We present a patient with left-sided obstructed megaureter secondary to neuropathic bladder. He was referred for technetium-99m dimercaptosuccinic acid ((99m)Tc-DMSA) renal cortical scintigraphy to evaluate renal cortical function. Images obtained 4 hr after injection showed significant activity in the dilated left ureter. When the ureter is visualized on DMSA scan, obstructive megaureter shoul...

Spinal neurons processing information from the ureter have been characterized in rats 1-4 days after the implantation of an experimental ureteric stone and compared with those of normal rats. The effects of a conditioning noxious stimulation of the ureter in the presence of the hyperalgesia evoked by the calculosis also were examined. Extracellular recordings were performed at the T12-L1 segmen...

A case of a lobulated polypoid tumor of the ureter showing histologically high grade malignancy is reported. Such a tumor is rare in the bladder, and to date none have been documented in the ureter. This tumor is probably the most malignant urothelial tumor of the inverted type in the urinary tract, including inverted papilloma.

OBJECTIVE Herein we report an additional case of a seminal vesicle cyst with ipsilateral renal agenesis and ectopic ureter in an asymptomatic individual with a normal examination. METHODS We review the literature on retrovesical mas regarding the embryology, evaluation, management and treatment.. RESULTS/CONCLUSIONS Seminal vesicle cysts with ipsilateral renal agenesis and ectopic ureter m...

Pig ureters were made to propagate injected fluid boluses by electrical stimulation in vitro. The propagation velocity was determined from EMG measurements made at several points along the ureter. It was found that this velocity varied both along the ureter and as a function of time, and that it was related to the contraction pressure but not to the bolus size.

Foreign bodies placed into the ureter are uncommon. Unintentionally placed nonabsorbable sutures may cause obstruction and stone formation. If not recognized, the patient may become symptomatic. We present a diagnosis of a rare case from Turkey, in which a ureter stone was formed by a nonabsorbable suture in a male patient with a previous laparotomy.

at 30 minutes after intravenous administration of the glomerular renal agent tc-99m-dtpa, both right and left lateral views were obtained. we analyzed the ratio of optical densities (behind the ureter/in front of the ureter). in patients without gross renal failure or retroperitoneal disease, the ratio was always less than 1 (range 0.38 to 0.95, mean 0.68). this represents greater perfusion of ...

Abstract Aim The aim of this communication is to present an exceptionally rare type hernia and its surgical management. Material methods We report the case a 66-year-old male with recurrence inguinal hernia. A routine Computed Tomography scan revealed as incidental finding ureter forming loop within sac. Additional findings included pyelocaliceal duplicity ureteropelvic dilatation. Results An a...

Renal-cell carcinoma (RCC) with synchronous metastasis to contralateral ureter is extremely rare with only four cases reported in the literature. We report a case of synchronous metastatic RCC to the contralateral ureter with effective robot-assisted retroperitoneoscopic nephron-sparing surgery that leads to favorable oncologic and functional outcome.

Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? The resection of the distal ureter and its orifice is an oncological principle during radical nephroureterectomy which is based on the fact that it represents a part of the urinary tract exposed to a considerable risk of recurrence. After removal of the proximal part it is hardly pos...
