Megaureters are common in children but are rarely found in adults, probably due to the scarcity of clinical symptoms. Reconstruction surgery in adults has been performed only exceptionally up to a few years ago. We encountered 7 adults with 7 megaureters in the recent 6 years. The underlying pathologic entities responsible for the megaureters were non-peristaltic lower segment, ectopic ureter and ureterovesical junction stenosis. Six adults with 6 megaureters were treated by complete surgical reconstruction and reimplantation of the ureter. The outcome of all the reported cases was excellent.

Article Synopsis
- The study assesses the long-term outcomes of endoscopic management techniques for primary obstructive megaureter (POM) in adults, involving 76 patients treated from September 2015 to January 2024.
- Using endoscopic dilation and additional incision methods, the procedures showed a high success rate of 92.1% over an average follow-up of 42 months, with no intraoperative complications.
- The findings suggest that this endoscopic approach is a safe and effective first-line treatment for adult POM, potentially improving patient outcomes significantly.

Objective: Megaureter (MU) is an uncommon condition in adults. The aim is to present a review of the current literature.
Materials And Methods: A literature search was conducted to explore the current literature including case reports on MU in adults in the period 2003-2023.

Purpose: To summarize our experience in the management of congenital anomalies in the kidney and urinary tract (CAKUT) in adults.
Materials And Methods: We conducted a retrospective chart review of all adult patients who underwent primary surgical intervention for CAKUT between 1998 and 2021.
Results: The study included 102 patients with a median age of 25 (interquartile range, 23-36.
Article Synopsis
- A case of complete ureteral triplication, a rare urinary tract anomaly, was diagnosed in an adult male with pyelonephritis, showcasing its unusual presentation in adulthood.
- The patient underwent a right partial nephrectomy to remove a non-functional upper kidney segment while preserving a blind ureteral remnant, resulting in relief from flank pain and urinary infections.
- This case highlights the lack of established surgical methods for adult triplicated ureters but suggests partial nephrectomy can be an effective, less invasive treatment option.
Minimally invasive ureteral reimplantation or endoscopic management for primary obstructive megaureter: a narrative review of technical modifications and clinical outcomes.

Background And Objective: Primary obstructive megaureter (POM) has various courses in different age populations. Although open ureteral reimplantation (OUR) remains the standard treatment for symptomatic POM, it is highly invasive with potential complications. In recent years, minimally invasive ureteral reimplantation (MIUR), including laparoscopic ureteral reimplantation (LUR) and robotic-assisted laparoscopic ureteral reimplantation (RALUR), and endoscopic management, such as double-J stent insertion, endoureterotomy and endoscopic balloon dilatation (EBD), have been utilized for POM in selected patients.
