INTRODUCTION: Ureteropelvic junction obstruction is a pathology typically diagnosed in childhood. Nevertheless, some clinically silent cases may be unnoticed until adulthood. CASE DESCRIPTION: We report the case of a 53-year-old female with hydronephrosis due to ureteropelvic junction stenosis diagnosed in the adulthood, who subsequently developed obstruction with progressive worsening of renal function without symptoms. CONCLUSION: The natural history of ureteropelvic junction obstruction is still obscure...

A pathologic kidney with hydronephrosis is prone to rupture after minor trauma to the renal pelvis ; however, it is controversial whether drainage, such as nephrostomy and ureteral stenting, should be performed in this setting. Herein we report traumatic rupture of the renal pelvis in 2 patients with ureteropelvic junction stenosis at two centers. Case 1 : A 15-year-old boy sustained a blunt injury on his left back while playing football. His family physician referred the patient to our hospital for suspected left renal injury...

INTRODUCTION: Failed pyeloplasty procedures are caused by large amounts of scarring, and peripelvic fibrosis. This finding has been associated with urinary extravasations to the operation, urosepsis or an excessive tissue reaction. The treatment options for secondary UPJO (Ureteropelvic Junction Obstruction) are the same with the options for primary procedures: in cases of very poor renal function, various pyeloplasty forms (open and laparoscopic), and ureterocalicostomy or sometimes nephrectomy may be considered in severe renal function loss...

Ureteral obstruction is one of the most common urological complications after kidney transplant. The definitive treatment of ureteral obstruction has been surgical revision. Because of the increased morbidity of surgery, minimally invasive percutaneous procedures have gained more acceptance in recent years. Presently, interventional radiological procedures are recommended as the first step in treatment of ureteral obstructions. Ureteral occlusions or near-occlusion high-grade stenoses require greater catheter backup force...

Percutaneous endoscopic renal surgery such as percutaneous nephrolithotomy (PCNL) is a safe and effective treatment for patients with large and/or complex renal calculi. However, a unique set of complications can occur with this surgical approach that may involve the targeted kidney and surrounding structures. Renal collecting system obstruction after PCNL is rare, but may result from ureteral avulsion, stricture formation, transient mucosal edema, blood clot, or infundibular stenosis. Impaction of stone and trauma during PCNL could induce stricture formation and obstruction...

A 71-year-old woman presented at our institution with the chief complaints of left back pain and fatigue. Radiographic examination revealed left ureteral stenosis close to ureteropelvic junction of the lower-pole with a left incomplete duplicated collecting system. Transurethral retrograde balloon dilatation under general anesthesia was performed, and a ureteral stent was inserted to the lower-pole; however, there was urinary leakage from the upper-pole at the dilated ureteral stenosis lesion, and therefore, another ureteral stent was inserted to the upper-pole just after the first stent insertion...

INTRODUCTION: Gross hematuria caused by rupture of an artery in the urinary tract is a rare but potentially fatal condition. Iliac artery aneurysms, pelvic surgery with radiation, vascular reconstructive surgery, surgery for stenosis of the ureteropelvic junction, and transplantation are reported to be associated with this condition. In the vascular reconstructive surgery group, the most common etiology is rupture of the degenerated artery or synthetic graft in the ureter. CASE PRESENTATION: We present a case of rupture of the small anastomotic pseudoaneurysm at the proximal anastomosis of a right iliofemoral autogenous vein extra-anatomic graft in the urinary bladder...

Ureteropelvic junction (UPJ) stenosis is the most common cause of pathological neonatal hydronephrosis. UPJ obstruction may be treated conservatively in some cases, but surgery is indicated if symptoms occur or renal function deteriorates. Pyeloplasty is the procedure of choice for UPJ stenosis. Pyeloplasty can be performed by open laparoscopic or robotic technique. The laparoscopic technique is safe and may be associated with shorter length of hospital stay and reduced complications. Lately, robotic pyeloplasty has been performed with similar results, adding the benefits of easier suturing maneuverability, but with increased costs...

Ureteral injury can be classified as iatrogenic or traumatic, which represents a rare but challenging field of reconstructive urology. Due to their close proximity to vital abdominal and pelvic organs, the ureters are highly susceptible to iatrogenic injury, while ureteral injury caused by external trauma is relatively rare. The signs of ureteric injury are difficult to identify initially and often present after a delay. The treatment of ureteral injury, which is depended on the type, location, and degree of injury, the time of diagnosis and the patient's overall clinical condition, ranges from simple endoscopic management to complex surgical reconstruction...

OBJECTIVE: The most common cause of urinary obstruction is ureteropelvic junction (UPJ) obstruction. In short stenosis, a dismembered pyeloplasty is performed, but for long segment stenosis, the procedure is not well defined. We present the reverse flap ureteroplasty method, which we prepared from the pelvis for use in long segment UPJ obstruction. METHODS: Between 2007 - 2016, we operated on 6 cases (4 males, 2 females) with an age range of 2 - 6 months. After reaching the UPJ region, depending on the length of the long segment obstruction, a flap measuring 25 - 35 mm in length was prepared from the pelvis so that its width would be 10 - 12 mm on the pelvis side and 10 mm in the distal portion...
