“…Third, although the CT or MRI images showed that all patients had renal pelvis or calyx dilation with proximal ureteral dilatation, we could not review the ultrasound images because our hospital does not retain ultrasound images. A previous study demonstrated that ultrasound and CT scans had different sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio for the diagnosis of hydronephrosis (31). This might be a limitation because some patients were diagnosed only by ultrasound.…”

Preoperative hydronephrosis predicts adverse pathological features and postoperative survival in patients with high-grade upper tract urothelial carcinoma

et al. 2021

Purpose: Epidemiological studies reported confl icting results about preoperative hydronephrosis in upper tract urothelial carcinoma (UTUC). This study aimed to investigate the association between preoperative hydronephrosis and pathologic features and oncologic outcomes in patients with UTUC treated by radical nephroureterectomy (RNU). Materials and Methods: This was a retrospective, single-center cohort study of 377 patients treated by RNU without perioperative chemotherapy between January 2001 and December 2014. Logistic regression, Cox regression, and survival analyses were performed. Results: Among the 226 patients with high-grade UTUC, 132 (58%) had preoperative hydronephrosis. Multivariable logistic regression revealed that hydronephrosis was independently associated with advanced pT stage (P=0.017) and lymph node or lymphovascular invasion (P=0.002). Median follow-up was 36 months (interquartile range: 20-48 months). The 3-and 5-year overall survival (OS) rates in patients with hydronephrosis were signifi cantly lower than in those without hydronephrosis (both P <0.001). The 3-and 5-year cancer-specifi c survival (CSS) rates in patients with hydronephrosis were signifi cantly lower than in those without hydronephrosis (both P=0.001). Hydronephrosis was independently associated with OS and CSS (P=0.001 and P=0.004, respectively). Among the 151 patients with low-grade UTUC, hydronephrosis was not associated with pathologic features and postoperative survival. Conclusions: Preoperative hydronephrosis was signifi cantly associated with adverse pathologic features and postoperative survival in patients with high-grade UTUC.

“…Moderate hydronephrosis was defined as the blunting or rounding of the calices or the obliteration of renal papillae without affecting the cortical thickness. Severe hydronephrosis was considered to be present if caliceal ballooning and cortical thinning were found [ 14 ]. We also collected data on stone location (calculus at the junction of the renal pelvis, multiple renal pelvis stones), operation time (>60 min, ≤60 min), intraoperative bleeding (>100 ml, ≤100 ml), intraoperative perfusion pressure (≤30 mmHg, >30 mmHg), and pyonephrosis.…”

Clinical Assessment of Risk Factors for Renal Atrophy After Percutaneous Nephrolithotomy

Background This study explored the risk factors for renal atrophy after percutaneous nephrolithotomy (PCNL), and provides a reference for clinical prevention of renal atrophy after PCNL. Material/Methods According to the inclusion and exclusion criteria, the clinical data of 816 patients who underwent PCNL in our hospital from May 2013 to February 2018 were retrospectively collected. Depending on whether the patient had kidney atrophy, they were divided into a renal atrophy group and a non-renal atrophy group. We collected and analyzed data on patient sex, age, kidney location, duration of disease, stone size, hydronephrosis, renal calculus position (renal ureteral junction or multiple pyelonephritis-associated stones), operation time, intraoperative blood loss, perfusion pressure, and pyonephrosis. The indicators with statistically significant differences were selected and multivariate logistic regression analysis was carried out to determine the risk factors for renal atrophy. Results Among 816 patients, 49 had renal atrophy and the incidence rate was 6.01%. Univariate analysis and multivariate logistic regression analysis showed that independent risk factors for renal atrophy after PCNL were: duration of the disease longer than 12 months (OR=4.216, P=0.003, 95% CI: 1.714, 7.354), perfusion pressure >30 mmHg (OR=3.895, P=0.001, 95% CI: 1.685, 8.912), moderate and severe hydronephrosis (OR=5.122, P<0.001, 95% CI: 1.847, 9.863), stones located at the junction of the renal pelvis (OR=3.787, P=0.001, 95% CI: 1.462, 7.654), stones located in multiple calyces (OR=4.531, P=0.014, 95% CI: 1.764, 8.196), and pyonephrosis (OR=10.143, P<0.001, 95% CI: 2.214, 16.248). Conclusions The main risk factors for renal atrophy after PCNL are: course of disease more than 12 months, moderate and severe hydronephrosis, pyonephrosis, multiple calyceal stones, stones at the junction of the renal pelvis, and intraoperative high perfusion pressure.

“…104 In addition, bedside abdominal ultrasound can be used to evaluate, quantify, and guide paracentesis for abdominal ascites. 6 POCUS also has been used to diagnose obstructive nephropathy, 6 hydronephrosis, 105 nephrolithiasis, 106 and bladder distention, 107 as well as assisting in difficult Foley catheter placement. 108 All of these attributes make abdominal ultrasound ideally suited for routine use in the ICU.…”

Point-of-Care Ultrasound (POCUS) is a valuable bedside diagnostic tool for a variety of expeditious clinical assessments or as guidance for a multitude of acute care procedures. Varying aspects of nearly all organ systems can be evaluated using POCUS and, with the increasing availability of affordable ultrasound systems over the past decade, many now refer to POCUS as the 21 st-century stethoscope. With the current available and growing evidence for the clinical value of POCUS, its utility across the perioperative arena adds enormous benefit to clinical decisionmaking. Cardiothoracic anesthesiologists routinely have used portable ultrasound systems for nearly as long as the technology has been available, making POCUS applications a natural extension of existing cardiothoracic anesthesia practice. This narrative review presents a broad discussion of the utility of POCUS for the cardiothoracic anesthesiologist in varying perioperative contexts, including the preoperative clinic, the operating room (OR), intensive care unit (ICU), and others. Furthermore, POCUS-related education, competence, and certification are addressed.
