Article Synopsis
- - Over the last 30 years, miniaturized percutaneous nephrolithotomy (mPCNL) has gained popularity due to its potential to reduce complications compared to standard procedures, but there's still debate over best practices and management strategies that hinders wider use.
- - An international panel of urology experts developed a consensus document on mPCNL to provide a comprehensive framework for practice, which included reviewing literature, identifying research gaps, and conducting surveys to gather expert opinions.
- - The study revealed 58 key questions on mPCNL practices, and consensus was achieved on 30 questions, affirming mPCNL as an effective technique for treating upper urinary tract stones in both adults and children.
Prostate cancer (PCa) is a common male malignancy and early diagnosis is crucial for successful treatment. The current study aims to validate results from a pilot study that demonstrated an inverse association between urine tyrosine and tryptophan levels and the severity of PCa. This study comprised a cohort of 97 patients with benign prostatic hyperplasia, 93 patients diagnosed with localized PCa, 75 patients diagnosed with locally advanced PCa, and 68 patients diagnosed with metastatic PCa.

However, high-quality evidence on the risk factors associated with US is currently lacking. We aimed to develop a consensus statement addressing the definition, risk factors, and follow-up management of iatrogenic US after endoscopic treatment for urolithiasis.

Methods: A specially designed water tank using 2 laparoscopic 5 mm ports and 2 different size (10 Fr and 8 Fr) sealing cap adaptors (SCA) as ureteral orifices was used to perform the test. A 10-12 Fr UAS was fixed to a load cell and the force of insertion (FOI) was continuously recorded with a digital force gauge.
