Summary
Urrets-Zavalia syndrome (UZS), characterized by a persistently dilated pupil after eye surgery, can be effectively managed with surgical pupilloplasty. This procedure resolves UZS and prevents secondary glaucoma by repositioning the iris.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Ocular Anatomy
Background:
- Unexplained pupil dilation is a recognized complication after intra-ocular surgery.
- Urrets-Zavalia syndrome (UZS) lacks a standardized treatment protocol.
- Surgical pupilloplasty has been previously explored for UZS management.
Purpose of the Study:
- To elucidate the development of Urrets-Zavalia syndrome (UZS) post-operatively.
- To highlight the non-responsiveness of the dilated pupil to miotics.
- To present surgical pupilloplasty as a viable treatment for UZS.
Main Methods:
- Surgical pupilloplasty to reposition iris tissue.
- Intra-operative gonioscopy to assess anterior chamber angle.
- Anterior segment optical coherence tomography for structural analysis.
Main Results:
- Surgical pupilloplasty effectively centralizes the iris.
- The procedure alleviates mechanical blockage of the anterior chamber angle.
- Peripheral anterior synechias are often released, resolving pupillary block.
Conclusions:
- Surgical pupilloplasty is a successful treatment for Urrets-Zavalia syndrome.
- Timely intervention prevents secondary glaucoma by addressing iris-angle apposition.
- This technique restores normal pupillary function and protects ocular structures.

01:22Ureters
695
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...

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

33
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
