Urinary Tract Calculi VI: Surgical Management

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Summary

This summary is machine-generated.

Intraoperative 5-fluorouracil (5-FU) under the conjunctival flap during glaucoma surgery (trabeculectomy) is safe and effective. This method achieved an 85.4% success rate, reducing intraocular pressure and medication needs.

Area of Science:

Ophthalmology
Surgical Innovation
Glaucoma Management

Background:

Trabeculectomy is a common glaucoma surgery.
Managing intraocular pressure (IOP) is crucial for preventing vision loss.
Optimizing surgical techniques to improve trabeculectomy outcomes is an ongoing area of research.

Purpose of the Study:

To evaluate the safety and efficacy of intraoperative 5-fluorouracil (5-FU) applied beneath the conjunctival flap during trabeculectomy.
To assess the success rate and impact on IOP and medication use in glaucoma patients.

Main Methods:

Prospective case series of 43 consecutive glaucoma patients.
Trabeculectomy performed with intraoperative topical 5-FU administration.
Outcomes assessed at 6-month follow-up, defining success as IOP ≤21 mm Hg with ≥20% drop and minimal visual acuity loss.

Main Results:

Overall success rate was 85.4%.
Mean IOP decreased from 31.4 to 15.1 mm Hg; mean medication use dropped from 2.8 to 0.4.
Success rates were 69.2% in high-risk and 92.9% in low-risk eyes. No corneal complications occurred.

Conclusions:

Intraoperative 5-FU application directly to the trabeculectomy site is a safe and effective glaucoma surgery method.
It offers a valuable alternative for glaucoma treatment, though success may be lower in high-risk patients.
The technique demonstrates significant IOP reduction and decreased reliance on glaucoma medications.
