Department of Obstetrics and Gynecology, Seoul Asan Medical Center, University of Ulsan College of Medicine, 88, Olympic-ro 43-gil, Songpa-gu, Seoul 05505, Korea.

The aim of this study was to present a new case of congenital Herlyn-Werner-Wunderlich syndrome, a rare anomaly of the female reproductive tract, and review the related literature. A 12-year-old girl presented with severe dysmenorrhea since menarche and magnetic resonance imaging showing a bicornuate uterus, double cervix, right hematometra, and hematosalpinx with ipsilateral renal agenesis, accompanied by a remnant distal ureter with hydroureter. A diagnostic cystoscopy and a reduced-port robot-assisted laparoscopy with chromopertubation were performed in order to identify the anomaly. Read More

Ureterocele as a cause of chronic intractable abdominal pain.

BMJ Case Rep 2021 Nov 11;14(11). Epub 2021 Nov 11.

Pain Management, Cleveland Clinic Foundation, Cleveland, Ohio, USA.

A ureterocele is a submucosal, cystic dilation of the terminal ureter, either congenital or acquired, as it enters the bladder. It is a rare clinical entity that can be entirely asymptomatic and present as an incidental finding or can manifest in the form of distressing symptoms such as unremitting abdominal pain, haematuria, obstructive uropathy, to name a few. The authors present a case of abdominal pain in a 43-year-old woman who was presumptively attributed to various clinical entities and was finally referred to the chronic pain clinic. Read More

Risk of urinary tract infection in patients with hydroureter: An analysis from the Society of Fetal Urology Prenatal Hydronephrosis Registry.

J Pediatr Urol 2021 Dec 21;17(6):775-781. Epub 2021 Sep 21.

CHOC Children's, Division of Pediatric Urology, Orange, CA, USA; University of California, Irvine, Department of Urology, Irvine, CA, USA.

Background: Prenatal hydronephrosis is one of the most common anomalies detected on prenatal ultrasonography. Patients with prenatal hydronephrosis and ureteral dilation are at increased risk of urinary tract infection (UTI) and continuous antibiotic prophylaxis (CAP) is recommended. However, current guidelines do not define the minimum ureteral diameter that would be considered a dilated ureter in these patients. Read More

[Ectopic Ureterocele of Adult Male with Urination Difficulty : A Case Report].

Hinyokika Kiyo 2021 Aug;67(8):381-384

The Department of Urology, Hyogo Prefectural Nishinomiya Hospital.

Ectopic ureteroceles is sometimes noted in children as an incidental finding in antenatal ultrasonography results or because of symptoms related to a urinary tract infection. In contrast, it is rarely noted in adults, with only 18 cases in Japan presented in literature. We report here a 30-year-old adult male with an ectopic ureterocele discovered due to urination difficulty. Read More

Fetal Urinoma Due to Circulatory Disorders in an Umbilical Artery: Case Report.

Pediatr Dev Pathol 2021 Jul-Aug;24(4):383-387. Epub 2021 Mar 22.

Sackler School of Medicine, Tel Aviv University, Tel-Aviv, Israel.

Fetal urinoma is defined as an encapsulated accumulation of extravasated urine within the perirenal space or retroperitoneum. It is an uncommon finding in prenatal practice, and the vast majority of known cases are strongly associated with the existence of a urinary obstruction, such as posterior urethral valves, ureteropelvic junction obstruction, or ureterocele. We report a unique case of prenatally detected fetal bladder urinoma that occurred in the absence of an apparent obstructive uropathy, but was associated with extensive ischemic necrosis and calcifications of adjacent bladder wall, coexistent with signs of vascular supply decompensation.

Assessment of distal ureteral and ureterovesical junction visualization on contrast-enhanced voiding urosonography.

Pediatr Radiol 2021 Jul 12;51(8):1406-1411. Epub 2021 Feb 12.

Department of Medical Imaging, Ann & Robert Lurie Children's Hospital, 225 E. Chicago Ave., Chicago, IL, 60611, USA.

Background: Contrast-enhanced voiding urosonography (CEVUS) uses intravesically administered microbubble contrast to detect vesicoureteral reflux (VUR) and urethral anomalies with ultrasound. Multiple studies have suggested CEVUS can replace voiding cystourethrogram (VCUG) as a radiation-free alternative. Analysis of the ureterovesical junction and ureters on VCUG documenting the ureterovesical junction position, ureteral duplication, periureteral diverticula and ureteroceles is important as anatomical variations may affect management and surgical approach.

Congenital Anomalies of the Upper Urinary Tract: A Comprehensive Review.

Radiographics 2021 Mar-Apr;41(2):462-486. Epub 2021 Jan 29.

From the Department of Radiology, Diagnósticos da América SA (DASA), Av Juruá 434, Alphaville Industrial, Barueri, SP 06455-010, Brazil.

The upper urinary tract is the most common human system affected by congenital anomalies. Congenital anomalies of the kidneys and ureters comprise a wide spectrum of disorders ranging from simple variants with no clinical significance to complex anomalies that may lead to severe complications and end-stage renal disease. They may be classified as anomalies of renal form, which are subclassified as structural anomalies (eg, persistent fetal lobulation, hypertrophied column of Bertin, and dromedary hump) and fusion anomalies (eg, horseshoe kidney and pancake kidney); anomalies of renal position (eg, renal malrotation, simple renal ectopia, and crossed renal ectopia) and renal number (eg, renal agenesis and supernumerary kidney); and abnormalities in development of the urinary collecting system (eg, pyelocaliceal diverticulum, megacalycosis, ureteropelvic junction obstruction, duplex collecting system, megaureter, ectopic ureter, and ureterocele).

Diagnostic clues, pitfalls, and imaging characteristics of '-celes' that arise in abdominal and pelvic structures.

Abdom Radiol (NY) 2020 11;45(11):3638-3652

Department of Internal Medicine, Pratumthani Hospital, 7 Ladlumkaew Muang District, Pratumtani, 12000, Thailand.

'-Celes' is an ancient Greek language suffix that means 'tumor,' 'hernia,' 'swelling,' or 'cavity.' There are many '-celes' in the abdomen and pelvis that may be encountered during routine imaging interpretation, including santorinicele, choledochocele, ureterocele, lymphocele, mucocele, rectocele, cystocele, peritoneocele, varicocele, spermatocele, hydrocele, hematocele, pyocele and syringocele. Most '-celes' are detected incidentally at imaging for other clinical indications, but some deserve more attention due to a range of clinical symptoms or functional disorder that can adversely affect patient quality of life.
