PURPOSE: Pediatric stone disease is an important clinical problem in pediatric urology practice. We aimed to compare mini-percutaneous nephrolithotomy (miniperc) and micro-percutaneous nephrolithotomy (microperc) in pediatric patients who underwent unsuccesful SWL procedure. MATERIALS AND METHODS: A number of 43 pediatric patients, aged 17 years or younger, were treated with miniperc or microperc procedures due to renal calculi by a single surgeon. In group 1, there were 27 patients who underwent miniperc procedure...

OBJECTIVE: We aimed to present the technique of combination of standard percutaneous nephrolithotomy (PNL) with microperc for achieving higher success rates without increasing complication rates in the management of complex renal calculi. MATERIAL AND METHODS: The patients who underwent microperc procedure as a complementary procedure to standard PNL for complex kidney stones in two reference hospitals between 2013 and 2015, were evaluated retrospectively. RESULTS: All patients underwent a total of two accesses one for standard PNL and one for microperc...

BACKGROUND: Urinary stones disease is becoming more common not only in adults but also in children. Most cases are resolved with extracorporeal shock wave lithotripsy, but miniaturization of endoscopes has increased the use of ureteroscopy in resolving ureteral stones, most notably in children. CASE PRESENTATION: This presentation focuses on two cases of microureteroscopy. In both cases, the presence of lithiasis in the pelvic ureter was suspected to be the cause of ureter hydronephrosis, and a microureteroscopy was performed for treatment purposes...

Micropercutaneous nephrolithotomy (microperc) is a recently introduced percutaneous nephrolithotomy (PNL) technique that has the smallest tract size. The absence of an amplatz sheath during the microperc technique is a fundamental difference that distinguishes it from all other types of PNL (standard, mini, ultramini). Increasing of the intrarenal pelvic pressure (IPP) was demonstrated by the authors in adult patients but this problem may be even more serious in pediatric patients. Previously, the authors defined the use of a 14 gauge angiocath needle and sheath (microsheath) during microperc surgery for pediatric patient to reduce the IPP...

OBJECTIVE: To study kidney injury molecule-1 (KIM-1) biomarker levels, indicating renal tubular damage, in patients with kidney stones and in those who underwent minimally invasive method stone treatment. PATIENTS AND METHODS: Sixty patients with renal stones between 10 and 20 mm were included into the present study. Patients who were divided into three cohorts underwent micropercutaneous nephrolithotomy (microperc), retrograde intrarenal stone surgery (RIRS), and percutaneous nephrolithotomy (PNL)...

INTRODUCTION: For small renal calculi (< 2 cm) the currently available treatment options include extracorporeal shockwave lithotripsy (ESWL), retrograde intrarenal surgery (RIRS) and standard/mini percutaneous nephrolithotomy (PNL). A new method, microperc, has therefore been developed, in which a smaller tract size and smaller instruments were used. AIM: To present our clinical experiences with micropercutaneous nephrolithotripsy (microperc) in the treatment of small renal calculi...

The objective of this study was to audit the costs of retrograde intrarenal surgery (RIRS) and micropercutaneous nephrolithotomy (microperc) and compare them in terms of cost-effectiveness. We performed a retrospective analysis of 63 patients who underwent microperc and 48 patients who underwent RIRS. The cases, performed between first use and first repair, were used for this initial study. The costs associated with performing RIRS and microperc, including the costs of devices, disposables, hospitalization, and additional required treatments, were audited...

OBJECTIVE: We aimed to clarify the applicability and safety of micro-PNL (microperc) in the treatment of pediatric kidney stones. MATERIAL AND METHODS: A single center prospective trial was initiated, and microperc was performed in 40 children using the same two methods: the classical all-seeing needle and microsheath method. Stone fragmentation was performed using a 200-μm holmium:YAG laser fiber. RESULTS: The mean age of the patients was 6...

OBJECTIVES: To present our single-centre experience of the micropercutaneous nephrolithotomy (microperc) technique and define its role in the management of renal calculi as well as to analyse the factors predicting outcome. PATIENTS AND METHODS: We retrospectively analysed data from 139 patients who underwent microperc for renal calculi between June 2010 and November 2014 at our institution. The factors analysed were demographic variables, which included age, sex, stone volume, stone density (Hounsfield units [HU]) and stone location, and intra- and peri-operative variables, such as operating time, drop in haemoglobin level, stone clearance and complications...

Percutaneous nephrolithotomy is accepted as the standard management approach for kidney stones that are either refractory to extracorporeal shock wave lithotripsy or are >2 cm in diameter. The recently developed micro-percutaneous nephrolithotomy (microperc) technique provides intrarenal access under full vision using an optic instrument with a smaller calibration. A lesser amount of bleeding has been reported with the use of this method. Here we present a case of a bleeding complication on postoperative day 15 after a microperc procedure used to treat a left kidney stone...

The objective of this study was to present the outcomes of comparative clinical study of microperc versus mini-percutaneous nephrolithotomy (mini-PNL) in the treatment of lower calyx stones of 10-20 mm. Patients with lower calyx stones treated with microperc (Group-1) or mini-PNL (Group-2) between 2011 and 2014 were retrospectively analyzed. Demographics of the patients were compared, including age, gender, BMI, stone size, laterality and procedural parameters (operation and fluoroscopy time), and outcomes (success and complication rates)...

We present the treatment of lower pole stones of a 62-year-old male patient with a history of open partial nephrectomy due to renal angiomyolipoma and renal stones. He was successfully treated with micropercutaneous nephrolithotomy technique under spinal anesthesia in spite of fibrotic and scar tissue due to previous open surgery. The patient was stone-free and was discharged after a 24-hour hospitalization period. There is not any published report of micropercutaneous nephrolithotomy in a partial nephrectomized kidney before...

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...

The objective of the study was to present the clinical and operative effects of two types of anesthesia on micro-percutaneous nephrolithotomy ("microperc"). We retrospectively reviewed 116 patients who underwent microperc between August 2011 and September 2013. Patients were sorted into one of the two groups according to the type of anesthesia received: general (Group 1, n:53) or spinal (Group 2, n:63). Perioperative variables (age, stone size, location) and outcomes (operation time, success, complication rate) were evaluated and compared...

PATIENTS AND METHODS: A retrospective analysis of 112 patients who underwent microperc surgery between December 2012 and April 2014 was performed. Patients were evaluated in two groups according to whether the presence of hydronephrosis. Stone size and location, fluoroscopy and operation time, stone-free rates and patient-related parameters were prospectively recorded into a centralized computer-generated system...

OBJECTIVES: To present to report the first case of ureteral lithiasis resolved using a new endoscopic approach, which we call microureteroscopy (m-URS) and attempts to reduce the ureteral damage caused by conventional instrumentation. MATERIAL AND METHODS: We selected a 53-year-old patient with a 16-mm calculus in the right distal ureter. For endoscopic access, we used a 4.8 Fr sheath from the microperc set and fragmented the stone with a 230-micron laser fiber...
