Comparison of ultra-mini percutaneous nephrolithotomy and micro-percutaneous nephrolithotomy in moderate-size renal stones.

CONCLUSIONS: Two techniques have similar success and complication rates, and both may be preferred particularly in moderate-size stones. Our experience supports that our UPNL technique is safe and effective using with a standard ureteroscope. PMID: 28613207 [PubMed - in process]

CONCLUSION: The decrease in lasing time achieved by the Moses system does not translate into sufficient cost savings to off-set the higher cost of the laser fiber and software. PMID: 29900818 [PubMed - in process]

AbstractTo study the expression profiles of lncRNA and mRNA in the calcium oxalate monohydrate-attached HK-2 cells, and investigate the association between critical lncRNA expression level and renal injury. The HK-2 cells were treated with crystal suspension of calcium oxalate. The effects of calcium oxalate crystals on the growth of HK-2 cells were determined by MTT assay. Total RNA was extracted and the lncRNA and mRNA expression profiles were analyzed by high-throughput transcriptase sequencing platform HiSeq 2500. The profile of identified lncRNAs and mRNAs were verified by real-time PCR and their potential function wa...

AbstractTo assess the safety and efficacy of super-mini percutaneous nephrolithotomy (SMP) in the treatment of symptomatic lower pole renal stones (LPSs) after the failure of shockwave lithotripsy (SWL) or retrograde intrarenal surgery (RIRS), we retrospectively evaluated 44 patients with symptomatic LPSs with previously failed SWL or RIRS and consequently underwent SMP from October 2014 to March 2016. The percutaneous renal access was performed 12 –14F with C-arm fluoroscopy or ultrasonographic guidance. Stone disintegration was performed using either Holmium laser or pneumatic lithotripter. Perioperative parameters...

AbstractTo examine different locations and laser settings ’ effects on the efficiency of the “popcorn” method of laser lithotripsy, which consists of placing the laser in a group of small stones and firing continuously to break them into smaller particles. Pre-fragmented BegoStones were created between 2 and 4 mm to mimic typical popcorning conditio ns. A 0.5 g collection of fragments was placed into 3D-printed models (a spherical calyx and ellipsoid pelvis model) and a 200-µm laser fiber was positioned above the stones. The laser was fired for 2 min with irrigation, with 5 trials at ...

It is unknown whether benefits of medical management of urolithiasis outweigh potential side effects of utilized medications including potassium citrate (Kcit) and thiazide diuretics. Therefore, we sought to evaluate the relationship between Kcit or thiazides and overall stone-related health related quality of life (HRQOL).

AbstractIn rats, we recently showed how a chronic metabolic acidosis simultaneously reduced urinary oxalate excretion and promoted oxalate secretion by the distal colon leading to the proposition that acid –base disturbances may trigger changes to renal and intestinal oxalate handling. The present study sought to reproduce and extend these observations using the mouse model, where the availability of targeted gene knockouts (KOs) would offer future opportunities to reveal some of the underlying tran sporters and mechanisms involved. Mice were provided with a sustained load of acid (NH4Cl), base (NaHCO3) or the carbon...

Abstract PURPOSE: Comparison of efficiency and reliability of percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS) in treatment of multicalyceal and multiple renal stones in the same renal unit. MATERIALS AND METHODS: Between 2011 and 2015, records of patients who underwent surgery for renal stone were retrospectively reviewed. Patients who had multiple stones located in different calices in the same renal unit were included. The patients that underwent PNL and RIRS were defined as Group I and Group II, respectively. Patient criteria (age,sex); the stone characteristics; time of procedu...

In this study, we aimed to present the distribution of operation numbers for both percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) in terms of age and stone size in order to reveal the changes over the years. METHOD: Between January 2010 and March 2016, 1814 patients were operated for the treatment of renal stones. Patients were directed to the two different operations according to the surgeons' choices: RIRS or PCNL. Prospectively collected data was retrospectively reviewed. RESULTS: In the years 2010, 2011, 2012, 2013, 2014, 2015, and 2016, the number of RIRS applied for the treatment ...
