Single dartos flap versus double dartos flap in hypospadias repair: A systematic review and meta-analysis with trial sequential analysis and fragility index.

INTRODUCTION: Hypospadias is a common congenital urogenital anomaly. Despite advancements in surgical techniques, still it presents challenges in management. An important aspect of hypospadias repair is the use of protective layers to cover neourethra. This review focuses on comparing the Single Dartos Flap (SDF) and Double Dartos Flap (DDF) techniques, used to cover the neourethra. These techniques differ in terms of the number of dartos layers used to cover the neourethra. METHODS: This systematic review, follows PRISMA guidelines, included six RCTs from PubMed/MEDLINE, Cochrane Library, Scopus, Web of Science, and CINAHL. Patients with hypospadias repair with use of SDF or DDF were analyzed for outcome, Urethrocutaneous fistula, meatal stenosis, glans dehiscence, penile torsion and cosmetic outcomes. Statistical analysis was done using Review Manager, with TSA and FI ensuring result robustness. RESULTS: Six studies met inclusion criteria, and risk of bias assessment indicated low risk across all domains. Meta-analysis results favored DDF over SDF for reducing urethrocutaneous fistula (RR 0.37, 95% CI 0.20-0.68) but showed no significant difference in meatal stenosis and glans dehiscence. DDF also associated with lower risk of penile torsion (RR 0.05, 95% CI 0.01-0.35). CONCLUSION: The systematic review, based on randomized controlled trials (RCTs), provides evidence supporting the use of DDF over SDF in hypospadias repair, particularly in distal hypospadias using the TIP procedure. The article emphasizes the potential advantages of DDF in reducing UCF but further robust evidence is needed to confirm these results based on the findings of TSA and FI.

Assessment of Antenatal and Postnatal Prognostic Indicators in the Outcome of Neonatal Congenital Diaphragmatic Hernia: A Prospective Observational Study.

Context: Despite advances in neonatal intensive care, surgical methods, and anesthesia, congenital diaphragmatic hernia (CDH) is still associated with significant mortality. Predicting which babies will have poorer outcomes is essential to identify the high-risk babies and to give targeted care and accurate prognosis to the parents, especially in a resource crunch set-up. Aims: The aim of this study is to evaluate the antenatal and postnatal prognostic factors in neonatal CDH that can be used to predict the outcome. Settings and Design: This was a prospective observational study in a tertiary care center. Subjects and Methods: Neonates presented with CDH within 28 days of life were included in the study. Bilateral disease, recurrent diseases, and babies operated outside were excluded from the study. The data were collected prospectively, and babies were followed until discharge or death. Statistical Analysis Used: Data were expressed in mean with standard deviation or median with range based on normality. All the data were analyzed using the SPSS software version 25. Results: Thirty babies with neonatal CDH were studied. There were three right-sided cases. The male-to-female ratio was 2.3:1, and 93% of babies were antenatally diagnosed. Seventeen out of the 30 babies underwent surgery. Nine (52.9%) underwent laparotomy, and 8 (47%) underwent thoracoscopic repair. Overall mortality was 53.3%, and operative mortality was 17.6%. Demographic characteristics were comparable between expired versus survived babies. The significant predictors of outcome identified were - Persistent pulmonary hypertension (PPHN), mesh repair, high-frequency oscillatory ventilation (HFOV), use of inotropes, 5-min APGAR, ventilator index (VI), and HCO3 levels. Conclusions: We conclude that the prognostic indicators associated with poor prognosis are low 5-min APGAR, high VI, low HCO3 levels in venous blood gas analysis, mesh repair, HFOV, inotropes usage, and PPHN. None of the antenatal factors studied showed any statistical significance. Further prospective studies with a larger sample size are recommended to confirm the findings.

Recurrent Hemangioma of the Penile Urethra - An Unusual Etiology of Gross Hematuria Managed Successfully with Holmium Laser Coagulation.

