Endoscopic treatment is currently the mainstay of management for urolithiasis. The high effectiveness of PCNL is well documented in the literature, as are its complications. Bleeding during PCNL is directly related to the size of the dilatation.(1) Several minimally invasive refinements in percutaneous surgery have been made to reduce access related complications and bleeding rates.(2) This was achieved mainly by reducing tract diameter, but the advantage over standard PCNL has yet to be proven.(3) The effectiveness of RIRS is decreasing with increasing stone burden...

OBJECTIVE: A wide selection of both anterograde and retrograde mini-invasive procedures exist for stones' treatment. The 2016 European Association of Urology (EAU) guidelines still don't univocally define a best option. Our purpose is to give an overview on some European Stone Centers' customs and to compare real life clinical practice with statements of opinion leaders and Guidelines. MATERIALS AND METHODS: In 2015 we performed a survey in 3 step about the spread of retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) techniques among EAU Section of Urolithiasis (EULIS) members...

INTRODUCTION: Shock wave lithotripsy (SWL) is the treatment of choice for most cases of renal lithiasis in children. Some cases, however, are refractory to SWL and may be associated with anatomic and metabolic changes or a large stone burden. In these circumstances, mini-percutaneous nephrolithotomy (mini-PCNL) is an option. OBJECTIVE: The aim was to assess the safety and efficacy of high-power holmium YAG (Ho:YAG) laser in mini-PCNL for staghorn calculi. PATIENTS AND METHODS: The clinical records relating to 35 mini-PCNLs (Table) performed between January 2008 and December 2012 in 33 patients (27 boys and 6 girls; mean age 7 years, range 2-18 years) were retrospectively reviewed...

We aim to compare the outcomes, including the morbidity and success rates in children undergoing percutaneous nephrolithotomy (PCNL) using different sized devices. According to the size of instruments used during surgery, three different groups (ultra-mini-PCNL, mini-PCNL and adult size PCNL) were composed and the outcomes were compared between the groups. PCNL was applied to 225 renal units of 220 children, including 5 patients with bilateral kidney stones. Percutaneous nephrolithotomy was performed using adult instruments (24 F) in 82 renal units, using pediatric instruments (18 F) in 89 and using minimal-size instruments (9...

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) has witnessed rapid advancements, the latest being ultra-mini-percutaneous nephrolithotomy (UMP), which makes the use of 11-13F sheaths as compared to 24-30F sizes used in conventional PCNL. This miniaturization aims to reduce morbidity and improve patient outcomes. We evaluated the safety and efficacy of UMP and report our ourtcomes. PATIENTS AND METHODS: A total of 120 patients underwent UMP from July 2012 to March 2014...

Strict selection of patients for minimally invasive percutaneous nephrolithotomy could effectively improve the success rate of surgery. This study aimed to understand the required skills and the efficacy of mini-PCNL in the treatment of five types of upper ureteral calculi. Data collected after X-ray analysis and B mode ultrasound from 633 patients with upper ureteral and renal pelvis calculi who underwent B ultrasound-guided lithotomy was reviewed, including the following: type I, upper ureteral or renal pelvis calculi with moderate hydronephrosis (154 cases); type II, upper ureteral or renal pelvis calculi with severe hydronephrosis (157 cases); type III, upper ureteral or renal pelvis calculi without hydronephrosis (61 cases); type IV, renal pelvis calculi, one or two renal calyx calculi (206 cases); and type V, renal staghorn calculi (55 cases)...

OBJECTIVE: To prospectively compare the outcome of standard mini-percutaneous nephrolithotomy (SmPCNL) versus tubeless mini-percutaneous nephrolithotomy (TmPCNL) as primary treatments of renal stones. PATIENTS AND METHODS: In all, 80 patients with a solitary radio-opaque renal stone and candidates for PCNL were selected. The patients were randomly divided into two groups of 40, one group treated with SmPCNL and the other with TmPCNL. Patients and stone characters, as well as operative and postoperative data of both groups were compared and statistically analysed...

Minimally invasive endoscopic procedures are often employed for the surgical removal of kidney stones. Traditionally, large stones are removed by (standard) percutaneous nephrolithotomy (SPCNL). Although effective for the clearance of large stone burdens, SPCNL is associated with significant morbidity. Therefore, in an effort to reduce this morbidity, while preserving efficacy, mini-PCNL (MPCNL) with a smaller tract size (<20 French) was developed. Several studies suggest that MPCNL has a comparable stone-free rate to SPCNL...

PURPOSE: Staghorn renal stones are a challenging field in urology. Due to their high recurrence rates, particularly those associated with an infective process, a complete removal is the ultimate goal in their management. We report our experience with a combined approach of laparoscopic pyelolithotomy and endoscopic pyelolithotripsy, the stone clearance rate, and long-term, follow-up outcomes. METHODS: From June 2012 to October 2014, nine adult patients with large staghorn renal calculi (mean size, 7...

INTRODUCTION: The treatment of renal lithiasis has undergone a sea change with the advent of extracorporeal shock wave lithotripsy (ESWL) and endourological procedures such as percutaneous nephrolithotomy (PCNL), ureterorenoscopy and retrograde intrarenal surgery (RIRS). The presence of anatomical anomalies, such as ectopic pelvic kidney, imposes limitations to such therapeutic procedures. This study is aimed to find a simple and effective way to treat the stones in ectopic kidney. MATERIALS AND METHODS: From 2010 to 2014, nine patients underwent laparoscopic-assisted mini PCNL with Laser dusting for calculi in ectopic pelvic kidneys at our hospital...

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.

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) was described in the 1980s and revolutionized the treatment of stone disease. The crucial component to this surgery is satisfactory track creation. We examine how the development and production in the 1980s of a single stage dilator (SSD) subsequently modified for pediatric PCNL has become the ideal access tool for mini percutaneous nephrolithotomy (mPCNL) today. MATERIALS AND METHODS: The conception, production, scientific and clinical development of the original SSD is described...

OBJECTIVE: To compare miniaturized percutaneous nephrolithotomy (mini-PCNL) and retrograde intrarenal surgery (RIRS) in the management of renal stones >10 mm in a single session. METHODS: Seventy patients presenting with renal stones >10 mm were randomized to a mini-PCNL or an RIRS group in a ratio of 1:1. Randomization was performed by a biostatistician and opened to the surgeon at the time of the patient's admission on the day before surgery. Patient and stone characteristics, perioperative outcomes, and complications were compared between the 2 groups...

UNLABELLED: To investigate the efficacy and safety of mini-percutaneous nephrolithotomy (mini-PCNL) under total ultrasonography in patients aged <3 years. METHODS: We reviewed 56 patients (67 renal units) aged <3 years between August 2006 and December 2012 in our units, including 31 renal units with a single stone, 6 with staghorn stones, 10 with upper ureteral stones, and 20 with multiple stones. The mean age of the patients was 24 (range 6-36) months and the mean maximum stone diameter was 18...
