Resumen

Uretero-inguinal hernia in patients with native kidneys is rare. We report a case of an 84-year-old man who was diagnosed with obstructive uropathy secondary to uretero-inguinal hernia, with no past history of herniorrhaphy or congenital genitourinary malformation. Uretero-inguinal hernias are predominantly indirect inguinal hernias and may be paraperitoneal or extraperitoneal. Computed tomography (CT) is a non-invasive diagnostic tool for uretero-inguinal hernia. Herniorrhaphy is indicated in all cases of uretero-inguinal hernia to prevent obstructive uropathy.

Resumen

Background: Anorectal malformations are congenital anomalies characterized by the absence of a normally formed anus. Obstructive uropathy, vesicoureteral reflux neurovesical dysfunction are the leading causes of mortality and morbidity in ARM. Early diagnosis and treatment of NVD prevents renal parenchymal damage.Surgical interventions for the correction of anorectal malformation may also lead to the development of NVD. The incidence of urologic and spinal anomalies associated with ARM and the relationship between the anorectal malformations, spinal abnormalities and voiding dysfunction was studied by means of MRI spine and urodynamic studies. Methods: A prospective, observational study was done over a period of 2 years. All patients with ARM underwent MRI of the spine, ultrasound of abdomen, micturating cystourethrogram and urodynamic study.Results: Forty two patients were included in this study. Out of the 42 patients 17 (40.5%) were female and 25 (59.5%) were male. The ages of the patients ranged from 4 months to 14 years with an average of 32.9 months. 5 patients (12%) had complaints pertaining to neurovesical dysfunction. MRI of the spine revealed abnormalities in 10 patients (23.8%). Urodynamic study was abnormal in 8 patients (19%). Therefore a total of 8 patients (19%) had neurovesical dysfunction in the present study. This included 3 female patients with cloaca and 5 male patients with high anorectal malformations.Conclusions: Neurovesical dysfunction is frequently seen in patients with anorectal malformations. NVD may be due to the spinal abnormalities or due to iatrogenic injuries to the bladder innervations during surgical reconstruction.

Resumen

To study epidemiological and diagnostic aspects of urinary tract infection (UTI) in newborns at the Departmental Teaching Hospital of Borgou-Alibori (DTH-B/A). This was a cross-sectional study conducted from April 1, 2019 to September 30, 2019 and concerned all newborns admitted to the neonatal unit of DTH-B/A. According to the National Agency for Health Accreditation and Evaluation (NAHAE)recommendations of 2002, all symptomatic newborns who did not have a visible malformation outside the genitourinary system and whose parents gave their consent were included in the study. The census was exhaustive despite the calculated minimum size of 109 newborns. Urine sedimentation and cytobacteriological examination of urine samples, taken in adhesive bags after local disinfection, demonstrated presence of pathogenic microbes. Sensitivity of detected microbes was studied to different antibiotics. Interpretive reading of antibiograms was established according to the Standards of the French Society of Microbiology (FEMS), edition 2012. If UTI was confirmed, an abdominopelvic ultrasound was performed in search for a malformative uropathy as a contributing factor in newborns. A standardized survey was developed for data collection. The data entered were analyzed using the Epi info software, version 3.5.4. In all, 124 newborns were included in the study. UTI accounted for 8.06% of all neonatal infections and 2.15% of admissions. The average age of onset was 7.8 days, with a gender ratio of 1:1. The main clinical manifestations were jaundice and respiratory distress. Microbes involved were Staphylococcus aureus (6/10), Escherichia coli (2/10), and Klebsiella oxytoca (2/10). The resistance of microbes to antibiotics was generally high. No abnormalities were revealed in the ultrasound. Although neonatal UTI is not a rare infection, bacterial resistance is of concern.

Resumen

Introduction: The OEIS complex or syndrome is the most severe form of the exstrophy-epispadias complex and is characterized by the existence of an omphalocele, bladder exstrophy, anal imperforation and spina bifida. We report an atypical case of OEIS complex associated with further birth defects admitted to our department. The diagnostic and therapeutic approach to the complex congenital malformations involved are highlighted, as well as difficulties encountered in a limited resource setting. Case Report: This was a neonate referred for the management of a congenital malformation on the first day of life. The baby was born vaginally at 35 weeks of gestation with a birth weight of 2000 g and significant major risk factors for neonatal sepsis. Two antenatal ultrasounds had revealed fetal uropathy. On admission, the clinical exam revealed: a type 1 omphalocele, an anorectal malformation with a recto-urinary fistula and a covered lumbosacral dysraphism. Paraclinical examinations revealed an associated cardiac anomaly. The karyotype analysis was not done due to lack of financial means. Supportive care was given and the neonate underwent surgical reconstruction of birth defects on day 20. Conclusion: The OEIS complex is a rare morbid congenital polymalformative syndrome in neonates. Patients require keen diagnostic enquiry and immediate postnatal multidisciplinary management, with long-term follow-up.

Resumen

Medical ultrasound is a particularly useful imaging method used in the diagnosis of urinary fetal anomalies. One such fetal anomaly is the posterior urethral valve (PUV), which is a congenital malformation of the male urethra occurring early in gestation life. PUV is a common cause of obstructive uropathy in males and fetal death during pregnancy. We report from a medical imaging perspective on a rare and high-risk case of a PUV detected during routine antenatal ultrasound imaging in Botswana. The first scan performed at 16 weeks of gestation age was unremarkable. However, subsequent antenatal ultrasound scans at and after 20 weeks demonstrated bilateral hydronephrosis, distended ureters, and a urinary bladder which gradually increased with the gestation age. There was also a corresponding reduction in amniotic fluid and fetal movements. As a result of these complications, the pregnancy was classified as a “high-risk.” At 30 weeks, spontaneous labour occurred, and a fresh still birth male fetus was delivered.

Resumen

Normal kidney and urinary tract development is a complex process, regulated by a strict space-time-corrected sequential activation of a cascade of genes encoding transcription factors, growth factors, cell death/proliferation factors and adhesion molecules. An alteration disrupting this sequential gene expression may cause a defective ureteric bud-to-metanephric mesenchyme cross-talk that results in a renal and urinary tract developmental abnormality (congenital anomalies of kidney and urinary tract - CAKUT). Phenotype severity depends on the stage of nephrogenesis in which the alteration of the developmental program occurs, thus renal dysplasia is the most severe manifestation. However, little is known about CAKUT pathogenesis. The recent advent of microarray technology provided an unique tool to identify genes potentially involved in the pathogenesis of several diseases. During the first stage of this research, we applied the microarray technique to study gene expression profiles of primary renal cell cultures, using an array composed by 21329 oligonucleotides. The aim was to identify potential biomarkers of renal dysplasia. Four genes seemed to be more interesting (UPK1B, SOX11, SPRY1, MMP2). We analysed the expression of these four genes using Real Time PCR on RNA extracted from renal tissue samples of 10 patients with a histological picture of renal dysplasia and 10 with histologically normal renal tissue. Mutation analysis of SPRY1 gene, whose murine homologue is hugely involved in the regulation of GDNF growth factor's expression during ureteric branching, was carried out on 27 patients with renal duplicity. Mutation analysis identified 2 new genomic variants - whose frequency was analysed in a control population - that may be "genomic variants involved in splicing" (SpaGVs). Our research results allow to hypothesize that SPRY1 gene may be involved in the pathogenesis of kidney and urinary tract developmental diseases.