Urethral hemangioma is a benign uncommon vascular tumor. It presents with hematuria and macroscopic urethrorrhagia. Urethrocystoscopy is the main diagnostic modality. We share the case of a 14-year-old male child who presented with recurrent massive hematuria and was treated with urethra-cystoscopic holmium laser coagulation.

Management dilemma in pelvi-ureteric junction obstruction: is transit time the answer?

PURPOSE: Pelvi-ureteric junction obstruction (PUJO) is the leading cause for hydronephrosis in children. Diuretic renography used in the pre- and post-operative evaluation of pyeloplasty may not be reliable in predicting the outcome. METHODS: A prospective study was conducted from October 2018 to November 2020, including all children with unilateral PUJO undergoing Pyeloplasty. Renal diuretic renography scans done in the pre and post operative periods were assessed for transit time. The time taken for the isotope to reach the renal pelvis was noted by a single observer as the transit time, from the dynamic frames of the diuretic renogram. RESULTS: Of the 65 children, 74% were boys. The transit time (median) in the preoperative renography was 10 min, whereas the same was 4 min 45 s in the postoperative period, the decrease was statistically significant. On evaluation of transit time with ROC (receiver operating characteristics) curve, a cut-off of 4 min and 25 s was arrived at, which could identify the delayed drainage reliably. CONCLUSION: Improvement in transit time is a reliable predictor of renal function improvement after pyeloplasty, comparing favorably in relation to split renal function.

Utility of Urinary Biomarkers Neutrophil Gelatinase-Associated Lipocalin and Kidney Injury Molecule-1 as a Marker for Diagnosing the Presence of Renal Scar in Children with Vesicoureteral Reflux (VUR): A Cross-Sectional Study.

Aim: To explore the possibility of using urinary biomarkers neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) to assess the presence of renal scars in children with Vesicoureteric Reflux (VUR). Materials and Methods: This cross-sectional study was conducted in 94 children aged 0-16 years diagnosed with VUR in the Department of Pediatric Surgery, JIPMER. Urinary biomarkers were measured using the enzyme-linked immunosorbent assay kits, normalized with urinary creatinine (Cr) and compared with severity of VUR (low grade [I and II] and high grade [III, IV, and V]), presence or absence of renal scar in VUR patients and severity of renal scar. Independent Student's t-test, Mann-Whitney U-test, and analysis of variance Kruskal-Wallis test were used for comparison, and receiver operating characteristic (ROC) curve analysis for predicting the accuracy of biomarkers in detecting the presence of renal scars. Results: The median urinary NGAL (uNGAL) value was higher in children with renal scar (1.49 ng/mL) than those without renal scar (0.58 ng/mL) and was statistically significant (<0.001). Whereas median uNGAL/Cr was higher in children with renal scar (0.07) than those without renal scar (0.03) but was not statistically significant (P = 0.06). Urinary KIM-1 and urinary KIM-1/urinary Cr (uKIM-1/Cr) was not found to be a significant predictor of renal scar. The difference of uNGAL/Cr was comparable between the grades of renal scar but was not statistically significant. On ROC curve analysis, uNGAL had area under the ROC curve (AUC) of 0.769 with 71% of both specificity and sensitivity, whereas uNGAL/Cr was found to be a poor predictor of renal scar with AUC of 0.611, 60% sensitivity, and 61.2% specificity. Conclusion: uNGAL can serve as a noninvasive marker for diagnosing the presence of renal scar in children with VUR and a multicentric more extensive cohort study may be needed to strengthen or negate its role.

Calyx to Parenchymal Ratio (CPR): An unexplored tool and its utility in the follow-up of pyeloplasty.

