PURPOSE OF REVIEW: The role of PCNL and the expertise surrounding it has expanded in recent decades. Miniaturisation of equipment and instrument size has formed a part of this innovation. Although an increasing number of studies have been performed on miniaturised PCNL (Mi-PCNL) recently, a critical appraisal on these is lacking. We therefore conducted a systematic review of the literature to evaluate the efficacy, safety and feasibility of Mi-PCNL techniques (< 15 Fr). RECENT FINDINGS: A systematic review was conducted from 1990 to March 2017 on outcomes of Mi-PCNL [micro PCNL (m-PCNL) and ultra-mini PCNL (UMP)] in adult patients...

INTRODUCTION: Management of pediatric stone disease is challenging, with standard percutaneous nephrolithotomy (PCNL) having a good stone-free rate (SFR), but with associated high complication rates. Miniaturization of this technique has led to the rise of minimally invasive PCNL techniques such as micro (<10F) and ultra-mini (<15F) PCNL procedures. Our objective was to perform a systematic review of the literature to evaluate the success and complication rates of minimally invasive PCNL techniques in the pediatric age group (<18 years)...

INTRODUCTION: Miniaturization of instruments has changed the paradigms of percutaneous nephrolithotomy (PCNL). To date, however, few studies have analyzed the possible renal trauma generated by PCNL tract dilation. The purpose of this study is to evaluate and compare systematically the renal injury of all PNCL dilation techniques in pork kidneys (PK) and cadaveric kidney models (CK). MATERIAL AND METHODS: Twelve dilation devices were tested (from 4.8 to 30 French (Fr)) including micro- and mini- PCNL kits, the Alken dilation set, 20 and 30 ATM balloons and the Amplatz set...

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...

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: 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)...

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.
