follow-up less than one month were excluded. Primary outcome was UTI. Analyses were performed using Cox regression. RESULTS: Of the 1406 patients enrolled in the registry, 237 were included. Seventy-six percent were male, ureteral diameter ranged from 1 to 34 mm, and median follow-up was 2.2 years. Patients with ureters 7 mm or greater had nearly three times the risk of UTI adjusting for sex, circumcision status, antibiotic prophylaxis and hydronephrosis grade (HR = 2.7, 95% CI: 1.1-6.5, p = 0.03; Figure). In patients who underwent voiding cystourethrogram (VCUG; 200/237), ureteral dilation of 7 mm or more identified patients at increased UTI risk controlling for sex, circumcision status, vesicoureteral reflux and hydronephrosis grade (HR = 2.3, 95% CI: 0.97-5.6, p = 0.06). CAP was significantly protective against UTI (HR = 0.50 (95% CI: 0.28-0.87), p = 0.01). Among patients who underwent VCUG and did not have vesicoureteral reflux, ureteral dilation 7 mm or greater corresponded with higher UTI risk compared to ureteral diameter less than 7 mm on multivariable analysis (HR = 4.6, 95% CI: 1.1-19.5, p = 0.04). CONCLUSIONS: This is the first prospectively collected, multicenter study to demonstrate that hydroureter 7 mm or greater identifies a high-risk group for UTI who benefit from antibiotic prophylaxis. In contrast, patients with prenatal hydronephrosis and non-refluxing hydroureter less than 7 mm may be managed more conservatively.

Evaluating the literature on preoperative androgen stimulation for hypospadias repair using the fragility index - can we trust observational studies?

BACKGROUND: Preoperative androgen stimulation (PAS) is typically used in hypospadias repair for patients with a proximal meatus or small glans size. Hypospadias PAS literature suffer from small sample sizes and lack of power to claim robust conclusions. Small changes in the number of events may completely change the statistical significance, making the conclusions drawn unreliable. Fragility index (FI) is the number of additional events needed to occur in either the control or experimental group to turn a statistically significant result to a non-significant result. The objective of the report was to assess the quality of available literature revolving around PAS use in hypospadias repair and its effects on post-operative complication rates using FI. METHODS: A comprehensive search of MEDLINE, EMBASE, and grey literature (ESPU and SPU abstracts) was conducted to identify RCTs and observational studies investigating the effect of PAS on complications post-hypospadias repair between 1990 and 2020. The FI was calculated for each study. Postoperative complications were defined as: fistula, stricture/stenosis, diverticula, and dehiscence. The odds ratio (OR), 95% confidence intervals (CI), corresponding p-values was calculated for each study. A random effects mixed model was implemented to combine the ORs for each study design. RESULTS: Fourteen studies qualified for inclusion, of which nine were observational studies and five were RCTs (Figure 1). The median sample size was 110 patients (IQR 69-171). The summary ORs for observational studies was 1.74 (95% CI: 1.10 to 2.74; p = 0.020) and for RCTs was 0.71 (9% CI: 0.34 to 1.47; p = 0.350). The median FI was 0 (IQR 0-2) of the included studies. DISCUSSION: PAS use does not appear to significantly affect complication rates shown in RCTs, however, observational studies cumulatively suggested significantly greater odds of complications after PAS. The FI is best used for RCTs with 1-to-1 randomization and binary data. Observational studies are rarely balanced for demographics and comorbidities with unequal sample size between comparable groups. The study was limited by substantial variability in how PAS was delivered to patients, leading to restricted comparability. CONCLUSION: Strong conclusions regarding the influence of PAS on hypospadias repair outcomes cannot be properly drawn based on the current literature due to deficits from either a statistical or methodological standpoint. The current PAS literature has shown inconclusive results, calling for well-designed RCTs, involving standardized surgical techniques and PAS protocols, to evaluate the true effect of PAS on complications post-hypospadias repair.

How I do it open distal ureteroureterostomy for ectopic ureters in infants with duplex systems and no vesicoureteral reflux under 6 months of age

ABSTRACT We describe a step by step technique for open distal ureteroureterostomy (UU) in infants less than 6 months presenting with duplex collecting system and upper pole ectopic ureter in the absence of vesicoureteral reflux (VUR).

Urethral plate quality assessment and its impact on hypospadias repair outcomes: A systematic review and quality assessment.

BACKGROUND: The variability of the urethral plate (UP) characteristics is one of the factors that influence technical choices for hypospadias correction. However, it is difficult to objectively evaluate the UP, leading to controversies in this subject, and vague terms utilized in the literature to describe its characteristics. OBJECTIVE: We aim to analyze the previously described methods used to characterize and evaluate UP quality, emphasizing the pros and cons of each system, and highlighting its possible influence on different postoperative outcomes. METHODS: We searched the databases PubMed, Embase, and Cochrane Library CENTRAL from January 1, 2000 to August 20, 2020. The following concepts were searched: urethra reconstruction/urethra replacement/urethroplasty AND hypospadias/hypospadias, AND children AND "plate" with the gray literature search. Subgroup analyses were also carried out. The quality of the involved studies was reviewed operating a modified version of the Newcastle-Ottawa Scale (NOS). RESULTS: 996 citations perceived as relevant to screening were retrieved. Thirteen studies were included comprising a total of 1552 cases. The number of patients in each study varied between 42 and 442, and the average post-surgical follow-up duration ranged between 6 months and twenty-six months. All studies used postoperative urethral stents of variable sizes and types. The impact of UP was most frequently assessed for cases treated with the tubularized incised plate (TIP) repair. CONCLUSION: The UP quality seems to play a role as an independent factor influencing postoperative outcomes of hypospadias repair. Currently used strategies for the appraisal of UP quality are highly subjective with a low index of generalizability. Various attempts to overcome these limitations exist but none was consistently accepted, leaving a wide space for creative investigation in order to obtain an objective, reproducible, precise, and well-validated tool.

