Neonatal jaundice is associated with increased risks of congenital anomalies of the kidney and urinary tract and concomitant urinary tract infection.

The link between neonatal jaundice and urinary tract infection (UTI) remains debated, with congenital kidney and urinary tract anomalies (CAKUT) potentially playing a role. This population-based study aimed to analyze the correlations between neonatal jaundice, CAKUT, and concomitant UTI. The study cohort consisted of 2,078,122 live births from 2004 to 2014. We linked several population-based datasets in Taiwan to identify infants with unexplained neonatal jaundice and their mothers. The primary outcome was the rate of CAKUT occurring within 3 years after delivery, and the presence of concomitant UTI during neonatal jaundice hospitalization. Infants with neonatal jaundice had a significantly higher risk of CAKUT (adjusted odds ratio [aOR] 1.24, 95% confidence interval [CI] 1.11-1.39) during early childhood. Among the subtypes of CAKUT, obstructive uropathy, vesicoureteral reflux and other CAKUT were associated with an increased risk of neonatal jaundice. Infants who underwent intensive phototherapy, had a late diagnosis (> 14 days of postnatal age) or underwent a prolonged duration of phototherapy (> 3 days) exhibited a higher risk of concomitant UTI compared to other infants with jaundice. Our findings indicate a notable association between neonatal jaundice and increased risks of UTIs in the context of CAKUT. This study underscore the importance of vigilant monitoring and timely interventions for neonates presenting with jaundice, while acknowledging the complexity and variability in the progression of CAKUT and its potential connection to UTIs.

Deep learning prediction of renal anomalies for prenatal ultrasound diagnosis.

Deep learning algorithms have demonstrated remarkable potential in clinical diagnostics, particularly in the field of medical imaging. In this study, we investigated the application of deep learning models in early detection of fetal kidney anomalies. To provide an enhanced interpretation of those models' predictions, we proposed an adapted two-class representation and developed a multi-class model interpretation approach for problems with more than two labels and variable hierarchical grouping of labels. Additionally, we employed the explainable AI (XAI) visualization tools Grad-CAM and HiResCAM, to gain insights into model predictions and identify reasons for misclassifications. The study dataset consisted of 969 ultrasound images from unique patients; 646 control images and 323 cases of kidney anomalies, including 259 cases of unilateral urinary tract dilation and 64 cases of unilateral multicystic dysplastic kidney. The best performing model achieved a cross-validated area under the ROC curve of 91.28% ± 0.52%, with an overall accuracy of 84.03% ± 0.76%, sensitivity of 77.39% ± 1.99%, and specificity of 87.35% ± 1.28%. Our findings emphasize the potential of deep learning models in predicting kidney anomalies from limited prenatal ultrasound imagery. The proposed adaptations in model representation and interpretation represent a novel solution to multi-class prediction problems.

Evolución de niños con anomalías del tracto urinario y propuesta de interrupción del embarazo / Progress of children with urinary tract anomalies and proposal of pregnancy cessation

Introducción: el ultrasonido diagnóstico prenatal realizado en los embarazos normales ha demostrado que por cada 500 embarazos debe aparecer una anomalía importante del tracto urinario. En diferentes situaciones puede sugerirse o recomendarse la interrupción del embarazo, que puede ser aceptado o rechazado por los padres. Objetivos: comparar el diagnóstico pre y posnatal, y valorar la evolución en 8 pacientes en los que se propuso la interrupción, pero el embarazo continuó. Resultados: en 6 de los fetos se propuso la interrupción por el diagnóstico de hidronefrosis bilateral; en uno, por quistes renales bilaterales, y en otro por hidronefrosis unilateral y displasia renal multiquística contralateral. En 2 recién nacidos hubo coincidencia total entre el diagnóstico prenatal y el posnatal, en uno con reflujo de alto grado se encontró ureterohidronefrosis bilateral en el estudio prenatal, mientras que en 2 solamente hidronefrosis; un paciente tiene megauréter bilateral no obstructivo, y otro pielectasia bilateral. En el feto que se plantearon los quistes renales bilaterales, el estudio posnatal mostró un doble sistema excretor derecho con el superior obstruido, y reflujo vesicoureteral grado III del inferior con riñón izquierdo normal. Durante el tiempo de seguimiento la conducta médica varió de acuerdo con el diagnóstico posnatal. Al concluir el período de seguimiento, un paciente tiene una enfermedad renal crónica etapa 3, y los 7 restantes tienen función renal conservada. Conclusiones: la indicación de interrupción del embarazo por el diagnóstico ultrasonográfico prenatal de una anomalía renal o de tracto urinario tiene un margen de error que es necesario seguir estudiando y buscar indicadores de alto riesgo vital, porque los factores predictivos no están bien precisados(AU)

