OBJECTIVE: To introduce an emerging technique termed 'super-mini- percutaneous nephrolithotomy' (SMP) and describe its application in practice. METHODS: We described the technique of SMP in the treatment of renal stones with emphasis on the material, indications, technique procedure, advantages, and results. RESULTS: SMP refers to a 7 Ch. nephroscope placed through a 10-14 Ch. metal access sheath with functions of both irrigation and suction-evacuation, to achieve stone fragmentation via laser or pneumatic lithotripsy...

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...

Flexible ureteroscopy is a highly resolving surgery which is able to solve most renal lithiasis of any Urology Department, with very low economic impact. It is a technique that has helped to continue treatment when SWL couldn't, and also has reduced the number of percutaneous renal surgeries that we currently perform. In this paper, we try review three important features of the operation: Technique, minimal requirements that we need to perform this surgery in a Urology Department, and the different possibilities to treat the lithiasis with holmium laser...

Arbuscular mycorrhizal (AM) fungi can assist their hosts to cope with water stress and other abiotic stresses in different ways. In order to test whether AM plants have a greater capacity than control plants to cope with water stress, we investigated the water status and photosynthetic capacity of Lycium barbarum colonized or not by the AM fungus Rhizophagus irregularis under three water conditions during a hot summer. Sugar levels and transcriptional responses of both plant and AM fungus aquaporin genes in roots were analyzed...

The direct tracking of cells using fluorescent dyes is a constant challenge in cell therapy due to aggregation-induced quenching (ACQ) effect and biocompatibility issues. Here, we demonstrate the development of a biocompatible and highly efficient aggregation-induced emission (AIE)-active pseudorotaxane luminogen based on tetraphenylethene conjugated poly(ethylene glycol) (TPE-PEG2) (guest) and α-cyclodextrin (α-CD) (host). It is capable of showing significant fluorescent emission enhancement at the 400-600 nm range when excited at 388 nm, without increasing the concentration of AIE compound...

MATERIALS AND METHODS: We evaluated patients who underwent PNL or RIRS for renal stones ≥ 2 cm size betweenNovember 2011 and November 2014. Stone size, operation, fluoroscopy and hospitalization time, success rates,stone-free rates and complication rates were compared in both groups...

BACKGROUND: To compare the treatment outcomes between percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) for the management of stones larger than 2 cm in patients with solitary kidney. METHODS: One hundred sixteen patients with a solitary kidney who underwent RIRS (n = 56) or PCNL (n = 60) for large renal stones (>2 cm) between Jan 2010 and Nov 2015 have been considered. The patients' characteristics, stone characteristics, operative time, incidence of complications, hospital stay, and stone-free rates (SFR) have been evaluated...

PURPOSE: To investigate the effect of performing shockwave lithotripsy (SWL) before retrograde intrarenal surgery (RIRS) on the treatment outcomes of patients with nephrolithiasis. MATERIALS AND METHODS: The data of 189 patients with renal stones who underwent RIRS from July 2007 to July 2014 was reviewed retrospectively. Patients with stones larger than 1.5 cm were recommended to undergo SWL before RIRS. Patients were divided into 2 groups based on whether the preoperative SWL was performed (group 1, n=68) or not (group 2, n=121)...

OBJECTIVE: To assess the efficacy and safety of External Physical Vibration Lithecbole (EPVL) for the treatment of residual stone after retrograde intrarenal surgery (RIRS). MATERIALS AND METHODS: A total of 173 patients (128 male and 45 female) were selected for the study. All the patients had residual fragments after RIRS for the renal or upper ureteral stones. They were prospectively randomized into two groups, one received EPVL one week after RIRS (group ER), another only underwent RIRS as a control (group CR)...

The dimers [{(η(n)-ring)MCl}2(μ-Cl)2] ((η(n)-ring)M = (η(5)-C5Me5)Ir, (η(6)-p-MeC6H4iPr)Ru) react with the modified cysteines S-benzyl-l-cysteine (HL1) or S-benzyl-α-methyl-l-cysteine (HL2) affording cationic complexes of the formula [(η(n)-ring)MCl(κ(2)N,S-HL)]Cl (1, 2) in good yield. Addition of NaHCO3 to complexes 1 and 2 gave equilibrium mixtures of neutral [(η(n)-ring)MCl(κ(2)N,O-L)] (3, 4) and cationic [(η(n)-ring)M(κ(3)N,O,S-L)]Cl (6Cl, 7Cl) complexes. Similar mixtures were obtained in one-pot reaction by successive addition of the modified cysteine and NaHCO3 to the above formulated dimers...

Judicious structural design employing 2-quinolinecarboxaldehyde and 4-methylaniline was used to generate the Schiff base ligand (E)-4-methyl-N-((quinolin-2-yl)ethylidene)aniline (L). Five IIB complexes, namely, [ZnLCl2] (1), [ZnL(NO3)2] (2), [ZnL(OAc)2]3 (3), [CdL(OAc)2]3 (4), and [HgLCl2] (5) have been synthesized based on L. Single-crystal X-ray diffraction analysis indicates that complexes 1, 3 and 4 exhibit 3D networks, whereas 2 and 5 form 2D layers and 1D chains, respectively. TD-DFT calculations show a good correlation with the UV-vis absorption assigned to π → π* intraligand transitions...

Organic D-π-A materials, possessing intramolecular charge transfer, have attracted much scientific attention in recent years because of their potential applications in the development of organic light emitting devices (OLEDs). Two new compounds, A1 and A2, having a D-π-A skeleton have been synthesized and single crystals were grown by the solution growth technique. Both compounds were characterized for crystallographic, thermal and photophysical properties. Upon photo-excitation in the solid state, A1 showed very strong green light emission while A2 gave sky-blue emission with much lower intensity...

OBJECTIVES: We present our experience in single-stage bilateral retrograde intrarenal surgery (RIRS), analyzing the stone free rate (SFR), surgical time, hospital stay, pre- and post procedure creatinine, stone composition and complications. METHODS: Between April 2012 and February 2016, 24 RIRS were carried out in 12 patients with bilateral renal stones. Patients were 9 men and 3 women with a median age of 47.5 (range:55),IMC: 23.59 (range: 12.5). RESULTS: Mean number of stones per renal unit was 2...

OBJECTIVE: To evaluate the efficacy and safety of super-mini percutaneous nephrolithotomy (SMP) in the treatment of pediatric kidney stones. PATIENTS AND METHODS: We reviewed the records of 111 children with renal stones treated with SMP technique in four different centers between September 2014 and September 2015. The indications for SMP treatment in all these kids were either previously failed shock wave lithotripsy or retrograde intrarenal surgery approaches, according to their parents' preferences...

BACKGROUND: The applicability of urinary biomarkers and optical diagnostics in upper urinary tract carcinoma (UUTUC) are increasingly debated. To receive insight in the opinion of the urological community involved in this field, a survey was sent out to identify the most promising techniques and understand the need for new diagnostics. Primary objective of this study was to provide an overview of current diagnostics in upper urinary tract urothelial carcinoma. Secondary objectives of this study was to assess the need for additional diagnostic techniques in the current diagnostic work-up for UUT-UC and to assess knowledge of novel techniques...

PURPOSE: Irrigation-induced increase in intrarenal pressure is of concern because it may cause infection due to increased pyelovenous and pyelolymphatic absorption. This study is the first to compare prospectively the absorbed fluid volumes during percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS) for stones larger than 2 cm. MATERIALS AND METHODS: General anesthesia was applied to all patients. Isotonic solution containing 1 % ethanol was used as irrigation fluid...
