INTRODUCTION: Uretero-ileal strictures (UES) following urinary diversion are therapeutically challenging. We compared the efficacy, safety and renal outcome following therapeutic endo-urological techniques (EUTs) and open surgical revision of the anastomosis (SRA) for UES. MATERIAL AND METHODS: We retrospectively analysed all EUTs and SRAs performed for UES in 2 hospitals between 1987 and 2015. Restenosis was defined as recurrent radiographically diagnosed hydronephrosis and re-intervention...

We report on a family in which initial features were compatible with Fryns syndrome. The first sibling was a stillborn female with a left diaphragmatic hernia (DH). Her clinical features overlapped with Fryns syndrome. The second pregnancy, a male fetus, was followed for polyhydramnios, hypoplastic mandible, mild enlargement of the fetal bladder, hydronephrosis, and rocker bottom foot deformities. He had facial features similar to his sibling and a large cleft of the secondary palate, small jaw, and secundum atrial septal defect...

A 26-year-old woman presented to our hospital with right costovertebral angle (CVA) pain. Ultrasonographyand computed tomography(CT) scan indicated right hydronephrosis, and MAG3 renogram showed an obstructed pattern in the right kidney. Enhanced CT scan revealed an ureteropelvic junction obstruction (UPJO) with an aberrant vessel. To clarifythe ureteropelvic junction (UPJ) structure in detail, we utilized 3D-CT with retrograde pyelography (RP), which further revealed the true pinhole ureteral stricture of UPJ unaffected bythe aberrant vessel...

Deep endometriosis is usually defined as endometriosis infiltrating the peritoneum by >5 mm. It sometimes involves the ureter causing hydronephrosis in 5% of cases. The latter is associated with 18% ureteral lesions. Ureteral endometriosis is one of the rare causes of silent Kidney failure. The ureter obstruction can lead to urinary tract obstruction, hydronephrosis and hydroureters. The ureters are usually compressed externally by the endometriotic lesions surrounding it causing extrinsic ureteral endometriosis, and sometimes by pressure from the bulky adenomyotic uterus with paraureteral fibrosis...

Ureterocele, which is a cystic dilatation of the terminal ureter, is usually associated with the upper moiety in a case of the duplex system. Giant hydronephrosis, a rare entity, is usually due to pelviureteric junction obstruction and is usually diagnosed in infants and children. We report a unique case of a unilateral complete duplex system with ureterocele with giant hydronephrosis of the upper moiety in an adult woman presenting as an abdominal lump. To the best of our knowledge, this is the first case of giant hydronephrosis associated with ureterocele in an adult patient...

Individuals suffering from chronic kidney disease (CKD) deal with major morbidity and mortality including poor exercise tolerance. A variety of factors including anemia, poor muscle mass, cardiovascular changes and limited physical activity contribute to exercise intolerance. Studies suggest that early initiation of aerobic and resistance training improves the muscle function, ability to tolerate exercise and quality of life in CKD patients. A thorough medical examination and exercise testing are recommended before initiating an exercise regimen in individuals with CKD...

BACKGROUND: The ureterointestinal anastomosis stricture (UAS) is a common complication of urinary diversion after radical cystectomy. For decades, open anastomotic revision remained the gold standard for the treatment of UAS. However, with the advancement in endoscopic technology, mini-invasive therapeutic approaches have been used in its management. Here, we report our experience with and long-term results of combined simultaneous antegrade and retrograde endoscopy (SARE) in the treatment of non-malignant UASs after urinary diversion in a consecutive series of patients...

The developing kidney is sensitive to both morphological and functional disturbances during the gestational and postnatal phases of growth and differentiation. Exposure to drugs or chemicals during these critical windows of renal development can result in aplasia, dysplasia, polycystic kidney disease, hydronephrosis, or other features characteristic of nephrotoxicity, including tubule dilation, necrosis, or mineralization. Functional effects can occur without associated morphological abnormalities. Differences in the timing of nephrogenesis and morphologic renal development among species help to explain specific phenotypes of various gestational and postnatal teratogens and nephrotoxins...
