MicroRNA in prostate cancer: from biogenesis to applicative potential
Luo X and Wen W
Prostate cancer is the most common solid malignant tumor in men, characterized by high morbidity and mortality. While current screening tools, such as prostate-specific antigen (PSA) testing and digital rectal examination, are available for early detection of prostate cancer, their sensitivity and specificity are limited. Tissue puncture biopsy, although capable of offering a definitive diagnosis, has poor positive predictive rates and burdens the patient more. Therefore, more reliable molecular diagnostic tools for prostate cancer urgently need to be developed. In recent years, microRNAs (miRNAs) have attracted much attention in prostate cancer research. miRNAs are extensively engaged in biological processes such as cell proliferation, differentiation, apoptosis, migration, and invasion by modulating gene expression post-transcriptionally. Dysregulation of miRNA expression in cancer is considered a critical factor in tumorigenesis and progression. This review first briefly introduces the biogenesis of miRNAs and their functions in cancer, then focuses on tumor-promoting miRNAs and tumor-suppressor miRNAs in prostate cancer. Finally, the potential application of miRNAs as multifunctional tools for cancer diagnosis, prognostic assessment, and therapy is discussed in detail. The concluding section summarizes the major points of the review and the challenges ahead.

Mucinous adenocarcinoma in kidneys with developmental anomalies - a report of two cases
Gali KV, Chawla A, Surag KR, Bhaskara SP and Hegde P
Primary mucinous adenocarcinomas of the kidney are rare and pose a challenge for preoperative diagnosis. The histogenesis of these tumours remains largely unknown, with three proposed theories: chronic irritation, differentiation of celomic epithelium, and kidney maldevelopment. Here, we present two cases of renal mucinous adenocarcinoma in patients with developmental renal anomalies, specifically a duplex collecting system and a horseshoe kidney.
Multidrug resistance in urinary E. coli higher in males compared to females
Khanal N, Cortie CH, Story C, Jones S, Mansfield KJ, Miyakis S and Keighley C
Urinary tract infections (UTIs) are common however the widespread use of antibiotics has led to a rise in antimicrobial resistance (AMR) amongst uropathogens, rendering a significant proportion of infections resistant to first line treatment. AMR in UTIs may differentially affect men and women, younger and older patients. The purpose of this study was to investigate MDR (multi-drug resistance) and AMR in males and females in an Australian health district.

The relationship between map scores and complications after standard percutaneous nephrolithotomy
Yazar VM, Gercek O, Topal K, Ulusoy K and Uzun R
Upper urinary tract stones are a common condition in urology clinics. Percutaneous nephrolithotomy (PCNL) is an effective procedure frequently used for the treatment of stones larger than 2 cm. MAP scoring is used to predict oncological outcomes and intraoperative complications after partial nephrectomy by using the thickness and adhesion of perinephric adipose tissue. We examined the relationship between MAP score and clinical and demographic findings of the patients, especially postoperative Hgb drop and postoperative complications.

Metoclopramide for analgesia in renal colic: a narrative systematic review
Tabner A, Ganesh A, Hobbs L, Prasanna Ponna N, Reed MJ, Fakis A, Toft S and Johnson G
Metoclopramide, a prokinetic antiemetic with activity at multiple receptor types, may be a useful treatment for renal colic pain. This review investigated whether metoclopramide is an effective analgesic in the management of adults with renal colic.Eligible studies were randomised, quasi-randomised or case-control trials of metoclopramide for the management renal colic pain. Electronic database searches were performed in November 2022. Screening was performed by two authors independently; disagreement was resolved by discussion or by adjudication by a third author. The Cochrane Collaboration Risk of Bias Tool v2.0 was used to assess bias.Two studies were included, enrolling 279 patients. Heterogeneity of primary outcome measurement and comparators rendered meta-analysis inappropriate; a narrative review is presented. Both studies showed some evidence of analgesic effect. The largest study had a low risk of bias in all assessed domains, whilst the smaller study was at a high risk of bias.There is limited evidence that metoclopramide may be an effective analgesic in the management of renal colic, with the highest quality study demonstrating analgesic properties similar to an intravenous non-steroidal anti-inflammatory medication.Protocol registration Prospero (CRD42022346618).
