Can extended upper pole ureterectomy prevent ureteral stump syndrome after proximal approach for duplex kidneys?

Int Braz J Urol 2021 Jul-Aug;47(4):821-826

Unidade de Urologia Pediátrica, Divisão de Urologia, Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo - FMUSP, SP, Brasil.

Introduction: Symptomatic duplex kidneys usually present with recurrent urinary tract infection due to ureteral obstruction (megaureter, ureterocele or ectopic ureter) and/or vesicoureteral reflux. Upper-pole nephrectomy is a widely accepted procedure to correct symptomatic duplex systems with poor functioning moieties, also known as upper or proximal approach. The distal ureteral stump syndrome (DUSS) can be a late complication of this approach. Read More

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

Pediatr Dev Pathol 2021 Mar 22:10935266211002730. 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.

Laser-puncture of the ureterocele in neonatal patients significantly decreases an incidence of de novo vesico-ureteral reflux than electrosurgical incision.

J Pediatr Urol 2021 Mar 3. Epub 2021 Mar 3.

Department of Pediatris, University Hospital of Split, Split, Croatia; Department of Pediatris, University of Split, School of Medicine, Split, Croatia.

Introduction: Endoscopic laser-puncture or electrosurgical incision are the most commonly used minimaly invasive approaches for the treatment of the ureterocele. Both techniques are mainly successful in decompressing of ureteroceles, but the consequence of such treatment may be formation of de novo vesicoureteral reflux and febrile urinary tract infection which could impact the final results.

Objective: To compare outcomes of treatment of two endoscopic techniques used in management of neonatal patients with intravesical ureterocele. Read More

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

Pediatr Radiol 2021 Feb 12. 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).
