Isolated posterior urethral valves (PUV) and anterior urethral valves (AUV) with and without concomitant PUV: Matched cohort study at a high-risk pediatric center.

OBJECTIVES: To compare postnatal outcomes of AUV and PUV patients to evaluate for potential differences between these conditions, given that anterior urethral valves (AUV) with or without concomitant posterior urethral valves (PUV) is a rare congenital anomaly leading to lower urinary tract obstruction (LUTO). METHODS: We reviewed our LUTO database and included patients with AUV or concomitant AUV+PUV, managed at our institution between 2003 and 2023 matching them to comparable PUV cases. Assessed variables included prenatal diagnosis, gestational age (GA) at birth, initial management, kidney function, presence and degree of hydronephrosis (HN), and need for renal replacement therapy (RRT). RESULTS: The AUV ± PUV group (AUV: n=11, concomitant PUV: n=2) and PUV group (n=26) had similar presenting ages and follow-up times (p>0.05). Only 15.4% of AUV cases presented prenatally compared to 72.0% of PUV cases (p=0.0016), leading to delayed postnatal management in AUV patients (p=0.0260). Findings at presentation included UTI, weak stream or a palpable penile mass. PUV patients demonstrated significantly higher creatinine levels at the initial visit and at last follow-up (p=0.0120 and p=0.0302) than the AUV ± PUV group, with only one patient requiring RRT (p>0.05). At the last follow-up, no patient in the AUV ± PUV group required clean intermittent catheterization compared to 37.5% in the PUV group (p=0.0331) which also demonstrated more patients with persistent HN (p=0.0039). CONCLUSION: AUV with or without concomitant PUV is a rare finding that should be considered in patients presenting with weak stream, UTI, and penile swelling. Our data suggests potential differences in presentation and less severe postnatal outcomes in AUV compared to PUV patients.

Expert classification of hypospadias: an external validation and evaluation of agreement for Glans-Urethral Meatus-Shaft (GMS) and Hypospadias Objective Penile Evaluation (HOPE) scores.

PURPOSE: This study evaluates the inter-rater agreements of both the Glans-Urethral Meatus-Shaft (GMS) hypospadias score and Hypospadias Objective Penile Evaluation (HOPE) score, aiming to standardize disease classification for consistent agreement in clinically relevant characteristics of hypospadias. METHODS: Photos of hypospadias in children were collected from two separate institutions. Three raters scored the photos using GMS and HOPE, excluding penile torsion and curvature assessment in HOPE due to photo limitations. RESULTS: A total of 528 photos were included. With GMS, Fleiss' multi-rater kappa showed an agreement of 0.745 for glans-urethral plate, 0.869 for meatus, and 0.745 for shaft. For HOPE scores, the agreements were 0.888 for position of meatus, 0.669 for shape of meatus, 0.730 for shape of glans, and 0.708 for the shape of the skin. The lower agreement in the shape of the meatus evaluation may be attributed to the lack of a quantitative classification method in HOPE. Experts rely on their subjective judgment based on the provided example photos and their index patient. CONCLUSIONS: While there is high agreement among experts when evaluating hypospadias using the GMS and HOPE scoring criteria, only the position of the meatus achieved nearly perfect agreement highlighting that the current scoring systems entail a subjective element in disease classification.

Bladder Embryonal Rhabdomyosarcoma Presenting in the Perinatal Period: Report of Two Consecutive Cases.

Bladder embryonal rhabdomyosarcomas (ERMS) are malignant soft tissue tumors that rarely present in the perinatal period. Herein, we report 2 cases that were diagnosed in the newborn period (one with concomitant posterior urethral valves [PUV]), managed with chemotherapy and surgical resection to minimize the need for radiation.

Sentiment analysis of U.S. News & World Report Best Children's Hospital urology rankings: A difference in positivity between the public and academic worlds.

