An 87-year-old female presented with complaints of intermittent severe right renal colic. CT imaging demonstrated a ureterosciatic hernia and moderate hydronephrosis proximal to the portion of the ureter that was herniated through the sciatic foramen. A retrograde pyelogram demonstrated a transition point in the ureter at the location of the hernia. A ureteral stent was placed resulting in stra...

Here we report a case of idiopathic retroperitoneal fibrosis, a unilateral case, which resulted in remission by ureterolysis with intraperitonealization. A 24-year-old female was hospitalized because of hydronephrosis. Many examinations were performed with the suspicion of malignant disease, but no apparent cause was detected. We suspected idiopathic retroperitoneal fibrosis and performed surgi...

We describe a case of a solitary functioning kidney with giant hydronephrosis secondary to ureteropelvic junction obstruction in a young girl who underwent successful robot-assisted tubularized flap pyelovesicostomy. The aim of this report was to highlight the feasibility and efficacy of this technique in salvaging such renal moieties and to present a brief review of the surgical options availa...

Intrauterine contraceptive device (IUCD) is a common method of contraception among women because of its low cost and high efficacy. Perforations are possible resulting in multiple complications including urinary complications. Obstructive hydronephrosis and hydroureter is one of the main clinical concerns in genitourinary practice leading to radiological investigations for determination of the ...

A case of retroperitoneal chronic expanding hematoma complicated with hydronephrosis, which was difficult to diagnose preoperatively, is reported. The patient was a 70-year-old man. An 18 cm mass was detected in the right retroperitoneal space on abdominal CT screening. There were small calcifications in the periphery of the mass that were strongly enhanced in the delayed phase of dynamic CT. T...

Hydronephrosis of the pelvi-ureteric type rarely presents in infancy. Nixon (1953) found only one case in a child under the age of 6 months out of 78 cases seen at The Hospital for Sick Children, Great Ormond Street, between 1929 and 1950. It is, however, a condition which can be treated by conservative surgery and it is important that it should not be overlooked. The following two cases of pel...

Hydronephrosis is one of the most common abnormalities detected on routine prenatal ultrasounds, being noted in up to 1% of fetuses. Rarely, severe hydronephrosis coexists with oligohydramnios, which portends a poor prognosis. We review the most recent literature on the results of prenatal intervention in this setting. Presently, the first randomized controlled trial to address whether prenatal...

A 1-month-old boy was referred to our hospital with right hydronephrosis. Excretory urography showed poor visualization of the right kidney and a filling defect in the bladder. Chromosomal analysis of peripheral blood revealed a karyotype of 49,XXXXY, and a diagnosis of 49,XXXXY Klinefelter s syndrome associated with hydronephrosis caused by intravesical ureterocele was made. 49,XXXXY Klinefelt...

Retrocaval ureter is a rare cause of hydronephrosis. Its rarity and non-specific presentation pose a challenge to surgeons and radiologists in making the correct diagnosis. Differentiation from other causes of urinary tract obstruction, especially the more common urolithiasis, is important for successful surgical management. Current practice has seen multislice computed tomography (MSCT) rapidl...

Congenital obstructive nephropathy is a common cause of chronic kidney disease and a leading indication for renal transplant in children. The cellular and molecular responses of the kidney to congenital obstruction are incompletely characterized. In this study, we evaluated global transcription in kidneys with graded hydronephrosis in the megabladder (mgb (-/-)) mouse to better understand the p...
