Drugs and Biologics

Drugs and Important Biological Agents (IBA) related to Pyelectasis:

1.	Pregnancy-Associated Plasma Protein-A (PAPP-A)IBA 10/01/2007 - "In particular, it enables to make: a first trimester screening combining it with nuchal translucency, and biochemical parameters of free beta-hCG and PAPP-A; a second trimester screening by the evaluation of up to 6 biometric parameters (biparietal diameter, cranial circumferentia, femur, humerus, pyelectasis and plica nucalis), and up to 7 associated morphologic parameters (hyperechogenic bowel, cardiac foci, interventricular defect, pericardial effusion, tricuspid valve regurgitation, right/left heart disproportion, and structural abnormalities). " 06/01/2007 - "In this simulation study, published statistical parameters for first-trimester free beta-human chorionic gonadotropin, pregnancy-associated plasma protein-A and nuchal translucency thickness, and second-trimester ultrasound markers (nuchal fold, hyperechoic bowel, short humerus, short femur, echogenic intracardiac focus, pyelectasis and major abnormality) were used to model the effectiveness of second-trimester genetic sonography combined with first-trimester screening. "
2.	DiureticsIBA 04/01/1985 - "[Radionephrography with diuretic stimulus in the study of pyelectasis]." 08/01/1998 - "Pyelectasis may be due to obstruction and this may be assessed by sonography during diuresis, urography or diuretic renography. "
3.	Propylthiouracil FDA Link 07/01/2023 - "Out of the three studies that used propylthiouracil, one baby underwent surgery for bilateral pyelectasis, vesicovaginal fistula, anal stenosis, and polydactyly. "
4.	Chorionic Gonadotropin (Human Chorionic Gonadotropin)FDA LinkGeneric 06/01/2007 - "In this simulation study, published statistical parameters for first-trimester free beta-human chorionic gonadotropin, pregnancy-associated plasma protein-A and nuchal translucency thickness, and second-trimester ultrasound markers (nuchal fold, hyperechoic bowel, short humerus, short femur, echogenic intracardiac focus, pyelectasis and major abnormality) were used to model the effectiveness of second-trimester genetic sonography combined with first-trimester screening. "
5.	cytidylyl-(3'-5')-cytidine (CpC)IBA 11/01/2006 - "We reviewed the presence or absence of sonographic markers for fetal abnormalities including nuchal thickening (NT), nasal bones (NB), extermities (HL, FL), umbilical cord diameter (UCD), bowel echogenity (BE), renal pyelectasis (DPR) and chorioid plexus cyst (CPC). " 08/01/2000 - "Non-cardiac markers were central nervous system malformations (CNS); choroid plexus cysts (CPC); abnormal nuchal skin fold (NSF); hyperechoic bowel (HB); and pyelectasis (PY). " 01/01/2021 - "Fetuses with any of soft markers including thickened nuchal fold (TNF), mild pyelectasis (MP), choroid plexus cyst (CPC), single umbilical artery (SUA), mega cisterna magna (MCM) and mild ventriculomegaly (MVM) were followed during pregnancy and birth. " 02/01/2009 - "Structural anomalies plus the following soft markers were assessed: nuchal fold thickening, choroid plexus cyst (CPC), echogenic intracardiac focus, echogenic bowel, renal pyelectasis, clenched hands; clinodactyly; short femur, short humerus and a single umbilical artery (SUA). "
6.	Biomarkers (Surrogate Marker)IBA 07/01/2009 - "The soft markers which are not significant as an isolated finding in young patients but are significant in combination with the biochemical markers, or in older age are: intracardiac echogenic focus, choroid pLexus cyst, pyelectasis and single umbilical artery. "
7.	PlasticsIBA 02/01/1956 - "Pyelectasis, secondary to ptosis, and ureteropelvic obstruction should be corrected by nephropexy or plastic repair. "
8.	Genetic Markers (Genetic Marker)IBA 09/01/2012 - "Rapid positive confirmation of mosaicism for a small supernumerary marker chromosome as r(8) by interphase fluorescence in situ hybridization, quantitative fluorescent polymerase chain reaction, and array comparative genomic hybridization on uncultured amniocytes in a pregnancy with fetal pyelectasis."
9.	Pentetic Acid (DTPA)FDA LinkGeneric 07/01/1997 - "During the course of a routine sonographic examination, we performed a detailed evaluation of the fetal genitourinary tract, Mild pyelectasis was defined as a pelvocalyceal fluid-filled space with the smallest of two transverse perpendicular sonographic measurements of > or = 4 mm and < 10 mm. Hydronephrosis was defined similarly, but with a measurement of > or = 10 mm. Postnatal urological assessment was obtained with routine renal ultrasonography, and voiding cystourethrography (VCUG), measurement of 99mTc-labelled diethylenetriamine pentaacetic acid (DPTA) mercaptacetyltriglycerine (MAG3), and intravenous pyelogram, as necessary. "
10.	alpha-Fetoproteins (alpha-Fetoprotein)IBA 05/01/1992 - "The predictive value of pyelectasis for Down syndrome (one in 90) compares favorably with other accepted indications for genetic amniocentesis, such as advanced maternal age and low maternal serum alpha-fetoprotein (MSAFP). "

Therapies and Procedures

1.	Antibiotic Prophylaxis 11/01/2000 - "Questions such as the definition of pyelectasis, whether these neonates should be selected for postnatal study in an attempt to prevent reflux nephropathy and urinary tract infections, which complementary investigations (postnatal ultrasonography, cystourethrography, isotopic studies) should be performed and when, and whether these neonates should be administered antibiotic prophylaxis are unresolved issues. "
2.	Therapeutics 12/01/2007 - "Congenital pyelectasis in children born from mothers on tenofovir containing therapy during pregnancy: report of two cases." 09/01/2002 - "However, the patient developed urolithiasis with resultant hematuria and pyelectasis during ACTH therapy. "
3.	Stents 06/01/2013 - "One dog that did not have a ureteral stent placed following the procedure developed short-term signs of renal pain and pyelectasis. "
4.	Prenatal Care (Care, Prenatal) 09/01/2002 - "All women 35 years of age or older registered for prenatal care between January 1990 and December 1998 were asked about their attitude towards genetic amniocentesis during the course of individual genetic counseling and once again after ultrasound examination inclusive of markers of aneuploidies (nuchal fold thickness greater than 6 mm, renal pyelectasis, choroid plexus cysts, and hyperechogenic bowel). "
5.	Cesarean Section (Caesarean Section) 10/25/2023 - "At 35 weeks, relapse of the megacystis was observed with bilateral pyelectasis and oligohydramnios, possibly due to healing of the bladder rupture, after which elective cesarean section was planned. "
