Abstract:

To gain insight into the role of transforming growth factor-beta 1 (TGF-beta 1) in the development of kidney pathology following fetal obstruction, we measured TGF-beta 1 gene expression, the active peptide, and the urinary concentration in a model of fetal bilateral urinary obstruction (BUO) in sheep. Fetal lambs underwent BUO at 60 (FO-60) or 80 days (FO-80) of gestation and were studied at 120 days. Independently of the onset or duration of obstruction, all fetuses developed type IV dysplasia (IV) associated with an arrest in the nephrogenesis or hydronephrosis. Fetal glomerular filtration rate was not significantly modified, whereas sodium tubular reabsorption was significantly decreased, and urinary TGF-beta 1 concentration was elevated in hydronephrosis but not in IV. Levels of TGF-beta 1 mRNA were increased in hydronephrosis compared with normal kidneys, and active TGF-beta 1 immunoreactivity was increased in both hydronephrotic and IV kidneys. In summary, TGF-beta 1 may play a role in the development of hydronephrosis and dysplasia in kidneys following fetal BUO. Its role in the arrest of nephrogenesis observed in the IV kidneys remains to be proved.

Abstract:

Purpose. We seek to correlate conventional hydronephrosis (HN) grade and hydronephrosis index (HI).Methods. We examined 1207 hydronephrotic kidneys by ultrasound. HN was classified by Society of Fetal Urology guidelines. HN was then gauged using HI, a reproducible, standardized, and dimensionless measurement of renal area. We then calculated average HI for each HN grade.Results. Comparing HI to standard SFU HN grade, average HI is 89.3 for grade I; average HI is 83.9 for grade II; average HI is 73.0 for grade III; average HI is 54.6 for SFU grade IV.Conclusions. HI correlates well with SFU HN grade. The HI serves as a quantitative measure of HN. HI can be used to track HN over time. Versus conventional grading, HI may be more sensitive in defining severe (grades III and IV) HN, and in indicating resolving, stable, or worsening HN, thus providing more information for clinical decision-making and HN management.

Abstract:

The objective was to determine the image quality of 3D diagnostic medical sonography (DMS) in children with hydronephrosis. 3D DMS was assessed based on 24 pediatric patients. Image quality was evaluated by two radiologists and a sonographer in terms of rib shadowing, cut-off parenchymal edges, motion artifact, and overall quality. The interreader reliability and relation between image quality and other variables were calculated. The results were based on images of 32 hydronephrotic kidneys. The average quality scoring of the images was quite high. Rib shadowing, cut-off edges, and motion artifact were present in the majority of the cases. The interreader reliability for overall quality, rib shadowing, cut-off, and motion was quite high. There was a correlation between the Society for Fetal and Neonatal Urology’s hydronephrosis grade and higher cut-off edges. Larger kidneys were more likely to show cut-off, motion, and lower quality scores. In this cohort of infants and toddlers with hydronephrotic kidneys, 3D DMS demonstrated good image quality; however, artifacts were attributed to kidney size and severity of hydronephrosis.

Abstract:

The majority of pregnant women in the U.S. undergo prenatal ultrasonography and approximately 0.5% of these examinations will detect fetal malformations. Up to one-half of these abnormalities include the genitourinary system and the most common urological finding is hydronephrosis. Some conditions associated with prenatal hydronephrosis portend a poor prognosis, while others can follow a fairly benign course. This review focuses on the definition and prenatal assessment of hydronephrosis, fetal intervention, and postnatal management.

Abstract:

With the increasing use of antenatal sonography, fetal hydronephrosis has been reported more frequently. Hydronephrosis is one of the most commonly identified prenatal anomalies, and the severity may vary from mild to severe, depending on the underlying cause. Many cases resolve spontaneously before birth, but for those that do not, the additional prenatal evaluation can identify cases sufficiently severe to require fetal intervention to preserve renal function. The benefits of these interventions must be balanced against the significant risks of the procedures and their sequelae in long-term efficacy. Evaluation before and after birth is warranted, and factors such as cause, severity, and whether the condition is uni- or bilateral are used to formulate decisions about additional assessment and potential intervention. Here we report a case of bilateral hydronephrosis which was detected during pregnancy. After delivery right side spontaneously resolves but there was worsening of left hydronephrosis in follow up and He undergoes a left pyeloplasty at 6 months of age and does well post operatively.J.

Abstract:

PURPOSE: Fetal hydronephrosis is a frequent finding due to advances in prenatal ultrasonography. The definition of fetal and neonatal urinary tract obstruction is a very difficult task requiring confirmation of reduced renal function and hydronephrosis. In this study we followed a series of consecutive patients with intrauterine hydronephrosis that persisted during post-natal life. METHODS: 116 newborns with antenatal hydronephrosis diagnosed by ultrasound and submitted to a specific post-natal evaluative protocol with a follow-up period of 6 years. RESULTS: In 45 (38.8%) of 116 patients, ureteropelvic junction (UPJ) obstruction was confirmed and surgical correction of the UPJ obstruction was done in 19 patients. From 26 children who were initially submitted to non-surgical treatment, only 6 (23%) needed a surgical approach during follow up. Overall analysis showed that surgery was performed in 25 patients with UPJ obstruction, and the others 20 patients were kept under clinical observation, since normal renal function was confirmed by scintigraphy scans. CONCLUSION: Fetal hydronephrosis due to UPJ obstruction deserves careful postnatal evaluation. UPJ obstruction is the most frequent anomaly and its surgical treatment has very precise indications. The evaluative protocol was useful in identify patients that could be followed-up with a non-surgical approach.

