percutaneous nephrolithotripsy

BACKGROUND: Percutaneous nephrolithotripsy (PCNL) is the main method for urinary calculi. An anesthesia method with little effect on the blood circulation and which does not affect the postoperative activity of a patient is lacking. OBJECTIVE: To compare the effects of paravertebral nerve block (PNB) and epidural block (EPB) on quadriceps femoris muscle (QFM) strength in patients after PCNL. METHODS: 163 patients were separated into two groups: EPB (81) and PNB (82)...

The recent development of mini-PCNL technique, allows tract formation with minimal damage to the renal parenchyma in pediatric patients. This report describes our preliminary findings with mini-PCNL using a 1.5-mm probe-size shock pulse lithotriptor. A 11-year-old child presented with multiple small inferior calyceal calculi. The patients were placed in Bartz flank-free modified supine position and underwent mini PCNL. The stone was fragmented using a 1.5-mm probe shock pulse lithotripter and fragments were suctioned out through the hollow probe...

This study aims to analyze the effects of climate parameters on the number of urolithiasis treatments in our hospital and understand the effects of climate parameters on the prevalence of urolithiasis in southern Taiwan. We also look at trends associated with urolithiasis and treatments. Retrospectively reviewed the records of extracorporeal shockwave lithotripsy (ESWL), ureteroscopy (URS), retrograde intrarenal surgery (RIRS), and percutaneous nephrolithotripsy (PCNL) performed in our hospital from January 2012 to December 2018...

OBJECTIVE: To evaluate the clinical value of mixed reality-assisted puncture navigation (MRAPN) in percutaneous nephrolithotripsy (PCNL). METHODS: Two hundred patients undergoing PCN were enrolled, all of whom had kidney stones to be subjected to lithotripsy by PCNL, and grouped according to surgical procedure into the MRAPN (n=100) and non-mixed reality-assisted puncture (non-MRAPN) (n=100) groups. CT data in DICOM format for all patients in the MRAPN group were imported into 3D reconstruction and mixed reality (MR) post-processing workstations, and holographic 3D visualization modelling...

Extracorporeal shockwave lithotripsy (ESWL) is the only non-invasive treatment for kidney stones. It does not require an operating room, anesthesia, or hospital stay. Its role evolved over the years and nowadays ESWL is slowly disappearing from many stone centers and urologic departments. We present the history and the role of ESWL treatment since its birth in 1959 and its development through the following years. We also present details of its application and impact on the first Italian stone center in 1985...

PURPOSE OF REVIEW: Kidney puncture is a key step in percutaneous nephrolithotomy (PCNL). Ultrasound/fluoroscopic-guided access to the collecting systems is commonly used in PCNL. Performing a puncture is often challenging in kidneys with congenital malformations or complex staghorn stones. We aim to perform a systematic review to examine data on in vivo applications, outcomes, and limitations of using artificial intelligence and robotics for access in PCNL. RECENT FINDINGS: The literature search was performed on November 2, 2022, using Embase, PubMed, and Google Scholar...

INTRODUCTION: Cystinuria is often diagnosed by large renal stone for pediatric patients. The patients suffer from recurrence of stone disease, develop the chronic kidney disease and fall into end-stage renal failure. Total removal of stone at the first intervention and prevention of recurrence are essential. Although, it is difficult to treat the pediatric stone patients for their anatomical feature. CASE PRESENTATION: We report three cases of pediatric cystine stone patients (two 4-year-old boys and a 9-year-old girl) successfully treated by mini-percutaneous nephrolithotripsy and antegrade ureteroscopy...

A 66-year-old man was diagnosed with renal allograft lithiasis. Although retrograde intrarenal surgery was attempted, a ureteral access sheath (UAS) was difficult to insert. Subsequently, we planned the endoscopic combined intrarenal surgery (ECIRS) using the "Sheath-connection technique." We indwelled the two UAS anterogradely and retrogradely, unified them at the bladder and the junction of the two UAS was passed through the ureterovesical junction. We successfully performed ECIRS.

PURPOSE: To evaluate the safety and efficacy of single-probe dual-energy (SPDE) lithotripters in patients undergoing percutaneous nephrolithotripsy (PCNL) through a systematic review and meta-analysis. METHODS: We searched PubMed, Cochrane Library, Scopus and Embase databases until July 2022 for any preclinical or clinical studies, exploring the safety and efficacy of different SPDE lithotripters in patients undergoing PCNL. We performed a meta-analysis to compare stone-free rate, bleeding, or other complications and mean operative time between SPDE lithotripters and other lithotripters (PROSPERO: CRD42021285631)...

PURPOSE OF THE STUDY: to study the safety and efficacy of using a new method of performing percutaneous nephrolithotripsy under ultrasound and endovisual control. MATERIALS AND METHODS: A comparative analysis of the results of percutaneous nephrolithotripsy performed under ultrasound and endovisual control in 515 (84.1%) patients (main group) and percutaneous nephrolithotripsy performed under fluoroscopic control in 97 (15.8%) patients (control group) was carried out...

