Illumination matters Part II: advanced comparative analysis of flexible ureteroscopes in a kidney model by PEARLS.

Purpose: The aim of the study was to evaluate illumination properties in an in-vitro kidney calyx model in saline.

Design And Methods: We evaluated a series of contemporary flexible ureteroscopes including the Storz Flex-Xc and Flex-X2s, Olympus V3 and P7, Pusen 7.5F and 9.

Pulsed Thulium:YAG laser - What is the lithotripsy ablation efficiency for stone dust from human urinary stones? Results from an in vitro PEARLS study.

Background: The novel pulsed thulium:yttrium-aluminum-garnet (p-Tm:YAG) laser was recently introduced. Current studies present promising p-Tm:YAG ablation efficiency, although all are based on non-human stone models or with unknown stone composition. The present study aimed to evaluate p-Tm:YAG ablation efficiency for stone dust from human urinary stones of known compositions.

Pseudo-Renal Failure in the Context of Traumatic Bladder Rupture.

The bladder is both an intraperitoneal and extraperitoneal structure. Its anatomical position increases its risk of rupture. The resultant urine leak or extravasation can be intraperitoneal, extraperitoneal, or even both-with the former leading to more sinister outcomes.

Can the introduction of single-use flexible ureteroscopes increase the longevity of reusable flexible ureteroscopes at a high volume centre?

Objectives: To assess whether the introduction of single use flexibles ureteroscopes (su-fURS) at our high-volume centre had an advantageous impact on the turn-over and breakage rates of reusable fURS (re-fURS).

Methods: We analysed re-fURS number of usages and breakages at our centre between February 2015 and December 2018. We recorded the number of usages for analysed scope between the first usage until a breakage requiring reconditioning.

Treatment Options for Calyceal Diverticula.

Purpose Of Review: Calyceal diverticula are rare entities that can pose a significant challenge when it comes to their management. We analyse and summarise the literature with a focus on recent advances in the management of calyceal diverticula and discuss the advantages and disadvantages of each surgical technique.

Recent Findings: The identification of calyceal diverticula requires a certain level of suspicion and contrast-enhanced imaging.

Association of One-Step Nucleic Acid Amplification Detected Micrometastases with Tumour Biology and Adjuvant Chemotherapy.

One-step nucleic acid amplification (OSNA) is an intraoperative technique with a high sensitivity and specificity for sentinel node assessment. The aim of this study was to assess the impact of OSNA on micrometastases detection rates and use of adjuvant chemotherapy. A retrospective review of patients with sentinel node micrometastases over a five-year period was carried out and a comparison of micrometastases detection using OSNA and H&E techniques was made.

Fistula formation between the external iliac artery and ileal conduit following a radical cystoprostatectomy: a rare complication with prewarning signs of haemorrhage.

A 76-year-old man was admitted with bleeding per-urostomy following a collapse at home. Three weeks prior to the admission, he had undergone a radical cystoprostatectomy and formation of ileal-conduit for an extensive bladder carcinoma. A CT angiogram revealed a possible small source of bleeding within the ileal-conduit itself, which settled with conservative management.

The prevalence of malnutrition and fat-soluble vitamin deficiencies in chronic pancreatitis.

Background: Patients with chronic pancreatitis are at risk of malnutrition and nutrient deficiency due to malabsorption, pain, and poor diet. We sought to examine fat-soluble vitamin levels and malnutrition parameters in patients with chronic pancreatitis.

Materials And Methods: In a prospective controlled cohort study, 128 subjects (62 chronic pancreatitis patients and 66 age-/sex-matched controls) were recruited.

High prevalence of osteoporosis in patients with chronic pancreatitis: a systematic review and meta-analysis.

Background & Aims: Patients with chronic pancreatitis may be at high risk for osteoporosis and osteopenia. We performed a systematic review and meta-analysis to determine the prevalence of osteoporosis and osteopenia in patients with chronic pancreatitis.

Methods: Articles were identified from MEDLINE, EMBASE, and SCOPUS databases (through October 2012) and a manual search of the literature.

Assessing appropriateness of parenteral nutrition usage in an acute hospital.

Background: Although parenteral nutrition (PN) has become an integral component of patient care, the risks and costs associated with this therapy must be weighed against the benefits. The Department of Nutrition and Dietetics at our tertiary referral, university-affiliated hospital has audited the use of enteral nutrition and PN based on criteria devised from guidelines developed by the American Society for Parenteral and Enteral Nutrition (A.S.
