Kidney Malformations

Congenital anomalies of the kidney and urinary tract (CAKUT) include isolated kidney malformations and urinary tract malformations. They have also been reported in Prune-Belly syndrome (PBS) and associated genetic syndromes, mainly 13, 18 and 21 trisomy. The AA focuses on bladder and urethral malformations, evaluating the structural and histological differences between two different cases of megacystis. Both bladders were examined by routine prenatal ultrasound screening and immunohistochemistry, comparing the different expression of smooth muscular actin (SMA), S100 protein and WT1c in megacystis and bladders of normal control from fetuses of XXI gestational age. Considering the relationship between the enteric nervous system and urinary tract development, the AA evaluated S100 and WT1c expression both in bladder and bowel muscular layers. Both markers were not expressed in the bladder and bowel of PBS associated with anencephaly. In conclusion, megacystis could be considered only a macroscopic definition, concerning the size of the fetal bladder rather than the embryologic origin; it may be a single or multiple malformation; the possible association with the bowel and/or encephalic malformations will decide the outcome and prognosis in fetal megacystis.

ABSTRACT Prune belly syndrome (PBS) is a rare congenital malformation of unknown etiology characterized by a triad of deficient abdominal wall musculature, undescended testicles and urinary tract malformations. Most of the patients have pulmonary, cardiac, skeletal and gastrointestinal tract anomalies. Lack of abdominal muscles leads to constipation due to inability to perform Valsalva maneuver, which helps push the stool out of the rectum during the defecation. Additionally, frequent respiratory tract infections, persisting constipation and urinary tract infections lead to the development of malnutrition in children. We report this case to raise the awareness of low socioeconomic and low-resource medical settings that malnutrition could be existed or caused by PBS. We also encourage the expansion of pediatric surgery and family medicine training to increase the number of specialist (family medicine) to report and refer PBS in earlier phase, while working in rural areas and remote provinces.

Current Paradigm

The current paradigm of urinary tract infection (UTI) pathogenesis takes into account the contamination of the periurethral space by specific uropathogens residing in the gut, which is followed by urethral colonization and pathogen ascension to the urinary bladder. Consequently, studying the relationship between gut microbiota and the subsequent development of bacteriuria and UTI represents an important field of research. However, the well-established diagnostic and therapeutic paradigm for urinary tract infections (UTIs) has come into question with the discovery of a multifaceted, symbiotic microbiome in the healthy urogenital tract. More specifically, emerging data suggest that vaginal dysbiosis may result in Escherichia coli colonization and prompt recurrent UTIs, while urinary microbiome perturbations may precede the development of UTIs and other pathologic conditions of the urinary system. The question is whether these findings can be exploited for risk reduction and treatment purposes. This review aimed to appraise the three aforementioned specific microbiomes regarding their potential influence on UTI development by focusing on the recent studies in the field and assessing the potential linkages between these different niches, as well as evaluating the state of translational research for novel therapeutic and preventative approaches.