INTRODUCTION: We report a case of abdominal compartment syndrome due to hydroperitoneum after endoscopic combined intrarenal surgery. CASE PRESENTATION: A 56-year-old woman with a left staghorn calculus underwent endoscopic combined intrarenal surgery as a two-staged procedure and developed a distended abdomen, cyanosis of both legs, and hypotension immediately after the second operation. A computed tomography scan showed hydroperitoneum. We performed urgent laparotomy and evacuated approximately 2 L of nearly transparent fluid...

OBJECTIVE: To compare and analyze the clinical effects of ultrasound-guided percutaneous nephrolithotripsy and X-ray-guided percutaneous nephrolithotripsy in the treatment of complex renal calculi without hydronephrosis. METHODS: Eighty patients with multiple stones without hydronephrosis were admitted at Department of Ultrasound Diagnosis, The first medical center of Chinese PLA General Hospital from January 21, 2020 to December 21, 2020 randomly divided: into two groups: experimental group and control group, with 40 cases in each group...

BACKGROUND: Percutaneous nephrolithotripsy (PCNL) is difficult to perform for elderly patients; thus, this study aimed to assess its efficacy and safety in elderly patients aged > 70 years, note any associations between outcomes and patient characteristics, and summarize relevant themes and observations. METHODS: Data from patients older than 70 years who had undergone PCNL for upper urinary tract calculi between January 2016 and January 2021 was retrospectively analyzed...

INTRODUCTION: The key point of successful PCNL is getting access to the renal collecting system. Ureteral catheterization and injection of contrast material provide an important advantage of visualizing and dilating the collecting system. However, catheterization increases the operation time, exposure to anesthesia, and requires additional reusable and disposable medical supplies. The purpose of the study was to develop a surgical algorithm for accessing the renal collecting system for mini-PCNL without catheterization...

OBJECTIVES: Management of postoperative pain following percutaneous nephrolithotripsy (PCNL) is a significant goal. We sought to identify risk factors and clinical correlates of postoperative pain in order to improve perioperative management and patient satisfaction. MATERIALS AND METHODS: A single-center, retrospective analysis, from a prospectively maintained database, of all consecutive patients who underwent PCNL for renal calculi between January 2011 and August 2018...

OBJECTIVE: The aim of the investigation was to determine the influence of such parametric characteristics of the stone such as size and volume on the duration of tulium laser disintegration of the urinary stone and to determine which of these parameters is more effective to use like prognostic criterion for the duration of the planned surgical intervention in the percutaneous nephrolithotripsy. MATERIALS AND METHODS: Overall 52 patients (27 females and 25 males) with an average age of 56,9 (25-79) years participated in the present study...

BACKGROUND AND AIM: The aim of this study is to validate a totally non biologic training model that combines the use of ultrasound and X ray to train Urologists and Residents in Urology in PerCutaneous NephroLithotripsy (PCNL). METHODS: The training pathway was divided into three modules: Module 1, related to the acquisition of basic UltraSound (US) skill on the kidney; Module 2, consisting of correct Nephrostomy placement; and Module 3, in which a complete PCNL was performed on the model...

An ectopic kidney is a rare developmental anomaly in which the kidney can be pelvic, iliac, abdominal, and thoracic, and affected patients are more prone to conditions such as reflux, pelvic ureteric junction (PUJ) obstruction, hydronephrosis, nephrolithiasis, and even renal failure than patients with normally structured kidneys. In this case, we present a 43-year-old male who is a known case of ectopic left pelvic kidney and presented with chronic lower abdominal pain. Upon imaging, it was revealed that he had a staghorn stone for which he underwent laparoscopy-assisted percutaneous nephrolithotripsy (PCNL)...

OBJECTIVES: To examine the age-related differences in the presentation, management, and outcomes of patients admitted to the emergency department (ED) with ureteral stones. PATIENTS AND METHODS: A retrospective analysis of all patients who visited the ED at a single institution that were found to have a ureteral stone on CT. Clinical, laboratory, and imaging parameters were collected, including outcomes. Patients were subdivided into age groups: 18-30, 31-50, 51-70, and >70 years...

Urinothorax is a rare cause of pleural effusion, which is seen in patients with obstructive uropathy, blunt trauma, or ureteric injury during abdominal surgical procedures. Clinical symptoms may include dyspnea, chest pain, cough, fever, abdominal pain, and decreased urine output. Diagnosis is made by thoracentesis, which would reveal fluid with a urine-like odor, and pleural fluid analysis, which would show if fluid is transudative in nature with a pH lower than 7.30. Pleural fluid to serum creatine ratio of more than 1 is diagnostic for this condition...