INTRODUCTION: Antero-posterior trans pelvic diameter (APD) and renal scintigraphy play a significant role in the diagnosis of pelvi-ureteric junction (PUJ) obstruction and postoperative follow-up following pyeloplasty. However, the APD varies irrespective of improvement, deterioration, or preserved function in a hydronephrotic kidney and is not a reliable parameter due to various factors (hydration status, compliance, and reduction pyeloplasty). Calyx to Parenchymal Ratio (CPR) is the ratio of the depth of the calyx and parenchymal thickness measured on ultrasound (USG) in coronal image. We assessed the utility of CPR in the follow up of pyeloplasty and compared it with the commonly used APD of the pelvis and renal scintigraphy. MATERIAL AND METHODS: A prospective cohort study was done from July 2016 to October 2017. During this period 73 pyeloplasties were done, and 62 cases meeting the inclusion criteria were enrolled. All the children underwent ultrasound and Technetium-99 m Ethylene dicysteine isotope renogram (EC) scan before and after pyeloplasty. APD and CPR values were measured on USG and compared with isotope renogram outcomes in these children in the preoperative versus postoperative period. Two defined objective variables ΔAPD, percent ΔAPD and ΔCPR, percent ΔCPR were compared with categorical variables that would predict the surgical outcome as - failed, successful or equivocal. Multinomial logistic regression analysis and receiver operating curve (ROC) analysis was used to identify predictive accuracy. RESULTS: The mean (range) APD value recorded in the preoperative period was 3.67 cm (1.40-8.00 cm), which decreased to 1.67 cm (0.40-6.50) postoperatively, which was 54.2% lower (P=<0.001). The mean (range) CPR value decreased from 5.96 (1.20-20.00) in the preoperative period to 2.57 (0.43-10.90) postoperatively, which was 56.8% lower (P=<0.001). On multinomial logistic regression analysis, ΔCPR was found to be a significant predictor of outcome with an overall accuracy of 95.1%, change in CPR was a better predictor of success after pyeloplasty as compared to change in APD, which had an overall accuracy of 85.2% (p = 0.01). Further, on ROC curve analysis, we observed that ΔCPR and %ΔCPR can strongly predict successful pyeloplasty with a sensitivity of each with 96% and 98% respectively and AUC of 0.897 and 0.799 respectively. DISCUSSION: USG (APD) and renogram are the most widely used investigation in follow-up of pyeloplasty; however, APD has its own limitations like operator variability and slower improvement. CPR has the advantages that neither calyceal depth nor parenchymal thickness is directly altered during the surgery, and early resolution of calyceal dilatation and rapid parenchymal growth following pyeloplasty and thus a surgeon independent parameter. Our results have shown that ΔCPR can identify successful pyeloplasty with strong prediction than ΔAPD and thus renal scans can be avoided if there is visible improvement in CPR on follow-up. CONCLUSIONS: Our study identified a change in CPR, i.e., ΔCPR as a strong predictor of surgical outcome, as it is not influenced by extent of pelvis reduction during pyeloplasty and early to change. Using this parameter, we can avoid unnecessary repeated nuclear scans based on persistent high APD values and optimize resource utilization. We recommend the use of CPR in routine practice in the preoperative and postoperative follow-up of PUJ obstruction following pyeloplasty.

Metabolic and Clinical Characteristics of Children with Urolithiasis from Southern India.

OBJECTIVE: To study the etiological profile and patterns of clinical presentations of urolithiasis (UL) in children. METHODS: This observational study included patients <18 y with UL, who were referred to the pediatric nephrology clinic. Clinical features, family history, consanguinity and estimated glomerular filtration rate (eGFR) at presentation and follow-up were recorded. The children were evaluated using relevant blood and urine investigations. RESULTS: A total of 72 children with UL were evaluated for the study. The etiology of UL (n = 72) included hyperoxaluria (n = 25; 34.7%), idiopathic hypercalciuria (n = 21; 29.2%), idiopathic hyperuricosuria (n = 3; 4.2%), cystinuria (n = 3; 4.2%), urate transporter defect (n = 2; 2.8%) and mixed stones (predominant component calcium oxalate) (n = 9; 12.5%). No etiology was detected in 4 cases (5.5%). Common presenting complaints included flank pain (n = 41; 56.7%), hematuria (n = 29; 40.3%), urinary tract infection (UTI) (n = 29; 40.3%) and vomiting (n = 11; 15.3%). The median age of presentation was 60 (36, 96) mo. Family history and consanguinity were present in 30 cases (41.7%) and 28 cases (38.9%) respectively. Stone analysis was done in 20 cases, of which 9 cases were mixed stones (predominant calcium oxalate) and 6 were calcium oxalate stones. CONCLUSIONS: Among children with urolithiasis, hyperoxaluria, idiopathic hypercalciuria, idiopathic hyperuricosuria, and cystinuria were the predominant identifiable entities, together accounting for 72% of cases; and renal colic, hematuria and UTI were the commonest clinical complaints.

