Introduction And Importance: Ectopic ureteroceles are primarily found in children, often detected incidentally during antenatal ultrasonography or due to urinary tract infection (UTI) symptoms. However, they are rare in adults, with limited published cases.

Case Presentation: This report details a case of a 24-year-old woman who experienced recurrent UTIs and sudden urinary retention, ultimately needing manual compression to urinate due to poor urine flow.

Article Synopsis
  • This study investigates how to differentiate between pseudoureterocele and ureterocele using ultrasound imaging in patients with duplex collecting systems exhibiting intravesical cystic lesions.
  • Nineteen patients were analyzed, and the researchers compared ultrasound findings like the presence of a muscular layer and a "notch sign" in these lesions.
  • Significant differences were found in the characteristics of the lesions, aiding in accurate diagnosis and treatment planning for ectopic ureters and ureteroceles in children.

Article Synopsis
  • The study reviews the outcomes of open distal ureteroureterostomy (UU) surgery for children with duplicated collecting systems and no lower pole vesicoureteral reflux (VUR), conducted across multiple centers from 2009 to 2022.
  • A total of 127 patients were analyzed, predominantly females, with most undergoing surgery due to prenatal hydronephrosis and a mean age of 18 months at operation.
  • Post-operative results showed a low complication rate, with the mean operative time being 86 minutes and an average hospital stay of 1.1 days; only a small percentage experienced minor complications.

Article Synopsis
  • Duplex kidney is a urinary tract anomaly linked to various structural abnormalities, and this study examines the imaging results of 21 children who underwent surgery for it.
  • The imaging techniques, ultrasound (US) and MRI, were compared to histopathology, revealing that dysplastic changes were common, especially in cases of obstructive nephropathy.
  • Key findings show that US and MRI effectively identify kidney issues, with loss of corticomedullary differentiation and specific MRI signals correlating with kidney fibrosis and function.

Article Synopsis
  • - This study evaluated how voiding cystourethrography (VCUG) affects outcomes for patients with duplex system ureterocele (DSU) who underwent endoscopic decompression (ED), involving 75 patients divided into three groups based on their VCUG results.
  • - The results indicated that patients with preoperative vesicoureteral reflux (VUR) had a significantly higher secondary surgery (SS) rate (82%) compared to those without VUR (32%) and those who didn't have a VCUG (25%).
  • - The findings suggest that while patients without VUR and those without a VCUG had similar outcomes, ongoing monitoring through VCUG could be useful for symptomatic patients after ED, and pre

Article Synopsis
  • The study focuses on evaluating children suspected of having a retrocaval ureter (RCU) during treatment for hydronephrosis, given that such cases are rarely diagnosed and can be easily missed.
  • A total of 13 patients were analyzed, with final diagnoses revealing 4 cases of RCU, 7 cases of ureteropelvic junction obstruction (UPJO), and 2 of duplicated collecting system.
  • Utilizing imaging techniques like ultrasonography, particularly with a stent in place, is crucial for confirming or ruling out RCU, and laparoscopic surgery can also help visually clarify the condition if needed.

Article Synopsis
  • * It provides valuable insights for urologists and emergency care practitioners on the diverse manifestations and treatment options for similar cases.
  • * Recent findings suggest that a modified reconstructive strategy may be effective for specific anatomical challenges, while many patients with duplex systems experiencing obstruction and infection typically require surgical intervention.

Congenital renal anomalies are common imaging findings and can often be detected antenatally. In some cases, these anomalies may go undetected and present in adulthood. We report a very rare case of unilateral renal agenesis in a 22-year-old male associated with an ipsilateral dilated blind-ended ureter that ectopically inserted into the seminal vesicle.

Purpose: Ureterocele has been hypothesized to be the risk factor for febrile urinary tract infections (F-UTIs) in patients with duplex collecting systems, but this has not been proved, and our goal was to assess the relation between ureterocele with duplex collecting systems and F-UTIs.

Methods: We included individual-participant data from patients seen for complicated duplex collecting systems from 2010 to 2020 retrospectively followed. Those with using continuous low-dose antibiotic prophylaxis and incompletely duplicated systems were removed from the study.

Various hydronephrotic, dysplastic or clinical pathologies can accompany ureterocele, which is a cystic dilatation of the intravesical part of the submucosal ureter. However, the development of cancer in the ureterocele is highly unusual. Hematuria is the most common sign, although imaging can also indicate alterations in the wall of the ureterocele.

  • Duplex renal collecting systems are common congenital urinary tract anomalies, often asymptomatic and detected incidentally; this study aims to analyze demographic and clinical characteristics of affected patients at a specific hospital over 11 years.
  • The study included 239 patients, with most (81.1%) over 24 months old; urinary tract infections were the most common symptom in 35.6% of cases, while 2% were asymptomatic and found during routine screenings, with associated anomalies like antenatal hydronephrosis also noted.
  • Surgical interventions varied based on symptoms and associated pathologies, including ureterocele excision, laparoscopic heminephrectomy, and ureteroneocystostomy, highlighting the importance of comprehensive

Article Synopsis
  • - Bladder leiomyomas are rare benign tumors, accounting for less than 0.5% of all bladder tumors, with roughly 250 cases documented globally, mostly occurring in middle-aged females.
  • - Symptoms often include obstructive urinary issues, and the initial diagnostic method of choice is an ultrasound, leading to a definitive diagnosis through histopathological examination.
  • - A case involving a 34-year-old male presented with dysuria and incomplete voiding; ultrasound identified a cystic mass, which was surgically removed, confirming the diagnosis of a bladder leiomyoma.

Sonographic differential diagnosis of duplex kidneys.

Pediatric Clinic, University of Erlangen/Nuremberg, Erlangen, Germany.

Duplex kidneys have two renal pelvises and two ureters, which can join on the way to the urinary bladder but can also enter the bladder separately. A distinction must be made between normal and pathological duplex kidneys. In normal duplex kidneys, both renal pelvises are normal in width, and the upper and lower poles are approximately the same size.

Introduction: Obstructive ureterocele is an intravesical cystic dilation of the distal end of the ureter associated with anhidramnios and dilation of both renal pelvises.

Methods: This is a case-series of prenatally diagnosed ureterocele. Cases were selected at a third level reference hospital in Monterrey Mexico between 2010 and 2018.
