Purpose: We have retrospectively evaluated all patients who underwent endoscopic puncture (EP) of ureterocele over the last 26 years with special reference to the need in the second intervention and disease-free status.
Methods: 78 (69%) of the 112 patients following EP and completed follow-up were included. 51 (65%) were diagnosed prenatally and 27 (35%) postnatally. 46 patients (60%) had intravesical, while 32 (40%) had ectopic ureterocele. Median age at time of puncture was 4 months. Median time of the follow-up was 12 years (range 1-26 years), while 23 (30%) followed over 10 years and 15 (19%) completed adolescent period.
Results: Four children with ectopic ureterocele required secondary puncture. Ectopic ureterocele children had significantly more postoperative UTIs (13 (40%) ectopic vs 4 (19%) intravesical p = 0.047). 19 RRUs (44%) showed spontaneous resolution of VUR. 14 (18%) children required additional surgery: 7, endoscopic correction of VUR; 3, ureteral reimplantation and 4, partial nephrectomy. The need for additional surgery following puncture was higher in the group of children with ectopic ureterocele; however, this difference did not reach a statistical significance (p = 0.716).
Conclusions: Our data show that EP of ureterocele is a durable and long-term effective procedure in vast majority of the children.

: An interlabial mass in newborn girls is diagnosed usually after birth or during the first days or weeks of life. According to various studies, its prevalence ranges between 1 : 500 and 1 : 7,000 newborn girls. A mass in the vaginal introitus or between the labia majora can cause a diagnostic dilemma and may be suspected even of ambiguous genitalia.

Article Synopsis
- Ectopic ureteroceles are rare in adults but often found in children, typically discovered during pregnancy ultrasounds or through UTI symptoms.
- A 24-year-old woman faced recurrent UTIs and severe urinary retention due to a large ectopic ureterocele, confirmed through imaging and cystoscopy.
- The minimally invasive treatment led to her full recovery and emphasizes the need to consider ectopic ureteroceles in adult women with frequent urinary issues.
Sonographic Differentiation From Pseudoureterocele of Ectopic Ureter and Ureterocele in Pediatric Patients.
J Ultrasound Med
January 2025
Department of Radiology, Saitama Children's Medical Center, Saitama, Japan.
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
- The study aimed to evaluate the effectiveness of endoscopic treatments for ureteroceles, focusing on how the location (intravesical vs. ectopic) and anatomy (single vs. duplicated systems) impact treatment success.
- Researchers systematically reviewed multiple medical databases, analyzing 83 studies with a total of 3022 patients, to compare surgical outcomes based on these factors.
- The findings revealed that patients with ectopic ureteroceles and those with duplex systems had significantly higher rates of reoperation after endoscopic procedures, indicating a need for careful consideration in treatment planning.