High grade renal trauma due to blunt injury in children: do all require intervention? / Trauma renal de alto grau devido a lesão contusa em crianças: será que todas necessitam intervenção?

ABSTRACT Introduction: The aim of this study was to analyze the presentation and management of major grade renal trauma in children. Method: A retrospective study was performed including data collected from the patients who were admitted in Pediatric surgery with major grade renal injury (grade 3 and more) from January 2015 to August 2018. Demography, clinical parameters, management, duration of hospital stay and final outcome were noted. Results: Out of 13 children (9 males and 4 females), with age range 2-12 years (mean of 8 years), reported self-fall was the commonest mode of injury followed by road traffic accident. The majority (10/13, 75%) had a right renal injury. Eight children had a grade IV injury, one had a grade V injury, and four children had grade III injury. Duration of hospital stay varied from 3 to 28 (mean of 11.7) days. Three children required blood transfusion. One child required image guided aspiration twice and two required pigtail insertion for perinephric collection. All the 13 children improved without readmission or need for any other surgical intervention. Conclusion: Children with major grade renal trauma due to blunt injury can be successfully managed without surgical intervention and minimal intervention may only be needed in select situations.

RESUMO Introdução: O objetivo deste estudo foi analisar a apresentação e tratamento de grande trauma renal em crianças. Método: Foi realizado um estudo retrospectivo incluindo dados coletados dos pacientes que foram internados na cirurgia pediátrica com lesão renal de grau importante (grau 3 ou mais) de janeiro de 2015 a agosto de 2018. Coletamos dados a respeito de demografia, parâmetros clínicos, manejo, tempo de internação e resultado final. Resultados: Das 13 crianças (9 homens e 4 mulheres) com faixa etária de 2-12 anos (média de 8 anos), a queda auto-relatada foi o modo de lesão mais comum seguido de acidente de trânsito. A maioria (10/13, 75%) apresentou lesão renal direita. Oito crianças tiveram uma lesão grau IV, uma apresentou uma lesão grau V e quatro crianças apresentaram lesão grau III. A duração da internação hospitalar variou de 3 a 28 (média de 11,7) dias. Três crianças necessitaram de transfusão de sangue. Uma criança necessitou de aspiração guiada por imagem duas vezes e duas inserções de dreno pigtail exigidas para coleções perinefréticas. Todas as 13 crianças melhoraram sem re-internação ou necessidade de qualquer outra intervenção cirúrgica. Conclusão: Crianças com trauma renal de alto grau devido a lesão contusa podem ser manejadas com sucesso sem intervenção cirúrgica, e intervenção mínima pode ser necessária apenas em situações selecionadas.

Fetus in Fetu: Case Report and Brief Review of Literature on Embryologic Origin, Clinical Presentation, Imaging and Differential Diagnosis.

