Objectives: Evaluating the morphology of the upper urinary tract of renal living-related donors with 64 Multi - Detectors Computed Tomography (MDCT). Subjects and methods: From 01/2017 to 10/2018, when carrying out a prospective study at Cardiovascular Centre of Hue Central hospital, we have performed 64 MDCT of the upper urinary tract (MDCT-UUT) on 312 renal living-related donors among which, there are 265 males and 47 females aged from 20 to 60. Results: 100% of donors experience no contrast-induced artifacts in renal parenchyme. 71.47% of visualization of contrast media (CM) of entire upper urinary tract filling and 100% of visualization of CM of top half upper urinary tract filling in both of kidney. The majority of donors have single collecting system (99.04% in right kidney and 99.68% in left kidney). The rest has partial or complete duplex collecting system. 64 MDCT has high value in detecting stone of the upper urinary tract (8.01%) in comparison with KUB Radiograph (0%) and abdominal Ultrasonography (0.32%). 100% of donors have normal renal function in the excretory phase at 5 minute after CM and NaCL 0.9% injection bolus. This allows reducing examination time and radiation exposure with the highest effective dose 5.88mSv in unenhanced and excretory phases. Conclusions: 64 MDCT-UUT contributes into more accurate diagnosis of the morphology of the upper urinary tract of renal living-related donors, helps surgeons make appropriate planning in the operation of chosen kidneys of living-related donors and transplanting into patients. Key words: Upper urinary tract - 64 MDCT - MDCT-UUT

Objectives: Evaluating the anatomy variation of renal artery system of living-related donors with 64-slice renal Computed Tomography Angiography (CTA). Subjects and methods: From 01/2009 to 12/2013, when carrying out a prospective study at Cardiovascular Centre of Hue Central hospital, we have performed 64-slice renal CTA on 160 living-related donors among which, there are 118 males and 42 females aged from 19 to 56. Results: The majority of donors have simple anatomy variation of renal artery with one hilar artery (71.87% in right kidney and 65.62% in left kidney). The rest has complex variation with two hilar arteries and accompagnied with upper or lower polar branch (28.13% in right kidney and 34.38% in left kidney). The minimum diameter of the renal artery is 1.3mm. The nearest distance of proximal branching from the hilar artery is 1.6mm. The furthest distance of two arteries is 65mm. Conclusions: 64-slice renal CTA contributes into more accurate diagnosis of anatomy variation of renal artery system of living-related donors, helps surgeons make appropriate planning in the operation of chosen kidneys of living-related donors and transplanting into patients. Key words: anatomy variation, renal artery system, CTA

An unusual presentation of colorectal metastasis to the upper urinary tract is reported. The metastasis manifested as a filling defect seen during antegrade pyelography. Cytologic evaluation of aspirated material demonstrated metastatic colonic adenocarcinoma. A dilated collecting system may be caused by intraluminal material including tumor and blood clots. Whenever fixed filling defects are encountered, urine cytology should be sent even in the absence of renal parenchymal involvement by tumor. The cytological evaluation may allow for prompt diagnosis and treatment.

In a prospective study, twenty children with a mean age of 4 years were treated with pivmecillinam, 25 mg to 40 mg per kilogram body-weight and day, for acute pyelonephritis. Urine cultures yielded growth of E. coli in sixteen instances, Klebsiella spp. in two, S. saprophyticus in one and a mixed Gram-positive flora in one patient. All children fulfilled the diagnostic criteria for upper urinary tract infection. In all cases where Gram-negative pathogens were responsible, the infections were eradicated. One reinfection was registered in a child with a concomitantly discovered congenital urological malformation. Pivmecillinam also cured one patient infected with S. saprophyticus but was ineffective in the case of mixed Gram-positive flora. It is concluded that pivmecillinam is a valuable new drug for the management of pyelonephritis in children, as most of these infections are caused by Gram-negative organisms.

Mitomycin C as a treatment for superficial bladder carcinomas and upper urinary tract tumours has been linked to local adverse events. Systemic toxicity has been documented for just a very few cases. This report presents a case of interstitial pneumonitis accompanied by myelosuppression in a 74-year-old patient after receiving the fifth administration of mitomycin C through a ureteral catheter as a treatment for left kidney pyelocaliceal urothelial carcinoma. Therefore, suspecting mitomycin C toxicity, urinary tract instillations were discontinued, and intravenous filgrastim and methylprednisolone were initiated. Currently, after five months since the last mitomycin C urinary tract instillation, the patient is still receiving filgrastim and corticosteroids. A moderate effort dyspnoea persists despite interstitial pulmonary infiltrates have presented a very important reduction. Pancytopenia has also persisted. Blood count and lung function monitoring would be appropriate in patients undergoing mitomycin C instillations, especially in those with established prior lung disease.

Duplication of the collecting system is the most common congenital abnormality of the upper urinary tract (0.8-2%), with unilateral duplication more common than bilateral [1-4]. In complete duplication, ureters typically follow the Weigert-Meyer rule of the upper pole inserting caudomedial (may be obstructed) and the lower pole inserting craniolateral (may reflux) in the bladder. Very rarely is there deviation from this pattern. Few cases of uncrossed double ureters with lower pole dysplasia, ureterocele, or ectopia have been reported [5-8]. We report a breach in the law with a case of an asymptomatic 1-month old new-born male with lower pole ureteral ectopia and obstruction. We discuss the importance of thorough work up with emphasis on differential diagnoses and care team-based decisions in the evaluation of paediatric hydronephrosis.

Urolithiasis poses an acute life threatening emergency and most frequently obstructs the lower urinary tract in male dogs (Franti et al., 1999). It has been reported that the upper urinary tract calculi are uncommon in dogs and cats with majority of uroliths (Osborne and Fletcher, 1995). The most probable causes include infections, nutritional deficiencies and mineral imbalances. The mineral deposits which form in the bladder of male dogs get flushed out of the bladder with urine and lodge in the penis just behind the os penis which is the most commonly reported site of obstruction followed by ischial arch (Franti et al., 1999). Diagnostic imaging techniques like radiography and ultrasonography are sensitive in diagnosis, with abdominal ultrasonography having 90% sensitivity, 98% specificity and 97% accuracy (Webb, 2000). Treatment of urolithiasis can be attempted by retrograde urethral hydropropulsion for urethroliths followed by cystotomy (Osborne et al., 1999), failing of which urethrotomy or urethrostomy is indicated (Smeak, 2000). Other techniques like bladder marsupialization, surgical tube cystostomy and minimal invasive surgical tube cystostomy with their short and long-term complications have been attempted. However, in this study the cases were relieved by retrograde urethral hydropropulsion, cystotomy and urethrotomy.
