OBJECTIVE: To assess the feasibility and safety of a novel flexible mini-nephroscope in minimally-invasive PCNL. Presumably, limiting the size and number of tracts during percutaneous-nephrolithotomy(PCNL) has the potential of decreasing the morbidity of the procedure. We present our experience with, this new technique. METHODS: A retrospective analysis of patients with multiple kidney stones treated with mini-PCNL combined with a novel flexible mini-nephroscope was performed...

In the present study, the clinical effects of flexible ureteroscopy lithotripsy (FURL) and percutaneous nephrolithotomy (PCNL) for the treatment of kidney stones of ≤2 cm was studied. Seventy-two patients with kidney stones were randomly divided into the FURL group (n=39) under ureteroscope lithotripsy with holmium laser and PCNL group (n=33) under PCNL with holmium laser and compared their clinical effects. At 3 months after the operation, the stone removal rate of the FURL group was significantly higher than that of the PCNL group...

BACKGROUND: To compare the treatment outcomes between percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) for the management of stones larger than 2 cm in patients with solitary kidney. METHODS: One hundred sixteen patients with a solitary kidney who underwent RIRS (n = 56) or PCNL (n = 60) for large renal stones (>2 cm) between Jan 2010 and Nov 2015 have been considered. The patients' characteristics, stone characteristics, operative time, incidence of complications, hospital stay, and stone-free rates (SFR) have been evaluated...

A 55-year-old male presented, in June 2013, with left flank pain. Investigations revealed a complete staghorn stone. He had undergone two sittings of extracorporeal shock wave lithotripsy (ESWL) in 2008 for left renal stone. One year subsequent to this, he was diagnosed with hypertension and diabetes. The management of complete staghorn stones in a single sitting is a difficult proposition. Percutaneous nephrolithotomy (PCNL) is the gold standard to manage such stones. The patient was subjected to PCNL, and complete clearance was achieved in one sitting...

INTRODUCTION: Numerous studies have reported on regional or national trends of stone disease treatment. However, no paper has yet examined the global trends of intervention for stone disease. METHODS AND MATERIALS: A systematic review of papers from 2004 to September 2016 for all English language articles reporting on trends of surgical treatment of stone disease was performed. Authors were contacted in the case of data not being clear. If the authors did not reply, data was estimated from graphs or tables...

OBJECTIVE: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. MATERIAL AND METHODS: Here we report our experience in two cadaveric transplant patients with urolithiasis...

INTRODUCTION AND OBJECTIVES: Sepsis remains one of the dreaded complications of percutaneous nephrolithotomy (PCNL). To analyze prospectively the preoperative and intraoperative factors that predict the occurrence of systemic inflammatory response syndrome (SIRS) in patients undergoing PCNL so that we can aggressively manage those patients from the preoperative period itself and avert the dangerous complications. MATERIALS AND METHODS: A prospective study was carried out between August 2012 and March 2013 including all patients who underwent PCNL...

AIM: The aim of the current trial was to evaluate the learning curve of access creation through solo ultrasonography (US)-guided percutaneous nephrolithotomy (PCNL), and clarify the technical details of the procedure. MATERIALS AND METHODS: We evaluated the first 240 solo US-guided PCNLs performed by one surgeon at our institution. The data including the puncture procedure, access characteristics, access-related complications and stone-free rates were assessed in four sequential groups...

PURPOSE OF REVIEW: Miniaturized percutaneous nephrolithotomy (PCNL) procedures have reached big popularity in the past years. Following the idea that decreasing the diameter of the instruments would decrease the complication rate instruments with outer diameter down to 4,8 Fr was established. In this review, we want to take a critical insight of the most popular miniaturized procedures, regarding the key advantages and disadvantages of the miniaturized instruments. RECENT FINDINGS: For all techniques displayed, a number of studies are available to support their effectivity in the given range of indication...

INTRODUCTION: Renal stone is one of the common entities occurring in our population. There are different treatment modalities of stones; out of those percutaneous nephrolithotomy is one of the most popular and effective for the renal and upper tract stones. This study is based to compare the safety and efficacy of spinal anaesthesia and general anaesthesia in PCNL. METHODS: In a randomized prospective study 60 patients were divided in two groups; group 1 (n=30) underwent PCNL in general anaesthesia and group 2 (n=30) underwent PCNL in spinal anaesthesia in prone position with the conventional technique...

OBJECTIVE: To examine the cost factors associated with ultrasound and fluoroscopic guidance for percutaneous nephrolithotomy (PCNL) and determine which method can be performed at a lower cost per case. METHODS: A cost comparison study was performed utilizing clinical data from a prospectively maintained research database. We included the most recent 33 consecutive ultrasound-guided PCNL cases in 2016 and the most recent 40 consecutive fluoroscopy-guided PCNL cases before the operative surgeon transitioned to ultrasound guidance in May 2014...

Spinal cord injury patients are at increased risk of developing nephrolithiasis and may require percutaneous nephrolithotomy for treatment of large stone burdens. Our objective was to compare outcomes of PCNL in SCI patients as compared to a matched cohort of non-SCI patients. Data from the Healthcare Cost and Utilization Project State Inpatient Database for Florida and California were used to identify patients by ICD-9 codes who underwent PCNL between 2007 and 2011. SCI was identified by having a paralysis diagnosis on the chronic comorbidity indicator...

OBJECTIVE: To compare the efficacy and safety of staged retrograde flexible ureteroscopic lithotripsy (FURS) and miniaturized percutaneous nephrolithotomy (m-PCNL) for treatment of renal stones of 2-4 cm in diameter. METHODS: This randomized controlled trial was conducted in 70 patients with renal stones of 2-4 cm in diameter admitted in our hospital between January 2013 and December 2015. The patients were randomized to receive staged FURS (35 cases) or m-PCNL (35 cases), and the total treatment time, total hospital stay after procedure, total medical cost, treatment success, decrease in hemoglobin level and complications were compared between the two groups...

PURPOSE: To evaluate the efficacy and safety of 0.1% tranexamic acid in irrigant fluid in reducing blood loss during PCNL. MATERIALS AND METHODS: The study involved 400 patients who were planned for PCNL and were prospectively randomized into two equal groups. In tranexamic group, 0.1% tranexamic acid was given in irrigant fluid, while in placebo group, distilled water was added to irrigant fluid during surgery. Operative data were recorded which included fall in hemoglobin, total blood loss, operative time, irrigation fluid, length of stay in hospital, requirement of blood transfusion, complications related to PCNL and adverse events of tranexamic acid...

OBJECTIVE: To present the experience of pediatric percutaneous nephrolithotomy (PCNL) of our center. MATERIALS AND METHODS: This study was conducted from 1995 to 2015, on patients <15 years of age having renal and upper ureteral stones who underwent PCNL. Stones were classified as per Guy's stone score (GSS). Standard bull's eye technique was used for subcostal puncture. To avoid supracostal puncture, puncture was done in full inspiration or by oblique tract...
