Acute Hydronephrosis Secondary to Methadone-Induced Constipation.

Cureus 2022 May 17;14(5):e25090. Epub 2022 May 17.

Medicine, Montefiore Medical Center, Wakefield Campus, Bronx, USA.

Opioid-induced constipation is a significant medical problem accounting for over 40% to 60% of patients without cancer receiving opioids. We report a unique case of a 71-year-old male with a history of opioid use disorder now on methadone maintenance presenting with severe opioid-induced constipation and fecal impaction causing extrinsic compression on the right-sided ureter resulting in right hydronephrosis and hydroureter that improved with aggressive bowel regime with the stool softener, laxatives and enemas. Methadone alone can predispose to hydroureter with hydronephrosis due to external compression from the severe intestinal dilation secondary to opioid-induced constipation. 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
