Advances in the treatment of melanoma are resulting in patients living for extended periods after being diagnosed with metastatic disease. Metastases to the ureter are rare, but they have been described in the literature on a number of occasions. In this case report, we describe a patient with established metastatic melanoma who, whilst taking and responding to immunomodulatory therapy, was fou...

BACKGROUND AND OBJECTIVES A patient with a solitary kidney, cysteine stones, and recurrent ureteral strictures underwent robot-assisted laparoscopic ureterectomy with ileal ureter formation. METHODS Using a transperitoneal, 4-port robotic approach, we removed the strictured ureter and created an ileal ureter. The ileal-pyelo and ileal-vesical anastomoses were performed using the robotic syste...

Introduction. Laparoscopic radical nephroureterectomy (LNU) is being increasingly performed at several centers across the world. We review oncologic outcomes after LNU procedure and the techniques for the management of distal ureter. Materials and Methods. A comprehensive review of the literature was performed on the oncological outcomes and management of distal ureter associated with LNU for u...

in an upward and outward direction. Anterior extension involves the bladder base and causes malignant ulceration of the bladder. A severe cystitis leads to vesico-vaginal fistula, ascending infection, pyelo-nephritis and death. Extension in an upward and outward direction in the broad ligament leads to encroachment on the ureter, which may become infiltrated by malignant tissue. Following obstr...

A 28-year old man presented with left flank pain and dysuria. Plain abdominal film and computed tomography showed a left giant ureteral stone measuring 11.5 cm causing ureteral obstruction and other stones 2.5 cm in size in the lower pole of ipsilateral kidney and 7 mm in size in distal part of right ureter. A left ureterolithotomy was performed and then a double J stent was inserted into the u...

The aim of this study was to compare two different acellular scaffolds: natural and synthetic, for urinary conduit construction and ureter segment reconstruction. Acellular aortic arch (AAM) and poly(L-lactide-co-caprolactone) (PLCL) were used in 24 rats for ureter reconstruction in both tested groups. Follow-up period was 4 weeks. Intravenous pyelography, histological and immunohistochemical a...

Spontaneous rupture of the ureter is extremely uncommon and thought as a nontraumatic leakage of the urine from the ureter. It is usually secondary to ureteral obstruction from a calculus. The symptom is always severe and drainage or surgical intervention is often required. True rupture of upper ureter or renal pelvis may be confused with a physiologic phenomenon of the forniceal rupture with u...

Ureter injuries are uncommon but dreaded complications in gynecologic surgery and a frequent cause of conversion to laparotomy. Recently, a few papers reported the repair of gynecologic ureteral injuries using laparoscopy with encouraging results. In these case reports, we aimed to present two laparoscopically repaired ureter injuries during total laparoscopic hysterectomies (TLH). In the first...
