Laparoscopic vs open radical nephroureterectomy for upper urinary tract urothelial cancer: oncological outcomes and 5-year follow-up.

Objective: To compare the oncological outcomes of laparoscopic radical nephroureterectomy (LNU) vs open NU (ONU) for upper urinary tract transitional cell carcinoma (TCC).

Patients And Methods: Between July 1999 and January 2003, we performed 70 LNUs and 70 ONUs for TCC of the upper urinary tract. ONU was reserved for patients with previous abdominal surgery or with severe cardiac and/or pulmonary problems.

Huge isolated port-site recurrence after laparoscopic partial nephrectomy: a case report.

A 66-yr-old man with pain and swelling in the right flank was referred to our clinic for diagnosis. In 2005, the patient underwent a laparoscopic partial nephrectomy for renal cancer of the lower pole of the right kidney. A computed tomography scan revealed a 20-cm tumor in the right abdominal wall, resulting in a suspected diagnosis of port-site metastasis from the first laparoscopic operation.

Retroperitoneal malignant solitary fibrous tumor of the small pelvis causing recurrent hypoglycemia by secretion of insulin-like growth factor 2.

A 28-yr-old man presented with recurrent reduced consciousness, generalized seizures of unknown etiology, recurrent hypoglycemia, psychomotor retardation, and grade 2 ectasia of the left kidney. Abdominal computed tomography (CT) and positron emission tomography (PET) scans demonstrated a well-circumscribed suprapubic pelvic mass, measuring 18 x 15 x 11 cm, with involvement of para-aortic lymph nodes and dilatation of the left ureter suggestive of an extragonadal testicular tumor. We excised the tumor by laparotomy, and it was confirmed to be a solitary fibrous tumor (SFT).