Abstract:

Purpose: The aim of this study is to determine the proportion of maternal hydronephrosis and symptomatic cases requiring treatment in pregnant women without ureteral stones and the characteristics of these cases. Materials and methods: Between February 2018 and April 2019, all pregnant women followed for pregnancy in obstetrics and outpatient policlinic were evaluated prospectively. Maternal hydronephrosis rate, degree of hydronephrosis and side, symptomatic hydronephrosis rate, maximum renal anteroposterior diameter of renal pelvis and visual analogue scale were detected. Symptomatic patients were treated conservatively or surgically. Findings in both treatment groups were analyzed by t-test or Chi-squared test. Pearson or Spermean’s tests were used for correlation analyzes. Results: A total of 1026 pregnant women aged 18-45 (27.7 ± 5.2 years) were followed prospectively. The rate of maternal hydronephrosis was 28.7% and the rate of symptomatic hydronephrosis was 4.7%. Of the patients with symptomatic hydronephrosis, 73.4% (3.5% of total) were treated conservatively and 26.5% (1.3% of total) were treated surgically. There was a positive correlation between hydronephrosis and gestational week (p < 0.001), visual analogue scale (p < 0.001) and hematuria (p < 0.05). There was a negative correlation between hydronephrosis and maternal age (p < 0.05) and number of pregnancies (p < 0,001). The anteroposterior diameter of renal pelvis (p < 0.001), visual analogue scale (p < 0.05) and fetal body weight values (p < 0.05) on the right side were higher in the surgical treatment group than the conservative group. Conclusions: The majority of cases with maternal hydronephrosis in pregnant women without ureteral stones are asymptomatic. Most symptomatic cases can also be treated conservatively. In cases requiring surgical treatment (1.3%), fetal body weight, visual analogue scale and anteroposterior renal pelvis diameter are higher.

Abstract:

Purpose. It was to quantify the intraobserver and interobserver variability of the sonographic measurements of renal pelvis and classify hydronephrosis severity.Methods. Two ultrasonographers evaluated 17 fetuses from 23 to 39 weeks of gestation. Renal pelvis APD were taken in 50 renal units. For intraobserver error, one of them performed three sequential measurements. The mean and standard deviation from the absolute and percentage differences between measurements were calculated. Bland-Altman plots were used to visually assess the relationship between the precision of repeated measurements. Hydronephrosis was classified as mild (5.0 to 9.9 mm), moderate (10.0 to 14.9 mm), or severe (≥15.0 mm). Interrater agreement were obtained using the Kappa index.Results. Absolute intraobserver variation in APD measurements was %. Interobserver variation of ultrasonographers was %. Neither intraobserver or interobserver error increased with increasing APD size. The overall percentage of agreement with the antenatal hydronephrosis diagnosis was 64%. Cohen's Kappa to hydronephrosis severity was 0.51 (95% CI, 0.33 to 0.69).Conclusion. Inter and intraobserver APD measurement errors were low in these group, but the agreement to hydronephrosis diagnosis and classification was fair. We suggest that standard and serial APD measurement can better define and evaluate fetal hydronephrosis.

Abstract Vesicoureteral reflux is characterized by the retrograde flow of urine from the bladder to the kidneys. Vesicoureteral reflux may be associated with urinary tract infection, hydronephrosis, and abnormal kidney development (renal dysplasia). Hydronephrosis - literally “water inside the kidney” - refers to distension and dilatation of the renal pelvis and calyces, usually caused by obstruction of the free flow of urine from the kidney. Untreated, it leads to progressive atrophy of the kidney. In cases of hydroureteronephrosis, there is distention of both the ureter and the renal pelvis and ureteres. However, in the current era, hydronephrosis that is evident on fetal ultrasonography often heralds a ureteral abnormality. Hydronephrosis is defined as dilatation of the renal pelvis and/or calyces. Vesicoureteral reflux may present before birth as prenatal hydronephrosis, an abnormal widening of the ureter or with a urinary tract infection or acute pyelonephritis. The authors present a case of bilateral VUR of IVth grade associated with congenital hydronephrosis of IIIrd grade, diagnosed before birth with bilateral hydronephrosis, and taken into evidence at 2 months when he was first diagnosed with urinary tract infection. Positive diagnosis was facilitated by laboratory investigations (urine analysis, urine culture, voiding cystourethrography, static renal scintigraphy).

Abstract:

Background: To assess the outcome of fetal hydronephrosis, based on antenatal sonography and to find the best cutoff APD of renal pelvis which lead to surgical outcome.Methods: All patients diagnosed with isolated fetal renal pelvic dilatation (RPD) were prospectively followed between January 2016 and December 2018. RPD was classified according to SFU grading into four grades and by APD classification to 3 groups. Group I (5-9.9 mm), group II (10-14.9 mm) and group III (≥15 mm).Results: Among a total of 57 patients, group I had 32 renal units, none required surgery; group II had 19 renal units, 5 (7.04%) required surgery; group III had 20 units, 11 (15.49%) required surgery. The difference in outcome between the groups was statistically significant (p=0.001). The causes of fetal hydronephrosis was transitional in 33.33%, pelvi ureteric junction obstruction in 33.33%, vesico ureteral reflux in 29.82%, and 3.5 % had posterior urethral valves. Of the 38 infants with RPD, urinary tract infection was seen in 36.84%. Thirty-four patients had MCUG of whom 29.82% had VUR. In 38 patients DTPA was performed with following results: 10.53% had partial obstruction and 14.04% showed complete obstruction.Conclusions: Fetal hydronephrosis less than 5mm runs a benign course. In APD greater than 15 mm and bilateral disease thorough postnatal evaluation and regular follow-up is necessitated for timely intervention. The best cutoff point of anteroposterior renal pelvis diameter that led to surgery was 15 mm, with sensitivity 91% and specificity 73.5%.
