Acute suprarenal aortic occlusion is a rare but often catastrophic event. Despite immediate treatment, mortality and morbidity are high. We present a case of acute suprarenal aortic occlusion presenting with renal failure and dyspnea but without lower limb ischemia. Diagnosis was initially not taken in consideration. The patient required hemodialysis and temporary mechanical ventilation. After 13 days, an abdominal ultrasound was performed which revealed thrombosis of the suprarenal abdominal aorta. Suprarenal aortic thrombectomy was performed followed by aortobi-iliac bypass grafting. Diuresis returned 4 hr after surgery, and the patient fully recovered. Thorough review of the literature revealed only 8 cases of acute suprarenal aortic occlusion. Only 3 patients survived. To our knowledge, this is the first reported case of acute suprarenal occlusion, in which renal function could be restored after a 14-day period of anuria. The case illustrates that in select cases with prolonged acute renal failure aortorenal revascularization can be performed successfully., (Copyright © 2016 Elsevier Inc. All rights reserved.)

We report on emergency percutaneous renal artery stenting in two children who developed acute anuria due to bilateral renal artery stenosis and near-total occlusion. In both children, urine output could be reestablished following the procedure. One patient died from persistent severe cardiac failure. Emergency stenting is feasible, and may buy time for future procedures., (Copyright © 2013 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.)

Unlabelled: Bilateral obstructive nephrolithiasis is a rare cause of acute kidney injury (AKI) in early childhood. As soon as the identification of AKI secondary to ureteral stone is made, it will necessitate an emergency treatment., Patients: We report three infants with AKI caused by bilateral obstructive ureteral cystine stones. They were diagnosed with acute post-renal injury due to obstructive bilateral ureteral stones based on ultrasound scan findings. Immediately, bilateral ureteral stents were inserted for urinary drainage. Once renal function recovered to normal, each patient underwent ureteroscopy and percutaneous nephrolithotomy at the same session. Cystinuria was diagnosed by stone analysis and increased urinary excretion of cystine. Patients were advised to maintain a high fluid intake and were treated with potassium citrate in addition to tiopronin., Conclusions: With these three cases we would like to emphasize the importance of urolithiasis in the differential diagnosis of acute renal failure in young children, since urolithiasis may only cause nonspecific symptoms in this population. An early diagnosis with prompt treatment and a close follow-up are the key for achieving the best long-term outcome in cystinuria., (Copyright © 2012 Journal of Pediatric Urology Company.

Percutaneous suprapubic catheterization is an alternative when placement of a urethral catheter is contraindicated or unsuccessful. We report the case of a 3-day-old newborn, who presented anuric acute renal failure secondary to placement of a suprapubic catheter. An excessive length of catheter had been inserted into the bladder and was obstructing the vesicoureteral junctions. Several measures can be taken to prevent this complication, such as systematic measurement of the length inserted into the bladder, use of a catheter with 1cm gradations or recourse to radiopaque material., (Copyright © 2012 Elsevier Masson SAS.

Objective: To demonstrate a rare case of urological pathology, we report a combination of a single kidney and ureteral atresia. The treatment concept and outcome are outlined., Patient and Method: Antenatal ultrasound had revealed urinary ascites which lead to caesarean section in the 34th gestational week. Persisting anuria was confirmed postnatally and peritoneal dialysis started on the second day of life. Subsequent laparotomy revealed ureteral atresia after 3 cm of patent ureter. We created an ileum conduit after discussing various other therapeutic options., Result and Conclusion: A follow up of 12 months has shown steady function of the stoma with stable renal parameters. An ileal conduit represents a good option if high drainage is necessary in early childhood., (Copyright © 2011 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.)

A retrospective analysis of the frequency of requests for an intravenous urogram (I.V.P.) in men with acute retention of urine showed that this investigation was performed in 82%. In no instance, however, did the urographic findings influence the decision to operate or the type of operation performed. The introduction of a specialised urological service did not reduce the number of I.V.P.s requested because most referrals to the urologist were made after the I.V.P. Patients who had an I.V.P. waited on average 8 days from admission to operation compared with 3-5 days for those who did not. We conclude that no purpose is served by a routine I.V.P. in every male patient admitted to hospital with acute retention of urine.
