Background & Aims: Hydronephrosis is a common problem in prenatal and newborn infants diagnosed by ultrasonography. Bladder to ureter reflux, the upper or lower urinary tract obstruction, and neurogenic bladder are the most common causes of hydronephrosis in newborns and infants. Methods: In this study, 100 neonates and infants with hydronephrosis were observed clinically and laboratorically fo...

INTRODUCTION In males the ectopic ureter usually drains into the prostate (50%). During ureteric developement a thin membrane (Chawalla's membrane) separates the lumen of the ureter and the urogenital sinus at the point where the ureter joins the urogenital sinus. This membrane ruptures allowing urin to drain from the ureter to the urogenital sinus. The authors reported a case of renal dysplasi...

BACKGROUND There is a paucity of data addressing the blood supply in the surgically reconstructed ureter, and complete lack of microangiographic studies of the reconstructed ureter with the use of a free bladder mucosa flap. The present study evaluated the blood supply in the reconstructed dog ureter after a 5-centimeter segment resection, supplemented by a tube constructed from a free bladder ...

A 30-year-old-man who initially presented three years previously to the emergency department with right loin pain and a three-month history of haematuria. He reported no other urinary symptoms and was otherwise fit and well with no significant past medical history. Flexible cystoscopy was unremarkable and evaluation with ultrasound and a computed tomography (CT) scan demonstrated a large right-...

Duplex collecting systems are the most commonly encountered anomaly of the urinary system. Complete duplex system with an H shaped ureter is a very rare situation. There are only two reported H ureter cases in the literature. Herein, we aimed to present an H shaped ureter case, which was identified while performing ureterorenoscopy to a 48-year-old female patient due to a right distal ureteral ...

Inguinoscrotal herniation of the ureter is a rare finding with the potential for serious surgical complications. Two anatomic forms are defined. In the more common paraperitoneal variant, the herniating peritoneal sac drags the ureter and sometimes other abdominal structures with it. The uncommon variant--extraperitoneal inguinal herniais without a peritoneal sac and consists of the ureter and ...

A case of huge primary leiomyoma of the ureter in which nephroureterectomy was performed is presented. To the best of our knowledge, this case is a unique form of leiomyoma of the ureter due to its large size. There have been only twelve cases of primary leiomyoma of the ureter reported since 1955 and eleven of them were very small and one was big in size but smaller than the present case. Our ...

Urolithiasis is one of the most common diseases seen by urologists. In 28% patients with kidney stones, disease symptomatic. The benefits ureteral stone extraction include minimal invasiveness, a shorter postoperative recovery time, and favourable safety profile. Aim: to compare evaluate relationship between density ureter, calculus, its localization value creatinine level predicting success ur...

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...

Chronic schistosomiasis of the urinary tract can present with symptoms unrelated to the disease. A 33-year-old man from Edo State Nigeria presented with recurrent left flank pain. Laboratory investigations did not reveal any cause. Radiological investigation revealed a stricture of the left ureter and hydronephrosis of the left kidney. Management included surgical excision and antischistosomias...
