Endourology has undergone fundamental changes over the last 2decades. Maintaining low intrarenal pressure (IRP) during upper urinary tract procedures is an established concept. However, researchers have not yet studied the concept of reduced intravesical pressures (IVPs) during transurethral (TUR) surgery as thoroughly. Low IVP is supposed to decrease complications as fluid retention, TUR syndrome, and incidence of fever. The study aims to give an overview of the contemporarily existing concepts and specify the term of low IVP to avoid TUR-related complications and optimize TUR-related results. A literature search was performed using PubMed, restricted to original English-written articles, including animal, artificial model, and human studies. Different keywords were transurethral resection, transurethral enucleation, transurethral vaporization, pressure, fluid absorption, and TUR syndrome. Analyzed mean IVPs during TUR vary between 11 and 35 cmH O but are mostly kept below 30 cmH O. Mean maximum IVPs during TUR range from 20 to 55 cmH O. Maximum IVPs seem to be lower when surgeons utilize continuous flow resection, and irrigation pressures are kept low. The results demonstrate a strong correlation between IVP levels and fluid absorption. IVP increase remains a neglected predictor of transurethral procedure complications, and endourologists should consider its intraoperative monitoring. Further research is necessary to quantify generated pressures and introduce means of controlling them.

Radiological parameters predicting a postoperative stone-free status (SFS) or a complicated perioperative course of mini-PNL, are scarce. Our aim was to identify such factors for prone 17.5F mini-PNL. A monocentric cohort of 103 cases was retrospectively analysed for factors predicting SFS and relevant complications, i.e. Clavien-Dindo (CD) ≥ 2. Parameters measured on preoperative supine CT included maximal stone diameter, skin-to-stone distance (SSD), ideal tract length (ITL), access angle, minimal T12-Lower Kidney Pole distance (T12LP) and minimal Iliac Crest-Lower Kidney Pole distance (ICLP). Infundibulopelvic angle (IPA) was measured on intraoperative pyelography. The median maximal stone diameter was lower in cases with postoperative SFS [16mm (Min. 10; Max. 35) vs. 20mm (Min. 6; Max. 85), p = 0.0052]. CD ≥ 2 was more frequent in cases with a bigger stone burden [19mm (Min. 13; Max. 85) vs. 16mm (Min. 6; Max. 49), p = 0.0056] and with the ribs in the access angle [7/23 (30.43%) vs. 8/76 (10.53%); p = 0.0454]. T12LP significantly differed in cases with and without CD ≥ 2 [80.48mm (± 21.31) vs. 90.43mm (± 19.42), p = 0.0397]; however, it had no influence on SFS (p > 0.05). SSD, ITL, IPA and ICLP were significant regarding neither SFS nor CD ≥ 2 prevalence (p > 0.05). Using multivariate logistic regression, T12LP was confirmed as an independent predictor on CD ≥ 2 prevalence. Preoperative computed tomographic factors indicating elevated kidney position influence perioperative course of mini-PNL. T12LP and the presence of ribs in the access angle are, apart from stone diameter, the most useful indicators for cases at risk of CD ≥ 2.

Melanoma antigen gene A2 (MAGE-A2) is one of the most cancer-testis antigens overexpressed in various types of cancers. Silencing the MAGE-A2 expression inhibited the proliferation of prostate cancer (PCa) cells and increased the chemosensitivity. However, the expression pattern of MAGE-A2 in PCa tissue samples and its prognostic and therapeutic values for PCa patients is still unclear. In this study, for the first time, the staining pattern and clinical significance of MAGE-A2 were evaluated in 166 paraffin-embedded prostate tissues, including 148 cases of PCa and 18 cases of high-grade prostatic intraepithelial neoplasia (HPIN), by immunohistochemical analysis. The simultaneous expression of both nuclear and cytoplasmic patterns of MAGE-A2 with different staining intensities was observed among studied cases. Increased expression of MAGE-A2 was significantly found in PCa tissues compared to HPIN cases (P < 0.0001). Among PCa samples, the strong staining intensity of nuclear expression was predominantly observed in comparison with cytoplasmic expression in PCa tissues (P < 0.0001). A significant and inverse correlation was found between the cytoplasmic expression of MAGE-A2 and increased Gleason score (P = 0.002). Increased cytoplasmic expression of MAGE-A2 was associated with longer biochemical recurrence-free survival (BCR-FS) and disease-free survival (DFS) of patients (P = 0.002, P = 0.001, respectively). In multivariate analysis, Gleason score and cytoplasmic expression of MAGE-A2 were independent predictors of the BCR-FS (P = 0.014; P = 0.028, respectively). Taken together, cytoplasmic expression of MAGE-A2 was inversely proportional to the malignant grade and duration of recurrence of the disease in patients with PCa. Taken together, cytoplasmic expression of MAGE-A2 was inversely proportional to the malignant grade and duration of recurrence of the disease in patients with PCa. Opioid abuse remains a serious public health problem. The pseudoirreversible mu opioid receptor antagonist methocinnamox (MCAM) might be useful for treating opioid abuse and overdose. Because endogenous opioid systems can modulate cognition and decision-making, it is important to evaluate whether long-term blockade of mu opioid receptors by MCAM adversely impacts complex operant behavior involving memory. This study tested the effects of MCAM in rhesus monkeys responding under a delayed matching-to-sample task, with correct responses reinforced by sucrose pellets. Because MCAM did not alter performance, antagonism of the rate-decreasing effects of morphine was used to confirm that an effective dose of MCAM was administered. Moreover, the muscarinic receptor antagonist scopolamine and the N-methyl-D-aspartate antagonist phencyclidine were studied as positive controls to demonstrate sensitivity of this procedure to memory disruption. Neither MCAM (0.32mg/kg) nor morphine (1-5.6mg/kg) impaired delayed matching-to-sample accuracy.
