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 VII: Vascular Imaging

Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

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.

Imaging Studies III: Computed Tomography

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Summary

Fluoroscopic screening time (FST) during percutaneous nephrolithotomy (PNL) increases with larger stone burden and multiple access procedures. Surgeon experience is key to minimizing radiation exposure in these complex cases.

Area of Science:

Urology
Medical Imaging
Nephrology

Background:

Percutaneous nephrolithotomy (PNL) is a standard urological procedure.
Fluoroscopic guidance is routinely used during PNL.
Minimizing radiation exposure is a key consideration in PNL.

Purpose of the Study:

To retrospectively evaluate factors influencing fluoroscopic screening time (FST) during PNL.
To identify patient and procedural variables associated with prolonged FST.

Main Methods:

Retrospective analysis of 282 patients undergoing PNL by a single surgeon.
Data collected included patient demographics, stone characteristics, and procedural details.
Statistical analysis correlated FST with factors like BMI, stone burden, and number of accesses.

Main Results:

Mean FST was 10.19 minutes.
Increased stone burden and multiple access procedures significantly prolonged FST (p=0.001 and p=0.007, respectively).
BMI, stone configuration, hydronephrosis, prior open surgery, and access location did not significantly impact FST.

Conclusions:

Fluoroscopic screening time in PNL is primarily influenced by stone burden and the need for multiple accesses.
Complex cases requiring multiple accesses and larger stones necessitate management by experienced surgeons to reduce radiation exposure.
Factors such as BMI and access location did not demonstrate a significant effect on FST in this study.