Introduction: prenatal ultrasound diagnosis performed in normal pregnancies has shown that one significant urinary tract anomaly occurs per 500 pregnancies. Under different circumstances, termination of pregnancy may be suggested or recommended, which may be accepted or rejected by parents. Objectives: to compare the pre-and postnatal diagnoses, and to assess the progress in 8 patients who were recommended to terminate their pregnancies, but they rejected this idea. Results: in 6 cases, the termination of pregnancy was suggested on account of bilateral hydronephrosis diagnosis in their fetuses; in one case due to bilateral renal cysts diagnosis and in the other case due to unilateral hydronephrosis and contralateral multicystic renal dysplasia. There was full agreement between the prenatal and postnatal diagnoses in 2 newborns; in a neonate with high grade reflux, the prenatal study revealed bilateral ureterohydronephrosis whereas this study showed just hydronephrosis for other two fetuses. One patient has non-obstructive bilateral megaureter and the other presents bilateral pyelectasy. The fetus with bilateral renal cysts presented, according to the postnatal study, a double right excretory system, being the upper obstructed and the lower with grade III vesicoureteral reflux, but his left kidney was normal. In the follow-up period, the medical behavior varied according to the postnatal diagnoses. Upon finishing this period, one patient had phase III chronic renal disease and the other seven had preserved renal function. Conclusions: the indication of termination of pregnancy based on the prenatal ultrasonographic diagnosis of a renal or urinary tract anomaly has an error index that must be further studied, and it is necessary to look for high life risk indicators because the predictive factors are not well detailed(AU)

Diagnóstico y evolución de las malformaciones congénitas del Riñón y las Vías Urinarias. 1999-2005.Holguín.2007 / Diagnosis and evolution of congenital malformations of the kidney and urinary tract

Con el objetivo de evaluar la experiencia clínica en los Servicios de Nefrología y Urología del Hospital Pediátrico Provincial Docente Octavio de Concepción y de la Pedraja de Holguín se realizó un estudio descriptivo de 351 pacientes atendidos entre enero 1999 y diciembre 2005. En esta serie de 351 pacientes fueron diagnosticadas 535 malformaciones congénitas del riñón y vías urinarias de 19 tipos. El reflujo vesico ureteral primario, la estenosis de la unión ureteropiélica y el doble sistema excretor fueron en ese orden, las malformaciones más frecuentes, siendo la edad más común de diagnóstico durante el primer año de vida. La mayoría de los pacientes se presentaron con infección del tracto urinario y un número importante fueron asintomáticos. La ultrasonografía y la uretrocistografía miccional convencional resultaron una combinación efectiva para el diagnóstico de estas. La mayoría de los pacientes a los que se les realizó diagnóstico prenatal tenían una Hidronefrosis Congénita. La valva de uretra posterior fue la principal causa de insuficiencia renal crónica. Los grados I, II y III de reflujo vesico ureteral primario casi siempre desaparecen espontáneamente, siendo el tratamiento médico o conservador la piedra angular en el manejo de estos pacientes. Apreciamos una relación directa entre la nefropatía de reflujo y el grado de esta entidad. (AU)

Improvement of continence with reoperation in selected patients after surgery for anorectal malformation.

