“…In this scenario, RIRS has been widely used and is recommended as the treatment of choice for small-to-medium-sized renal calculi. Recent advancements in laser lithotripsy and digital endoscopes have improved the stone-free rate (84.6%) [ 4 ]. Nevertheless, anatomic variations with multiple abnormalities demand expertise with unexpected findings as tortuous ureter makes the ureteral access sheath insertion difficult.…”

Anatomical variations in the pelvic ectopic kidney (PEK) present many challenges to stone treatment. Retrograde intrarenal surgery (RIRS) has emerged as the treatment of choice for small to medium stones. We present a case of delayed hemorrhage due to an arteriocaliceal fistula. A 57-year-old man with a 12 mm middle calyx stone was subjected to uneventful RIRS, despite a high grade of scope deflection. Recovery was unremarkable until 37 days after surgery when the patient started recurrent hematuria and clot retention. Renal angiography revealed a bleeding vessel from an arteriocaliceal fistula. Superselective arterial embolization was successfully performed. Anomalous collecting system and vasculature can increase the risk of complications in PEKs. Massive bleeding from unusual arterial blood supply was effectively treated by angioembolization.

“…Therefore, it seems that SUFURS represents an effective therapeutic approach in these challenging cases, characterized by a high SFR and few surgical related complications [16 && ,32]. On the contrary, although RIRS reduced operative time and less invasiveness, mini-PCNL could be another option for bigger kidney stones (>2 cm) and more complex situations with an acceptable SFR [31,33].…”

Purpose of reviewNowadays, due to the increase of imaging diagnosis, we identify easily renal anomalies, and we can choose between a wide range of armamentarium to treat symptomatic stones in those challenging cases. However, there is a lack of evidence and consensus on its use. The aim of this narrative review is to collect all the available data about safety and efficacity of retrograde intrarenal surgery (RIRS) in the treatment of kidney stones associated to a renal anomaly. Recent findingsRenal anomalies are uncommon findings and even more if it has to be associated with renal stones. After a literature review of the past 2 years, there are a small number of studies that compare the outcomes in patients who have been treated with minimally invasive modalities and they are mainly focus on RIRS.

“…There are two theories that explain the mechanism of kidney stone formation: the result of a violation of the colloidal composition of urine, in which abnormal crystallization of salts occurs, and the presence of a low-molecular organic matter of protein nature in the body as the basis for the formation of kidney stones. − …”

Experimental Calorimetric Study of Thermodynamic Properties of Two Magnesium Phosphates, MgHPO₄·3H₂O and MgKPO₄·6H₂O

A calorimetric and thermodynamic investigation of two magnesium phosphates, MgHPO4·3H2O(cr) and MgKPO4·6H2O(cr), was undertaken. The synthesis of both phases was performed from magnesium chloride and potassium phosphate solutions at room temperature. The synthetic products were characterized by powder X-ray diffraction and X-ray fluorescence methods. The enthalpies of formation of both phases were determined using hydrofluoric acid solution calorimetry giving Δf H m o(T = 298.15 K, MgHPO4·3H2O,cr) = −2595 ± 3 kJ mol–1 and Δf H m o(T = 298.15 K, MgKPO4·6H2O,cr) = −3718 ± 3 kJ mol–1. The low-temperature heat capacity, C p,m o, was measured using adiabatic calorimetry from T = 6.1 to 324.6 K for MgHPO4·3H2O(cr) and from T = 5.9 to 329.0 K for MgKPO4·6H2O(cr). Using these C p,m o(T) data, the third law entropy at T = 298.15 K, S m o, is calculated as 212.9 ± 1.5 J K–1 mol–1 for MgHPO4·3H2O(cr) and 352.7 ± 2.1 J K–1 mol–1 for MgKPO4·6H2O(cr). These new experimental results, together with literature data, are used to calculate the Gibbs free energy of formation, Δf G m o, for both phases, giving Δf G m o(=298.15 K, MgHPO4·3H2O,cr) = −2292 ± 4 kJ mol–1·and Δf G m(T = 298.15 K, MgKPO4·6H2O,cr) = −3248 ± 4 kJ mol–1. Smoothed C p,m o(T) values between 0 and 320 K are presented, along with the values for S m o and the functions [H m o(T) – H m o(0)] and [G m o(T) – H m o(0)], for both phases.
