Summary
A novel less-traumatic needle for kidney puncture significantly reduced hemoglobin drop in patients undergoing percutaneous nephrolithotomy (PCNL). This innovation may also prevent severe complications without affecting the stone-free rate.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Nephrolithotomy
Background:
- A novel MG needle was developed to decrease complication rates during kidney puncture.
- The needle features a pointed cannula, an atraumatic mandrin-bulb, and a spring mechanism.
Purpose of the Study:
- To assess the efficacy and safety of a novel, less-traumatic MG needle for kidney puncture during percutaneous nephrolithotomy (PCNL).
- To compare the outcomes of using the MG needle versus standard needles in a clinical trial.
Main Methods:
- A prospective, randomized, single-center study was conducted.
- The experimental group used the novel MG needle for kidney puncture.
- The control group used standard Trocar or Chiba needles.
Main Results:
- Sixty-seven patients were enrolled in the study.
- Patients receiving standard puncture (n=33) experienced a significantly higher hemoglobin drop (p=0.024).
- While overall complication rates were similar (p=0.351), two severe Clavien-Dindo IIIa complications (urinoma) occurred in the control group.
Conclusions:
- The less-traumatic MG needle may reduce hemoglobin drop and prevent severe complications during PCNL.
- The stone-free rate (SFR) in PCNL remains unaffected by the type of needle used for renal access.

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

81
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

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...

29
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
