Changes in renal Doppler ultrasonographic parameters in patients managed with rigid ureteroscopy.

Changes in renal Doppler ultrasonographic parameters in patients managed with rigid ureteroscopy. Acta Radiol. 2013 Feb 27; Authors: Tokgöz O, Tokgöz H, Unal I, Voyvoda N, Serifoglu I Abstract BackgroundThere has been no study evaluating the intrarenal hemodynamic changes after ureteroscopy in the published literature.PurposeTo determine preoperative and postoperative intrarenal vascular parameters such as resistive index (RI), pulsatility index (PI), peak systolic velocity (PSV), end-diastolic velocity (EDV), measure changes on these values (ΔRI, ΔPI, ΔPSV, ΔEDV) after ureteroscopy (URS) and compare the outcomes with the results of normal contralateral kidneys, and finally investigate possible parameters that would affect renal vascular resistance changes.Material and MethodsWe prospectively studied 47 patients who underwent rigid URS. Preoperative gray-scale and Doppler ultrasonography (CDUS) measurements were obtained 24 h before URS. Similarly, postoperative CDUS measurements were done 24 h after the operation. The degree of hydronephrosis and location of stones in the obstructed kidneys, diameters of both kidneys, and thickness of renal parenchyma were evaluated with gray-scale US followed by CDUS with calculation of the intrarenal RI, PI, PSV, and EDV values for each kidney.ResultsFor the operated kidneys, statistically significant P values were noticed when RI and PI values were considered (P

In this manuscript, we describe a proband with a clinical diagnosis of congenital MMIHS and two rare compound heterozygous loss of function variants in MYL9, which we confirmed to be in trans by parental testing. To our knowledge, this is only the second peer ‐reviewed report of a genetically characterized case of MYL9‐associated MMIHS and supports the gene‐disease association between MYL9 and MMIHS with an autosomal recessive inheritance pattern. We conclude that MYL9 be targeted on genetic testing panels for MMIHS, smooth muscle myopathies, and c ardiovascular phenotypes. AbstractMegacystis –microcolon–...

ConclusionSignificant renal anomalies were identified in first-degree relatives of children with non-syndromic CAKUT and hence, attempts must be made to screen the family members of children with non-syndromic CAKUT.

ng Po-Tsang Lee Ketamine-associated diseases have been increasing with the rise in ketamine abuse. Ketamine-associated uropathy is one of the most common complications. We investigated the effects of ketamine-associated uropathy on renal health and determined predictors of renal function decline in chronic ketamine abusers. This retrospective cohort study analyzed 51 patients (22 with ketamine-associated hydronephrosis and 29 with ketamine cystitis) from Kaohsiung Veterans General Hospital in Taiwan. Primary renal outcome was end-stage renal disease or estimated glomerular filtration rate decline >30% from bas...

Abstract Urinothorax [UT], the accumulation of urine in the pleural space, is an uncommon cause of pleural effusions resulting from trauma, obstruction, or iatrogenic causes. Thoracentesis with pleural fluid analysis and evaluation of biochemical characteristics, such as pleural fluid creatinine (PCr) to serum creatinine ratio (Scr), is necessary to establish this diagnosis. This case illustrates a 93 year old man with a complicated past medical history including chronic kidney disease stage 4, adenocarcinoma of the prostate status post brachytherapy complicated by proctitis, high grade transitional cell carcinoma...

A case is described of a 4 year-old girl who presented with chronic episodic abdominal pain with vomiting. Physical examination was unremarkable aside from hypertension. Point-of-care renal ultrasound showed hydronephrosis, leading to a diagnosis of ureteropelvic junction obstruction presenting with Dietl crisis (episodic abdominal pain secondary to urinary tract obstruction). The clinical utility of point-of-care renal ultrasound in the evaluation of abdominal pain and ultrasound findings of ureteropelvic junction obstruction are highlighted.

Despite surgery, there was continuous progression of the left hydronephrosis. Referral to a tertiary hospital because of continued sterile pyuria prompted investigation for tuberculosis (TB):...

Conclusions: In neonates with bilateral UPJO, the worse affected kidney is operated first, as it still has the potential to recover. The contralateral milder UPJO unit is known to recover spontaneously following unilateral pyeloplasty. In those with bilateral Grade 4 UPJO and mass, bilateral pyeloplasty is feasible. Alternatively, unilateral pyeloplasty + contralateral cystoscopic retrograde stenting may prevent rupture or functional deterioration in the opposite kidney.

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 AND 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, ren...