PURPOSE: Fecal incontinence is a serious complication after repair of anorectal malformations. We investigated whether reoperation can improve fecal continence. METHODS: Medical records of 41 patients (40 children and one adult; 26 male and 15 female) who underwent reoperation after previous reconstruction of an anorectal malformation were reviewed for outcomes of bowel function. Type of primary corrective surgery performed, therapeutic measures, results of physical examination and barium enema, and reoperation procedures were evaluated. A questionnaire was administered to assess stool behaviour and level of continence at follow-up three or more years after secondary operation. RESULTS: Secondary operations in males comprised posterior sagittal anorectoplasty (PSARP) in 16 patients, PSARP with antegrade continent enema in one patient, antegrade continent enema alone in 6, anoplasty in one, rectosigmoid resection in 1, and definitive colostomy in 1 patient. Secondary operations in females included PSARP alone in 4 patients, PSARP with total urogenital mobilization in 4, PSARP with vaginoplasty in 2, PSARP with vaginoplasty and antegrade continent enema in 2, and PSARP with vaginourethroplasty in 3. Of 41 patients 18 (44 percent) were continent at follow-up, 21 (51 percent) were clean with use of enemas, diet, or drug therapy. One patient had a definitive colostomy. One died after kidney transplantation. CONCLUSIONS: Surgery is a good option for improving incontinence in selected patients previously operated for anorectal malformations. Posterior sagittal anorectoplasty is advocated to improve bowel control. Antegrade continent enema is a reliable therapeutic option to maintain clean patients with fecal incontinence.

Pseudohypoaldosteronisms, report on a 10-patient series.

BACKGROUND: Type 1 pseudohypoaldosteronism (PHA1) is a salt-wasting syndrome caused by mineralocorticoid resistance. Autosomal recessive and dominant hereditary forms are caused by Epithelial Na Channel and Mineralocorticoid Receptor mutation respectively, while secondary PHA1 is usually associated with urological problems. METHODS: Ten patients were studied in four French pediatric units in order to characterize PHA1 spectrum in infants. Patients were selected by chart review. Genetic, clinical and biochemistry data were collected and analyzed. RESULTS: Autosomal recessive PHA1 (n = 3) was diagnosed at 6 and 7 days of life in three patients presenting with severe hyperkalaemia and weight loss. After 8 months, 3 and 5 years on follow-up, neurological development and longitudinal growth was normal with high sodium supplementation. Autosomal dominant PHA1 (n = 4) was revealed at 15, 19, 22 and 30 days of life because of failure to thrive. At 8 months, 3 and 21 years of age, longitudinal growth was normal in three patients who were given salt supplementation; no significant catch-up growth was obtained in the last patient at 20 months of age. Secondary PHA1 (n = 3) was diagnosed at 11, 26 days and 5 months of life concomitantly with acute pyelonephritis in three children with either renal hypoplasia, urinary duplication or bilateral megaureter. The outcome was favourable and salt supplementation was discontinued after 3, 11 and 13 months. CONCLUSIONS: PHA1 should be suspected in case of severe hyperkalemia and weight loss in infants and need careful management. Pathogenesis of secondary PHA1 is still challenging and further studies are mandatory to highlight the link between infection, developing urinary tract and pseudohypoaldosteronism.

Time courses of bacterial density in urine during antibacterial chemotherapy and influential factors in patients having positive bacteriuria with a complicated urinary tract.

