Variations and Asymmetry in Sacral Ventral Rami Contributions to the Bladder.
Diagnostics (Basel)
January 2025
Aging + Cardiovascular Discovery Center, Department of Biomedical Education and Data Science, Lewis Katz School of Medicine of Temple University, Philadelphia, PA 19140, USA.
We have demonstrated in human cadavers and canines that nerve transfer to bladder vesical nerve branches is technically feasible for bladder reinnervation after nerve injury. We further clarify here that sacral (S) ventral rami contribute to these vesical branches in 36 pelvic sides (in 22 human cadavers). Gross post-mortem visualization and open anterior abdominal approaches were used, as was micro-CT of sacral nerve bundles, for further confirmation when needed.

Article Synopsis
- The study assessed the feasibility and outcomes of I-LEVUR, a surgical technique for treating upper moiety ectopic ureter in patients with a duplex renal system, which avoids reimplanting the lower ureter.
- Twelve patients, mostly young children, underwent the procedure with a mean surgical time of 127.5 minutes, and no major complications were reported post-surgery.
- Results indicated improved urinary continence in all patients after an average follow-up of about 78.5 months, suggesting that I-LEVUR is a safe and effective option that preserves normal ureter function.
Extraperitoneal robotic approach to the uretero-vesical junction in children: Initial experience and a step-by-step video presentation.

Nantes Université, CHU Nantes, Department of Pediatric Urology, F-44000 Nantes, France. Electronic address:
Introduction & Objectives: The use of transperitoneal robotic-assisted procedures for ureterovesical junction (UVJ) anomalies in pediatric patients is increasing. However, the extra-peritoneal approach potentially less invasive, remains underexplored with robotic approach in pediatric patients. We present our experience of robot-assisted extra-vesical laparoscopic extra-peritoneal UVJ surgery.

J Pediatr Urol
December 2024
Department of Pediatric Surgery and Urology, Hôpital Necker-Enfants Malades, Assistance Publique-Hôpitaux de Paris, Paris, France; Université Paris Cité, Paris, France.
Article Synopsis
- A study was conducted to evaluate the effectiveness of a combined surgical technique for treating primary asymmetrical vesicoureteral reflux in children, comparing it to the standard method of bilateral cross-trigonal reimplantation.
- The research focused on surgical complications, post-operative urinary tract infections (fUTIs), and the need for further interventions over an 18-year period, involving 80 children who had experienced febrile UTIs.
- Results showed comparable success rates between the two surgical groups, but the combined technique had a significantly shorter hospital stay and reduced need for bladder catheters and ureteral stents.
Persistent ureteric stump syndrome post ureteric re-implantation following impacted distal ureterolithiasis: Experience from tertiary hospital. Case report.

Introduction And Importance: Ureteric stump syndrome [USS] is a series of febrile recurrent lower abdominal pain, urinary tract infections, and hematuria that sometimes present with empyema as a rare complication. The ureteric stump is left after ureteric re-implantation due to an impacted stone at the Vesical-ureteric junction [VUJ], or after nephrectomy of a non-functional kidney due to a distal stone; the ureteral stump forms a source of infection to the urinary bladder, in addition to long-term obstructive stones left at the ureteric stamp. This usually cause chronic irritation of the mucosa and potentially change to metaplasia, dysplasia and malignancy.
