Objectives: To study the effectiveness and reliability of a new minimally invasive technique for the treatment of the terminal ureter in nephroureterectomy due to transitional cell carcinoma, both in open and laparoscopic procedures.
Methods: Observational retrospective study of 14 patients that underwent intravesical sealing and endoscopic excision of terminal ureter, before ureterectomy (11 laparoscopic, 3 open), due to an upper urinary tract tumor, between July 2003 and November 2007. This procedure was performed on 11 males and 3 females, average age 59.
Objective: To find out the outcomes of endopyelotomy alter a long-term follow-up and determine the variables that may influence the results.
Material And Methods: We review the results obtained in 77 patients that underwent antegrade endopyelotomy with ureteropelvic junction obstruction, after 10-year follow-up. We used the Kaplan-Meier curve in order to determine the probable failure rate at a certain point.
Objectives: To report our experience with laparoscopic pyeloplasty in the treatment of pyeloureteral junction obstruction.
Methods: Between August 2001 and August 2004 14 patients with the diagnosis of pyeloureteral junction obstruction underwent laparoscopic repair. Seven cases had the obstruction on the left side and the other seven on the right side.
Objectives: To evaluate the role of ureteroscopy (rigid and flexible) in the follow-up protocol for transitional cell tumors treated conservatively in our department by endourological procedures, and to review the articles on this topic available in the literature.
Methods: From February 1997 to June 2003, 10 patients (12 renal units) with upper urinary tract urothelial tumor treated conservatively by endourological procedures were followed by cytology, cystoscopy, retrograde ureteropyelography, and ureteroscopy (rigid and flexible), quarterly during the first year, semi-annually during the second year, and yearly thereafter in order to detect tumor recurrence.
Results: Mean follow-up was 31.
Objectives: To report our experience with a series of 10 patients undergoing radical cystectomy with bladder substitution. We were supported by a better knowledge of the female continence anatomical mechanisms and the demonstration of the oncological viability of the urethral remnant.
Methods: From 1994 to 2002 10 women underwent radical cystectomy with bladder substitution by means of a modified anterior pelvic exanteration; technical modifications to achieve continence preservation are based on: preservation of the distal 2/3 of urethra, pubourethral ligaments and endopelvic fascia, and limitation of lateral vaginal dissection to avoid damage to the striated sphincter innervation.
