Paraganglioma, extra-adrenal pheochromocytomas, are relatively rare in adults, with most arising from para-aortic sympathetic and visceral organs, such as the bladder. Paraganglioma localized at the extravesical retroperitoneal pelvic cavity is extremely rare. We report a case of symptomatic perivesical pheochromocytoma in a 34-year-old man treated by surgical excision.

We present a case of locally recurrenced proximal-type epithelioid sarcoma that could be treated by regional excision alone. A 62-year-old man visited our institute for a growing mass in the perineal region.

Computed tomography showed a mass with a diameter of 6 cm adjacent to the stomach and the right adrenal tumor with a diameter of 3 cm. These tumors had similar characteristics in both plain and enhanced imagings.

Patients And Methods: A multi-institutional prospective trial was performed between July 2000 and May 2003 involving high-risk prostate cancer patients without metastasis, including 21 who received 8 months of NHT before radical prostatectomy. High-risk group was defined as clinical stage > or =T2c and/or prostate-specific antigen (PSA) >20 ng/ml and/or Gleason score > or =8.
Background: Open pyeloplasty has been the gold standard for surgical treatment of ureteropelvic junction (UPJ) obstruction, enjoying a long-term success rate exceeding 90%. Unfortunately, this procedure requires a muscle incision that entails some degree of morbidity. We have, therefore, investigated the feasibility of laparoscopic pyeloplasty for UPJ obstruction and report here the outcomes of our early cases.

Methods: Thirteen upper urinary tracts of 9 patients with cytologically diagnosed CIS, with concomitant bladder CIS in 4, were treated by intravesical BCG instillation. A DP catheter was placed retrogradely, and the appearance of vesicoureteral reflux was confirmed by cystography.
