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

CONCLUSIONThis study demonstrated an optimal approach for relieving upper urinary tract obstruction and acute infection in which percutaneous nephrostomy drainage is preferred for patients with severe pyonephrosis, large stones (>10 mm) with high-grade hydronephrosis, steinstrasse, or failure in retrograde ureteric stent placement, while retrograde ureteral catheterization using cystoscopy is suitable for patients diagnosed with small stones (≤10 mm) and low-grade hydronephrosis.

This article will review the available evidence in relation to prevention of sepsis in cUTI, evaluating the risk factors associated with sepsis development. Published articles from January 2005 to September 2019 on UTIs and sepsis prevention in complicated UTIs were identified by using MEDLINE (National Library of Medicine Bethesda MD) and by reviewing the references of retrieved articles.Expert opinion: Prevention of sepsis relies on prompt and timely diagnosis of cUTI, early identification of the causative organism, removal of obstructions and source control, proper and adequate empirical/targeted antimicrobial treatment...

AbstractAntenatal hydronephrosis (AHN) is the most frequently detected abnormality by prenatal ultrasonography. Differential diagnosis of AHN includes a wide variety of congenital abnormalities of the kidney and urinary tract ranging from mild abnormalities such as transient or isolated AHN to more important ones as high-grade congenital vesicoureteral reflux or ureteropelvic junction obstruction. It is well known that the outcome depends on the underlying etiology. Various grading systems have been proposed for the classification of AHN on prenatal and postnatal ultrasonography. Mild isolated AHN represents up to 80% of c...

Duplicated renal collecting system is a urological anomaly often found in pediatric patients. It is less commonly diagnosed in adulthood, particularly in a pregnant patient. Many point-of-care ultrasonography users may not be aware of this diagnosis, particularly in patients in the emergency department. It is important to recognize the duplicated system because in general, patients will often have hydronephrosis in only one renal pole rather than the entire kidney, which corresponds to an unequal renal function as documented on renal nuclear medicine functional scans.

CONCLUSIONS: Phimosis, cryptorchidism, and voiding disorders are the most frequent pediatric urological reasons for consultation; primary care continuing medical education seems worthwhile. It would, perhaps, be more beneficial for all to have the pediatric urologists travelling to perform clinics and surgeries in distant regions to save more than 300 km round trip to several families.

We report the case of a 4-year-old boy who first presented with acute pyelonephritis at the age of 6 months. Diagnostic workup revealed high-grade bilateral vesicourethral reflux (VUR). At the age of 18 months, a bulking agent was used to treat bilateral VUR. Since the VUR persisted, an open bilateral Lich-Gregoir procedure was done at the age of 3 years. Immediately after surgery, he developed acute urinary retention with hydronephrosis that resolved with the placement of dwelling urinary catheter. After removal of the catheter urinary retention relapsed so placement of suprapubic urinary catheter was indicated since he d...

Studies have reported the usefulness and tolerability in practice of abdominal ultrasound performed by non-radiologists in various clinical situations. This prospective observational single-center study included 184 patients hospitalized in an internal medicine department who underwent conventional abdominal ultrasound. A medical resident with basic training performed point-of-care clinical ultrasound using a pocket-sized device. The concordance obtained between the researcher and the radiologist was good (k>0.6) for the gallbladder, splenomegaly, longitudinal diameter of the kidney, presence of renal cysts and hydronephrosis.
