“…The diagnostic approach for children with urolithiasis relies on ultrasonography and kidney-ureterbladder plain radiography (KUB). Ultrasound is the preferred test since it is noninvasive, easy and very effective [5]. However, the sensitivity of US in detecting ureter stones is low [6], as in case 3.…”

“…However, complications such as acute or chronic rejection, drug-induced renal injury, transplant kidney artery stenosis, BKV associated nephropathy (BKVAN), and renal disease recurrence should be ruled out, and a transplant kidney puncture biopsy may be performed if necessary. The ultrasonography is the preferred diagnostic method [ 9 ], shows the separation of renal pelvis or dilatation of ureter (Fig. 1 A), emission computed tomography (ECT) can distinguish functional or mechanical obstruction to a certain extent [ 8 ], magnetic resonance urography (MRU) can provide three-dimensional images and fully display the shape of stenosis site (Fig.…”

Background To explore the risk factors of ureteral stricture in transplant kidney and the clinical effects of different treatment methods. Methods The 62 patients with transplant kidney ureteral stenosis as the experimental group, and another group of recipients from the same donor as the control group (n = 59 cases). The risk factors for ureteral stricture and the survival rate of transplant kidney were analyzed and compared. The 62 patients were divided into open operation, luminal operation, and magnetic compression anastomosis (MCA) operation group. The effect of the operation and the survival rate of transplant kidney among the three groups were compared. Results In our study, we found that the above differences were statistically significant in clinical data such as gender, multiple donor renal arteries, history of infection, and delayed graft function (DGF) between the two groups (P < 0.05). Urinary tract infection and DGF history were the independent risk factors for the development of ureteral stricture. The open operation had the best treatment effect and the survival rate of the transplant kidney, followed by the MCA, the stricture recurrence rate in the luminal operation was the highest. Conclusion The ureteral stricture has a negative correlation with the long-term survival rate of the transplant kidney, the curative rate and long-term effect of open surgery are the best, stricture recurrence rate of luminal surgery is high, and it may require multiple operations in the future, the MCA is a new breakthrough and innovation in the treatment of ureteral stricture.

“…Many authors consider the poor-edge definition of two-dimensional TRUS (due to the thick plane of viewing and speckles are the main reasons for lesion disorientations), and the multiple trials in redirecting the tip of needle into the best point for drainage within the cavity of prostatic abscesses. [ 10 11 12 ] Transrectal sectional sonography (TRSS) is an upgrade of dimensional US (three-dimensional US) imaging, based on the production of real-time, multiresolution very thin (0.5-1 mm) contiguous optical slicing of the three-dimensional volume. Each slice has a specific color and represents a specific location on the reference plane.…”

Aim:The aim of this study was to assess the effectiveness of transrectal sectional sonography (TRSS) in the diagnosis and treatment of prostatic abscess.Materials and Methods:Eighteen patients with prostatic abscesEs were the material of the present study. The criteria of abscess collection within the prostate gland and the periprostatic tissues were confirmed by TRSS, which guided the aspiration in all patients.Results:Diagnosis and transperineal needle aspiration of prostatic abscesses were successful in all cases. After the second puncture procedure, recurrence noted in 2 (11.1%) out of 18 patients, who were further subjected to transurethral deroofing under TRSS vision. The amount of pus drained ranged between 3.6 and 29.3 mL (mean: 15.1 mLSD ± 1.5), compatible with the estimated volume by virtual organ computer-aided analysis three-dimensional measurements. The most frequently involved organism was Escherichia coli. All patients received intravenous antibiotics (third generation cephalosporin) after the midstream urine analysis and further proper antibiotics, according to the aspirated pus culture and sensitivity.Conclusions:Transrectal sectional sonography could be a more reliable method in the diagnosis of prostatic abscesses. It can provide precise needle-guides into the best drainage location of the abscess cavity and justify transurethral unroofing if persistent recurrence is there.
