Ureters

Ureters

The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

Summary

Urethral stricture treatments have evolved significantly. Urethroplasty, using techniques like Excision and Primary Anastomosis (EPA) or buccal grafts, is now the gold standard for managing urethral strictures.

Area of Science:

Urology
Surgical History

Background:

Urethral strictures represent one of the oldest documented urological conditions.
Historical treatments, primarily dilatation, offered limited success and were largely palliative.

Purpose of the Study:

To review the historical evolution of urethral stricture management.
To examine current trends and guidelines in urethral stricture treatment.

Main Methods:

A comprehensive literature review was performed using PubMed.
The review focused on the history of urethral strictures and contemporary management guidelines.

Main Results:

Early treatments for urethral strictures, such as dilatation, were found to be disappointing.
Reconstructive urology has advanced treatment, with Excision and Primary Anastomosis (EPA) and one-stage augmentation urethroplasty with buccal grafts being key advancements.

Conclusions:

Urethroplasty is recognized as the definitive treatment for urethral strictures.
Current research focuses on refining urethroplasty techniques to minimize patient morbidity.