BACKGROUND: Fetus in fetu (FIF) is a rare entity in which a malformed diamniotic monochorionic parasitic fetal twin develops inside a normal co-twin's body, most commonly in the abdominal cavity. FIF is differentiated from the teratoma by the presence of vertebral column often with an appropriate arrangement of other organs or limbs around it. CASE REPORT: A two-and-a-half-year-old girl presented with a painless abdominal swelling in the right hypochondrium. On imaging, a heterogenous soft tissue mass with internal calcific densities was noted in the retroperitoneum. The mass had vertebral organization, limb and pelvic bones. The presence of a fetiform teratoma was suspected and surgery revealed an encapsulated mass with an anencephalic head, spine, upper and lower limb buds. Histopathology confirmed the presence of a fetus in fetu. The postoperative period was uneventful with no evidence of recurrence. CONCLUSIONS: FIF is a pediatric rarity. Cross-sectional imaging helps in differentiating it from a teratoma, meconium peritonitis and abdominal ectopic pregnancy. Surgical excision is the treatment of choice for this benign condition, which requires a follow-up only in certain cases. This case report describes a retroperitoneal fetus in fetu and discusses its clinical presentation, differential diagnosis and embryologic origin.

Transanal impalement of double J steel bar with colonic and jejunal injury: A unique pediatric case report.

Pediatric transanal impalement injuries are relatively uncommon and most are attributed to accidental fall on offending objects, sexual assault or blunt trauma. There may be difficulty in recognizing or properly treating such injuries because their severity may not be reflected externally. Evaluation of suspected rectal impalement injury involves careful history and physical examination and proper investigation. There are very few reports on pediatric perianal impalement with associated visceral injuries. We report a case of assault transanal impalement injury associated with mesenteric tear and jejunal perforation leading to devitalization of proximal jejunum in a 2 year male child and relevant literatures were reviewed. To the best of our knowledge, such dual proximal and distal gastrointestinal injury in such a small child has not been reported in any of the English literature so far.

Portal teratoma causing obstructive jaundice in children: a rarity.

Teratoma in children is a common entity, usually occurring both in gonadal and extragonadal sites. Common extragonadal sites for teratoma in children are the sacrococcygeal region, retroperitoneum, and mediastinum. Various unusual extragonadal sites have been reported. However, teratoma in the hepatoduodenal ligament is a very rare occurrence. We herein report a case of a mature teratoma in the hepatoduodenal ligament in an 11-year-old child presenting with obstructive jaundice along with its surgical management and review of the literature.

Primary hydatid cyst masquerading as pseudocyst of the pancreas with concomitant small gut obstruction--an unusual presentation.

Isolated retroperitoneal hydatid cyst is an exceptionally rare entity. Owing to vague and varied symptomatology, it is seldom diagnosed without puncture cytology or surgery. We report an unusual presentation of primary retroperitoneal hydatid cyst with concomitant small gut obstruction. Ultrasonography and computed tomography of the abdomen showed localized abscess or pseudocyst of pancreas. Preoperatively, ultrasound-guided puncture cytology of the lesion revealed suspicious hydatid pathology. The patient was examined and, peroperatively, the cyst masqueraded as hydatid cyst of pancreas along with an inflammatory band, and the diagnostic dilemma about its exact site of origin was solved by histopathology only. Complete excision of the cyst along with the tail of pancreas was done with concomitant excision of inflammatory band, causing small intestinal obstruction. The patient was discharged in satisfactory condition on albendazole. In follow-up of 8 months, there was no recurrence.

Xanthogranulomatous cholecystitis: case series in a rural area, clinicopathological study and review of literature.

Xanthogranulomatous cholecystitis is a destructive inflammatory disease of the gallbladder, rarely involving adjacent organs and mimicking an advanced gallbladder carcinoma. The diagnosis is usually possible only after pathological examination. We are reporting two of such rare cases in female patients attending our institute. In both patients xanthogranulomatous cholecystitis was diagnosed on histopathology.

Lumbocostovertebral syndrome with associated VACTERL anomaly.

Lumbocostovertebral syndrome is a rare clinical association syndrome rarely accompanied by associated VACTERL anomalies. Only one similar case has been reported previously. We describe the second case, where a male neonate born at 38 weeks of gestation had an unusually high number of congenital anomalies including thoracic hemivertebrae with kyphoscoliosis, a high anorectal malformation, dextrocardia with an atrial septal defect, renal pelvic pyelectasis, hypospadias, and congenital talipes equinovarus.
