To assess the influence of the ureter on renal washout during 99mTc-DTPA diuresis renography, ureteral images were reviewed in 42 children (median age: 5 mo) referred for hydronephrosis. Sixty-minute acquisitions were obtained in hydrated patients under bladder drainage. Furosemide was injected at 30 min. An abnormal ureter was defined as an intense and continuous image of greater than 10 min. ...

This is to describe a case of a morbidly obese (BMI = 40) female with retrocaval ureter treated with laparoendoscopic single-site surgery. A JJ stent was positioned. A 2 cm umbilical access was created. A single port platform was positioned. The entire ureter was mobilized posterior to the vena cava and transected where the dilated portion ended. The distal ureter was repositioned lateral to th...

Carcinosarcomas of the ureter are rare biphasic neoplasms, composed of both malignant epithelial (carcinomatous) and malignant mesenchymal (sarcomatous) components. Carcinosarcomas of the urinary tract are exceedingly rare. We report a unique case of a carcinosarcoma of the ureter with a chondrosarcoma and small cell tumor component arising in a 68-year-old male who presented with microscopic h...

INTRODUCTION Complete ureteral avulsion is one of the most serious complications of ureteroscopy. The aim of this report was to look for a good solution to full-length complete ureteral avulsion. CASE PRESENTATION A 40-year-old man underwent ureteroscopic management. Full-length complete avulsion of ureter occurred during ureteroscopy. Pyeloureterostomy plus greater omentum investment outside...

Med., 1977, 123 (1), 9-22 An extraluminal ureteral bipolar needle "indwelling" electrode with recording wire was devised to study the ureteral function, and daily recording of the ureteral myogram in human and experimental animal has...

FOR several centuries physiologists have concentrated their researches on the production of urine by the kidney. Many theories have been formulated, and it now seems to be established that this is a process of filtration and selective reabsorption. The problem cannot yet be said to have been completely elucidated. Perhaps partly because of the exhausting nature of their researches, and the lack...

We present a case of vaginal ectopic ureter with ipsilateral partial duplication of the upper ureter (Y-type ureter), ipsilateral hypoplastic pelvic kidney and bicornuate uterus in a 20-year-old woman who presented with mild urinary incontinence since infancy. Ultrasonography, computed tomography and intravenous pyelography examination showed a left kidney with no evidence of a right kidney. Cy...

Ureteral injury is a rare but potentially serious complication that can occur during a variety of abdominal and pelvic surgical procedures. Knowledge of the course of the ureter is the first step toward preventing ureteral injuries. While some injuries are noticed intraoperatively, most are missed and present later with pain, sepsis, urinary drainage, or renal loss. The choice of treatment is b...
