Duplicated or Ectopic Renal Collecting System in Two Adult Emergency Department Patients

Duplicated renal collecting system is a urological anomaly often found in pediatric patients. It is less commonly diagnosed in adulthood, particularly in a pregnant patient. Many point-of-care ultrasonography users may not be aware of this diagnosis, particularly in patients in the emergency department. It is important to recognize the duplicated system because in general, patients will often have hydronephrosis in only one renal pole rather than the entire kidney, which corresponds to an unequal renal function as documented on renal nuclear medicine functional scans.

Rationale: Rupture of an unscarred uterus after in vitro fertilization–embryo transfer (IVF-ET) in a primiparous woman is rare. Assisted reproductive technology (ART)-induced rupture of an unscarred uterus is usually attributable to increased dizygotic twinning rates. Salpingectomy can result in cornual scarring and increase the risk of uterine rupture as well as the mortality rate in a subsequent ectopic pregnancy. Here, we present the first reported case of a spontaneous, third-trimester, uterine rupture in a primiparous woman after IVF-ET due to a history of bilateral salpingectomy because of bilateral oviduct a...

CONCLUSION: In this study, a relationship between maternal BMI, VAS thickness, SAT thickness, the estimated fetal weight, birth weight, and renal pelvicalyceal dilatation have been shown. Increasing maternal adipose tissue may have a protective effect of mechanical pressure of growing uterus on the ureters. PMID: 31478185 [PubMed - as supplied by publisher]

Abstract OBJECTIVE: To examine the performance of the routine 11-13 weeks scan in detecting fetal non-chromosomal abnormalities. METHODS: This was a retrospective study of prospectively collected data from 100,997 singleton pregnancies attending for a routine ultrasound examination for fetal anatomy, according to a standardized protocol, at 11-13 weeks' gestation. All continuing pregnancies had an additional scan at 18-24 weeks and 71,754 had a scan at either 30-34 or 35-37 weeks. The final diagnosis of fetal abnormalities was based on the results of postnatal examination in the case of livebirths and on the ...

We present the clinical course of a 10 years old child with diagnosis of Prune-Belly syndrome. A urinary tract abnormality was suspected starting 25 weeks of gestation, when a routine ultrasound showed oligohydramnios, increased size urinary bladder, bilateral hydronephrosis and megaureters, thin abdominal wall. Diagnosis: Prenatal suspicion of Prune-Belly syndrome plays a deciding role in renal disease progression. A detailed clinical exam at birth established the diagnosis of Prune-Belly syndrome. Renal ultrasound confirmed bilateral grade III hydronephrosis and megaureters, with empty bladder, suggesting an obstructi...

Authors: Ma Z, Lu D, Zhao W, Wang H Abstract Expression levels of retinol-binding protein (RBP) and albumin (Alb) in the kidney of patients with neonatal hydronephrosis were detected to explore whether RBP and Alb can be used as diagnostic indicators for neonatal hydronephrosis. Blood and urine samples from neonates with hydronephrosis in the obstetrics and gynaecology department of Hongqi Hospital Affiliated to Mudanjiang Medical University from January 2016 to January 2018, and healthy newborns were collected. RBP and Alb levels in neonates, and the expression of IL-12 in serum of the mothers were detected by ELI...

Abstract PURPOSE: To evaluate the effect of JJ stents on SWL treatment of moderate (15-25mm) renal pelvic stones. MATERIALS AND METHODS: Between January 2016 and December 2017, a total of 152 adult patients who were planned to undergo SWL for a single radiopaque renal pelvic stone were included in the study. Patients with solitary kidney, congenital abnormality, skeletal tract abnormalities, previous urinary system surgery, hydronephrosis (grade 2 or more), untreated urinary tract infection, bleeding disorder, and suspected pregnancy were excluded. The remaining 114 patients were randomly divided into two gro...

AbstractPurposeTo evaluate the predictive role of maternal urinary CA 19-9 as a non-invasive marker for diagnosing antenatal posterior urethral valve (PUV).MethodsA total of 40 women in the third pregnancy trimester were enrolled. Case group (group A) consisted of 20 women with a diagnosis of antenatal PUV. Twenty women with similar gestational age, fetal sex, normal US, and no history of congenital anomalies were chosen as a control group (group B). Maternal urine samples were collected and urinary CA 19-9 was measured in both groups. The correlations between maternal urinary CA 19-9 and APD (measured during pregnancy and...

Rationale: Intrauterine device (IUD) is commonly used in China. Its complications include uterine perforation, IUD ectopic migration, etc. However, a migrated IUD rarely leads to renal failure. Patient concerns: IUD insertion in the patient was followed by unexplained pain in the left renal area, without bladder irritation or dysuresia. Diagnoses: Hydronephrosis, renal failure, migrated IUD. Interventions: The patient underwent laparoscopic and retroperitoneoscopic left nephrectomy, partial ureterectomy, and migrated IUD extraction. Outcomes: No complications were found after 1 year of follow-up. Lesson: A...
