Stone disease has afflicted mankind since centuries; records from ancient civilisations of India and Egypt have shown stones in human bodies. The scientific mind of humans has always made smart endeavours to remove the kidney stones. From large instruments made like the beaks of different animals and birds in 600 BC (Indian civilisation) to extremely sophisticated and miniaturised endoscopic intruments of today the human race has travelled a long way. The theme has always been to remove the stones with minimal morbidity and mortality and with minimum pain to the patient...

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) has undergone significant changes in recent years in the quest for improving efficacy and reducing morbidity. Newer minimally-invasive modalities of PCNL such as mini-PCNL, ultra-mini PCNL, and micro-PCNL have evolved with advancement in optics and technology. However, with these newer advancements, migration of small fragments produced with laser lithotripsy remains a concern, which may result in incomplete stone clearance. We describe a new technique of PCNL termed "Superperc", that utilizes suction to remove all the fragments and maintain one-way flow...

New minimally invasive percutaneous nephrolithotomy (PCNL) techniques have changed the management of renal stones. We discuss the technological advances in PCNL and explain the meaning, requirements and set up costs for each of these 'newer' techniques.

CONTEXT: Percutaneous nephrolithotomy (PCNL) is the surgical standard for treating large or complex renal stones. Since its inception, the technique of PCNL has undergone many modifications. OBJECTIVE: To perform a collaborative review on the latest evidence related to outcomes and innovations in the practice of PCNL since 2000. EVIDENCE ACQUISITION: A literature review was performed using the PubMed database between 2000 and July 2015, restricted to human species, adults, and the English language...

Management of kidney stone disease in pediatric population is a challenging condition in urology practice. While the incidence of kidney stone is increasing in those group, technological innovations have conrtibuted to the development of minimally invasive treatment of urinary stone disease such as mini-percutenous nephrolitotomy (mini-PCNL), micro-PCNL, ultra mini-PCNL. In this review we tried to evaluate the effect of new teratment techniques on pediatric kidney stones.

BACKGROUND: Percutaneous nephrolithotripsy (PCNL) is one of the main interventional treatment modalities for large kidney stones (> 2 cm diameter). With the implementation of miniaturised techniques the indications for PCNL have been broadened to smaller stones. Especially for urologists without emphasis on endourology it is difficult to have an overview of the growing multitude of available systems and techniques. This article describes the currently available systems for percutaneous stone treatment with their peculiarities and indications...

BACKGROUND AND PURPOSE: Miniatured percutaneous nephrolithotomy (PCNL) techniques such as micro-PCNL (microperc) and ultramini-PCNL (UMP) are usually indicated for renal stones <2 cm. We present our preliminary report of treating patients with 2 to 3 cm renal stones using UMP in a semisupine combined lithotomy position associated with a retrograde ureteral access sheath (UAS). METHODS: From April 2013 to January 2014, we implemented 13F UMP for 22 patients with renal stones that were 2 to 3 cm with the patient positioned in a 45-degree semisupine combined lithotomy position...

Renal stone disease is becoming increasingly prevalent globally. With a rise in stone disease worldwide, there is also a relative increase in the rates of surgical intervention. Technological advances have allowed a move towards minimising the complications rates and length of stay with a reduction in invasiveness and size of instruments. A trend for minimising the percutaneous tract size has been noted in percutaneous nephrolithotomy (PCNL) for renal stones. The management has shifted from open surgery to standard PCNL, mini-PCNL and the latest ultra-mini and micro-PCNL techniques...

INTRODUCTION: The treatment of stone disease is mostly similar in those adult and children. The standard treatment procedures are as follows: extracorporeal shock wave lithotripsy (ESWL), ureterorenoscopy (URS), percutaneous nephrolithotomy (PCNL), and laparoscopic surgery in selected cases. Open surgery (OS) is another option particularly in such cases with anatomic abnormalities of urinary tract. OBJECTIVE: The present study aims to provide comparative results of stone removal procedures in preschool aged patients who were diagnosed with urinary system stone disease...

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) is a standard, safe, and efficient method for removing large renal calculi. Despite development of endourologic equipment, complications of the PCNL are still prevalent. Even though therapeutic modalities such as mini-micro PCNL have been developed in recent years, the complications are a serious concern yet. The most important complication is hemorrhage. The hemorrhage may be either arterial or venous. Venous hemorrhage is usually treated conservatively whereas the arterial one might require transarterial embolization (TAE)...

The objective is to evaluate clinical indications and safety of tubeless percutaneous nephrolithotomy (PCNL) for the treatment of stones in upper urinary tract. A total of 231 subjects accepted to undergo tubeless PCNL, both micro-channel and standard operation were performed. After PCNL, renal gastrostomy tube was not placed also catheters and double-J stents were subsequently removed 3-5 and 14-28 days, respectively. Primary PCNL resulted in stone clearance of 98.27 %. There were five cases of postoperative hemorrhage with bleeding of about 500 ml, which was stopped by keeping patients in bed and medication...

Ever smaller miniaturised techniques are being developed for percutaneous nephrolithotomy (PCNL), with access sheaths now as small as 4.8Fr being used in adults. With the ever expanding use of the terms "micro" "mini" or "ultra" techniques, the terminology can be somewhat confusing. We propose a simple classification system to standardise the terminology for PCNL, encapsulating technological and procedural advancements.

CONTEXT: Recent advances in technology have led to the implementation of mini- and micro-percutaneous nephrolithotomy (PCNL) as well as retrograde intrarenal surgery (RIRS) in the management of kidney stones. OBJECTIVE: To provide a systematic review and meta-analysis of studies comparing RIRS with PCNL techniques for the treatment of kidney stones. EVIDENCE ACQUISITION: A systematic literature review was performed in March 2014 using the PubMed, Scopus, and Web of Science databases to identify relevant studies...

PURPOSE: To review the incidence of UTIs, post-operative fever, and risk factors for post-operative fever in PCNL patients. MATERIALS AND METHODS: Between 2007 and 2009, consecutive PCNL patients were enrolled from 96 centers participating in the PCNL Global Study. Only data from patients with pre-operative urine samples and who received antibiotic prophylaxis were included. Pre-operative bladder urine culture and post-operative fever (>38.5°C) were assessed...

PURPOSE OF REVIEW: Miniaturization of instruments in percutaneous nephrolithotomy (PCNL) has spawned an interest in so-called 'microperc' in which the procedure is carried out through 16-gauge needle. RECENT FINDINGS: The greatest limitation of extracorporeal shock wave lithotripsy is its unpredictable results. The main limitation of retrograde intrarenal surgery is high sustainable cost and poor durability. The main limitation of PCNL is its invasiveness and associated morbidity...

OBJECTIVE: Stone disease in children differs in pathogenesis, presentation and in treatment from adults. In recent years, big changes on its management have occurred. We reviewed our experience on upper tract urinary calculi in paediatric age. MATERIAL AND METHODS: Patients observed for upper tract urinary stones from June 2002 to June 2008 were reviewed. Bladder-urethral calculi were excluded. Presenting symptoms had a wide range: macro- or micro-hematuria, recurrent abdominal or flank pain, or non-specific symptoms such as irritability and failure to thrive...
