A Fetus with Imperforate Anus Developing Pulmonary Hypoplasia Triggered by Transient Urethral Obstruction.

Case Rep Obstet Gynecol 2021 13;2021:9950578. Epub 2021 May 13.

Department of Obstetrics and Gynecology, Faculty of Medicine, The University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo 113-8655, Japan.

Pulmonary hypoplasia is a rare entity in a fetus with imperforate anus. The fetus was diagnosed with high-type imperforate anus with rectourethral fistula based on the dilated fetal bowel and the presence of bowel calcification at 19 weeks of gestation. As gestation advanced, fetal ultrasonography demonstrated development of pulmonary hypoplasia, progressive bowel dilation, and persistent oligohydramnios from 28 weeks of gestation despite a fluid-filled bladder without hydroureter or hydronephrosis.

Nephrogenic diabetes insipidus in children (Review).

Exp Ther Med 2021 Jul 11;22(1):746. Epub 2021 May 11.

Department of Genetics, 'George Emil Palade' University of Medicine, Pharmacy, Sciences and Technology, 540142 Târgu Mureş, Romania.

Nephrogenic diabetes insipidus (NDI) is characterized by impaired urinary concentrating ability, despite normal or elevated plasma concentrations of the antidiuretic hormone, arginine vasopressin (AVP). NDI can be inherited or acquired. NDI can result from genetic abnormalities, such as mutations in the vasopressin V2 receptor () or the aquaporin-2 (AQP2) water channel, or acquired causes, such as chronic lithium therapy. Read More

Case report: The theory of post-ileocystoplasty spherical configuration in patients with low-capacity bladder.

Int J Surg Case Rep 2021 Apr 5;81:105731. Epub 2021 Mar 5.

Division of Urology, Department of Surgery, Faculty of Medicine, Universitas Sumatera Utara - Haji Adam Malik General Hospital Medan, Jl. Bunga Lau No.17, Kemenangan Tani, Kec. Medan Tuntungan, Kota Medan, Sumatera Utara, 20136, Indonesia. Electronic address:

Introduction: Bladder augmentation can be performed by detubularization of the small or large intestine. A large capacity bladder is necessary to avoid frequent urination; thus, the ileal sac must be able to store the maximum volume of urine with relatively low pressure and the shortest length of the intestine. The acceptable pressure capacity should always be under ureteric pressure to avoid back pressure and kidney damage. Read More

A case of congenital ureteral atresia causing rare upper and lower urinary tract manifestations in a puppy: a case report.

BMC Vet Res 2021 Feb 9;17(1):73. Epub 2021 Feb 9.

Department of Small Animal Clinical Sciences, Virginia-Maryland College of Veterinary Medicine, Virginia Tech University, Virginia, Blacksburg, USA.

Background: Ureteral atresia is the congenital absence of a ureteral opening, resulting in a blind-ended ureter that fails to terminate at the urinary bladder. Consequently, severe hydroureter and hydronephrosis occur ipsilateral to the atresic ureter. However, hydronephrosis contralateral to severe hydroureter, although reported in humans, is not documented in the dog. Read More

Ureteroiliac artery fistula caused by full-length metallic ureteral stenting in a malignant ureteral obstruction: a case report.

J Med Case Rep 2020 Oct 19;14(1):195. Epub 2020 Oct 19.

Department of Urology, Kagawa University Faculty of Medicine, 1750-1 Ikenobe, Miki-cho. Kita-gun, Kagawa, 761-0793, Japan.

Background: The metallic stent is a new device for relieving the urinary tract in patients with malignant ureteral obstruction with short life expectancy and has been used frequently worldwide for its efficacy and safety. A ureteroarterial fistula with indwelling ureteral stent is rare but highly fatal, and there are several reports of ureteroarterial fistula treated by conventional polymer stents, although there are no reports on metallic stents. To our knowledge, this paper describes the first case of a ureteroiliac artery fistula caused by a full-length metallic ureteral stent in malignant ureteral obstruction. Read More

Placement of ureteral stents in three rabbits for the treatment of obstructive ureterolithiasis.

J Small Anim Pract 2020 Aug 7. Epub 2020 Aug 7.

Department of Veterinary Clinical Sciences, Faculty of Veterinary Medicine, Université de Montréal, 3200 rue Sicotte, St-Hyacinthe, Quebec, J2S 2M2, Canada.

Management of ureteral obstruction with stenting is often associated with a lower rate of complications than ureterotomy in domestic carnivores, but this treatment has not been previously evaluated in rabbits. Three rabbits (7, 6 and 10 years old) were diagnosed with unilateral obstructive ureterolithiasis associated with hydronephrosis and hydroureter on abdominal ultrasound. Decreased overall renal function was confirmed in all three cases. Read More

Unilateral Nonconfluent Cluster of Micronodules: Atypical Radiologic Appearance of Pulmonary Tuberculosis in an Immunocompetent Patient.

Case Rep Med 2020 30;2020:3708252. Epub 2020 Jun 30.

Department of Radiology, Faculty of Medicine, Universiti Teknologi MARA, UiTM Sungai Buloh Campus, Sungai Buloh 47000, Selangor, Malaysia.

Active pulmonary tuberculosis involving the lung parenchyma is typically seen on CT as consolidation, centrilobular nodules with tree-in-bud branching, cavitating lesions, and miliary nodules. However, some atypical CT patterns of granulomatous disease including tuberculosis have been recently described, namely, clusters of nodules without confluence or with confluence. We present a case of a patient who was found to have nonconfluent clusters of micronodules in the right lung with negative sputum culture for tuberculosis. Read More

Complete Erosion of an Aortobifemoral Bypass Graft Limb into Duodenum.

Ann Vasc Surg 2020 Aug 20;67:564.e9-564.e11. Epub 2020 Mar 20.

Department of Vascular Surgery, Royal Prince Alfred Hospital, Camperdown, New South Wales, Australia.

A 67-year-old male with a history of aortobifemoral bypass graft (ABF) for critical limb ischemia 10 months prior at a regional hospital was transferred to our center with 1 week history of rigors and 3 months of a chronic discharging left groin sinus. Two months prior he had a right-sided ureteric stent inserted for ureteric obstruction. Routine bloods revealed an acute-on-chronic renal injury and subsequent noncontrast computed tomography (CT) demonstrated left-sided hydroureter and hydronephrosis suggestive of extrinsic compression by the left bypass graft limb.

Jakaya Kikwete Cardiac Institute, Dar es Salaam, Tanzania.

Globally, schistosomal infections affect over 200 million people resulting in the loss of 70 million disability-adjusted life years. In the sub-Saharan Africa region, where over 85% of the global schistosomal infections are found, it is estimated that about 120 million people become symptomatic, over 20 million have severe disease, and nearly 200 000 die every year. Renal impairment is a severe consequence of schistosomiasis occurring in about 6% of all infected individuals and in 15% of those with the hepatosplenic form. Read More