INTRODUCTION: Initiated in 2009, the U.S. News & World Report (USNWR) pediatric urology rankings aim to guide patients and families towards high-quality urologic care. Despite this, the pediatric urology community remains divided, with significant debate over the rankings' accuracy, utility, and potential for misleading information. While some professionals argue for a collective opt-out from these rankings, citing these concerns, others highlight their positive impact on patient care, hospital benchmarking, and financial support. OBJECTIVE: Recognizing the lack of formal evaluation on how these rankings are viewed beyond the pediatric urology community, this research endeavors to fill the gap through sentiment analysis of public news articles and academic publications. STUDY DESIGN: We captured news articles from Google News and academic papers from Ovid Medline and Embase, focusing specifically on content related to the USNWR pediatric urology rankings from 2009 to 2023. Sentiment analysis was conducted using the Valence Aware Dictionary and Sentiment Reasoner (VADER) package on both news and academic texts, aiming to capture the overall sentiment through a compound score derived from the presence of sentiment-laden words. Sensitivity analysis was performed using TextBlob Pattern Analyzer tool. RESULTS: The analysis revealed a significant divergence in sentiment between news articles and academic literature. News articles exhibited a predominantly positive sentiment, with an average compound score of 0.681, suggesting a general approval or celebration of the rankings in the public sphere. Conversely, academic literature showed a more moderate sentiment, with an average score of 0.534, indicating a nuanced perspective that includes both positive views and critical reflections on the rankings. Sensitivity analysis confirmed this observation (Figure). DISCUSSION: This difference may reflect the distinct nature of news media and academic discourse. While news outlets may prioritize celebratory narratives that align with public interest and institutional pride, academic discussions tend to offer a balanced view that critically assesses both the merits and limitations of the rankings. This discrepancy underscores the complexity of interpreting and acting upon the rankings within the pediatric urology community. CONCLUSION: While the USNWR pediatric urology rankings are generally received positively by the public, as reflected in news media, the academic community presents a more reserved sentiment. These findings suggest the need for ongoing dialogue and research to understand the implications of these rankings fully. It also calls for a strategic approach to address the concerns and perceptions of healthcare professionals, aiming to leverage the rankings in a way that truly benefits patient care and informed decision-making.

A scoping review on chordee correction in boys with ventral congenital penile curvature and hypospadias.

Introduction: Congenital penile curvature (PC), often concomitant with hypospadias, poses challenges in urology. Surgical correction techniques, including plication and corporotomy, lack standardized guidelines. This study aims to address the paucity of high-level evidence by comprehensively reviewing the outcomes of PC correction procedures in patients with and without hypospadias. This will inform clinical decision-making and provide insights for future research and meta-analyses. Methods: We conducted this scoping review in accordance with the JBI Manual for Evidence Synthesis and PRISMA-ScR guidelines. An extensive literature search was performed and comparative studies published in English up to June 2023 were included. The studies were divided into three categories: PC without hypospadias, PC with hypospadias, and studies comparing two or more materials for covering the ventral corporotomy. Data extraction comprised author details, patient characteristics, study design, interventions, outcomes, and complications. Methodological quality was assessed using the Newcastle-Ottawa Scale. Results: Forty-two studies were included in the review, which collectively comprised 3180 patients. Thirteen comparative studies reported the outcomes of surgery for congenital PC without hypospadias, 22 studies compared different techniques of PC correction in patients with hypospadias and 7 studies compared the type of materials for coverage following ventral corporotomy. In cases of PC without hypospadias, the most commonly reported surgery was the Nesbit's plication. For PC with hypospadias correction, the results of ventral corporotomy were superior to that of dorsal plication in most of the studies. The two-stage repair had better results when compared to the one-stage repair for patients with perineo-scrotal hypospadias. In studies comparing materials for coverage of ventral corporotomy, the tunica vaginalis flap or graft was utilized most commonly. The majority of the studies reported a success rate ranging from 85% to 100%. The methodological quality was high in all but four studies. Conclusion: Plication procedures are generally preferred for PC without hypospadias, but they result in penile shortening. For those with hypospadias, corporotomy is associated with superior outcomes than plication, especially for those with severe curvature and redo procedures. For ventral corporotomy coverage, the tunica vaginalis flap or graft is the most commonly reported tissue in the literature.

