OBJECTIVES: Corpus callosotomy (CC) is used to reduce seizures, primarily in patients with generalized drug resistant epilepsy (DRE). The invasive nature of the procedure contribute to underutilization despite potential superiority to other palliative procedures. The goal of this study was to use a multi-institutional epilepsy surgery database to characterize the use of CC across participating centers. METHODS: Data was acquired from the Pediatric Epilepsy Research Consortium (PERC) Surgery Database, a prospective observational study collecting data on children 0-18 years referred for surgical evaluation of DRE across 22 US pediatric epilepsy centers...

The purpose was to do a study to compare infectious complications in patients operated for MiniPerc or Minimally invasive Percutaneous Nephrolithotomy (MPCNL) using MIP and MPCNL with suction using Shah Superperc sheath for medium-sized renal stones less than 3 cm in size. The primary objective of this study is to compare the infectious complications and the secondary objectives are to compare stone-free rates, complication rates and operative times. A prospective randomized controlled trial with patients having proximal ureteral and renal stones of 10-30 mm size and planned for MPCNL done at a single institute...

OBJECTIVE: To summarize recent advancements in mini-percutaneous nephrolithotomy (mini-PCNL) in surgical technique, stone removal strategy, lithotripsy, and surgical model from the current literature. METHODS: We conducted a narrative review of relevant English-language articles up to October 2022 using the PubMed and Web of Science databases. The following keywords were used in the search: "percutaneous nephrolithotomy", "minimally invasive percutaneous nephrolithotomy", "mini-PCNL", "mini-perc", "mPCNL", and "miniaturization"...

OBJECTIVE: The choice of lithotripter is an important part of planning in mini-percutaneous nephrolithotomy (mini perc) as the operating time is prolonged due to reduced sheath size and smaller working channel. Previous studies mostly reported the use of laser lithotripter for stone fragmentation while the literature on pneumatic lithotripter use in miniperc is scant. METHODS: In this study, we compared the efficacy and safety of the laser lithotripter (LL) vs pneumatic lithotripter (PL) in miniperc for small to medium-sized renal/upper ureteric stones (size: 1-2 cm)...

Lower pole renal stones present a significant challenge in urologic practice due to difficulty in accessing the calyx and eliminating fragments. Management options for these stones include watchful waiting for asymptomatic stones, extracorporeal shock wave lithotripsy (ESWL), ureterorenoscopy (URS), and percutaneous nephrolithotomy (PCNL). Mini-PCNL is a newer modification of conventional PCNL. The study aimed to assess the feasibility of mini-PCNL in treating lower pole renal stones equal to or less than 20mm that were not responsive to ESWL therapy...

INTRODUCTION: PCNL remains the gold standard for larger kidney stones. Reducing the operating time of PCNL and its complication rate seems to be the next logical step in optimizing this classical technique. To achieve these objectives, some new methods of lithotripsy emerge. We present the data of a single, high-volume, academic center with combined ultrasonic and ballistic lithotripsy in PCNL using the Swiss LithoClast® Trilogy device. MATERIALS AND METHODS: We designed a prospective, randomized study including patients who underwent PCNL or miniPerc with lithotripsy using the new EMS Lithoclast Trilogy or EMS Lithoclast Master...

AIM: The aim of this study was to analyze the outcomes of miniaturized nephrolithotomy (mini-perc) in the management of renal stones with a diameter smaller than 20 mm. MATERIALS AND METHODS: We retrospectively reviewed the records of 102 patients who underwent mini-perc between March 2015 and March 2020 in our department. The primary objective was the stone-free rate, but we also analyzed the retreatment rate, complications, hospital stay, operative time and reduction in hemoglobin level...

Aim and Objectives: The aim of this study is to demonstrate the outcomes of retrograde intrarenal surgery (RIRS) and Mini percutaneous nephrolithotomy (M-PCNL) in the management of 1-2 cm renal stones, with factors considered being operative time, duration of hospital stay, complication rate, and auxiliary procedure rate. Materials and Methods: This is a single-center, prospective study on patients diagnosed with 1-2 cm renal calculi between April 2018 and March 2020...

INTRODUCTION: Renal stones are a frequent cause of morbidity globally. The number of lumbotomies performed for benign lithiasis has been greatly decreased with the usage of Percutaneous Nephrolithotomy (PCNL). Further development is aimed at reducing tract size, leading to numerous advanced minimally invasive PCNL procedures like mini-PERC, ultra-mini-PERC, and micro-PERC. The aim of this study was to evaluate whether tubeless or totally tubeless PCNL is the safest and most efficient, less morbid management technique for renal stones compared to the standard PCNL with a nephrostomy tube...

BACKGROUND: Limited literature has focused on the use of totally tubeless mini-percutaneous nephrolithotomy (PCNL) for the treatment of large renal stones. We present our findings of treating patients with large and/or complex renal stones using single renal access totally tubeless mini-PCNL. METHODS: From March 2018 to May 2021, 62 consecutive cases in which single tract totally tubeless mini-PCNL was used to treat complex renal stones were enrolled, all with calculi > 2 cm...

Background Uretero-pelvic junction obstruction (UPJO) is a common cause of upper tract urinary obstruction. This condition is generally treated with various surgical options which include endoscopic (retrograde or anterograde), laparoscopic, open or robotic-assisted approaches. Herein, we describe a novel endoscopic retropelvic extra-luminal approach using a mini (14 Fr) nephroscope. Methods A 30-year-old male presented with symptomatic left UPJO and inferior pole renal stones, which were identified on computed tomography (CT) imaging...

Percutaneous Nephrolithotomy (PCNL) has evolved over the decades from Standard to Mini to Ultramini PCNL to Micro-perc, with miniaturisation being the dominant theme and supine approach gaining momentum world over. Aim: In literature, miniaturised PCNL with microperc needle access system has raised concerns of intrarenal pressure and has some limitations with its success for larger stones. Our tips and tricks explain how to overcome these pitfalls by utilising the full construct of the needle system to its maximum potential...

INTRODUCTION: Bladder stones in children can often be challenging to manage. We present our experience of minimally invasive percutaneous cystolithotripsy using 'mini-perc' instruments in the treatment of the bladder stones in pre-school children. The study also compares the outcomes of mini-percutaneous cystolithotripsy (mPCCL) and transurethral cystolithotripsy (TUC). OBJECTIVE: We hypothesized that mPCCL is a new minimally invasive technique with comparable outcomes to TUC...

We report two cases of male patients with pelvic ectopic kidney with large stones cleared with laparoscopic-assisted minimally invasive percutaneous nephrolithotomy (Mini-PERC) and holmium laser. These are the first cases of Mini-PERC done for pelvic ectopic kidney reported thus far.

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...

PURPOSE: Currently, most ESRD patients are treated with open surgical technique or with laparoscopic technique. In this study, we examined the role of the ureteroscope-assisted "Mini-Perc" technique versus the modified open surgery in the treatment of ESRD in a prospective randomized manner. METHODS: A total of 72 patients with chronic renal failure were prospectively randomized for the ureteroscope-assisted "Mini-Perc" technique or modified open surgery. Intraoperative and postoperative morbidity, incision size, dose of local anesthesia, operative time, hospital stay, and initial catheter survival and follow-up were compared for both methods...
