PURPOSE: To compare the efficacy and safety of Super-mini percutaneous nephrolithotomy (SMP, F12-F14) and Miniperc (F18) in the treatment of renal stones of 2-4 cm in size. METHODS: A prospective comparative analysis of outcomes of patients who underwent SMP and Miniperc for treatment of 2-4 cm renal stones was conducted between July 2014 and January 2017. Demographic data, stone criteria, operative technique, complications, blood transfusion, hemoglobin decrease, stone-free rate (SFR) and length of hospital stay were compared between the two groups...

Recent years have seen innovations in working armamentarium of percutaneous nephrolithotomy (PCNL) leading to development of novel modifications such as miniperc, ultra miniperc, and microperc. Amongst these microperc appears to be least invasive and various authors, off late, have reported their experience with the technique. Literature on microperc was reviewed by a MEDLINE/PubMed search with articles in the English language since 2011 in published peer-reviewed journals. Articles comprised of case series, comparative, and noncomparative studies...

INTRODUCTION: Reducing the percutaneous nephrolithotomy (PCNL) tract size reduces the morbidity associated with the procedure. Prolonged procedure time is a concern. Modification in technique required is to fragment the stone into smaller particles and remove them using the vacuum cleaner effect. This prospective study compares the efficacy and morbidity of reducing the tract size from the standard 24-16.5 Fr for stones sized from 16 to 30 mm. METHODS: 123 patients were enrolled in this prospective study and distributed into 2 groups based on the tract size used (group A 16...

INTRODUCTION: The progressive reduction in the calibre of the tract in percutaneous kidney surgery to the point of miniaturisation has expanded its use to smaller stones that until now have been treated with extracorporeal shock wave lithotripsy (ESWL) and retrograde intrarenal surgery (RIRS). OBJECTIVE: To provide an update on the various techniques of small-calibre nephrolithotomy (SC-PCNL) analyse their efficacy, safety and indications and determine their degree of implantation at this time...

OBJECTIVES: The objective of this article is to show the current situation regarding two surgical techniques for the treatment of renal lithiasis, RIRS (Retrograde intrarenal surgery) and PCNL (Percutaneous nephrolithotomy), specially concerning the larger size stones. We perform a literature review on the topic and add the experience with both techniques at our center. Besides, we also analyze the role of RIRS in comparison with the percutaneous techniques in smaller size lithiasis. METHODS: We review the results obtained in the literature and our experience...

OBJECTIVE: To apply urolithiasis scoring systems to the pediatric miniperc procedure and to compare their predictive capability for postoperative outcomes. MATERIALS AND METHODS: Records from 2 referral centers of patients under 18 years of age who had the miniperc procedure between 2010 and 2015 were retrospectively investigated. All patients included in the study were graded by the same surgeon according to Guy's and Clinical Research Office of the Endourological Society (CROES) scoring systems using preoperative imaging methods...

OBJECTIVE: The aim of the study was to compare the efficacy of the laser lithotripter with the ultrasonic lithotripter in mini percutaneous nephrolithotomy (miniperc). MATERIAL AND METHODS: From June 2013 to January 2014; medical records of 77 consecutive patients who underwent miniperc operation were retrospectively evaluated. Ultrasonic lithotripter was used in 22 patients (Group 1), while laser was used in 55 patients. In the laser group, 22 patients were randomly selected who had same characteristics compared to group 1 (Group 2)...

OBJECTIVE: To assess the safety and efficacy of Miniperc for renal stones in preschool-age patients. To the best of our knowledge, this may be the first prospective study on this subject. Reports on Miniperc are still few and mostly retrospective using a sheath size of ≥ 18Fr, which is still relatively large for young children. PATIENTS AND METHODS: From January 2012 to May 2013, Miniperc was performed for 26 children (≤ 6 years old) with renal calculi <5 cm through 14Fr sheath using a 9...

OBJECTIVE: To compare outcomes of micro-percutaneous nephrolithotomy (PNL; microperc) with mini-PNL (miniperc) in the treatment of pediatric renal stones of sizes 10-20 mm. MATERIALS AND METHODS: Patients aged <18 years who underwent PNL for renal stones of sizes 10-20 mm between August 2011 and March 2014 in 3 referral centers were reviewed retrospectively. Patients were evaluated in the following 2 groups: microperc (group 1) and miniperc (group 2). Demographics and perioperative parameters (fluoroscopy and operation time, hemoglobin drop, and stone-free and complication rates) were retrospectively analyzed...

CONTEXT: Extracorporeal shock wave lithotripsy (ESWL) and percutaneous nephrolithotomy (PCNL) are consolidated procedures for the treatment of kidney stones; however, their primary weak points are the lower efficacy of ESWL, especially for lower calyx stones, and the morbidity of PCNL resulting from the creation and dilation of the percutaneous trajectory. The increasing miniaturization of percutaneous surgery instrumentation and the development of retrograde intrarenal surgery (RIRS) are recent innovations...

PURPOSE: We analyzed results of percutaneous endopyelotomy for treatment of recurrent ureteropelvic junction obstruction in children with failed primary pyeloplasty. MATERIALS AND METHODS: We retrospectively studied all patients treated at our department for recurrent ureteropelvic junction obstruction between 2009 and 2013. All procedures were performed using a 12Fr miniperc approach with the patient in the supine position. A high pressure balloon was inflated at the ureteropelvic junction obstruction...

INTRODUCTION: The indications for PCNL have seen a paradigm shift in the past decade. In the earlier years, PCNL was done for large-volume stones such as complex multiple calyceal calculi, staghorn stones. The advent of miniaturization of instruments ushered in smaller scopes, smaller retrieval devices, and energy sources. The miniaturization of instruments also was responsible in the paradigm shift in the indications for PCNL. These miniaturized instruments and accessories obviate the need to dilate the tract beyond 20 Fr...

BACKGROUND AND PURPOSE: The purpose of this study is to evaluate the outcomes of miniperc at our center. PATIENTS AND METHODS: This is a retrospective review of consecutive 318 minipercs done in a single tertiary urological center. The Miniperc system used was either Wolf (Richard Wolf) 14F with 20F Amplaz sheath or Storz (Karl Storz) nephroscope 12F with 15/18F sheath or 16.5/19.5F sheath. Data about the demography of patients, comorbidities, stone size, number and size of the tract, size of nephroscope, energy source used, total operative time, exit strategy, hospital stay, clearance of stones, total analgesic requirement, visual analogue pain score at 6 and 24 hours, hemoglobin drop and complications were analyzed by the chi-square test and analysis of variance test...