A study of correlation between premature ejaculation and lower urinary tract symptoms among Filipino males

OBJECTIVE: This study aimed to determine the association between Lower Urinary Tract Symptoms (LUTS) and premature ejaculation and define its prevalence and factors associated among Filipino males during the Annual National Digital Rectal Exam (DRE) day. METHODOLOGY: A descriptive cross sectional study was done in all male participants during the Annual National DRE day conducted at the Institute of Urology, St. Luke's Medical Center-Quezon City. All subjects were assessed by urologists for the presence of LUTS using the International Prostate Symptom Score (IPSS), and the Premature Ejaculation Diagnostic Tool (PEDT). The IPSS was categorized into total score (IPSS sum), storage symptoms (FUN - frequency, urgency, nocturia) and voiding symptoms (WISR - weak stream, intermittency, straining and residual urine). Ultrasound was also performed to obtain prostate size. The relationship between age, demographics, prostate size, IPSS scores, storage symptom score, voiding symptom score, and PEDT scores were analyzed using one way ANOVA. The statistical significance was set at P RESULTS: A total of 101 male participants were included in the study. Participants' age ranged from 36 to 86, with a mean age of 61 ±. The mean IPSS was 5.79 (±6.59 SD). The most common symptom is nocturia with prevalence of 32.7%. The prevalence of PE is 26.7% and 16.8% has probable PE. There are no associations between PE and age, LUTS, storage and voiding symptoms, prostate size and co-morbid illnesses such as hypertension and diabetes showing p values of 0.291, 0.226, 0.600, 0.108, 0.908, 0.954 and 0.833 respectively. However PE was associated with weak stream (P= 0.015) and educational attainment (P=0.008). CONCLUSION: Filipino men are becoming more concern about their health. LUTS are commonly seen in men in increasing age. PE is a very common male sexual dysfunction so there is a need for identification of such patients (17). Although, no correlation has been made between age, LUTS and PE in this study, however in further correlational analysis, educational status seems to have an impact in the self-reporting PE which may be due to higher awareness of participants with higher education. It is recommended that clinicians always utilize the screening questions for PE to give the appropriate treatment, since patients are often unwilling to volunteer their symptoms on PE (4.17). Our study also showed significant correlation with PE and weak stream, without association to prostate size. relating to a possible neurologic physiologic pathway rather than anatomic etiology of PE. Further study is recommended.

A prospective six-week randomized controlled trial on the efficacy and safety of sodium bicarbonate, citric acid, sodium citrate, and tartaric acid compound compared to potassium citrate in the dissolution of renal stones

OBJECTIVE: To determine the efficacy and safety of sodium bicarbonate, citric acid, sodium citrate, and tartaric acid (compound drug) in comparison to potassium citrate in the treatment of kidney stones. METHODS: Prospective randomized controlled trial of patients with kidney stones recruited from February to October 2011 at Out-patient Department was conducted. Ninety subjects, consented and eligible, were enrolled in this study. Random allocation of subjects into two groups was done using computer generated randomization. Subjects assigned to group I were treated with the compound drug(12 grams/day); while group II subjects were given potassium citrate(60mEq/day) for 6 weeks. Urinary pH levels were examined weekly and the effect of medical treatment on stone size changes was evaluated by ultrasonography every two weeks in the six-week treatment period. Intention to treat analysis was done with 95% confidence level(CI). Statistical analysis of results was determined using analysis of variance (ANOVA) with multiple repeated measures for between group urinary pH changes and chi square for between groups difference in stone size changes. RESULTS: A total of 74 subjects completed the study with a dropout rate of 18%, which was mainly due to geographic and financial reasons. Demographic and baseline stone characteristics of both groups were not significantly different. Treatment outcome between the two groups based on stone size changes (in general and both radiolucent and radioopaque stones subgroups) did not show any significant statistic difference. The pH level changes over six-week treatment period between the two groups showed a total mean pH difference of 0.445, (95% CI: 0.213, 0.677), which was statistically significant (P CONCLUSION:  Urinary alkalinization with sodium bicarbonate, citric acid, sodium citrate, and tartaric acid is a well-tolerated and highly effective treatment resulting in dissolution of non-obstructing kidney stones and is comparable to the gold standard potassium citrate.