A series of consecutive urine cultures was performed to determine the time points of elimination of bacteria from urine and the factors influencing these time points in patients receiving antimicrobial chemotherapy for positive bacteriuria. Between 1988 and 2000, 110 patients who had positive bacteriuria and received a 5-day regimen of parenteral antibacterials were included in this study. Quantitative urine cultures were performed every 24 h throughout the therapy. Bacteria were identified; minimum inhibitory concentrations of antibacterial agents for causative bacteria were determined, and the bacteria were categorized as susceptible or nonsusceptible. The complexity of the urinary tract was graded as high or low. A multivariate Cox proportional hazards model was utilized to identify the factors that determined the time course of bacterial density in urine. Two penicillins, seven cephalosporins, five carbapenems and one fluoroquinolone were administered to 110 patients. The overall bacteriurial elimination rate at the end of treatment was 73% (80/110), and the most frequent day of elimination was day 1 (54%; 43/80), followed by day 2 (20%; 16/80). The significant factors for persistence of bacteriuria after chemotherapy were the presence of an indwelling catheter, a nonsusceptible pathogen, and high complexity of the urinary tract; risk ratios were: 2.398 (P = 0.0009), 2.227 (P = 0.0020), and 2.113 (P = 0.0455), respectively, which also influenced the day of elimination. In conclusion, the efficacy of treatment and the time point of bacteriurial elimination were determined by the presence of a urinary catheter, drug susceptibility, and urinary complexity in patients with positive bacteriuria undergoing antibacterial chemotherapy.

Folate intake and the primary prevention of non-neural birth defects.

OBJECTIVES: To investigate whether maternal periconceptional folate intake is associated with a reduction in selected non-neural birth defects in Western Australia (WA). METHODS: Case-control study of folate intake in women whose infants had orofacial clefts (62); congenital heart defects (151); urinary tract defects (117); limb reduction defects (26); or other major birth defects (119); and 578 control women. RESULTS: Neither folic acid supplements nor dietary folate intake in women not using supplements was significantly associated with a reduction in risk in any of the case groups. In contrast to neural tube defects, WA population data for orofacial clefts, heart defects, limb reduction defects and urinary tract defects showed no fall in prevalence since the introduction of folate promotion and voluntary food fortification. CONCLUSIONS: This study provides no evidence of folate being an important factor in the prevention of birth defects other than neural tube defects.

[Recurrent urinary tract infections]. / Infecciones urinarias recurrentes.

Recurrent urinary tract infections (RUTI) are a frequent clinical problem in sexually active young women, pregnant or postmenopausal women and in patients with underlying urological abnormalities. The present chapter reviews RUTI based on their classification: relapses, which usually occur early (< 1 month), are caused by the same microorganism and are associated with underlying urological abnormalities, and reinfections, which usually occur later and are caused by a new distinct microorganism (or by the same microorganism usually located in the rectum or uroepithelial cells). The pathogenesis of RUTI is reviewed and the risk factors associated with RUTI in premenopausal women (usually related to sexual activity), postmenopausal women (in whom estrogen deficiency has a significant effect on the vaginal Lactobacillus flora), and in pregnant women are discussed. Likewise, an extensive review of the distinct therapeutic strategies to prevent RUTI is provided: self-treatment of cystitis, continuous antibiotic prophylaxis, postcoital antibiotic prophylaxis, topical vaginal estrogens, Lactobacillus, cranberry juice, intravesical administration of non-virulent E. coli strains and vaccines, among others. Several diagnostic-therapeutic algorithms are included. These algorithms are based on the type of urinary infection (relapse-reinfection), on the type of patient (young, postmenopausal, or pregnant women) and on the number of episodes of RUTI.

Medical management of congenital anomalies of the kidney and urinary tract.

Renal damage in children has been found to be more congenital in origin than was previously thought. Congenital anomalies of the kidney and urinary tract (CAKUT) involve renal dysplasia, renal hypoplasia, urinary tract obstruction and vesicoureteral reflux. CAKUT are sometimes bilateral and different types often coexist. Depending on their types and severity, children with CAKUT often have varying degrees of a reduced number of nephrons at birth. CAKUTare now the leading cause of renal failure in children. Children with renal dysplasia or obstructive uropathy may have abnormal renal tubules, and tend to lose essential water and sodium in urine. This can lead to poor body growth unless they are supplemented with water and sodium. Children with severe ureteric reflux often develop urinary infection and renal scarring. Renal scarring can further increase the risk of renal failure in children who already have other CAKUTand fewer nephrons than normal. Hypertension and proteinuria may develop in children with renal dysplasia and further aggravate renal function unless they are treated. Recent advances in the understanding and management of CAKUT make it possible for children with CAKUT to grow normally, have fewer complications such as urinary infection, have longer renal survival, and survive even with end-stage renal diseases through renal replacement therapy.

