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...

The incidence of stone disease has been increasing and the risk of recurrent stone formation is high in a pediatric population. It is crucial to use the most effective method with the primary goal of complete stone removal to prevent recurrence from residual fragments. While extracorporeal shock wave lithotripsy (ESWL) is still considered first line therapy in many clinics for urinary tract stones in children, endoscopic techniques are widely preferred due to miniaturization of instruments and evolution of surgical techniques...

The incidence of pediatric stone disease has been increasing. Though there are geographical variations, there remains a common theme in that this is a high-risk population with regard to stone formation and recurrence. Consequently, it is important to keep the number of procedures performed to a minimum and to save the developing kidney from the deleterious effects of intervention. Of the number of available treatment options, Percutaneous Nephrolithotomy (PCNL) offers a number of distinct advantages albeit with its own set of concerns...

Matjaz Perc, Attila Szolnoki
Prevalence of cooperation within groups of selfish individuals is puzzling in that it contradicts with the basic premise of natural selection. Favoring players with higher fitness, the latter is key for understanding the challenges faced by cooperators when competing with defectors. Evolutionary game theory provides a competent theoretical framework for addressing the subtleties of cooperation in such situations, which are known as social dilemmas. Recent advances point towards the fact that the evolution of strategies alone may be insufficient to fully exploit the benefits offered by cooperative behavior...

Minimally invasive percutaneous nephrolithopaxy (MIP) was developed to combine the excellent stone-free rates of the conventional percutaneous nephrolithopaxy (PCNL) technique with the low morbidity of the miniaturized PCNL (Mini-Perc) and, at the same time, achieve a high level of patient comfort. The procedure is characterized not only by the diameter of the miniaturized 18-Fr Amplatz sheath that was adopted from the Mini-Perc but also by the following features: ultrasound-guided puncture of the kidney; single-step dilatation of the access tract; ballistic lithotripsy; a low-pressure irrigation system together with stone retraction by irrigation with a specially designed nephroscope sheath, for the so-called vacuum cleaner effect; and a sealed and tubeless access tract with primary closure of the channel independent of hemorrhage and without a second-look procedure...

INTRODUCTION: Pediatric renal calculus disease has been considered a management dilemma. The various treatment modalities have different effects on the growing kidney, with concern to the significant recurrence rate, and the long-term outcome. We report our experience with performing percutaneous nephrolithotomy (PCNL) monotherapy in staghorn or complex pediatric renal calculi. PATIENTS AND METHODS: We retrospectively analyzed the results of PCNL in 9 children treated at our institute between 2001 and 2006...

So far extracorporal shockwave lithotripsy (SWL) is the treatment of choice for upper urinary tract stones. Since the introduction of new minimal-invasive endourological procedures, such as retrograde flexible uretero-renoscopy (fURS) and minimal-invasive percutaneous nephrolithotomy (Mini-Perc), alternative treatment modalities are available, which show enhanced stone-free rates and decreased treatment morbidity even in unfavorable stone localizations of the lower calix and calyceal diverticulum stones. In experienced hands modern endourological approaches are suitable as first-line treatment of upper urinary tract stones...

Extracorporeal shock wave lithotripsy (SWL) is the current treatment modality of choice for upper urinary tract calculi. For stones with a diameter >2 cm and in lower calyceal stones and diverticular stones, the stone-free rate of SWL is rather poor. In these cases, conventional percutaneous nephrolithotomy (PCNL) leads to an increased stone-free rate, but morbidity with conventional PCNL is significant higher than in SWL. With the invention of miniaturized nephroscopes (mini-perc), new treatment options are available...

BACKGROUND AND PURPOSE: Caliceal diverticula can be treated with a variety of techniques. Traditional percutaneous techniques utilize nephrostomy-tract dilation to between 26F and 32F. Identification of a small diverticulum can be difficult after such dilation. The mini-percutaneous nephrolithotomy technique has been described for the treatment of nephrolithiasis. We report on two patients with caliceal diverticula treated using a mini-perc technique with long-term follow-up. PATIENTS AND METHODS: Two symptomatic patients underwent treatment of posterior caliceal diverticula using a mini-perc technique...

Extra corporeal shock wave lithotripsy (ESWL) has significantly modified the management of urinary lithiasis. It constitutes usually the first line treatment of urinary calculi sized less than 30 mm. Complex and staghorn calculi may be treated either with percutaneous nephrolithotomy (PCNL) or by flexible uteroscopy (URS) with Holmium laser. PCNL is a minimal invasive technique but it carries a potential risk of complications: infection, bleeding, urinary fistulas and perforations of adjacent organs. PCNL complications may be prevented by the strict respect of technical recommendations; their therapeutic management has been properly codified...

Urolithiasis in children is a rare disease in developed countries. Due to the particular anatomical conditions of the infant body, indications and results of the well-known treatment modalities, such as shockwave lithotripsy (SWL), ureteroscopy and PCNL, have to be determined. Experience in active stone treatment in children is very rare and only a limited number of papers are available. SWL can be performed only if focus size and treatment facilities are adapted to the size of the child. Miniaturization of ureteroscopes allows primary access to the infant upper urinary tract...
