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...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...

Summary

Monoplanar percutaneous renal access for percutaneous nephrolithotomy (PNL) is safe and effective. This technique offers reduced puncture time and high stone-free rates, making it a viable alternative for kidney stone treatment.

Surgical Techniques
Nephrolithotomy

Background:

Percutaneous renal access is critical for percutaneous nephrolithotomy (PNL) success.
The adequacy of access impacts procedure success and complication rates.
Monoplanar access, using only vertical plane fluoroscopic projections, differs from biplanar methods.

Purpose of the Study:

To evaluate the operative outcomes of the monoplanar access technique in PNL.
To assess the safety and efficacy of monoplanar PNL.

Main Methods:

A retrospective study of 200 patients undergoing monoplanar PNL for renal stones.
Data collected included patient demographics, procedure details, and perioperative/postoperative outcomes.
The same surgical team performed all procedures from October 2009 to December 2011.

Main Results:

Mean operation time was 79.8 minutes, and mean puncture time was 0.83 minutes.
The stone-free rate on postoperative day 1 was 80.5%.
The final success rate, including additional treatments, reached 98% by the third month, with only one severe complication (colon injury).

Conclusions:

Monoplanar access is a safe and effective technique for PNL.
Reduced puncture time is a significant advantage of this method.
This technique contributes to high success rates in treating renal stones.