Geographic and temporal analysis of folate-sensitive fetal malformations.

OBJECTIVE: To identify potential geographic and temporal clustering of folate-sensitive fetal malformations as a prelude to a targeted preconception curriculum in folic acid supplementation. METHODS: Our comprehensive prenatal anomaly database was queried to select fetal malformations presumed to be sensitive to preconception folate insufficiency. Evidence of geographic clustering was evaluated by distribution of individual cases using zip codes of maternal residence. Potential temporal clustering of anomalies was sought by tabulating the frequency of each anomaly category during 5 consecutive 2-year intervals between 1992 and 2001. RESULTS: Over a 10-year period, approximately 2000 fetal anomalies were identified, of which 400 (20%) were considered potentially folate sensitive. We found geographic clustering of ventral wall defects as well as obstructive uropathy by zip code analysis. Significant increases in the frequencies of cardiac defects (P <.001) and obstructive uropathy (P <.001) were noted during the epoch of this study. A moderate increase in anomaly frequency was also seen in the diagnostic subcategory of gastroschisis, in which 15 of 27 total gastroschisis cases occurred in 2000-2001. CONCLUSIONS: Geographic clustering and temporal trends in anomaly rates were noted in certain folate-sensitive malformation categories. Identification of specific, high-incidence regions may provide an opportunity for targeted interventions designed to supplement the national folic acid campaign.

Folic acid antagonists during pregnancy and the risk of birth defects.

BACKGROUND: Multivitamin supplementation in pregnant women may reduce the risks of cardiovascular defects, oral clefts, and urinary tract defects in their infants. We evaluated whether the folic acid component of multivitamins is responsible for the reduction in risk by examining the associations between maternal use of folic acid antagonists and these congenital malformations. METHODS: We compared data on exposure to folic acid antagonists that act as dihydrofolate reductase inhibitors and to certain antiepileptic drugs for 3870 infants with cardiovascular defects, 1962 infants with oral clefts, and 1100 infants with urinary tract defects with data for 8387 control infants with malformations the risk of which is not reduced after vitamin supplementation. Mothers were interviewed within six months after delivery about their medication use. RESULTS: The relative risks of cardiovascular defects and oral clefts in infants whose mothers were exposed to dihydrofolate reductase inhibitors during the second or third month after the last menstrual period, as compared with infants whose mothers had no such exposure, were 3.4 (95 percent confidence interval, 1.8 to 6.4) and 2.6 (95 percent confidence interval, 1.1 to 6.1), respectively. The relative risks of cardiovascular defects, oral clefts, and urinary tract defects after maternal exposure to antiepileptic drugs were 2.2 (95 percent confidence interval, 1.4 to 3.5), 2.5 (95 percent confidence interval, 1.5 to 4.2), and 2.5 (95 percent confidence interval, 1.2 to 5.0), respectively. Use of multivitamin supplements containing folic acid diminished the adverse effects of dihydrofolate reductase inhibitors, but not that of antiepileptic drugs. CONCLUSIONS: Folic acid antagonists, which include such common drugs as trimethoprim, triamterene, carbamazepine, phenytoin, phenobarbital, and primidone, may increase the risk not only of neural-tube defects, but also of cardiovascular defects, oral clefts, and urinary tract defects. The folic acid component of multivitamins may reduce the risks of these defects.