Relationship of dietary intake of omega-3 and omega-6 fatty acids with risk of prostate cancer development: A meta-analyis of cohort studies

OBJECTIVE: To determine the relationship between dietary omega-3 fatty acid(n-3PUFA) and omega-6 fatty acids (n-6PUFA) with prostate cancer risk from a meta-analysis of prospective cohort studies. DESIGN: Cohort studies that investigated the relationship of dietary omega fatty acids and prostate cancer risk were retrieved from MEDLINE, Unbound MEDLINE, EMBASE, OVID, Cochrane Library and Science direct up to June 2011, and were critically appraised using Newcastle-Ottawa Quality Assessment for cohorts. General variance-based method was used to the pool the effect estimates at 95% confidence interval. Heterogeneity was assessed by chi square and quantified by I2. RESULTS: Eight cohort studies were included for meta-analysis. n-3PUFA, n-6PUFA and their derivatives were not significantly associated with risk of prostate cancer in general. A significant heterogeneity (P=0.023,I2=63%) between studies was noted. After inter-study variability adjustment was done, repeat analysis showed a significant negative association between high dietary intake of alpha-linolenic acid(ALA) and prostate cancer risk (pooled RR:0.915;95% CL:0.849, 0.985;P=0.019) Likewise, a slightly positive association was noted on dietary long chain omega-3 fatty acids (EPA+DHA) and prostate cancer risk (pooled RR: 1.135; 95% CI:1.008, 1.278 P=0.036), however when two other cohort studies with data of EPA and DHA both analyzed separately was included into the pool, the association became not significant (RR=1.034;95%CI:0.973,1.096;P=0.2780). CONCLUSION: The intake of n-3PUFA and n-6PUFA does not significantly affect the risk of prostate cancer. High intake of ALA may reduce risk of prostate cancer, while intake of long-chain omega-3 fatty acids does not have a significant effect.

Terpene compound drug as medical expulsive therapy for ureterolithiasis: A meta-analysis

OBJECTIVE: To investigate the efficacy of terpene compound drug (pinene, camphene, borneol, anethole, fenchone and cineol in olive oil) in facilitating spontaneous passage of ureteral calculiMETHODS: Systematic literature search of the MEDLINE, EMBASE, OVID, Science Direct, Proquest, Google scholar, Cochrane Library databases and rference lists of related literature was done without language restriction. Trials on ureterolithiasis medical expulsive therapy (MET) that compare terpene compound drug versus placebo/control group or alpha-blockers were identified. Articles retrieved were critically appraised by two independent reviewers according to Cochrane Collaboration recommendations. Data from included studies were extracted for calculation of risk ratio (RR) and 95% confidence interval (CI). Effect estimates were pooled using Mantel-Haenszel method with random effect model. Inter-study heterogeneity and publication bias were assessed. The PRISMA guidelines for meta-analysis reporting were followed.RESULTS: Five trials (total of 344 subjects) of adequate methodological quality were included. Pooled effect estimates from homogenous studies showed that compared to placebo/ control group, patients treated with terpene compound drug had significantly higher ureteral calculi expulsion rate (pooled RR: 1.34; 95% CI 1.12, 1.61). Analysis of studies that compare terpene compound drug with alpha-blockers showed no significant difference (pooled RR: 0.79; 95% CI 0.59, 1.06), although significant inter-study heterogeneity was noted. Only minor gastrointestinal adverse effect was reported on terpene compound drug use.CONCLUSIONS: The results suggest that terpene compound drug as MET is effective in promoting passage of ureterolithiasis. High quality large-scale RCTs comparing alpha-blockers and terpene compound drug are warranted to make a more definitive conclusion.
