OBJECTIVE To evaluate predictive factors for retrograde ureteral stent failure in patients with non-urological malignant ureteral obstruction. MATERIALS AND METHODS Between 2005 and 2014, medical records of 284 malignant ureteral obstruction patients with 712 retrograde ureteral stent trials including 63 (22.2%) having bilateral malignant ureteral obstruction were retrospectively reviewed. Re...

Partial nephrectomy was performed on a patient of twelve years, having adenocarcinoma of kidney with duplex ureter. The two segments of kidney had independent blood supply. Operation was based on the evidence that if adenocarcinoma is localized to the kidney, then removal of the involved kidney alone is associated with long term survival (JPMA : 34 39, 1 984).

BACKGROUND Vesico-ureteral reflux (VUR) is a dynamic event in which a retrograde flow of urine is present into the upper tracts. VUR may occur isolated or in association with other congenital abnormalities or as part of syndromic entities. We present a patient with a bilateral primary VUR, syndromic disease caused by a large deletion of 18q (18q21.3-qter) and terminal duplication of 1p (1p36.32...

Bedside ultrasound is becoming a very important tool in emergency medicine. One of the staples of bedside ultrasound is its potential in assisting the clinician with information on local anatomy and organ function. A previously healthy 44-year-old male presented to the emergency department with acute dysuria and left flank pain. A renal bedside ultrasound was obtained and showed excellent urine...

30 cases of obstructing proximal ureteral stones at the level of l3-l5 which could not be pushed back into the pelvis and passed by a guide wire under epidural anesthesia, were removed percutaneously with the rigid ureteroscope. multiple stones in one ureter, bilateral ureteral stones and a ureteral stone of a solitary kidney were removed successfully in one session showing the reliability and ...

INTRODUCTION Until now, peristalsis has been the only known method of urine transport. The main objective of this paper was to study urinary tract function - especially the upper urinary tract, the ureter - from a new mechanical point of view. The physical (physical dual valves) and biological basis (biological dual valves) of a new functional model is presented based on previous observations a...

The retrocaval ureter is a rare congenital entity, classically managed with open pyeloplasty techniques. The experience obtained with the laparoscopic approach of other more frequent causes of ureteropelvic junction (UPJ) obstruction has opened the method for the minimally invasive approach of the retrocaval ureter. In our paper, we describe a clinical case of a right retrocaval ureter managed ...

     Urethralduplication is a rare condition occurs as a congenital malformation either independently or in the setting of other congenital malformations such as caudal duplication syndrome. Its prevalence becomes even rarer if it manifests as two side-by-side tracts in coronal plan.Nonetheless, we introduce a unique presentation of complete coronal urethral duplication accompanied by astoundin...

double-j (dj) stents are the main tools used in urological practice for prevention and treatment of obstruction. stenting is also mandatory after complicated ureteroscopy or tul (transureteral lithotripsy). known complications are upper migration of dj stents into the kidney and lower migration to the bladder. in a man with an impacted right lower ureteral stone, a dj stent was placed because t...