What Do Patients and Parents Say About Parents' Ability to Choose Early Genital Surgery for Girls with Congenital Adrenal Hyperplasia?

PURPOSE: We assessed opinions of females with congenital adrenal hyperplasia and their parents about the parent's ability to choose early genital surgery for these patients. MATERIALS AND METHODS: We conducted an online survey of females with congenital adrenal hyperplasia (46XX,16+ years old) and independently recruited parents (2019-2020) diagnosed in first year of life in the United States. A multidisciplinary medical team, women with congenital adrenal hyperplasia and parents drafted the survey. Fisher exact test was used. RESULTS: Of 57 females with congenital adrenal hyperplasia (median age 39 years), 93.0% underwent genital surgery (median 1-2 years old). Most females (79.0%) believed legislation prohibiting surgery in childhood would cause harm. Most (64.9%) believed a ban "would have been harmful to me" (24.6% not harmful, 10.5% neutral). Most females (70.2%) believed a ban undermined parental rights to make medical decisions in their child's best interest. While 75.4% did not believe a ban was in the best interest of females with congenital adrenal hyperplasia, 14.0% did (10.5% neutral). For 132 parents of females with congenital adrenal hyperplasia (parent/child median age 40/11 years), 78.8% of children underwent surgery (median <1 year old). Most parents (93.9%) believed legislation prohibiting surgery in childhood would cause harm. Most (77.3%) believed a ban "would have harmed my daughter" (12.1% no harm, 5.3% neutral, 5.3% no answer). Parents were more likely than females with congenital adrenal hyperplasia to oppose a ban (p ≤0.02). Most parents (90.9%) believed a ban undermined parental rights. While 93.9% did not believe a ban was in the best interest of females with congenital adrenal hyperplasia, 3.8% did (2.3% neutral). CONCLUSIONS: The majority of females with congenital adrenal hyperplasia and their parents support the parents' ability to decide about potential genital surgery, opposing moratoria on surgery in childhood.

A guide to evaluating survey research methodology in pediatric urology.

Surveys are one of the most common study designs in healthcare research. They are easy to undertake, have minimal cost and aim to obtain reliable and unbiased information from a population of interest. Surveys in pediatric surgery/urology are an effective tool for gathering information on clinical practices for rare and complex conditions that highlight information on their behavior, institutional disparities, and healthcare paradigms. This education article consists of using a published survey by one of the authors as an example to demonstrate both positive and negative aspects, including limitations, of survey design studies with the purpose of helping pediatric urologists develop a framework to create and critically appraise survey methodology. Using this approach, readers should be able to reliably discern the methodological quality of published surveys.

Randomized Controlled Trial of Scrotal versus Inguinal Orchidopexy on Postoperative Pain.

INTRODUCTION: To compare the impact of orchidopexy approach (scrotal vs inguinal) on analgesic requirements, postoperative pain scores and complication rates. MATERIALS AND METHODS: A superiority randomized controlled trial including boys 10 to 95 months of age at surgery, diagnosed with palpable undescended testis, was conducted. Patients with nonpalpable or bilateral undescended testis, previous inguinal surgery on the ipsilateral side and concurrent procedures were excluded. Block randomization with 1:1 allocation ratio and a standardized anesthesia protocol were employed. The primary outcome was postoperative pain and analgesic use in-hospital and at home using the validated pain scales FLACC (Face, Legs, Activity, Cry, and Consolability Behavioural Scale), CHEOPS (Children's Hospital of Eastern Ontario Pain Scale), PPPM (Parents Postoperative Pain Measure) and TPPPS (Toddler-Preschooler Postoperative Pain Scale). Secondary outcomes included operative time, conversion and success rates, and complications. An intention to treat protocol was followed. RESULTS: We enrolled 173 patients, and 12 withdrew. Of the 161 patients who completed followup, 80 had scrotal orchidopexy and 81 inguinal orchidopexy. In-hospital use of ibuprofen (p=0.02) and acetaminophen (p <0.01), as well as FLACC (p <0.01) and CHEOPS (p=0.04) pain scores were slightly higher in patients who underwent orchidopexy. No difference in mean operative time and median at-home administration of analgesic was noted. The conversion rate was 24% (19/80). Of these, 13 (68%) were canalicular testes. The overall complication rate was 4% (6/161): 1 testicular atrophy, 3 re-ascents and 2 wound infections. Of these, 5 underwent scrotal orchidopexy and 1 had inguinal orchidopexy (wound infection). CONCLUSIONS: Even though in-hospital mean postoperative pain scores and analgesic consumption were slightly lower for scrotal orchidopexy cases, the pain levels were mild across all scales. Median at-home analgesic use and pain scores were similar for both groups, as well as operative time and complication rates. Scrotal orchidopexy is an effective alternative to inguinal orchidopexy for low-lying undescended testis, as 68% of cases that needed conversion were canalicular testes.

Medusa's Curls: Ureteropelvic Junction Obstruction Secondary to Multiple Long Intraluminal Polyps.

Fibroepithelial polyps represent a rare cause of intrinsic ureteropelvic junction obstruction in the pediatric population, accounting for less than 5% of cases. Herein, we present this peculiar case of a 10-year-old boy with multiple large intraluminal FEPs resembling Medusa's hair and the challenges associated with its subsequent treatment plan.
