Simultaneous laparoscopic nephroureterectomy and cystectomy: a preliminary report

PURPOSE: Patients with muscle-invasive bladder cancer and concomitant upper urinary tract tumors may be candidates for simultaneous cystectomy and nephroureterectomy. Other clinical conditions such as dialysis-dependent end-stage renal disease and non-functioning kidney are also indications for simultaneous removal of the bladder and kidney. In the present study, we report our laparoscopic experience with simultaneous laparoscopic radical cystectomy (LRC) and nephroureterectomy. MATERIALS AND METHODS: Between August 2000 and June 2007, 8 patients underwent simultaneous laparoscopic radical nephroureterectomy (LNU) (unilateral-6, bilateral-2) and radical cystectomy at our institution. Demographic data, pathologic features, surgical technique and outcomes were retrospectively analyzed. RESULTS: The laparoscopic approach was technically successful in all 8 cases (7 males and 1 female) without the need for open conversion. Median total operative time, including LNU, LRC, pelvic lymphadenectomy and urinary diversion, was 9 hours (range 8-12). Median estimated blood loss and hospital stay were 755 mL (range 300-2000) and 7.5 days (range 4-90), respectively. There were no intraoperative complications but only 1 major and 2 minor postoperative complications. The overall and cancer specific survival rates were 37.5 percent and 87.5 percent respectively at a median follow-up of 9 months (range 1-45). CONCLUSIONS: Laparoscopic nephroureterectomy with concomitant cystectomy is technically feasible. Greater number of patients with a longer follow-up is required to confirm our results.

Comparison of radical prostatectomy techniques: open, laparoscopic and robotic assisted: [review]

INTRODUCTION: To review the current status of laparoscopic radical prostatectomy (LRP) and robotic assisted radical prostatectomy (RALP) in relation to radical retropubic prostatectomy (RRP) in the management of localized prostate cancer. MATERIALS AND METHODS: Between 1982 and 2007 published literature was reviewed using the National Library of Medicine database and the following key words: retropubic, laparoscopic, robotic, robot-assisted, and radical prostatectomy. Special emphasis was given to the technical and cost considerations as well as operative, functional and oncologic outcomes. In particular, reports with pioneering work that have contributed to the evolution of the technique, presenting comparative outcomes and with large series encompassing intermediate/long term follow-up, were taken into account. RESULTS: After intermediate term follow-up, LRP and RALP achieved similar oncologic and functional results compared to RRP. However, LRP and RALP were associated with decreased blood loss, faster convalescence and better cosmetics when compared to RRP. The RALP technique is undoubtedly more expensive. CONCLUSIONS: The oncologic and functional outcomes for LRP and RALP are similar to RRP after intermediate term follow-up. Long term follow-up and adequately designed studies will determine the inherent advantages and disadvantages of the individual techniques in the management of localized prostate cancer.

Laparoscopic partial cystectomy for urachal and bladder cancer

PURPOSE: To report our initial experiences with laparoscopic partial cystectomy for urachal and bladder malignancy. MATERIALS AND METHODS: Between March 2002 and October 2004, laparoscopic partial cystectomy was performed in 6 cases at 3 institutions; 3 cases were urachal adenocarcinomas and the remaining 3 cases were bladder transitional cell carcinomas. All patients were male, with a median age of 55 years (45-72 years). Gross hematuria was the presenting symptom in all patients, and diagnosis was established with trans-urethral resection bladder tumor in 2 patients and by means of cystoscopic biopsy in the remaining 4 patients. Laparoscopic partial cystectomy was performed using the transperitoneal approach under cystoscopic guidance. In each case, the surgical specimen was removed intact entrapped in an impermeable bag. One patient with para-ureteral diverticulum transitional cell carcinoma required concomitant ureteral reimplantation. RESULTS: All six procedures were completed laparoscopically without open conversion. The median operating time was 110 minutes (90-220) with a median estimated blood loss of 70 mL (50-100). Frozen section evaluations of bladder margins were routinely obtained and were negative for cancer in all cases. The median hospital stay was 2.5 days (2-4) and the duration of catheterization was 7 days. There were no intraoperative or postoperative complications. Final histopathology confirmed urachal adenocarcinoma in 3 cases and bladder transitional cell carcinoma in 3 cases. At a median follow-up of 28.5 months (range: 26 to 44 months), there was no evidence of recurrent disease as evidenced by radiologic or cystoscopic evaluation. CONCLUSIONS: Laparoscopic partial cystectomy in carefully selected patients with urachal and bladder cancer is feasible and safe, offering a promising and minimally invasive alternative for these patients.