Malformaciones del aparato urinario en recién nacidos de la maternidad Hospital Clínico de la Universidad de Chile / Urinary tract malformations in the department of obstetrics of the Universidad de Chile clinical hospital, in the period 1982-1997

Background: The prevalence of urinary malformations at birth is steadily increasing, probably due to the availability of better diagnostic techniques Aim: To assess the prevalence of renal agenesis, hidroureteronephrosis and polycystic kidney at birth in the obstetric wards of the University of Chile Clinical Hospital. Patients and methods: As a part of the Latin American Collaborative Study of Congenital Malformations, 54.039 consecutive births at the Maternity, between January 1982 and December 1997, were studied. Results: Eighty three newborns had urinary tract malformations (15.3/10000). Fourteen (2.6/10000) had renal agenesis, 34 (6.3/10000) had hidroureteronephrosis and 35 (6.5/10000) had polycystic kidney. Eleven percent of these children were stillbirths and 35 percent died in the first days of life. Fifty six percent were male, 34 percent female and 10 percent had ambiguous sex. Mean birth weight was 2750 g, mean gestational age was 35.4 weeks and mean maternal age was 28 years old. Twenty three percent of mothers had a history of previous abortions, 8 percent had a history of stillbirths and 10 percent a history of metrorrhagia during the first trimester of pregnancy. Twenty five percent of children had a relative with a malformation and 48 children had other associated malformations such as pulmonary hypoplasia, external malformations caused by extreme oligoamnios or internal malformations such as utereral, urinary bladder, uretral or external genitalia agenesis. Conclusions: The prevalence of urinary malformations in this hospital was higher than in other hospitals participating in the collaborative study. This difference could be due to an under registration of malformations in other hospitals

Adult patients with spina bifida cystica: genetic counselling, pregnancy and delivery.

With more aggressive surgical management, patients born with spina bifida may now reach adulthood and achieve pregnancies. Any female patient with spina bifida is strongly recommended to have preconceptional genetic counselling. The risk for parents with spina bifida of having affected offspring (approx. 4%) is considerably increased compared with the general population (0.1-0.3%). This risk may be lowered when periconceptional folic acid supplements are given. In pregnancy, special care is needed in the management of urological, obstetric, neurological and anaesthetic problems. Urological complications like neurogenic bladder, incontinence, chronic infection, increased chance of developing bladder carcinoma and impaired renal function are common in the spina bifida patient. In case of urinary diversion, obstruction may complicate the pregnancy. The incidence of premature labour is increased. Clinical assessment of the pelvis is necessary because of a possibly contracted pelvis. If the head engages normally, vaginal delivery should be allowed if possible. Caesarean section should be performed for obstetric reasons only. Cerebrospinal fluid shunts may give neurological problems during pregnancy. In most cases reported, symptoms improved spontaneously after delivery. In case of a shunt, vaginal delivery is preferable, pushing during second stage not contra-indicated, and in case of caesarean section, prophylactic antibiotics and thorough irrigation of the peritoneal cavity are indicated.

[Brulamycin in the treatment of urinary infections--microbiological and clinical research]. / Brulamitsin za lechenie na uroinfektsiite--mikrobiologichni i klinichni prouchvaniia.

The authors report the results frop microbiological and clinical studies of the new aminoglucoside antibiotic brulamycin. The susceptibility of 12 392 bacterial strains was determined versus brulamycin and the other routinely applied antibacterial preparations in our country and established that, according to that index brulamycin, in vitro, gives way only to amikin. Fifty two patients with severe uroinfections were treated (30 adults and 22 children) and healing (sterilization of urine) was attained in 10 per cent of the adults and 40,9 per cent of the children. Improvement (reduction of the bacterial number to insignificant value) was established in 42,3 per cent of all patients. In parallel with the favourable microbiological indices, improvement or normalization of the clinical and paracminical indices of the uroinfection were also established. The antibiotic is very well tolerated, by children one-year of age, including. With those properties brulamycin should widely be administered in the clinical practice of uroinfection treatment.
